Description

Technical Field

[0001] This invention relates to the field of take-up device technology, and more specifically to a continuously variable automatic reel-changing take-up machine for cable production lines. Background Technology

[0002] Cable production is a continuous industrial process. As the final key process, winding requires the continuous cable after extrusion, cooling, and traction to be neatly wound. It is necessary to ensure stable cable tension to avoid sheath stretching or structural damage, and to achieve efficient winding to match the continuous output of the front-end production line. Its level of automation directly determines the overall production efficiency and product qualification rate.

[0003] Reelless cable take-up machines, with their expandable and contractible drum structure (eliminating the need for traditional reels), achieve cable winding by opening the drum and cable unwinding by contracting it, simplifying reel-changing operations. They are gradually replacing traditional reel-based take-up machines in the large-scale production of medium and large-sized cables. Their core advantage lies in reducing reel storage and replacement costs, adapting to continuous production needs, but the continuity issue during reel-changing still needs to be addressed.

[0004] Existing reelless take-up machines still have significant shortcomings in the reel changing process: existing take-up machines all rely on manual reel changing and cannot automatically change reels, resulting in low operating efficiency; moreover, the incoming end of the cable production line is usually directly connected to equipment such as extruders, and these devices should not be frequently started and stopped once started. When the take-up machine needs to change the reel, if the winding is completely stopped, it will cause the cable to accumulate at the incoming end or be forced to stop, which will seriously affect the continuity and efficiency of production. Especially on high-speed production lines, frequent start-stop not only reduces capacity but also increases energy consumption and raw material waste. Summary of the Invention

[0005] The purpose of this invention is to provide a continuously variable automatic reel-changing take-up machine for cable production lines, so as to solve the problem that existing take-up machines require manual reel changing and need to stop the machine when changing reels.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A continuously variable transmission (CVT) automatic reel-changing and take-up machine for cable production lines includes a frame, an unloading assembly, and a take-up assembly mounted on top of the frame; it also includes: a mounting plate fixedly connected to the front of the frame; a wire clamping assembly mounted on the take-up assembly for securing the wire end during reel changing; a wire cutting assembly for cutting the cable during reel changing; a follow-up control assembly for adjusting according to cable tension; the follow-up control assembly includes a slide rail fixedly connected to one side of the mounting plate, the slide rail being vertically arranged, a slide table slidably connected to the slide rail, a counterweight fixedly connected to the top of the slide table, and an auxiliary guide wheel rotatably connected to one side of the slide table; an active control assembly for actively adjusting cable tension; a signal acquisition component including an infrared sensor mounted on top of the frame for continuously acquiring the height signal of the slide table; and a data comparison component for receiving the height signal acquired by the signal acquisition component, comparing the real-time acquired height signal with the height signal acquired at the previous acquisition time point and the height of the middle position of the slide rail, generating a tension control command based on the comparison result, and transmitting the generated tension control command to the active control assembly and the take-up assembly.

[0008] By adopting the above technical solution, the cooperation of the active control component and the follow-up control component can temporarily store the surplus cable continuously produced at the production end during the reel changing process, avoiding production interruption, realizing reel changing without stopping the machine, and significantly improving production efficiency. Preferably, the solution uses a gravity-driven follow-up control component to replace the traditional spring structure, which makes the tension adjustment more stable and effectively avoids cable damage caused by elasticity fluctuations. The setting of the signal acquisition and data comparison component can monitor the cable tension status in real time, accurately control the action of the active control component and the take-up component, ensure the stability of cable tension throughout the entire reel changing and take-up process, and ensure the quality of cable take-up.

[0009] A further improvement of the technical solution of the present invention is that: the active control component includes several support guide wheels rotatably connected to the mounting plate, the several support guide wheels are on the same horizontal straight line, a first linear module is fixedly installed on the side of the mounting plate near the support guide wheels, the first linear module can control its movable end to make linear movement, the movable end of the first linear module is fixedly connected to an adjustment seat, several control guide wheels are rotatably connected to the adjustment seat, and the control guide wheels are interspersed between each support guide wheel.

