The function of PLC controller in multi roller composite machine

   The compound liquid is injected into the compound groove of the multi roller composite machine me

  

  The compound liquid is injected into the compound groove of the multi roller composite machine mechanism, and the compound liquid is coated on the substrate through the transmission between the rollers. The coating thickness is determined by the rotation speed of the compound roller, which is controlled by the servo motor controlled by PLC controller through the servo driver.

Composite Machine

  It is difficult to measure the thickness of the compound directly, so the liquid level height of the compound liquid in the compound glue tank is measured by the liquid level sensor to obtain the glue consumption. The compound area can be measured by the compound width detection mechanism and the compound length detection mechanism.

  Through the calculation of PLC controller, the compound amount in a certain time can be obtained by dividing the compound area by the glue amount, and the compound amount calculated is compared with the reference value.

  When the deviation value of the two is too large, the alarm will be given immediately through the sound and light alarm. When the calculated compound amount is greater than the reference value, the PLC controller will automatically control the speed of the servo driver, that is, the speed of the compound roller will be increased to reduce the compound amount, otherwise, it will be decreased, so as to ensure the accuracy of compound amount and realize the automatic control of compound amount.
