Description
Technical Field
[0001] This utility model relates to the field of paper roll processing technology, and in particular to a paper roll slitting device with a correction function. Background Technology
[0002] The production process of paper rolls mainly includes several stages: log processing, pulping, papermaking, rewinding, packaging, and cutting. First, the logs are cut into appropriate lengths, then the bark and impurities are removed to ensure the purity of the pulp. The debarked logs are then fed into a chipper to be cut into small pieces. The wood fibers are then separated through cooking and chemical treatment to make pulp. The pulp is then evenly spread on the wire section of the paper machine and filtered through a screen to interweave the fibers and form a wet sheet. After drying, the paper is rewound into rolls of a certain width and diameter by a rewinder for subsequent processing. Finally, the rolls are slit.
[0003] Paper roll slitting is a crucial process in the papermaking industry, and its precision directly affects the quality and performance of paper roll products. As the packaging industry increases its requirements for paper roll slitting precision, traditional slitting devices, lacking effective deviation correction functions, frequently cause problems such as uneven edges and inconsistent widths of the slitting paper rolls. Currently, the industry mainly reduces deviations by manually adjusting and adding auxiliary guiding devices. In recent years, automated deviation correction technology has been gradually applied to slitting equipment, but the former is difficult to meet the needs of high-speed slitting, while the latter has a complex structure and high cost, limiting its adoption in small and medium-sized enterprises, resulting in reduced production efficiency and increased production costs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a roll paper slitting device with a correction function, which aims to improve the problem that the correction structure in the existing roll paper slitting device is difficult to meet the requirements of high-speed slitting, and the high cost leads to reduced production efficiency and increased production costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a roll paper slitting device with a correction function, comprising an unwinding frame, a support fixedly connected to the bottom of the unwinding frame, a platform fixedly connected to the right side of the unwinding frame, an asynchronous motor fixedly connected to an adjacent side of the support, a positioning shaft fixedly connected to the output end of the asynchronous motor, a mounting frame fixedly connected to the right side of the platform, a parallel rod fixedly connected to the inner wall of the mounting frame, a moving block provided on the outer wall of the parallel rod, a plurality of second rotating shafts rotatably connected to the rear side of the moving block, a plurality of telescopic rods fixedly connected to the front side of the moving block, a first rotating rod rotatably connected to the outer wall of the second rotating shaft, a second rotating rod rotatably connected to the outer wall of the first rotating rod, a correction clamp rotatably connected to the outer wall of the second rotating rod, a plurality of limit screws threaded between adjacent first and second rotating rods, and a plurality of disassembly and adjustment mechanisms provided in the middle of the inner wall of the mounting frame, the disassembly and adjustment mechanisms being used to disassemble and replace the internal structure of the device.
[0006] Through the above technical solutions: the pallet can not only temporarily store the rolls of paper to be cut, but also act as a buffer during the transfer of the rolls to prevent damage to the surface of the rolls. The parallel rod is used to provide guidance for the sliding of the moving block. The limit screw can limit the first rotating rod and the second rotating rod after the angle is adjusted to ensure the stability of the entire structure. The disassembly and adjustment mechanism allows the operator to quickly disassemble and replace the corresponding parts when a certain part of the device is worn or damaged, or when it is necessary to adjust according to the existing materials.

A guide roller shaft is fixedly connected to the outer wall of the first rotating shaft. A mounting block is rotatably connected to the front end of the first rotating shaft. A through groove is provided in the inner wall of the sliding groove. A limit rod is slidably connected to the inner wall of the through groove. A limit plate is fixedly connected to the top of the limit rod.
[0009] With the above technical solution: when it is necessary to disassemble components such as guide roller shafts, the operator first holds the limiting plate and slides the limiting rod upward along the through groove, so that it is freed from the limiting effect of the mounting block. The mounting block can guide the first rotating shaft and the guide roller shaft fixed on its outer wall into the slide groove, thereby limiting the entire structure through the limiting mounting block.
[0010] As a further description of the above technical solution:
[0011] The bottom of the limiting plate is fixedly connected with an anti-slip pad, and the inner wall of the limiting plate is threaded with reinforcing screws.
[0012] Through the above technical solution, the anti-slip pad can increase the friction at the bottom of the limiting plate.
[0013] As a further description of the above technical solution:

[0021] The above technical solution uses a guide block to guide the cutter to slide within it.
[0022] As a further description of the above technical solution:
[0023] The top of the platform has multiple anti-slip textures, and multiple baffles are fixedly connected to the top of the platform near the edge. A controller is fixedly connected to the left side of the mounting frame near the edge.
