Technical Field

[0001] This invention relates to the field of equipment technology for processing impregnated fabric, and more specifically to an automatic rewinding device for impregnated fabric. Background Technology

[0002] The polymer composite material wedge main friction plate is a component of railway freight cars. Installed within the wedge body of the friction damping device on the freight car bogie, its function is to increase the rotational damping of the bogie and car body, ensuring safe operation and suppressing the bogie and car body's swaying and serpentine movements. A positioning dome is located in the middle of the main friction plate. During production, a roll of impregnated fabric is automatically slit into narrow rolls. These narrow rolls are then manually rolled into cylinders matching the shape of the positioning dome and secured with rope, completing the initial fabrication. This process requires significant manual labor for winding, increasing the factory's labor costs. Furthermore, the diameter and tightness of manually wound finished products cannot be guaranteed, affecting product quality and yield. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the invention will be described clearly and completely below in conjunction with specific embodiments.

[0031] An automatic rewinding device for impregnated fabric, such as Figure 1 , Figure 2 , Figure 5 As shown, it includes: a support 1, a feeding tray 2, a cutting mechanism 5, and a winding and unloading mechanism 6. The feeding tray 2 is located at one end of the support 1. The feeding tray 2 is driven by the winding and unloading mechanism 6 when it pulls the impregnated cloth. The feeding tray 2 is equipped with a brake part 3 to stop the feeding tray 2. The lower part of the feeding tray 2 is equipped with a correction part 4 to assist the feeding tray 2 in correction, thus ensuring the stability of the equipment operation.

[0032] like Figure 3 , Figure 4 As shown, the correction unit 4 includes: a first sliding frame 41, a second sliding frame 42, a lead screw 43, a lead screw nut 44, and a first motor 45. The first sliding frame 41 is fixedly connected to the bracket 1. The upper part of the first sliding frame 41 is provided with a protrusion 411, and the lower part of the second sliding frame 42 is provided with a groove 421. The protrusion 411 and the groove 421 cooperate to allow the second sliding frame 42 to slide on the first sliding frame 41. The upper part of the second sliding frame 42 is fixedly connected to the feeding plate 2 and the brake unit 3. The lead screw 43 passes through the interior of the first sliding frame 41. The lead screw 44 is sleeved on the lead screw 43 and is fixedly connected to the second sliding frame 42. The end of the lead screw 43 is provided with a first pulley 46. The output shaft of the first motor 45 is provided with a second pulley 47. The first motor 45 is a forward and reverse motor and is fixedly connected to the bracket 1. The first pulley 46 and the second pulley 47 are driven by a first belt 48. The side of the second sliding frame 42 is provided with two limit plates 49. The bracket 1 is provided with two limit switches 410 corresponding to the two limit plates 49 respectively.

[0033] During the automatic slitting and winding process, there is an offset between each layer of the narrow roll of dipped fabric. Since subsequent processes require alignment of the dipped fabric, and the lead screw 43, lead nut 44 transmission structure, and first motor 45 do not have self-locking mechanisms, the first sliding frame 41 and the second sliding frame 42 can slide relative to each other to compensate for the offset of the dipped fabric and prevent conflicts between the two processes, thus affecting the processing of each process. When the offset is too large, the limit plate 49 on the second sliding frame 42 will contact the limit switch 410 on the bracket 1. The limit switch 410 releases an electrical signal to control the first motor 45 to drive the lead screw 43 to rotate. The lead nut 44 cooperates with the lead screw 43 to make the second sliding frame 42 translate, compensating for the offset and resetting the second sliding frame 42. This prevents the second sliding frame 42 from being unable to be pulled back to the correct position during the alignment operation of subsequent processes if the offset is too large, thus affecting the processing of the product.

[0034] One side of the feeding tray 2 is rotatably connected to the second sliding frame 42. The brake part 3 includes: an electromagnetic powder clutch 31, a first gear 32, and a second gear 33. The electromagnetic powder clutch 31 is fixedly connected to the second sliding frame 42. The input shaft of the electromagnetic powder clutch 31 is fixedly connected to the first gear 32. The second gear 33 is connected to the feeding tray 2. The first gear 32 and the second gear 33 mesh and drive each other. A threaded rod 21 is provided on the other side of the feeding tray 2. A fixing ring 22 is screwed on the threaded rod 21 to fix the take-up frame of the dipped cloth.

