Overload buffering mechanism for paper shredder

Abstract

The invention discloses an overload buffering mechanism for a paper shredder. The overload buffering mechanism for the paper shredder comprises a motor and a driving paper-shredding rotating shaft driven by the motor, wherein the driving paper-shredding rotating shaft is provided with a driving paper-shredding gear, a buffering block which is coaxial with the driving paper-shredding gear, a buffering gear sleeved outside the buffering block and a rolling element arranged between the buffering block and the buffering gear; the center of the buffering gear is provided with an accommodation hole limited by a first inner circumferential wall; the periphery of the buffering block forms a first outer circumferential wall which is provided with at least one buffering groove consisting of a bottom wall and side walls formed at both ends of the bottom wall; and the buffering block is accommodated in the accommodation hole of the buffering gear, and the rolling element is arranged in the buffering groove and closely clamped between the bottom wall and the first inner circumferential wall. The mechanism can effectively protect mechanical components and motors of paper shredders when the overload condition appears, so that faults such as gear slippage and / or motor burnout and the like are avoided; therefore, the overload protection of the paper shredders is further realized.

Description

【Technical field】 [0001] The invention relates to a paper shredder accessory, in particular to a paper shredder overload buffer mechanism capable of providing effective paper shredder overload protection. 【technical background】 [0002] Existing paper shredders cannot provide protection for its mechanical parts such as gears, shredder knives and motors in the event of overload. For example, when excessive paper is put into a shredder that exceeds the rated shredding capacity, abnormal phenomena such as machine jamming and gear grinding may occur due to too thick paper and excessive load, which may cause the machine to fail. The motor fails, such as burning the motor, causing serious deformation of mechanical parts, etc. 【Content of invention】 [0003] The purpose of the present invention is to provide a paper shredder overload buffer mechanism, which can effectively protect the mechanical parts and motors of the paper shredder in the event of overload, thereby preventing ...

Problems solved by technology

[0002] Existing shredders do not provide protection for their mechanical components such as gears, shredder knives and motors in the event of overload

For example, when excessive paper is put into a shredder that exceeds the rated shredding capacity, abnormal phenomena such as machine jamming and gear grinding may occur due to too thick paper and excessive load, which may cause the machine to fail. The motor fails, such as burning the motor, causing serious deformation of mechanical parts, etc.
