Description

Technical Field

[0001] The utility model relates to the technical field of paper shredding, in particular to a device for shredding and destroying discarded paper archives. Background Art

[0002] Paper archives are archives that use paper as a carrier, such as the originals and manuscripts of official documents, drawings, letters, telegrams, household registers, account books, contracts, certificates, manuscripts, diaries, notes, and family trees that are kept for reference. Archives refer to original records of various forms with preservation value that are directly formed by people in various social activities. Archival files contain confidential information and need to be destroyed to prevent leaks, so a shredding device is needed to shred paper archives.

[0003] Among them, a paper destruction machine for financial paper documents disclosed in application number CN202322428933.8 is also an increasingly mature technology. By starting the first motor, the first motor can drive a group of turntables to rotate. While one group of turntables rotates, the other group of turntables can be driven to rotate by the action of the conveyor belt, thereby driving a group of second circular gears to rotate. A group of second circular gears can drive another group of second circular gears to rotate by meshing with another group of second circular gears. The two groups of second circular gears can drive two groups of connecting shafts to rotate. The two groups of connecting shafts can drive two groups of conveying wheels to rotate, thereby conveying paper by the action of the two groups of conveying wheels. Furthermore, through the setting, the document paper can be conveyed to the shredding box instead of being manually pushed, which effectively avoids the situation where the document paper moves backward and improves practicality.

[0004] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0005] This type of destruction machine requires manual feeding of paper into the feed port one by one, which increases the working time of the staff, making the destruction machine less efficient, and there is a possibility that the shredded documents can be restored, thus causing the risk of leaking confidential information. Utility Model Content

[0006] The utility model aims to provide a device for shredding and destroying waste paper files, so as to solve the problems of increased labor time and the possibility of restoration of shredded files proposed in the above-mentioned background technology.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] 1. The contraction of the support rod drives the T-plate downward, and the T-plate drives the support rod to slide along the sliding groove, thereby changing the pressing plate to an inclined setting. The motor drives the shaft rod and the roller frame set on the outside to rotate synchronously. Since the roller frame is made of rubber, the files inclined at the bottom of the pressing plate are driven to rotate and transported to the surface of the guide plate and then guided to between the two extrusion cylinders through its rotation, so as to facilitate automatic feeding without the need for staff to put files one by one and delay time;

[0025] 2. The first crushing roller is driven to rotate by the motor. Since a driving gear and a driving wheel are provided at one end of the first crushing roller, and a main gear and a driven wheel are provided at one end of the first center shaft, the driving wheel drives the driven wheel to rotate through the conveyor belt, so that the first center shaft rotates synchronously, and then the extrusion device works.
