Information
  •   Longitudinal uniformity automatic control feeding system
      The system sets the extruder to set the extrusion amount and the actual extrusion amount, and dynamically takes the value detection. The mathematical control model of the follow-up and decrement is used to set and adjust the method, and the motor speed is timed, and the dynamic uninterrupted adjustment is made. (ie, the principle of follow-up control), the amount of extrusion is constant. Since the constant torque characteristic of the traction motor is good (steady-state accuracy is 0.5%), the film has no change in the amount of extrusion and the traction speed during the bubble forming to the traction process, and is wound up in a non-elastic state with a small tension or a constant tension. Ensure accurate dimensions, stable physical properties and the proportion of raw materials between layers of a multi-layer machine. It also makes a small amount of precious raw materials accurately and controllable. Expanded the space used for high quality films in the engineering field or in a wider range of applications. Better meet the requirements of various types of high-speed printing, higher product value and increase economic efficiency.
