How to Deal with Continuous Heating of External Vacuum Packaging Machine?

The heating time of the external vacuum packaging machine is controlled by the controller's time. However, if the controller fails, there will be continuous heating, which will cause fire and other faults. This is very dangerous, so how to deal with such potential safety hazards?

To solve this problem, we suggest installing a time relay at the front end of the controller. The function of this time relay is to control the heating time. When the vacuum packaging machine has reached the set time but has not been disconnected, the time relay will automatically disconnect the circuit and cut off the power supply of the machine, thus playing the role of protection.

Although this situation will not happen frequently, we should make corresponding preparations. At the same time, we remind you that vulnerable parts should be replaced in time if they are damaged, especially vulnerable parts such as heat insulation cloth, so as to avoid fire caused by direct contact of heating belt with products.
