What are the common faults of plastic hot forming machines? How to avoid these malfunctions of plastic hot forming machine? The cup making machine is used to manufacture disposable plastic cups and other equipment. During the normal operation of the cup making machine, there will be some failures. To analyze the failure of cup making machine, so as to solve the problem faster and reduce the loss.
Fault 1, temperature controller display is not normal
The possible reason is that the temperature line is loose or the temperature controller is damaged, which causes the temperature to jump constantly. It may also be that the corresponding air switch after the chassis tripped or the ammeter line was burned or the heating line was broken or the fixed relay was damaged or the thermostat was damaged, resulting in the data temperature could not reach the set temperature, and the temperature was decreasing downward.
Fault 2. The oil pump does not start
The possible reason is that the oil pump line is loose, the oil pump relay is burnt out, or the oil pump is burnt out.
Fault three, pull the piece drag chain
Possible cause is worn chain fastener.
Solution: remove the chain fixing piece and weld the worn place completely or pad the lower gasket into oblique upward direction.
Fault four, do not drop the cup
Possible cause is a damaged blade or a loose proximity switch. Solution: a certain thickness of sheet pad under the lower die knife edge.
Trouble five, cup concave cup bottom
Possible reasons ① the positioning column of the lower die is loose, ② it may also be because the temperature of the die is too high. Solution: ① refix the positioning column, ② reduce the mold temperature.
Trouble 6. The bottom of the cup is too soft
Possible reasons ① the intake switch is loose and runs to the front of the stretch switch, ② it may also be because the fastening screw of the stretch arm is loose, leading to the drawdown of the head is too low. Solution: (1) tighten the intake switch, (2) tighten the stretch arm screw.
Fault seven, the cup body is too soft
Possible reasons: (1) the fastening screw of the stretching arm is loose, leading to too low drawing head, (2) it may also be because the mold temperature or set temperature is too high. Solution: (1) tighten the stretch arm screw, (2) lower the setting temperature or lower the mold temperature.
Through the introduction of the above plastic hot forming machine manufacturers, we should know how to refuse the plastic hot forming machine failure.
