Description

Technical Field

[0001] This invention belongs to the technical field of cable winding equipment, specifically a tension adaptive adjustment device for a winding machine. Background Technology

[0002] In the entire steel wire production process, the take-up machine undertakes the key tasks of neatly winding, coiling, and centrally storing the steel wire. It is an indispensable core supporting equipment in the production line. Whether the tension can be kept stable during the winding stage will directly affect the final appearance and mechanical quality of the steel wire. In the actual steel wire winding operation, the take-up reel continuously winds the steel wire, and the diameter of the coil on the outside of the reel will gradually increase. If the equipment drive motor maintains a fixed speed, the actual winding speed of the steel wire will continue to increase as the coil diameter increases. The dynamic change of the winding speed will directly pull the steel wire, causing frequent fluctuations in winding tension. This can easily lead to uneven steel wire tension and messy winding, which seriously affects the winding and forming effect and the product qualification rate.

[0003] CN224015078U discloses a wire take-up tension adaptive adjustment device, comprising: an adjustment machine, a guiding mechanism, and a mounting base. The adjustment machine is installed outside the mounting base, and the guiding mechanism is disposed outside the mounting base. The guiding mechanism includes a U-shaped frame, an arc-shaped clamp for limiting the position of the wire, and a guide arc plate for guiding the direction of wire movement. The guide arc plate is disposed at one end of the arc-shaped clamp, and the arc-shaped clamp and the guide arc plate are integral structures and are mirror images of each other. By setting the guiding mechanism, this utility model can not only guide the direction of wire movement during the take-up process and limit the movement path of the wire to prevent the wire from flying out of the equipment due to excessive tension or path deviation, thus avoiding safety accidents, but also change the gap of the wire channel by adjusting the guiding mechanism, thereby meeting the take-up requirements of wires of different specifications and improving the practicality of the equipment.

[0004] In the aforementioned technologies, although the gap of the wire channel can be changed by adjusting the guide mechanism to meet the needs of wire winding of different specifications, the tension adjustment of traditional wire winding machines mostly adopts fixed counterweight, manual adjustment of spring preload or single electronic speed control. The manual adjustment method has serious lag and cannot adapt to the real-time tension fluctuations caused by the dynamic changes in the winding diameter during the winding process. It is very easy to cause problems such as wires being too loose and stacked, winding misalignment, or excessive tension leading to wire stretching deformation, wire breakage, and surface scratches. Summary of the Invention

[0005] To address the issues raised in the background art, such as the inability to adapt to real-time tension fluctuations caused by dynamic changes in the winding diameter during the winding process, which easily lead to loosely stacked steel wires, misaligned windings, or excessive tension causing steel wire stretching deformation, wire breakage, and surface scratches, this invention provides a tension adaptive adjustment device for a winding machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tension adaptive adjustment device for a take-up machine, comprising an adjustment component mounted on a frame, a take-up device mounted on the frame next to the adjustment component, and a control component mounted between the take-up device and the frame; The winding device includes a groove formed on the frame, a lead screw rotatably connected in the groove, a first servo motor fixedly connected to the top of the frame, and the output end of the first servo motor fixedly connected to the lead screw, a slide seat sleeved on the lead screw, a winding reel fixedly connected to the end of the slide seat away from the lead screw, a rotating shaft rotatably connected to the bottom of the winding reel, a turntable sleeved on the top of the rotating shaft, a plurality of winding rods fixedly connected in a ring at equal intervals at the bottom of the turntable, and a second servo motor fixedly connected to the top of the winding reel, with the output shaft of the second servo motor fixedly connected to the rotating shaft.

[0019] The technical solutions of 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.

