Description

Technical Field

[0001] The present invention relates to the technical field of paper cutters, and in particular to a new type of automated paper cutting device. Background Art

[0002] Paper cutters are traditional products used to handle the paper cutting requirements in the later stage of printing. From mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer-programmed, color-display, fully image-operated guided visualization processing, and computer-aided cutting external programming and editing production data cutting systems, the production preparation time is shorter, the cutting accuracy is higher, and the operation is safer.

[0003] In the existing paper cutters, when the paper needs to be cut on all four sides, the paper needs to be manually adjusted in direction one by one before cutting. When the paper is thick during cutting, taking out the paper and turning it around is not only very cumbersome but also increases the workload of the staff. Moreover, the existing paper cutters cannot collect the cut waste paper scraps, resulting in the waste paper scraps being scattered everywhere, causing inconvenience to the later cleaning and being not conducive to environmental protection.

[0034] Refer to Figures 1-9 , a new type of automatic paper cutting device, comprising a main body 1; a cutting part 2, which is arranged on the upper side of the main body 1 for paper cutting; a waste paper collection component, which is arranged in the main body 1 for collecting the cut waste paper scraps; a pushing mechanism, which is arranged on the upper side of the main body 1 for adjusting the length of the paper to be cut; a turntable 11, which is arranged in the main body 1 for placing the paper to be cut; a lifting mechanism, which is arranged in the main body 1 for driving the turntable 11 and the paper placed on the turntable 11 to rise; an angle adjustment mechanism, which is arranged in the main body 1 for adjusting the direction of the paper placed on the turntable 11; the lifting mechanism is used to drive the paper to adjust its height, and when the paper is adjusted in height, the angle adjustment mechanism is used to drive the paper to rotate by 90°, thus replacing manual flipping to adjust the angle of the paper, which can greatly reduce the workload of the staff, and the waste paper collection component is used to collect the cut waste paper scraps uniformly, ensuring the cleanliness of the location where the device is located and being conducive to environmental protection.

[0035] Refer to Figure 3 , the lifting mechanism includes a second groove 12 opened in the main body 1, a second limiting rod 13 is fixedly connected in the second groove 12, a threaded plate 15 is slidably connected to the circumferential surface of the second limiting rod 13, a lifting screw rod 14 is rotatably connected in the second groove 12, the threaded plate 15 is threadedly connected to the circumferential surface of the lifting screw rod 14, a second driving motor 17 is fixedly connected to the bottom end of the main body 1, and the second driving motor 17 is connected to the lifting screw rod 14 through a coupling; after cutting is completed, the second driving motor 17 is started to drive the lifting screw rod 14 to rotate, and the rotation of the lifting screw rod 14 drives the threaded plate 15 to move upward.

[0036] Refer to Figures 5-8, the angle adjustment mechanism includes a fourth groove 20 formed in the threaded plate 15. A first rotating shaft 21 is rotatably connected in the fourth groove 20. The first rotating shaft 21 movably penetrates upward through the top end of the threaded plate 15 and extends upward. The turntable 11 is fixedly connected to the top end of the first rotating shaft 21. A worm gear 22 is fixedly connected to the circumferential surface of the first rotating shaft 21. A worm 23 is rotatably connected in the fourth groove 20. The worm 23 is connected to the worm gear 22 through a coupling; a third groove 16 is formed in the side end of the threaded plate 15. A fifth groove 24 is formed in the threaded plate 15. A second rotating shaft 25 is rotatably connected in the fifth groove 24. The second rotating shaft 25 movably penetrates outward into the third groove 16. A first driven gear 19 is fixedly connected to the circumferential surface of the second rotating shaft 25. A driving rack 18 is fixedly connected in the second groove 12. The first driven gear 19 meshes with the driving rack 18; a driving gear 26 is fixedly connected to the circumferential surface of the second rotating shaft 25. A second driven gear 27 is rotatably connected to the side wall of the fifth groove 24. The worm 23 movably penetrates outward into the fifth groove 24. A rotating plate 35 is fixedly connected to the side end of the worm 23. A pawl 31 is rotatably connected to the side end of the rotating plate 35. A ratchet 28 is fixedly connected to the circumferential inner wall of the second driven gear 27. A fixed baffle 32 and a positioning plate 29 are fixedly connected to the side end of the rotating plate 35. The pawl 31 is in intermittent contact with the fixed baffle 32. A pushing spring 30 is fixedly connected to the side end of the positioning plate 29. The side end of the pushing spring 30 is fixedly connected to one end of the pawl 31 close to the positioning plate 29;The lifting screw rod 14 rotates to drive the threaded plate 15 to move upward. The upward movement of the threaded plate 15 drives the first driven gear 19 to synchronously move upward. When the first driven gear 19 moves upward synchronously, since it meshes with the driving rack 18, the driving rack 18 drives the first driven gear 19 to rotate counterclockwise. The rotation of the first driven gear 19 drives the second rotating shaft 25 to rotate counterclockwise. The rotation of the second rotating shaft 25 drives the driving gear 26 to rotate counterclockwise. The rotation of the driving gear 26 drives the second driven gear 27 to rotate clockwise. The clockwise rotation of the second driven gear 27 drives the ratchet wheel 28 to rotate clockwise. When the ratchet wheel 28 rotates clockwise, the pawl 31 disengages from the ratchet teeth inside the ratchet wheel 28. The ratchet wheel 28 drives the rotating plate 35 to rotate. The rotation of the rotating plate 35 drives the worm 23 to rotate. The rotation of the worm 23 drives the worm gear 22 to rotate. The rotation of the worm gear 22 drives the first rotating shaft 21 to rotate. The rotation of the first rotating shaft 21 drives the turntable 11 to rotate 90° during the upward movement, so that the paper on the turntable 11 also rotates 90°. At the same time, when the lifting screw rod 14 drives the threaded plate 15 to descend, the driving rack 18 drives the first driven gear 19 to rotate in the reverse direction. The reverse rotation of the first driven gear 19 ultimately drives the second driven gear 27 to rotate counterclockwise. When the second driven gear 27 rotates counterclockwise, the pawl 31 cannot engage with the ratchet teeth of the ratchet wheel 28. Then, when the second driven gear 27 rotates counterclockwise, the rotating plate 35 does not follow the rotation. This is used to replace manual angle adjustment, and at the same time, there is no need to set up an additional driving mechanism to drive the angle adjustment mechanism separately.;

