Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper crushing, in particular to a corrugated paper recycling and crushing device. Background Art

[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper with a waveform formed by a corrugating roll. It is commonly used in various industries and has a huge consumption. Therefore, a large amount of waste corrugated cardboard will be generated. In order to improve the recycling rate of resources, the waste corrugated cardboard is usually crushed and reprocessed to achieve the effect of secondary utilization.

[0003] Most of the existing crushing devices can only crush corrugated paper. The crushed paper scraps will be transported to the next pulping process by the operator. Since a large amount of dust will be generated after the corrugated paper is crushed, it will have a certain impact on the physical health of the workers. Moreover, the occupied volume of the paper scraps is relatively large. If directly transported, multiple transfers are required, and the separation of processes will increase the production cost. On the other hand, considering the characteristic that the paper scraps are easy to accumulate, when the existing crushing device crushes corrugated paper, due to excessive feeding, the paper scraps may accumulate at the discharge port, resulting in uneven feeding, sometimes more and sometimes less, leading to poor mixing effect of the pulp and possible phenomenon of paper scraps agglomeration.

[0004] Aiming at the technical problems existing in the prior art, the utility model provides a corrugated paper recycling and crushing device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a corrugated paper recycling and crushing device is proposed.

A reciprocating lead screw is rotatably connected in the installation cavity. A third transmission wheel is rotatably connected to the outer side wall of the crushing chamber directly below the second transmission wheel, and the third transmission wheel is fixedly connected to the reciprocating lead screw.

[0008] Preferably, a moving seat is threadedly connected to the reciprocating lead screw, a baffle is fixedly installed on the moving seat, and one end of the baffle penetrates through the side wall of the installation cavity and is located in the discharge hole.
