Description

Technical Field

[0001] The utility model relates to the technical field of high-strength corrugated base paper production, in particular to a device for recycling regenerated pulp to produce high-strength corrugated base paper. Background Technique

[0002] High-strength corrugated paper is a sheet material formed by bonding a facing paper and a corrugated high-strength corrugated paper processed by a corrugating roll. It is usually divided into two types: single high-strength corrugated cardboard and double high-strength corrugated cardboard. High-strength corrugated paper has good cardboard elasticity and compressive strength and is widely used in the packaging industry, especially in the production of cartons and transportation materials. The production of high-strength corrugated paper is similar to that of traditional paper and is made from pulp.

[0003] During the recycling pulping process of high-strength corrugated paper, a large amount of dust, sediment, and ink stains will adhere to the surface of the recycled high-strength corrugated paper, and impurities such as sewage may also be absorbed inside. However, the existing production devices cannot completely remove these impurities. Generally, they are manually cleaned before pulping, resulting in the inability to guarantee the production quality of high-strength corrugated base paper, high labor costs, and low efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for recycling regenerated pulp to produce high-strength corrugated base paper. Before pulping, the recycled high-strength corrugated paper is placed on a conveyor belt, and then under the action of an upper water pipe, a lower water pipe, and a brush, the upper and lower surfaces of the high-strength corrugated paper are respectively cleaned to remove dust, sediment, and ink stains. Then, the high-strength corrugated paper is squeezed to remove internal sewage and other impurities, greatly reducing impurities. Then, it is transported to a pulper for pulping, improving the pulp quality, thereby improving the quality of high-strength corrugated base paper. After secondary filtration of some high-strength corrugated paper scraps shed under a high-pressure nozzle, they are then injected into the pulper to reduce waste during the cleaning process and improve the recovery rate. Overall, automated production is adopted to reduce labor costs and improve production efficiency.
