Description

Technical Field

[0001] This invention relates to the field of take-up machine technology, specifically to a take-up machine for enameled round wire with an elastic wire pressing function. Background Technology

[0002] Enamelled round wire is a core conductive component in power electronic equipment such as motors, transformers, and electronic components. In its production, the winding process is crucial for ensuring product quality and improving production continuity. The winding machine, as the core equipment in this process, is mainly used to neatly and tightly wind the enamelled round wire, after processes such as coating and curing, onto a winding spool for subsequent storage, transportation, and processing. With the rapid development of the power electronics industry, the production scale of enamelled round wire is constantly expanding, placing higher demands on the operating efficiency, automation level, and ease of operation of winding machines. Therefore, developing an enamelled round wire winding machine with elastic wire pressing function that can achieve efficient and automated operation has become an important direction for meeting industry production needs and promoting the upgrading of enamelled round wire production.

[0003] Currently, existing enameled round wire take-up machines mainly consist of a take-up mechanism, a transmission mechanism, and a frame. Their core working principle involves a motor driving the transmission mechanism to rotate the take-up shaft. The rotational traction of the take-up shaft gradually winds up the enameled round wire. Some take-up machines are equipped with simple guide structures to assist in the even winding of the enameled round wire. The clamping of the take-up shaft and the unloading after winding are mainly completed manually with the help of simple mechanical structures. The transmission mechanism uses a single motor to drive the take-up shaft to achieve the basic winding function. The overall structure is relatively simple and suitable for small-scale, low-efficiency enameled round wire production scenarios.

[0004] However, existing enameled round wire take-up machines have significant efficiency bottlenecks in actual production applications, especially in the take-up spool unloading stage after winding. Due to the limitations of the existing mechanical structure design, automatic unloading of the take-up spool is not possible. Manual intervention is required to complete the clamping and releasing operation of the take-up spool. The take-up spool with the wound enameled round wire is manually removed from the take-up mechanism, and a new empty take-up spool is installed and manually clamped and fixed. The entire unloading and resetting process is time-consuming and cumbersome, which seriously affects the cyclic operation efficiency of the take-up machine. It cannot meet the needs of large-scale, high-efficiency enameled round wire production, increases the labor intensity of manual labor, and also restricts the overall improvement of the operating efficiency of the entire enameled round wire winding production line. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an enameled round wire take-up machine with an elastic wire pressing function, which solves the problems of existing enameled round wire take-up machines requiring manual intervention for clamping and loosening during winding and unwinding, resulting in low efficiency in cyclical operations and an inability to adapt to large-scale, high-efficiency production.

[0009] Preferably, the pressing assembly includes a movable base, which is slidably connected to the outer periphery of the second lead screw.

[0016] This invention provides a take-up machine for enameled round wire with an elastic wire-pressing function. It has the following beneficial effects: 1. This invention uses a first motor to drive a rotating shaft, gears, a turntable, and a rotating plate, which in turn causes the slider to slide down and the limit ball to slide out of the limit groove to release the lock. At the same time, the gear and rack meshing pushes the bracket to slide, realizing automatic unloading of the take-up shaft. The motor reverses to complete the mechanism reset cycle. This invention improves the problems of traditional winding and unloading requiring manual intervention for clamping and loosening, and low efficiency of cycle operation, thus improving the overall operating efficiency of the winding production line.

[0017] 2. This invention drives the first lead screw to rotate by rotating the knob, causing the outer shell to slide along the rotating rod. This, in conjunction with the second rotating plate, causes multiple inner support plates to expand outward. At the same time, the second sliding block at the bottom of the inner support plate slides along the slot of the slotted plate to achieve clamping and fixing of the inner support of the take-up shaft. This invention improves the problems of cumbersome operation and uneven clamping force leading to slippage in traditional take-up shaft clamping mechanisms, and enhances the convenience and stability of take-up shaft clamping.

[0018] 3. This invention adjusts the tightness of the bolt by rotating the wing nut, which drives the pulley to move and lock within the deflection plate groove. The enameled wire is guided to the take-up shaft via the double pulleys. Simultaneously, the second lead screw drives the moving seat to move left and right to achieve uniform take-up. When the take-up speed is too slow and the tension is too tight, the tension causes the deflection plate to rotate around the fixed rod. The connecting block at the bottom of the plate abuts against the second spring and elastically presses down to buffer the tension. This invention improves the problem of the traditional enameled wire taking-up tension being unadjustable and the wire breaking due to excessive tension, thus enhancing the stability of the taking-up operation.