[0020] like Figures 1 to 6 As shown, the present invention provides a tension adaptive adjustment device for a take-up machine, including an adjustment component 3 installed on a frame 1, a take-up device 2 installed on the side of the adjustment component 3 on the frame 1, and a control component 5 installed between the take-up device 2 and the frame 1. The winding device 2 includes a groove 201 formed on the frame 1. A lead screw 202 is rotatably connected in the groove 201. A first servo motor 203 is fixedly connected to the top of the frame 1, and the output end of the first servo motor 203 is fixedly connected to the lead screw 202. A slide 206 is sleeved on the lead screw 202. A winding reel 204 is fixedly connected to the end of the slide 206 away from the lead screw 202. A rotating shaft 209 is rotatably connected to the bottom of the winding reel 204. A turntable 207 is sleeved on the top of the rotating shaft 209. A plurality of winding rods 208 are fixedly connected in a ring at equal intervals at the bottom of the turntable 207. A second servo motor 205 is fixedly connected to the top of the winding reel 204, and the output shaft of the second servo motor 205 is fixedly connected to the rotating shaft 209. Adjustment component 3 includes a telescopic rod 301 rotating on frame 1, the movable section of which is fitted with a sleeve shaft 302. The side wall of the sleeve shaft 302 is provided with multiple sliding grooves 303 at equal intervals. A pair of clamping plates 305 are slidably connected in the sliding grooves 303. A first compression spring 304 is fixedly connected between the two clamping plates 305 located in the sliding grooves 303. The control component 5 includes a pressure sensor 501 fixed on the frame 1, and the pressure sensor 501 is located below the lead screw 202. A guide rail 502 located directly above the pressure sensor 501 is fixedly connected to the frame 1. A slide rod 503 is damped and slidably connected to the guide rail 502. A pressure rod 504 is fixedly connected to one end of the slide rod 503 near the frame 1, and the pressure rod 504 is connected to the output end of the pressure sensor 501.

[0021] The pressure sensor 501 is electrically connected to the electromagnetic block 306 via a wire. The electromagnetic block 306 and the movable section of the telescopic rod 301 are magnetically repelled. The bottom end of the winding reel 204 is provided with an annular groove. The top end of the turntable 207 is fixedly connected with an annular block that matches the annular groove, and the annular block and the annular groove are engaged.

[0022] The above scheme is adopted: During the steel wire winding operation, the steel wire first passes through two sets of opposing clamping plates 305 inside the adjusting component 3. The first compression spring 304 continuously applies clamping force to the clamping plates 305, so that the clamping plates 305 are tightly attached to the outer wall of the steel wire, providing a constant basic clamping tension for the steel wire winding and preventing the steel wire from loosening and deviating. After the winding operation starts, the first servo motor 203 drives the lead screw 202 to rotate, which drives the slide 206 carrying the winding reel 204 to move up and down along the guide rail 502, thereby adjusting the vertical height of the winding reel 204 to adapt to the winding of the steel wire layer by layer. The path ensures that the steel wire is evenly and neatly wound on the surface of the take-up reel 204, preventing the steel wire from piling up or pressing. The end of the slide rod 503 of the control component 5 always maintains close contact with the outer surface of the steel wire. In the initial stage of winding, the diameter of the steel wire is small, and the slide rod 503 only slightly touches the steel wire, so the pressure value collected by the pressure sensor 501 is low. As winding continues, the diameter of the steel wire wound on the take-up reel 204 continuously increases, and the steel wire pushes the slide rod 503 outward. The slide rod 503 moves backward and continuously squeezes the pressure sensor 501. The pressure sensor 501 transmits the real-time pressure signal to the whole machine control system. The control system determines the increase in the steel wire coil diameter based on the pressure value and synchronously adjusts the output of the electromagnetic block 306 to generate a magnetic repulsive force. The electromagnetic block 306 and the movable section of the telescopic rod 301 generate a repulsive thrust, pushing the movable section of the telescopic rod 301 to extend outward. Simultaneously, it causes the two clamping plates 305 to shift slightly outward, increasing the clamping distance between the two sets of clamping plates 305 to accommodate the continuously increasing steel wire coil diameter and prevent the clamping plates 305 from squeezing and wearing down the outer steel wire. When the steel wire coil diameter decreases and the squeezing force of the slide rod 503 on the pressure sensor 501 decreases, the magnetic repulsive force of the electromagnetic block 306 weakens synchronously, and the first compression spring... 304 pulls the clamping plate 305 to reset and tighten, re-adhere to the surface of the steel wire, and stabilize the clamping tension. Relying on the slide rod 503, pressure sensor 501, electromagnetic block 306, telescopic rod 301 and clamping plate 305 to form a closed-loop linkage structure, the above technology realizes real-time adaptive tension adjustment based on the dynamic change of the coil diameter during the winding process. No manual intervention is required, which effectively avoids the problems of excessively loose stacking of steel wires and misaligned winding caused by the lag of traditional manual adjustment, or excessive tension causing steel wire stretching deformation, wire breakage and surface scratches. It effectively improves the finished product quality and winding regularity of the steel wire after winding.

