First, the purchase of automatic vacuum packaging machine
Generally speaking, a good automatic vacuum packing machine can have the following points:
1. Material used in the appearance of automatic vacuum packing machine: now there are spray paint and stainless steel, stainless steel model is also different, now the vacuum machine can be used is 304 steel.
Automatic vacuum packing machine
2. The difference between the electrical appliances of the automatic vacuum packing machine, the good electrical components are not easy to break, and the bad electrical components are not the same.
3. The rationality of the link design of all parts of the automatic vacuum packing machine and the fine degree of installation have a certain influence on a good vacuum machine.
4. The quality of the vacuum pump has a certain influence on the use of different environment, different packaging, the quality of the vacuum pump will appear, mainly in the service life of the vacuum pump and the difference in the pumping rate.
Vacuum pump maintenance is also the main key link, a good vacuum pump is not maintained is also easy to break.
If you want to use a longer life of the automatic vacuum packing machine, you must pay attention to maintenance. The following points can be questioned:
1. Automatic vacuum packing machine should be used in the environment with temperature from -10℃ to 50℃, relative humidity not greater than 85%, no corrosive gas in the surrounding air, no dust and no explosive risk.
Like baler and shrink machine, this automatic vacuum packer is powered by three-phase 380V power supply.
2. Ensure that the vacuum pump works normally for the automatic vacuum packing machine, and the vacuum pump motor is not allowed to reverse.
Should often check the oil level, the normal oil level is 1/2-3/4 of the oil window (can not exceed), when there is water in the vacuum pump or the oil color becomes black, at this time should be replaced with new oil (generally continuous work for one or two months to replace once, with 1# vacuum gasoline or 30# gasoline, oil can also be).
3. Impurity filters should be dismantled and cleaned frequently (usually once every 1-2 months, such as packaging debris objects should shorten the cleaning time).
4. For continuous work for 2-3 months, the back cover should be opened to add lubricating oil to the sliding parts and switch touch blocks, and the connecting parts of the heating rod should be lubricated according to the use situation.
5. Frequently check the decompression, filtration and oil mist triplet 24 to ensure that there is oil in the oil mist and oil cup (sewing machine oil) and no water in the filter cup.
6. The heating strip and silica gel strip should be kept clean, and no foreign matter should be adhered to, so as not to affect the sealing quality.
7. On the heating rod, the two layers of sticky paste under the heating sheet play an insulating role. When there is damage, it should be replaced in time to avoid short circuit.
8. The working pressure of the vacuum packing machine has been set at 0.3Mpa, which is suitable. It should not be adjusted too much without special circumstances.
9, vacuum packaging machine in the process of handling is not allowed to tilt and impact, not to put down handling.
10. Vacuum packing machine must have reliable grounding device when it is installed.
11. It is strictly prohibited to put your hands under the heating rod to prevent injury. In case of emergency, cut off the power immediately
12. When working, first ventilate and then energize. When stopping, first cut off and then cut off.
