Device for recovering discarded packaging paperboard

Abstract

The invention discloses a device for recovering a discarded packaging paperboard. The device comprises a supporting bottom plate, wherein supporting frames are symmetrically distributed on the supporting bottom plate; a crushing box is arranged between the supporting frames; the bottom of the crushing box is sleeved with a material receiving tank; the supporting bottom plate is provided with a supporting component; the supporting component is used for supporting the material receiving tank; a crushing roller is arranged in the crushing box; the crushing box is provided with a pretreatment box;the pretreatment box is provided with a material feed hopper; a driving rod is movably connected into the pretreatment box; one end of the driving rod is connected with a drive rod; one end of the drive rod is connected with a swinging rod; the swinging rod is connected with the pretreatment box through a rotating shaft; a fixing bracket is arranged in the pretreatment box; the fixing bracket isconnected with a driving shaft in a sliding manner; two ends of the driving shaft are both provided with mounting plates; crushing knife blades are uniformly distributed on the mounting plates; the driving shaft is provided with a drive plate; and spring rods are arranged between the drive plate and the fixing bracket. The device is novel in structure, automatic, high-efficiency and high in economic benefit; the recovery rate of the discarded paperboard is improved; and the waste is changed into the valuable.

Description

technical field [0001] The invention belongs to the technical field of cardboard recycling, in particular to a recycling device for waste packaging cardboard. Background technique [0002] In the production of cartons, it is necessary to cut the cardboard, which will generate a lot of waste cardboard. If these waste cardboards are not processed, they will take up a lot of space. If these waste cardboards are discarded at will, it will pollute the environment. Cardboard is usually made of wood, and the waste cardboard can be recycled to achieve the effect of secondary use. However, because these waste cardboards have different shapes, when recycling, the cardboard needs to be cut and shredded before recycling. [0003] However, the existing cardboard crushing device has the following defects in the use process: the cutting effect is poor, the fragments after cutting are large, which is not conducive to recycling, the recovery rate is low, and the waste of resources is serious...