[0023] like Figure 6 As shown, an auxiliary component 4 is installed on the side of the frame 1 away from the control component 5. The auxiliary component 4 includes a slide rail 401 fixed on the frame 1. A pair of sliders 402 are slidably connected inside the slide rail 401. A clamping rod 403 is fixedly connected to the end of the slider 402 away from the slide rail 401. A second compression spring 404 is fixedly connected between the upper and lower walls of the slide rail 401 and the corresponding sliders 402. A steel wire is threaded between the two clamping rods 403, and the winding section of the steel wire is attached to the surface of the sleeve shaft 302 between the two clamping plates 305 and wound around the surface of multiple winding rods 208.

[0024] The above solution is adopted so that when the wire exits slightly due to changes in the coil diameter during the winding process, the clamp 305 linked to the wire will also shift accordingly. To cope with this change, the upper and lower clamps 403 can adaptively adjust themselves in real time along the slide rail 401 of the auxiliary component 4 to follow the shift in the wire exit position under the synergistic action of the second compression spring 404 and the slider 402, and always maintain stable clamping and effective limiting of the exit section of the wire. This design effectively prevents the wire from shaking or misaligning during winding due to the shift in the exit position. This, in conjunction with the tension adjustment mechanism, maintains the overall stability of the winding operation and ensures the orderly winding process. In addition, the clamps 403 also have the function of scraping off excess grease from the surface of the wire, avoiding excessive oil residue on the surface of the wound wire, which would have an adverse effect on the quality of the final product.

[0025] like Figure 3 As shown, the frame 1 has multiple slots 210 located directly below the take-up bar 208 and the multiple take-up bars 208. The slots 210 engage with the corresponding take-up bars 208 and the shaft 209. The inner wall of the slots 210 is fixedly connected with anti-slip pads, and the anti-slip pads are fitted onto the surfaces of the corresponding take-up bars 208 and the shaft 209.

[0026] By adopting the above solution, the slot 210 can facilitate the user to unload the wound wire reel after winding. The user does not need to disassemble the entire transmission structure. They only need to pull the winding rod 208 and the rotating shaft 209 out of the slot 210 to complete the unloading. This effectively simplifies the unloading process and improves work efficiency. At the same time, the anti-slip pad added to the inner wall of the slot 210 can increase the friction between the winding rod 208, the rotating shaft 209 and the inner wall of the slot 210, and prevent unnecessary movement of the winding rod 208 or the rotating shaft 209 during the winding operation, ensuring the stability of the winding operation and improving the winding quality.

[0027] like Figures 1 to 3 As shown, the guide rail 502 is a damped sliding guide rail 502 structure, the slide rod 503 is matched and sleeved on the outside of the guide rail 502, and the inner side of the slide block 206 is fitted with a wear-resistant threaded sleeve, which is threadedly matched and engaged with the lead screw 202.

