If you use this equipment often, can you be familiar with the vacuum pump time of vacuum packaging machine? Generally, we pack and observe the number of vacuum gauges as needed. For the actual packaging, if the packaging has high humidity or other special products, you need to adjust the number displayed by the vacuum gauge (up to 60 seconds).
The working principle is also very simple. The packaging bag should be placed in a vacuum chamber, and the mouth of the bag should be placed flat on a heating plate and covered with a pressure band. Adjust the heat-sealing temperature and time. The choice of heat-sealing temperature is Ⅰ and II. The thinner composite film should use I weak file. The thicker can choose the second strong file. It is sealed, does not melt and does not wrinkle. The amplitude should not be too large to prevent overheating and burning of Teflon and other mechanical parts.
The most important part of a vacuum packaging machine is the vacuum pump, which directly affects the quality of vacuum packaging. Therefore, when purchasing packaging equipment such as Shenzhen vacuum packaging machines, special attention should be paid to the quality of the vacuum pump. Second, in order to extend the service life of the equipment, we now use 304 steel vacuum packaging machines, and Shengfeng Electric uses all electric current * appliances to ensure that we can use a stable vacuum packaging machine.
Note: After two or three months of continuous operation of the vacuum packaging machine, you need to open the back cover, add lubricating oil to the sliding parts such as the slider, and develop a good habit of frequently checking decompression and filtering. Due to the frequent use of dust and other impurities, the normal operation of the machine will inevitably lead to the normal operation of the machine. Generally, there is water in the cup, or there are foreign objects in the silicone rubber belt and heating belt. Problems such as damage to high-temperature adhesive cloth have caused seal quality problems. Good maintenance habits allow us to find problems in a timely manner and control the occurrence of stalemate.
