Description

Technical Field

[0001] This invention relates to the field of winding device technology, specifically to a winding device for producing conductive PU leather base fabric. Background Technology

[0002] Conductive PU leather is made by adding conductive materials to polyurethane. It possesses excellent conductivity, wear resistance, cold resistance, resistance to acids and alkalis, and oxidation resistance. Furthermore, conductive PU leather is soft, flexible, and resistant to both high and low temperatures. It is widely used in electronic devices, automotive interiors, and medical equipment—fields requiring conductivity. During the production of conductive PU leather, the base fabric needs to be rolled up to facilitate subsequent processing.

[0003] Most existing winding devices for conductive PU leather base fabric production use multiple rotating shafts to tightly wind the produced base fabric onto one of the shafts. Once the thickness or total length of the base fabric roll reaches the required level, the winding device is stopped, and then the guillotine is activated to cut the base fabric. The base fabric roll, which is usually quite heavy, is then unloaded. This unloading process often requires manual labor, where workers slide the base fabric roll off and carry it away from the winding device for transfer and storage. This is very laborious and troublesome, and there is a risk of foot injuries and damage to the base fabric. This process wastes a lot of time after the conductive PU leather base fabric is wound, reducing the winding efficiency after base fabric production. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a winding device for the production of conductive PU leather base fabric, which can automatically cut the base fabric after it is wound to a certain thickness, and unload and transfer the base fabric roll, so as to save manpower, simplify the operation process, and improve the winding efficiency of the base fabric.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A winding device for producing conductive PU leather base fabric includes a support frame and a winding module. The winding module includes a rotary drive module and a winding shaft. The rotary drive module includes a rotating disk rotatably mounted on the support frame, and the winding shaft is connected to the rotating disk. The device also includes: The pusher module includes a rotating ring sleeved on a rotating disk and a pusher plate slidably disposed on a take-up shaft. An extension module is provided between the pusher plate and the rotating ring. After the rotating ring and the rotating disk rotate relative to each other, the extension module pushes the pusher plate to slide on the take-up shaft. The thickness measuring module, locking module, and cutting module are respectively set on the bracket. After the thickness measuring module determines the thickness of the base fabric roll, the locking module controls the movement of the push plate, and the cutting module cuts the base fabric.

[0006] Furthermore, the locking module includes a clutch module, a response switching module, and a U-shaped rod. The response switching module includes a mounting box mounted on the bracket. The clutch module is located on the front side of the mounting box. The two ends of the U-shaped rod are slidably mounted inside the mounting box. The thickness measuring module is equipped with a thickness adjustment module. After the thickness adjustment module pushes the U-shaped rod, the clutch module controls the rotating ring to stop rotating.

[0007] Furthermore, a gear ring structure is provided on the inner side of the rotating ring. The clutch module includes a locking gear that meshes with the rotating ring and a rotating ratchet that is rotatably disposed in the mounting box. The locking gear and the rotating ratchet are connected to a rotating shaft. A sliding ratchet that meshes with the rotating ratchet is slidably disposed in the mounting box. A spring is provided between the sliding ratchet and the mounting box and is separated from the rotating ratchet. After the sliding ratchet meshes with the rotating ratchet, the locking gear and the rotating ring stop rotating.

[0008] Furthermore, a push plate is slidably arranged back and forth inside the mounting box, and a push rack is arranged along the rear side of the push plate. A telescopic tube is slidably arranged left and right inside the mounting box. The rear end of the telescopic tube abuts against the push plate, and the front end abuts against one end of the U-shaped rod. A tension spring is arranged between the telescopic tube and the U-shaped rod. A transmission rack is arranged on one side of the U-shaped rod. A steering gear is rotatably arranged inside the mounting box, which meshes with both the transmission rack and the push rack. A stop block is slidably arranged inside the telescopic tube. A spring is arranged between the stop block and the rear end of the telescopic tube. A through hole that matches the stop block is arranged on the front side wall of the mounting box at the position corresponding to the sliding ratchet.

[0009] Furthermore, the thickness measuring module includes a rotating rod and a thickness measuring rod rotatably mounted on the support. A torsion spring is provided between the rotating rod and the support, and a thickness adjustment module connected to a U-shaped rod is provided at the end. One end of the thickness measuring rod is rotatably mounted with a roller that abuts against the winding shaft, and the other end is slidably mounted on the rotating rod and is rotatably mounted with a connecting sleeve. The connecting sleeve is connected to a spacer ring movably mounted on the pusher plate.

