The transformation of temperature control circuit system of middle seal bag making machine

The transformation of temperature control circuit system of Middle Seal Bag Making Machine
It is understood that the temperature control circuit of some middle sealing Bag Making Machine adopts the mode of temperature controller and contactor, but because of the frequent use for a long time, the contactor here is easy to be damaged. In addition, each thermostat can only control one temperature, which makes the operation very inconvenient. In this case, it is necessary to reform the temperature control circuit of the machine.

Of course, the transformation of the temperature control circuit of the machine is not only to reduce the damage rate and convenient operation of the contactor, but also to improve the reliability of the control circuit, effectively reduce the mechanical wear and energy consumption. The transformation to achieve these goals is the application of PLC, touch screen and frequency converter.

After transformation, the temperature control module and solid-state relay are used to control the temperature of the Bag making machine, which solves the problem of parts damage caused by frequent and long-term large current on-off. The way of frequency converter speed regulation solves the problem of serious mechanical wear and energy consumption. The use of touch screen is more convenient for operation.

Through the comprehensive application of PLC, touch screen and frequency converter, combined with the actual needs of the machine to complete the control requirements. PLC temperature control module and solid-state relay are used to control the temperature of each section of bag making machine, PLC analog quantity module and frequency converter are used to control the speed of each motor; touch screen is used to complete the temperature setting and display, speed setting and display, fault setting and display, formula function realization, etc.

In a word, the comprehensive application of the above technology is reliable, which can realize the long-term maintenance free of the middle seal bag making machine, solve the problems of difficult maintenance and long maintenance downtime, and make greater benefits for users.
