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 knives 4 is placed perpendicular to the ground, and the paper release mechanism 2 is also perpendicular to the ground. 4 is a cylinder, and the outer cylindrical surface of the shredding tool 4 is provided with knurling protrusions 61, 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. Press the paper in the left direction, the shredding cutter 4 is 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

The invention relates to a paper shredding mechanism which comprises paper shredding tools, a paper placing mechanism, a paper pressing mechanism and a driving motor; the paper shredding tools are arranged in two parallel rows, and a shredded paper conveying notch is formed between the two rows of paper shredding tools, and is formed at the position at one side of the paper placing mechanism and close to the middle part; the paper shredding tools are in parallel to the plane in which paper is placed, and the top ends of the paper shredding tools are slightly higher than the plane in which the paper is placed; and the paper pressing mechanism is arranged on the paper, and the direction of force (of the paper pressing mechanism) pressing to the paper is vertical to the planes of the paper breaking tools. According to the paper shredding mechanism, the paper can be shredded from the sides in which the contact surfaces of the paper and the tools are positioned, and paper conveying and paper shredding are carried out at the same time, the traditional paper shredding mode that the paper enters from one end or the paper is conveyed to tool parts through the paper conveying mechanism (or wheels) and then are shredded is changed; the paper shredding efficiency is improved greatly; the rapid is fast; the paper shredding amount is high; and the paper is not clamped.

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...