[0010] Furthermore, the thickness adjustment module includes an adjustment disc mounted on a rotating rod, an adjustment groove arranged radially on the adjustment disc, a positioning bolt slidably mounted in the adjustment groove, a threaded sleeve threaded onto the positioning bolt, a push rod rotatably mounted on the threaded sleeve, and the other end of the push rod slidably mounted in a vertical sliding groove vertically mounted on a U-shaped rod.

[0011] Furthermore, the extension module includes parallel plates, multiple of which are provided between the pusher plate and the rotating ring. The parallel plates, pusher plate and rotating ring are respectively provided with grooves on their opposite surfaces. A hinge seat is rotatably provided in the groove. An extension rod is hinged between two corresponding hinge seats. The extension rod is adapted to the groove. A torsion spring is provided between the rotating ring and the rotating disk. After the rotating ring resumes rotation, it rotates through the torsion spring and the rotating disk.

[0012] The advantages of this invention compared to the prior art are: 1. The present invention is equipped with a pushing module, which can push the conductive PU leather base fabric roll from the side while the winding module continues to work, so that the base fabric roll leaves the winding module and is transferred to the transfer module on the other side. This allows for faster and more convenient unloading and transfer of the base fabric roll, improving the winding efficiency of the base fabric roll. 2. This invention is equipped with a thickness measuring module and a locking module, which can automatically unload the base fabric roll after the thickness of the conductive PU leather base fabric roll reaches the set value. No manual operation is required, and it does not rely on the electrical automatic control system, making production safer and more reliable, and operation simpler and more convenient. 3. The present invention is equipped with a cutting module, which can cut the base fabric before the pusher module pushes the base fabric roll, to prevent the base fabric from being stretched and deformed, making the operation simpler and more convenient, and the winding efficiency of the base fabric roll is higher. 4. This invention achieves process linkage through mechanical structure. It only requires setting the thickness of the base fabric roll through the thickness measuring module to automatically complete the entire process of base fabric winding, automatic cutting, and unloading. It is more convenient to use, simpler to operate, and has higher base fabric roll winding efficiency. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3As shown, a winding device for producing conductive PU leather base fabric includes a support 7 and a winding module 1. The winding module 1 includes a rotary drive module 12 and a winding shaft 11. The rotary drive module 12 includes a rotating disk 123 rotatably mounted on the support 7. The rotating shaft of the rotating disk 123 is connected to the output shaft of a gearbox 122 mounted on the support 7, and the input shaft of the gearbox 122 is connected to the drive shaft of a winding motor 121 mounted on the support 7. The winding shaft 11 is arranged laterally along the front and rear sides, and one end is mounted on the rotating disk 123. It has an adjustable width function to facilitate winding from the inside. The winding core is clamped from the side. The winding shaft 11 and its usage are existing technologies that are well known to the general public. A limit baffle 13 is provided on the winding shaft 11, and a certain distance is left between the limit baffle 13 and the rotating disk 123. A thickness measuring module 4 is provided on one side of the bracket 7, and a limit roller 71 is provided on the other side. A cutting module 5 is provided on the limit roller 71. A locking module 3 is provided on the top of the bracket 7, and the locking module 3 is connected to the thickness measuring module 4. A pushing module 2 is provided on the rotating disk 123 on one side of the winding shaft 11, and a transfer module 6 is provided on the other side.

[0027] In the above description, the rotating disk 123 is started, and the winding shaft 11 and the pushing module 2 rotate synchronously with the rotating disk 123. After the conductive PU leather base fabric is produced, it is positioned by the limiting roller 71, passes through the cutting module 5, and is wound onto the winding shaft 11. The thickness of the base fabric roll is measured and determined by the thickness measuring module 4. When the thickness of the base fabric roll reaches the set value, the thickness measuring module 4 automatically controls the locking module 3, so that part of the structure of the pushing module 2 is locked by the locking module 3, and the other part rotates synchronously with the rotating disk 123 and immediately unfolds, pushing the base fabric roll away from the winding shaft 11 and transferring it to the transfer module 6. It is worth noting that there is a certain distance between the limiting baffle 13 and the rotating disk 123, so that the transfer module 6 unfolds and controls the cutting module 5 to cut the base fabric in advance before pushing the base fabric roll, and then pushes the base fabric roll.

