[0037] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0038] Example 1: This example provides a technical solution: a high-speed paper slitting machine, such as... Figures 1-11 As shown, the present invention includes a main control console 1, a frame 2, and two sets of winding frames 3.

[0039] In specific implementations, such as Figure 1As shown, the main control console 1 is equipped with a control panel 5, and the control panel 5 contains a controller to facilitate the control of various components.

[0040] In specific implementations, such as Figure 1 and Figure 2 As shown, the frame 2 is positioned on one side of the main control console 1, and space is left between the frame 2 and the main control console 1 for mounting components. Multiple guide rollers 6 are installed between the frame 2 and the main control console 1, and at least one slitting roller 7 is positioned between the frame 2 and the main control console 1. The slitting roller 7 is located behind the guide rollers 6. Figure 1 As shown, the guide roller 6 near the slitting roller 7 is below the slitting roller 7 in the horizontal direction. The main control panel 1 and the rear side of the frame 2 are both provided with mounting grooves 8, and the two ends of the slitting roller 7 are respectively locked in the mounting grooves 8 on both sides.

[0041] Furthermore, two sets of take-up frames 3 are respectively set on the front and rear sides of the frame 2. The take-up frame 3 on the front side of the frame 2 is a front take-up frame 3 for placing uncut paper, and the take-up frame 3 on the rear side of the frame 2 is a rear take-up frame 3 for taking up the cut paper. The take-up frame 3 includes a fixed base 301, a mounting side plate 302, a servo motor 303, and a rotating rod 304. The fixed base 301 is installed on the front side of the frame 2, the mounting side plate 302 is installed on the top of the fixed base 301, the servo motor 303 is installed on one side of the mounting side plate 302, and the rotating rod 304 is installed at the output end of the servo motor 303. The two rotating rods 304 are located on the front and rear sides of the guide roller 6, respectively. When the front take-up frame 3 releases paper and the rear take-up frame 3 takes up the cut paper, the rotating rod 304 is rotated by the servo motor 303. The servo motor 303 is connected to the controller for easy control via the control panel 5.

[0042] In specific implementations, such as Figures 1-7As shown, multiple sets of roller ring assemblies 9 for limiting and cutting the paper are fixedly installed on the rotating rod 304 of both the slitting roller 7 and the front winding frame 3. The roller ring assembly 9 consists of multiple roller rings 10 fixedly arranged in sequence. The roller rings 10 can be connected by adhesive or by using screws or other fasteners. The roller ring 10 has an inner ring groove 11. Three through grooves 12 are evenly opened between the inner ring groove 11 and the outer wall of the roller ring 10. The three through grooves 12 are respectively located at the top center and the bottom two sides of the roller ring 10. Limiting elements 13 are set in the through grooves 12. The limiting element 13 at the top of the roller ring 10 on the slitting roller 7 is a blade 1301. The paper passes through... The slitting roller 7 can be slit by the blade 1301. A magnetic control component 14 for controlling the position of the limiting member 13 is provided in the inner ring groove 11. The magnetic control component 14 can control whether the limiting member 13 inside or outside the roller ring 10, thus facilitating the limiting of both ends of the paper. Furthermore, the two roller rings 10 to be used can be flexibly selected according to the length of the paper tube, making it flexible and convenient to use. An opening is provided on one side of the roller ring 10, and an installation ring 15 is installed in the opening. The distance from the through groove 12 to the closed side of the roller ring 10 is the same as the wall thickness of the roller ring 10. Therefore, the limiting movement distance of the paper end is the same as the wall thickness of the roller ring 10. Figure 5 As shown, when the roller ring 10 is set, the two roller rings 10 are mirrored. The distance between the limiting member 13 in the innermost two roller rings 10 is equal to twice the thickness of the roller ring 10, thus ensuring that the limiting space is small.

