Description
Technical Field
[0001] The utility model relates to the technical field of paper shredders, in particular to a paper shredder with a rotating inner barrel. Background Art
[0002] The shredder is composed of a set of rotating blades, a paper comb and a drive motor. Paper is fed in between the interlocking blades and cut into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of the paper after it is shredded by the shredder. According to the composition of the shredder, the existing shredding methods include: broken, granular, segmented, foamy, strip, filamentous, etc.
[0003] However, the existing paper shredders still have the following shortcomings: 1. In the existing technology, most of the paper is put into the shredder through the paper outlet on the top of the shredder for shredding. If there are too many papers, it takes time to wait, which reduces the work efficiency; 2. In the above existing shredding methods, text and other information are still left on the paper scraps. There is a risk of leakage through proper splicing and reasoning. Therefore, we propose a shredder with a rotating inner barrel. Utility Model Content
