What are the characteristics of the vertical packing machine configuration? Many people who want to buy packaging machines will definitely encounter vertical packaging machines when they consult some packaging machine manufacturers. So, what is a vertical packaging machine and what is its specific configuration?
Vertical packaging machine refers to the feeding by the material stretching feeding device during the packaging process. The plastic film passes through the film cylinder to form a tube shape, and the side is sealed by the hot vertical sealing device. Cut the package length and position according to the color label photoelectric detection device.
• How to choose the right model of machine?
The vertical packaging machine model is defined according to the maximum film width. For example, the maximum acceptable film width of the VS-720 packaging machine is 300mm-700mm.
• Know the bag width and how to calculate the film width
When calculating the film width, look at the bag type. Generally, the film width consists of two parts, namely the bag width * 2 and the sealing roll width * 2. If it is an angle, add another angle.
• What are the common optional devices for vertical packaging machines?
Gusseting device / Punching device / Upper feeding device / Under bag device / Nitrogen filling device / Exhaust device / Bagging device / Easy tear device / Upper hopper vibration device / Heat transfer printer / Dust removal device Waiting / bag making device / vacuum.
• What is the function of the bag-making device?
For relatively fluffy or long-shaped materials, the bag can be dipped into the bottom of the bag through the patting device to facilitate the sealing of the roller and the cutting of the bag with a cutter.
• What is the function of the feeding device?
Some single materials are heavier, such as potatoes and nuts. It is easy to smash the singles. Loading materials can prevent the materials from smashing the bag. For the target weight is relatively heavy, the sealing properties of the sheet are not good, the inner PE is relatively thin, the material is easy to break through the horizontal seal, and the material can also be used.
Another situation is that the material cannot be dropped at one time, and sometimes it will affect the sealing. It can use a feeding device to help the sealing roller to block a part of the material to prevent the material from falling into the middle of the sealing while it is being sealed.
• What is the function of the lower bag device?
When the target weight of the material exceeds 1kg, the dragon's whisker supporting the bag cannot stably support both sides of the bag, which may easily cause wrinkles in the horizontal seal, which is not beautiful. At this time, it is necessary to hold the bag to bear a part of the weight.
• What are the application limitations of the vacuum device?
Generally for non-fluffy materials such as beans, the target weight of the material should not be too heavy, exceeding 400g, the effect is not good. Because when the vacuum is drawn, the bag will become smaller and the whole bag will be lifted. If the bag is too heavy, it cannot be lifted well.
• What are the characteristics of PE film sealing device?
The PE film is easy to melt, and the temperature cannot be too high. As soon as the sealing roller touches the film, the film will melt. Therefore, it is necessary to quickly contact, fast seal, and quickly withdraw the sealing roller. The form of the seal is generally a line.
• Vertical packing machine has two kinds of cut shapes: zigzag and flat mouth.
Everyone will have a lot of trouble when cleaning the sheets. Because the area of the sheets is relatively large, they are usually washed with a washing machine. So what to do with yellowed sheets? How can you make your sheets look brand new?
We spend most of our time in bed, so the cleaning of bedding has a great impact on people's health and sleep.However,the fitted bed sheets are used for a long time, and stains and odors are inevitable. Although it can usually be cleaned, the effect is not ideal. Especially during the seasonal changes, the human body is more sensitive and more susceptible to bacterial attack, causing harm to health.
Most people think that long-lasting sheets are unhygienic and difficult to clean, and they usually throw them away.In fact,these fitted bed sheets don't need to be thrown away to avoid waste.
Tip one: Salt + baking soda
Prepare a basin of water, add some baking soda, and mix with edible salt and stir well. Soak the yellow sheets for half an hour, and then clean them by ordinary methods. After drying, the sheets will be as clean as new!'
Tip two: Orange Peel
Put the orange peel in the pot and boil it with water. After cooling, use it to soak and scrub the yellowed sheets. Then, rinse with water. This method not only cleans the sheets, but also contains a light fragrance.
Tip three: Rice water
Soak the sheets in rice water overnight and wash them the next day in the usual laundry sequence. During the cleaning process, you can rub more friction when you encounter a dirty place, which can basically be cleaned.
The above three are tips for cleaning old sheets, I hope to help you.
Doors have become a necessity in our lives. Not only to play a decorative role, but more importantly to ensure our safety. In today's life, as the partition decoration market is hot, aluminum alloy doors have become the darling of the door and window industry, and it has almost become the standard for kitchen and balcony partitions. It is not only economical and practical, but also greatly improves the face value of the house!
There are also many people complaining that the aluminum alloy doors installed in their homes for less than five or ten years are not as effective as before. In fact, as long as you regularly check the door and window accessories, replace the aging accessories, and pay attention to daily maintenance, you can extend the life of the accessories and solve the problem of poor sound insulation.
The quality of aluminum alloy doors is also the key to affecting the service life. How much do you know about aluminum glass doors?
