Features and advantages of vacuum food packaging machine

The vacuum food packaging machine is a new type of vacuum packaging machine, which automatically seals the packaging bag immediately after it is vacuumed to reach the ultimate vacuum. Inhibit the reproduction of microorganisms such as bacteria. Avoid mildew and corruption, and vacuumize some soft items to reduce the packaging volume, which is convenient for transportation and storage.

Main features of food vacuum packaging machine:

1. It is suitable for packaging small-size products and the packaging volume is not large.
2. The body is made of stainless steel, corrosion-resistant, rust-proof, and durable.
3. Advanced vacuum pump is used inside.
4. It has the characteristics of fast pumping rate, low operating noise and low operating cost.
5. The vacuum chamber cover is a plexiglass cover, which is transparent and can observe the packaging of the package.

What are the advantages of the vacuum food packaging machine:

1. It has the advantages of waterproof, moisture-proof, low failure rate and long service life.
2. The equipment is easy to clean, even if it is directly rinsed with water, there will be no electrical failure.
3. The whole machine is made of international standard 304 stainless steel for food, which has high strength and is not easy to be damaged.

 

How does the pillow packing machine achieve packaging?

pillow packing machine is a big category of packaging equipment, and it is the right-hand man of many manufacturers. It is a pillow packing machine, and its packaging capacity is very strong. The following briefly introduces the packaging capacity of the pillow packing machine.

pillow packing machines can be used not only for packaging of unmarked packaging materials, but also for packaging using reel materials with trademark patterns. In packaging production, due to factors such as the error between the positioning color standards printed on the packaging material, the stretching of the packaging material, and mechanical transmission, the predetermined sealing part of the packaging material may deviate from the correct position, causing errors.



In order to eliminate errors and achieve the purpose of correct sealing and cutting, automatic positioning needs to be considered in packaging design. Most of the problems are solved according to the positioning standards of packaging materials, and the design of the continuous photoelectric automatic positioning system is completed. According to the error compensation method, the continuous photoelectric positioning system can be divided into front and rear transmission systems, braking type and synchronous type.

pillow packing machine is used for positioning and cutting in packaging, which can prevent packaging film from sticking to the knife and avoid waste. Moreover, the transmission platform of the pillow packing machine is simple and reliable, which is not only convenient for packaging, but also easy for maintenance and cleaning. pillow packing machine is a kind of packaging machinery that keeps pace with the times, because its control system is realized with high-quality digital control software, which will not only facilitate the relevant personnel to adjust the functions of the pillow packing machine in the future, but also timely Improve the packaging technology and methods to make the packaging method of the pillow packing machine more advanced and unique.

Not only that, in the days to come, pillow packing machines will also achieve further practical and humanized development with the improvement of market demand and technological progress.

 

Precautions for ppr pipe during installation of pipe fittings.

What are the precautions for ppr pipe in the process of pipe fittings installation?

The normal use of ppr pipe fittings is inseparable from the correct and standardized installation. As a professional ppr pipe fitting manufacturer, ppr pipe manufacturers need to better regulate their own installation technology. First fix the wiring, and then slot into the ground. I think it’s better to let the plumber do it. After all, the plumber’s staff are more professional, so it won’t be great if the water pipes you connect to it leaks.

From the connection of PPR pipes: hot-melt connection. The melting temperature is 260 degrees. Your installation scale should refer to your design scale. This has to be designed according to your home improvement. Generally, PPR cannot be exposed to the surface. The first surface-mounted PPR will be deformed by gravity, and the second surface-mounted PPR will easily age. Third, if it is a white PPR, it can easily transmit light to form breeding bacteria. So it is recommended to bury it in secret. PPR water pipes can also be connected by hot-melt sockets. The pipes and pipe fittings are completely integrated, and the strength of the joints even exceeds the strength of the pipe body. As long as the construction is properly performed, it will pass the pressure test after completion, and the performance is extremely high.

Precautions for ppr pipe during installation of pipe fittings:

 1. The pressure test can be more than 30 minutes. If the site environment permits, the pressure test time can be longer.

 2. The purchase of ppr pipes and fittings must be guaranteed and must be operated by professionally trained technical workers.

 3. According to the horizontal, horizontal and vertical principle, a deep groove larger than the diameter of the water pipe should be grooved on the basic floor of the room, and then ppr pipe fittings should be laid, followed by sequential hot-melt connection. The process flow is very important.

4. After all ppr pipe fittings are fused together with hot melt technology, the necessary pressure strength test is carried out.

 5. The hot-melt technology is finalized after cooling. It is not that the longer the time, the better. Long-term pressure will damage the water pipe. When it is ensured that there is no leakage of water, then landfill is carried out.

Special attention should be paid to the appearance of ppr pipe welding, and non-destructive testing can only be carried out after the appearance inspection is qualified. Radiographic flaw detection shall be carried out on pipe welds that cross rivers, reservoirs, roads, railways, underground pipelines, cables, and optical cables, welds between straight pipes and elbows, and joints after pressure test.
