Abstract
Description
Technical Field
[0001] This invention relates to the field of graded printing technology, specifically to a mechanical fine-tuning device for correcting lateral deviation of roll material in graded printing equipment. Background Technology
[0002] The mechanical fine-tuning device for lateral deviation of roll materials is a specialized mechanical adjustment device designed to address lateral deviation issues during roll material transport, adaptable to various grading printing production lines. It solves the problem of lateral deviation caused by equipment vibration, uneven roll material tension, and roller parallelism deviation in the unwinding, transport, and printing processes of paper, film, and non-woven fabric roll materials, ensuring the accuracy and stability of roll material feeding during grading printing. This device uses a detection component to capture the positional deviation signal of the roll material edge in real time, converting the signal into mechanical transmission action. Through a transmission structure such as lead screws, gears, and connecting rods, it drives the correction rollers to make minute lateral displacements, achieving instant correction of the roll material feeding path. The adjustment precision can adapt to the fine process requirements of grading printing.
[0003] Chinese patent application CN103217875A discloses a PCB exposure machine and its correction mechanism. It primarily addresses the problems of poor stability and low accuracy in existing correction mechanisms. The device includes a motor, an eccentric shaft, a first bearing, a second bearing, a bearing sleeve, and a tension spring. The eccentric shaft is located at the output end of the motor. The first and second bearings are sleeved on the eccentric shaft. Additionally, push plates are connected to the X-axis moving mechanism, the Y-axis moving mechanism, and the rotating arm. The first bearing is press-fitted with the push plate, and the bearing is sleeved outside the second bearing. One end of the tension spring is connected to the push plate, and the other end is connected to the bearing sleeve. The eccentric shaft drives the bearings to form a rolling fit with the push plate, achieving press-fitting. Rolling friction replaces sliding friction. Furthermore, the outer roundness of the precision bearing is more guaranteed than that of the eccentric shaft, and the stretching length no longer changes, resulting in high stability and good performance.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0023] This invention provides, through improvements, a mechanical fine-tuning device for correcting lateral deviation of roll material in a grading printing equipment, such as... Figures 1-11 As shown, including; The operating table 1 includes a detection component 102; the detection component 102 is used to detect the offset range of the material to be wound. The first correction mechanism 2 is set on the operating table 1 and is used to drive the winding drum to move in order to correct the deviation of the winding material. The second correction mechanism 3 is set on the operating table 1 and is used to drive the winding material to move in order to correct the deviation of the winding material.
[0024] In this device, the control panel 1 serves as the installation and control foundation for the entire device. It integrates a detection component 102, which is arranged according to the conveying path of the material to be wound. It can capture the lateral offset direction and offset range of the material to be wound in real time during the conveying and winding process, providing accurate signal basis for subsequent correction actions.
[0025] The first correction mechanism 2 is fixedly installed at the winding end of the operating table 1. It works in conjunction with the winding drum to receive the offset signal from the detection component 102 and perform corresponding actions. By driving the winding drum to make precise lateral displacement, it adjusts the spatial position of the winding drum and corrects the problem of material offset caused by winding drum installation deviation, uneven force, etc., so that the central axis of the winding drum is aligned with the feed reference axis of the material to be wound.
[0026] The second correction mechanism 3 is located on the operating table 1 near the material to be wound between the detection component 102 and the first correction mechanism 2 on the material to be wound. It is in direct contact with the material to be wound and can synchronously receive the offset signal from the detection component 102. By driving the material to be wound to make a lateral movement opposite to the offset direction, it directly corrects the offset caused by tension fluctuations, roller deviations, etc. during the conveying process, so that the material is conveyed to the winding drum along the reference path.
[0027] The first correction mechanism 2 and the second correction mechanism 3 work together to achieve synchronous correction of the position of the take-up drum and the material feeding path. This dual correction of the lateral deviation of the roll material from both the take-up end and the material conveying end effectively avoids secondary deviation caused by single correction and improves the neatness of the roll material and the printing accuracy during the grading printing process.
[0028] See appendix Figure 3 -Appendix Figure 4 The first correction mechanism 2 includes two support plates 201 fixedly mounted on the operating table 1, and a motion plate 202 slidably mounted between the two support plates 201; the motion plate 202 is used to drive the winding drum to move; the motion plate 202 is also provided with a clamping assembly, which is used to fix the winding drum.
