Description

Technical Field

[0001] This invention relates to the field of paper shredder technology, specifically to a paper shredder with an automatic paper feeding mechanism. Background Technology

[0002] The common paper shredders in the present technology achieve the functions of paper cutting and shredding by setting up a dual-axis cutting structure. Users need to manually put the paper into the cutting area, and then the mechanical structure cuts the paper into small pieces.

[0003] However, existing paper shredders have some drawbacks during use. First, because users need to manually place the paper into the cutting area, there is a risk of paper jams. If multiple sheets of paper are placed in at the same time or the paper is too thick, it is easy for the paper to become stuck and unable to be cut, requiring manual clearing by the user. Second, because paper tends to adhere to the cutting shaft during cutting, it affects the cutting effect and the lifespan of the equipment; therefore, it does not meet the current requirements. To address this, we propose a paper shredder with an automatic paper feeding mechanism. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] This embodiment aims to facilitate solutions to the risk of paper jams during the cutting process of paper of different thicknesses and the problem of paper adhering to the surface of the cutting device. Please refer to [link to relevant documentation]. Figure 1-8 A paper shredder with an automatic paper feeding structure includes a support device 1, a drive device 2 installed on one side of the support device 1, a transmission system 3 assembled at the output end of the drive device 2, a drive device 4 connected to the drive device 2, a driven device 5 connected to one side of the drive device 4, a cutting device 6 connected to one side of the driven device 5, an automatic paper feeding device 7 assembled on one side of the cutting device 6, an adjusting device 8 fixedly connected to one side of the automatic paper feeding device 7, and a blower 9 installed inside the cutting device 6.

[0030] In this embodiment: the support device 1 includes a housing 101, which is composed of a bottom plate 102, a left side plate 103, a right side plate 104, a back plate 105, a front panel 106, and a cover plate 107. The left side plate 103 has a first sliding hole 1031, a second sliding hole 1032, a first sliding groove 1033, and a second sliding groove 1034. The right side plate 104 has the same groove as the left side plate 103. A transmission system 3 is mounted on one side of the left side plate 103. A support frame 1051 is fixedly connected to one side of the back plate 105, and a drive device 2 is connected to one side of the support frame 1051. A threaded groove 1061 is opened on one side of the front panel 106, and an adjustment chamber 1062 is fixedly connected to the other side of the front panel 106. The adjustment chamber 1062 is connected to the threaded groove 1061. An adjustment device 8 is installed inside. A recycling bin 108 is installed on one side of the base plate 102. The support device 1, consisting of the base plate 102, left side plate 103, right side plate 104, back plate 105, front panel 106 and cover plate 107, forms the housing 101, providing a stable support structure that can effectively support and fix the various components of the shredder, ensuring stable operation of the equipment. The left side plate 103 and right side plate 104 are respectively provided with sliding holes and sliding grooves, allowing the shredder's cutting size to be adjusted by sliding. The transmission system 3 is installed on the left side plate 103 and, in cooperation with the drive device 2, drives the cutting device 6 to cut the paper. The shredder's cutting size can be easily adjusted through the connection between the adjustment chamber 1062 and the threaded groove 1061, and the adjustment device 8 installed in the threaded groove 1061.

[0031] In this embodiment: the driving device 2 includes a motor 201 fixedly connected to one side of the support frame 1051. The output end of the motor 201 is fixedly connected to a drive gear 202. A transmission system 3 is assembled on one side of the drive gear 202. The motor 201 is used to drive the entire transmission system 3. The motor 201 has the characteristics of high-speed rotation and high torque output, which can effectively provide sufficient power to drive the transmission system 3.

[0032] In this embodiment: the active device 4 includes a first gear 401 meshing with the drive gear 202, a second gear 402 meshing with the first gear 401, a first fixed rod 403 rotatably connected to the center of the first gear 401, one end of the first fixed rod 403 fixedly connected to one side of the left side plate 103, and the other end of the first fixed rod 403 fixedly connected to one side of the right side plate 104. An anti-jamming groove 4021 is formed in the center of the second gear 402, and an anti-jamming block 4022 is rotatably connected within the anti-jamming groove 4021. The center of the anti-jamming block 4022 is hollow. The center of the anti-jamming block 4022 is rotatably connected to the second fixing rod 404. One end of the second fixing rod 404 is fixedly connected to one side of the left side plate 103, and the other end of the second fixing rod 404 is fixedly connected to one side of the right side plate 104. One side of the first gear 401 is rotatably connected to the first belt 405 through a shaft. One side of the second gear 402 is rotatably connected to the second belt 406 through a shaft. One side of the first belt 405 and the second belt 406 are connected to the driven device 5.