[0028] The above solution provides stable damping support for the sliding of the slide bar 503, preventing excessive shaking of the pressure roller due to wire tension fluctuations, ensuring the smoothness of the tension adjustment process, and enabling the pressure roller to stably adhere to the wire surface, maintaining the consistency of tension during winding. The wear-resistant threaded sleeve embedded inside the slide block 206 reduces thread wear during the movement of the slide block 206 caused by the rotation of the lead screw 202, extending the overall service life of the device. Even after long-term use, the accuracy of the slide block 206 position adjustment can still be guaranteed, avoiding errors in tension adjustment due to thread wear, and ensuring the long-term stability and winding accuracy of the device.

[0029] Working principle and usage process of this invention: First, the end of the steel wire to be wound is passed through the gap between the two clamping rollers 403 in sequence, and then smoothly inserted between the two sets of clamping plates 305 in the adjusting assembly 3. Finally, the end of the steel wire is firmly fixed on the winding rod 208 of the winding reel 204. During this process, the first compression spring 304 continuously pushes the clamping plate 305 to clamp the steel wire, providing the initial basic tension. At the same time, the second compression spring 404 pushes the two clamping rollers 403 to clamp the steel wire together, thereby completing all the preparations before winding and ensuring that the steel wire is in a stable tension state at the beginning stage. After the device is started, the second servo motor 205 starts working, driving the rotating shaft 209 and the turntable 207 to rotate synchronously, thereby driving multiple winding rods 208 to rotate together, officially entering the steel wire winding operation stage. At the same time, the first servo motor 203 drives the lead screw 202 to rotate, driving the slide 206 and the winding reel 204 to reciprocate in the vertical direction, so as to adapt to the spiral upward path when the steel wire is wound layer by layer, ensuring that the steel wire can be evenly and neatly arranged on the winding rods 208 during the winding process; As the winding operation continues, the diameter of the coiled steel wire increases, gradually pushing the slide bar 503, which is attached to the surface of the steel wire, outward. After being pushed, the slide bar 503 slides smoothly backward along the guide rail 502 and begins to squeeze the pressure sensor 501. After the pressure sensor 501 collects the signal of increased pressure, it quickly transmits the signal to the control system. The control system then increases the output power of the electromagnetic block 306, enhances the magnetic repulsion force generated by the electromagnetic block 306, thereby pushing the movable section of the telescopic rod 301 to extend outward, causing the sleeve shaft 302 and the clamping plate 305 to shift outward as a whole, increasing the clamping distance between the two clamping plates 305. This adapts to the change in the diameter of the coiled steel wire and avoids squeezing damage to the steel wire due to excessive tension. When the change in wire diameter becomes gradual or slightly decreases, the pressure of the slide bar 503 on the pressure sensor 501 decreases accordingly. The control system synchronously reduces the magnetic repulsive force of the electromagnetic block 306 based on the pressure change. At this time, the first compression spring 304 rebounds, pulling the clamping plate 305 inward to tighten and re-adhere to the surface of the wire, thereby maintaining a stable clamping tension on the wire and realizing adaptive dynamic adjustment of tension throughout the winding process. During the winding process, if the position of the steel wire exits is deviated, the clamping roller 403 will adjust synchronously and adaptively according to the position of the steel wire exit under the elastic force of the second compression spring 404 and the guidance of the slider 402, so as to always maintain the stable limit of the steel wire. At the same time, the clamping roller 403 can also effectively scrape off excess grease on the surface of the steel wire during the contact process, playing a role in cleaning and assisting in lubrication management. Once a set of take-up rods 208 completes the take-up task of the current steel wire, the second servo motor 205 immediately starts, driving the turntable 207 to rotate precisely, thereby quickly and accurately switching the next set of idle take-up rods 208 to the predetermined position for take-up of the steel wire. This process achieves a fast and smooth take-up operation, significantly improving the continuity of operations and overall production efficiency. After all take-up operations are completed, the operator only needs to easily pull the take-up rods 208 with the already wound steel wire directly out of the corresponding slots 210 to quickly complete the unloading operation and prepare for the next round of take-up operations.
