Description

Technical Field

[0001] This invention relates to the field of laminating machine technology, and specifically to a laminating machine for waterproof clothing fabrics. Background Technology

[0002] Waterproof clothing fabrics are the core base material for outdoor clothing, sportswear, and protective workwear. Their production process requires high-precision bonding of textile fabrics with waterproof films such as TPU and PU using a laminating machine. The winding device, as a critical end component of the laminating machine, directly affects the production continuity and finished product quality of waterproof clothing fabrics due to its high requirements for winding flatness and tension uniformity, and the frequent winding changes during production. Traditional winding devices are no longer sufficient to meet the demands of modern production.

[0003] Currently, the closest existing technology is the Chinese utility model patent with authorization announcement number CN206633553U and titled "Waterproof Clothing Fabric Laminating Machine". This patent discloses a structure for a waterproof clothing fabric laminating machine, including a frame, a distribution device, a front pneumatic edge-aligning device, a front conveyor belt device, a rear conveyor belt device, a heat-conducting oil-supported preheating wheel, a heated large roller laminating device, and a winding device. It can realize continuous lamination of fabric and TPU film. By preheating the fabric with the heat-conducting oil-supported preheating wheel, the lamination strength of the fabric is effectively improved, solving the problems of poor lamination effect and easy delamination of waterproof fabrics in traditional laminating machines.

[0004] However, the existing winding device still has the following significant drawbacks: Low degree of automation in roll changing: The winding device is only a basic roller support structure. After winding, the fabric needs to be cut manually, the full roll winding roller needs to be disassembled and the empty roller needs to be replaced. The roll changing process is time-consuming, which seriously affects the continuity of production. In addition, manual operation can easily cause fabric wrinkles and stretching deformation, reducing the finished product qualification rate. Without mechanical timing interlock protection: The power cut-off, limit release and lifting actions of the take-up roller have no mandatory sequence, which can easily lead to mechanical interference due to operational errors. This can not only damage the equipment, but also cause large-scale fabric scrap. Insufficient reliability of the power clutch: The lack of an automatic alignment and engagement structure and an initial locking function makes it easy for the teeth to get stuck during the clutch operation. In addition, the power transmission path is prone to unexpected interruption during the winding operation, which can lead to sudden changes in fabric tension and quality problems such as wrinkles and belt breakage. Poor stability of the take-up roller lifting: The take-up roller is not designed with a special lifting structure for the high precision requirements of waterproof clothing fabrics. It is easy for the take-up roller to tilt during the lifting process, resulting in uneven end face and uneven roll diameter, which affects the subsequent cutting and sewing processes. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art.

[0006] This application provides a waterproof garment fabric laminating machine, including a frame, a heating roller, an adhesive tank, a winding device, a pair of feeding rollers, and several guide rollers. The winding device includes a winding roller, a winding frame, a lifting mechanism, an opening and closing mechanism, a power transmission mechanism, a winding drive mechanism, and a combined drive mechanism. The lifting mechanism and the opening and closing mechanism are respectively located at both ends of the winding frame. The combined drive mechanism is used to control the sequential action of the power transmission mechanism and the lifting mechanism. The power transmission mechanism is used to drive the opening and closing mechanism to simultaneously cut off or continue the power transmission path between the winding drive mechanism and the winding roller. One end of the winding roller is hinged to the lifting mechanism, and the other end is movably and detachably connected to the opening and closing mechanism. The opening and closing mechanism is used to fix the non-hinged end of the winding roller, and the lifting mechanism is used to drive the hinged end of the winding roller to rise and fall.

[0007] Furthermore, the lifting mechanism includes a lifting control slide plate, a connecting arm, a tilting unit, a pressing rod, and a pair of upright plates. The lifting control slide plate is slidably installed at the bottom of the winding frame. The pair of upright plates are symmetrically fixed at the top of one end of the winding frame. The tilting unit is hinged in the middle between the pair of upright plates. The pressing rod is movably installed at the top of the tilting unit for contacting the hinged end of the winding roller. The two ends of the connecting arm are respectively hinged to one end of the lifting control slide plate away from the winding mechanism and the lower end of the tilting unit.

[0008] Furthermore, the flipping unit includes a pair of receiving slots, a pair of flipping arms, and several arc grooves. The pair of receiving slots are respectively opened on the outer side wall of each upright plate. The several arc grooves are respectively set at the top and bottom of each upright plate and communicate with the receiving slots. The middle part of the pair of flipping arms is respectively hinged to the middle part of each receiving slot through a rotating shaft. The upper and lower ends of the pair of flipping arms are provided with sliding columns. Each sliding column is slidably engaged with the corresponding arc groove. The two ends of the pressing rod are hinged to the adjacent end faces of the upper pair of sliding columns, and the upper end of the connecting arm is hinged to the adjacent end faces of the lower pair of sliding columns.

