Abstract

The invention provides an extrusion forming machine for a wood-plastic composite material. The extrusion forming machine is characterized in that: one end of a reduction gearbox is connected with a motor, and the other end is connected with a distribution gearbox; the motor is arranged below the distribution gearbox; the reduction ratio i of the reduction gearbox is 48.8; a preheating device is arranged on a feeding device; an anti-leakage groove is arranged on the outer surface of a screw edge of an extrusion screw rod, and a flow guide device is arranged in a runner hole cavity of a flow combined core. The extrusion forming machine belongs to special extrusion forming equipment for the wood-plastic composite material, which saves energy and floor area, improves the processing quality and efficiency, has stable product size and reduces abrasion of feeding conveying sections of a screw cylinder and the screw rod. The extrusion forming machine is applicable to the extrusion forming processing not only for the wood-plastic composite material which takes high-additive biomass plasticized raw materials as basic materials, but also for un-plasticized biomass raw materials which take PVC, PE, PP, ABS, PET and nylon as the basic materials.

Description

technical field [0001] The invention relates to extrusion molding processing equipment, in particular to an extrusion molding machine for wood-plastic composite materials. Background technique [0002] Wood-plastic composites are derived from modified plastics, but the processing requirements of wood-plastic composites are very different from plastics. However, existing wood-plastic composite material processing equipment, such as wood-plastic composite material extrusion molding machinery, basically adopts the structure of existing plastic processing machinery. Practice has proved that, as a new type of material with independent characteristics, the processing technology of wood-plastic composite materials is far more difficult than that of ordinary plastic products, and the production equipment is becoming more and more specialized and specialized. The main deficiencies of existing equipment are: [0003] The connection between the drive motor and the twin-screws of the ...
