Description

Shredder mechanism

Field of practice

The present invention relates to the field of shredders, and more particularly to a shredder mechanism.

Background

The shredder consists of a set of rotating blades, a paper stopper and a drive motor. The paper is fed from the middle of the intertwined blades and is divided into a lot of small pieces of paper for confidentiality. The shredded paper type refers to the shape of the paper shredded by the shredder cutter after it has been processed by the shredder. According to the composition of the shredder cutter, the existing types of shredded paper are: granular, segment, strip, and the like.

At present, the shredder method of the conventional shredder is to pass the paper feed to the tool part through the paper feeding or paper feeding mechanism (or wheel) at one end of the paper, and the paper feeding method is such that the paper shredder must be provided with a paper feeding mechanism or Manual paper feeding increases the manufacturing cost of the shredder, has a complicated structure, and has a high failure rate.

With the increase of people's awareness of secrecy in modern society, various enterprises and institutions have increasingly demanded the confidentiality of documents, and the upgrading and upgrading of modern office equipment has made the function requirements of shredders more and more high. The existing automatic shredders with separate paper feeding and shredded papers often have paper jams during the shredding process. Generally, 2-5 jams per 1000 sheets of paper are required, and the papers need to be stacked neatly before being shredded. Manually remove the paper clip or staple on the paper to effectively shred the paper by the shredder, which seriously affects the efficiency of the automatic shredder.

Summary of the invention

The technical problem to be solved by the present invention is to provide a shredder mechanism for starting shredding of paper from the side where the paper is in contact with the cutter, and feeding and shredding the paper at the same time, changing the paper that must be fed at one end and passing through the paper to the cutter portion. The traditional shredded paper method greatly improves the efficiency of shredded paper, fast speed, large amount of shredded paper, and no paper jam.

The technical solution adopted by the present invention to solve the technical problem thereof is: providing a shredder mechanism, including a shredder cutter, a paper feeding mechanism, a paper pressing mechanism and a driving motor, wherein the shredder cutters are arranged in two rows in parallel, two broken A scrap paper gap is opened between the paper cutters, and is installed at a position of a side of the paper feeding mechanism, the paper cutter is parallel to the paper discharge plane, and the top end is slightly higher than the paper discharge plane, and the paper pressing mechanism is Placed on the paper and its force against the paper is perpendicular to the plane of the shredder. It acts as a better fit for the paper to make the cutting of the shredder more effective. The paper is pressed against the paper pressing mechanism. The shredder tool creates friction, and the paper moves with the cutter due to friction and is carried by the shredder tool into the gap of the shredded paper for cutting.

The cutter has a disk shape, and a circumferential edge is arranged with a ring edge, and the cutting edge is arranged with a plurality of notches along the circumference. The cutter has a disc shape, and a plurality of protruding oblique edges are arranged along the outer circumference of the circumference.

The cutter is in the form of a cylinder, and the outer cylindrical surface of the cutter is arranged with a knurling protrusion.

The scraped paper gap is disposed on a paper discharge mechanism between the two rows of shredder cutters.

The paper feeding mechanism is placed parallel to the ground or placed obliquely or perpendicular to the ground, and the angle between the paper discharge plane of the paper feeding mechanism and the horizontal plane is arbitrarily changed between 0 and 90 degrees.

When the paper feeding mechanism is placed perpendicular to the ground or diagonally, it can be placed in a larger amount of paper than when it is placed parallel to the ground. Beneficial effect

The invention relates to a shredder mechanism, which has a simple structure and high efficiency of shredded paper. Conventional shredders use a paper feed at one end, or a paper feed through a paper feed mechanism (or wheel) to the cutter. The present invention overcomes this inherent technical bias by using a method of picking paper from the bottom of the paper for shredding, feeding and shredding at the same time, eliminating the original paper feed mechanism. The invention does not have paper jam, the paper shredded paper has great power, and the paper clip and the staple are not needed to be removed, which saves labor, and the shredding speed is 2 to 3 times higher than that of the existing device, and is suitable for different security levels. Required shredded paper.
