[0002] In modern office, printing, packaging and many other industries, paper cutters are an indispensable piece of equipment, undertaking the important task of cutting paper into specific sizes. From cutting daily office documents to processing books and brochures in the printing industry, and then to processing packaging paper in the packaging industry, paper cutters are widely used.

[0003] However, traditional paper cutters have limited adaptability to paper sizes. For paper of different lengths, operators often need to manually use positioning tools to hold the paper against the side before cutting to prevent misalignment and inaccurate cutting. The operation is cumbersome and time-consuming, resulting in low work efficiency. Moreover, there are certain safety hazards, as operators may be injured due to negligence. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a paper cutting mechanism for a paper cutter with good positioning effect, which solves the problem of risks caused by operators manually using positioning tools before cutting.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A paper cutting mechanism for a paper cutter with good positioning effect includes: a base, on which a paper cutting device is fixedly connected to the outer wall of the top of the base; and a positioning device, on which the outer wall of the top of the base is fixedly connected to the outer wall of the bottom of the positioning device. The positioning device includes a positioning seat, on which a moving groove and a positioning groove are formed on the outer wall of the top of the positioning seat. A lead screw is rotatably connected to the inner wall of the moving groove, and a bidirectional threaded rod is rotatably connected to the inner wall of the positioning groove. A push plate is threadedly connected to the outer wall of the lead screw, and positioning plates are symmetrically threadedly connected to the outer wall of the bidirectional threaded rod. A scale is fixedly connected to the inner wall of the top of the positioning seat, and connecting plates are symmetrically fixedly connected to the outer wall of the top of the positioning seat. A slide rod is fixedly connected to the inner wall of the connecting plate, and a baffle is slidably connected to the outer wall of the slide rod. Compression springs are symmetrically fixedly connected to the outer wall of the baffle.

[0009] Preferably, the outer wall of the push plate is slidably connected to the inner wall of the moving groove. By rotating the lead screw, the rotation of the lead screw is converted into the linear movement of the push plate along the axis of the lead screw in the moving groove. The outer wall of the positioning plate is slidably connected to the inner wall of the positioning groove. By rotating the bidirectional threaded rod, the rotation of the bidirectional threaded rod will cause the two positioning plates to move relative to each other along the inner wall of the positioning groove. The scale is set below the push plate, and the operator can adjust the position of the push plate according to the scale fixedly connected to the inner wall of the top of the positioning seat.

[0010] Preferably, the connecting plate is located on the side away from the push plate, the outer wall of the compression spring on the side away from the baffle is fixedly connected to the inner wall of the connecting plate, and the outer wall of the bottom of the baffle is slidably connected to the outer wall of the top of the positioning seat. When the paper squeezes the baffle, the baffle slides along the slide rod and compresses the compression spring under the pushing force of the paper. The reaction force generated by the compression spring will make the baffle press tightly against the side of the paper.

[0011] Preferably, the paper cutting device includes a paper cutting frame, a hydraulic rod is fixedly connected to the inner wall of the top of the paper cutting frame, a paper cutting knife is fixedly connected to the outer wall of the bottom of the hydraulic rod, a support plate is symmetrically fixedly connected to the outer wall of the side of the paper cutting knife, a pressure rod is slidably connected to the inner wall of the support plate, a pressure plate is fixedly connected to the outer wall of the bottom of the pressure rod, and a pressure spring is fixedly connected to the outer wall of the pressure plate.

[0012] Preferably, the outer wall of the pressure spring on the side away from the pressure plate is fixedly connected to the outer wall of the bottom of the support plate, and the outer wall of the support plate is slidably connected to the inner wall of the side of the paper cutter. When the support plate moves downward, the pressure plate contacts the paper before the paper cutter and presses the paper. At the same time, the pressure rod slides upward along the support plate, and the pressure spring fixedly connected to the outer wall of the pressure plate is compressed. The downward pressure generated by the pressure spring allows the pressure plate to press the paper more stably.

[0013] Preferably, the outer wall of the top of the base is fixedly connected to the outer wall of the bottom of the paper cutter, and the positioning seat is located below the paper cutter. When the hydraulic rod is activated, its piston rod extends downward, driving the paper cutter fixedly connected to the bottom outer wall to move downward, thereby cutting the paper.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4. This utility model provides a technical solution: a paper cutting mechanism for a paper cutter with good positioning effect, including: a base 1, a paper cutting device 3 fixedly connected to the outer wall of the top of the base 1, and a positioning device 2, the outer wall of the top of the base 1 being fixedly connected to the outer wall of the bottom of the positioning device 2; the positioning device 2 includes a positioning seat 21, the outer wall of the top of the positioning seat 21 having a moving groove 22 and a positioning groove 23, the inner wall of the moving groove 22 being rotatably connected to a lead screw 24, the inner wall of the positioning groove 23 being rotatably connected to a bidirectional threaded rod 25, the outer wall of the lead screw 24 being threadedly connected to a push plate 26, the outer wall of the bidirectional threaded rod 25 being symmetrically threadedly connected to a positioning plate 27, the inner wall of the top of the positioning seat 21 being fixedly connected to a scale 28, the outer wall of the top of the positioning seat 21 being symmetrically fixedly connected to a connecting plate 29, the inner wall of the connecting plate 29 being fixedly connected to a slide rod 291, the outer wall of the slide rod 291 being slidably connected to a baffle 292, and the outer wall of the baffle 292 being symmetrically fixedly connected to a compression spring 293.