[0024] Through the above technical solution, the anti-slip texture can increase the friction on the top of the platform.
[0025] As a further description of the above technical solution:
[0026] A rubber pad is fixedly connected to the inner wall of the correction clamp, and a washer is provided on the outer wall of the limiting screw.
[0027] Through the above technical solution, the rubber pad can buffer the friction and collision between the alignment clip and the paper.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, by starting an asynchronous motor, the paper roll between adjacent positioning shafts is driven so that it can be processed along the transmission roller shaft and reach the parallel rod. Then, it passes through the inner wall of the correction clamp to reach the final processing position. When the paper roll deviates, it will trigger the telescopic rod to push the moving block, which in turn pushes the correction clamp to correct the paper.

Detailed Implementation
[0040] 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.
[0041] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a paper roll slitting device with a correction function, including a roll unwinding frame 1, which is a movable structure for supporting the paper roll. A support 6 is fixedly connected to the bottom of the roll unwinding frame 1, and a platform plate 5 is fixedly connected to the right side of the roll unwinding frame 1. The platform plate 5 is a structure for connecting the two sides. An asynchronous motor 3 is fixedly connected to an adjacent side of the support 6, and a positioning shaft 4 is fixedly connected to the output end of the asynchronous motor 3. A mounting frame 7 is fixedly connected to the right side of the platform plate 5, and a parallel rod 9 is fixedly connected to the inner wall of the mounting frame 7. The support 6 is used to support the mounting of the asynchronous motor 3. A moving block 16 is provided on the outer wall of the parallel rod 9, and multiple second rotating shafts 12 are rotatably connected to the rear side of the moving block 16. The front of the moving block 16... Multiple telescopic rods 8 are fixedly connected to the side. The mounting frame 7 can provide support for the installation of other structures. The outer wall of the second rotating shaft 12 is rotatably connected to the first rotating rod 11. The outer wall of the first rotating rod 11 is rotatably connected to the second rotating rod 13. The outer wall of the second rotating rod 13 is rotatably connected to the correction clamp 10. The telescopic rods 8 can push the moving block 16 to slide. Multiple limit screws 15 are threaded between adjacent first rotating rods 11 and second rotating rods 13. Both first rotating rods 11 and second rotating rods 13 are used to support the correction clamp 10. Multiple disassembly and adjustment mechanisms 2 are provided in the middle of the inner wall of the mounting frame 7. The disassembly and adjustment mechanisms 2 are used to disassemble and replace the structure inside the device. The correction clamp 10 can correct the position of the paper roll.
[0042] Specifically, the brackets 6 are symmetrically distributed to support the entire equipment, ensuring its stability during operation and preventing slitting of the paper rolls due to shaking. The pallet 5 provides a stable transition platform for subsequent slitting processes. The positioning shaft 4 controls the unwinding speed and tension of the paper rolls, ensuring smooth paper roll transport. By turning the limit screw 15, the relative position and angle of the first rotating rod 11 and the second rotating rod 13 can be adjusted, thereby achieving fine-tuning of the position and posture of the correction clamp 10 to adapt to paper rolls of different specifications and conditions.
[0043] Please see the appendix Figure 4 - Appendix Figure 6 The disassembly and adjustment mechanism 2 includes a rotating groove 201, which is located in the middle of the inner wall of the mounting frame 7. The inner wall of the mounting frame 7 is provided with multiple sliding grooves 205 near the edge. Both the rotating groove 201 and the sliding grooves 205 are used to provide guidance for the installation of other structures. The inner wall of the rotating groove 201 is rotatably connected to a first rotating shaft 202. The outer wall of the first rotating shaft 202 is fixedly connected to a guide roller shaft 203. The front end of the first rotating shaft 202 is rotatably connected to a mounting block 204. The first rotating shaft 202 is used to drive the guide roller shaft 203 to rotate together. The inner wall of the sliding groove 205 is provided with a through groove 206. The inner wall of the through groove 206 is slidably connected to a limit rod 208. The top of the limit rod 208 is fixedly connected to a limit plate 207. The limit plate 207 is used to limit the position of the limit rod 208.