[0028] Combined with appendix Figure 3 Appendix Figure 4 Appendix Figure 5As shown, the pusher module 2 includes a rotating ring 21 sleeved on the rotating disk 123 and a pusher plate 22 slidably disposed on the take-up shaft 11. A torsion spring 24 is provided between the rotating ring 21 and the rotating disk 123. A gear ring structure is provided on the inner side of the rotating ring 21. The pusher plate 22 rotates with the take-up shaft 11, and a spacer ring 25 is movably sleeved on the outer side (the spacer ring 25 is rotatably disposed on the pusher plate 22 and moves with the pusher plate 22). An extension module 23 is provided between the pusher plate 22 and the rotating ring 21. The extension module 23 includes a parallel plate 231. Three hexagonal grooves 232 are provided between the parallel plate 231 and the rotating ring 21, and hexagonal grooves 232 are provided on the opposite surfaces of the parallel plate 231, the pusher plate 22 and the rotating ring 21. A hinge seat 233 is rotatably mounted within each groove 232, and three hinge seats 233 are evenly distributed circumferentially within each groove 232 (the hinge seats 233 are rotatably positioned at the corners of the groove 232). An extension rod 234 is hinged between two corresponding hinge seats 233, and the extension rod 234 is adapted to the groove 232. After folding, the extension rod 234 is arranged within the groove 232. The shape of the limiting baffle 13 is as shown in the attached figure. Figure 5 As shown, it is compatible with the pusher plate 22 and will not obstruct the moving pusher plate 22.

[0029] In the above description, after the rotating ring 21 stops rotating under the control of the locking module 3, the pusher plate 22 rotates with the take-up shaft 11, and the rotating ring 21 and the pusher plate 22 rotate, causing the extension rods 234 to fold and unfold, pushing the pusher plate 22, causing the pusher plate 22 to slide back and forth on the take-up shaft 11, and pushing the base fabric roll. At the same time, the rotating ring 21 and the rotating disk 123 rotate, causing the torsion spring 24 to rotate. After the rotating ring 21 resumes rotation, the torsion spring 24 rotates. The elastic potential energy stored in spring 24 is released, causing the rotating ring 21 to rotate between the torsion spring 24 and the rotating disk 123 (the rotation direction of the rotating ring 21 is the same as that of the rotating disk 123, and opposite to the relative rotation direction between the two after the rotation stops. Under the release of the energy stored in the torsion spring 24, the rotating ring 21 accelerates and catches up with the number of rotations that were missed during the rotation process), causing each extension rod 234 to fold and unfold in the opposite direction, and the position and state of the push plate 22 and the take-up shaft 11 are restored.

[0030] Combined with appendix Figure 2 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9As shown, the locking module 3 includes a clutch module 31, a response switching module 32, and a U-shaped rod 33. The response switching module 32 includes a mounting box 321 mounted on the bracket 7. A push plate 325 is slidably disposed in the mounting box 321. A push rack 327 is disposed along the rear side of the push plate 325. A telescopic tube 322 is slidably disposed on the front side. The other end of the telescopic tube 322 is slidably disposed in the mounting box 321. Both ends of the U-shaped rod 33 are slidably disposed in the mounting box 321. On one side of the rod... A transmission rack 331 is provided, and the other side rod abuts against the telescopic tube 322, with a tension spring 332 between it and the telescopic tube 322. A steering gear 326 is rotatably provided inside the mounting box 321, which meshes with both the transmission rack 331 and the propulsion rack 327. A stop block 323 is slidably provided inside the telescopic tube 322, and a spring is provided between the stop block 323 and the rear end of the telescopic tube 322. A through hole 324 that matches the stop block 323 is provided on the front side wall of the mounting box 321 corresponding to the clutch module 31.

[0031] Combined with appendix Figure 2 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 As shown, the clutch module 31 has a locking gear 311 that meshes with the rotating ring 21 and a rotating ratchet 312 that is rotatably disposed in the mounting box 321. The locking gear 311 and the rotating ratchet 312 are connected by a rotating shaft. A sliding ratchet 313 that meshes with the rotating ratchet 312 is slidably disposed in the mounting box 321. A spring is provided between the sliding ratchet 313 and the mounting box 321, and it is separated from the rotating ratchet 312.

