Fault of the bag-type packaging machine: the shrinking machine heats up slowly or cannot rise to a higher temperature
What is the reason for this situation for the bag packaging machine?

It is reported that the main power line of the heater goes through a magnetic switch and then to the electric heating tube. Therefore, when the shrinking machine heats up slowly or cannot rise to a higher temperature, first check whether the contacts of the magnetic switch are normal. Generally speaking, if the line does not pass through one of the phases, the above phenomenon will occur; if the magnetic switch is normal, check the meter again to see if the ohmic value of each phase is the same as that of the bag packaging machine; if all phases are connected But if the circuit or electric heating tube is still abnormal, the heater needs to be replaced.