[0044] Specifically, the chute 205 ensures smooth sliding of the components and effectively reduces frictional loss, extending the service life of the mechanism. The guide roller 203 plays a guiding role in the paper roll slitting process, ensuring that the paper roll is transported smoothly along the predetermined path. The through groove 206 and the chute 205 are perpendicularly connected to each other, forming a T-shaped structure. The limiting plate 207 is a rectangular plate structure, slightly larger than the opening of the through groove 206, which prevents the limiting rod 208 from falling out of the through groove 206. The limiting rod 208 can limit the sliding of the mounting block 204 in the chute 205, thereby ensuring that the entire device can maintain stability during operation.
[0045] Please see the appendix Figure 5 - Appendix Figure 7 A cutting table 21 is fixedly connected to the right side of the mounting frame 7, and a display screen 17 is fixedly connected to the left side of the mounting frame 7. The cutting table 21 is used to support the cutting of paper. An anti-slip pad 27 is fixedly connected to the bottom of the limiting plate 207. A reinforcing screw 28 is threadedly connected to the inner wall of the limiting plate 207. The anti-slip pad 27 can increase the friction at the bottom of the limiting plate 207. Multiple transmission rollers 24 are rotatably connected to the inner wall of the unwinding frame 1, and multiple limiting rollers 25 are rotatably connected to the middle of the inner wall of the unwinding frame 1. Both the transmission rollers 24 and the limiting rollers 25 are used to guide the movement of paper.
[0046] Specifically, operators can view various parameters in real time on the display screen 17. The anti-slip pad 27 further enhances the stability of the mechanism and increases the friction between the limit plate 207 and the mounting frame 7, preventing the limit plate 207 from sliding during operation. The reinforcing screw 28 can more firmly connect the limit plate 207 and the mounting frame 7, further improving the stability of the limit mechanism and preventing the limit plate 207 from loosening due to vibration and other factors during equipment operation.
[0047] Please see the appendix Figure 2 - Appendix Figure 4 Multiple guide blocks 22 are fixedly connected to the right side of the cutting table 21. A cutter 23 is slidably connected between adjacent guide blocks 22. The guide blocks 22 are used to guide the cutter 23 to move back and forth within them, thereby cutting the paper. A rubber pad 26 is fixedly connected to the inner wall of the correction clamp 10. A washer 14 is provided on the outer wall of the limit screw 15. Multiple anti-slip textures 19 are provided on the top of the platform 5. The rubber pad 26 can buffer the inner wall of the correction clamp 10 and the paper. Multiple baffles 20 are fixedly connected to the top of the platform 5 near the edge. A controller 18 is fixedly connected to the left side of the mounting frame 7 near the edge. The controller 18 is used to help the user control the start and stop of the entire device.
[0048] Specifically, the rubber pad 26 increases the friction with the paper while avoiding damage to the paper surface. The rubber pad 26 can effectively buffer the pressure of the web guiding clamp 10 on the paper, preventing the paper from deforming and breaking due to excessive limiting force. At the same time, the good elasticity of the rubber pad 26 can also adapt to rolls of paper of different thicknesses and materials, enhancing the versatility of the web guiding clamp 10. The pad 14 can also prevent the limiting screw 15 from loosening due to vibration during equipment operation, further enhancing the stability of the web guiding mechanism and ensuring that the web guiding clamp 10 always maintains an accurate working position during the slitting process.
[0049] Working principle: When cutting the roll paper, the roll is first placed between the adjacent positioning shafts 4. Then, the asynchronous motor 3 is started, so that the roll paper can be positioned by the transmission roller shaft 24, processed by the structure on the limiting roller shaft 25, and then reach the parallel rod 9 through the platform plate 5. Then, it can pass through multiple correction clamps 10 to enter the next step. When the roll paper deviates, the telescopic rod 8 is activated to push the moving block 16 to slide back and forth on the outer wall of the parallel rod 9, thereby pushing the roll paper to move back and forth through the correction clamps 10 to return to the correct position. At the same time, the angle between the correction clamps 10, the second rotating rod 13 and the first rotating rod 11 can be adjusted by turning the limiting screw 15.
[0050] When the position of the guide roller shaft 203 needs to be adjusted according to different materials, first turn the reinforcing screw 28 to unscrew it from the limiting plate 207, and then pull the limiting rod 208 out of the through groove 206, so that the mounting block 204 can slide out of the slide groove 205 and then be taken out of the rotating groove 201 via the first rotating shaft 202. When installing, first insert the first rotating shaft 202 into the rotating groove 201, and then push the mounting block 204 so that it can enter the slide groove 205 until it reaches the right side of the through groove 206. Then insert the limiting rod 208 along the through groove 206 so that its outer wall fits against the outer wall of the mounting block 204, and limit the final position of the limiting rod 208 by the limiting plate 207.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
