Waste paper cutting device capable of preventing cutter from accidentally injuring people after completion of cutting

Abstract

The invention relates to the technical field of pulpers, and discloses a waste paper cutting device capable of preventing a cutter from accidentally injuring people after completion of cutting; the waste paper cutting device comprises a workbench; the right side of the workbench is movably connected with a rotary knob, the left side of the rotary knob is fixedly connected with a threaded rod, andthe side, away from the rotary knob, of the threaded rod is movably connected with a rotary disc. According to the waste paper cutting device capable of preventing the cutter from accidentally injuring people after completion of cutting, the rotary knob is rotated, the threaded rod drives the rotary disc to move left and right at the moment, the rotation ratio between a driven disc and a driving disc is further changed, and the rotation speed of a cutting blade is changed at the moment; therefore, the effect that the cutting speed can be adjusted according to different materials is achieved. After cutting is completed, a third spring drives a second trapezoidal block to move leftwards, at the moment, the second trapezoidal block impacts a metal ball to trigger a stop button, a driving motor of the device stops working, and thus the effect of reducing the probability that a cutting knife accidentally hurts people during cutting is achieved.

Description

technical field [0001] The invention relates to the technical field of pulpers, in particular to a waste paper cutting device which prevents accidental injury of people by cutting knives after the cutting is completed. Background technique [0002] A pulper is a machine used for dissolution, hydrolysis and dispersion in the wet weaving and papermaking industries. It mainly relies on the mechanical action of the turntable, and also depends on the friction of the fibers to dissociate the fibers. During the production process, it is necessary to shred all hard and large paper such as broken paper and waste paper. [0003] When the existing cutting machine is cutting, the cutting piece is still rotating after the cutting is completed, and people may mistakenly touch the rotating cutting piece if they are not careful, resulting in personal injury, and the existing cutting machine The cutting speed cannot be adjusted according to different materials. When cutting hard objects at ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a waste paper cutting device that prevents the cutting knife from accidentally injuring people after the cutting is completed. It has the advantages of reducing the probability of accidentally hurting people by the cutting knife during cutting and can adjust the cutting speed according to different materials. , to solve the problem that when the existing cutting machine is cutting, the cutting piece is still rotating after the cutting is completed, and people may mistakenly touch the rotating cutting piece if they are not careful, resulting in personal injury, and the existing The cutting machine cannot adjust the cutting speed according to different materials. When cutting hard objects at a higher speed, the cutting piece may break, which not only affects the work efficiency, but also increases the production cost.
