I. Selection of automatic vacuum packaging machine
Generally speaking, a good automatic vacuum packaging machine can have the following points:
1. Materials used for the appearance of the automatic laser marking machine: there are different types of stainless steel and spray-painted stainless steel, and the models of stainless steel are also different. Now the vacuum machine can use 304 steel.
2. The difference in electrical appliances of automatic vacuum packaging machine, good electrical components are not easy to bad, bad electrical components are not the same.
3. The rationality of the link design of each part of the automatic vacuum packaging machine and the degree of precision of installation have a certain impact on a good vacuum machine.
4. The quality of the vacuum pump of the automatic vacuum packaging machine has a certain impact. The quality of the vacuum pump will be reflected in the difference of the operating environment and packaging materials, mainly in the service life of the vacuum pump and the difference in the extraction rate.Vacuum pump maintenance is the main key link, A good vacuum pump is easily broken without maintenance.
If you want the full automatic vacuum packaging machine to have a longer service life, you must pay attention to the maintenance, you can question the following points:
1, Automatic vacuum packaging machine should be in temperature - 10 ℃, 50 ℃, relative humidity is not more than 85%,no corrosive gas in the surrounding air, no dust, no explosive danger in the environment.Like packing machine and shrinking machine, this automatic drink mixing system is powered by 380V three-phase power supply.
2, For the full automatic vacuum packaging machine to ensure that the vacuum pump work normally, vacuum pump motor is not allowed to reverse.Oil level should be checked frequently,, the normal oil level is 1/2 to 3/4 of the oil window (not more than), when there is water in the vacuum pump or oil color becomes black, at this time should be replaced with new oil (generally work for one or two months, with 1# vacuum gasoline or 30# gasoline, oil can also).
3. The impurities filter should be removed and washed frequently (generally, it should be cleaned once every 1-2 months; for example, the cleaning time of packaging debris should be shortened).
4. Open the back cover and add lubricating oil to 30 pairs of sliding parts and switch blocks after 2-3 months of continuous operation, and add lubricating oil to each connection activity on the heating rod according to the use situation.
5. Check the pressure reduction, filtration and oil mist triple connectors 24 frequently to ensure that there is oil (sewing machine oil) in the oil mist and oil cup and there is no water in the filter cup.
6. The heating strip and silicone strip shall be kept clean, and no foreign matter shall be adhered, so as not to affect the sealing quality.
7. The two layers of adhesive paste on the heating rod and under the heating sheet are insulated. In case of any damage, the adhesive paste should be replaced in time to avoid short circuit.
8. The working pressure of the vacuum packaging machine has been set to 0.3mpa, which is suitable for the user's self-provided working air source and inflation air source. Do not adjust it too much without special circumstances.
9, The vacuum packaging machine in the handling process is not allowed to tilt and impact, not to put down the handling.
10. The vacuum packaging machine must be installed with reliable grounding device.
11. Do not put your hands under the heating rod in case of injury. Cut off the power in case of emergency.
12, when the work of ventilation and then power, shut down the power and then cut off.