[0010] By adopting the above technical solution, a stable conveying path for the cable is provided by setting several supporting guide wheels on the same horizontal straight line. The design of the control guide wheels interspersed among the supporting guide wheels allows for flexible adjustment of the cable storage path length by changing the position of the control guide wheels, achieving precise storage and release of surplus cable. The first linear module drives the adjustment seat to move, and adjusts the cable storage state in a timely manner in accordance with the tension control command to ensure stable cable tension. Moreover, it can also avoid problems such as cable entanglement and friction during the storage process, ensuring the surface quality of the cable.

[0011] A further improvement of the technical solution of the present invention is that: the take-up assembly includes a gantry frame fixedly connected to the top of the frame, a fixed plate fixedly connected to one side of the gantry frame, a lifting cylinder fixedly connected to the top of the fixed plate, the piston rod of the lifting cylinder extending to the bottom of the fixed plate and fixedly connected to a lifting plate, a take-up motor fixedly connected to the lifting plate, the output shaft of the take-up motor fixedly connected to a cover plate, a core rod fixedly connected to the center of the bottom of the cover plate, a sleeve rod slidably sleeved on the outside of the core rod, a first spring fixedly connected between the inner end face of the sleeve rod and the end of the core rod, and a roll structure that can be opened and closed fixedly connected to the bottom of the sleeve rod; a turntable is rotatably connected to the top of the frame, and the central axis of the turntable is on the same straight line as the output shaft of the take-up motor.

[0012] By adopting the above technical solution, the lifting cylinder, lifting plate, core rod, sleeve rod and first spring can be used to lift the drum structure. The coordinated action of the turntable and the drum structure can complete the unwinding of the wire roll and the automatic clamping of the wire end without manual intervention, which greatly shortens the reel changing time and ensures the continuity of reel changing without stopping the machine. The winding motor drives the cover plate and the drum structure to rotate, ensuring that the cable is wound neatly. The overall structure has a high degree of automation, which effectively improves production efficiency and winding quality.

[0013] A further improvement of the technical solution of the present invention is that: the drum structure includes an end plate fixedly connected to the sleeve rod, a plurality of slide bars are slidably connected to the end plate, an arc plate is fixedly connected to one end of the slide bars, and a tension spring is fixedly connected between the inner side of the arc plate and the outer wall of the sleeve rod; a guide platform is fixedly connected to the bottom of the cover plate, the upper part of the guide platform is cylindrical and the lower part is frustum-shaped.

[0014] By adopting the above technical solution, the opening and closing of the drum structure is achieved by utilizing the elastic force of the tension spring and the mechanical squeezing action of the guide table. No additional power source is required, which simplifies the equipment structure and reduces manufacturing costs and failure probability. The structural action is smooth and reliable, and can quickly respond to the needs of reel changing and winding, ensuring the stable operation of the winding machine and improving the practicality and economy of the equipment.

[0015] A further improvement of the technical solution of the present invention is that: the clamping assembly includes a support plate fixedly connected to the top of the cover plate, a second linear module fixedly connected to one side of the support plate, a slide block fixedly connected to the movable end of the second linear module, a slide rod fixedly connected inside the slide block, a second spring sleeved on the outside of the slide rod, a movable block slidably connected to the outside of the slide rod, a movable column fixedly connected to one side of the movable block, and a movable clamp fixedly connected to the bottom of the movable column; a fixed column fixedly connected to the slide block, and a fixed clamp fixedly connected to the bottom of the fixed column; a U-shaped plate fixedly connected to the side of the support plate near the second linear module, a guide plate installed inside the U-shaped plate, and the movable column moves horizontally by pressing and engaging with the inclined surface on the guide plate.

[0016] By adopting the above technical solution, the precise movement of the movable clamp can be achieved through the inclined extrusion of the second linear module, the movable column and the guide plate. Combined with the buffering effect of the second spring, the clamping force is kept stable, which not only prevents the wire end from falling off, but also prevents damage to the cable. The wire clamping action and the reel changing process are highly coordinated, which can quickly complete the wire clamping operation, save time for wire cutting and wire end splicing, and ensure efficient reel changing without stopping the machine.