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, an improvement is made. Refer to Figure 9 , the waste paper collection assembly includes a storage groove 3 opened in the main body 1 of the machine, and a storage box 4 is slidably connected in the storage groove 3; a receiving groove 33 communicating with the storage groove 3 is opened in the main body 1 of the machine, and an air extractor 34 is provided in the receiving groove 33. A plurality of air permeable holes are provided at the bottom end of the storage box 4; the air extractor 34 is used to inhale air to adsorb waste paper into the storage box 4 for storage.

[0039] Embodiment 3

[0040] On the basis of Embodiment 1, an improvement is made. Refer to Figure 2, the paper pushing mechanism includes a first mounting block 5 and a second mounting block 51 fixedly connected to both sides of the top end of the main body 1. First grooves 7 are formed in both the first mounting block 5 and the second mounting block 51. A first limiting rod 8 is fixedly connected in one of the first grooves 7, and a driving lead screw 9 is rotatably connected in the other first groove 7. A push plate 6 is threadedly connected to the circumferential surface of the driving lead screw 9, and the push plate 6 is slidably connected to the circumferential surface of the first limiting rod 8. A first driving motor 10 is fixedly connected to the side end of the first mounting block 5, and the first driving motor 10 is connected to the driving lead screw 9 through a coupling; the paper is placed above the turntable 11. By starting the first driving motor 10 to drive the driving lead screw 9 to rotate, the driving lead screw 9 rotates to move the push plate 6 to a specified position, and the distance between the position of the push plate 6 and the cutting blade in the cutting part 2 is the length that the paper needs to be cut.

[0041] However, as is well known to those skilled in the art, the working principle and wiring method of the exhaust fan 34 are common knowledge, and they all belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0042] The working principle and usage process of this technical solution are as follows: The paper is placed on the upper side of the turntable 11. By starting the first driving motor 10, the driving lead screw 9 is driven to rotate. The rotation of the driving lead screw 9 moves the push plate 6 to a specified position. The distance between the position of the push plate 6 and the cutting blade in the cutting part 2 is the length that the paper needs to be cut. The staff uses their hands to push and tamp the paper to make the paper fit against the side end of the push plate 6. Then, by starting the cutting part 2, the paper is cut. After cutting, by starting the second driving motor 17, the lifting lead screw 14 is driven to rotate. The rotation of the lifting lead screw 14 drives the threaded plate 15 to move upward. The upward movement of the threaded plate 15 drives the first driven gear 19 to rise synchronously. When the first driven gear 19 rises synchronously, since it meshes with the driving rack 18, the driving rack 18 drives the first driven gear 19 to rotate counterclockwise. The rotation of the first driven gear 19 drives the second rotating shaft 25 to rotate counterclockwise. The rotation of the second rotating shaft 25 drives the driving gear 26 to rotate counterclockwise. The rotation of the driving gear 26 drives the second driven gear 27 to rotate clockwise. The clockwise rotation of the second driven gear 27 drives the ratchet 28 to rotate clockwise. When the ratchet 28 rotates clockwise, the pawl 31 disengages from the ratchet teeth in the ratchet 28. The rotation of the ratchet 28 drives the rotating plate 35 to rotate. The rotation of the rotating plate 35 drives the worm 23 to rotate. The rotation of the worm 23 drives the worm gear 22 to rotate. The rotation of the worm gear 22 drives the first rotating shaft 21 to rotate. The rotation of the first rotating shaft 21 drives the turntable 11 to rotate 90° during the upward movement, so that the paper on the turntable 11 also rotates 90°. At the same time, when the lifting lead screw 14 drives the threaded plate 15 to descend, the driving rack 18 drives the first driven gear 19 to rotate in the reverse direction. The reverse rotation of the first driven gear 19 ultimately drives the second driven gear 27 to rotate counterclockwise. When the second driven gear 27 rotates counterclockwise, the pawl 31 cannot engage with the ratchet teeth of the ratchet 28. Then, when the second driven gear 27 rotates counterclockwise, the rotating plate 35 does not rotate accordingly, thus replacing manual angle adjustment, and at the same time, there is no need to set up an additional driving mechanism to drive the angle adjustment mechanism separately.

[0043] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
