Description

Swing paper mechanism at the paper drop port of the shredder

technical field

The utility model relates to a paper shredder, in particular to a paper-pushing mechanism that makes a swing plate swing back and forth relative to the rotation of a cutter shaft, so that the shredded paper falling through the cutter shaft falls evenly on the waste paper tube, and The way of flattening is gradually stacked upwards, so as to increase the space for the waste paper drum to hold shredded paper, and improve the shortcomings of the mountain-shaped pile of shredded paper that prevents subsequent shredded paper from falling down smoothly and affects the overall operation of the shredder. .

Background technique

As we all know, the paper shredder used to shred paper works on the principle that a large number of cutting blades (cutting blades) and spacers (spacers) are inserted on the rotary shaft (rotary shafts), and the motor and gear set (motor and gear) are used to box) drives the two parallel and relatively rotating knife shafts to cut the paper into thin strips by shearing the passing paper. According to the different mechanical cutting modes, paper shredders are divided into two types: stripe-cut shredders and cross-cut shredders. The paper is cut into strips longitudinally on the cutter wheel, and the blade of the latter has more than one hook-shaped blade, and the blades are arranged in a spiral shape on the rotating cutter wheel, so that the paper is not only cut into strips longitudinally, but also horizontally. Cut into shredded pieces of paper.

Regardless of the above-mentioned straight shredder or crushing shredder, it is generally sold with a waste paper drum (basket or bin) for shredded paper; as mentioned above, the cutting tool of the shredder uses a motor And the gear device drives two parallel and relatively rotating knife shafts, using shear force to cut the passing paper into thin strips or fragments, and then drop down to the waste paper drum through the paper drop port at the bottom of the shredder Inside. As the amount of shredded paper increases, the shredded paper pieces will gradually accumulate into a mountain shape under the paper discharge port of the shredder, commonly known as "chip mountain". When the height of the paper mountain reaches near the paper-feeding opening of the shredder, it will not only hinder the subsequent shredded paper from falling down smoothly, but even the shredded paper will be drawn into the cutter shaft and entangled in the gap between the blades to form a "jam". ", affecting the overall operation of the shredder.

Experience shows that when the "paper mountain" is formed, the user only needs to spread the mountain-shaped pieces of paper to the surroundings with his hands, which can not only increase the space for the waste paper tube to hold the pieces of paper, but also avoid the above-mentioned problems. The "paper mountain" prevents the subsequent shredded paper from falling down smoothly, and even causes the shredded paper to be drawn into the cutter shaft and mixed in the gap between the blades to form "jam" and other problems.

Utility model content

The main purpose of this utility model is to provide a paper-pushing mechanism that makes the swinging plate swing back and forth relative to the rotation of the cutter shaft, so that the pieces of shredded paper falling through the cutter shaft evenly fall on the waste paper tube, and the flattened The method is gradually stacked upwards, so as to increase the space for the waste paper drum to hold shredded paper, and improve the shortcomings of the mountain-shaped pile of shredded paper that prevents the subsequent shredded paper from falling down smoothly and affects the overall operation of the shredder.

In order to achieve the above purpose, the utility model provides a paper shredder paper falling mouth swing paper mechanism, including: cutting tool assembly, composed of motor and transmission gear and other components; shredder casing, used to accommodate the above The cutting tool assembly; the waste paper tube, which is placed under the above-mentioned shredder casing to collect shredded paper; and the paper-pushing mechanism, which is arranged under the above-mentioned cutting tool assembly, and reciprocates to move the shredded paper by the cutting tool assembly The pieces of paper are evenly transferred to the waste paper bin for collection.

A paper shredder of the present utility model accommodates a cutting tool assembly including a motor and a transmission gear in a casing, and installs a waste paper tube for collecting shredded paper pieces under the cutting tool assembly; There is a swinging plate near the paper drop port of the shell, which is connected with the transmission shaft through the connecting rod, and a driven gear is provided at one end of the transmission shaft to receive the power rotation from the cutting tool assembly, so that when the transmission shaft rotates, through the connecting rod The rod drives the swing plate to move back and forth in a reciprocating manner. The pieces of shredded paper falling through the cutter shaft can evenly fall on the waste paper drum through the back and forth swing of the swing plate, and gradually pile up in a flattened manner, so as to increase the space for the waste paper drum to hold the shredded paper and improve the original The shredded paper piled up in a mountain shape prevents the subsequent shredded paper from falling down smoothly and affects the overall operation of the shredder.