[0017] A further improvement of the technical solution of the present invention is that: the guide plate is slidably connected to the inside of the U-shaped plate, the U-shaped plate has a threaded hole, and an adjusting screw is threadedly connected to the U-shaped plate at the location of the threaded hole. One end of the adjusting screw has a knob, and the other end extends into the inside of the U-shaped plate and is rotatably connected to the guide plate.

[0018] By adopting the above technical solution, the extrusion stroke of the movable column can be flexibly adjusted by adjusting the screw to drive the guide plate, thereby changing the distance between the movable clamp and the fixed clamp. This allows for the adaptation to cables of different diameters without the need to replace the clamping components, improving the equipment's versatility and production flexibility, reducing specification changeover time, and increasing production efficiency.

[0019] A further improvement of the technical solution of the present invention is that the length of the fixed clamp is greater than that of the movable clamp.

[0020] By adopting the above technical solution, the wire clamping process can be carried out continuously while the cover plate rotates slowly, with smooth operation. There is no need to stop the rotation of the wire take-up component, which greatly shortens the wire clamping time, avoids cable accumulation or tension loss due to wire clamping delay, ensures the wire storage balance of the active control component, and further improves the efficiency and stability of non-stop reel changing.

[0021] A further improvement of the technical solution of the present invention is that a rubber friction layer is provided on the top of the turntable and the bottom of the end plate to increase the friction between the turntable and the end plate.

[0022] By adopting the above technical solution, the relative sliding between the end and the turntable during the winding process can be avoided, thus preventing wear on the cable.

[0023] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0024] 1. This invention, through the cooperation of an active control component and a follow-up control component, can temporarily store surplus cable continuously produced at the production end during reel changing, avoiding production interruptions, achieving reel changing without stopping the machine, and significantly improving production efficiency; the solution uses a gravity-driven follow-up control component to replace the traditional spring structure, resulting in smoother tension adjustment and effectively avoiding cable damage caused by elasticity fluctuations; the setting of signal acquisition and data comparison components can monitor the cable tension status in real time, accurately control the actions of the active control component and the take-up component, ensure stable cable tension throughout the entire reel changing and take-up process, and guarantee cable take-up quality.

[0025] 2. This invention enables fully automated reel changing without human intervention. The wire clamping assembly, wire cutting assembly, unloading assembly, and wire take-up assembly work together to automatically complete a series of reel changing operations, such as wire end fixing, cable cutting, wire reel transfer, and new wire end connection. No manual assistance is required for wiring or unloading, which greatly reduces the intensity of manual operation and avoids errors that may be caused by manual operation, thereby further improving the overall processing efficiency.

[0026] 3. This invention provides a stable cable transport path by setting several supporting guide wheels on the same horizontal straight line. The design of the control guide wheels interspersed among the supporting guide wheels allows for flexible adjustment of the cable storage path length by changing the position of the control guide wheels, thus achieving precise storage and release of surplus cable. The first linear module drives the adjustment seat to move, and adjusts the cable storage state in a timely manner in accordance with the tension control command to ensure stable cable tension.

[0027] 4. This invention features a liftable drum structure with a linkage mechanism that allows it to automatically open or close during lifting, thus achieving automatic unwinding. Furthermore, the coordinated action of the turntable and drum structure enables the unwinding of the cable roll and automatic clamping of the cable ends, eliminating the need for manual intervention. This significantly reduces reel-changing time and ensures continuous reel-changing without downtime. The winding motor drives the cover plate and drum structure to rotate, ensuring neat cable winding. The overall structure boasts a high degree of automation, effectively improving production efficiency and winding quality.

[0028] 5. By setting two clamps of different lengths, the present invention allows the wire clamping process to continue continuously while the cover plate rotates slowly, with smooth operation. It does not require stopping the rotation of the take-up assembly, which greatly shortens the wire clamping time, avoids cable accumulation or tension loss due to wire clamping delay, ensures the wire storage balance of the active control assembly, and further improves the efficiency and stability of non-stop reel changing.

