A kind of pulp molding packaging material manufacturing process

Abstract

The invention relates to a manufacturing process of pulp molding packaging materials, which uses a packaging material manufacturing device, the packaging material manufacturing device includes a beating tank and a beating mechanism, the beating tank is installed on the existing working ground, the beating tank The upper end of the beating mechanism is provided with a pulp molding packaging material manufacturing device based on the design concept of combining multiple crushing structures in the present invention. The beating mechanism can be used to crush and grind the raw materials as a whole, so that the crushing of the raw materials can be greatly improved. The degree of beating can be improved, and the fineness of the beating slurry can be improved. At the same time, the grinding group can use the reciprocating movement in the synchronous direction to achieve the purpose of improving the degree of fiberization of the raw materials in the forming slurry.

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.
