Description

Technical Field

[0001] The invention relates to the technical field of winding machines, and in particular to a viscous tape friction pull-back structure and a winding machine. Background Art

[0002] The winding machine is a device that winds a linear object onto a specific workpiece. It is usually used for winding copper wires. It is used to wind coils of various sizes, transformer coils, motor windings, inductor coils, etc. After the wire core is wound, it needs to be wrapped on the outer surface to fix the winding of the wire core.

[0003] Reference patent number CN107546033B discloses a toroidal coil winding machine, and patent number CN216471540U discloses a large-capacity taping ring. By replacing the wire storage ring in the toroidal coil winding machine with the large-capacity taping ring, the copper wire winding machine of the coil can be used to realize the winding of the tape on the coil (the specific winding process of the tape and the coil can refer to the video named "Real Shot of Prototyping of Gear-Type Toroidal Taping Machine" published by the applicant on the Bilibili platform).

[0004] However, the above-mentioned tape winding method is only applicable to winding non-sticky tape around the coil. When it is necessary to wind a sticky tape, winding the tape from the tape reel into the tape ring will reduce the stickiness of the tape, affecting the stability of the tape after being wound around the coil. Summary of the invention

[0005] The object of the present invention is to provide a sticky tape friction pull-back structure and a winding machine, which can wind the sticky tape onto a coil and ensure the stability of the tape after it is wound on the coil.

[0006] In a first aspect, the present invention provides a viscous tape friction pull-back structure, comprising: Install the panels; A rotating ring rotatably disposed on the mounting panel; A fixed seat, rotatably disposed on the rotating ring, and the fixed seat is used to install and fix the tape reel; A friction member is disposed on the mounting panel, the friction member is disposed in an arc shape, and the friction member is disposed concentrically with the rotating ring; The rotating ring can pull the fixed seat to rotate in the forward direction to output the tape to the coil; the fixed seat can also rotate with the rotating ring to abut against the friction member, and the friction member can drive the fixed seat to rotate in the reverse direction to pull back and tighten the tape.

[0007] The sticky tape friction pull-back structure provided by the present invention securely mounts the tape reel on the rotating ring through a fixing seat. When winding the coil tape, first pull out one end of the tape from the tape reel and fix it on the coil, then the coil and the rotating ring rotate synchronously, driving the tape on the tape reel to wrap around the coil. This design avoids the step of winding the tape around the tape ring in advance, helps maintain the stickiness of the sticky tape, and further enhances the stability of the tape after it is wound around the coil.

[0008] In addition, the present structure is specially provided with a friction member on the mounting panel. When the fixed seat is rotated to make the tape enter a tensioned state, the friction member will not contact the fixed seat, allowing the fixed seat to rotate forward and normally convey the tape to the coil. On the contrary, when the fixed seat is rotated to make the tape enter a relaxed state, the friction member will contact the fixed seat, and the fixed seat will use the friction force generated by the friction member to achieve reverse rotation, automatically pulling back and tightening the tape between the coil and the fixed seat. This mechanism helps to maintain a constant tension of the tape, reduce the uneven tightness of the tape when winding, and thus improve the quality of the coil tape winding.

[0009] Furthermore, an annular groove is provided on the fixing seat, and the fixing seat can rotate along with the rotating ring until the friction member extends into the annular groove.

[0010] By adopting the above technical solution, an annular groove is designed on the fixed seat, and the friction member is made to abut against the annular groove, which significantly increases the contact area between the fixed seat and the friction member. This design not only enhances the friction between the two, but also ensures that when the tape enters a relaxed state, the friction member can exert sufficient friction to drive the fixed seat to rotate in the opposite direction. This improvement helps to improve the stability of the pull-back operation and ensure the continuity and reliability of the tape winding process.

[0011] Further, the annular groove includes a bottom surface, a first side wall and a second side wall, and the first side wall and the second side wall are arranged on opposite sides of the bottom surface; the friction part includes a top surface, a third side wall and a fourth side wall, and the third side wall and the fourth side wall are arranged on opposite sides of the top surface, and the bottom surface, the first side wall and the second side wall can respectively abut against the corresponding top surface, the third side wall and the fourth side wall.

[0012] Furthermore, the distance between the first side wall and the second side wall is gradually increased from close to the bottom surface to far away from the bottom surface, and the distance between the third side wall and the fourth side wall is gradually increased from close to the top surface to far away from the top surface.

[0013] By adopting the above technical solution, the distance between the first side wall and the second side wall is set to be increasing, and the distance between the third side wall and the fourth side wall is set to be increasing, which helps to further increase the contact area between the fixed seat and the friction member and enhance the friction between the two.