[0029] In this embodiment: the mechanism relies on two support plates 201 fixed on the operating table 1 to form a basic installation and guide support structure. The two support plates 201 are arranged in parallel to each other to provide stable guidance and limit for the lateral sliding of the moving plate 202, ensuring the straightness of the moving plate 202 during the movement process and avoiding deviation from affecting the correction accuracy.
[0030] In this embodiment, the motion plate 202 is slidably fitted between the two support plates 201. As the direct bearing and moving component of the winding drum, it is the core execution structure for realizing the adjustment of the winding drum position. It can make precise lateral linear movement along the support plate 201, thereby driving the winding drum installed on it to synchronously complete the corresponding amplitude of position adjustment, so as to match the feeding position of the material to be wound and correct the material offset problem caused by the position deviation of the winding end.
[0031] In this embodiment, the clamping assembly provided on the motion plate 202 can firmly and stably clamp and fix the inner cylinder of the winding drum, adapt to the installation requirements of winding drums of different specifications, ensure the connection stability between the winding drum and the motion plate 202, avoid the winding drum from becoming loose, slipping or having coaxiality deviation during the movement of the motion plate 202, and ensure the synchronization and accuracy of the winding drum moving with the motion plate 202.
[0032] Meanwhile, during the winding process, the clamping assembly effectively restricts the radial and axial movement of the winding drum, providing structural protection for stable winding and precise correction. When the detection assembly 102 detects a lateral shift in the material to be wound, the moving plate 202 slides laterally along the support plate 201 in the corresponding direction and amplitude. The clamping assembly drives the winding drum to move synchronously until the central axis of the winding drum is aligned with the feed reference axis of the material to be wound, completing the position correction of the winding end. This, combined with the second correction mechanism 3, achieves synchronous correction of the winding drum and the material to be wound.
[0033] See appendix Figure 3 -Appendix Figure 4 The first correction mechanism 2 includes a first motor 203, and a screw 204 is provided at the output end of the first motor 203. The moving plate 202 is threadedly connected to the screw 204. The first motor 203 is used to drive the moving plate 202 to slide relative to the two support plates 201, thereby driving the winding drum to move.
[0034] In this embodiment: the first correction mechanism 2 uses the first motor 203 as the power source and relies on the screw 204 transmission structure to realize precise lateral displacement adjustment of the winding drum, providing power and transmission support for correction at the winding end.
[0035] The first motor 203 is fixedly installed, and its output end is coaxially connected to the screw 204, which can drive the screw 204 to rotate in both directions. The screw 204 cooperates with the two support plates 201 to achieve stable support, and at the same time forms a threaded connection with the moving plate 202.
[0036] In this embodiment: when the detection component 102 detects a lateral offset in the material to be wound and transmits a correction signal, the first motor 203 starts and rotates in the corresponding forward and reverse directions according to the offset direction and amount, driving the screw 204 to rotate synchronously. By utilizing the threaded transmission between the screw 204 and the moving plate 202, the rotational motion of the screw 204 is converted into the lateral linear sliding of the moving plate 202 along the two support plates 201. The sliding direction and sliding distance of the moving plate 202 are precisely controlled by the rotation direction and number of rotations of the first motor 203.
[0037] In this embodiment: During the sliding process, the motion plate 202 drives the take-up drum fixed by the clamping component to move laterally in sync, so as to achieve precise adjustment of the position of the take-up drum and keep the central axis of the take-up drum aligned with the feed reference axis of the material to be taken up, thereby correcting the material offset problem caused by the position deviation of the take-up drum at the take-up end. It forms a synchronous linkage with the second correction mechanism 3 to ensure the accuracy and timeliness of the overall correction.
[0038] See appendix Figure 3 -Appendix Figure 5 A first linkage wheel 209 and a second linkage wheel 212 are rotatably mounted on the motion plate 202; a linkage rod 205 is rotatably mounted between the two support plates 201; a through cavity 210 is opened in the middle of the first linkage wheel 209; the linkage rod 205 passes through the first linkage wheel 209 and is connected to it for transmission; multiple locking blocks 211 are spaced apart on the inner wall of the cavity 210; multiple slots 206 are opened on the outer wall of the linkage rod 205, corresponding to the multiple locking blocks 211; the locking blocks 211 are slidably mounted in the slots 206; when the linkage rod 205 rotates, the first linkage wheel 209 drives the second linkage wheel 212 to rotate and wind up the winding material.
[0039] In this embodiment: the first correction mechanism 2 relies on the linkage transmission structure to realize the transmission of winding power and the continuous transmission of power when the winding drum moves with the moving plate 202, and at the same time completes the material winding action.