[0042] The present invention will be further described in detail below with reference to the embodiments.

[0043] Example 1

[0044] like Figures 1-11As shown, this invention provides a continuously variable automatic reel-changing take-up machine for cable production lines, including a frame 1, an unloading assembly, and a take-up assembly 5 mounted on the top of the frame 1; it also includes: a mounting plate 2, fixedly connected to the front of the frame 1; a wire clamping assembly 7, disposed on the take-up assembly 5, used to fix the wire end during reel changing; a wire cutting assembly 9, used to cut the cable during reel changing; and a follow-up control assembly 3, used to make adjustments according to the cable tension; the follow-up control assembly 3 includes a slide rail 301 fixedly connected to one side of the mounting plate 2, the slide rail 301 is vertically arranged, a slide table 302 is slidably connected to the slide rail 301, a counterweight 303 is fixedly connected to the top of the slide table 302, and an auxiliary [unclear - possibly a component or device] is rotatably connected to one side of the slide table 302. Guide roller 304; active control component 4, used to actively adjust cable tension; signal acquisition component, including infrared sensor 10 installed on the top of frame 1, used to continuously acquire the height signal of slide table 302; data comparison component, used to receive the height signal acquired by the signal acquisition component, compare the real-time acquired height signal with the height signal acquired at the previous acquisition time point and the height of the middle position of slide rail 301, generate tension control command based on the comparison result, and transmit the generated tension control command to active control component 4 and take-up component 5. While controlling the tension through active control component 4, control the take-up speed of take-up component 5 (take-up motor 505 speed), thereby coordinating the surplus cable in the system.

[0045] By coordinating the active control component 4 and the follow-up control component 3, surplus cable continuously produced at the production end can be temporarily stored during reel changing, avoiding production interruptions and achieving reel changing without stopping the machine, significantly improving production efficiency. Preferably, the solution utilizes a gravity-driven follow-up control component 3 instead of a traditional spring structure, resulting in smoother tension adjustment and effectively preventing cable damage caused by elasticity fluctuations. The signal acquisition and data comparison components can monitor the cable tension status in real time, precisely controlling the actions of the active control component 4 and the take-up component 5 to ensure stable cable tension throughout the reel changing and take-up process, guaranteeing cable take-up quality. Furthermore, the entire process requires no manual intervention, achieving automatic reel changing and improving processing efficiency.

[0046] During cable production, the cable first passes around the auxiliary guide wheel 304 of the follow-up control component 3 and then enters the take-up component 5 for winding. In the follow-up control component 3, the slide table 302 is kept balanced by the gravity of the counterweight 303, and the auxiliary guide wheel 304 provides stable support for the cable. When the cable tension changes, the slide table 302 will slide up and down along the vertically set slide rail 301.

[0047] During reel changing, the cable end is first secured by the clamping assembly 7, the cable is cut by the cutting assembly 9, and the take-up assembly 5 rises to prepare for rewiring. The unloading assembly includes a third linear module 11 and an electric clamp 12 installed at the movable end of the third linear module 11. The electric clamp 12 of the unloading assembly clamps the wound cable, and then the third linear module 11 conveys it to the packaging machine to complete the film wrapping. During the above process, the production end continuously produces cables, resulting in excess cable in the system. This excess cable cannot provide sufficient support for the auxiliary guide wheel 304. Under the gravity of the counterweight 303, the slide table 302 slides downward, and the auxiliary guide wheel 304 moves downward accordingly to balance the tension. A sensing element is installed at the bottom of the slide table 302 to work with the light source of the infrared sensor 10. The infrared sensor 10 collects the height signal of the slide table 302 at regular intervals. After receiving the signal, the data comparison component compares the real-time signal with the signal at the previous moment and the height of the middle position of the slide rail 301. If the height at the next moment is lower than that at the previous moment and lower than the middle of the slide rail 301, it indicates that the cable is slack. The data comparison component sends a cable storage command to the active control component 4. The first linear module 401 drives the adjustment seat 402 to move, so that the control guide wheel 403 passes between the support guide wheel 404 to form a longer cable storage path, storing excess cable and tensioning the cable. If the height at the next moment is higher than that at the previous moment, it indicates that the cable take-up speed of the take-up component 5 is greater than the production speed. The data comparison component sends a cable release command, and the active control component 4 resets and releases the stored cable.

