Feeding device of plastic-wood extruder

Abstract

The invention belongs to the technical field of plastic-wood extruders and discloses a feeding device of a plastic-wood extruder. The feeding device comprises a processing box; a feeding hopper is arranged at the top of the processing box; the bottom of the feeding hopper is communicated with the top of a communication pipe; the bottom of the communication pipe is communicated with the top of theprocessing box; an L-shaped mounting plate is connected to the back face of the processing box; a second motor is mounted on the L-shaped mounting plate; and the output end of the second motor is connected with a fourth rotating rod through a first coupler. According to the feeding device of the invention, two extrusion rollers are adopted; the second motor is started to drive the two extrusion rollers to move in opposite directions; and therefore, a material falling on the two extrusion rollers is crushed initially. A first motor is started to drive a rotating plate to rotate; the rotating plate drives an extrusion ball to ascend and descend in the rotating process of the rotating plate; the extrusion ball extrudes the material in a flow pipe at a conical bottom in the descending processof the extrusion ball, so that the material can be further crushed. Therefore, the material can be crushed thoroughly, and product quality is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of wood plastic extruders, in particular to a feeding device for wood plastic extruders. Background technique [0002] Plastic wood panels have both the water resistance and corrosion resistance of plastics and the texture of wood. Its promotion and application can save a lot of natural wood and help protect the ecological environment. At the same time, because of the natural fiber composition, plastic wood panels have better resistance UV performance and lower thermal expansion and contraction performance, and easy to process like wood. The production process of wood-plastic panels is simple, and the raw materials used can use waste plastics, waste wood, agricultural and forestry straws and other plant fibers as the base material, without any additional harmful ingredients, and the production process is simple, fast forming, suitable for large-scale production. [0003] Existing plastic-wood extruders generally d...

AI Technical Summary

Problems solved by technology

[0003] Existing wood-plastic extruders generally do not process the material during feeding, resulting in a relatively large difference in the size of the material particles in the material, resulting in relatively poor quality of the produced product
