Abstract: In life, we often use vacuum sealing machines to seal bagged food. Various foods sealed by vacuum sealing machines can not only extend the shelf life at room temperature, but also have better effects if used in conjunction with a refrigerator. Better. But sometimes when using a vacuum packaging machine for sealing, we often encounter the problem that the machine cannot vacuum, or it only vacuums but does not seal. How should we solve it? Find out below. 1. What to do if the vacuum sealing machine does not vacuum
1. Long-term vacuum packaging, insufficient vacuum pump oil or poor oil quality, resulting in poor vacuuming. The solution is to replace the vacuum pump oil, and do not Long, endless hours of homework.
2. Pipe leakage is very common. Even if there is no pipe leakage, it is recommended to replace it after one year of use.
3. When there is a problem with the solenoid valve, do not solve it yourself. Ask a technician to help you deal with it.
4. The micro switch is not in place. There is a micro switch between the machine cover and the lower chamber. Just check and adjust the position.
5. The air release valve cannot be closed, causing air leakage. Check whether the air release valve is worn and whether there is any debris stuck.
6. The controller is broken, but the controller is a bit expensive. If it is within the warranty period, it is recommended that the manufacturer repair it.
7. If there is a problem with the vacuum pump, ask technicians to check it. Generally, this is difficult and cannot be solved by yourself.
8. Is the airbag leaking? If it is leaking, it must be replaced with a new one.
9. The distance between the two planes of the heating row and the silica gel strip in the vacuum chamber (the gap between the upper and lower heating rows is too small) causes the bag mouth to be clamped or partially squeezed during vacuuming, resulting in The air inside the bag is degassed.
10. When the vacuum packaging machine is running, pay attention to cleaning up dirty and foreign objects, and do not let dirty and foreign objects affect the normal use of the vacuum machine.
2. How to solve the problem when the vacuum sealing machine only vacuums but does not seal?
1. Check the bag
(1) Material problem
Bag There are several types: smooth bags, aluminum foil bags, gusset bags and textured bags. Only textured bags with 18 threads can be vacuum sealed normally, while aluminum foil bags and angled bags cannot be sealed if they exceed 18 threads.
(2) Placement problem
After eliminating the bag problem, we need to check again whether the bag is correctly placed in the vacuum tank. If not, we will try to reposition it. Pay attention to the correct position, and be careful not to press the machine onto the contents of the vacuum bag when placing it.
(3) Damage problem
The next step is to check whether there are air leaks in our bags. For example, if we use them to seal some sharp and prickly food, it may cause leaks. If the bag is punctured, the machine will continue to vacuum without sealing, then we need to change the bag.
2. Check the sponge strip
After eliminating the bag problem, we can check whether it is a sponge strip problem. When the machine vacuums and does not seal for a long time, we can press harder. On the machine panel, pay attention to whether the vacuum bag's vacuuming status changes, such as feeling that the vacuuming force becomes stronger and it can be sealed.
If the above operation cannot seal properly, we can remove the sponge strip and install it again, or directly replace it with a new sponge strip.
Notes:
1. When you are not using the machine, try not to close the cover frequently to avoid deformation caused by squeezing the sponge strip for a long time!
2. If you use the silicone strip model, you don’t have to worry. Compared with sponge strips, silicone strips are more durable and less prone to deformation.
