In the packaging industry, the general bottled equipment is completed by a vacuum capping machine. If the bag packaging equipment needs to be vacuumed, it is generally completed by a vacuum packaging machine. Vacuum packaging machines and vacuum capping machines are commonly used packaging equipment in the packaging industry. We have already talked a lot about the maintenance of vacuum capping machines. Today we are talking about how to maintain the vacuum packaging machine.
1. When the vacuum pump is running, the oil level should be 3/4 of the oil window height. If it is lower than 1/2 the oil window height, the high-speed vacuum pump oil should be filled in time. If the oil level is too high or too low, the vacuum pump The motor causes disadvantages. Please refer to the operation instructions of the vacuum pump for specific methods.
2. The machine should be placed horizontally, the environment should be well ventilated, and there should be no corrosive gas or large dust around.
3. The machine must be equipped with a grounding protection line, and always check whether the connection point is in good contact to ensure personal safety.
4. The heating time and heating temperature must be set at a suitable position before the machine works, and the principle of from low to high must be mastered. The heat sealing time and temperature must not be set too long or high at once to avoid burning the electric heating components or Polytetrafluoroethylene sealing varnished cloth.
5. When the upper cover is pressed down, the vacuum pump starts to work. At this time, if the upper cover has not been sucked in place, the upper cover should be pressed down by hand (except for pneumatic type).
6. When the machine is working, it emits abnormal noise and the pointer of the vacuum gauge does not move, indicating that the vacuum pump may be running in the wrong direction. The phase of the three-phase power supply may be inconsistent with the factory phase. It should be shut down immediately, otherwise the vacuum pump will be easily damaged. At this time, only need to exchange any two of the three-phase power sources (the single-phase power source does not have this phenomenon).
7. Frequently check whether there is any foreign matter on the surface of the PTFE varnished cloth of the sealing part and whether it is flat to ensure the quality of the sealing. If damaged, replace it in time.
8. Check whether the screws in each part of the machine are loose, and whether the vacuum chamber moves flexibly from side to side. The movable parts and oil holes should be filled with proper amount of lubricating oil.
9. When the machine is working in an emergency, press the emergency stop button and the cover can be opened by itself.
10. After the machine is finished, the main power supply should be cut off.
