Wholesale L Type Shrink Tunnel Heat Shrink Shrinking Packing Packaging Wrapping Machine

When the machine is used continuously for more than three months, the temperature resistant wires in the contraction chamber should be inspected and replaced according to their aging degree. During machine operation, the operator's palm and other parts are not allowed to come into contact with the operating parts of the machine, especially the extremely high temperature inside the contraction chamber, which can easily cause burns. After the packaging work is completed, the heating switch should be turned off first, and the conveyor motor and fan motor should continue to run for about 10 minutes before cutting off the entire power supply.

When the machine is specified to have a three-phase 380V power supply, the zero line must be input simultaneously, which is similar to other packaging equipment in the standard three-phase four wire system, such as vacuum packaging machines. Otherwise, the machine will not function properly and it is highly likely to burn out internal electrical components. The machine must be installed horizontally, otherwise it will shorten the service life of the electric heating tube. For machines with conveyor belts, their inclined installation will cause the conveyor belt to deviate from the center.

There are two ways to wrap items with flat film: single flat film and double flat film. The film should be wider than the object, using a double flat film, that is, wrapping it with two films on top and bottom. While the previous packaging is completed with sealing and cutting, the two films are sealed together. Then, the product is pushed into an upright film by machine or hand, and the sealing and cutting mechanism falls in place. The other side of the product is sealed and cut off. The product wrapped in the film shrinks after heat shrinkage, and the two ends of the packaging shrink to form an elliptical opening. When using a single flat film, First, unfold the flat film and feed the wrapped product towards the middle of the film to form a horseshoe shaped wrap, then heat seal and overlap the seal.

When using the shrink packaging machine, first place the products to be shrunk together. After the first pass, there will be film falling on the items to be packaged, but the packaging effect is not very good at this time. After the second pass, the effect will be very good. The plastic film packaging on the outside of food and beer has a very beautiful appearance. The heat shrink machine can also be paired with a disinfection and drying machine to form a complete set of equipment for wrapping bowls and chopsticks.