[0025] The outer wall of the push plate 26 is slidably connected to the inner wall of the moving groove 22. By rotating the lead screw 24, the rotation of the lead screw 24 will be converted into the linear movement of the push plate 26 along the axis of the lead screw 24 in the moving groove 22. The outer wall of the positioning plate 27 is slidably connected to the inner wall of the positioning groove 23. By rotating the bidirectional threaded rod 25, the rotation of the bidirectional threaded rod 25 will cause the two positioning plates 27 to move relative to each other along the inner wall of the positioning groove 23. The scale 28 is set below the push plate 26. The operator can adjust the position of the push plate 26 according to the scale 28 fixedly connected to the inner wall of the top of the positioning seat 21.

[0026] The connecting plate 29 is located on the side away from the push plate 26. The outer wall of the compression spring 293 on the side away from the baffle 292 is fixedly connected to the inner wall of the connecting plate 29. The outer wall of the bottom of the baffle 292 is slidably connected to the outer wall of the top of the positioning seat 21. When the paper squeezes the baffle 292, the baffle 292 slides along the slide rod 291 and compresses the compression spring 293 under the pushing force of the paper. The reaction force generated by the compression spring 293 will make the baffle 292 press tightly against the side of the paper.

[0027] The paper cutting device 3 includes a paper cutting frame 31. A hydraulic rod 32 is fixedly connected to the inner wall of the top of the paper cutting frame 31. A paper cutting knife 33 is fixedly connected to the outer wall of the bottom of the hydraulic rod 32. A support plate 35 is symmetrically fixedly connected to the outer wall of the side of the paper cutting knife 33. A pressure rod 36 is slidably connected to the inner wall of the support plate 35. A pressure plate 37 is fixedly connected to the outer wall of the bottom of the pressure rod 36. A pressure spring 38 is fixedly connected to the outer wall of the pressure plate 37.

[0028] The outer wall of the pressure spring 38 on the side away from the pressure plate 37 is fixedly connected to the outer wall of the bottom of the support plate 35. The outer wall of the support plate 35 is slidably connected to the inner wall of the side of the paper cutter 31. When the support plate 35 moves downward, the pressure plate 37 contacts the paper before the paper cutter 33 and presses the paper. At the same time, the pressure rod 36 slides upward along the support plate 35, and the pressure spring 38 fixedly connected to the outer wall of the pressure plate 37 is compressed. The downward pressure generated by the pressure spring 38 makes the pressure plate 37 press the paper more stably.

[0029] The outer wall of the top of the base 1 is fixedly connected to the outer wall of the bottom of the paper cutter 31. The positioning seat 21 is located below the paper cutter 31. When the hydraulic rod 32 is started, its piston rod extends downward, driving the paper cutter 33 fixedly connected to the bottom outer wall to move downward, thereby cutting the paper.

[0030] In use, the paper is placed on the positioning device 2, and the paper is positioned by the cooperation of the push plate 26, the positioning plate 27 and the baffle 292. Then the paper is cut by the paper cutting device 3.

[0031] First, the paper is placed on the positioning seat 21. By rotating the lead screw 24, since the lead screw 24 is threadedly connected to the push plate 26 and the outer wall of the push plate 26 is slidably connected to the inner wall of the moving groove 22, the rotation of the lead screw 24 will be converted into the linear movement of the push plate 26 along the axis of the lead screw 24 in the moving groove 22, so that the push plate 26 contacts the paper, thereby determining the position of one side of the paper. Then, the bidirectional threaded rod 25 is rotated. Since the outer wall of the bidirectional threaded rod 25 is symmetrically threaded with positioning plates 27 and the outer wall of the positioning plates 27 is slidably connected to the inner wall of the positioning groove 23, the rotation of the bidirectional threaded rod 25 will cause the two positioning plates 27 to move inward along the inner wall of the positioning groove 23. Thus, the distance between the two positioning plates 27 can be adjusted according to the width of the paper to ensure the accurate placement of the paper in the width direction, forming a preliminary positioning.

[0032] Next, continue to rotate the lead screw 24 to push the paper closer to the connecting plate 29, so that the paper contacts the outer wall of the baffle 292. The operator can adjust the position of the push plate 26 according to the scale 28 fixedly connected to the inner wall of the top of the positioning seat 21 to adjust the required cutting length. At this time, the paper will squeeze the baffle 292. Under the pushing force of the paper, the baffle 292 slides along the slide bar 291 and compresses the compression spring 293. The reaction force generated by the compression spring 293 will make the baffle 292 press tightly against the side of the paper, which plays a role in assisting in positioning the paper and preventing the paper from shifting to that side during the cutting process. This design can adapt to the positioning of different cutting surfaces without the need for the operator to manually use tools to press against the side of the paper.

[0033] The hydraulic rod 32, fixedly connected to the inner wall of the top of the paper cutter 31, provides the cutting power. When the hydraulic rod 32 is activated, its piston rod extends downward, driving the paper cutter 33, fixedly connected to the outer wall at the bottom, to move downward and cut the paper. During the downward movement of the paper cutter 33, the support plate 35, symmetrically fixedly connected to the outer wall of the side of the paper cutter 33, moves downward synchronously, so that the pressure plate 37 contacts the paper and presses it down before the paper cutter 33. At the same time, the pressure rod 36 slides upward along the support plate 35, and the pressure spring 38, fixedly connected to the outer wall of the pressure plate 37, is compressed. The downward pressure generated by the pressure spring 38 allows the pressure plate 37 to press the paper more stably, preventing the paper from shifting or wrinkling due to uneven force during the cutting process, thus ensuring the cutting quality. After the cutting is completed, the piston rod of the hydraulic rod 32 retracts, driving the paper cutter 33, support plate 35, and other components to rise and reset. The pressure rod 36 and pressure plate 37 also reset upward under the action of the pressure spring 38.