[0040] In this embodiment: the first linkage wheel 209 and the second linkage wheel 212, which are rotatably arranged on the motion plate 202, form a linkage cooperation to provide transmission support for the winding action. The linkage rod 205, which is rotatably arranged between the two support plates 201, serves as an external power input component and provides rotational power for the overall linkage structure. The first linkage wheel 209 has a through cavity 210 in the middle. The linkage rod 205 passes through the cavity 210 to achieve a transmission connection with the first linkage wheel 209. The inner wall of the cavity 210 has multiple locking blocks 211 spaced apart, which correspond one-to-one with the multiple slots 206 opened on the outer wall of the linkage rod 205. The locking blocks 211 slide in the corresponding slots 206. This structure not only realizes the circumferential transmission limit between the linkage rod 205 and the first linkage wheel 209, but also retains the relative sliding space between the two along the axial direction.
[0041] In this embodiment: when the external power drives the linkage rod 205 to rotate, the rotational power of the linkage rod 205 is directly transmitted to the first linkage wheel 209 through the circumferential engagement of the locking block 211 and the locking slot 206, causing the first linkage wheel 209 to rotate synchronously. The first linkage wheel 209 then drives the cooperating second linkage wheel 212 to rotate synchronously. Through the transmission cooperation between the second linkage wheel 212 and the winding drum, the rotational power is transmitted to the winding drum, causing the winding drum to rotate to realize the winding operation of the material to be wound.
[0042] In this embodiment: when the detection component 102 detects material deviation, and the first motor 203 drives the motion plate 202 to slide laterally along the support plate 201, the motion plate 202 drives the first linkage wheel 209 and the second linkage wheel 212 to move laterally in sync. At this time, the locking block 211 in the cavity 210 of the first linkage wheel 209 will slide axially along the slot 206 on the outer wall of the linkage rod 205. This does not affect the circumferential power transmission between the linkage rod 205 and the first linkage wheel 209, and can adapt to the lateral movement of the motion plate 202. This ensures that the continuous transmission of winding power and the uninterrupted winding action are carried out during the process of the motion plate 202 driving the winding drum to correct its position, thereby realizing the synchronous development of position correction and material winding.
[0043] See appendix Figure 5 The first correction mechanism 2 also includes a second motor 207; the output end of the second motor 207 is connected to a first belt 208, and the first belt 208 is connected to a linkage rod 205; a second belt 213 is wound between the first linkage wheel 209 and the second linkage wheel 212, and the first linkage wheel 209 is connected to the second linkage wheel 212 through the second belt 213.
[0044] In this embodiment: the first correction mechanism 2 uses the second motor 207 as the power source for the winding action, providing continuous rotational power for the entire linkage winding structure. The output end of the second motor 207 is connected to the first belt 208, and the first belt 208 is in transmission cooperation with the linkage rod 205 between the two support plates 201 to form the first stage power transmission path.
[0045] When the second motor 207 starts rotating, power is synchronously transmitted to the linkage rod 205 via the first belt 208, causing the linkage rod 205 to rotate in the same direction. The linkage rod 205 passes through the cavity 210 of the first linkage wheel 209 on the motion plate 202. The locking block 211 on the inner wall of the cavity 210 slides and engages in the slot 206 on the outer wall of the linkage rod 205. This structure realizes the circumferential power transmission between the linkage rod 205 and the first linkage wheel 209, while retaining the axial relative sliding space between the two. Therefore, when the linkage rod 205 rotates, it can directly drive the first linkage wheel 209 to rotate synchronously, forming a second stage of power transmission.
[0046] In this embodiment: a second belt 213 is wound between the first linkage wheel 209 and the second linkage wheel 212 on the motion plate 202. The two form a third-stage synchronous transmission through the second belt 213. The rotational power of the first linkage wheel 209 is transmitted to the second linkage wheel 212 through the second belt 213, causing the second linkage wheel 212 to rotate synchronously. The second linkage wheel 212 then forms a transmission cooperation with the take-up drum, transmitting the rotational power to the take-up drum and driving the take-up drum to rotate to complete the winding operation of the material to be wound.
[0047] Meanwhile, when the first motor 203 drives the motion plate 202 to slide laterally along the support plate 201 for correction, the motion plate 202 will drive the first linkage wheel 209 and the second linkage wheel 212 to move laterally synchronously. At this time, the locking block 211 in the cavity 210 of the first linkage wheel 209 slides axially along the slot 206 of the linkage rod 205. This does not affect the power transmission between the linkage rod 205 and the first linkage wheel 209, nor does it change the transmission relationship between the first belt 208 and the second belt 213. This ensures that during the process of the motion plate 202 driving the winding drum to correct laterally, the winding power output by the second motor 207 can be continuously and stably transmitted to the winding drum through the multi-stage belt and linkage structure.
