Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, specifically to a device for preventing loosening and positioning of enameled round wire coils. Background Technology

[0002] In the wire and cable manufacturing industry, the winding of enameled round wire is a crucial step. Enameled round wire is widely used in various electrical equipment such as motors and transformers, and its winding quality directly affects the performance and reliability of subsequent electrical products. As electrical products develop towards miniaturization and high performance, higher requirements are placed on the winding precision and stability of enameled round wire. Therefore, developing a device that can effectively prevent enameled round wire from loosening and achieve precise winding positioning is of great significance for improving the production quality and efficiency of the wire and cable manufacturing industry.

[0003] In traditional enameled round wire winding, a simple method of connecting a wire spool and a drive shaft is typically used. The spool is directly mounted on the drive shaft, which is rotated by a motor, thus winding the enameled round wire. To secure the spool, a threaded structure is usually installed on the drive shaft, and the position of the spool is fixed by tightening a nut. Simultaneously, the winding equipment is equipped with a wire guiding device, which mainly consists of a reciprocating guide wheel. The guide wheel is driven by a lead screw and moves reciprocally along the axial direction of the spool under the drive of a motor, ensuring that the enameled round wire is evenly wound onto the spool.

[0004] Although traditional methods of winding enameled round wire can achieve the winding process to some extent, in actual production, when the wire spool rotates at high speed, an unavoidable assembly gap (or misalignment) exists between the spool and the drive shaft. This gap causes the spool to wobble during rotation. This wobble prevents the guide wheels of the wire laying device from accurately and evenly laying the enameled round wire onto the spool, resulting in uneven wire laying. Uneven wire laying not only affects the appearance quality of the wound enameled round wire but may also lead to uneven magnetic field distribution within electrical equipment during subsequent use. This uneven distribution can affect equipment performance and, in severe cases, even cause equipment malfunction. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 5 This invention provides an anti-loosening winding positioning device for enameled round wire, including a motor 1. A support base 2 is fixedly connected to the outside of the motor 1. The support base 2 is used to support and fix the motor 1, providing a stable installation foundation for the motor 1 and ensuring that the motor 1 remains stable during operation. A sleeve 14 is fixedly connected to the output end of the motor 1. A fixing rod 10 is slidably connected to the inside of the sleeve 14. A left-right symmetrical limiting block 9 is fixedly connected to the outside of the fixing rod 10. The limiting block 9 is threadedly connected to the inside of the sleeve 14 with a bolt 13. A fixing plate 12 is slidably connected to the other end of the fixing rod 10. A shaft 8 is fixedly connected to the outside of the fixing plate 12. A wire spool 6 is fixedly connected to the outside of the shaft 8. The limiting block 9 is used to fix the relative position of the fixing rod 10 and the sleeve 14, realizing the double-end support and locking of the coil 6 in the axial direction, ensuring the stability of the coil 6 during rotation. Multiple positioning inner support components 11 are provided on the inner side of the shaft 8. The positioning inner support components 11 are used to internally support and position the shaft 8, providing stable support for the coil 6 during rotation and avoiding uneven cable laying caused by assembly misalignment or shaking. An anti-loosening component 7 is provided on the outer side of the fixing plate 12. The anti-loosening component 7 is used to restrict the rotation direction of the coil 6, preventing it from rotating. Rotating in the opposite direction to the wire feeding, and used to press the enameled round wire on the outer periphery of the wire spool 6. The outer side of the shaft 8 is provided with left and right symmetrical disassembly components 4. When the shaft 8 is released from its limiting state, the wire spool 6 can be removed from the support base 2 for replacement. The positioning inner support component 11 includes a third sliding block 1101. The third sliding block 1101 is slidably connected to the inner side of the fixed rod 10. The inner side of the third sliding block 1101 is rotatably connected to a first connecting block 1102. The other end of the first connecting block 1102 is rotatably connected to a second connecting block 1103. A third wedge block 1104 is fixedly connected to the outer side of the second connecting block 1103. An anti-slip pad 1105 is fixedly connected to the top of the third wedge block 1104. A fourth wedge block 1106 is slidably connected to the outer side of the third wedge block 1104. Under the push of the second connecting block 1103, the third wedge block 1104 climbs upward along the inclined surface of the fourth wedge block 1106, thereby causing the top anti-slip pad 1105 to expand radially and tightly abut against the inner wall of the shaft 8, achieving internal support and positioning of the coil 6 and ensuring the stability of the coil 6 rotation. Under the drive of the first connecting block 1102, the second connecting block 1103 pushes the third wedge block 1104 to climb upward along the inclined surface of the fourth wedge block 1106, achieving the radial expansion of the anti-slip pad 1105. The fourth wedge block 1106 is fixedly connected to the outer side of the third wedge block 1104. A third connecting block 1107 is fixedly connected to the outside of the fixed rod 10. A third spring 1108 is fixedly connected to the outside of the third connecting block 1107. The other end of the third spring 1108 is fixedly connected to the outside of the third sliding block 1101. Under the action of centrifugal force, the third sliding block 1101 overcomes the elastic force of the third spring 1108 and slides inside the fixed rod 10, triggering the action of the positioning inner support assembly 11. It is the key triggering component of the positioning inner support assembly 11 in response to centrifugal force. The fourth wedge block 1106 provides a climbing slope for the third wedge block 1104 and guides the movement direction of the third wedge block 1104, so that the third wedge block 1104 can push the anti-slip pad 1105 to expand radially in a predetermined direction, thereby achieving the inner support positioning of the coil 6.