[0043] Furthermore, such as Figure 8 and Figure 9As shown, the magnetic attraction control assembly 14 includes an electromagnetic block 1401, a mounting plate 1402, a limiting spring 1403, and a metal pusher block 1404. The mounting plate 1402 is mounted on the inner wall of the inner ring groove 11 via the limiting spring 1403. A limiting member 13 is mounted on the mounting plate 1402. Under normal conditions, the limiting spring 1403 can control the metal pusher block 1404 within the roller ring 10, thus allowing the limiting member 13 to be stored. The metal pusher block 1404 is a block-shaped structure with both sides narrowing and widening, and the surface of the widening section is arc-shaped. One side of the mounting plate 1402 contacts the arc-shaped surface. The narrower side of the metal pusher block 1404 is located below the mounting plate 1402, and the wider side of the metal pusher block 1404 is attached to the mounting ring 15. A guide rod 16 is installed between the inner wall of the inner ring groove 11 and the mounting ring 15. A guide hole 17 is opened on the metal pusher block 1404, and the guide rod 16 is engaged in the guide hole 17. 401 is installed on the inner wall of the inner ring groove 11, and the electromagnetic block 1401 corresponds to the metal push block 1404. The metal push block 1404 can be made of iron. The electromagnetic block 1401 is electrically connected to an external power supply or a power supply is set in the roller ring 10. The electromagnetic block 1401 is also connected to the controller for easy control via the control panel 5. When the limit member 13 needs to be moved out, the electromagnetic block 1401 in the roller ring 10 is activated. The electromagnetic block 1401 can generate magnetic attraction and attract the metal push block 1404 to move. The metal push block 1404 can be attracted by the magnetic force of the electromagnetic block 1401 and move in the direction of the electromagnetic block 1401. When moving, the metal push block 1404 can push the mounting plate 1402 and the limit member 13 upward through the arc surface. Therefore, the limit member 13 can be moved out of the roller ring 10. The limit members 13 on both sides can limit the paper to prevent significant displacement during the paper cutting process.

[0044] Furthermore, such as Figure 8 and Figure 10 As shown, the contact area between the mounting plate 1402 and the metal push block 1404 is arc-shaped, which ensures that the contact friction between the mounting plate 1402 and the metal push block 1404 is small, thus ensuring that the electromagnetic block 1401 can easily push the mounting plate 1402 upward when attracting the metal push block 1404 to move.

[0045] Furthermore, the metal push block 1404 has a hollow internal structure, which reduces its weight and ensures that it can move more easily and stably.

[0046] Furthermore, such as Figure 2 and Figure 11As shown, the bottom of the mounting groove 8 is provided with a placement groove, in which a hydraulic cylinder 20 is installed. A positioning block 21 is provided in the mounting groove 8. The positioning block 21 is installed at the output end of the hydraulic cylinder 20. The end of the slitting roller 7 is locked between the positioning block 21 and the inner wall of the mounting groove 8. The hydraulic cylinder 20 and the positioning block 21 can fix the slitting roller 7, and at the same time, it can be easily removed when the roller ring 10 is inserted or removed.

