Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper production equipment technology, specifically a multi-layer paper cutter with a sorting structure. Background Technology
[0002] With the rapid development of the modern printing and packaging industry, the requirements for paper cutting equipment are increasing, especially when processing multi-layered paper. Ensuring cutting accuracy, improving cutting efficiency, and enhancing the stability and durability of the equipment have become the focus of industry attention. Traditional multi-layer paper cutters often result in uneven edges when cutting multi-layered paper due to friction between the papers, the elasticity of the paper itself, and the limitations of the equipment's precision. This affects the quality of subsequent processing. The paper finishing process is relatively weak, lacking an effective finishing device, which leads to unevenness in multi-layered paper before cutting, affecting cutting accuracy and finished product quality. Furthermore, the movement control of the cutting position is not precise enough, and the paper cutter may deviate during horizontal and vertical movement, making it difficult to meet the requirements of high-precision cutting. Utility Model Content

[0031] Multi-layer paper cutter with a sorting structure, such as Figures 1-3As shown, the device includes a paper-cutting worktable 10, a paper-cutting hydraulic cylinder 20 mounted on one side of the worktable 10, a pushing and sorting plate 40 for sorting multi-layered paper mounted on the top surface of the worktable 10, a crossbeam 30 mounted on the top of the hydraulic cylinder 20, and a movable paper-cutting seat 50 mounted on the bottom surface of the crossbeam 30. Guide grooves 11 are provided at the center of the top surface of the worktable 10 and the bottom surface of the crossbeam 30. A first servo motor 14 is mounted at the middle of one end of the worktable 10, and the output shaft of the first servo motor 14... A first lead screw 15 is coaxially connected; a second servo motor 31 is installed at one end of the cross frame 30, and a second lead screw 32 is coaxially installed on the output of the second servo motor 31; a first guide seat 41, which is adapted to the cross-sectional dimensions of the guide groove 11 and is slidably fitted, is installed at the bottom center of the push sorting plate 40, and the first guide seat 41 is threadedly connected to the first lead screw 15; a second guide seat 52, which is adapted to the cross-sectional dimensions of the guide groove 11 and is slidably fitted, is installed at the top center of the paper cutter 50, and the second guide seat 52 is connected to the second lead screw. The paper cutter 50 is connected by a 32-threaded connection. A paper cutter 51 is mounted at the bottom of the paper cutter 50. Powered by a hydraulic cylinder 20 mounted on the paper cutter table 10, it works in conjunction with the movable paper cutter 50 mounted on the bottom of the crossbeam 30 and the paper cutter 51 at the bottom of the paper cutter 50 to achieve precise cutting of multi-layered paper. Simultaneously, a pusher plate 40 mounted on the top surface of the paper cutter table 10 is threadedly connected to a first lead screw 15 via a first guide seat 41 mounted at its bottom center. Driven by a first servo motor 14, it can slide along the guide groove 11, effectively organizing multi-layered paper and ensuring neat cuts. Furthermore, a second servo motor 31 mounted at one end of the crossbeam 30 has a second lead screw 32 coaxially mounted on its output shaft, which is threadedly connected to a second guide seat 52 at the top center of the paper cutter 50. This allows the paper cutter 50 to slide along the guide groove 11, thereby adjusting the position of the paper cutter 51 to adapt to the cutting needs of different paper sizes. The overall structure is compact and reasonable. Through the coordinated action of various components, the cutting of multi-layered paper becomes more efficient and precise.
[0032] Furthermore, each of the four corners of the bottom of the paper cutting workbench 10 is equipped with a column 12, and a shock-absorbing pad 13 is coaxially installed at the bottom of the column 12. The column 12 makes the paper cutting workbench 10 more stable, while the shock-absorbing pad 13 can effectively absorb the vibration generated during the cutting process, reduce noise and mechanical wear, and improve the stability and service life of the equipment.
[0033] Specifically, limit baffles 16 are provided on the adjacent sides of the top surface of the paper cutting table 10, which can limit the range of movement of the paper during the cutting process, prevent the paper from being misaligned or slipping during cutting, and further improve cutting accuracy and safety.
[0034] It is worth noting that the cross-sections of the guide groove 11, the first guide seat 41, and the second guide seat 52 are all convex, which makes the fit between the guide seat and the guide groove tighter and more stable. This effectively prevents the guide seat from shifting or shaking during the sliding process, ensuring the precise movement of the pushing plate 40 and the paper cutter 50 and improving the cutting accuracy.
[0035] The piston rod of the paper-cutting hydraulic cylinder 20 is connected to the bottom end of the crossbeam 30, so that the paper-cutting hydraulic cylinder 20 can directly provide stable lifting power to the crossbeam 30 and the paper-cutting seat 50 on it, ensuring that the paper-cutting knife 51 can descend accurately and smoothly to perform the cutting operation.
[0036] In addition, the first guide seat 41 and the second guide seat 52 are respectively provided with threaded holes 42 that are adapted to the size of the first lead screw 15 and the second lead screw 32 and are threadedly connected, so that the guide seat can be firmly threadedly connected to the lead screw, ensuring that it can slide stably and accurately along the guide groove under the drive of the servo motor, further improving the cutting accuracy and the reliability of the equipment.
[0037] The working principle of this multi-layer paper cutter with a sorting structure:
[0038] First, place the multi-layered paper on the paper cutting workbench 10 and use the limiting baffles 16 on the adjacent sides to initially limit the paper.
[0039] Next, the first servo motor 14 is started, and its output shaft drives the first lead screw 15 to rotate. Since the first guide seat 41 is threadedly connected to the first lead screw 15 and slides in the guide groove 11, it pushes the sorting plate 40 to move along the guide groove 11 to sort the paper. After the sorting is completed, the first servo motor 14 stops working.
[0040] Then, according to the cutting requirements, the paper cutting hydraulic cylinder 20 is activated, and its piston rod drives the crossbeam 30 to rise and fall to a suitable height;
[0041] Then, the second servo motor 31 is started. The output shaft of the second servo motor 31 drives the second lead screw 32 to rotate. The second guide seat 52 is threadedly connected to the second lead screw 32 and slides in the guide groove 11, thereby driving the paper cutter 50 and the paper cutter 51 at the bottom to move along the crossbeam 30 to cut the arranged paper.
[0042] During the cutting process, the column 12 and shock-absorbing pad 13 at the bottom of the paper cutting workbench 10 can reduce machine vibration; after the cutting is completed, the second servo motor 31 and the paper cutting hydraulic cylinder 20 are turned off, the cut paper is removed, and one paper cutting operation is completed.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
