Cutting device for shredder

Abstract

The invention discloses a cutting device for a shredder. The cutting device comprises a case; a motor is mounted inside the case; the output end of the motor is rotatably connected with a second rotating shaft; a fixed plate is fixed below the motor; the second rotating shaft is fixedly connected with a second belt pulley through the bearing of the fixed plate; the second belt pulley is rotatablyconnected with a first belt pulley through a belt; the upper end of the first belt pulley is fixedly provided with a first rotating shaft; the first rotating shaft passes through the fixed plate and is rotatably connected with a bearing on the case; the outer wall of the first rotating shaft is fixedly provided with cutting blades; the cutting blades and cutting knives fixed on the inner wall of the case are alternately arranged; and the left and right ends of the cutting blades are bonded with damping soundproofing felt. The cutting device of the invention solves the problem that the use of adouble-axis cutting knife increases power consumption, is not energy-saving and environment-friendly, generates noise and affects the work efficiency of people during operation through arrangement ofthe damping soundproof felt, the cutting blades, the cutting knives and the second rotating shaft.

Description

technical field [0001] The invention relates to the technical field of shredder cutting equipment, in particular to a cutting device for shredders. Background technique [0002] A shredder consists of a set of rotating blades, a comb and a drive motor. The paper is fed from the middle of the interlocking blades and is divided into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of paper shredded by a shredder knife after being processed by a shredder. According to the composition mode of paper shredder knife, existing paper shredding mode has: crushed shape, granular shape, segmental shape, foam shape, strip shape, silk shape etc. Today's paper shredders, in addition to processing paper, can also cut credit cards, CDs, etc. [0003] But the existing technology also has the following deficiencies: [0004] 1. Most shredders on the market use biaxial cutters for cutting, which increases power consumption and is...
