Description

Technical Field

[0001] The utility model belongs to the technical field of small-sized paper shredding equipment, and more specifically, particularly relates to a small-sized paper shredding equipment. Background Art

[0002] Small shredders are mainly used to protect sensitive information, especially when handling documents. Their main function is to prevent confidential documents from being maliciously obtained by others and to avoid identity theft, information leakage and other issues. By cutting documents into small pieces, they cannot be restored, which improves the security of data. Small shredders are suitable for homes, offices, and various organizations and institutions.

[0003] When shredding paper, the staff of some small shredders will directly put the paper with staples into the small shredders. Since the staples are made of metal and have high hardness, the shredding blades will be damaged during shredding, which shortens the service life of the small shredders. At the same time, the paper falls into the collection trough after shredding. Since the shredded paper is relatively fluffy, the debris is difficult to fit together, so it will take up a lot of space, require frequent cleaning, and increase the workload.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a small paper shredding device is provided to achieve the purpose of having more practical value. Utility Model Content

[0009] Furthermore, an inlet 2 is provided on one side of the box body, one side of the inlet 2 is connected to the groove 2, a cutting groove is provided at the bottom of the groove 2 just below the cutting knife, a discharge port 2 is provided on the other side of the bottom of the groove 2, and the bottom of the discharge port 2 is connected to the top of the collecting tank.

[0010] Furthermore, a chamber 2 is provided on one side of the box body close to the slide groove 1, a motor 2 is installed on one side of the chamber 2, and one end of the screw rod 2 passes through one side of the chamber 2 and is connected to the output end of the motor 2.

[0011] Furthermore, a chamber three is provided on one side of the collection drawer near the slide groove two, a motor three is installed on one side of the chamber three, and one end of the screw rod two passes through one side of the chamber three and is connected to the output end of the motor three.

[0012] Furthermore, a control module is provided on the upper end surface of the box.

[0013] Furthermore, a plurality of chopping blades installed on the periphery of a pair of the rotating shafts are staggeredly distributed.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the coordinated use of motor 2, screw rod 1, connecting block and cutting knife, when there is a staple on one side of the paper to be shredded, the side of the paper with the staple is pushed into groove 1 through entrance 2, and motor 2 is started. Motor 2 drives screw rod 1 to rotate. Since screw rod 1 is threadedly connected to slider 1, the rotation of screw rod 1 drives slider 1 to move to one side, and slider 1 drives the connecting block to move to one side. The connecting block drives the cutting knife to move to one side through the mounting block. When the cutting knife moves to one side, the side of the paper with the staple is cut off, thereby avoiding directly putting the staple into the shredding blade together with the paper and damaging the shredding pieces, thereby extending the service life of the small paper shredding equipment.

[0016] Through the coordinated use of motor three, screw rod two and extrusion plate, when the paper is shredded and falls into the collection drawer, motor three is started, and motor three drives screw rod two to rotate. Since screw rod two is threadedly connected with slider two, when screw rod two rotates, it drives slider two to move to one side, and slider two drives the extrusion plate to move to one side, so that the paper debris can be compacted, so that the collection drawer can accommodate more debris, thereby reducing the number of cleaning times and reducing the workload.

Since the pair of gears 204 are meshed with each other, the gear 204 drives the other gear 204 to rotate, thereby driving the pair of rotating shafts 201 to rotate, and the pair of rotating shafts 201 drive a number of shredding blades 202 to rotate to shred paper.

[0032] Among them, an entrance 102 is provided on one side of the box body 1, and one side of the entrance 102 is connected with the groove 3.

[0036] A plurality of chopping blades 202 are installed on the periphery of a pair of rotating shafts 201 and are staggeredly distributed.

[0037] The working principle of this embodiment:

[0038] By the coordinated use of the motor 2 901, the screw rod 1 302, the connecting block 4 and the cutting knife 403, when there is a staple on one side of the paper to be shredded, the side of the paper with the staple is pushed into the groove 1 2 through the entrance 2 102, and the motor 2 901 is started. The motor 2 901 drives the screw rod 1 302 to rotate. Since the screw rod 1 302 is threadedly connected with the slider 1 401, the screw rod 1 302 drives the slider 1 401 to move to one side when it rotates, and the slider 1 401 drives the connecting block 4 to move to one side. The connecting block 4 drives the cutting knife 403 to move to one side through the mounting block 402. When the cutting knife 403 moves to one side, the side of the paper with the staple is cut off, thereby avoiding directly putting the staples into the shredding blade 202 together with the paper for shredding, thereby damaging the shredded pieces, and thus extending the service life of the small paper shredding equipment. The cut staples enter the collecting tank 5 through the feeding port 2 304, and then the paper after the staples are cut off passes through the entrance 10 1 is put into the groove 2, and the motor 801 is started. The motor 801 drives one of the gears 204 to rotate. Since the pair of gears 204 are meshed with each other, the gear 204 drives the other gear 204 to rotate, thereby driving the pair of rotating shafts 201 to rotate. The pair of rotating shafts 201 drives a number of shredding blades 202 to rotate to shred the paper. The shredded paper enters the collecting trough 5 through the feeding trough 203. Through the coordinated use of the motor 3 1001, the screw rod 2 602 and the extrusion plate 7, when the paper is shredded and falls into the collecting drawer 6, the motor 3 1001 is started. The motor 3 1001 drives the screw rod 2 602 to rotate. Since the screw rod 2 602 is threadedly connected with the slider 2 701, the screw rod 2 602 drives the slider 2 701 to move to one side when it rotates. The slider 2 701 drives the extrusion plate 7 to move to one side, so that the paper debris can be compacted, so that the collecting drawer 6 can accommodate more debris, thereby reducing the number of cleaning times and reducing the labor.