[0035] A narrow roll of dipped fabric is fitted onto a threaded rod 21 located on the side of the feeding tray 2. Tightening the retaining ring 22 moves the retaining ring 22 and the threaded rod 21 closer to the feeding tray 2, thus fixing the narrow roll of dipped fabric onto the feeding tray 2. One end of the dipped narrow roll of fabric is manually fed into the subsequent process. Under the pulling force of the subsequent process, the feeding tray 2 rotates with the dipped fabric. When an emergency stop is required, the electromagnetic powder clutch 31 brakes, and the rotation of the feeding tray 2 is restricted through the first gear 32 and the second gear 33.

[0036] like Figure 6 , Figure 7 As shown, the cutting mechanism 5 is located in the middle of the support 1. Multiple guide rollers 7 are provided between the feeding tray 2 and the cutting mechanism 5. The guide rollers 7 include four rollers, which are evenly distributed along the support 1 from the feeding tray 2 to the cutting mechanism 5. They are arranged in a high-low order and are used to accurately place the dipped cloth conveyed by the feeding tray 2 into the cutting mechanism 5.

[0037] The winding and unloading mechanism 6 is located at the other end of the bracket 1. The cutting mechanism 5 works in conjunction with the winding and unloading mechanism 6. When the winding length of the dipped cloth reaches the preset value, the cutting mechanism 5 cuts the dipped cloth raw material fed into the feeding tray 2.

[0038] The cutting mechanism 5 includes a cutting platform 51, a first clamping part 52, a second clamping part 53, and a cutting part 54. A pressing roller 58 is provided at one end of the cutting platform 51. The pressing roller 58 is rotatably connected to the cutting platform 51 and is used to receive the impregnated cloth fed by the guide roller 7. A plurality of guide discs 56 are rotatably connected to the cutting platform 51. The guide discs 56 are arranged in an array on the cutting platform 51. The pressing roller 58 and the guide discs 56 are used to limit the running direction of the impregnated cloth between the guide roller 7 and the first clamping part 52. The first clamping part 52, the cutting part 54, and the second clamping part 53 are sequentially arranged at the other end of the cutting platform 51.

[0039] The first clamping part 52 includes: a first cylinder 521, a first active conveying roller 522, and a first passive conveying roller 523. The first active conveying roller 522 is rotatably connected to the cutting platform 51, and the upper part of the first active conveying roller 522 protrudes from the cutting platform 51. The first active conveying roller 522 is driven to rotate by a second motor 524. The first cylinder 521 is located directly above the first active conveying roller 522 and is fixedly connected to the cutting platform 51. A first frame 525 is provided on the piston rod of the first cylinder 521. The first passive conveying roller 523 is rotatably connected to the frame. The first cylinder 521 can drive the first passive conveying roller 523 to move vertically and control whether the first passive conveying roller 523 contacts the first active conveying roller 522.

[0040] The second clamping part 53 includes: a second cylinder 531, a second active conveying roller 532, and a second passive conveying roller 533. The second active conveying roller 532 is rotatably connected to the cutting platform 51 and is driven to rotate by a third motor 534. The second cylinder 531 is located directly above the second active conveying roller 532 and is fixedly connected to the cutting platform 51. A second frame 535 is provided on the piston rod of the second cylinder 531. The second passive conveying roller 533 is rotatably connected to the second frame 535. The second cylinder can drive the second passive conveying roller 533 to move vertically and control whether the second passive conveying roller 533 contacts the second active conveying roller 532.

[0041] The second motor 524 and the third motor 534 are hidden inside the housing on the bracket 1 for storing the wires.

[0042] The cutting part 54 is disposed between the first clamping part 52 and the second clamping part 53. The cutting part 54 includes a cutting cylinder 541 and a cutter 542. The cutting cylinder 541 is fixedly connected to the cutting platform 51, and the cutter 542 is fixedly connected to the piston rod of the cutting cylinder 541.