What is an aluminum alloy door
Aluminum glass doors are a door frame member made of surface-treated aluminum alloy profiles through cutting, punching, milling, tapping, manufacturing and other processing technology. A door assembled by assembly. Including aluminum-wood composite door and aluminum-plastic composite door, which is made of aluminum alloy as the base material of the stress rod member.
According to the opening method, the classification of aluminum alloy doors
• Hinged door
Swing door refers to the door that is opened horizontally with the hinge as the axis. Swing doors are the most commonly used door. According to the different opening directions, it can be divided into two types: inside and outside. The opening direction of a swing door is mainly determined by its function and the need to occupy as little indoor space as possible after opening.
• Sliding door
Sliding door refers to the door that is opened and closed by sliding left and right along the width direction. There are two types of sliding doors: surface-mounted and concealed. Surface-mounted sliding doors refer to sliding doors and rails that are outside the wall, while concealed sliding doors refer to sliding doors with doors and rails in the middle of the wall.
• Folding door
A folding door is a door that can be folded during the opening process. It can be divided into two basic types: flat folding door and sliding pull door. Because the folding door can be folded when it is opened, it occupies a small space, which can often be used as an effective method to re-separate and combine the indoor space.
• Sliding door
The difference between sliding door type and sliding type lies in the opening method and material. Generally speaking, sliding door type is a combination of two doors that can only be moved from both ends and cannot be opened from the middle. The material is generally all glass, only The door frame and armrest are made of aluminum alloy, so they are often used as bathroom doors.
The push-pull aluminum alloy door is composed of two or more small doors, which can be pushed open from the middle, and the direction is relatively free. Each small door of the sliding door has an aluminum alloy door frame. Generally, there is no armrest, but it can be set on the door. Patterns or motifs to add beauty.
• Roll-pull
Roll-pull aluminum alloy door is also called rolling door. Rolling door is high in security and affordable, so it is often used in shopping malls or garages and other places that need to be closed in all directions.
Characteristics of aluminum alloy door
• Light weight and high strength
The material of aluminum alloy is mostly a combination of hollow core and thin wall, light weight, density is only 1/3 of steel, easy to use, and the section has high bending strength. The aluminum alloy sliding door is durable and has small deformation.
• Good sealing performance
The aluminum alloy itself is easy to extrude, the cross-section size of the profile is accurate, and the processing accuracy is high. The sealing groove fixing groove has been completed together with the cross section during the extrusion molding process, which has created favorable conditions for the installation of the sealing material, and the installation fit is also very high.
• Beautiful appearance
After the surface of the aluminum alloy is processed, it can show different colors such as golden, silver and white, with a large choice of space, bright and smooth after oxidation, and elegant decoration effect.
• Strong corrosion resistance
The aluminum alloy oxide layer does not fade, does not fall off, does not need painting, is easy to maintain, and requires almost no maintenance, which generally reduces the cost of decoration and use.
• Long life
After good surface treatment, aluminum profiles have good resistance to atmospheric corrosion, not afraid of humidity, not afraid of sunlight, high temperature does not deform, low temperature does not embrittle, does not burn, does not age, and is suitable for various climate environments.
In addition to paying attention to quality, consumers must also pay attention to the brand of the product. It is recommended to choose some relatively large brands as much as possible, it is best to go to regular stores to buy, not only the quality is guaranteed, the use is more secure and assured.
Parameters tell the cnc 3 axis engraving center every little detail about the specific machine tool being used, and how all CNC features and functions are to be utilized.
Parameters specify settings for every cnc 3 axis engraving center feature and function, and there are hundreds, even thousands, for any CNC. When discussing parameters, I always reiterate the importance of backing them up. As the person using the CNC, you are responsible for doing so. Today’s CNCs make it easy to back up to a flash drive, so there is no excuse not to do so. Plus, having your parameter backup can save hours, if not days, in the case of a CNC failure.
Nearly every CNC-related issue involves a parameter setting. Indeed, if the machine is misbehaving in any way, it is likely that an erroneous parameter setting is to blame. There are certain parameters that every CNC user should know related to safety, efficiency and simplifying machine usage.
1. Initialized states
Certain G-code modes are automatically instated when you power-on a machine tool. Absolute or incremental (G90/G91); inch or metric (G20/G21); rapid or linear motion (G00/G01); plane selection XY, XZ or YZ (G17/G18/G19); and feed per minute or feed per revolution (G94/G95), among others, are G-code modes that can can be specified through parameters.
2. Canned cycles
Most of these parameters control efficiency. For example, the machining center chip-breaking peck drilling cycle (G73) has a parameter that controls retract amount between pecks. The larger this value, the more time it will take to machine a hole. In similar fashion, the deep-hole pecking cycle has a parameter that controls the clearance amount between pecks. Also, the turning center multiple repetitive cycle for rough turning and boring (G71) has a parameter that controls how far the tool will retract (still feeding) between roughing passes.
