Description

The single-screw co-extrusion casting experimental line consists of two single-screw extruders (main units) and a casting machine (auxiliary unit). Designed for polymer material blending, modification, and new material R&D, this lab-scale production system enables advanced process optimization, quality control, and small-batch manufacturing of innovative polymer films.

Adopt Variable Frequency Motor

The single-screw extruder (main unit) features a robust design with five core components: a high-efficiency main motor, precision reduction gearbox, automated feeding system, advanced extrusion system, and intelligent electrical control system.

Temperature Control System

The temperature measurement and control system in this co-extrusion line is managed by a PLC controller, ensuring precision in multiple barrel heating zones. Each zone features thermocouples and solenoid valves for real-time regulation, while the main feed barrel functions as a non-controlled cooling zone, requiring no thermocouples or valves.

(1) Casting roller: Casting roller is powered by an independent motor, with adjustable rotation speed. Its surface is hard chrome-plated, and it features internal oil heating.
(2) Traction assembly: It consists of a steel roller and a rubber roller. The steel roller is driven by an independent motor and the rotation speed is adjustable. The surface of the rubber roller is coated with silicone and the material is soft. The rubber roller can be driven up and down by controlling the cylinder.
(3) Winding Assembly: The air shaft, driven by a torque motor, features adjustable rotation speed and an integrated air pressure system. The paper tube is mounted on the air shaft, which can be inflated with compressed gas.
(4) Roller clamping mechanism: The gap between the fixed and pressure rollers is adjusted by controlling the cylinder's activity through a PLC and touch screen. Pressing the clamping button causes the pressure roller to move upward, while pressing the release button makes it retract. When the rollers press together, the roller surface undergoes elastic deformation, pressing the thin strip between them. The strip moves due to friction, and its speed can be adjusted by changing the speed of the upper roller.