[0048] See appendix Figure 6 -Appendix Figure 7 The clamping assembly includes a fixed post 214 located on the axial outer wall of the second linkage wheel 212, and a moving post 218 slidably disposed inside the fixed post 214; a plurality of clamping arc plates 221 are slidably disposed on the axial outer wall of the second linkage wheel 212. When the moving post 218 slides relative to the fixed post 214, the moving post 218 drives the plurality of clamping arc plates 221 to clamp the winding drum.
[0049] In this embodiment, the clamping assembly uses the axial outer wall of the second linkage wheel 212 as the mounting base. Through the linkage of the fixed pile 214, the moving pile 218 and multiple clamping arc plates 221, it can quickly clamp and firmly fix the winding drum, and adapt to the coaxial rotation requirements of the winding drum.
[0050] The fixed pile 214 is fixed to the axial outer wall of the second linkage wheel 212. Its interior is a hollow structure. The moving pile 218 forms a sliding fit with the fixed pile 214 and can slide back and forth along the axial direction of the fixed pile 214. It is the actuator that drives the clamping action.
[0051] In this embodiment, multiple clamping arc plates 221 are distributed in a circumferential shape on the axial outer wall of the second linkage wheel 212, and all of them form a sliding fit with the second linkage wheel 212. They can move radially closer to or away from the axis of the second linkage wheel 212. The inner side wall of the clamping arc plate 221 is adapted to the outer wall curvature of the winding drum to ensure the clamping fit.
[0052] When it is necessary to fix the take-up drum, the moving pile 218 is pushed to slide axially relative to the fixed pile 214. During the sliding process, the moving pile 218 generates a radial thrust on multiple clamping arc plates 221, driving the multiple clamping arc plates 221 to slide synchronously along the outer wall of the second linkage wheel 212 towards the axis until the inner sidewall of all clamping arc plates 221 is tightly attached to the outer wall of the end of the take-up drum. Through the radial clamping force at multiple points, the take-up drum is firmly fixed at the axial position of the second linkage wheel 212, ensuring the coaxiality of the take-up drum and the second linkage wheel 212, and avoiding radial movement during the winding process.
[0053] In this embodiment: when it is necessary to disassemble the take-up drum, the moving pile 218 is pulled in the opposite direction to reset it relative to the fixed pile 214. The thrust of the moving pile 218 on the clamping arc plate 221 disappears, and the multiple clamping arc plates 221 slide synchronously away from the axis along the outer wall of the second linkage wheel 212, releasing the clamping limit on the take-up drum and realizing the rapid disassembly of the take-up drum.
[0054] At the same time, the clamping component rotates synchronously with the second linkage wheel 212. While completing the fixing of the take-up drum, it does not affect the transmission of rotational power from the second linkage wheel 212 to the take-up drum, ensuring the normal operation of the take-up action. Moreover, the overall clamping and unlocking action is simple to operate, and the take-up drum can be quickly replaced and fixed, which is suitable for the continuous operation requirements of the grading printing production line.
[0055] See appendix Figure 6 -Appendix Figure 8The fixed pile 214 has a cavity 220 inside, and the moving pile 218 is slidably disposed in the cavity 220; a first cylinder 217 is installed on the second linkage wheel 212, and the moving pile 218 is located at the output end of the first cylinder 217; multiple slots 215 communicating with the cavity 220 are provided on the outer wall of the fixed pile 214, and multiple first wedges 219 are provided on the outer wall of the moving pile 218, and the first wedges 219 are slidably disposed in the slots 215.
[0056] In this embodiment: the clamping assembly uses the first cylinder 217 as the power source and achieves radial linkage clamping of the clamping arc plate 221 through wedge block transmission and slotted guidance 215.
[0057] The cavity 220 inside the fixed pile 214 provides axial sliding space for the moving pile 218. The moving pile 218 slides within the cavity 220 and is connected to the output end of the first cylinder 217 fixed on the second linkage wheel 212. The first cylinder 217 provides power support for the axial sliding of the moving pile 218.
