Description

Technical Field

[0001] This utility model relates to the field of paper cutter technology, and in particular to a high-speed paper cutter. Background Technology

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to magnetic tape-controlled paper cutters, and further to microcomputer-controlled, color-display, fully image-guided visual processing, and computer-aided cutting systems with external programming and editing of production data. This has resulted in shorter production preparation time, higher cutting accuracy, lower labor intensity, and safer operation.

[0003] For example, the public announcement number CN220516918U discloses a high-speed paper cutter, which includes a table and a cutter. The bottom left and right sides of the table are provided with two support feet, and the top left and right sides of the table are provided with support plates. The top of the left support plate is provided with a horizontal plate that is fixedly connected to the top of the right support plate. A movable plate is provided between the two support plates. The top left and right sides of the horizontal plate are provided with hydraulic cylinders. This high-speed paper cutter uses a first servo motor to move the cutter left or right, a second servo motor to move it forward or backward, and a third servo motor to rotate it. This multi-range adjustment allows for multi-directional paper cutting without requiring manual adjustment of the paper's orientation, thus simplifying operation. However, by placing multiple components at the lower end of the hydraulic cylinder, the cylinder provides significant force during operation, compromising the cutter's stability. Furthermore, the need for multiple drive elements to achieve multi-directional paper cutting reduces the device's overall adaptability and practicality. Utility Model Content

[0022] Reference Figure 1-4 A high-speed paper cutter includes a base 1, a fixed frame 2 at the upper end of the base 1, a through groove 3 at the upper end of the fixed frame 2, a movable plate 7 in the through groove 3, a connecting plate 10 at the lower end of the movable plate 7, an mounting plate 11 at the lower end of the connecting plate 10, a cutter 12 at the lower end of the mounting plate 11, a connecting mechanism for connecting the connecting plate 10 on the movable plate 7, the connecting mechanism including a rotating groove 8 on the movable plate 7, a rotating plate 9 rotatably connected in the rotating groove 8, two symmetrically arranged telescopic cylinders 13 penetrating the rotating plate 9, and the telescopic connecting plate 10 being disposed at the telescopic ends of the two telescopic cylinders 13.

[0023] The through groove 3 is equipped with a moving mechanism for moving the moving plate 7. The moving mechanism includes two symmetrically arranged threaded rods 4 that are rotatably connected through the through groove 3 and the side wall of the fixed frame 2. Both threaded rods 4 pass through the moving plate 7 and are threadedly connected to it. By moving the moving plate 7 in the through groove 3, the moving plate 7 moves the cutter 12, so that the cutter 12 can be adjusted laterally according to the size of the paper, thereby improving the practicality of the device.

[0024] The upper end of the movable plate 7 is provided with a mounting frame, and the mounting frame is provided with a power motor 16. The outer wall of the output shaft of the power motor 16 is provided with a gear 15.

[0025] The upper end of the rotating plate 9 is provided with a toothed ring 14, which meshes with the gear 15. By causing the rotating plate 9 to rotate along with the telescopic cylinder 13 and the cutter 12, the cutter 12 rotates around the rotating plate 9 as the center, so that the position of the cutter 12 can be above any position of the paper, realizing multi-directional operation of the paper and improving the adaptability of the device.

[0026] Both threaded rods 4 have synchronous pulleys 5 on their outer walls. The two synchronous pulleys 5 are connected by a synchronous belt drive. The side wall of the fixed frame 2 has a support plate. The upper end of the support plate has a drive motor 6. One end of the threaded rod 4 is connected to the end of the output shaft of the drive motor 6.

[0027] When this utility model is used, during multi-directional paper cutting, the power motor 16 is started, causing the gear 15 on the outer wall of the output shaft of the power motor 16 to rotate. The meshing of the gear 15 with the gear ring 14 and the rotational connection between the rotating plate 9 and the rotating groove 8 cause the gear ring 14 to rotate, which in turn causes the rotating plate 9 to rotate, carrying the telescopic cylinder 13 and the cutter 12 to rotate. Thus, the cutter 12 rotates around the rotating plate 9 as the center, allowing the cutter 12 to be positioned above any position on the paper, achieving multi-directional paper cutting and improving the adaptability of the device.

[0028] Through the threaded connection between the movable plate 7 and the two threaded rods 4, and the transmission action of the synchronous pulley 5 and the synchronous belt between the two threaded rods 4, the drive motor 6 is started, causing the movable plate 7 to move in the through groove 3, thereby moving the movable plate 7 with the cutter 12. The cutter 12 can be adjusted laterally according to the size of the paper, thereby improving the practicality of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
