WPC floor (foam board) efficient extrusion production line has a wide range of applications. It can not only produce WPC floor, but also produce PVC foam board, pvc wall board, PVC building formwork, etc. The production line is composed of the following parts: PS115-22 (PS130-22) parallel twin-screw extruder, clothes hanger flat die, setting template, refrigerator, cooling bracket, traction, cutting machine, plate lifting machine and other parts. Model: PS115-22+BF1500B； PS130-22+BF1900 Brand: RICHON The transmission system of extruder reducer is developed, designed, processed and manufactured by our company according to German technology, and obtained a patent (ZL2013 2 0052400.8). The gear has the requirements of high surface hardness and high core toughness. It adopts German ina and fag bearings, which have the advantages of high bearing capacity, large output torque, high torque coefficient, low noise, stable operation and long service life. Low energy consumption. Our reducer adopts four-stage speed change. The driving power of PS115-22 flat double extruder is 75kW and that of PS130-22 flat double extruder is 110KW, which saves 35% compared with the power distribution power of cone double extruder High production capacity. The parallel twin-screw extruder has stable operation, few faults, long service life of the screw, easy operation essentials for the operators, and other comprehensive factors, so that the operation time can be controlled and the product quality is stable. Moreover, the physical indexes of the plate are higher than those of the conical twin-screw extruder, and the output is 1.75 times that of the conical twin-screw extruder. PVC/WPC-PS115 floor (foam board) extrusion line meets CE certification requirements, and its electrical control part meets UL standards.