[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 9 This invention provides an enameled round wire take-up machine with elastic pressing function, including a base 1. A feeding component 3 is fixedly connected to the top of the base 1. The feeding component 3 is used to automatically unload the take-up shaft 4. The feeding component 3 automatically unloads and resets the take-up shaft 4 through a combination of lifting and sliding drive. Its core function is to replace the traditional manual unloading method, reduce the intensity of manual operation, avoid wear and scratches to the enameled wire during manual unloading, and improve unloading efficiency, adapting to the continuous operation requirements of automated production lines. A slide rail 13 is fixedly connected to the top of the base 1. A bracket 2 is slidably connected to the outside of the slide rail 13. An inner support component 5 is set inside the bracket 2. The inner support component 5 slides up and down inside the bracket 2 to adjust the height position of the take-up shaft 4, ensuring that the take-up shaft 4 corresponds with the pressing component 9 and the enameled wire conveying path, ensuring the smoothness of pressing and take-up. The inner support component 5 stabilizes the take-up shaft 4 coaxially and centrally through an adaptive clamping method. The clamping and inner support assembly 5 is used to fix and clamp take-up spools 4 of different sizes. Its function is to adapt to various specifications of take-up spools 4 without changing special clamps, reducing equipment operating costs. At the same time, it clamps firmly to prevent the take-up spool 4 from rotating, shifting or loosening during the take-up process, ensuring that the enameled wire is wound neatly and tightly. The top of the base 1 is fixedly connected to the fixing seat 6. The fixing seat 6 is rotatably connected to the second lead screw 8. The outer side of the second lead screw 8 is provided with the wire pressing assembly 9. The wire pressing assembly 9 guides the enameled wire smoothly and winds it evenly through tension buffer control. The core function of the wire pressing assembly 9 is to provide continuous and uniform elastic pressure during the winding of the enameled wire, to prevent the enameled wire from being wound too loosely and falling off. At the same time, it prevents the excessive pressure from scratching the insulation layer on the surface of the enameled wire, ensuring the regularity of the enameled wire and the product quality after winding. The top of the base 1 is fixedly connected to the support frame 10. The outer side of the support frame 10 is rotatably connected to the pay-off spool 11. The top of the base 1 is fixedly connected to the control box 12.