[0033] The active device 4 is connected by the meshing of gear 401 and gear 402. The driving device 2 provides driving force to the active device 4, which transmits power to the driven device 5 through the belt. The connection of fixed rod 403 and fixed rod 404 forms a stable transmission structure. The center of gear 402 has an anti-jamming groove 4021. An anti-jamming block 4022 is rotatably connected in the anti-jamming groove 4021. The center of the anti-jamming block 4022 is hollow and is rotatably connected to fixed rod 404. Through the design of anti-jamming groove 4021 and anti-jamming block 4022 in gear 402, there is a difference in the transmission of belt 405 and belt 406. This design can effectively prevent paper from getting stuck and blocked during the cutting process.

[0034] In this embodiment: the driven device 5 includes a third gear 501 rotatably connected to one end of the first belt 405 via a shaft, and a fourth gear 502 rotatably connected to one side of the second belt 406 via a shaft. The first belt 405 and the second belt 406 are connected to the same auxiliary component 503. The auxiliary component 503 includes an auxiliary block 5031 rotatably connected to the inner side of the first belt 405 and the second belt 406. The side wall of the auxiliary block 5031 is slidably connected to the first slide groove 1033 and the second slide groove 1034. An auxiliary groove 5032 is opened on one side of the auxiliary block 5031. An auxiliary spring 5033 is fixedly connected in the auxiliary groove 5032. The other end of the auxiliary spring 5033 is fixedly connected in the first slide groove. The center of the third gear 501 and the fourth gear 502 is a hollow structure.

[0035] A cutting device 6 is connected to one side of gears 3 and 4. A blower 9 is mounted on the other side of gears 3 and 4. The driven device 5 drives the cutting device 6 to rotate through the power transmitted from the driving device 4. The design of the driving device 4 enables the driven device 5 to work in coordination. The design of the auxiliary component 503 ensures that gears 3 and 4 will not be restricted from sliding by the tension of belts 1 and 2 during the sliding process. Figure 7 When the position shown is reached, the auxiliary spring 5033 inside the auxiliary block 5031 is in a compressed state. When the third gear 501 and the fourth gear 502 slide, the auxiliary spring 5033 inside the auxiliary block 5031 releases pressure, causing the auxiliary block 5031 to move along with the movement of the third gear 501 and the fourth gear 502. The center of the third gear 501 and the fourth gear 502 is a hollow structure, with a cutting device 6 connected to one side and a blower 9 assembled on the other side. The cutting device 6 is used to cut the paper into small pieces, while the blower 9 reduces the contact area between the paper and the cutting shaft by generating airflow, preventing the paper from adhering to the cutting shaft.

[0036] In this embodiment: the cutting device 6 includes a first fixing tube 601 and a second fixing tube 602. A third gear 501 is connected to one side of the first fixing tube 601, and a fourth gear 502 is fixedly connected to one side of the second fixing tube 602. A rotating slice 603 is fixedly connected to the side walls of the first fixing tube 601 and the second fixing tube 602. An automatic paper-feeding device 7 is provided at the gap of the rotating slice 603. Ventilation holes 604 are opened on the side walls of the first fixing tube 601 and the second fixing tube 602, and the ventilation holes 604 are located at the gap of the rotating slice 603. The cutting device 6 is composed of two components, the first fixing tube 601 and the second fixing tube 602, and is connected to the third gear 502. The connection between wheel 501 and gear 502 drives the first fixed tube 601 and the second fixed tube 602 to rotate, causing the rotating slices 603 on the side walls of the first fixed tube 601 and the second fixed tube 602 to rotate, thus achieving paper cutting. The structure of the fixed tubes is stable, which can ensure the stable operation of the cutting device 6. The side walls of the first fixed tube 601 and the second fixed tube 602 are provided with ventilation holes 604, which are located in the gaps of the rotating slices 603. This design can prevent the paper being cut from sticking to the cutting device 6 and causing paper jams through the air flow in the ventilation holes 604. At the same time, the movement of airflow can reduce the temperature during the cutting process.

[0037] In this embodiment: the automatic paper feeding device 7 includes a first paper feeding device 701 disposed on one side of the first fixed tube 601 and a second paper feeding device 702 disposed on one side of the second fixed tube 602. The first paper feeding device 701 includes a first support plate 7011 fixedly connected to one side of the support frame 1051. A first adjusting spring 7012 is fixedly connected to one side of the support frame 1051. A first automatic paper feeding plate 7013 is fixedly connected to the other end of the first adjusting spring 7012. The first automatic paper feeding plate 7013 is placed on one side of the first support plate 7011. The insertion block of the first automatic paper feeding plate 7013 is disposed in the gap of the rotating slice 603 of the first fixed tube 601.

