There are many kinds of vacuum packaging machines, such as single chamber vacuum packaging machine, double chamber vacuum packaging machine, desktop vacuum packaging machine, vertical vacuum packaging machine and external vacuum packaging machine. The following is a brief introduction of one of its single chamber vacuum packaging machine. Some points should be paid attention to when replacing the heating strip. The single chamber vacuum packaging machine is a widely used packaging equipment, which mainly exhausts the air in the packaging bag and forms a low vacuum. Then the packaging is sealed and packaged. Because of the high vacuum in the bag, there is not much space Gas residue can effectively inhibit the growth and propagation of many aerobic bacteria and other microorganisms, which can also ensure that the products will not be oxidized or moldy during the transportation and storage process, and for some products with soft texture, after packaging with a real empty packaging machine, the volume after packaging can be greatly reduced, so that it is more To facilitate the transportation and storage of products.
As a necessary part of the vacuum packaging machine, the heating strip should be paid attention to. Although the replacement of the heating strip is relatively simple, we also need to pay attention to some matters:
1. Loosen the fixing card of the vacuum packaging machine, then take off the isolation cloth, untie the heating wire, then fix the screw and pull out the heating rod, then take off the heating rod.
2. Remove the broken heating piece, then remove the oxide layer of the fixed terminal of the heating wire, rotate the groove at one end of the new heating piece for one circle, and fix it on the insulating fixed block, and fix the other end on the other fixed block, and then tighten the heating piece.
3. If the adhesive tape is damaged, it should also be replaced. A total of two layers can be pasted.
And we also need to pay attention to the characteristics of the single chamber vacuum packaging machine: the unique electric heating arrangement is adopted, and the material in and out mode is forward and right, and the energy-saving design is also taken into account, which can effectively save energy, the whole equipment body is small, and the space occupied is very small; some key parts are imported original spare parts, so that The operation stability and reliability of the equipment are improved.
