Packing paperboard regeneration efficient pulping device

Abstract

A packaging paperboard regeneration efficient pulping device comprises a closed tank body, a coaxial main shaft is rotationally installed in the tank body, a motor is fixedly installed on the top face of the tank body, an output shaft of the motor is fixedly connected with the upper end of the main shaft, a plurality of first rotating shafts are connected to the two sides of the periphery of the main shaft through torsion springs, and each first rotating shaft is fixedly connected with a first blade. A plurality of sliding sleeves are sleeved on the periphery of the main shaft, the sliding sleeves can only vertically slide on the periphery of the main shaft, and second rotating shafts are fixedly mounted on the front and rear sides of the top surfaces of the sliding sleeves respectively. The feeding state and the pulping state can be freely switched only by changing the running direction of the motor, on one hand, the soaking speed of paperboards in the feeding stage is increased, the paperboards are prevented from being stacked on the water surface in a large amount, on the other hand, the service life of the rotating blades is prolonged through reasonable division of labor of knife back stirring and knife edge pulping, The packaging paperboard regeneration efficient pulping device is suitable for being popularized as a novel beating machine for paperboard recovery.

Description

technical field [0001] The invention belongs to the field of packaging cardboard regeneration and recovery, in particular to a packaging cardboard recycling high-efficiency beating device. Background technique [0002] The recycling of packaging cardboard requires crushing and beating first, and then further processing of the stirred pulp. When the cardboard is just put into the beater, it takes a certain time for the cardboard to absorb water, and a large amount of cardboard will be stacked and floated on the water surface of the beater , workers need to wait for this batch of cardboard to be completely dissolved, or use tools to completely press the cardboard into the water before feeding the next batch; in addition, in order to improve the crushing efficiency, the beater will have many sharp rotating blades inside, but it has just been The undissolved paper in the water is relatively hard, and the blade of the rotating blade will continuously collide with the undissolved ...

[0002] The recycling of packaging cardboard requires crushing and beating first, and then further processing of the stirred pulp. When the cardboard is just put into the beater, it takes a certain time for the cardboard to absorb water, and a large amount of cardboard will be stacked and floated on the water surface of the beater , workers need to wait for this batch of cardboard to be completely dissolved, or use tools to completely press the cardboard into the water before feeding the next batch; in addition, in order to improve the crushing efficiency, the beater will have many sharp rotating blades inside, but it has just been The paper thrown into the water has not yet dissolved and its texture is relatively hard. The blade of the rotating blade will continuously collide with the undissolved cardboard and cut it, which will obviously shorten the service life of the blade.
