The machine is a special experimental equipment designed and manufactured by film casting & mdash; polyamide layer coating; the introduction of foreign similar product technology, using computer central control. Configuration PLC, integrated man-machine interface, operation and control of the whole machine, including: speed, tension control, online detection, online help, alarm processing and production parameter storage, etc., intuitive and convenient operation; multi-point drive and multi-stage tension Dynamic synchronization control. The unit realizes the tension taper (decrease) winding, ensures the winding quality and avoids crushing; adopts high-precision guide roller to ensure the product is free from scratches; the drying system is specially designed according to the drying mechanism —— hot air floating type Combined drying tunnel, thorough drying and high efficiency.
● The touch screen displays various operating parameters in real time, enabling the operator to synchronize the various parameters of the machine.
● Multi-stage tension control of the whole machine, servo motor drive, run by PLC control system, with stability unmatched by traditional control system.
● The rewinding and unwinding rolls are designed with a double station.
● The drying system is equipped with a closed drying oven, which has a secondary return air structure and is energy efficient.
● Each traction roller, pressure roller and system are controlled by pneumatic components with high automation.
● All kinds of guide rollers, gears, bearings, electrical components and pneumatic components are high-quality products (domestic brand products, some homemade).
● The number of oven groups can be increased according to customer requirements; the number of water tank groups.
The production process of the product consists of the following parts (required for the user):
Unwinding → A liquid immersion coating → volatilization & rarr; B liquid slit extrusion coating & rarr; drying evaporation → neutral → rinsing → protection → drying & rarr; It consists of a transmission system, an electrical control system, and a pneumatic system.