[0032] In the above description, the sliding ratchet 313 separates from the rotating ratchet 312, and the locking gear 311 rotates with the rotating ring 21. After the U-shaped rod 33 is inserted into the mounting box 321, it pushes the push plate 325 forward through the push rack 327, compressing the telescopic tube 322 and simultaneously pushing the telescopic tube 322 to move. When the U-shaped rod 33 is fully inserted into the mounting box 321, the abutment 323 aligns with the through hole 324, and pushes the sliding ratchet 313 to mesh with the rotating ratchet 312, causing the locking gear to engage. 311 and the rotating ring 21 stop rotating; after the U-shaped rod 33 returns to its original position, the U-shaped rod 33 pulls the push plate 325 backward, and at the same time, the tension spring 332 between the push plate 325 and the telescopic tube 322 is stretched until the push plate 325 drives the telescopic tube 322 to move backward, and after the telescopic tube 322 pulls the stop block 323 out of the through hole 324 through the spring, the telescopic tube 322 is pulled back by the tension spring 332. At the same time, the sliding ratchet 313 separates from the rotating ratchet 312 through the spring, so that the locking gear 311 and the rotating ring 21 resume rotation.

[0033] Combined with appendix Figure 2 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8As shown, the thickness measuring module 4 includes a rotating rod 41 and a thickness measuring rod 413 rotatably mounted on the bracket 7. A torsion spring 411 is provided between the rotating rod 41 and the bracket 7, and a thickness adjustment module 42 connected to the U-shaped rod 33 is provided at the end. One end of the thickness measuring rod 413 is rotatably mounted with a roller 414 that abuts against the winding shaft 11, and the other end is slidably mounted on the rotating rod 41 and rotatably mounted with a connecting sleeve 412 (the connecting sleeve 412 is movably sleeved on the rotating rod 41). The other end of the connecting sleeve 412 is connected by a spacer ring 25.

[0034] Combined with appendix Figure 6 Appendix Figure 7 Appendix Figure 8 As shown, the thickness adjustment module 42 includes an adjustment disc 421 mounted on a rotating rod 41. An adjustment groove 422 is radially arranged on the adjustment disc 421 (the adjustment groove 422 is vertically arranged when the roller 414 abuts against the take-up shaft 11). A positioning bolt 424 is slidably arranged in the adjustment groove 422. A threaded sleeve 423 is threadedly fitted on the positioning bolt 424. A push rod 425 is rotatably arranged on the threaded sleeve 423. The push rod 425 is horizontally arranged and its other end is slidably arranged in a vertical sliding groove 426 vertically arranged on the U-shaped rod 33. The push rod 425 remains horizontal during the sliding process in the vertical sliding groove 426.

[0035] In the above description, the roller 414 abuts against the take-up shaft 11 or the outer side of the base fabric roll via the torsion spring 411. As the thickness of the base fabric roll increases, the thickness measuring rod 413 drives the rotating rod 41 to rotate, and the threaded sleeve 423 moves with the rotating adjusting plate 421, thereby causing the push rod 425 to push the U-shaped rod 33 to move. In this process, in order to ensure that the moving distance of the U-shaped rod 33 remains constant, the position of the threaded sleeve 423 in the adjusting groove 422 is determined by the threaded engagement between the positioning bolt 424 and the threaded sleeve 423. Thus, as the rotating rod 41 rotates at different angles, the left and right moving distance of the push rod 425 is fixed. Specifically, the thickness measuring rod 413 is pulled to the position where the base fabric roll has the maximum thickness, and the U-shaped rod 33 is pushed to be fully inserted into the mounting box 321. At this time, the positioning bolt 424 and the threaded sleeve 423 are threadedly engaged, so that the two are clamped and fixed in the corresponding position of the adjusting groove 422.

[0036] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 10As shown, the cutting module 5 includes a limiting frame 51 corresponding to the base fabric outlet of the limiting roller 71. A gate 52 is slidably mounted on the top of the limiting frame 51, and a transverse rack 53 is slidably mounted on the top. A cutting gear 55 is rotatably mounted and meshes with the transverse rack 53. A pressing rack 54 is mounted on the gate 52 and meshes with the cutting gear 55. A spring is mounted between one end of the transverse rack 53 and the limiting block 56 mounted on the limiting frame 51, and the other end is connected to the spacer ring 25. Adsorption blocks 57 are respectively mounted on the transverse rack 53 and the spacer ring 25, and the two adsorption blocks 57 are positioned correspondingly. After the two adsorption blocks 57 are magnetically attracted together, the transverse rack 53 moves with the spacer ring 25.

