Efficient waste paper pulverizing device

Abstract

The invention relates to the field of paper making and particularly provides an efficient waste paper pulverizing device. The pulverizing device comprises a horizontally arranged support frame, wherein a pulverizing box is arranged at the top of the support frame, a paper feeding box is arranged at the top of the pulverizing box, a partition board is horizontally arranged at the connecting part ofthe pulverizing box and the paper feeding box, a feeding opening is arranged in the top of the paper feeding box, and a conveyer belt for conveying waste paper is correspondingly arranged at the position of the feeding opening; and a material guide frame is arranged on the bottom partition board of the paper feeding box below the feeding opening, and a through hole is correspondingly arranged inthe partition board at the bottom outer side of the material guide frame. The structural design is reasonable, the waste paper can be rapidly swallowed after being filled, the pulverizing efficiency is high, and the part of the pulverized waste paper of which the size is unqualified can be effectively secondarily or repeatedly pulverized, so that high waste paper pulverizing rate is ensured. At the same time, fly dust in the pulverizing process of the waste paper can be effectively inhibited, a great working environment is ensured, the structure is reliable and durable, manual operation and maintenance are facilitated, the practicability is high, and actual use conditions are met.

Description

[0002] In the waste paper recycling process, after the paper mill sorts the waste paper, the waste paper needs to be shredded in advance before putting the waste paper into the pulp pool to make pulp according to the process flow. The patent number in the prior art is CN201710074920. The invention patent of 1 discloses a high-efficiency waste paper collection device for environmental protection, which uses two rollers with blades to crush the waste paper, and at the same time drives the crank connecting rod structure pumping piston to spray air into the crushing box through a geared motor. The large waste paper scraps after the drum cutting are blown up again for cutting, but this invention patent has the following defects: it is not practical to use the geared motor to drive the crank connecting rod mechanism to drive the piston to spray air, and the working stroke of the crank connecting rod structure is relatively long in actual use. Long, poor structural durability, not suitable for recycling and crushing of waste products. At the same time, it is difficult to ensure the blowing effect of the air flow by using the piston jet, and the piston needs to be maintained and repaired. The air jet at the bottom of the box can only blow up the waste paper scraps that have not leaked down, but it is difficult to ensure that the two blade rollers can effectively crush the blown waste paper scraps for a second time

At present, when crushing waste paper products, most of them manually fill paper into the crushing device, but the efficiency of manual filling is low, and most of the crushing devices rely on the waste paper's own gravity to slide down for crushing, and the efficiency of the crushing device is not high. In view of the existing market conditions, there is a lack of a device that can efficiently crush waste paper, has strong practicability, and has a reliable and durable structure