[0009] Furthermore, the pressing rod is provided with a conformal groove that corresponds to the shape of the outer wall of the take-up roller.

[0010] Furthermore, the power transmission mechanism includes a rotating shaft, a turntable, a transmission rod, a transmission block, a power connection slide plate, an extension plate, and an extension slot. The rotating shaft is rotatably mounted on the end of the winding frame away from the lifting mechanism. The turntable is fixed on the top of the rotating shaft and is connected to the opening and closing mechanism and the winding drive mechanism. The transmission rod is fixed on the lower end of the rotating shaft and extends outward. The transmission block is fixed on the bottom of the outer end of the transmission rod. The power connection slide plate is slidably mounted on the bottom of the winding frame. The extension slot is opened on one side of the power connection slide plate to accommodate the transmission block. The extension plate is fixed on the power connection slide plate and adjacent to the extension slot.

[0011] Furthermore, the combined drive mechanism includes a disc, a rotary driver, a pair of push-pull sliders, and a pair of push-pull slots. The pair of push-pull sliders are respectively fixed on the lifting control slide plate and the power connection slide plate. The disc is rotatably mounted on the winding frame. The rotary driver is used to drive the disc to rotate in both directions. The pair of push-pull slots are opened on the disc and are respectively connected to each push-pull slider in a transmission manner. The push-pull slots include a holding section and a driving section that are interconnected. The holding section extends circumferentially along the disc, and the driving section extends radially along the disc. When one push-pull slider is located in the holding section of the corresponding push-pull slot, the other push-pull slider is located in the driving section of the other push-pull slot.

[0012] Furthermore, the rotary drive includes a first motor, a worm gear, and a worm. The worm gear is fixed on the outer ring of the disk, and the worm is rotatably mounted on the output shaft of the first motor and meshes with the worm gear for transmission.

[0013] Furthermore, the opening and closing mechanism includes a support frame, a top slide groove, a support block, a gear ring, a pair of opening and closing sliders, and a pair of racks. The support frame is fixed at the end of the take-up frame away from the lifting mechanism. The top slide groove is opened on the top surface of the support frame. The support block is fixed on the top surface of the support frame. The pair of opening and closing sliders are slidably installed on the top surface of the support frame and are located on both sides of the support block. The top of the rotating shaft passes through the top slide groove. The gear ring is located in the top slide groove and is fixedly connected to the turntable. The pair of racks are slidably installed in the top slide groove, fixedly connected to the lower end of each opening and closing slider, and mesh with the gear ring for transmission. Grooves are provided on the top surface of the support block and the adjacent side walls of the pair of opening and closing sliders. When the pair of opening and closing sliders are closed and cooperate with the support block, several grooves form receiving holes for accommodating the non-hinged end of the take-up roller.

[0014] Furthermore, the winding drive mechanism includes a transmission groove, a transmission shaft, a transmission arm, a through groove, a sliding frame, a clutch connector, a fixed plate, a second motor, a spline groove, a spline shaft, and a belt drive pair. The transmission groove is located on one side of the center of the turntable, the transmission shaft is fixed at one end of the transmission groove, the through groove is located on the side of the support frame away from the lifting mechanism and in the middle of the rack on the same side, the fixed plate is fixed at the end of the winding frame away from the lifting mechanism, the sliding frame is movably installed between the fixed plate and the support frame, the transmission arm slides through the through groove and the transmission groove in the middle, and its two ends are hinged to the sliding frame and the transmission shaft, respectively. The clutch connector is divided into two meshable parts, one part of which is movably installed on the sliding frame and has a spline groove, and the other part is fixed at the end of the winding roller. The spline shaft is rotatably installed on the fixed plate and slides into the spline groove. The belt drive pair is used for the transmission between the second motor shaft and the spline shaft.

[0015] Furthermore, the clutch connector includes a floating cylinder, a pair of fixed rings, a spring, a clutch disc, and several meshing teeth. The floating cylinder is movably mounted on the sliding frame. The pair of fixed rings are respectively fixed at both ends of the outer wall of the floating cylinder. The spring is sleeved on the outer wall of the floating cylinder and located between the sliding frame and the take-up roller. The clutch disc is fixed at the end of the take-up roller. The several meshing teeth are divided into two groups and are respectively fixed on the adjacent end faces of the clutch disc and the floating cylinder. The several meshing teeth in each group are distributed circumferentially. The two groups of meshing teeth mesh with each other when the clutch disc and the floating cylinder are closed.