[0058] In this embodiment: multiple slots 215 on the outer wall of the fixed pile 214 are connected to the cavity 220. Multiple first wedges 219 fixed on the outer wall of the moving pile 218 are slidably fitted in each slot 215. The slots 215 provide sliding guidance for the first wedges 219 and restrict the first wedges 219 from rotating circumferentially with the moving pile 218, ensuring that the first wedges 219 can only make axial and radial linkage movements along the slots 215.
[0059] When it is necessary to clamp the take-up drum, the first cylinder 217 is activated and pushes the moving pile 218 at the output end to slide axially along the cavity 220 of the fixed pile 214. The moving pile 218 simultaneously drives multiple first wedges 219 on the outer wall to slide in the same direction along the corresponding slots 215. With the help of its own wedge structure, the first wedge 219 forms a radial thrust on the outer clamping arc plate 221 during the axial sliding process, driving multiple clamping arc plates 221 to move synchronously towards the take-up drum until they are tightly attached to the outer wall of the take-up drum to complete the clamping and fixing.
[0060] See appendix Figure 6 -Appendix Figure 9 The clamping arc plate 221 is provided with a clamping slider 222, and the outer wall of the second linkage wheel 212 is provided with a clamping groove 216 corresponding to the multiple clamping sliders 222; the clamping slider 222 is slidably disposed in the clamping groove 216 in the corresponding clamping slider 222 and clamping groove 216; the inner wall of the clamping arc plate 221 is provided with a second wedge 223 corresponding to the first wedge 219, and the outer wall of the second wedge 223 facing the first wedge 219 is provided with a wedge groove 224, and the first wedge 219 is slidably disposed in the wedge groove 224.
[0061] In this embodiment, the clamping assembly relies on the coordinated action of cylinder drive, wedge engagement, and slider guidance to convert axial power into radial clamping force, achieving precise and stable clamping of the winding drum. The cavity 220 of the fixed pile 214 provides an axial sliding trajectory for the moving pile 218. The first cylinder 217 serves as a power source, driving the moving pile 218 to perform axial extension and retraction within the cavity 220. Multiple first wedges 219 on the outer wall of the moving pile 218 move synchronously with it, and the first wedges 219 slide along the slot 215 of the fixed pile 214. The slot 215 guides and prevents rotation of the first wedges 219, ensuring the accuracy of their movement direction.
[0062] The clamping arc plate 221 forms a sliding engagement with the clamping groove 216 on the outer wall of the second linkage wheel 212 through the clamping slider 222 at the bottom. The clamping groove 216 limits the trajectory of the clamping arc plate 221 to only slide radially along the second linkage wheel 212, so as to avoid the clamping arc plate 221 from deviating or getting stuck during the movement, and to ensure the synchronicity of the movement of multiple clamping arc plates 221.
[0063] In this embodiment: a second wedge 223 is provided on the side of the clamping arc plate 221 facing the first wedge 219, and its wedge groove 224 is adapted to the first wedge 219. The first wedge 219 slides and fits in the wedge groove 224 to form a wedge-shaped transmission engagement.
[0064] When the take-up drum needs to be clamped, the first cylinder 217 pushes the moving pile 218 to extend axially along the cavity 220, causing the first wedge block 219 to slide outward along the slot 215. The wedge-shaped surface of the first wedge block 219 and the wedge-shaped surface of the wedge groove 224 fit and squeeze each other, converting the axial thrust into a force that drives the second wedge block 223 to move radially. This, in turn, pushes the clamping arc plate 221 to slide synchronously along the clamping groove 216 towards the axis of the second linkage wheel 212. Multiple clamping arc plates 221 together enclose and tightly fit the outer wall of the inner cylinder of the take-up drum, achieving a firm clamping of the take-up drum and ensuring the coaxiality of the take-up drum and the second linkage wheel 212.
[0065] See appendix Figure 10 -Appendix Figure 11 The second correction mechanism 3 includes a guide shaft 301 for moving the material to be wound, and adjustment components 302 disposed at both ends of the guide shaft 301. The second correction mechanism 3 adjusts the position of the guide shaft 301 through the adjustment components 302. The adjustment components 302 include a drive frame 303 and multiple slide rods 304. Slide seats 305 are slidably disposed between the multiple slide rods 304. Linkage seats 307 are disposed at both ends of the guide shaft 301. The linkage seats 307 are rotatably disposed on the slide seats 305.
[0066] In this embodiment: the second correction mechanism 3 uses the guide shaft 301 as the actuating component. The spatial position of the guide shaft 301 is adjusted by the adjustment component 302. By means of the contact between the guide shaft 301 and the material to be wound, the material is driven to move laterally to correct the deviation and realize the path correction of the material to be wound.