[0048] When changing reels, the take-up assembly 5 first winds up the cable stored in the active control assembly 4 at a speed higher than normal, until the cable stored in the active control assembly 4 is completely released and the slide table 302 is reset. Then the take-up speed gradually decreases to the normal speed that matches the production end, and enters a stable take-up state.

[0049] The cutting assembly 9 can be an electric cutter, a pneumatic cutter, a hydraulic cutter, or other structures capable of automatically controlling the cutting action, such as... Figure 11 As shown, this is an optional wire cutting scheme in this embodiment. The scheme provides an existing pneumatic cutter, including a plate, a first cutter head fixedly connected to one end of the plate, a control plate hinged to the plate, a second cutter head fixedly connected to one end of the control plate, and a cutting cylinder hinged to the plate. The piston rod of the cutting cylinder is hinged to the control plate.

[0050] Example 2

[0051] like Figure 2 and Figure 3As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the active control component 4 includes a plurality of support guide wheels 404 rotatably connected to the mounting plate 2, the plurality of support guide wheels 404 being on the same horizontal straight line, a first linear module 401 being fixedly installed on the side of the mounting plate 2 near the support guide wheels 404, the first linear module 401 being controllable to make linear motion at its movable end, an adjustment seat 402 being fixedly connected to the movable end of the first linear module 401, a plurality of control guide wheels 403 being rotatably connected to the adjustment seat 402, the control guide wheels 403 being interspersed among the support guide wheels 404.

[0052] The above scheme proposes the functional requirements of the active control component 4, but does not specify the specific structure. Existing conventional wire storage devices mostly adopt a single guide wheel group structure, which has low accuracy in adjusting the wire storage length. In addition, the cables are prone to problems such as messy wiring and mutual friction during the wire storage process, which affects the surface quality of the cables. At the same time, they cannot respond quickly to tension control commands, making it difficult to meet the precise wire storage requirements when changing reels without stopping the machine.

[0053] By setting several support guide rollers 404 on the same horizontal straight line, a stable conveying path is provided for the cable. The design of the control guide rollers 403 interspersed among the support guide rollers 404 allows for flexible adjustment of the cable storage path length by changing the position of the control guide rollers 403, enabling precise storage and release of surplus cable. The first linear module 401 drives the adjustment seat 402 to move, and adjusts the cable storage state in a timely manner in accordance with the tension control command to ensure stable cable tension. Moreover, it can also avoid problems such as cable entanglement and friction during the storage process, ensuring the surface quality of the cable.

[0054] Reference Figure 2 and Figure 3 During operation, the cable sequentially passes around each support guide wheel 404 to form a horizontal transport path. When the data comparison component issues a cable storage command, the first linear module 401 is activated, and its movable end drives the adjusting seat 402 to move vertically. The regulating guide wheel 403 on the adjusting seat 402 moves accordingly. Since the regulating guide wheel 403 is inserted between the support guide wheels 404, its movement will cause the cable to form more bending paths, thereby increasing the cable storage length, realizing the storage of surplus cable and tensioning the cable. When it is necessary to release the stored cable, the first linear module 401 drives the adjusting seat 402 to move in the opposite direction, the regulating guide wheel 403 resets, the cable storage path shortens, and the stored cable is gradually released until the active regulating component 4 returns to its initial state, completing the cycle of cable storage and release.