[0016] The beneficial effects of this invention are as follows: 1. By cooperating with the turntable of the combined drive mechanism and a pair of push-pull grooves respectively equipped with holding section and drive section, the power transmission mechanism and the lifting mechanism form a mechanical timing interlock, which forces the sequential action logic of "power cut-limit release-rewinding roller lifting" and "rewinding roller falling-limit closing-power continuation", completely avoiding mechanism interference and ensuring the safety and continuity of waterproof clothing fabric roll changing operation.

[0017] 2. By ensuring the initial tight contact between the transmission block of the power transmission mechanism and the side wall of the power connection slide plate, the transmission rod, shaft and turntable are mechanically locked, preventing the opening and closing mechanism from being accidentally opened or the power transmission path from being accidentally interrupted during the winding operation. This ensures the stability of the winding tension of the waterproof clothing fabric and avoids wrinkles and stretching deformation of the fabric.

[0018] 3. The lever-type flipping arm of the lifting mechanism works in conjunction with the pressing rod located above the hinge end of the take-up roller. Using the hinge end of the take-up roller as the fulcrum, the non-hinged end is smoothly lifted and lowered by pressing the hinge end. The action is precise and impact-free, effectively preventing the take-up roller from tilting and ensuring the neatness of the take-up end of the waterproof clothing fabric.

[0019] 4. The floating cylinder of the clutch connector cooperates with the spring sleeved on its outer wall. When the tooth tips of the two sets of meshing teeth are aligned, the spring continuously applies axial preload. When the floating cylinder rotates, it automatically completes the alignment and meshing. At the same time, the radial floating of the floating cylinder can compensate for the coaxiality error between the winding roller and the spline shaft, avoid clutch jamming, and ensure the smoothness of power transmission.

[0020] 5. By cooperating with the extension plate and extension groove of the power transmission mechanism, the smooth switching of power transmission is achieved, ensuring that the opening and closing action of the opening and closing mechanism is completely synchronized with the power switching action of the winding drive mechanism, and the action stroke is precise and controllable, ensuring that the winding roller can be locked quickly and the power is restored, thus shortening the downtime for changing rolls.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The waterproof garment fabric laminating machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Example 1: This application provides a waterproof garment fabric laminating machine, including a frame 1, a heating roller 2, an adhesive tank 3, a winding device 4, a pair of feeding rollers 5, and several guide rollers 6. The winding device 4 includes a winding roller 41, a winding frame 42, a lifting mechanism 7, an opening and closing mechanism 8, a power transmission mechanism 9, a winding drive mechanism 10, and a combined drive mechanism 11. The lifting mechanism 7 and the opening and closing mechanism 8 are respectively located at both ends of the winding frame 42. The combined drive mechanism 11 is used to control the sequential action of the power transmission mechanism 9 and the lifting mechanism 7. The power transmission mechanism 9 is used to drive the opening and closing mechanism 8 to simultaneously cut off or continue the power transmission path between the winding drive mechanism 10 and the winding roller 41. One end of the winding roller 41 is hinged to the lifting mechanism 7, and the other end is movably and detachably connected to the opening and closing mechanism 8. The opening and closing mechanism 8 is used to fix the non-hinged end of the winding roller 41, and the lifting mechanism 7 is used to drive the hinged end of the winding roller 41 to rise and fall.

[0027] like Figures 1 to 11As shown, due to the above structure, when the non-hinged end of the take-up roller 41 is lifted, the combined drive mechanism 11 first drives the power transmission mechanism 9 to operate. The power transmission mechanism 9 simultaneously completes two linked actions: first, it drives the opening and closing mechanism 8 to open, releasing the radial limit on the non-hinged end of the take-up roller 41; second, it cuts off the power transmission path between the take-up drive mechanism 10 and the take-up roller 41, so that the take-up roller 41 is completely free from the power input and circumferential constraint. After the opening and closing mechanism 8 and the take-up drive mechanism 10 have both completed their engagement with the non-hinged end of the take-up roller 41 and stopped all actions, the combined drive mechanism 11 then drives the lifting mechanism 7 to operate. The lifting mechanism 7 drives the hinged end of the take-up roller 41 to lift, thereby driving the non-hinged end of the take-up roller 41 to lift synchronously, completing the lifting operation before changing the roll.

