Introduction to temperature control of heat shrink packaging machine

Recently, some customers have reported that the temperature control operation is not good when using the heat shrink packaging machine, such as slow heating or simply unable to heat up. It is also a relatively common problem and relatively easy to solve. First of all, let's analyze the working principle of heating. The heater circuit used on the machine is the main power supply passing through a magnetic switch and then to the electric heating tube. Therefore, when the temperature cannot be heated up or the temperature rises slowly, you should check the magnetic absorption first. Check whether each connection point of the switch is normal. On the one hand, this problem may be that the line does not pass through it, and one phase, the above phenomenon will occur. If the magnetic switch is normal, you can check the meter again to see if the ohmic value of each phase is the same as that of the machine. On the other hand, it may be because of the short circuit. If all phases are connected but the circuit or electric heating tube is still abnormal, the heater needs to be replaced. Here is to let you know the working performance of the heat shrinkable film packaging machine, and then to understand the heating principle, find out the problem, analyze the problem, in order to be able to better and better solve all aspects of the problem for customers, but also to promote this With the understanding of technical knowledge, in the event of a problem, some relatively simple maintenance inspections can be carried out before the after-sales service arrives, so as to avoid unnecessary economic losses caused by the failure of the production line to operate normally.