[0067] Adjustment components 302 are located at both ends of the guide shaft 301. Each adjustment component 302 consists of a drive frame 303 and multiple slide rods 304. The slide rods 304 are arranged in parallel and fixedly connected to the drive frame 303 to form a stable sliding guide base. The slide block 305 slides between the multiple slide rods 304. The slide rods 304 provide precise lateral sliding guidance for the slide block 305, ensuring the straightness of the slide block 305 during movement and avoiding deviations that could affect the correction accuracy.
[0068] In this embodiment, the linkage seats 307 at both ends of the guide shaft 301 are rotatably connected to the corresponding slide 305, so that the guide shaft 301 can rotate freely relative to the slide 305. This does not affect the normal conveying of the material to be wound along the guide shaft 301, and allows the guide shaft 301 to adjust its position synchronously with the movement of the slide 305.
[0069] When the detection component 102 detects a lateral offset in the material to be wound, the adjustment component 302 drives the slide block 305 to slide laterally along the slide bar 304 in the corresponding direction and amplitude. The slide block 305 drives the guide shaft 301 to move laterally in sync through the linkage seat 307. During the movement, the guide shaft 301 is in close contact with the lower or upper side of the material to be wound. The friction between the two drives the material to be wound to move laterally in the same direction, directly correcting the material's feeding path and returning the material to the reference conveying position, thus completing the offset correction at the material end.
[0070] In this embodiment, the adjustment components 302 at both ends can operate synchronously to ensure that the guide shaft 301 always remains horizontal, avoiding new material offset caused by the tilt of the guide shaft 301. Together with the first correction mechanism 2, the position of the take-up drum is corrected, realizing synchronous linkage correction between the take-up drum and the material to be taken up, improving the overall correction accuracy, and effectively avoiding the problem of secondary material offset.
[0071] See appendix Figure 10 -Appendix Figure 11 Appendix Figure 2 The adjustment component 302 includes a second cylinder 306, the output end of which is connected to the slide 305; the control panel 1 is provided with a control panel 101; the detection component 102 includes a receiving part 103 and a sensor 104; the receiving part 103 is used for the material to be wound to pass through, and the sensor 104 is used to detect the offset range of the material to be wound.
[0072] In this embodiment: the control panel 101 on the operator console 1 is the control core of the entire correction device, which can realize the detection, the issuance of drive commands and the adjustment of parameters.
[0073] The receiving part 103 of the detection component 102 provides a passage for the material to be wound, allowing the material to pass through the detection area along a preset path. The sensor 104 is arranged corresponding to the receiving part 103 and can detect the lateral offset direction and offset range of the material to be wound through in real time, and transmit the detected signal to the control panel 101 in real time.
[0074] In this embodiment: the adjustment component 302 uses the second cylinder 306 as the power source. The second cylinder 306 is electrically connected to the control panel 101, and its output end is fixedly connected to the slide 305. When the control panel 101 receives the offset signal from the sensor 104, it will send a corresponding drive command to the second cylinder 306 according to the offset data. After receiving the command, the second cylinder 306 starts and drives the slide 305 to slide precisely laterally along multiple parallel slide rods 304 through the extension and retraction of the output end. The slide rods 304 provide stable linear guidance for the slide 305, avoiding deviation or jamming during the sliding process of the slide 305.
[0075] In this embodiment: the linkage seats 307 at both ends of the guide shaft 301 are rotatably connected to the slide 305, so that the guide shaft 301 can adjust its position synchronously with the lateral sliding of the slide 305. At the same time, the guide shaft 301 can rotate freely relative to the slide 305 without affecting the normal conveying of the material to be wound along the guide shaft 301. When the guide shaft 301 moves with the slide 305, it drives the material to be wound to move laterally in the opposite direction of the offset through the frictional force of the contact with the material surface, accurately correcting the material's path and returning the material to the reference conveying position.
[0076] The adjustment components 302 at both ends are synchronously controlled by the control panel 101 to ensure that the sliding distance and direction of the sliding blocks 305 on both sides are consistent, so that the guide shaft 301 always remains horizontal and avoids new material deviation caused by the tilt of the guide shaft 301. Throughout the process, the detection component 102 detects in real time, the control panel 101 performs precise calculations, and the second cylinder 306 drives quickly to realize the automated and precise correction of the deviation of the material to be wound. In conjunction with the position correction of the winding drum of the first correction mechanism 2, the synchronous linkage correction of the winding drum and the material to be wound is completed.
