How the plastic extruder production line works

Oct 08, 2019

Extrusion molding is a process in which a compound having a certain plasticity is continuously pressed out through a mouth shape under certain conditions to make it a product having a certain sectional shape.

During the forward movement of the rubber material, the viscosity and plasticity of the rubber compound have changed to some extent due to mechanical action and thermal action, and become a viscous fluid. According to the change of the rubber compound in the extrusion process, the working part of the screw is generally divided into three parts: the feeding section, the compression section and the extrusion section according to different functions.

1. The extrusion screw adopts the Japanese extrusion process optimization design, which can adapt to the processing of materials with high heat sensitivity, excellent fluidity and high melt viscosity. Under the premise of ensuring good plasticization, it can meet high-speed and stable output;

2. The high-pressure volumetric pipe die is used to make the machine head have larger melt pressure, improve the quality of the pipe and ensure the material is more smoothly extruded;

3. The main body of stainless steel vacuum cooling water tank is formed by SUS304 stainless steel bending; the water tank frame adopts spiral lifter device, which can be adjusted up and down, left and right, three-dimensional adjustment, easy to operate; high-quality liquid ring vacuum pump is used to provide stable vacuum negative pressure; equipped with stainless steel water storage tank and centrifugal The water pump can form a water circuit cycle with the external cold water supply;

4. The tractor adopts imported multi-layered wear-resistant material traction belt, high leveling precision roller traction drive, Swiss ABB AC frequency conversion controller, traction speed stepless speed regulation;

5. The cutting machine adopts low inertia aluminum alloy rotating knife arm structure with locking device, the cutting is smooth and smooth, the servo drive control system provides high-speed and high cutting action, and the man-machine interface can realize “continuous cutting, timing cutting, length cutting” Different cutting methods, the cutting length can be arbitrarily set, the number of cutting times is automatically counted, and the cutting requirements of products of various lengths are met.