[0023] Specifically, in this device, motor 1 is fixed to support base 2, and its output end is connected to fixed rod 10 through sleeve 14. Limiting block 9, in conjunction with bolt 13, locks the position of fixed rod 10 to achieve axial support. Fixed rod 10 connects fixed plate 12 and shaft 8, which is used to support coil 6. The device also includes disassembly assembly 4 for easy coil replacement, and anti-loosening assembly 7 to prevent coil 6 from reversing or loosening.

[0024] The core positioning inner support assembly 11 is located inside the shaft 8. During operation, the third sliding block 1101 slides against the resistance of the third spring 1108 under centrifugal force, and is linked by the first connecting block 1102 and the second connecting block 1103. This action pushes the third wedge block 1104 up the inclined surface of the fourth wedge block 1106 fixed on the rod, causing the anti-slip pad 1105 at the top to expand radially and tightly abut against the inner wall of the shaft 8. This mechanism effectively eliminates assembly play and wobbling, ensuring the rotational stability of the coil 6 and the uniformity of the cable laying.

[0025] Please see the appendix Figure 1 Appendix Figure 7 Appendix Figure 8 and attached Figure 9In a preferred embodiment of the present invention, the disassembly assembly 4 includes a support plate 401, which is fixedly connected to the outside of the support base 2. A base 5 is fixedly connected to the bottom of the support plate 401. A first fixing block 402 is fixedly connected to the outside of the support plate 401. A sliding rod 403 is slidably connected to the inside of the first fixing block 402. A first wedge block 405 is fixedly connected to one end of the sliding rod 403. A first spring 404 is fixedly connected to the outside of the first wedge block 405. The operator pulls the sliding rod 403 to make it move outward against the resistance of the first spring 404, thereby causing the first wedge block 405 to move. The first spring 404 is fixedly connected to the inner side of the first fixed block 402. The first spring 404 provides a rebound force to the sliding rod 403. When the operator releases the sliding rod 403, the disassembly component 4 automatically resets under the action of the rebound force of the first spring 404, ensuring that the disassembly component 4 can be reused and maintained in normal working condition. The second wedge block 406 is slidably connected to the outer side of the first wedge block 405. Both the first wedge block 405 and the second wedge block 406 are slidably connected to the inner side of the support plate 401. The second wedge block 406 cooperates with the first wedge block 405 and slides out or in from the support plate 401 under the drive of the connecting plate 408. The top of the second wedge block 406 is fixedly connected to the connecting plate 408. The first connecting rod 407 is rotatably connected to the inner side of the connecting plate 408. The first connecting rod 407 is fixedly connected to the inner side of the support plate 401. The positioning rod 409 is fixedly connected to the inner side of the connecting plate 408. The positioning rod 409 is slidably connected to the inner side of the shaft 8. After the disassembly assembly 4 is reset, it is inserted into the groove of the shaft 8, which plays a positioning role for the shaft 8 during the rotation of the coil 6 and maintains the stability of the shaft 8 during the rotation process.

[0026] Specifically, the disassembly assembly 4 includes a support plate 401 fixed to the outside of the support base 2, with a base 5 at its bottom and a first fixing block 402 on its outside.

