Crushing and recycling equipment for waste corrugated boards

Abstract

The crushing and recycling equipment comprises a protection box and a processing box, two cover plates are arranged at the upper end of the protection box, an inner plate and an outer plate are connected to the two sides of the lower end of each cover plate, and a pretreatment mechanism is arranged between every two opposite inner plates; the processing box is located at the lower end of the protection box, a channel box is connected between the processing box and the protection box, a plurality of rotationally-installed smashing rollers are arranged at the upper end in the processing box, obliquely-installed screens are arranged at the lower ends of the smashing rollers, a material returning box is connected to one side of the processing box, a shaft rod is rotationally installed in the material returning box, and a spiral conveying paddle is installed on the shaft rod. And a conveying pipeline is connected between the upper end of the side wall of the return box and the channel box. The device is simple in structure and high in automation degree, manual crushing by workers is not needed, the crushing efficiency is improved, the injury possibility of the workers is reduced, repeated crushing is adopted, the crushing effect can be ensured, paper scraps and dust can be prevented from flying out, and the physical and psychological health of the workers is protected.

Description

technical field [0001] The invention mainly relates to the technical field of corrugated cardboard recycling, in particular to a crushing and recycling equipment for waste corrugated cardboard. Background technique [0002] Corrugated paper is a board-like object made of liner paper and corrugated paper. It is generally divided into two types: single corrugated board and double corrugated board. The invention and application of corrugated paper have a history of more than 100 years. , high strength, excellent printing adaptability, convenient storage and handling, etc., more than 80% of corrugated paper can be recycled, and corrugated paper can be used as food or digital product packaging, relatively environmentally friendly and widely used. [0003] In the process of corrugated paper recycling, the corrugated paper needs to be crushed to facilitate the reprocessing of the corrugated paper. When the corrugated paper is manually crushed, the crushing efficiency is low and the...

Problems solved by technology

[0003] In the process of recycling corrugated paper, it is necessary to crush the corrugated paper to facilitate the reprocessing of the corrugated paper. When manually crushing the corrugated cardboard, the crushing efficiency is low and the operator is easily injured. The traditional crushing equipment has a single crushing process and the crushing effect is low. Not ideal, and it is easy to generate a lot of paper dust, which affects the health of the staff
