Paper pulp material pulverizing device

Abstract

The invention discloses a paper pulp material pulverizing device which comprises a stone roll. A cylinder opening of a roll cylinder is upward, the middle of the roll cylinder is provided with a vertically arranged rotary spindle, the rotary spindle is connected with the stone roll through a flatly arranged stone roll shaft, the roll surface of the stone roll and the inner cylindrical bottom of the roll cylinder form rolling match, a cross rod is arranged on the rotary spindle, the middle of the cross rod is fixedly connected with the periphery of the rotary spindle, and inner and outer scraping plates are arranged below the cross rod and scrape and push a processed Xuan paper raw material to a rolling path of the stone roll in the process of rotating with the rotary spindle. The cross rod rotates by following the rotary spindle to drive the inner and outer scraping plates to move the processed Xuan paper raw material in the roll cylinder and scrape and push the processed Xuan paper raw material to the rolling path of the stone roll, the processed Xuan paper raw material can be uniformly and efficiently rolled in time, the fiber length of the processed Xuan paper raw material can be ensured, and the uniformity meets the quality requirement.

Description

technical field [0001] The invention belongs to the technical field of rice paper manufacture, in particular to a paper pulp crushing device. Background technique [0002] As a raw material for making rice paper, Liaocao is handmade paper made from rice straw in Shatian (Shatian rice straw in Jingxian County). Rice straw in other areas can also be used as raw material to make handmade paper, but it usually does not have traditional sense. The quality of rice paper) is used as raw material, which is processed by special traditional techniques to remove impurities such as lignin in rice straw for making rice paper. In the specific production process, the liaocao is chopped and dusted by a claw dust collector, and then wetted with water according to the humidity required by the process, and then transferred to the stone mill. The process requirements before crushing: a. The portion is 60-65%; b. Stacking time: ≥18 hours; c. The length of grass slices: 20-40mm. In the prior ar...

Problems solved by technology

In the prior art, the method of further crushing the above-mentioned liao grass is to use the traditional manual method of rolling the stone roller on the disc, which not only has low efficiency and high labor intensity, but also the liao grass cannot be evenly distributed during the rolling process. On the rolling path of the stone mill, the length and uniformity of the fibers of the rolled grass can not be guaranteed; moreover, during the rolling process of the stone mill, the grass is quickly pushed to the two ends of the stone mill, which is located at the edge of the mill. Burning grass is easy to fall from the grinding plate, but the burning grass in the plate cannot be rolled
