[0002] An efficient paper medium destruction machine is a device specifically used for destroying paper documents to ensure that confidential information will not be leaked. It cuts paper documents into extremely fine pieces or particles to achieve the purpose of confidential and safe processing.

[0003] For example, a paper destruction machine for financial paper documents disclosed in the Chinese utility model patent with the publication number CN220759476U can drive a rotating shaft to rotate by starting a second motor, and the rotating shaft can drive multiple groups of crushing knives to rotate. Thus, under the action of multiple groups of crushing knives, the paper scraps falling into the crushing barrel can be subjected to secondary crushing treatment. Furthermore, through the setting, secondary crushing operation can be carried out on the paper, greatly improving the paper crushing effect and avoiding the risk of the document being restored and leaking confidential information.

[0004] However, after the paper is crushed by this device, the shredded paper pieces directly fall and are collected in a collection box. Since the shredded paper is in a fluffy state in the collection box, there will still be a large amount of space between the shredded paper pieces, and the storage capacity of the collection box cannot be reasonably utilized.

The rotation directions of the two cleaning rollers are opposite to those of the adjacent crushing rollers. Put the paper into the feeding chute. The paper is transported downward under the action of the two conveying rollers. When the paper passes through the crushing rollers, it is crushed, and the crushed paper falls into the interior of the blanking pipe. At the same time, under the action of the cleaning rollers, the shredded paper stuck on the crushing rollers also falls into the interior of the blanking pipe, reducing the influence of the shredded paper on the crushing effect of the crushing rollers.

One end of the crushing shaft 24 is rotatably connected to the inner wall of the blanking pipe 5.

[0034] In the embodiment of the present application, the implementation principle of an efficient paper medium destruction machine is as follows: Start the driving motor. The driving motor drives the two conveying rollers 3 to rotate. Under the action of the synchronous belt, the second gear 9 and the third gear 10, the two crushing rollers 7 rotate relatively. The rotation directions of the two cleaning rollers 8 are opposite to those of the adjacent crushing rollers 7. Put the paper into the feeding slot 2. The paper is transported downward under the action of the two conveying rollers 3. When the paper passes through the crushing rollers 7, it is crushed, so that the shredded paper falls into the inside of the blanking pipe 5. At the same time, under the action of the cleaning rollers 8, the shredded paper stuck on the crushing rollers 7 also falls into the inside of the blanking pipe 5, reducing the influence of the shredded paper on the crushing effect of the crushing rollers 7 and improving the crushing effect of the device.

[0035] Start the servo motor so that the servo motor drives the lead screw 12 and the driving gear 20 to rotate. Under the action of the driving gear 20, the driven gear 21 drives the worm gear 23 to rotate through the worm 22, so that the crushing shaft 24 drives the crushing blades to rotate, and the shredded paper scraps after crushing are crushed again, making the device crush the paper more thoroughly and having a better crushing effect.

[0036] When the shredded paper scraps fall into the interior of the collection box 6, under the action of the lead screw 12, the equipment box 11 reciprocates along the lead screw 12. During the movement of the equipment box 11, the moving gear 16 is deflected under the action of the toothed plate 17, causing the cam 15 to rotate. Under the action of the cam 15 and in cooperation with the spring rod 13, the moving frame 14 continuously reciprocates in the vertical direction, so that the limiting rod drives the pressing plate 18 to continuously move up and down, squeezing and compressing the shredded paper scraps accumulated in the collection box 6, increasing the storage capacity of the collection box 6, reducing the frequency of processing the shredded paper scraps in the collection box 6, and improving the user experience.
