Description

Technical Field

[0001] This invention relates to the field of winding equipment technology, specifically a roller-pressed rewinding switching assembly and method. Background Technology

[0002] In the production or processing of sheet materials (such as films), the produced or processed sheets are generally wound up by a winding device. Traditional winding devices typically have only one winding shaft. When the diameter of the sheet material wound on the winding shaft reaches the set value and a change of roll is required, the machine must be stopped, and a worker must manually remove the finished roll and install a new winding shaft to allow winding to continue. When switching to a new winding roller, the winding paper needs to be cut, and then the ends of the roll are glued together with adhesive. Only after the connection is completed can the winding process continue. This operation is time-consuming and does not help to improve the speed of roll changeover.

[0003] Based on this, a roll-pressed rewinding switching assembly and method are provided to eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-13As shown, a roll-pressed, docking-type take-up switching assembly includes two mounting plates 100. A lower pressure roller 101 and a support roller 102 are rotatably disposed between the two mounting plates 100. A transmission gap is provided between the lower pressure roller 101 and the support roller 102 to facilitate fabric transmission. A cutting component 200 for cutting the fabric is provided on each mounting plate 100. A roller switching component 400 for fixing a take-up roller 103 is provided on one side of the cutting component 200. The take-up roller 103 is fixed and driven by the roller switching component 400, thereby completing the take-up of the fabric. Below the roller switching component 400... A roller transfer component 500 is provided for transferring the take-up roller 103, so that the taken-up roller 103 after being wound can be transferred away, or the take-up roller 103 about to be wound can be transferred to the docking position, reducing labor intensity; the mounting frame plate 100 is also provided with an auxiliary docking component 300 for pressing the cut fabric tightly onto the take-up roller 103 to complete the quick docking. The auxiliary docking component 300 presses the end of the fabric tightly against the take-up roller 103, so that the take-up roller 103 can wind up the fabric. After the end of the fabric is wound up, the pressing action of the auxiliary docking component 300 can be canceled. In one embodiment, such as Figures 10-12 As shown, the auxiliary docking component 300 includes a docking base 301. Both ends of the docking base 301 are fixedly connected to the inner side of the mounting plate 100. Two docking telescopic rods 306 are provided at the lower end of the docking base 301. The telescopic rods 306 are connected to a fine-tuning component for adjusting the distance between them. The fine-tuning component allows adjustment of the distance between the two telescopic rods 306 to accommodate winding rollers 103 of different lengths. A telescopic arm 307 is provided at the output end of each telescopic rod 306. A buffer groove 322 is provided on the side of the telescopic arm 307. A sliding rod 309 slides within the buffer groove 322. A limiting protrusion 308 is provided at the upper end of the sliding rod 309. The protrusion 308 matches the groove at the top of the buffer slide 322. The end of the sliding rod 309 is connected to the tail plate 315 on the inner wall of the buffer slide 322 by a buffer spring 321. A pressure roller is rotatably provided between the two sliding rods 309. The pressure roller includes a first pressure tube 310 and a first pressure tube sleeve 314. The first pressure tube sleeve 314 is slidably sleeved on the outside of the first pressure tube 310, so that it can be automatically adjusted as the distance between the connecting telescopic rods 306 changes. The end of the sliding rod 309 where the pressure roller is located is also provided with a winding and pressing component for assisting the fabric to be bonded and wound. The winding and pressing component makes the fabric better bonded to the surface of the take-up roller 103 so as to wind the fabric. The winding and pressing component includes a suspension rod fixed to the end of the sliding slide rod 309. Multiple rotating plates 316 are provided at the lower end of the suspension rod. Adjacent rotating plates 316 are connected by connecting pieces 317, and the connecting pieces 317 and the rotating plates 316 are rotatably connected by pins. A rope groove 323 is provided on the side of the suspension rod and the rotating plates 316 facing the take-up roller 103. A limiting rod to prevent detachment is provided at the end of the rope groove 323. A guide tube assembly is rotatably provided between two symmetrically arranged rotating plates 316. The guide tube assembly includes a guide tube sleeve 311 and a guide tube body 312 rotatably connected to the rotating plates 316. The guide tube body 312 is slidably sleeved on the outside of the guide tube sleeve 311. A limiting side stop 313 is provided on the other side of the rotating plate 316 opposite to the rope groove 323 to restrict its rotation to that side. A take-up roller 319 is rotatably provided on the outside of the sliding slide rod 309. A traction rope 318 is wound around 319. The other end of the traction rope 318 passes through the rope groove 323 and is connected and fixed to the bottom of the lowest rotating strip 316. The take-up wheel 319 is connected to a traction drive unit for driving its rotation to achieve the take-up of the traction rope 318. The outer side of the take-up wheel 319 is provided with a storage groove that matches the traction rope 318. When the first pressing sleeve 314 and the first pressing tube 310 are driven by the docking telescopic rod 306, they will press the lower end of the fabric tightly against the surface of the take-up roller 103. As the docking telescopic rod 306 pushes further, under the action of the traction drive unit, the take-up wheel 319 will achieve the take-up of the traction rope 318. When taking up, due to the obstruction of the limiting side block 313, the long strip structure formed by the rotating strip 316 will curl toward the take-up roller 103, thereby adhering the fabric to the surface of the take-up roller 103, thereby assisting in the take-up of the end of the fabric. The traction drive unit includes a toothed ring disposed on the outside of the take-up reel 319. The upper end of the telescopic arm 307 is provided with a rack 320 that matches the toothed ring. When the connecting telescopic rod 306 drives the first pressing sleeve 314 and the first pressing tube 310 to move to the right and press against the surface of the take-up roller 103, the fabric is initially pressed tightly against the surface of the take-up roller 103. As the connecting telescopic rod 306 continues to push, the telescopic arm 307 continues to move, and slides in the buffer groove 322. Therefore, the rack 320 on the telescopic arm 307 will engage with the toothed ring, thereby driving the take-up reel 319 to rotate, thus winding up the traction rope 318. After collection, the long strip structure formed by multiple rotating plates 316 will curl upwards, causing the guide tube assembly to press the fabric against the surface of the take-up roller 103. Figure 11 As shown, this allows the ends of the fabric to be wrapped smoothly; The fine-tuning component includes a fine-tuning groove 305 disposed on the upper end of the docking base 301. Two fine-tuning sliders 303 are slidably disposed in the fine-tuning groove 305. The lower end of each fine-tuning slider 303 is connected to the docking telescopic rod 306. The fine-tuning sliders 