A packaging cardboard regeneration beating device

Abstract

The invention discloses a recycling and beating device for packing boards, which comprises a pulp chamber, a vibration platform and a paper shredding channel, wherein the paper shredding channel consists of a rolling inlet, a paper shredding chamber and a guide channel. The rolling inlet comprises an upper partition plate, a lower partition plate and a height regulator, and the lower partition plate is fixedly connected with the height regulator. The paper shredding chamber comprises a conveying roller and a rotating paper shredding roller, and the rotating paper shredding roller is arranged on the conveying roller. The pulp chamber comprises a beating barrel, a stirrer and a pulp liquid chamber, and the height of the pulp liquid chamber is larger than that of the beating barrel. The vibration platform comprises a base, a supporting spring and a vibration element. In the recycling and beating device, the paper shredding function is added before the traditional beating process, and theworking pressure of the stirrer is reduced, thus the beating effect can be better finished. Moreover, the vibration effect of the vibration platform accelerates the separation of the paper pulp and the pulp chamber in the beating process of the stirrer, which ensures the normal use of the stirrer, improves the production efficiency, separates the corrugated paper and the plastic paper, and lowersthe recycling cost of the paper board.

Description

technical field [0001] The invention belongs to the technical field of packaging paper recovery and regeneration, and in particular relates to a packaging cardboard regeneration beating device. Background technique [0002] Beating, also known as buckling, is a mechanical or fluid treatment of pulp fibers in water, subjecting the fibers to shear force, changing the shape of the fibers, and obtaining certain characteristics of the pulp to ensure that the paper meets the expected quality requirements. During the beating process, besides the shearing, kneading and carding effects of the machine parts, the cell wall of the fiber also undergoes displacement, deformation and rupture to absorb water and swell, resulting in fine fibrilization, which makes the pulp soft and plastic. The hydroxyl group in the cellulose molecular chain increases the chance of combining with the hydrogen chain, and improves the binding force between fibers.

AI Technical Summary

Problems solved by technology

[0003] As the most common raw material for carton manufacturing, corrugated cardboard has a high recycling effect. Usually, the cardboard is recycled and crushed and then mixed with water to form pulp. However, as a packaging box material, most of the cardboard surface will be bonded with a layer of plastic Paper, to meet the requirements of beautiful product packaging, the glued plastic paper does not have the regeneration function, directly forming pulp plastic paper will be mixed in the pulp to increase the production cost of recycling, and the agitator is in the process of long-term stirring, if the pulp If the flow rate is too low or too high, the rotation resistance of the agitator will be too large, and in severe cases, the agitator will be burned