[0043] When the roll of dipped fabric on the winding and unloading mechanism 6 reaches the preset diameter, the winding and unloading mechanism 6 controls the electromagnetic powder clutch 31 to brake via an electrical signal, stopping the feeding disc 2. The first cylinder 521 and the second cylinder 531 work simultaneously, driving the first passive conveying roller 523 and the second passive conveying roller 533 downwards, respectively contacting the first active roller and the second active conveying roller 532. The first active conveying roller 522 rotates towards the feeding disc 2 under the drive of the second motor 524, and the second active conveying roller 532 rotates towards the winding and unloading mechanism 6 under the drive of the third motor 534, thereby stretching the dipped fabric located between the first active conveying roller 522 and the second active conveying roller 532 to a horizontal position. The cutting cylinder 541 then operates, driving the cutter 542. Cutting along the vertical direction of the impregnated fabric, the impregnated fabric is cut off. The second cylinder 531 lifts the second passive conveyor roller 533, while the first cylinder 521 remains stationary. After the winding and unloading mechanism 6 completes its process, the first active conveyor roller 522 and the second active conveyor roller 532 rotate simultaneously toward the winding and unloading mechanism 6. The first active conveyor roller 522 and the first passive conveyor roller 523 convey the impregnated fabric below them to the position of the second active conveyor roller 532. The second cylinder 531 drives the second passive conveyor roller 533 to fall, so that the second active conveyor roller 532 and the second passive roller cooperate to send the impregnated fabric into the winding and unloading mechanism 6. The first cylinder 521 and the second cylinder 531 drive the first passive conveyor roller 523 and the second passive conveyor roller 533 to move upward in sequence.

[0044] like Figures 8-10 As shown, the winding and unloading mechanism 6 includes: a feeding auxiliary part 61, a winding part 62, and an unloading part 63. The feeding auxiliary part 61 is used to assist the dipped cloth in entering the winding part 62. The winding part 62 is used to wind up the dipped cloth conveyed by the cutting mechanism 5. The unloading part 63 is located on the opposite side of the winding part 62 and is used to fix and unload the wound dipped cloth.

[0045] The feeding auxiliary unit 61 includes: an auxiliary cylinder 611, a cleaning brush 612, an auxiliary frame 613, and an auxiliary motor 614. The auxiliary frame 613 is fixedly connected to the support 1, and the cleaning brush 612 is rotatably connected to the auxiliary frame 613. The cleaning brush 612 is driven by the auxiliary motor 614. The auxiliary cylinder 611 is located below the auxiliary frame 613 and is fixedly connected to the support 1. An auxiliary platform 615 is provided on the piston rod of the auxiliary cylinder 611. The auxiliary platform 615 moves vertically under the push of the auxiliary cylinder 611. When the auxiliary platform 615 is in contact with the cleaning brush 612, the auxiliary motor 614 drives the cleaning brush 612 to rotate, which is used to receive the dipped cloth from the previous process and send it into the next process. At the same time, the cleaning brush 612 can clean the surface of the dipped cloth, making it tighter when rolled up, thus ensuring the quality of the finished product.

[0046] When the second cylinder 531 drives the second passive conveying roller 533 to move downward, the auxiliary cylinder 611 drives the auxiliary platform 615 to move upward and abut against the cleaning brush 612. The auxiliary motor 614 drives the cleaning brush 612 to rotate, receive the impregnated cloth and send it into the winding section 62. After the winding section 62 has finished receiving it, the auxiliary cylinder 611 drives the auxiliary platform 615 to move downward and disengage from the cleaning brush 612.