[0038] The second paper-feeding device 702 includes a second automatic paper-feeding plate 7021 disposed at the gap between the rotating slices 603 of the second fixed tube 602. A second support plate 7022 is fixedly connected to one side of the front panel 106 below the second automatic paper-feeding plate 7021. A second adjusting spring 7023 is fixedly connected to the other side of the second automatic paper-feeding plate 7021. An adjusting device 8 is disposed at the other end of the second adjusting spring 7023. The automatic paper-feeding device 7 includes two paper-feeding devices, which are respectively disposed on both sides of the first fixed tube 601 and the second fixed tube 602. The first paper-feeding device 701 uses the first adjusting spring 7012 and the first support plate 7011 to make the insert on the first automatic paper-feeding plate 7013 fit against the side wall of the first fixed tube 601. The second paper-feeding device 702 can actively adjust the spring stress of the second adjusting spring 7023 through the adjusting device 8 to control the position between the first fixed tube 601 and the second fixed tube 602 to accommodate paper of different thicknesses.

[0039] In this embodiment, the adjusting device 8 includes an adjusting plate 801 fixedly connected to one end of the second adjusting spring 7023. The adjusting plate 801 is slidably connected in the adjusting chamber 1062. A screw 802 is rotatably connected to the other side of the adjusting plate 801. A knob 803 is fixedly connected to the other end of the screw 802. The screw 802 is bolted in the threaded groove 1061. The screw 802 is rotated by the knob 803, thereby causing the adjusting plate 801 to slide in the adjusting chamber 1062, realizing the position adjustment of the automatic paper feeding device 7. The position of the feeding plate can be conveniently adjusted by rotating the knob 803 to adapt to paper of different thicknesses.

[0040] In this embodiment, the blower device 9 includes a first air duct 901 rotatably connected to one side of the third gear 501. The side wall of the first air duct 901 is slidably connected to the first sliding hole 1031 via a slider. A second air duct 902 is rotatably connected to one side of the fourth gear 502. The side wall of the second air duct 902 is slidably connected to the second sliding hole 1032 via a slider. A fixed arc plate 903 is fixedly connected to the other side of the first air duct 901 and the second air duct 902. An external fan is connected to the first air duct 901 and the second air duct 902 to form an internal air duct. The slider connection can maintain the stability of the first air duct 901 and the second air duct 902 during the sliding process, avoiding deviation and shaking. The fixed arc plate 903 ensures that the air can only be discharged from the lower ventilation hole, allowing the cut paper scraps to fall into the recycling bin 108, effectively preventing backflow of air and leakage in other directions.

[0041] Working principle:

[0042] Working principle of the drive device: The start of the motor 201 causes the drive gear 202 on its output shaft to rotate, which drives the transmission system 3 to start working.

[0043] Working principle of the active device: By driving the gear 202 to rotate, the first gear 401 meshing with it will rotate, which in turn drives the second gear 402 to rotate. Due to the special design of the second gear 402, the second gear 402 can drive the second belt 406 to move after rotating a certain angle. Power is transmitted to the driven device 5 through the first belt 405 and the second belt 406.

[0044] Working principle of the driven device: Power is transmitted to gear 3 501, gear 4 502 and auxiliary block 5031 through belt 1 405 and belt 2 406. The rotation of gear 3 501 and gear 4 502 causes the cutting device 6 fixedly connected to them to start working. When gear 3 501 and gear 4 502 move horizontally, the auxiliary component 503 can prevent them from being restrained by belt 1 405 and belt 2 406 and stop moving.

[0045] Working principle of the cutting device: The rotation of gear 3 501 and gear 4 502 causes the fixed tube 1 601 and fixed tube 2 602, which are fixedly connected to them, to start rotating, thereby driving the rotating slice 603 to rotate and start cutting the paper.

[0046] Working principle of the automatic paper feeding device: The paper is broken by the rotation and cutting of the first fixed tube 601 and the second fixed tube 602. After the paper is cut, some of the paper may be adsorbed on the side walls of the first fixed tube 601 and the second fixed tube 602 as well as the side wall of the blade. By rotating the first fixed tube 601 and the second fixed tube 602 and setting the first automatic paper feeding plate 7013 and the second automatic paper feeding plate 7021, the paper is peeled off from the adsorbed surface when it passes the positions of the first automatic paper feeding plate 7013 and the second automatic paper feeding plate 7021.

[0047] Working principle of the adjustment device: By rotating the knob 803, the screw 802 moves horizontally, which in turn drives the adjustment plate 801, which is rotatably connected to the other end of the screw 802, to move horizontally. This causes the second adjustment spring 7023 in the second paper feeding device 702 to be subjected to the required stress, thereby adjusting the position between the first fixed tube 601 and the second fixed tube 602.

[0048] Working principle of the blower: The blower is connected to an external fan through the No. 1 air duct 901 and the No. 2 air duct 902 to form an internal air duct. The blower is fixedly connected to the No. 1 air duct 901 and the No. 2 air duct 902 by a fixed arc plate 903, so that the air can only be discharged from the lower ventilation hole. The blower is slidably connected to the side wall of the No. 1 air duct 901 and the No. 2 air duct 902 by a slider in the first sliding hole 1031 and the second sliding hole 1032, so that the fixed arc plate 903 in the No. 1 air duct 901 and the No. 2 air duct 902 will not shift during the sliding process.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