[0028] When the non-hinged end of the take-up roller 41 is lowered, the combined drive mechanism 11 first drives the lifting mechanism 7 to run in the opposite direction, causing the hinged end of the take-up roller 41 to descend, so that the non-hinged end of the take-up roller 41 falls to the preset position. After the lifting mechanism 7 completes all the lowering actions of the take-up roller 41 and stops all actions, the combined drive mechanism 11 then drives the power transmission mechanism 9 to run in the opposite direction. The power transmission mechanism 9 simultaneously completes two linkage actions: first, it drives the opening and closing mechanism 8 to close, completing the radial limit fixation of the non-hinged end of the take-up roller 41; second, it continues the power transmission path between the take-up drive mechanism 10 and the take-up roller 41, restoring the power input of the take-up roller 41, and completing the lowering lock and power restoration operation of the take-up roller 41.

[0029] Example 2: In this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting mechanism 7 includes a lifting control slide plate 71, a connecting arm 72, a flipping unit 73, a pressing rod 74, and a pair of upright plates 75. The lifting control slide plate 71 is slidably mounted on the bottom of the winding frame 42. The pair of upright plates 75 are symmetrically fixed to the top of one end of the winding frame 42. The flipping unit 73 is hinged in the middle between the pair of upright plates 75. The pressing rod 74 is movably mounted on the hinged end of the flipping unit 73 for contacting the winding roller. The two ends of the connecting arm 72 are respectively hinged to one end of the lifting control slide plate 71 away from the coupling mechanism 8 and the lower end of the flipping unit 73.

[0030] In this embodiment of the application, the flipping unit 73 includes a pair of receiving grooves 731, a pair of flipping arms 732, and a plurality of arc grooves 733. The pair of receiving grooves 731 are respectively opened on the outer side wall of each upright plate 75. The plurality of arc grooves 733 are respectively arranged at the top and bottom of each upright plate 75 and communicate with the receiving grooves 731. The middle part of the pair of flipping arms 732 is respectively hinged to the middle part of each receiving groove 731 through a rotating shaft 91. The upper and lower ends of the pair of flipping arms 732 are provided with sliding posts 734. Each sliding post 734 is slidably engaged with the corresponding arc groove 733. The two ends of the pressing rod 74 are hinged to the adjacent end faces of the upper pair of sliding posts 734, and the upper end of the connecting arm 72 is hinged to the adjacent end faces of the lower pair of sliding posts 734.

[0031] Bearings are provided at both the hinge position and the position where the take-up roller 41 cooperates with the opening and closing mechanism 8. The hinge position also includes a bearing sleeve. The bearing at the hinge position of the take-up roller 41 is rotatably installed in the bearing sleeve. The two sides of the bearing sleeve are rotatably installed on a pair of vertical plates 75 through pins.

[0032] In this embodiment of the application, the pressing rod 74 is provided with a conformal groove 735 that corresponds to the shape of the outer wall of the take-up roller 41.

[0033] like Figures 3 to 8 As shown, due to the above structure, when lifting the non-hinged end of the take-up roller 41, the combined drive mechanism 11 drives the lifting control slide plate 71 to slide horizontally along the bottom of the take-up frame 42 towards the opening and closing mechanism 8. The connecting arm 72 pulls the lower end of the tilting arm 732, causing the tilting arm 732 to tilt downwards around the hinge point 91 with the vertical plate 75 at its center. During the tilting process, the sliding columns 734 at both ends of the tilting arm 732 slide directionally along the corresponding arc grooves 733. The lower sliding column... 734 swings upward with the lower end of the tilting arm 732, and the upper sliding column 734 swings downward with the upper end of the tilting arm 732, thereby driving the pressing rod 74 to move downward in an arc shape in sync. The conformal groove 735 on the pressing rod 74 fits tightly with the upper surface of the hinge end of the take-up roller 41, pressing down on the hinge end of the take-up roller 41. Since the take-up roller 41 is a rigid component, when its hinge end is pressed down, the non-hinged end will lift up synchronously with the hinge end as the fulcrum, completing the lifting operation of the non-hinged end of the take-up roller 41.

[0034] When the non-hinged end of the take-up roller 41 is lowered, the combined drive mechanism 11 drives the lifting control slide plate 71 to slide horizontally along the bottom of the take-up frame 42 away from the coupling mechanism 8. The connecting arm 72 pushes the lower end of the flipping arm 732, causing the flipping arm 732 to reverse. The upper sliding column 734 slides upward along the arc groove 733, driving the pressing rod 74 to move vertically upward in sync, releasing the downward pressure on the hinged end of the take-up roller 41 until it is separated from the take-up roller 41. The hinged end of the take-up roller 41 rises upward under the combined action of its own weight and the weight of the non-hinged end, while the non-hinged end falls downward in sync until the non-hinged end of the take-up roller 41 falls to the preset position, and the lifting control slide plate 71 stops sliding.

