Protection device for paper shredder capable of preventing residues on outer wall of paper shredding wheel

Abstract

The invention discloses a paper shredder protection device capable of preventing residue on the outer wall of a paper shredding wheel in the technical field of paper shredders, and the paper shredder protection device comprises a paper shredder main body, the left and right sides of the top of the inner cavity of the paper shredder main body are symmetrically provided with residue-preventing paper shredding wheel protection mechanisms with the same structure; the anti-residue paper shredding wheel protection mechanism comprises paper shredding wheel pieces which are symmetrically and movably arranged on the left side and the right side of the top of an inner cavity of the paper shredder body, one end of each paper shredding wheel piece is connected with a clearing mechanism, and one end of each clearing mechanism is connected with a blowing piece. The anti-residue paper shredding wheel protection mechanism is arranged, when a paper shredding tooth piece moves to the outer wall of the driven roller from a transition arc-shaped convex part, under the action of a connecting spring, a tooth blade inwards enters a movable opening in the paper shredding roller, on one hand, paper shreds remaining on the tooth blade are pushed away from the tooth blade when the tooth blade moves, and on the other hand, the paper shredder is matched with a removing mechanism, so that the paper shredder is convenient to clean. And as the tooth blades at the positions are retracted inwards, the cleaning quality is higher, and the electrostatic eliminating bristles are prevented from being damaged due to the influence of the tooth blades.

Description

technical field [0001] The invention relates to the technical field of paper shredders, in particular to a protection device for shredders that prevents residues on the outer wall of a shredding wheel. Background technique [0002] As a common material in daily office, paper is usually discarded during its long-term use. This method leads to waste of resources and pollutes the environment. Especially in the office, in order to prevent the leakage of information on paper, it is usually used up directly Put in a shredder. [0003] Most of the existing paper shredders process the paper through two sets of shredding blades inside. At present, most of the existing shredding blades are located at the paper inlet of the main body of the shredder, and the paper is processed by the shredding blades. When processing, the paper is pierced through the tooth edge on the outer wall, and the shredded paper scraps generated during the piercing will remain on the tooth edge. With the rotati...

[0002] As a common material in daily office, paper is usually discarded during its long-term use. This method leads to waste of resources and pollutes the environment. Especially in the office, in order to prevent the leakage of information on paper, it is usually used up directly put in the shredder

[0003] Most of the existing paper shredders process the paper through two sets of shredding blades inside. At present, most of the existing shredding blades are located at the paper inlet of the main body of the shredder, and the paper is processed by the shredding blades. When processing, the paper is pierced through the tooth edge on the outer wall, and the shredded paper scraps generated during the piercing will remain on the tooth edge. With the rotation of the shredding blade group, the remaining shredded paper scraps on the tooth edge gradually increase. Then it is easy to cause paper jams, which will cause the motor of the shredder to temporarily fail. The existing brush bristles are used to contact with the shredder blade set when it rotates to brush off the remaining shredded paper on the outer wall tooth edge. However, in this way, on the one hand, the contact between the tooth edge and the bristles will cause damage to the bristles, which will not only easily cause damage to the inside of the shredder, but on the other hand, there will be a gap between the damaged bristles and the shredder blade group, and the remaining shredded paper cannot be removed. crumbs