[0023] Please see the appendix Figure 2 - Appendix Figure 5In a preferred embodiment of the present invention, the feeding assembly 3 includes a support plate 31. The support plate 31 serves as the core support component of the feeding assembly 3, and is used to install all feeding-related components such as the placement plate 34, the first rotating plate 32, and the connecting plate 314, providing stable installation support points for each component and ensuring the stability of the feeding assembly 3 when all components work together. The support plate 31 is fixedly connected to the top of the base 1, and the placement plate 34 is fixedly connected to the outside of the support plate 31. The top of the placement plate 34 is fixedly connected to the first motor 33, and the output end of the first motor 33 is fixedly connected to a rotating shaft 35. The rotating shaft 35 is used to transmit the driving force of the first motor 33, with one end driving the turntable 36 to rotate and the other end driving the gear 312 synchronously. The rotation enables the distribution and transmission of power, ensuring the synchronicity of the movement of the turntable 36 and the gear 312, thereby guaranteeing the coordinated action of each movement of the unloading assembly 3. One end of the rotating shaft 35 passes through the support plate 31 and is fixedly connected to the turntable 36. The first sliding block 37 serves as a motion transmission component, connecting the turntable 36 and the first rotating plate 32, converting the rotational motion of the turntable 36 into the rotational motion of the first rotating plate 32. It can also slide flexibly on the outside of the turntable 36 and inside the first rotating plate 32, avoiding motion interference and ensuring smooth power transmission. The first sliding block 37 is rotatably connected to the outside of the turntable 36, and the first rotating plate 32 is rotatably connected to the outside of the support plate 31. The first rotating plate 32 is used to transmit the power from the first sliding block. The movement of 37, through its reciprocating rotation, drives the slider 38 to slide up and down inside the bracket 2, thereby driving the inner support assembly 5 and the take-up shaft 4 to move up and down, completing the unloading action of the take-up shaft 4; the bracket 2 is provided with a limit ball 311, which, together with the limit groove 39 and the first spring 310, limits and fixes the slider 38, restricting the sliding position of the slider 38 inside the bracket 2, ensuring that the slider 38 remains stable during the take-up process and does not slide accidentally, thus ensuring the accurate take-up position of the take-up shaft 4; the first spring 310 is fixedly connected to the outside of the limit ball 311, and the slider 38 is slidably connected inside the bracket 2, with a limit groove 39 on the outside of the slider 38, and the rotating shaft 3 A gear 312 is fixedly connected to the outer periphery of the support plate 31. The gear 312 is used to convert the rotational motion of the shaft 35 into the linear sliding motion of the rack 313. Through the meshing transmission of the gear 312 and the rack 313, the connecting plate 314 is driven to slide up and down, thereby driving the bracket 2 to slide along the slide rail 13. The connecting plate 314 is slidably connected to the outer side of the support plate 31. The rack 313 is fixedly connected to the bottom of the connecting plate 314. The rack 313 meshes with the gear 312. As a motion transmission component, it converts the rotational motion of the gear 312 into its own linear sliding motion, thereby driving the connecting plate 314 and the bracket 2 to move synchronously. The gear 312 meshes with the rack 313, and the outer side of the connecting plate 314 contacts the bracket 2. The end of the first spring 310 furthest from the limiting ball 311 is fixedly connected inside the bracket 2 to fix the installation position of the first spring 310, ensuring that the first spring 310 can provide a stable elastic force to the limiting ball 311, while limiting the deformation direction of the first spring 310 to prevent the first spring 310 from shifting laterally and ensuring the accurate movement trajectory of the limiting ball 311; the limiting ball 311 is slidably connected inside the limiting groove 39; the first sliding block 37 is slidably connected inside the first rotating plate 32, and the other end of the first rotating plate 32 is slidably connected inside the slider 38. The sliding cooperation between the first sliding block 37 and the first rotating plate 32, and between the first rotating plate 32 and the slider 38, constitutes a multi-link transmission structure, which is used to smoothly convert the rotational motion of the turntable 36 into the up-and-down reciprocating sliding motion of the slider 38. The transmission process is smooth and without jamming, ensuring that the slider 38 drives the take-up shaft 4 to rise and fall smoothly, avoiding shaking or deviation of the take-up shaft 4 during the rise and fall, and protecting the enameled wire from damage.