[0014] Furthermore, the friction part includes an integrally formed fixed plate, a connecting plate and a friction plate, the fixed plate is arranged on the side of the mounting panel away from the rotating ring, the mounting panel is provided with a connecting through hole, the connecting plate passes through the connecting through hole, the friction plate is arranged on the side of the connecting plate passing through the connecting through hole, and the friction plate is used to abut against the fixed seat.

[0015] By adopting the above technical solution, the fixing plate is arranged on the side of the mounting panel away from the rotating ring, and the friction plate is arranged on the side where the connecting plate passes through the connecting through hole. This carefully designed friction member installation structure fully utilizes the space on the opposite sides of the mounting panel and realizes efficient use of space. Such a layout helps to simplify the friction member structure on one side of the rotating ring, which not only reduces the space occupation, but also improves the compactness and space utilization of the overall structure.

[0016] Furthermore, it also includes a gear transmission assembly, the rotating ring is provided with an external gear, and the gear transmission assembly is meshed with the external gear to drive the rotating ring to rotate on the mounting panel.

[0017] Furthermore, the gear transmission assembly includes an input gear, a first output gear and a second output gear, the input gear is meshed with the first output gear and the second output gear respectively, and the first output gear and the second output gear are also meshed with the external gear.

[0018] With the above solution, the first output gear and the second output gear are connected to the input gear and the outer gear at the same time. This layout provides two power output points for the outer gear, effectively enhancing the rotation stability of the rotating ring. This design not only improves the rotation efficiency, but also ensures the stability and reliability of the entire system during operation.

[0019] Furthermore, it also includes a threaded connector and a rotating connector, the fixed seat is provided with a mounting through hole, the rotating connector can be rotatably arranged in the mounting through hole, the rotating connector is provided with a first threaded hole, the rotating ring is provided with a second threaded hole, and the threaded connector can pass through the first threaded hole and the second threaded hole in sequence.

[0020] By adopting the above technical solution, the rotating connector is designed to be rotatably mounted on the mounting through hole, thereby realizing the rotating connection between the rotating connector and the fixed seat. Furthermore, the rotating connector is fixedly connected to the rotating ring by the threaded connector passing through the first threaded hole and the second threaded hole in sequence. This design enables the fixed seat to not only rotate with the rotating ring, but also rotate forward relative to the rotating ring under the pull of the strap, and at the same time, the fixed seat can also rotate reversely relative to the rotating ring under the friction force of the friction member.

[0021] Furthermore, the rotating ring is provided with a first feed notch, and the mounting panel is provided with a second feed notch, and the rotating ring can be rotated to align the first feed notch with the second feed notch for the coil to pass through.

[0022] By adopting the above technical scheme, the setting of the first feed notch and the second feed notch can directly allow the coil to pass through or detach from the rotating ring. The coil that has completed the tape winding can quickly pass through the first feed notch and the second feed notch to detach from the rotating ring. The new coil can quickly pass through the first feed notch and the second feed notch to pass through the rotating ring for tape winding, which helps to improve the winding work efficiency.

[0023] In a second aspect, the present invention provides a winding machine comprising any of the above-mentioned adhesive tape friction pull-back structures.

[0024] As can be seen from the above, the adhesive tape friction pull-back structure provided by the present invention securely mounts the tape reel on the rotating ring through the fixing seat. When winding the coil tape, first pull out one end of the tape from the tape reel and fix it on the coil, then the coil and the rotating ring rotate synchronously, driving the tape on the tape reel to wrap around the coil. This design avoids the step of winding the tape around the tape ring in advance, helps to maintain the viscosity of the adhesive tape, and further enhances the stability of the tape after it is wound around the coil.

[0025] In addition, the present structure is specially provided with a friction member on the mounting panel. When the fixed seat is rotated to make the tape enter a tensioned state, the friction member will not contact the fixed seat, allowing the fixed seat to rotate forward and normally convey the tape to the coil. On the contrary, when the fixed seat is rotated to make the tape enter a relaxed state, the friction member will contact the fixed seat, and the fixed seat will use the friction force generated by the friction member to achieve reverse rotation, automatically pulling back and tightening the tape between the coil and the fixed seat. This mechanism helps to maintain a constant tension of the tape, reduce the uneven tightness of the tape when winding, and thus improve the quality of the coil tape winding.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0036] The adhesive tape friction pull-back structure disclosed in the present invention is mainly used to wind the adhesive tape around a coil and can ensure the stability of the tape after it is wound around the coil.