303 are threaded on the fine-tuning screw 304. One end of the fine-tuning screw 304 is rotatably connected to the fixed block at the upper end of the docking base 301. The other end of the fine-tuning screw 304 is connected to a fine-tuning motor 302 for driving its rotation. The fine-tuning screw 304 is provided with threaded areas corresponding to the two fine-tuning sliders 303. The two threaded areas rotate in opposite directions. The fine-tuning motor 302 drives the fine-tuning screw 304 and the fine-tuning sliders 303 to rotate relative to each other. Under the action of the threads, the two fine-tuning sliders 303 slide along the upper end of the docking base 301 to adjust the distance between them. In one embodiment, such as Figure 8 As shown, the roller transfer component 500 includes a transfer base 501. A transfer slider 502 is slidably mounted on the upper end of the transfer base 501. The transfer slider 502 is threaded onto a transfer screw 503. One end of the transfer screw 503 is rotatably connected to a fixed block on the transfer base 501, and the other end is fixedly connected to the output end of a transfer motor 504 on the transfer base 501. A height adjustment telescopic rod 505 is mounted on the upper end of the transfer slider 502. A support base plate 508 is mounted on the output end of the height adjustment telescopic rod 505. Two rows of support rollers 506 are mounted on the upper end of the support base plate 508. The two rows of support rollers 506 are connected to the support base plate 508. The fixed side plate 507 at the upper end of the substrate 508 is rotatably connected, and the two rows of support rollers 506 are in a V-shape to support the take-up roller 103. Then, the roller can be rolled to one side to complete the transfer. The operation is convenient. The transfer motor 504 drives the transfer screw 503 and the transfer slider 502 to rotate relative to each other. Under the action of the screw, the transfer slider 502 can slide along the upper surface of the transfer base 501, thereby performing the initial transfer of the take-up roller 103 on the support substrate 508. By adjusting the height of the support substrate 508 through the height adjustment telescopic rod 505, the support rollers 506 can be raised to the bottom of the take-up roller 103 to complete the receiving or feeding. In one embodiment, such as Figures 4-6As shown, the roller switching component 400 includes a switching base 401. A set of switching vertical plates 403 are symmetrically arranged on both sides of the upper end of the switching base 401. A connecting shaft 412 is rotatably connected between the two switching vertical plates 403. Two flipping arms 406 are symmetrically arranged on the two connecting shafts 412. The connecting shafts 412 are connected to a switching drive component for rotating the arms. Each flipping arm 406 has a conical pressing block 413 at both ends for engaging with the end of the winding roller 103. A rotating disk 408 is fixed to the outer end of the conical pressing block 413. An adjusting slide 416 is located at the center of the end of the rotating disk 408. The adjusting slide 416 is slidably disposed with a rectangular hole at the end of the rotating column 414. A compression spring 415 for connecting the adjusting slide 416 is located in the rectangular hole at the end of the rotating column 414. The rotating column 414 is rotatably mounted on the tilting arm 406. A driven wheel 407 is provided at the outer end of the rotating column 414. The rotating disk 408 is connected to a traction member for driving it away from the driven wheel 407. The distance between the two opposing conical pressing blocks 413 can be adjusted by the traction member to dock and position take-up rollers 103 of different lengths. It also facilitates unloading the take-up rollers 103 between the two conical pressing blocks 413. Then, the connecting shaft 412 is rotated by the switching drive member to switch the position between the two take-up rollers 103 and transfer the replaced take-up rollers 103 to the take-up position. The driven wheel 407 is connected to a winding drive component 600 for driving its rotation. The winding drive component 600 contacts the driven wheel 407 to drive the take-up rollers 103 to rotate, providing power for winding. In one embodiment, such as Figure 13 As shown, the winding drive component 600 includes an auxiliary slider 601 fixedly connected to the outside of the mounting plate 100. A pressing slide 604 slides horizontally on the auxiliary slider 601. A fixing block 602 at the outer end of the pressing slide 604 is connected to the auxiliary slider 601 by a pressing spring 603. A winding motor 605 is provided at the end of the pressing slide 604 away from the fixing block 602. A driving wheel 606 is provided at the output end of the winding motor 605, which is in frictional contact with the outside of the driven wheel 407. The driven wheel 407 and the driving wheel... The outer surface of 606 is provided with an anti-slip layer. When the driven wheel 407 is switched to the position of the winding drive component 600, the driven wheel 407 and the driving wheel 606 are in abutting contact. The pressing spring 603 here provides a clamping force to maintain the transmission of power. The winding motor 605 drives the driving wheel 606 to rotate. The driving wheel 606 and the driven wheel 407 match to drive the conical pressing block 413 to rotate, thereby providing power for winding. The power transmission here is a soft connection. As the winding roller 103 is switched, the power is disconnected, so that the two winding positions share a power source. The traction component includes a traction ring rotatably disposed on the outside of the rotating disk 408. The outer end of the traction ring is connected to the output end of the double-headed telescopic rod 410 via a connecting rod 409. The double-headed telescopic rod 410 is connected and fixed to the connecting shaft 412 via a connecting frame 411. Under the traction of the double-headed telescopic rod 410, the position between the two conical pressing blocks 413 will change in order to adapt to winding rollers 103 of different lengths, as well as unloading and docking. The switching drive includes a worm gear 405 disposed at the end of the connecting shaft 412. The lower side of the worm gear 405 meshes with the worm 404. The worm 404 is connected to a flip motor 402 for driving its rotation. The flip motor 402 drives the worm 404 to rotate, and the worm 404 and the worm gear 405 cooperate to drive the connecting shaft 412 to rotate. In this way, switching power can be provided for the switching of the take-up roller 103. The cutting component 200 includes a cutting base 205 mounted between two mounting plates 100. A cutting slider 202 is slidably mounted on the two cutting bases 205. The cutting slider 202 is threaded onto a cutting screw 201. One end of the cutting screw 201 is rotatably connected to a bearing block at the upper end of the cutting base 205, and the other end of the cutting screw 201 is connected to a cutting motor 203 for driving its rotation. A steering motor is provided on the outside of the cutting slider 202. A cutting blade assembly 204 is provided at the output end of the steering motor. When the fabric needs to be cut, the steering motor first drives the cutting blade assembly 204 to rotate downward. Then, the cutting motor 203 drives the cutting screw 201 and the cutting slider 202 to rotate relative to each other. Under the action of the thread, the cutting slider 202 slides along the surface of the cutting base 205, thereby allowing the cutting slider 202 to slide along the cutting base 205. The cutting blade assembly 204 on the outside of the cutting slider 202 will cut the fabric so that a new take-up roller 103 can be replaced.