[0035] The conformal groove 735 on the pressing rod 74 is adapted to the shape of the outer wall of the take-up roller 41, and can maintain surface contact with the hinged end of the take-up roller 41 during the pressing process, so as to avoid stress concentration and damage to the surface of the take-up roller 41. The pressing rod 74 is hinged to the sliding column 734 at the upper end of the flipping arm 732, which can adapt to the angle change of the hinged end of the take-up roller 41 and ensure that a good fit is always maintained during the pressing process.

[0036] Example 3: In this embodiment, in addition to the structural features of the aforementioned embodiments, the power transmission mechanism 9 includes a rotating shaft 91, a turntable 92, a transmission rod 93, a transmission block 94, a power connection slide plate 95, an extension plate 96, and an extension groove 97. The rotating shaft 91 is rotatably mounted on the end of the winding frame 42 away from the lifting mechanism 7. The turntable 92 is fixed on the top of the rotating shaft 91 and is connected to the opening and closing mechanism 8 and the winding drive mechanism 10. The transmission rod 93 is fixed on the lower end of the rotating shaft 91 and extends outward. The transmission block 94 is fixed on the bottom of the outer end of the transmission rod 93. The power connection slide plate 95 is slidably mounted on the bottom of the winding frame 42. The extension groove 97 is opened on one side of the power connection slide plate 95 to accommodate the transmission block 94. The extension plate 96 is fixed on the power connection slide plate 95 and adjacent to the extension groove 97.

[0037] like Figures 3 to 8 As shown, due to the above structure, in the initial state, the outer wall of the transmission block 94 is in close contact with the side wall of the power connection slide plate 95 facing the lifting mechanism 7. At this time, the transmission rod 93 is completely limited and locked by the side wall of the power connection slide plate 95, and cannot rotate. Thus, the initial locking of the opening and closing mechanism 8 and the winding drive mechanism 10 is achieved through the rotating shaft 91 and the turntable 92, preventing them from being accidentally opened or interrupted during the winding operation.

[0038] When performing the pre-action before lifting the non-hinged end of the take-up roller 41, the power connection slide plate 95 slides horizontally along the bottom of the take-up frame 42 away from the lifting mechanism 7. During the sliding process, the extension plate 96 first contacts the side wall of the transmission block 94. As the power connection slide plate 95 continues to slide, the extension plate 96 gradually guides the transmission block 94 to the slot opening of the extension groove 97 until the transmission block 94 is fully engaged in the extension groove 97. At this point, the locking state of the transmission rod 93 is released. The power connection slide plate 95 continues to slide away from the lifting mechanism 7, driving the transmission block 94 through the groove wall of the extension groove 97. The synchronous movement causes the transmission rod 93 to rotate around the rotating shaft 91. The transmission rod 93 drives the rotating shaft 91 to rotate synchronously, and the rotating shaft 91 drives the top turntable 92 to rotate synchronously. The turntable 92 transmits the rotational power synchronously to the opening and closing mechanism 8 and the winding drive mechanism 10, synchronously driving the opening and closing mechanism 8 to open and the power transmission path between the winding drive mechanism 10 and the winding roller 41 to be cut off. When the transmission rod 93 rotates to the preset maximum angle, the power connection slide plate 95 stops sliding. The opening and closing mechanism 8 and the winding drive mechanism 10 complete all actions and remain stationary, providing the triggering conditions for the subsequent action of the lifting mechanism 7.

[0039] When the resetting action is performed after the non-hinged end of the take-up roller 41 is placed, this action is triggered only after the lifting mechanism 7 completes the lowering action of the take-up roller 41 and stops. The power connection slide plate 95 slides horizontally in the opposite direction along the bottom of the take-up frame 42 towards the lifting mechanism 7. In the initial stage, the transmission block 94 is engaged in the extension groove 97. The power connection slide plate 95 drives the transmission block 94 to move in the opposite direction through the groove wall of the extension groove 97, thereby driving the transmission rod 93, the rotating shaft 91 and the turntable 92 to rotate in the opposite direction. When the transmission rod 93 rotates in the opposite direction to the initial angle, the transmission block 94 just disengages from the extension groove 97 and re-engages tightly with the side wall of the power connection slide plate 95 facing the lifting mechanism 7, restoring the locking state of the transmission rod 93. At this time, the rotating shaft 91 and the turntable 92 are completely reset to the initial position. The turntable 92 synchronously drives the opening and closing mechanism 8 to close, and the power transmission path of the take-up drive mechanism 10 and the take-up roller 41 is connected and completed, realizing the locking and power restoration of the take-up roller 41.

