Shredder paper jam removing device

Abstract

The invention discloses a shredder paper jam removing device, which comprises a body with at least one input port; paper shredding blades equipped on the periphery of a rotating shaft inside the body for shredding paper inputted from the input port; a driving motor for driving the paper shredding blades; a transmission mechanism for transferring the driving force of the driving motor to the papershredding blades; a paper inlet channel equipped on the input port; a paper inducting sensor equipped on the paper inlet channel for inducting the paper existence; a driving motor sensor for inducting the driving motor rotation number or current; and a controlling part for judging whether a paper jam is located inside or outside on the basis of inducting results from the paper inducting sensor and the driving motor sensor and controlling the driving motor to automatically repeatedly rotate or reversely rotate according to the judging result. The invention can effectively remove the paper jam in the shredder and reduce the overload of the driving motor.

Description

technical field [0001] The invention relates to a paper shredder, in particular to a paper jam removal device for a paper shredder. Background technique [0002] A paper shredder is an office device that can quickly and safely shred confidential documents. Paper shredders in the prior art generally have a manual paper feeding function and an automatic paper feeding function. Among them, the automatic paper feeding function is to automatically feed the documents to be shredded, that is, to place a large number of documents to be shredded on the input port at one time, and the paper shredder will automatically put one or several papers into the paper according to the amount of shredding at one time. Inside the machine; such an automatic paper feeding function does not require the user to place the documents to be shredded on the input port in batches, but can place the documents to be shredded on the input port at one time, and continuously shred a large number of documents t...

AI Technical Summary

Problems solved by technology

[0003] However, when shredding a large number of documents in succession, paper jams often occur between the shredder blades

For this situation, the measures taken by the previous paper shredders to eliminate the paper jam phenomenon are: when the paper jam phenomenon is sensed, the motor is reversed. If the paper jam occurs outside the input port, manually remove the jammed paper. Continue to use; but if the paper jam occurs inside the machine, the operator cannot remove the jammed paper, and must ask after-sales service to remove the jammed paper. Before clearing, the shredder cannot be used, which is troublesome and delays work.

[0004] It can be seen that the above-mentioned existing paper shredder obviously still has inconvenience and defects in structure, and needs to be further improved urgently
