China Cheap 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.