[0040] Example 4: In this embodiment, in addition to the structural features of the aforementioned embodiments, the combined drive mechanism 11 includes a disc 111, a rotary driver 112, a pair of push-pull sliders 113, and a pair of push-pull grooves 114. The pair of push-pull sliders 113 are respectively fixed on the lifting control slide plate 71 and the power connection slide plate 95. The disc 111 is rotatably mounted on the winding frame 42. The rotary driver 112 is used to drive the disc 111 to rotate in both directions. The pair of push-pull grooves 114 are formed on the disc 111 and are respectively connected to each push-pull slider 113. The push-pull groove 114 includes a holding section 1141 and a driving section 1142 that are interconnected. The holding section 1141 extends circumferentially along the disc 111, and the driving section 1142 extends radially along the disc 111. When one push-pull slider 113 is located in the holding section 1141 of the corresponding push-pull groove 114, the other push-pull slider 113 is located in the driving section 1142 of the other push-pull groove 114.

[0041] In this embodiment of the application, the rotary driver 112 includes a first motor 1121, a worm gear 1122 and a worm 1123. The worm gear 1122 is fixed on the outer ring of the disk 111, and the worm 1123 is rotatably mounted on the output shaft of the first motor 1121 and meshes with the worm gear 1122 for transmission.

[0042] like Figures 3 to 8 As shown, due to the above structure, when the take-up roller 41 is lifted, the rotary driver 112 drives the disc 111 to rotate in the forward direction. In the initial stage, the push-pull slider 113 corresponding to the power connection slide plate 95 is in the driving section 1142 of the corresponding push-pull groove 114, and the push-pull slider 113 corresponding to the lifting control slide plate 71 is in the holding section 1141 of the corresponding push-pull groove 114. When the disc 111 rotates in the forward direction, the push-pull slider 113 on the power connection slide plate 95 is moved first through the driving section 1142, thereby driving the power transmission. Mechanism 9 completes the opening and closing mechanism 8 and the cutting off of the power transmission path. After the power transmission mechanism 9 completes its operation, the push-pull slider 113 corresponding to the power connection slide plate 95 enters the holding section 1141 of the corresponding push-pull groove 114. At the same time, the push-pull slider 113 corresponding to the lifting control slide plate 71 enters the driving section 1142 of the corresponding push-pull groove 114. The disc 111 continues to rotate in the forward direction, only driving the push-pull slider 113 on the lifting control slide plate 71 to move, thereby driving the lifting mechanism 7 to perform the lifting action of the take-up roller 41. There is no action interference throughout the process.

[0043] When the take-up roller 41 is lowered, the rotary driver 112 drives the disc 111 to rotate in the reverse direction. Initially, the push-pull slider 113 corresponding to the lifting control slide plate 71 is in the driving section 1142 of the corresponding push-pull groove 114, and the push-pull slider 113 corresponding to the power connection slide plate 95 is in the holding section 1141 of the corresponding push-pull groove 114. When the disc 111 rotates in the reverse direction, the drive section 1142 first drives the push-pull slider 113 on the lifting control slide plate 71 to move in the reverse direction, thereby driving the lifting mechanism 7 to execute the take-up roller 41. The descent action continues until the take-up roller 41 is positioned at the preset work station. After the lifting mechanism 7 completes its action, the push-pull slider 113 corresponding to the lifting control slide plate 71 enters the holding section 1141 of the corresponding push-pull groove 114. At the same time, the push-pull slider 113 corresponding to the power connection slide plate 95 enters the driving section 1142 of the corresponding push-pull groove 114. The disc 111 continues to rotate in the opposite direction, only driving the push-pull slider 113 on the power connection slide plate 95 to move in the opposite direction, thereby driving the power transmission mechanism 9 to complete the action of closing the opening and closing mechanism 8 and connecting the power transmission path.

[0044] The rotary driver 112 adopts a worm gear 1122 and worm 1123 transmission structure. The first motor 1121 drives the worm 1123 to rotate. Through the meshing of the worm 1123 and the worm gear 1122, the disc 111 is driven to rotate. The worm gear 1122 and worm 1123 transmission has a reverse self-locking characteristic, which can lock the disc 111 when it rotates to any position, avoid the disc 111 from rotating unexpectedly, ensure the stability of the action sequence and position of the two mechanisms, and effectively prevent action interference and position deviation.

