Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding machine technology, and in particular to an adhesive tape friction pull-back structure and a winding machine. Background Technology
[0002] A winding machine is a device that winds a wire-like object onto a specific workpiece. It is commonly used for winding copper wire and is used to wind coils of various sizes, such as transformer coils, motor windings, and inductor coils. After the wire core is wound, it needs to be secured with outer wrapping tape.
[0003] Reference patents CN107546033B and CN216471540U disclose a toroidal coil winding machine and a high-capacity wrapping ring, respectively. By replacing the wire storage ring in the toroidal coil winding machine with the high-capacity wrapping ring, the coil can be wound with wrapping tape using a copper wire winding machine.
[0004] However, the above-mentioned wrapping tape winding method is only applicable to wrapping tape without adhesiveness around the coil. When it is necessary to wrap tape with adhesiveness, winding the tape from the tape spool into the tape loop will reduce the adhesiveness of the tape and affect the stability of the tape after it is wrapped around the coil. Utility Model Content
[0005] The purpose of this invention is to provide a sticky tape friction pull-back structure and a winding machine that can wind sticky tape onto a coil and ensure the stability of the tape after it is wound onto the coil.
[0006] In a first aspect, this utility model provides an adhesive tape friction pull-back structure, comprising:
[0007] Mounting panel;
[0008] A rotating ring is rotatably mounted on the mounting panel.
[0009] A fixing seat is rotatably mounted on the rotating ring, and the fixing seat is used to install and fix the packing tape roll.
[0010] A friction element is disposed on the mounting panel. The friction element is arranged in an arc shape and is concentric with the rotating ring.
[0011] The rotating ring can pull the fixed seat to rotate in the forward direction to output the wrapping 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 wrapping tape.
[0012] The adhesive tape friction pull-back structure provided by this utility model securely mounts the tape reel onto the rotating ring via a fixing base. During coil wrapping, one end of the tape is first pulled from the reel and fixed to the coil. Then, the coil and the rotating ring rotate synchronously, causing the tape on the reel to wrap around the coil once. This design avoids the step of pre-winding the tape onto the tape ring, helping to maintain the adhesiveness of the tape and thus enhancing the stability of the tape after winding around the coil.
[0013] Furthermore, this structure features a friction element on the mounting panel. When the mounting base rotates to tension the wrapping tape, the friction element does not contact the mounting base, allowing it to rotate forward and feed the wrapping tape normally to the coil. Conversely, when the mounting base rotates to slack off the wrapping tape, the friction element contacts the mounting base. The mounting base then uses the friction generated by the friction element to rotate in the opposite direction, automatically pulling back and tightening the wrapping tape between the coil and the mounting base. This mechanism helps maintain constant tension in the wrapping tape, reducing uneven tension during winding and thus improving the quality of the coil's wrapping tape winding.
[0014] Furthermore, the fixed base is provided with an annular groove, and the fixed base can rotate with the rotating ring to allow the friction element to extend into the annular groove.
[0015] By employing the above technical solution, an annular groove is designed on the fixed base. By allowing the friction element to penetrate deep into this groove, the contact area between the fixed base and the friction element is significantly increased. This design not only enhances the friction between the two but also ensures that when the strapping tape enters a slack state, the friction element can apply sufficient frictional force to drive the fixed base to rotate in the opposite direction. This improvement helps to enhance the stability of the pull-back operation and ensures the continuity and reliability of the strapping tape winding process.
[0016] Furthermore, the annular groove includes a bottom surface, a first sidewall, and a second sidewall, with the first sidewall and the second sidewall located on opposite sides of the bottom surface; the friction element includes a top surface, a third sidewall, and a fourth sidewall, with the third sidewall and the fourth sidewall located on opposite sides of the top surface, and the bottom surface, the first sidewall, and the second sidewall are respectively able to abut against the corresponding top surface, the third sidewall, and the fourth sidewall.
[0017] Furthermore, the distance between the first sidewall and the second sidewall increases progressively from near the bottom surface to far away from the bottom surface, and the distance between the third sidewall and the fourth sidewall increases progressively from near the top surface to far away from the top surface.