[0024] Please see the appendix Figure 6 - Appendix Figure 7In a preferred embodiment of the present invention, the inner support assembly 5 includes a first lead screw 51 and a take-up shaft 4. The first lead screw 51 is disposed inside the take-up shaft 4. A housing 52 is threadedly connected to the outer side of the first lead screw 51, and a rotating rod 53 is slidably connected to the inner side of the housing 52. The rotating rod 53 is used to transmit the driving force of the second motor 58, driving the housing 52, the inner support plate 55, and other components to rotate synchronously, thereby driving the take-up shaft 4 to rotate, realizing the winding action of the enameled wire. At the same time, it allows the housing 52 to slide along its axial direction without affecting the expansion and adjustment of the inner support plate 55. A slotted plate 54 is fixedly connected to one end of the rotating rod 53. The slotted plate 54 is used to install a second sliding block 57, providing sliding guidance for the second sliding block 57 and restricting the movement of the second sliding block 57. The movement trajectory ensures that the second sliding block 57 can slide smoothly along the length direction of the slotted plate 54, thereby driving the inner support plate 55 to expand or contract smoothly. Multiple second rotating plates 56 are rotatably connected to the outer side of the outer shell 52. The second rotating plates 56 connect the outer shell 52 and the inner support plate 55, converting the axial sliding motion of the outer shell 52 into the radial expansion or contraction motion of the inner support plate 55. The synchronous rotation of the multiple second rotating plates 56 ensures that the multiple inner support plates 55 move synchronously, achieving uniform clamping of the inner wall of the take-up shaft 4. Multiple second sliding blocks 57 are slidably connected inside the slotted plate 54. The second sliding blocks 57 connect the slotted plate 54 and the inner support plate 55, sliding inside the slotted plate 54 following the radial movement of the inner support plate 55. To prevent interference during the movement of the inner support plate 55 and ensure its smooth and stable expansion and contraction, multiple inner support plates 55 are rotatably connected to the outer sides of multiple second sliding blocks 57. These inner support plates 55 directly contact the inner wall of the take-up shaft 4, fixing it in place through the clamping force generated by radial expansion. The number of inner support plates 55 can be adjusted according to the size of the take-up shaft 4 to ensure the stability and uniformity of the clamping. Simultaneously, anti-slip textures can be provided on the surface of the inner support plates 55 to increase friction with the inner wall of the take-up shaft 4 and prevent slippage during rotation. A second motor 58 is fixedly connected to the outer side of the slider 38, and the output end of the second motor 58 is fixedly connected to one end of the rotating rod 53. The second rotating plate 56 is located away from the outer casing 52. One end is rotatably connected to the outside of the inner support plate 55, forming a multi-link transmission structure. This ensures that the axial sliding of the outer shell 52 can be synchronously transmitted to each inner support plate 55, causing multiple inner support plates 55 to expand or contract synchronously. This achieves uniform clamping of the inner wall of the take-up shaft 4, preventing the take-up shaft 4 from becoming loose due to uneven force on the inner support plates 55. The first lead screw 51 is slidably connected inside the rotating rod 53. One end of the first lead screw 51 is fixedly connected to a knob 59. Multiple inner support plates 55 are in contact with the inner side of the take-up shaft 4. Through the radial expansion of the inner support plates 55, they fit tightly against the inner wall of the take-up shaft 4, generating sufficient clamping force to firmly fix the take-up shaft 4. This prevents the take-up shaft 4 from rotating or loosening during the take-up process, ensuring that the enameled wire is neatly wound.

[0025] Please see the appendix Figure 8 - Appendix Figure 9 In a preferred embodiment of the present invention, the wire pressing assembly 9 includes a movable base 91, which is slidably connected to the outer periphery of the second lead screw 8. The movable base 91 is used to install the upright plate 92, the second spring 910, and other wire pressing related components, providing stable installation support for each component of the wire pressing assembly 9. It can also slide along the second lead screw 8, driving the entire wire pressing assembly 9 to move left and right, adjusting the wire pressing position to adapt to the wire take-up requirements at different positions of the take-up shaft 4. An upright plate 92 is fixedly connected to the top of the movable base 91, and a fixed rod 93 is fixedly connected to the top of the upright plate 92. A deflection plate 94 is rotatably connected to the outer side of the fixed rod 93. The deflection plate 94 is used to install a pulley 95, and its deflection angle is adjusted to... The movable pulley 95 moves up and down, thereby adjusting the pressing pressure of the pulley 95 on the enameled wire. Simultaneously, the elastic force of the second spring 910 achieves elastic pressing of the enameled wire. A groove 96 is provided inside the deflection plate 94, and a pulley 95 is slidably connected inside the deflection plate 94. The pulley 95 is used to directly contact the enameled wire, elastically pressing it down. Its rolling characteristics convert the sliding friction with the enameled wire into rolling friction, minimizing wear on the insulation layer of the enameled wire surface, while ensuring a smooth pressing process and not affecting the normal transport of the enameled wire. A wing nut 97 is threaded inside the pulley 95, and the second spring 910 is fixedly connected to the outside of the movable seat 91. The second spring 910 provides elastic force to the wire pressing assembly 9. Through its own elastic deformation, it provides a continuous upward pulling force to the deflection plate 94, thereby causing the pulley 95 to exert a continuous and uniform elastic downward pressing force on the enameled wire. At the same time, when there is a momentary change in the tension of the enameled wire, the second spring 910 can adaptively adjust the pressure through extension and retraction to avoid excessive or insufficient pressure affecting the winding quality. A connecting block 99 is fixedly connected to the top of the second spring 910, and a support column 98 is fixedly connected to the outside of the deflection plate 94. The support column 98 is used to connect the deflection plate 94 and the connecting block 99, transferring the elastic force of the second spring 910 to the deflection plate 94, and providing a stable support point for the connecting block 99. To ensure the stability of the connection between the connecting block 99 and the support column 98, and to prevent the connection from loosening due to the tension of the second spring 910; the movable seat 91 is threaded to the outside of the second lead screw 8, and the fixed seat 6 is fixedly connected to the outside of the third motor 7, the output end of the third motor 7 is fixedly connected to one end of the second lead screw 8; the pulley 95 is slidably connected inside the slide groove 96, the outside of the wing nut 97 abuts against the outside of the deflection plate 94, and the support column 98 contacts the connecting block 99. The contact and cooperation between the two realizes the power transmission between the second spring 910 and the deflection plate 94, ensuring that the elastic force of the second spring 910 can be efficiently transmitted to the deflection plate 94, while reducing the wear of the connection and extending the service life of the equipment.