[0045] Example 5: In this embodiment, in addition to the structural features of the aforementioned embodiments, the opening and closing mechanism 8 includes a support frame 81, a top sliding groove 82, a support block 83, a gear ring 84, a pair of opening and closing sliders 85, and a pair of racks 86. The support frame 81 is fixedly mounted on the end of the winding frame 42 away from the lifting mechanism 7. The top sliding groove 82 is formed on the top surface of the support frame 81. The support block 83 is fixedly mounted on the top surface of the support frame 81. The pair of opening and closing sliders 85 are slidably mounted on the top surface of the support frame 81 and are respectively located on both sides of the support block 83. The top end of the rotating shaft 91 passes through the top sliding groove 82. The gear ring 84 is located in the top sliding groove 82 and is fixedly connected to the turntable 92. A pair of racks 86 are slidably installed in the top sliding groove 82, respectively fixedly connected to the lower end of each opening and closing slider 85, and simultaneously meshing with the gear ring 84 for transmission. The top surface of the support block 83 and the adjacent side walls of the pair of opening and closing sliders 85 are provided with grooves. When the pair of opening and closing sliders 85 are closed and cooperate with the support block 83, several grooves form receiving holes 87 for accommodating the non-hinged end of the take-up roller 41.

[0046] like Figures 3 to 9As shown, due to the above structure, when the opening action before lifting the take-up roller 41 is performed, the turntable 92 drives the gear ring 84 to rotate on a fixed axis within the top slide groove 82 of the support frame 81. The gear ring 84 simultaneously meshes with the racks 86 on both sides, driving the two racks 86 to slide in opposite directions along the top slide groove 82. The two racks 86 respectively drive the corresponding opening and closing sliders 85 to slide synchronously along the top surface of the support frame 81 away from the support block 83, so that the groove between the opening and closing sliders 85 and the support block 83 is separated, releasing the radial limit on the non-hinged end of the take-up roller 41 and providing clearance space for the lifting of the take-up roller 41. After the opening and closing sliders 85 slide to the preset opening position, the turntable 92 stops rotating, and the opening and closing mechanism 8 remains in an open and stationary state. Only after the lifting mechanism 7 has completed all lifting and lowering actions will the reverse closing action be performed.

[0047] When the take-up roller 41 is lowered into position and the closing action is performed, this action is only triggered after the lifting mechanism 7 has lowered the take-up roller 41 to contact the groove on the top of the support block 83 and stopped. The turntable 92 drives the gear ring 84 to rotate in the opposite direction. Through the meshing transmission between the gear ring 84 and the rack 86, the two racks 86 are driven to slide in opposite directions along the top slide groove 82, which in turn drives the two opening and closing sliders 85 to slide synchronously along the top surface of the support frame 81 towards the support block 83 until the two opening and closing sliders 85 are fully engaged with the support block 83. At this time, the grooves on the top surface of the support block 83 and the adjacent side walls of the two opening and closing sliders 85 form a complete receiving hole 87. The non-hinged end of the take-up roller 41 is limited in the receiving hole 87, realizing the radial and axial precise limiting of the non-hinged end of the take-up roller 41, and avoiding the take-up roller 41 from moving or jumping during the winding operation.

[0048] Example 6: In this embodiment, in addition to the structural features of the aforementioned embodiments, the winding drive mechanism 10 includes a transmission groove 101, a transmission shaft 102, a transmission arm 103, a through groove 104, a sliding frame 105, a clutch connector 106, a fixing plate 107, a second motor 108, a spline groove, a spline shaft 109, and a belt drive pair 1010. The transmission groove 101 is located on one side of the middle of the turntable 92, the transmission shaft 102 is fixed to one end of the transmission groove 101, the through groove 104 is located on the side of the support frame 81 away from the lifting mechanism 7 and in the middle of the rack 86 on the same side, the fixing plate 107 is fixed to the end of the winding frame 42 away from the lifting mechanism 7, and the sliding frame 105... The movable mounting plate 107 is connected to the support frame 81 (the support frame 81 has slots on both sides for sliding engagement with the sides of the sliding frame 105). The transmission arm 103 slides through the through slot 104 and the transmission slot 101 in the middle, and its two ends are hinged to the sliding frame 105 and the transmission shaft 102 respectively. The clutch connector 106 is divided into two meshable parts, one part of which is movably mounted on the sliding frame and has a spline groove, and the other part is fixed to the end of the take-up roller 41. The spline shaft 109 is rotatably mounted on the mounting plate 107 and slides into the spline groove. The belt drive pair 1010 is used for the transmission between the shaft of the second motor 108 and the spline shaft 109.