3. Data entry
A parameter controls whether a value without a decimal point will be taken as a whole number or with fixed format. If set to a whole number, a coordinate value of 10 in the inch mode will be taken as 10 inches. In fixed-format mode, it will be taken as 0.0010 inch. This can affect program compatibility among machines and operator entries when making sizing adjustments. Another parameter sets the maximum size of a wear offset adjustment. Having this parameter set to 0.02 inch, for example, can help minimize operator entry mistakes.
4. Communications and file loading
Parameters control the methods by which programs can be transferred to and from the CNC as well as the device/media being used. Common choices include a flash drive, memory card, ethernet or serial port. Another parameter determines when the CNC will stop loading programs: at an end of program word (like M30) or the end-of-file delimiter (%).
5. Program protection
Parameters are available to keep specified programs from being modified, deleted and/or displayed. This lets you protect important programs, such as probing programs, sub-programs and custom macros.
6. User defined G and M codes
Parameters let you specify that a chosen G or M code (like G101 or M87) will execute pre-determined CNC programs. This is important when developing custom macros for canned-cycle applications. Another custom-macro-related parameter lets you control the behavior of single block when executing logic and arithmetic commands: skipping them or executing them one by one.
7. Inch-Metric conversion
A parameter controls what happens when you switch measurement system modes. With one choice, the cnc 3 axis engraving center simply moves the decimal point to the right or left (no true conversion). A value of 10.0000 inches becomes 100.000 millimeters. With the other, all values, including axis positions and offset settings, are converted. A value of 10.0000 inches becomes 254.000 millimeters.
Finding a parameter in question
Knowing (or suspecting) that a parameter affects a given issue is just the beginning of correcting the issue. You must be able to find the parameter in question. Most CNC manufacturers document related parameters in a group, but since there are so many of them, it still can be difficult to find the one that is related to your particular issue.
While you can get a parameter list and start foraging through them, a better way is to consult the documentation (programming manual, operation manual, etc.) that describes the feature that is troubling you. For the peck-drilling cycle parameters, for instance, reference the G73 and G83 descriptions. You will find descriptions of all related parameters.
Programming parameter changes
The most common way to change parameter settings is to do so manually, using the display screen and MDI panel keyboard. But you can program changes for program-related parameters. With the G73 peck drilling retract amount for example, it may be necessary to use a setting of 0.005 inch for one cutting tool in a program and 0.010 inch for another.
The wireline coring core barrel is a drilling method for drilling the core from the drill pipe without lifting the drill. It has the characteristics of high drilling efficiency, good rock core quality, long bit life and low labor intensity. In actual work, the environment in which the rope drill is used is relatively harsh. Q series wireline core barrel have the advantages of simple structure, less wearing parts and high core-taking rate. The correct use of Q series wireline core barrel can reduce costs and improve work efficiency.
Application range
(1) Geological conditions
NQ rope core drilling tools can be used to drill a variety of formations and work best in hard rock formations in grades 6-9. Under the current technical conditions, it is generally not advisable to drill l0~12 grade rock, especially the extremely hard rock with dense rock structure and fine particles without grinding. When drilling into the above rock, the drill bit is extremely easy to wear, the drilling efficiency is extremely low, and the superiority of the NQ wireline coring core barrel cannot be fully utilized.
(2) Drilling depth
NQ rope core drilling tools can be used in shallow holes (100 ~ 300 m) and deep holes. The deeper the drilling, the better the economic and technical effect. The maximum depth of the NQ wireline coring core barrel should be judged according to the strength of the drill rod.
(3) Bit life
The NQ rope is used for core drilling. If the drill bit used is short in life and the drill bit is often drilled during the drilling process, it is easy to lose the meaning of using the core to drill.
Use of NQ rope core drilling tools
1. Relevant technical data
(1) Drilling pressure. The NQ wireline core barrel is the bottom lip of the drill bit, which is larger than the bottom lip of the ordinary diamond drill bit (about l/4), and the required drilling pressure is increased by 25%.
(2) Speed. The rotational speed can be calculated according to the rounding speed of the ordinary diamond drill bit, but the drilling depth should be considered.
(3) Pump volume. Because the NQ wireline core barrel has a small annular gap and the bottom lip of the drill bit is large, the pump volume is calculated according to the consumption of the flushing liquid in the unit of the bottom lip of the drill bit, which is slightly larger than that of the ordinary diamond drilling.
2. Selection of rinse solution
Due to the small annulus between the NQ Wireline Coring Core Barrel and the hole wall, and the inner tube needs to be lowered through the center of the drill pipe column, water and lubricant should be used as the flushing liquid when the formation conditions permit. . Such as: polyacrylamide rinse, water glass rinse, etc. without solid phase rinse. When the drilled formation cannot use clean water as the rinsing liquid, the NQ rope core drilling still needs to use mud as the rinsing liquid. The characteristics of NQ Wireline Coring Core Barrel, the mud used in drilling should have the characteristics of low viscosity, low relative density, fast sanding, good fluidity and anti-mite performance.
The above is an introduction to the use of NQ Wireline Coring Core Barrel from PEERCHEER. If you need it, please contact us.