[0047] The winding section 62 includes: a first support base 621, a third cylinder 622, a fourth cylinder 623, a drive shaft 624, and a winding motor 625. The first support base 621 is movably connected to the bracket 1 via a first linear slide rail 626 and a first linear slider 627. The third cylinder 622 drives the first support base 621 to move. When the third cylinder 622 drives the first support base 621 to move closer to the feeding auxiliary section 61, it receives the dipped fabric fed by the feeding auxiliary section 61. After receiving, the third cylinder 622 drives the first support base 621 to move away from the feeding auxiliary section 61. The fourth cylinder 623 is fixedly connected to the first support base 621. A discharge plate 628 is provided on the piston of the fourth cylinder 623. Four cylinders 623 drive the movement of the unloading plate 628, which assists in unloading. A take-up motor 625 is fixedly connected to the first support base 621, and a drive shaft 624 is rotatably connected to the first support base 621. A third pulley 629 is fixedly mounted on the output shaft of the take-up motor 625, and a fourth pulley 6210 is mounted at one end of the drive shaft 624. The third pulley 629 and the fourth pulley 6210 are driven by a second belt 6211. A support pulley 6212 is provided at the tail of the take-up motor 625 to support it and prevent damage from vigorous movement. A first take-up rod 6213 and a second take-up rod 6214 are mounted on the other end face of the drive shaft 624. Figure 11 As shown, the first winding rod 6213 and the second winding rod 6214 are both inserted into the unloading plate 628. The first winding rod 6213 is located at the center of the end face, and the second winding rod 6214 is located at the eccentric position of the end face. The unloading plate 628 is provided with a pressing block 6215. The winding motor 625 drives the drive shaft 624 to rotate through the third pulley 629 and the fourth pulley 6210, thereby driving the first winding rod 6213 and the second winding rod 6214 to rotate, which is used to wind up the dipped fabric. The pressing block 6215 is used to temporarily press the end of the wound dipped fabric roll to prevent it from falling apart. The unloading plate 628 is also provided with a diameter detection module 6216, which is an infrared distance detection module, used to detect the diameter of the dipped fabric roll wound on the first winding rod 6213 and the second winding rod 6214.

[0048] The drive shaft 624 has an indicator plate 6217 on one end face of the fourth pulley 6210, and the first support 621 has a position detection module 6218. The indicator plate 6217 and the position detection module 6218 cooperate to monitor and adjust the position of the winding rod.

[0049] When the feeding auxiliary unit 61 feeds the dipped fabric into the winding unit 62, the third cylinder 622 drives the first support base 621 to move closer to the feeding auxiliary unit 61 to receive the dipped fabric. After the dipped fabric enters between the first winding rod 6213 and the second winding rod 6214, the winding motor 625 drives the first winding rod 6213 and the second winding rod 6214 to rotate, so that the end of the dipped fabric is sleeved onto the first winding rod 6213 and the second winding rod 6214 and fixed, completing the reception of the dipped fabric; the winding motor 625 drives the first winding rod 6213 to rotate. The winding rod 6213 and the second winding rod 6214 rotate continuously. The third cylinder 622 drives the first support seat 621 to move away from the feeding auxiliary part 61 and continues to wind up. When the diameter detection module 6216 detects that the diameter of the completed winding of the dipped cloth roll reaches the preset value, it controls the winding motor 625 to turn off through an electrical signal and drives the cutting mechanism 5 to cut the dipped cloth. After the cutting mechanism 5 completes the cutting, the winding motor 625 turns on and winds up the ends of the dipped cloth located in the cutting mechanism 5 and the feeding auxiliary part 61.

[0050] The unloading section 63 includes: a second support base 631, a finger cylinder 632, a fifth cylinder 633, an unloading cylinder 634, and a pneumatic nail gun 635. The second support base 631 is movably connected to the bracket 1 via a second linear slide rail 636 and a second linear slider 637. The fifth cylinder 633 is used to drive the second support base 631 to move along the direction of the second linear slide rail 636. The finger cylinder 632 is disposed on the upper part of the second support base 631 and corresponds to the position of the winding rod. The piston rod of the finger cylinder 632 is provided with an arc-shaped baffle 638 on its side, which is used to cooperate with the dipped fabric roll to prevent the dipped fabric roll from falling and to make the clamping more stable. The pneumatic nail gun 635 is fixedly disposed on the bracket 1 and is used to insert nails into the dipped fabric roll clamped by the finger cylinder 632 for fixing. The unloading cylinder 634 is fixedly connected to the bracket 1 and is used to push the dipped fabric clamped on the finger cylinder 632 off.
