Single-drive automatic paper feeding and shredding machine

Abstract

The invention discloses a single-drive automatic paper feeding and shredding machine which comprises a waste paper stacking box, a paper fetching device, a paper feeding wheel, a paper shredding drum, a shredded paper collecting box and a motor; the waste paper stacking box comprises a waste paper stacking plate, a pressure plate, a pressure sensor and a spring; the paper fetching device comprises a paper fetching idler wheel, a fixed rod and a paper fetching idler wheel support rod; the paper feeding wheel comprises an upper paper feeding wheel and a lower paper feeding wheel; the paper shredding drum comprises an upper paper shredding drum and a lower paper shredding drum; the paper fetching idler wheel, the lower paper feeding wheel and the lower paper shredding drum are axially provided with transmission wheels, and are connected through a chain; the motor is connected with the pressure sensor and the lower paper shredding drum; the upper paper shredding drum and the lower paper shredding drum are meshed through paper shredding drum transmission gears; the shredded paper collecting box is arranged below the paper shredding drum. According to the single-drive automatic paper feeding and shredding machine, when multiple pieces of waste paper exist, a user does not need to feed paper less for multiple times, and the waste paper is placed in the waste paper stacking plate, so that the paper can be automatically fed; the paper shredding efficiency is effectively prevented from being influenced by paper blockage; the single-drive automatic paper feeding and shredding machine is driven by using a single-drive element, so as to be more stable and efficient.

Description

technical field [0001] The invention belongs to the field of crushing machinery, and in particular relates to a high-efficiency paper shredder which can realize automatic paper feeding without manual paper feeding operation and is driven by a single driving element. Background technique [0002] Among the electrical appliances used in daily office life, paper shredders are essential office supplies. However, the user needs to be next to the paper shredder during use. Once a blockage occurs, it is convenient to clean up the blocked paper, and the paper inlet on the existing paper shredder is relatively small, requiring the user to feed a small amount of paper multiple times, wasting time. [0003] And once a certain driving element inside the shredder fails, if the paper is still being fed in order to find out in time, it is easy to block the shredder. Moreover, 95% of shredders on the market can only continue to work after 5 minutes of continuous shredding, and must res...

Problems solved by technology

However, the user needs to be next to the paper shredder when using it. Once a blockage occurs, it is easy to clean the blocked paper, and the paper inlet on the existing paper shredder is small, requiring the user to feed a small amount of paper many times, wasting time

[0003] And once a certain driving element inside the shredder fails, if the paper is still being fed in order to find out in time, it is easy to block the shredder

Moreover, 95% of the paper shredders on the market can only continue to work after 5 minutes of continuous shredding, and must rest for about 20 minutes.

If the parts in the shredder are of lower quality, longer rest periods are required; greatly reducing shredding efficiency