[0018] By adopting the above technical solution, the distance between the first sidewall and the second sidewall is set to increase incrementally, and the distance between the third sidewall and the fourth sidewall is set to increase incrementally, which helps to further increase the contact area between the fixed seat and the friction component and enhance the friction between them.
[0019] Furthermore, the friction element includes an integrally formed fixing plate, a connecting plate, and a friction plate. The fixing plate is located on the side of the mounting panel away from the rotating ring. The mounting panel has a connecting through hole. The connecting plate passes through the connecting through hole. The friction plate is located on the side where the connecting plate passes through the connecting through hole. The friction plate is used to abut against the fixing seat.
[0020] By employing the above technical solution, the fixing plate is positioned on the side of the mounting panel away from the rotating ring, while the friction plate is positioned on the side where the connecting plate passes through the connecting through-hole. This meticulously designed friction component mounting structure makes full use of the space on both sides of the mounting panel, achieving efficient space utilization. This layout helps simplify the friction component structure on the rotating ring side, not only reducing space occupation but also improving the overall structural compactness and space utilization rate.
[0021] Furthermore, it also includes a gear transmission assembly, wherein the rotating ring is provided with an external gear, and the gear transmission assembly meshes with the external gear to drive the rotating ring to rotate on the mounting panel.
[0022] Furthermore, the gear transmission assembly includes an input gear, a first output gear, and a second output gear. The input gear meshes with the first output gear and the second output gear, respectively. The first output gear and the second output gear also mesh with the external gear.
[0023] In this design, the first and second output gears are simultaneously connected to both the input gear and the external gear. This layout provides two power output points for the external gear, effectively enhancing the rotational stability of the rotating ring. This design not only improves rotational efficiency but also ensures the smoothness and reliability of the entire system during operation.
[0024] Furthermore, it also includes a threaded connector and a rotating connector. The fixed base is provided with a mounting through hole, and the rotating connector is rotatably disposed in the mounting through hole. The rotating connector is provided with a first threaded hole, and the rotating ring is provided with a second threaded hole. The threaded connector can pass through the first threaded hole and the second threaded hole in sequence.
[0025] 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, by using threaded connectors that pass sequentially through the first and second threaded holes, a fixed connection between the rotating connector and the rotating ring is achieved. This design allows the fixed seat to not only rotate with the rotating ring, but also to rotate forward relative to the rotating ring under the pull of the strap. Simultaneously, the fixed seat can also rotate in the opposite direction relative to the rotating ring under the frictional force of the friction element.
[0026] Furthermore, the rotating ring is provided with a first feeding notch, the mounting panel is provided with a second feeding notch, and the rotating ring can be rotated to align the first feeding notch with the second feeding notch for the coil to pass through.
[0027] By adopting the above technical solution, the first and second feeding gaps can directly allow the coil to pass through or detach from the rotating ring. The coil that has completed the wrapping tape winding can quickly detach from the rotating ring through the first and second feeding gaps, and the new coil can quickly pass through the first and second feeding gaps into the rotating ring for wrapping tape winding, which helps to improve the winding efficiency.
[0028] Secondly, the present invention provides a winding machine including any of the above-mentioned adhesive tape friction pull-back structures.
[0029] As can be seen from the above, the adhesive tape friction pull-back structure provided by this utility model securely mounts the tape roll onto the rotating ring via a fixing seat. During the coil wrapping operation, one end of the tape is first pulled out from the tape roll and fixed to the coil. Then, the coil and the rotating ring rotate synchronously, causing the tape on the tape roll to wrap around the coil once. This design avoids the step of pre-winding the tape onto the tape ring, helping to maintain the adhesiveness of the tape and thus enhancing the stability of the tape after it is wound onto the coil.
[0030] Furthermore, this structure features a friction element on the mounting panel. When the mounting base rotates to tension the wrapping tape, the friction element does not contact the mounting base, allowing it to rotate forward and feed the wrapping tape normally to the coil. Conversely, when the mounting base rotates to slack off the wrapping tape, the friction element contacts the mounting base. The mounting base then uses the friction generated by the friction element to rotate in the opposite direction, automatically pulling back and tightening the wrapping tape between the coil and the mounting base. This mechanism helps maintain constant tension in the wrapping tape, reducing uneven tension during winding and thus improving the quality of the coil's wrapping tape winding.

