Description

Gland for paper shredder

Technical Field

The invention relates to the technical field of paper shredders, in particular to a gland for a paper shredder.

Background

The shredder is a common office equipment, which is widely used, and can be used for shredding paper, compact discs and the like to prevent important information from leaking.

Currently, there is a market for an automatic paper feeding shredder, which comprises: a shell, set up the shredded paper core in the shell, set up in shredded paper core top and be arranged in inhaling and conveying the material feeding unit in the shredded paper core with the paper, set up on the shell and can open lift the lid and install the collecting vessel in shredded paper core below, material feeding unit includes: the paper feeding device comprises a paper placing platform arranged above the paper shredder core and paper feeding rollers arranged on the paper placing platform in pairs, wherein a paper feeding opening used for clamping paper and conveying the paper to the paper shredder core is formed between the paper feeding rollers.

When the paper shredder is used, a user opens the lifting cover, places the paper to be shredded on the paper placing platform in a whole stack, then closes the lifting cover, the inner surface of the lifting cover presses the paper at the moment, the machine is started, the paper to be shredded is sequentially sucked into the paper shredding machine core from the paper inlet through the friction force of the paper feeding roller, the paper shredding machine core shreds the paper, and the shredded paper flows into the collecting barrel to finish the actions of automatic paper feeding and shredding.

However, in the process of feeding paper by the paper feeding roller, as the paper is continuously reduced, the pressure of the inner surface of the lifting cover on the paper is also reduced, so that the friction force generated between the paper feeding roller and the paper to be shredded is also continuously reduced, and thus the paper gripping capacity of the paper feeding roller is greatly reduced, and the phenomenon of non-feeding paper occurs, or because the friction force exists between the paper and the paper, a plurality of pieces of paper are sucked at one time, so that the machine is blocked and the paper cannot be shredded, thereby affecting the working quality and the working efficiency of the automatic paper feeding shredder.
