Manufacturing process of molded pulp packaging material

Abstract

The invention relates to a manufacturing process of a molded pulp packaging material. A packaging material manufacturing device is used. The packaging material manufacturing device comprises a pulpingpool and a pulping mechanism, wherein the pulping pool is arranged on the existing working ground; the pulping mechanism is arranged at the upper end of the pulping pool; the invention discloses themanufacturing process of the molded pulp packaging material based on the design concept of combining multiple crushing structures. The arranged pulping mechanism can perform dual treatment of crushingand grinding on raw materials as a whole, so that the crushing degree of the raw materials can be greatly improved, and the fineness degree of pulping slurry is further improved; and meanwhile, a arranged grinding group can achieve the purpose of improving the fibrosis degree of the raw materials in the formed slurry in a synchronous direction reciprocating rotation mode.

Description

technical field [0001] The invention relates to the field of pulp molding processing, in particular to a manufacturing process of pulp molding packaging materials. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material, and molds a certain shape of paper products on a molding machine with a special mold. The raw material for making pulp is waste paper, including cardboard, waste carton paper, Waste white edge paper, etc., have a wide range of sources. The production process of pulp molding includes basic processes such as raw material crushing and pulping, pulp mixing, adsorption molding, drying and shaping, shaping, and packaging. Pulp molding molded products are environmentally friendly. , can be recycled and reused, the volume is smaller than that of foamed plastics, can be overlapped, and the transportation is convenient. The proportion of pulp molding products in daily necessities and industrial cush...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the common crushing and pulping devices adopt a single and single-stage crushing structure, and the single crushing structure easily leads to a low degree of crushing of raw materials, and the degree of fibrosis of raw materials in the slurry is also low. At the same time, in the crushing structure The mixed liquid outside the working range, especially the mixed liquid near the raw material feeding port, has low fluidity, which affects the concentrated crushing of raw materials;

[0004] 2. In the case of no screening structure, the size of raw materials in the slurry tends to be inhomogeneous, which leads to low overall quality of the slurry and easily affects the subsequent pulping results. Under normal circumstances, the screening structure tends to accumulate more raw material fragments during long-term work, which reduces the screening effect itself.
