Description

Technical Field

[0001] The utility model relates to the technical field of paper shredding equipment, in particular to a paper shredding equipment. Background Art

[0002] A large number of paper documents are used at work. Since the contents of the documents are confidential, they will be shredded when they are no longer needed. A shredder is a machine used to cut paper and other materials into small pieces. These devices are often used to destroy documents to protect the security of sensitive information. They can also be used to recycle and reuse paper and other materials. There are many types of shredders, including manual and electric models. Manual shredders require users to operate them with a handle or lever, while electric shredders are driven by a motor. Electric shredders are usually faster and more efficient than manual models.

[0003] In the prior art, when the paper shredder is in use, a motor is used to drive the shredding roller to rotate. When paper is put into the paper shredder, it will be torn into pieces by the shredding roller. However, the paper shredders on the market usually have only single-stage shredding, which is not thorough enough. Some paper shredders with multi-stage shredding use multiple motors in combination, which results in a high cost of the paper shredder. After the paper shredder is used, the shredded paper will fall into a storage box. However, when the shredded paper is piled up, there are certain gaps between the shredded paper, so the shredded paper will occupy a larger space in the storage box, so that the storage box cannot hold more shredded paper, and the space utilization rate is low. Therefore, a paper shredder is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a paper shredding device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A paper shredding device comprises a bottom plate, the top of the bottom plate is fixedly connected to a side frame, one side of the side frame is rotatably connected to a box cover, the top of the side frame is fixedly connected to a storage plate, the bottom of the storage plate is provided with a discharge hole that penetrates the storage plate, one side of the side frame is provided with a through hole that penetrates the side frame, a lead screw is provided on the inner side of the through hole, one end of the lead screw is rotatably connected to a rotating joint, a side of the rotating joint away from the lead screw is fixedly connected to a clamping plate, a threaded cylinder is spirally connected to the outer side of the lead screw, one end of the lead screw is fixedly connected to a turntable away from the rotating joint, the top of the storage plate is fixedly connected to a crushing box, the top of the crushing box is fixedly connected to a rotating shaft, and the outer side of the rotating shaft is fixedly connected to a top cover.

[0008] Preferably, the number of the rotating motor, crushing shaft, first transmission wheel, conveyor belt, second transmission wheel and crushing shaft are two, the crushing shaft and crushing shaft are both rotatably connected to the crushing box, and the inner side of the conveyor belt is tightly fitted with the outer side of the first transmission wheel and the outer side of the second transmission wheel.

[0009] Preferably, the storage plate is the same size as the bottom plate, the shape of the discharge hole is a trapezoidal design, and the inner diameter of the through hole is larger than the outer diameter of the lead screw.

[0010] Preferably, the top end of the clamping plate is slidably connected to the bottom end of the storage plate, the bottom end of the clamping plate is slidably connected to the top end of the bottom plate, and the threaded tube is fixedly connected to the outside of the side frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the storage space utilization rate of the paper shredding device is higher by providing the storage plate, the material discharge hole, the through hole, the lead screw, the rotary joint, the pressing plate, the threaded cylinder and the turntable. When the shredded paper moves to the top of the bottom plate through the material discharge hole located on the inner side of the storage plate, the turntable is shaken, the turntable drives the lead screw to rotate, the lead screw rotates and moves inside the threaded cylinder, the movement of the lead screw drives the rotary joint to rotate, and the pressing plate is pushed to slide on the top of the bottom plate and the bottom of the storage plate. The pressing plate continuously presses the shredded paper, thereby improving the space utilization rate of the paper shredding device;

[0013] 2. In the utility model, by providing a shredding box, a rotating motor, a shredding shaft, shredding blades, a first transmission wheel, a conveyor belt, a second transmission wheel, a crushing shaft and a crushing blade, the shredding effect of the paper shredding device is better, and at the same time, the cost of the paper shredding device can be prevented from increasing. When using the device, first lift the top cover, rotate the rotating shaft, open the top cover, put the paper documents to be shredded into the inside of the shredding box, and then start the rotating motor. The rotating motor drives the shredding shaft and the shredding blades to rotate, and at this time, the first transmission wheel follows the rotation. Due to the limitation of the conveyor belt, the rotation of the first transmission wheel drives the second transmission wheel to rotate, and the second transmission wheel drives the crushing shaft and the crushing blades to rotate. After the paper documents enter the shredding box, they are firstly crushed by the crushing blades, and then by the secondary crushing of the crushing blades. This design makes the shredding effect of the paper shredding device better, and by providing the first transmission wheel, the conveyor belt and the second transmission wheel, two motors can be replaced, thereby reducing the cost of the paper shredding device.