[0026] Working principle: When using this equipment, first turn on the take-up machine through the control box 12 on the base 1. Then, put the take-up shaft 4 on the outer circumference of the inner support assembly 5, and then turn the knob 59 to clamp the take-up shaft 4 to prevent loosening during take-up. Then, start the second motor 58 to drive the inner support assembly 5 and the take-up shaft 4 to rotate and wind up the enameled wire. At the same time, the rotation drives the unwinding shaft 11 rotating on the support frame 10 to unwind the wire. At the same time, start the third motor 7 on the fixed base 6 to drive the second lead screw 8 to rotate, which in turn causes the pressing assembly 9 to move left and right, so that the enameled wire is evenly wound on the take-up shaft 4. At the same time, when the unwinding speed of the unwinding shaft 11 is fast, it drives the enameled wire to be pressed synchronously to maintain its tension. When the enameled wire is finished winding, start the unloading assembly 3 to drive the take-up shaft 4 to move downward and slide to the left. When it moves to the bottom, release the clamp on the take-up shaft 4 and let the unloading assembly 3 move to the right to realize the automatic unloading function. When the take-up shaft 4 is fixed and clamped, the knob 59 is turned to drive the first lead screw 51 to rotate, so that the outer shell 52 slides along the outside of the rotating rod 53, thereby driving the multiple inner support plates 55 connected by the second rotating plate 56 to expand and move outward. At the same time, the second sliding block 57 at the bottom of the inner support plate 55 slides in the slot of the slotted plate 54, thereby clamping the inner side of the take-up shaft 4 with the inner support plate 55. When applying elastic pressure to the enameled wire, before winding up the wire, rotate the wing nut 97 according to the required tension level to loosen the bolt inside the pulley 95. Then, the wire slides inside the groove 96 on the deflection plate 94. When it slides to the appropriate position, tighten the wing nut 97 to lock the pulley 95. Then, guide the enameled wire around the two pulleys 95 to the winding shaft 4. Then, rotate the second lead screw 8 to move the moving seat 91 left and right to evenly wind up the enameled wire. When the winding speed is slow and the unwinding shaft 11 unwinds the wire too slowly, the tension will cause the deflection plate 94 to rotate outside the fixed rod 93 in the middle of the upright plate 92. At the same time, the connecting block 99 and the second spring 910 at the bottom of the support column 98 at its bottom will elastically press down to prevent the wire from breaking due to excessive winding. When the winding is completed and the material is unloaded, the first motor 33 on the placement plate 34 is started to rotate half a turn, driving the rotating shaft 35 to rotate, which in turn drives the gear 312 and the turntable 36 to rotate synchronously, which in turn drives the first sliding block 37 to rotate. The force of the rotation of the first sliding block 37 causes the first rotating plate 32 to deflect on the support plate 31, which in turn causes the slider 38 sliding on the other side of the first rotating plate 32 to slide downward inside the bracket 2 under the action of force. At the same time as sliding downward, the bracket 2 is connected by the first spring 310. The limiting ball 311 slides out of the limiting groove 39, releasing the anti-slip lock. Since the rack 313 meshes with the gear 312, when the gear 312 rotates, it drives the rack 313 and the top connecting plate 314 to slide outward, thereby pushing the bracket 2 to slide to the left along the slide rail 13. When it slides to the bottom, it releases the clamp on the take-up shaft 4, completing the unloading of the take-up shaft 4. Then the motor is started to reverse, driving the bracket 2 to slide to the right. At the same time, the slider 38 moves up to the top of the bracket 2 to perform the next cycle of take-up.
