PE wood plastic particle processing device

Abstract

The invention relates to the technical field of industry manufacturing, in particular to a PE wood plastic particle processing device. The PE wood plastic particle processing device comprises a material barrel and a screw rotationally arranged in the material barrel. The material barrel comprises a first material barrel body, a second material barrel body and a connecting part used for connectingthe first material barrel body with the second material barrel body. The screw correspondingly includes a first screw body and a second screw body, wherein the first screw body is provided with a highspiral blade, and the second screw body is provided with a low spiral blade. The first material barrel body is provided with a feeding hopper and an exhaust hole, the exhaust hole communicates with an exhaust pipe, and the exhaust pipe is arranged on the feeding hopper. The exterior of the second material barrel body is provided with a cooling water pipe, a water collecting box is further arranged below the cooling water pipe, a rotation shaft is rotationally connected in the water collecting box, the rotation shaft is provided with a wood board in a radial manner, and the rotation shaft is coaxially and fixedly connected with a rectangular prism. The water collecting box is further in sliding connection with a sliding rod. One end of the sliding rod is in sliding connection with the circumferential face of the rectangular prism. By adoption of the scheme, PE wood plastic particle extruded products are uniform in organization component, and the product inner stress is small.

Description

technical field [0001] The invention relates to the technical field of industrial manufacturing, in particular to a processing device for PE wood-plastic particles. Background technique [0002] PE wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, mixed with wood powder, rice husk, bamboo powder and other plant fibers to form new wood materials, and prepared by mixing and granulating. Composite material particles are raw materials for the production of plates or profiles, and are mainly used in building materials, furniture, logistics packaging and other industries. PE wood-plastic composite materials must be prepared into particles before they can be used. The processing equipment of PE wood-plastic composite materials generally includes three parts: feeding equipment, drying equipment and extruding granule equipment.

Problems solved by technology

[0003] Pay attention to the processing of PE wood-plastic composite materials: 1) During the feeding process, the wood powder structure is fluffy, and it is not easy to feed the extruder screw, especially when the wood powder contains a lot of water, it will often appear "bridging" And the "holding rod" phenomenon, two situations are prone to occur in the feeding process, one is that the instability of the feeding will lead to extrusion fluctuations, which in turn will lead to a decrease in the extrusion quality and output of the composite material, and the other is the interruption of feeding , it will prolong the residence time of the material in the barrel, cause the material to burn and change color, and affect the internal quality and appearance of the product; 2) During the processing, attention should be paid to the exhaust problem, and the quality of the extruded product of PE wood-plastic composite material is very large. To a certain extent, it is related to the exhaust effect, because the small molecule volatile substances and moisture contained in the wood powder can easily bring defects to the product, and the pre-treatment cannot completely remove them, so the exhaust system of the wood-plastic composite extruder More attention should be paid to the design of plastic extruders than ordinary plastic extruders, and multi-stage exhaust can be carried out if necessary
