Paper shredder poking wheel provided with positioning cam

Abstract

The invention discloses a paper shredder poking wheel provided with a positioning cam; and the paper shredder poking wheel is called a poking wheel (1) for short. A positioning wheel is arranged between two paper separation wheels of the poking wheel; the positioning wheel is a round gap cam provided with a standby edge and an avoiding edge; during applying, the device is mounted in a piling paperfeeder; the piling paper feeder is provided with a micro switch on the positioning wheel; when a paper shredder is stopped or standby, a trigger arm of the micro switch is pressed by the standby edgeof the positioning wheel, so that the micro switch is located in a communicating state; a microprocessor of the paper shredder controls a paper clamping slot of a paper poking wheel to stop in a starting position by a transmission shaft based on switch signals returned by the micro switch to wait for insertion of papers, so that the startup idling of the poking wheel is prevented; and the pilingpaper shredder achieves the purposes of prevention of the startup idling, improvement of the efficiency and convenient for users to use.

Description

technical field [0001] The invention relates to a distributing wheel of a paper shredder, in particular to a distributing wheel of a paper shredder provided with a positioning cam, which is used for sorting paper in the shredder. Background technique [0002] There are two types of shredders: single-insert and stacked. When the single-insert shredder is used, the waste documents are separated manually and sent to the shredder one by one for shredding; the stacked shredder has a Stacked paper feeder, when used, put waste documents in stacks into the stacked paper feeder, automatically select pages by the distribution wheel, and send them to the shredding roller knife one by one for crushing, that is, the distribution The wheel is a device used by the stacked paper feeder to pick up paper and send it to the shredding roller knife for crushing. [0003] The distribution wheel in the prior art is composed of a paper transfer wheel and a paper separation wheel. The paper transfe...

Problems solved by technology

[0003] The distribution wheel in the prior art is composed of a paper transfer wheel and a paper separation wheel. The paper transfer wheel is provided with convex fingers and paper clamping slots. Please refer to Chinese patent, a paper shredder distribution wheel with paper clamping slots 201610091391.1 ; In practical application, when the paper shredder is stopped or in standby after work, the position of the paper clamping groove of the paper transfer wheel is random, so that when the paper shredder is started every time, the distribution wheel needs to rotate a few circles to be able to Make the paper jamming slot hook to grab the paper, especially the old paper, and send it to the shredding roller knife for crushing, so that it affects the work efficiency and brings inconvenience to the user; therefore, the existing technology has low efficiency. , Inconvenient problems and deficiencies for users