[0027] In terms of the operating mechanism, a sliding rod 403 is slidably connected inside the first fixed block 402, and a first wedge block 405 is connected to its end. A first spring 404 is provided inside the wedge block 405. When the operator pulls the sliding rod 403 to move against the resistance of the first spring 404, the first wedge block 405 is displaced. After releasing the rod, the component automatically resets using the rebound force of the first spring 404.

[0028] In terms of linkage and positioning, the first wedge block 405 and the second wedge block 406 cooperate and slide within the support plate 401. The second wedge block 406 is connected to a connecting plate 408, which is rotatably connected to the support plate 401 via a first connecting rod 407. A positioning rod 409 is provided inside the connecting plate 408. After resetting, the positioning rod 409 engages with the slide groove of the shaft 8, playing a crucial role in positioning and stabilizing the rotating shaft 8 and the coil 6.

[0029] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 6 and attached Figure 7 In a preferred embodiment of the present invention, the anti-loosening component 7 includes a slide rail 701, which is fixedly connected to the outside of the connecting plate 408. A second fixing block 702 is slidably connected to the outside of the slide rail 701. A first rotating block 703 is rotatably connected to the outside of the second fixing block 702. A first L-shaped block 704 is rotatably connected to the other side of the first rotating block 703. A first sliding block 705 is rotatably connected to one side of the first L-shaped block 704. The first sliding block 705 is slidably connected to the inside of the second fixing block 702. A second rotating block 706 is rotatably connected to the other side of the first L-shaped block 704. The first L-shaped block 704, under the force transmitted by the first rotating block 703 and the second rotating block 706, presses the first sliding block 705, causing the first sliding block 705 to slide within the second fixed block 702, thereby driving the second fixed block 702 to slide downward. The second rotating block 706 is rotatably connected to the other side of the first rotating block 703. A transmission rod 707 is rotatably connected to the inner side of the second rotating block 706. The other end of the transmission rod 707 is fixedly connected to the second L-shaped block 708. The other end of the second L-shaped block 708 is fixedly connected to the pawl 709. A ratchet 714 is fixedly connected to the outer side of the fixed disk 12. A second connecting rod 710 is rotatably connected to the inner side of the pawl 709. The second connecting rod 710 is fixedly connected to the outer side of the connecting plate 408 on the other side. One end of the pawl 709 is provided with a tooth structure that is adapted to the ratchet 714 and abuts against the tooth groove of the ratchet 714. Pawl 709 engages with ratchet 714. When the fixed disc 12 reverses along with the spool 6 and shaft 8, pawl 709 is immediately pre-tightened by the second spring 712 via the second sliding block 711, locking ratchet 714 to prevent spool 6 from rewinding. The second sliding block 711 is slidably connected to the inner side of pawl 709. The top of the second sliding block 711 is fixedly connected to the second spring 712. The other end of the second spring 712 is fixedly connected to a third fixing block 713. A fixing plate 3 is fixedly connected to the outer side of the third fixing block 713. Connected to the outside of the connecting plate 408 on the other side, the bottom of the second fixing block 702 is fixedly connected to a pressure plate 715. The pressure plate 715 is installed directly above the wire reel 6. When the second fixing block 702 slides vertically downward along the slide rail 701, the pressure plate 715 quickly presses down and tightly presses the enameled round wire on the outer periphery of the wire reel 6 to prevent the enameled wire from becoming loose and falling off. Driven by the transmission rod 707 and other components, the second fixing block 702 slides vertically downward along the slide rail 701, driving the pressure plate 715 at the bottom to press down, thereby realizing the pressing operation of the enameled round wire.

[0030] Specifically, the anti-loosening component 7 is designed to prevent the coil 6 from reversing and the enameled wire from coming loose. This component is fixed to the outside of the connecting plate 408 by a slide rail 701, on which a second fixing block 702 is slidably connected.

[0031] Regarding the linkage mechanism, the component includes a multi-stage linkage structure comprising a first rotating block 703, a first L-shaped block 704, a first sliding block 705, and a second rotating block 706. These components cooperate with each other, transmitting motion force through the transmission rod 707 to drive the second fixed block 702 to move within the slide rail 701.

[0032] For the anti-reverse function, the end of the transmission rod 707 is connected to the pawl 709 via the second L-shaped block 708. The pawl 709 engages with the ratchet 714 on the fixed disc 12. When the coil 6 reverses with the fixed disc 12, the pawl 709, under the preload of the second spring 712 and the second sliding block 711, instantly locks the ratchet 714, effectively preventing rewinding.

