GMS controller for plasticized product equipment—Blowing machine

Solve the problem of uneven thickness of finished film

1、abstract

    Winpark has developed the automatic GSM controller, this controller realizes the automatic control the weight of film blowing machine. It’s control the traction speed by collecting the flow rate of the raw material, then get the weight of the blown film. GSM controller effectively solve the problem of uneven thickness of finished products, which problem is due to the actual bulk density of raw material is unstable, the flow rate of raw material is uneven during the production process. The temperature difference of day and night, the grid voltage fluctuations and filter blockage are also the causes. GSM controller improved the production quality and production efficiency.

2、application background

  以挤出机为例，主控单元温度控制采用采集模块，经PCU运算，最后用输出点控制的方式，温控效果不稳定会导致生产过程中出现成品膜厚度不匀等现象。

Specific to an extruding machine using PLC as the main control unit. This extruding machine controls the acquisition module by temperature, then operated by the PCU, finally, it operates by the mode of output point control. This leads to inaccurate temperature control, and the cost is high.