Detailed Implementation
[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0040] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0041] The adhesive tape friction pull-back structure disclosed in this utility model is mainly used for winding adhesive tape onto a coil, and can ensure the stability of the tape after winding onto the coil.
[0042] Reference Appendix Figure 1 Appendix Figure 2 In one embodiment, the adhesive tape friction pull-back structure includes a mounting panel 100, a rotating ring 200, a fixing seat 300, and a friction element 400. The rotating ring 200 is rotatably mounted on the mounting panel 100; the fixing seat 300 is rotatably mounted on the rotating ring 200 and is used to mount and fix the tape roll 20; the friction element 400 is mounted on the mounting panel 100, and the friction element 400 is arc-shaped and concentrically arranged with the rotating ring 200; wherein, the rotating ring 200 can pull the fixing seat 300 to rotate forward to output tape to the coil 10; the fixing seat 300 can also rotate with the rotating ring 200 to abut against the friction element 400, and the friction element 400 can drive the fixing seat 300 to rotate in the opposite direction to pull back and tighten the tape.
[0043] Specifically, the forward rotation of the fixed base 300 refers to the rotation direction in which the fixed base 300 drives the tape reel 20 to output the tape outward; the reverse rotation of the fixed base 300 refers to the rotation direction in which the fixed base 300 drives the tape reel 20 to pull back the tape. The reverse rotation is opposite to the forward rotation.
[0044] As can be seen from the above, the adhesive tape friction pull-back structure provided by this utility model securely mounts the tape reel 20 onto the rotating ring 200 via the fixing seat 300. During the tape winding operation of the coil 10, one end of the tape is first pulled out from the tape reel 20 and fixed onto the coil 10. Then, the coil 10 and the rotating ring 200 rotate synchronously, causing the tape on the tape reel 20 to wind around the coil 10 one revolution. This design avoids the step of pre-winding the tape onto the tape ring, helping to maintain the adhesiveness of the tape and thus enhancing the stability of the tape after it is wound onto the coil 10.
[0045] When the tape reel 20 is fixed on the rotating ring 200 and rotates relative to the coil 10, there are a closest point and a farthest point between the tape reel 20 and the coil 10. When the tape reel 20 rotates from the closest point to the farthest point, the tape is in a taut state, and the fixing seat 300 can rotate in the forward direction to output tape to the coil 10 normally. 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 slack state. In this state, the tape winding quality of the coil 10 will decrease due to insufficient tension.
[0046] Therefore, this structure features a friction element 400 on the mounting panel 100. When the fixed base 300 rotates to tension the tape, the friction element 400 does not contact the fixed base 300, allowing the fixed base 300 to rotate forward and feed the tape normally to the coil 10. Conversely, when the fixed base 300 rotates to slack off the tape, the friction element 400 contacts the fixed base 300, and the fixed base 300 uses the friction generated by the friction element 400 to rotate in the opposite direction, automatically pulling back and tightening the tape between the coil 10 and the fixed base 300. This mechanism helps maintain a constant tension in the tape, reduces unevenness during tape winding, and thus improves the tape winding quality of the coil 10.
[0047] Reference Appendix Figure 3 In one embodiment, the fixed base 300 is provided with an annular groove 310, and the fixed base 300 can rotate with the rotating ring 200 to allow the friction member 400 to extend into the annular groove 310.
[0048] By adopting the above technical solution, an annular groove 310 is designed on the fixed base 300. By allowing the friction element 400 to abut against the annular groove 310, the contact area between the fixed base 300 and the friction element 400 is significantly increased. This design not only enhances the friction between the two but also ensures that when the strapping tape enters a slack state, the friction element 400 can apply sufficient frictional force to drive the fixed base 300 to rotate in the opposite direction. This improvement helps to improve the stability of the pull-back operation and ensures the continuity and reliability of the strapping tape winding process.
[0049] In one embodiment, a gear transmission assembly 500 is also included, wherein the rotating ring 200 is provided with an external gear 210, and the output end of the gear transmission assembly 500 meshes with the external gear 210 to drive the rotating ring 200 to rotate on the mounting panel 100.
