WPC raw material mixing mechanism

Abstract

The invention discloses a plastic-wood raw material stirring mechanism which comprises a stirrer body. A raw material inlet is formed in the top of the stirrer body. A raw material outlet is formed in the lower part of the stirrer body. The plastic-wood raw material stirring mechanism further comprises a top plate, a plurality of hoppers, a seal ring, a filter screen, a first buffer net and a second ring. The top plate is fixed on a frame of the stirrer body and is positioned above the stirrer body. A plurality of branched inlets are formed in the top plate. The hoppers are fixed above the top plate. The outlets of the hoppers are in butt joint with the branched inlets. The lower edge of the seal ring is in contact with a stirring ring of the stirrer body. The top of the filter screen is fixed with the bottom surface of the top plate. The bottom of the filter screen is fixed with a first ring. The first ring is inserted in the seal ring, and is in contact with the seal ring. The outer ring of the first buffer net is fixed with the first ring. Plastic-wood raw materials can penetrate through the meshes of the first buffer net conveniently. The second ring is fixed on the first buffer net. The vertical direction of the second ring is aligned with the branched inlet. The plastic-wood raw material stirring mechanism has the beneficial effects that operation and maintenance are convenient, different raw materials can be poured in a stirrer within the same time, the working efficiency is improved, and the dust flying possibility is reduced.

Description

technical field [0001] The invention relates to a mixing and batching equipment for plastic-wood processing, in particular to a mixing and batching equipment for plastic-wood processing with dust-proof effect. Background technique [0002] Wood-plastic decorative material is a new type of green ecological environmental protection product made of waste plastic (RECYCLED PLASTIC), high-density polyethylene (HDPE) and plant fibers (bamboo powder, wood powder, etc.) through special treatment. Decorative materials not only have the characteristics of natural wood, but also can provide a variety of color options according to customer needs. At the same time, they also have the characteristics of no decay, no change, insect resistance, good fire performance, no cracks, easy installation, and no maintenance. The products are mainly suitable for outdoor balconies, walkways, railings, steps, fences, outdoor tables and chairs, flower stands, tree pools, etc., and can also be used in in...

AI Technical Summary

Problems solved by technology

[0003] In the process of wood-plastic processing, it is necessary to put plastic powder, wood powder, talc powder and additives in different proportions in the mixer and mix evenly, and then extrude at high temperature to granulate. In the prior art, the raw materials poured into the mixer are all the same It takes a lot of time to pour one bag after another, which greatly reduces the utilization rate of the mixer. In addition, every time it is poured, dust will fly, which seriously affects the health of the operators and wastes raw materials.