[0033] The above embodiment discloses a roller-pressed docking type take-up switching assembly. In actual use, the fabric is wrapped around the gap between the lower pressure roller 101 and the support roller 102, and the fabric is taken up by the take-up roller 103. When the surface of the take-up roller 103 is fully wrapped with fabric, the end of the fabric is cut off by the cutting component 200. The fully loaded fabric is taken away by the roller transfer component 500 at the winding position and transferred. During the receiving, the distance between the two opposing conical pressing blocks 413 is adjusted by the traction component so as to cancel the positioning of the take-up roller 103. Then, the unloaded take-up roller 103 is switched to the winding area by the roller switching component 400. Then, the first pressing sleeve 314 and the first pressing tube 310 are driven by the docking telescopic rod 306 to press the lower end of the fabric tightly against the surface of the take-up roller 103. As the docking telescopic rod 306 is pushed further, the take-up wheel 319 will take up the traction rope 318 under the action of the traction drive unit. When taking up, due to the obstruction of the limit side block 313, the long strip structure formed by the rotating strip 316 will curl towards the take-up roller 103, thereby adhering the fabric to the surface of the take-up roller 103, thus assisting in the take-up of the end of the fabric. In actual operation, the distance between the two opposing conical pressing blocks 413 can be adjusted by the traction component to position the winding rollers 103 of different lengths. In addition, the fine-tuning motor 302 can drive the fine-tuning screw 304 and the fine-tuning slider 303 to rotate relative to each other. Under the action of the thread, the two fine-tuning sliders 303 slide along the upper end of the docking base 301 to adjust the distance between them. In this way, the first pressing sleeve 314 and the first pressing tube 310 at the end of the telescopic arm 307 will also slide relative to each other, thereby pressing the fabric of different lengths and further improving the product's adaptability.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
