[0035] The working principle of this utility model:

[0036] When in use, the program is started through the control panel 104, and the documents to be processed are put into the interior of the shell 1 through the feed port 103. The motor 2 drives the first gear 211 to rotate through the rotating shaft 201, and drives the second gear 213 to rotate in the opposite direction through the first gear 211. At the same time, the first gear 211 and the second gear 213 respectively drive the first shredding roller 212 and the second shredding roller 214 to rotate in the opposite direction to shred the documents. The shredded documents fall onto the top of the partition plate 3. At this time, as the motor 2 drives the rotating shaft 201 to drive the transmission wheel 202 to rotate, the driven wheel 203 is driven and drives the rotation of the driven shaft 204. At the same time, the driven shaft 204 drives the rotation of the cam 205. At this time, the cam 205 knocks on the partition plate 3 to shake off the shredded documents and move them to the lower left. When the shredding work is completed, the pressure cylinder 4 is started through the control panel 104 to drive the pressure plate 401 to compress the shredded documents. When there are too many shredded papers in the collection box 501, they can be drawn out and cleaned.

[0037] In summary: the legal document shredding device, through the coordinated use of the shell 1, the motor 2, the partition plate 3, the pressure cylinder 4 and the collection box 501, solves the problem that when shredding documents, the fluffy shredded paper may pile up and take up too much space, making it inconvenient to shred a large number of documents, and when shredding documents, a large amount of shredded paper may be attached with static electricity, so some shredded paper may stick to the inside of the device, which is difficult to find and clean.