[0047] In specific implementation, paper with an initial length of 24cm is cut into 12cm pieces using one slitting roller 7 and two guide rollers 6. The guide roller 6 closest to the slitting roller 7 is positioned horizontally below the slitting roller 7, and the guide roller 6 closest to the slitting roller 7 is positioned 8-10 cm horizontally below the outer roller ring 10 of the slitting roller 7. This ensures that the paper can be properly placed on the outer roller ring 10 of the slitting roller 7 from above the guide roller 6, and the paper only contacts the blade 1301. The roller ring 10 is 2cm thick with a wall thickness of 0.3cm. Each set of roller rings 9 on the front take-up frame 3 contains 16 roller rings 10, which are evenly distributed in two mirrored sets. Each set of roller rings 9 on the take-up frame 3 contains 8 roller rings 10, which are evenly distributed in two mirror-like groups. Before processing, the uncut paper is placed on the front take-up frame 3, with the paper overlapping the outside of the roller rings 10. Then, the electromagnetic block 1401 inside the roller ring 10 that controls external proximity is activated. Therefore, the electromagnetic block 1401 can generate magnetic attraction and attract the metal push block 1404 to move. The metal push block 1404 can be attracted by the magnetic force of the electromagnetic block 1401 and move in the direction of the electromagnetic block 1401. When moving, the metal push block 1404 can push the mounting plate 1402 and the limiting member 13 upward through the arc surface. Therefore, the limiting member 13 can be moved out of the roller ring 10. The limiting members 13 on both sides can... To prevent significant displacement during paper slitting, the paper is positioned below the first guide roller 6, above the second guide roller 6, and above the slitting roller 7. The paper rests on one set of roller rings 9 on the slitting roller 7. Then, the electromagnetic block 1401 within the roller ring 10 at one end and the center edge of the paper is activated. This generates magnetic attraction, drawing the metal push block 1404 to move. The metal push block 1404 is attracted by the magnetic force of the electromagnetic block 1401 and moves towards it. During this movement, the metal push block 1404 pushes the mounting plate 1402 and the blade 1301 upwards via its curved surface. Therefore, the blade 1301... The paper can be moved out from inside the roller ring 10 without any operation on the other end of the complete paper. Only one of the slit papers is limited, and the other paper is automatically limited. Then, the slit paper is fixed on the rotating rod 304 on the rear winding frame 3. Driven by the servo motor 303, the paper can be wound up. During the winding process, the blade 1301 automatically cuts the paper. The two limiting parts 13 on the front winding and the two blades 1301 on the slitting roller 7 can limit the uncut paper and the cut paper at the same time, so as to ensure the stability of the paper throughout the slitting process. Under the control of the servo motor 303, the paper can be moved to perform slitting, thereby improving product quality.

[0048] Example 2 is a further optimization based on the above examples. The parts identical to the aforementioned technical solutions will not be repeated here. Furthermore, to better realize the present invention, the following configuration is specifically adopted:

[0049] In specific implementations, such as Figure 1 and Figure 2 A take-up rack 3 is also installed on the upper rear side of the frame 2. The take-up rack 3 on the upper rear side of the frame 2 is an upper take-up rack 3 used to take up the slit paper. The upper take-up rack 3 can easily separate and take up the slit paper, making it easy to quickly distinguish when cutting paper of different lengths.

[0050] Furthermore, both the lower front and lower rear portions of the main control panel 1 are equipped with end positioning components 18 for maintaining the vertical stability of the rotating rod 304. The end positioning components 18 include a mounting base 1801, a movable contact structure 1802, a fixing plate 1803, and an adjusting cylinder 1804. The mounting base 1801 is installed on the front and rear sides of the main control panel 1, the fixing plate 1803 is installed on the mounting base 1801, the movable contact structure 1802 includes a movable side plate 18021 and a connecting shaft 18022 installed on the movable side plate 18021, and the adjusting cylinder 1804 is installed on one side of the fixing plate 1803. The movable side plate 18021 is installed at the output end of the adjusting cylinder 1804. One end of the rotating rod 304 is provided with a snap-fit ​​groove 4, and the connecting shaft 18022 is snapped in the snap-fit ​​groove 4. During slitting, the adjusting cylinder 1804 can control the push to move the connecting shaft 18022 in the contact structure 1802 and the snap-fit ​​groove 4 at the end of the rotating rod 304. Therefore, the rotating rod 304 can be used stably and safely. When it is necessary to install or remove the paper tube, the adjusting cylinder 1804 can control the movement of the movable side plate 18021 and leave a little space between the movable side plate 18021 and the rotating shaft, so as to facilitate the insertion and removal of paper.

[0051] Furthermore, a movable contact structure 1802 is provided on the upper rear side of the main control console 1. The movable contact structure 1802 on the upper rear side of the main control console 1 is connected to the movable contact structure 1802 on the lower rear side of the main control console 1 through a linkage rod 19. Therefore, the movable contact structure 1802 in the upper winding frame 3 and the rear winding frame 3 can be moved simultaneously through the linkage rod 19.

[0052] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