[0037] Reference Figure 1 , Attachment Figure 2 In one embodiment, the adhesive tape friction pull-back structure includes a mounting panel 100, a rotating ring 200, a fixed seat 300, and a friction member 400. The rotating ring 200 is rotatably mounted on the mounting panel 100; the fixed seat 300 is rotatably mounted on the rotating ring 200, and the fixed seat 300 is used to mount and fix the tape reel 20; the friction member 400 is mounted on the mounting panel 100, and the friction member 400 is arranged in an arc shape, and the friction member 400 is arranged concentrically with the rotating ring 200; wherein the rotating ring 200 can pull the fixed seat 300 to rotate forwardly to output the tape to the coil 10; the fixed seat 300 can also rotate with the rotating ring 200 to abut against the friction member 400, and the friction member 400 can drive the fixed seat 300 to rotate in the opposite direction to pull back and tighten the tape.

[0038] Specifically, the forward rotation of the fixed seat 300 refers to the rotation direction in which the fixed seat 300 can drive the tape reel 20 to output the tape outward; the reverse rotation of the fixed seat 300 refers to the rotation direction in which the fixed seat 300 can drive the tape reel 20 to pull back the tape, and the reverse rotation is opposite to the forward rotation.

[0039] As can be seen from the above, the adhesive tape friction pull-back structure provided by the present invention securely mounts the tape reel 20 on the rotating ring 200 through the fixing seat 300. When the coil 10 is wound with tape, one end of the tape is first pulled out from the tape reel 20 and fixed on the coil 10, and then the coil 10 and the rotating ring 200 rotate synchronously, driving the tape on the tape reel 20 to wrap around the coil 10. This design avoids the step of winding the tape around the tape ring in advance, helps to maintain the viscosity of the adhesive tape, and further enhances the stability of the tape after it is wound around the coil 10.

[0040] When the tape reel 20 is fixed on the rotating ring 200 and rotated relative to the coil 10 for winding, the distance between the tape reel 20 and the coil 10 has a closest point and a farthest point. When the tape reel 20 rotates from the closest point to the farthest point, the tape is in a tensioned state, and the fixing seat 300 can rotate forward to normally output the tape to the coil 10; however, when the tape reel 20 rotates from the farthest point to the closest point, the tape between the tape reel 20 and the coil 10 will become weak. At this time, the tape is in a relaxed state. In this state, the winding quality of the tape around the coil 10 will be reduced due to insufficient tension.

[0041] Therefore, the present structure is specially provided with a friction member 400 on the mounting panel 100. When the fixing seat 300 rotates to make the tape enter a tensioned state, the friction member 400 will not contact the fixing seat 300, allowing the fixing seat 300 to rotate forward and normally deliver the tape to the coil 10. On the contrary, when the fixing seat 300 rotates to make the tape enter a relaxed state, the friction member 400 will contact the fixing seat 300, and the fixing seat 300 will use the friction force generated by the friction member 400 to achieve reverse rotation, automatically pulling back and tightening the tape between the coil 10 and the fixing seat 300. This mechanism helps to maintain a constant tension of the tape, reduce the uneven tightness of the tape when winding, and thus improve the tape winding quality of the coil 10.

[0042] Reference Figure 3 In one embodiment, an annular groove 310 is provided on the fixing seat 300 , and the fixing seat 300 can rotate along with the rotating ring 200 until the friction member 400 extends into the annular groove 310 .

[0043] By adopting the above technical solution, an annular groove 310 is designed on the fixing seat 300, and the friction member 400 is made to abut against the annular groove 310, which significantly increases the contact area between the fixing seat 300 and the friction member 400. This design not only enhances the friction between the two, but also ensures that when the strap enters a relaxed state, the friction member 400 can exert sufficient friction to drive the fixing seat 300 to rotate in the opposite direction. This improvement helps to improve the stability of the pull-back operation and ensure the continuity and reliability of the strap winding process.

[0044] In one embodiment, a gear transmission assembly 500 is further included. The rotating ring 200 is provided with an external gear 210 . The output end of the gear transmission assembly 500 is meshed with the external gear 210 to drive the rotating ring 200 to rotate on the mounting panel 100 .

[0045] In one embodiment, the gear transmission assembly 500 includes an input gear 530 , a first output gear 510 and a second output gear 520 , the input gear 530 is meshed with the first output gear 510 and the second output gear 520 , respectively, and the first output gear 510 and the second output gear 520 are also meshed with the outer gear 210 .

[0046] With the above solution, the first output gear 510 and the second output gear 520 are connected to the input gear 530 and the outer gear 210 at the same time. This layout provides two power output points for the outer gear 210, effectively enhancing the rotation stability of the rotating ring 200. Such a design not only improves the rotation efficiency, but also ensures the stability and reliability of the entire system during operation.

