What are the common faults in heat shrink machines?

- May 24, 2019-

Compared with other packaging equipment, the heat shrinking machine is slightly more complicated in structure. Once there are some minor faults in this equipment, many people don't know how to solve it. Below, Fumao will introduce you to the common faults of the heat shrinkable film packaging machine. What are the troubleshooting methods?
Under normal circumstances, there are two situations in which the heat shrinking machine fails. One is that the hot air motor does not turn; the other is that the conveying net does not rotate; the third is that the shrinking chamber is not heated, that is, there is no heating phenomenon. Usually in these three cases, the troubleshooting method is as follows:

1. The hot air motor of the heat shrinking machine does not turn:

The hot air switch is damaged and replaced;

The motor is damaged and replaced.

2. The conveyor network of the heat shrinking machine does not turn:

The transfer switch is out of order and replaced;

The speed control board is broken and replaced;

The potentiometer is broken and replaced;

The conveyor motor is damaged and replaced;

The conveying mechanism is stuck and the fault is corrected after inspection.

3. The shrinkage chamber of the heat shrinking machine has no heating phenomenon:

Poor contact of the heating switch, replace the switch;

Indoor wire aging short circuit, replace the wire;

The electric heating line head is not connected or the electric heating tube is damaged;

The temperature control panel is damaged and replaced;

The potentiometer is broken and replaced.