[0049] like Figures 3 to 10 As shown, due to the above structure, when the power cutting action is performed before the take-up roller 41 is lifted, the turntable 92 rotates with the rotating shaft 91, and the transmission groove 101 on the turntable 92 rotates synchronously around the axis of the turntable 92. Through the transmission shaft 102 in the transmission groove 101, one end of the transmission arm 103 is driven to swing in a circle with the turntable 92. The middle part of the transmission arm 103 slides in the through groove 104, and the other end pulls the sliding frame 105 to move axially away from the take-up roller 41. The sliding frame 105 drives the movable part of the clutch connector 106 to move synchronously, so that the two parts of the clutch connector 106 separate from each other, completely cutting off the power transmission path between the take-up drive mechanism 10 and the take-up roller 41. This process is completed synchronously with the opening action of the opening and closing mechanism 8. After the clutch connector 106 is completely separated and the opening and closing mechanism 8 is fully opened, the turntable 92 stops rotating, and the take-up drive mechanism 10 remains stationary. Only after the lifting mechanism 7 has completed all lifting and lowering actions will the reverse power connection action be performed.

[0050] When the power relay action is performed after the take-up roller 41 is in place, this action is triggered only after the lifting mechanism 7 completes the lowering action of the take-up roller 41 and stops. The turntable 92 rotates in the opposite direction, and through the cooperation of the transmission groove 101, the transmission shaft 102 and the transmission arm 103, it pushes the sliding frame 105 to move axially towards the take-up roller 41, so that the movable part of the clutch connector 106 is fully engaged with the part fixed at the end of the take-up roller 41, and the power transmission path between the take-up drive mechanism 10 and the take-up roller 41 is restored. The second motor 108 drives the spline shaft 109 to rotate continuously through the belt drive pair 1010. The spline shaft 109 and the spline groove of the clutch connector 106 on the sliding frame 105 always maintain a sliding insertion engagement. No matter whether the sliding frame 105 is in the disengagement position or the engagement position, the spline shaft 109 can stably transmit the rotational power to the clutch connector 106.

[0051] Example 7: In this embodiment, in addition to the structural features of the aforementioned embodiments, the clutch connector 106 includes a floating cylinder 1061, a pair of fixed rings 1062, a spring 1063, a clutch disc 1064, and a plurality of meshing teeth 1065. The floating cylinder 1061 is movably mounted on the sliding frame 105. The pair of fixed rings 1062 are respectively fixed at both ends of the outer wall of the floating cylinder 1061. The spring 1063 is sleeved on the outer wall of the floating cylinder 1061 and located between the sliding frame 105 and the take-up roller 41. The clutch disc 1064 is fixed at the end of the take-up roller 41. The plurality of meshing teeth 1065 are divided into two groups and are respectively fixed on the adjacent end faces of the clutch disc 1064 and the floating cylinder 1061. The plurality of meshing teeth 1065 in each group are distributed circumferentially at intervals. The two groups of meshing teeth 1065 mesh with each other when the clutch disc 1064 and the floating cylinder 1061 are closed.

[0052] like Figures 3 to 11 As shown, due to the above structure, when the separation action is performed, the sliding frame 105 drives the floating cylinder 1061 to move axially away from the take-up roller 41, the spring 1063 extends, and the meshing teeth 1065 at the end of the floating cylinder 1061 completely disengage from the meshing teeth 1065 on the clutch disc 1064, completely cutting off the power transmission path. This action is smooth and impact-free throughout, avoiding damage to the meshing teeth 1065. After the two sets of meshing teeth 1065 are completely separated, the sliding frame 105 stops moving, and the clutch connector 106 remains in a separated and stationary state, providing a prerequisite for the subsequent action of the lifting mechanism 7.

[0053] When the meshing action is performed, this action is triggered only after the lifting mechanism 7 completes the lowering action of the take-up roller 41 and stops. The sliding frame 105 drives the floating cylinder 1061 to move axially towards the take-up roller 41 to the preset meshing position. If the two sets of meshing teeth 1065 happen to be aligned at this time, the elastic force of the spring 1063 will push the floating cylinder 1061 to press against the clutch disc 1064, so that the two sets of meshing teeth 1065 are directly and completely engaged. If the tooth tips of the two sets of meshing teeth 1065 are aligned at this time, the sliding frame 105 will still move to the preset position, the spring 1063 will be further compressed and continuously apply an axial preload force towards the clutch disc 1064 to the floating cylinder 1061. When the second motor 108 starts and drives the spline shaft 109 and the floating cylinder 1061 to rotate slowly, the tooth tips of the meshing teeth 1065 will slide into the adjacent tooth groove along the inclined surface, and automatically complete the precise alignment and meshing under the action of the preload force of the spring 1063.
