Technical Field

[0001] This application relates to the field of paper shredder technology, specifically a fast paper shredder for accounting and finance that prevents paper jams. Background Technology

[0002] A high-speed paper shredder is an office device used to quickly shred paper, documents, and other media into small particles or strips. It is characterized by high-speed rotating blades, usually with a double-blade staggered shearing structure, to achieve efficient paper shredding and thus prevent information leakage. However, due to the frequent need for document destruction and frequent use, traditional paper shredders often experience paper jams when processing large amounts of accounting documents due to issues such as paper sticking together and paper scraps remaining, which seriously affects work efficiency. As a result, after long-term use, paper scraps and fibers easily adhere to the blades. These residual debris will gradually accumulate in the gaps between the blades, causing subsequent paper to get stuck.

[0003] Therefore, it is necessary to provide a fast, anti-jamming paper shredder for accounting purposes to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a fast paper shredder for accounting and finance that prevents paper jams. By setting a brush at the end of the shredder blade, the residual paper scraps and fibers on the blade are effectively removed by the contact between the shredder blade and the brush when the shredder blade rotates, thereby enabling the entire shredder assembly to have a paper jam prevention function during use.

[0005] The technical solution adopted by this application to solve its technical problem is: a fast paper shredder for accounting and finance to prevent paper jams, including a paper shredding assembly. The paper shredding assembly includes a main body with a feed inlet. The main body is equipped with a crushing module and a cleaning module. The crushing module includes a fixed base and two sets of relatively staggered rotating paper shredders and a drive module for driving their rotation.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0016] like Figures 1-7 As shown, this application provides a fast paper shredder for accounting and finance, including a paper shredder assembly 10. The paper shredder assembly 10 includes a main body 11, which is made of metal. The main body 11 has a paper inlet 12. The size of the paper inlet 12 is precisely adapted to the paper of commonly used accounting and finance documents, and the edges of the paper inlet 12 are rounded to avoid scratching the paper edges and improve the smoothness of paper feeding.

[0017] The main body 11 has a crushing module inside, which includes a fixing seat 14 fixedly installed inside the main body 11. The opening of the fixing seat 14 is aligned with the feed port 12 to ensure that the paper can fall accurately into the crushing area.

[0018] Meanwhile, the bearing on the fixed base 14 is equipped with two sets of relatively staggered and rotating paper shredders 15. The paper shredders 15 are made of high-hardness tungsten steel, and the blades are arranged in a staggered serrated pattern. The two sets of paper shredders 15 can be aligned with the feed port 12 to ensure that the paper is cut without deviation after entering.

[0019] The fixed base 14 is fixedly installed with a drive module for driving two sets of paper shredders 15. The drive module includes a motor 161 fixedly installed on the fixed base 14. The motor 161 is a variable frequency speed control motor, which can adapt to the paper shredding needs of financial documents of different thicknesses. At the same time, several sets of meshing gears 16 are fixedly installed on both the fixed base 14 and the paper shredders 15. By starting the motor 161 to drive the gear 16, the two sets of paper shredders 15 can rotate at high speed on the fixed base 14. When the paper enters the opening on the fixed base 14 through the feed port 12, the paper will come into contact with the two sets of rotating paper shredders 15, and the paper can be successfully shredded by the paper shredders 15.

[0020] Meanwhile, a receiving box 13 is slidably installed on the inner bottom of the main body 11. The receiving box 13 can be located at the bottom of the fixed base 14, so that the scraps generated by the paper shredder 15 after shredding the paper can be temporarily collected and stored in the receiving box 13. The receiving box 13 can be slid out on the main body 11 through the guide rail, so that the scraps stored inside the receiving box 13 can be processed later.

[0021] A cleaning module is fixedly installed on the mounting base 14. The cleaning module includes a fixing strip 17 fixedly installed on the mounting base 14. The fixing strip 17 is made of aluminum alloy. A brush 171 with equidistant arrangement is fixedly installed on one end of the fixing strip 17 near the shredder 15. The brush 171 is made of wear-resistant nylon bristles. The brush 171 can make close contact with the outer wall of the shredder 15. The contact pressure is maintained within a certain range through elastic design, which can effectively clean up the debris without excessively wearing out the blade. The two brushes 171 have a space between them to accommodate the edge of the shredder 15. The width of the space is adapted to the thickness of the shredder 15 blade, so that the shredder 15 will not affect the use and storage of the brushes 171 when it rotates. When there are residual scraps on the shredder 15, the continued rotation of the shredder 15 will cause the brushes 171 to come into contact with the shredder 15, so that the brushes 171 can clean the residual scraps on the shredder 15.

[0022] Meanwhile, a curved elastic element 174 is fixedly installed on the inner side of the fixed base 14. The elastic element 174 is initially popped outward. The elastic element 174 can extend to the surface of the brush 171. A pressure plate 175 is fixedly installed on the end of the elastic element 174 near the brush 171. The pressure plate 175 is made of rubber and contacts the brush 171. Both the fixed base 14 and the elastic element 174 are fixedly installed with a telescopic rod 176 that can extend and retract with the movement of the elastic element 174. The telescopic rod 176 can limit the movement direction of the elastic element 174. When the brush 171 contacts the side wall of the shredder 15 for cleaning, the debris on the shredder 15 may come into contact with the brush 171 and cause it to be pushed upwards. Over time, this can cause the brush 171 to gradually stop contacting the shredder 15. To address this, the elastic element 174 and the pressure plate 175 push the brush 171 to one side, blocking the brush 171 from being pushed. This ensures that the brush 171 is always reset and maintains the contact pressure with the shredder 15, while also preventing the brush bristles from deforming due to excessive pushing angle.

[0023] A fixing plate 172 is fixedly installed on the fixing strip 17. At the same time, a bolt 173 is provided on the fixing plate 172, which passes through itself and is threaded to the fixing seat 14. The bolt 173 enables the fixing strip 17 to be quickly installed on the fixing seat 14, thereby facilitating the replacement of the brush 171 and the maintenance of the cleaning module.

[0024] Additional explanation: Each of the fixed bases 14 is provided with a discharge port 18 and two sets of troughs 177. The two sets of troughs 177 are located on both sides of the discharge port 18. At the same time, the troughs 177 are close to the space between the shredder 15 and the brush 171. Thus, the shredded paper cleaned by the brush 171 on the shredder 15 can be discharged through the troughs 177, and the paper cleaned by the two sets of shredders 15 can be discharged through the discharge port 18. Both are collected by the collection box 13.

[0025] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
