New Modification of Film Blowing Machine

The temperature control circuit of the film blowing machine adopts a thermostat plus a contactor. Due to the frequent high-current on and off state for a long time, the damage rate of the contactor is very high, and each thermostat can only control a period of temperature. As a result, many thermostats are scattered everywhere, which is very inconvenient to operate. The control circuit uses the relay interlocking method. The circuit is complicated, the maintenance is very difficult, and the reliability is very low. There are a series of other problems that cannot meet the needs of modern production.

The new type of film blowing machine uses PLC, touch screen and frequency converter for transformation. The new technology uses a temperature control module and a solid state relay to control the temperature, which solves the problem of parts damage caused by frequent and frequent switching on and off of large currents for a long time. The speed regulation of the frequency converter solves the problem of severe mechanical wear and energy consumption. The use of the touch screen helps the operator to intuitively understand the current state of the machine, and solves the problems of complex operation and difficulty in personnel training. The comprehensive application of the above technology has high reliability, can realize long-term maintenance-free equipment, and solve the problems of difficult maintenance and long maintenance downtime.

The new development makes the film blowing machine have greater advantages and higher benefits.
