Sanding device for wood plastic plate

Abstract

The invention discloses a sanding device for a wood plastic plate. The sanding device comprises a frame body, a connecting plate, a wood plastic plate, a support beam, a sanding belt, a plate body, afirst slot, a second slot and a third slot, wherein a plurality of mounting slots are formed in the support beam; a magnetic rod is rotatably mounted in each of the mounting slots through a rotary shaft; a plurality of first magnetic blocks matched with the magnetic rods are mounted on the sanding belt through a supporting structure; a mounting rod is fixedly mounted on each of the first magneticblocks; and an ejection roller is rotatably mounted between the two corresponding mounting rods. The sanding device disclosed by the invention has the advantages that under cooperation of the magneticrods and the first magnetic blocks, propping action force is applied to the sanding belt when the ejection rollers are sanded, and the propping effect cannot be produced in no need of using; a movingoperation of the ejection rollers is simple, and syncrhonous operation of the plurality of ejection rollers can be realized through a first moving toothed bar; and meanwhile, through arrangement of apush block which can do reciprocating motion, thrust force can be applied to the lower end of a connecting piece, and thus, the situation that the lower end of the connecting piece is moved again into the first slot is ensured.

Description

technical field [0001] The invention relates to the technical field of wood-plastic boards, in particular to a sanding device for wood-plastic boards. Background technique [0002] During the manufacturing and processing of traditional wood-plastic panels, sanding is carried out by sanding machines, and then the burrs are artificially deburred after sanding, and the wood-plastic panels need to be artificially placed horizontally during sanding, which is cumbersome and time-consuming. strenuous. [0003] The Chinese authorized invention patent document with the patent number CN107186587B discloses a wood-plastic panel sanding device, which includes a frame with a sanding structure, a drive mechanism and a connecting piece, and a connecting plate connected to the frame. A side of the connecting plate away from the frame is provided with a first chute, a second chute and a chute, and the first chute and the second chute are parallel. [0004] Although the sanding device solve...

Problems solved by technology

[0005] 1. Use the elasticity of the spring to make the roller press against the sanding belt. Although it can make the sanding more fully, it also makes the sanding belt always in a tensioned state, which shortens the service life of the sanding belt to a certain extent.

[0006] 2. After the lower end of the connector enters the first chute, it is not easy to return to its original position. It can move down directly along the first chute, and it cannot be accurately ensured that it will move back into the second chute.