[0033] In terms of the clamping function, along with the transmission action, the second fixing block 702 drives the bottom pressure plate 715 to slide vertically down along the slide rail 701. The pressure plate 715 is located directly above the wire spool 6, and when it moves down, it can firmly press the enameled round wire on the outer periphery of the wire spool 6 to prevent it from becoming loose and falling off.

[0034] Working principle: When a new enameled round wire spool 6 needs to be loaded, the operator pulls the sliding rod 403 in the disassembly assembly 4, causing it to move outward against the resistance of the first spring 404. This, in turn, causes the first wedge block 405 to displace, disengaging it from the inside of the second wedge block 406. At this time, the connecting plate 408 can rotate around the first connecting rod 407, thereby causing the second wedge block 406 to slide out from the support plate 401, making room for the wire spool 6 to be inserted. The operator first inserts one end of the fixing rod 10 into the fixing plate 12 at one end of the shaft 8, and then places the wire spool 6 and its internal shaft 8 into the symmetrical support seats 2 on both sides. After releasing the sliding rod 403, the disassembly assembly 4 automatically resets under the action of the rebound force of the first spring 404, and the positioning rod 409 snaps into the shaft. Within the groove of rod 8, the stability of shaft 8 during rotation is maintained. Then, in conjunction with the sleeve 14 at the output end of motor 1, the fixing rod 10 and the limiting block 9 are slightly tilted and inserted into the sleeve 14. The sleeve 14 and the fixing rod 10 are then fixed and installed by bolt 13, realizing the double-end support and locking of the coil 6 in the axial direction, and preparing the physical connection for equipment startup. Finally, the connecting plate 408 is rotated around the first connecting rod 407, so that the second wedge block 406 slides back into the support plate 401. The inclined surface at the bottom of the second wedge block 406 cooperates with the inclined surface of the first wedge block 405, causing the first wedge block 405 to temporarily retract. After the second wedge block 406 moves to the appropriate position, the first wedge block 405 is re-engaged into the second wedge block 406, completing the reset and locking of the disassembly component 4. After the device is started, the motor 1 outputs power to drive the sleeve 14, the fixed rod 10 and the shaft 8 to rotate at high speed, entering the winding operation state. As the speed increases, the positioning inner support assembly 11 located inside the shaft 8 is automatically triggered by the centrifugal force. The third sliding block 1101 overcomes the elastic force of the third spring 1108 and slides inside the fixed rod 10. Through the linkage transmission between the first connecting block 1102 and the second connecting block 1103, the third wedge block 1104 is pushed to climb up along the inclined surface of the fourth wedge block 1106. This action causes the anti-slip pad 1105 on the top of the third wedge block 1104 to expand radially and tightly abut against the inner wall of the shaft 8, ensuring that the coil 6 maintains extremely high concentricity and running stability during high-speed rotation, avoiding uneven wire laying caused by assembly misalignment and shaking. When the winding operation ends and the machine stops, or when the wire tension fluctuates and the reel 6 shows a tendency to reverse, the anti-loosening component 7 immediately intervenes and generates a linkage protection effect. Once the fixed plate 12 reverses along with the reel 6 and the shaft 8, the ratchet 714 on the outside of the fixed plate 12 will be immediately locked by the pawl 709 pre-tightened by the second spring 712 through the second sliding block 711. The huge reversing torque generated by the reel 6 is converted into a mechanical force that pushes the pawl 709 to move. This force is transmitted through the linkage mechanism consisting of the second L-shaped block 708, the transmission rod 707, the first rotating block 703, and the second rotating block 706. The transmission and direction conversion ultimately drive the first L-shaped block 704 to press the first sliding block 705, causing the first sliding block 705 to slide within the second fixed block 702. This forces the second fixed block 702 to slide vertically downwards along the slide rail 701, causing the pressure plate 715 at the bottom of the second fixed block 702 to quickly press down and tightly press the enameled round wire on the outer periphery of the spool 6. This mechanism not only effectively prevents the spool 6 from rewinding through the cooperation of the ratchet 714 and the pawl 709, but also uses the reversing torque as a force source to achieve automatic clamping of the wire, fundamentally solving the problem of the enameled wire becoming scattered and falling off due to loosening.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
