Problems solved by technology

The existing automatic shredders with separate paper feeding and shredding structures often have paper jams during the shredding process. Generally, there will be 2-5 paper jams per 1,000 sheets of paper, and it is required to stack the paper neatly before shredding. And manual removal of paper clips or staples on the paper can be effectively shredded by the shredder, which seriously affects the efficiency of automatic shredding

Embodiment 1

[0024] Place the two rows of shredding knives 4 horizontally with the ground, and place the paper release mechanism 2 horizontally with the ground. shape, a circle of cutting edge 41 is arranged on the outer edge of its circumference, and several gaps 42 are evenly arranged on the cutting edge 41 along the circumference. Withstand the lower end of the paper, the paper pressing mechanism 3 presses the paper downward, the motor 1 is started, and drives the two rows of shredding knives 4 to rotate relatively, and the paper is continuously brought into the shredding gap 7 by the shredding knives 4 for cutting.

Embodiment 2

[0026] The plane formed between the two rows of shredding cutters 4 is at an angle of 35° to the horizontal plane, and the paper releasing mechanism 2 is also at an angle of 35° to the horizontal plane. There are several protruding oblique knife edges 51 evenly arranged on the outer edge of the circumference, 500 sheets of paper are placed on the upper end of the paper platform 2, the shredding cutter 4 withstands the lower end of the paper, the paper pressing mechanism 3 presses the paper downward, and the motor 1 is started. The two rows of knives 4 are driven to rotate relatively, and the paper is continuously brought into the shredding gap 7 by the shredding knives 4 for cutting.

Embodiment 3

[0028] The plane formed between the two rows of shredding cutters 4 is placed perpendicular to the ground, and the paper release mechanism 2 is also perpendicular to the ground. The two rows of shredding cutters 4 are arranged in the middle of the right side of the paper discharge mechanism 2. 4 is a cylinder, and knurling protrusions 61 are arranged on the outer cylindrical surface of the paper shredding tool 4, and 1000 sheets of paper are vertically placed on the left end of the paper-discharging mechanism 2, and the paper-pressing mechanism 3 is perpendicular to the paper-discharging platform 2. The direction of shredding cutter 4 presses the paper in the left direction, the shredding cutter 4 bears against the right side of the paper, the motor 1 starts, and drives the two rows of shredding cutters 4 to rotate relative to each other, and the paper is continuously brought into the shredding gap 7 by the shredding cutter 4 Make a cut.

Abstract

Disclosed is a paper shredding mechanism, comprising paper shredding cutters (4), a paper placing mechanism (2), a paper compressing mechanism (3) and a driving electrical motor (1), wherein the paper shredding cutters (4) form two parallel rows, a shredded paper conveying gap (7) is provided between two paper shredding cutters (4), mounted at a position close to the centre at one side of the paper placing mechanism (2), the paper shredding cutters (4) are parallel to the plane of paper placement, with the top end being slightly higher than the plane of paper placement, and the paper compressing mechanism (3) is placed on the sheets of paper and the force of compression thereof on the sheets of paper is perpendicular to the plane of the paper shredding cutters (4). The paper shredding mechanism can begin to shred paper from the face of the sheets of paper in contact with the cutters, conveying the paper and shredding the paper simultaneously, changing the traditional paper shredding method which requires feeding paper at one end or conveys paper via a paper conveying mechanism to the cutter position and then shreds paper, thus significantly improving paper shredding efficiency, being fast, shredding a large volume of paper, and not jamming with paper.

Description

technical field [0001] The invention relates to the field of paper shredders, in particular to a paper shredding mechanism. Background technique [0002] A shredder consists of a set of rotating blades, a paper stopper 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. Shredded paper type refers to the shape of paper after it has been shredded by shredder knives after it has been processed by a shredder. According to the composition of the shredding cutter, the existing types of shredding are: granular, segmental, strip and so on. [0003] At present, the shredding method of the traditional paper shredder is to feed the paper through one end of the paper or the paper feeding mechanism (or wheel) to the cutter part and then shred the paper. Such a paper feeding method makes the shredder must be equipped with a paper feeding mechanism or Manual paper feeding...