[0047] Reference Figure 4 , Attachment Figure 5 In one embodiment, the annular groove 310 includes a bottom surface 313, a first side wall 311 and a second side wall 312, and the first side wall 311 and the second side wall 312 are arranged on opposite sides of the bottom surface 313; the friction member 400 includes a top surface 410, a third side wall 420 and a fourth side wall 430, and the third side wall 420 and the fourth side wall 430 are arranged on opposite sides of the top surface 410, and the bottom surface 313, the first side wall 311, and the second side wall 312 can respectively abut against the corresponding top surface 410, the third side wall 420, and the fourth side wall 430.

[0048] In one embodiment, the distance between the first side wall 311 and the second side wall 312 is gradually increased from close to the bottom surface 313 to far away from the bottom surface 313 , and the distance between the third side wall 420 and the fourth side wall 430 is gradually increased from close to the top surface 410 to far away from the top surface 410 .

[0049] By adopting the above technical solution, the distance between the first side wall 311 and the second side wall 312 is set to be increasing, and the distance between the third side wall 420 and the fourth side wall 430 is set to be increasing, which helps to further increase the contact area between the fixing seat 300 and the friction member 400 and enhance the friction between the two.

[0050] Reference Figure 5In one embodiment, it also includes a threaded connector 320 and a rotating connector 330. The fixed base 300 is provided with a mounting through hole 340. The rotating connector 330 can be rotatably arranged in the mounting through hole 340. The rotating connector 330 is provided with a first threaded hole 331. The rotating ring 200 is provided with a second threaded hole 220. The threaded connector 320 can pass through the first threaded hole 331 and the second threaded hole 220 in sequence.

[0051] By adopting the above technical solution, the rotating connector 330 is designed to be rotatably mounted on the mounting through hole 340, thereby realizing the rotating connection between the rotating connector 330 and the fixed seat 300. Furthermore, the rotating connector 330 is fixedly connected to the rotating ring 200 by sequentially passing through the first threaded hole 331 and the second threaded hole 220 by the threaded connector 320. This design enables the fixed seat 300 to not only rotate with the rotating ring 200, but also to rotate forward relative to the rotating ring 200 under the pull of the strap, and at the same time, the fixed seat 300 can also rotate in the opposite direction relative to the rotating ring 200 under the friction force of the friction member 400.

[0052] Specifically, the fixing seat 300 further includes a limiting block 350 , which is disposed in the mounting through hole 340 , and the limiting block 350 limits the movement of the rotating connector 330 toward the rotating ring 200 .

[0053] In one embodiment, the fixing seat 300 includes an integrally formed mounting seat 360 and a socket 370 , the mounting seat 360 is provided with an annular slot 310 , the socket 370 is disposed on a side of the mounting seat 360 away from the rotating ring 200 , and the socket 370 is used for inserting and fixing the tape reel 20 .

[0054] Reference Figure 6 In one embodiment, the friction member 400 includes an integrally formed fixed sheet 440, a connecting sheet 450 and a friction sheet 460. The fixed sheet 440 is disposed on a side of the mounting panel 100 away from the rotating ring 200. The mounting panel 100 is provided with a connecting through hole 110. The connecting sheet 450 passes through the connecting through hole 110. The friction sheet 460 is disposed on a side of the connecting sheet 450 passing through the connecting through hole 110. The friction sheet 460 is used to abut against the fixing seat 300.

[0055] By adopting the above technical solution, the fixing sheet 440 is arranged on the side of the mounting panel 100 away from the rotating ring 200, and the friction sheet 460 is arranged on the side where the connecting sheet 450 passes through the connecting through hole 110. This carefully designed friction member 400 installation structure fully utilizes the space on the opposite sides of the mounting panel 100, and realizes efficient use of space. Such a layout helps to simplify the friction member 400 structure on one side of the rotating ring 200, which not only reduces the space occupation, but also improves the compactness and space utilization of the overall structure.

[0056] In one embodiment, the rotating ring 200 is provided with a first feed notch 230 , and the mounting panel 100 is provided with a second feed notch 120 . The rotating ring 200 can be rotated to align the first feed notch 230 with the second feed notch 120 for the coil 10 to pass through.

[0057] By adopting the above technical solution, the setting of the first feed notch 230 and the second feed notch 120 can directly allow the coil 10 to pass through or detach from the rotating ring 200. The coil 10 that has completed tape winding can quickly pass through the first feed notch 230 and the second feed notch 120 to detach from the rotating ring 200. The new coil 10 can quickly pass through the first feed notch 230 and the second feed notch 120 to pass through the rotating ring 200 for tape winding, which helps to improve winding work efficiency.