[0037] In the above description, the two adsorption blocks 57 are magnetically attracted together, connecting the transverse rack 53 and the spacer ring 25. The spacer ring 25 moves with the pusher plate 22 to the front of the limit baffle 13. The transverse rack 53 moves with the spacer ring 25 and drives the cutting gear 55 to rotate, thereby driving the gate 52 to press down through the pressing rack 54, cutting the base fabric at the limit frame 51. After the transverse rack 53 is blocked by the limit frame 51, the two adsorption blocks 57 separate. The transverse rack 53 is restored by the spring, causing the gate 52 to lift and return to its original position. After the spacer ring 25 moves back with the pusher plate 22, the two adsorption blocks 57 stick together and are adsorbed together again.

[0038] Combined with appendix Figure 1 Appendix Figure 11 As shown, the transfer module 6 includes a transfer slide rail 61 arranged horizontally from left to right and a transfer seat 62 slidably disposed on the transfer slide rail 61. A lifting seat 63 is slidably disposed on the transfer seat 62, and a transfer support shaft 64 is disposed on the lifting seat 63 corresponding to the winding shaft 11. A lifting motor 65 and a lifting screw 66 are disposed on the transfer seat 62. The lifting screw 66 is vertically disposed, and one end is rotatably disposed on a bearing seat reserved on the transfer seat 62, and the other end is connected to the drive shaft of the lifting motor 65. The lifting seat 63 is threadedly sleeved on the lifting screw 66.

[0039] As described above, after the transfer seat 62 moves to one end of the transfer slide rail 61, its transfer support shaft 64 is arranged corresponding to the take-up shaft 11. After the pusher plate 22 pushes the base fabric roll, the base fabric roll leaves the take-up shaft 11 and is sleeved on the transfer support shaft 64, pushing the transfer seat 62 to slide on the transfer slide rail 61. After moving to the storage position, the lifting motor 65 is started to raise and lower the lifting seat 63 and slide the take-up shaft 11 out of the transfer support shaft 64, thereby facilitating the stacking of the base fabric roll. As needed, the existing automatic control system and equipment can be added to the transfer seat 62 to enable the transfer seat 62 to automatically complete the transfer of the base fabric roll. It is worth noting that during the unloading process, the transfer support shaft 64 and the take-up shaft 11 will automatically make minor adjustments to the diameter through the automatic control system to reduce the friction between them and the core.

[0040] In a specific implementation of this invention, the rotating disk 123 is activated, and the winding shaft 11 and the pushing module 2 rotate synchronously with the rotating disk 123. After the conductive PU leather base fabric is produced, it passes through the limiting roller 71 and the cutting module 5 and is wound onto the winding shaft 11. The roller 414 abuts against the outermost surface of the base fabric roll to measure and determine the thickness of the base fabric roll. When the thickness of the base fabric roll reaches the set value, both ends of the U-shaped rod 33 are fully inserted into the mounting box 321, and the abutment block 323 passes through the through hole 324 to press against the sliding ratchet disk 313. The sliding ratchet disk 313 engages with the rotating ratchet disk 312, and the locking gear 311 and the rotating ring 21 are locked, stopping the rotation. The rotating ring 21 rotates relative to the continuing rotating pushing plate 22, causing each extension rod 234 to fold and unfold, pushing the pushing plate 22, and simultaneously rotating with the rotating disk 123. The movement causes the torsion spring 24 to extend and retract, and the pusher plate 22 slides back and forth on the take-up shaft 11. It also drives the transverse rack 53 and the thickness measuring rod 413 to move through the spacer ring 25, thereby controlling the guillotine 52 to press down and cut the base fabric at the limit frame 51. The base fabric roll is then pushed onto the transfer support shaft 64. As the pusher plate 22 slides back and forth on the take-up shaft 11, the roller 414 leaves the base fabric roll on the transfer support shaft 64 and abuts against the take-up shaft 11 through the torsion spring 411, thereby pulling out the U-shaped rod 33. The sliding ratchet 313 separates from the rotating ratchet 312, and the locking gear 311 and the rotating ring 21 resume rotation. The rotating ring 21 rotates in the opposite direction between the torsion spring 24 and the rotating disk 123, causing each extension rod 234 to fold in the opposite direction and unfold, restoring the position and state of the pusher plate 22 and the take-up shaft 11.

[0041] After removing the transfer seat 62, the next roll of conductive PU leather base fabric is wound up and then stacked in the storage location.

[0042] In specific implementations of this invention, the contents not described in detail in this specification are existing technologies known to those skilled in the art.