[0050] 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 meshes with the first output gear 510 and the second output gear 520, respectively. The first output gear 510 and the second output gear 520 also mesh with an external gear 210.
[0051] With the above scheme, the first output gear 510 and the second output gear 520 are simultaneously connected to the input gear 530 and the external gear 210. This layout provides two power output points for the external gear 210, effectively enhancing the rotational stability of the rotating ring 200. This design not only improves rotational efficiency but also ensures the smoothness and reliability of the entire system during operation.
[0052] Reference Appendix Figure 4 Appendix Figure 5 In one embodiment, the annular groove 310 includes a bottom surface 313, a first sidewall 311, and a second sidewall 312, with the first sidewall 311 and the second sidewall 312 located on opposite sides of the bottom surface 313; the friction member 400 includes a top surface 410, a third sidewall 420, and a fourth sidewall 430, with the third sidewall 420 and the fourth sidewall 430 located on opposite sides of the top surface 410; the bottom surface 313, the first sidewall 311, and the second sidewall 312 can respectively abut against the corresponding top surface 410, the third sidewall 420, and the fourth sidewall 430.
[0053] In one embodiment, the distance between the first sidewall 311 and the second sidewall 312 increases from near the bottom surface 313 to away from the bottom surface 313, and the distance between the third sidewall 420 and the fourth sidewall 430 increases from near the top surface 410 to away from the top surface 410.
[0054] By adopting the above technical solution, the distance between the first sidewall 311 and the second sidewall 312 is set to increase, and the distance between the third sidewall 420 and the fourth sidewall 430 is set to increase, which helps to further increase the contact area between the fixed seat 300 and the friction member 400 and enhance the friction between them.
[0055] Reference Appendix Figure 5In one embodiment, it further 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 is rotatably disposed 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.
[0056] 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 rotatable connection between the rotating connector 330 and the fixed seat 300. Furthermore, by having the threaded connector 320 pass sequentially through the first threaded hole 331 and the second threaded hole 220, a fixed connection between the rotating connector 330 and the rotating ring 200 is achieved. This design allows 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. Simultaneously, the fixed seat 300 can also rotate in the opposite direction relative to the rotating ring 200 under the frictional force of the friction element 400.
[0057] Specifically, the fixed base 300 also includes a limiting block 350, which is disposed in the mounting through hole 340 and limits the movement of the rotating connector 330 toward the rotating ring 200.
[0058] In one embodiment, the fixing base 300 includes an integrally formed mounting base 360 and a socket 370. The mounting base 360 is provided with an annular groove 310, and the socket 370 is located on the side of the mounting base 360 away from the rotating ring 200. The socket 370 is used for inserting and fixing the packing tape roll 20.
[0059] Reference Appendix Figure 6 In one embodiment, the friction member 400 includes an integrally formed fixing plate 440, a connecting plate 450, and a friction plate 460. The fixing plate 440 is located on the 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 plate 450 passes through the connecting through hole 110. The friction plate 460 is located on the side where the connecting plate 450 passes through the connecting through hole 110. The friction plate 460 is used to abut against the fixing seat 300.
[0060] By adopting the above technical solution, the fixing plate 440 is arranged on the side of the mounting panel 100 away from the rotating ring 200, while the friction plate 460 is arranged on the side where the connecting plate 450 passes through the connecting through hole 110. This carefully designed mounting structure of the friction component 400 makes full use of the space on both sides of the mounting panel 100, achieving efficient space utilization. This layout helps simplify the structure of the friction component 400 on one side of the rotating ring 200, not only reducing space occupation but also improving the compactness and space utilization of the overall structure.
[0061] 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 so that the coil 10 can be inserted.
[0062] By adopting the above technical solution, the first feeding notch 230 and the second feeding notch 120 can directly allow the coil 10 to pass through or detach from the rotating ring 200. The coil 10 that has completed the wrapping tape winding can quickly detach from the rotating ring 200 through the first feeding notch 230 and the second feeding notch 120. The new coil 10 can quickly pass through the first feeding notch 230 and the second feeding notch 120 to pass through the rotating ring 200 for wrapping tape winding, which helps to improve the efficiency of winding.