[0055] Example 3

[0056] like Figure 4 , Figure 5 and Figure 6As shown, based on Embodiment 2, the present invention provides a technical solution: Preferably, the take-up assembly 5 includes a gantry frame 501 fixedly connected to the top of the frame 1, a fixed plate 502 fixedly connected to one side of the gantry frame 501, a lifting cylinder 503 fixedly connected to the top of the fixed plate 502, the piston rod of the lifting cylinder 503 extending to the bottom of the fixed plate 502 and fixedly connected to a lifting plate 504, a take-up motor 505 fixedly connected to the lifting plate 504, a cover plate 506 fixedly connected to the output shaft of the take-up motor 505, a core rod 507 fixedly connected to the center of the bottom of the cover plate 506, a sleeve rod 508 slidably sleeved on the outside of the core rod 507, a first spring 509 fixedly connected between the inner end face of the sleeve rod 508 and the end of the core rod 507, and a roll structure 6 that can be opened and closed fixedly connected to the bottom of the sleeve rod 508; a turntable 13 is rotatably connected to the top of the frame 1, and the central axis of the turntable 13 is on the same straight line as the output shaft of the take-up motor 505.

[0057] In existing reelless take-up machines, the connection between the cut cable end and the take-up assembly 5 during reel changing requires manual assistance. This is not only time-consuming and labor-intensive, but also easily leads to the cable end not being securely fixed, affecting the subsequent winding quality. At the same time, manual connection will prolong the reel changing time and reduce the efficiency of reel changing without stopping the machine, which cannot meet the needs of automated production.

[0058] The lifting cylinder 503, lifting plate 504, core rod 507, sleeve rod 508, and first spring 509 work together to achieve lifting and buffering of the drum structure 6. The coordinated action of the turntable 13 and the drum structure 6 can complete the unwinding of the wire roll and the automatic docking of the wire end without manual intervention, greatly shortening the reel changing time and ensuring the continuity of reel changing without stopping the machine. The winding motor 505 drives the cover plate 506 and the drum structure 6 to rotate, ensuring that the cable is wound neatly. The overall structure has a high degree of automation, effectively improving production efficiency and winding quality.

[0059] During normal winding, the lifting cylinder 503 drives the lifting plate 504 to descend, causing the drum structure 6 to fit against the turntable 13. The winding motor 505 starts, driving the cover plate 506, core rod 507, sleeve rod 508, and drum structure 6 to rotate synchronously, and the cable is neatly wound on the drum structure 6. When changing reels, the wire clamping assembly 7 clamps the cable end, and the wire cutting assembly 9 cuts the part between the cable and the reel. Then, the lifting cylinder 503 drives the lifting plate 504 to rise, and the drum structure 6 moves upward accordingly. Due to the loss of bottom support, the sleeve rod 508 extends relative to the core rod 507 under the action of the first spring 509, increasing the distance between the drum structure 6 and the cover plate 506, and no longer clamping the cable. During the process, the drum structure 6 is controlled to close, making the diameter smaller, and the reel detaches from the drum structure 6. The electric clamp 12 of the unloading assembly clamps the detached reel and conveys it to the baling machine. Simultaneously, the cut cable segment, along with the detached coil, is pulled towards the center of the cover plate 506; the control lifting cylinder 503 drives the lifting plate 504 to descend again, and the drum structure 6 moves down until it is pressed against the turntable 13. The turntable 13 generates an upward reaction force on the drum structure 6, causing the sleeve rod 508 to move upward relative to the core rod 507. The first spring 509 is compressed, and the top of the drum structure 6 and the bottom of the cover plate 506 press against each other, firmly clamping the cable end. Then the winding motor 505 starts again, beginning a new round of cable winding.

[0060] like Figure 6 , Figure 8 and Figure 9 As shown, preferably, the roll structure 6 includes an end plate 604 fixedly connected to the sleeve rod 508, a plurality of slide bars 605 slidably connected to the end plate 604, an arc plate 602 fixedly connected to one end of the slide bar 605, and a tension spring 603 fixedly connected between the inner side of the arc plate 602 and the outer wall of the sleeve rod 508; a guide platform 601 is fixedly connected to the bottom of the cover plate 506, the upper part of the guide platform 601 is cylindrical and the lower part is frustum-shaped.

[0061] Existing drum structures 6 mostly use motors or lifting cylinders 503 to drive opening and closing, requiring additional power sources and transmission mechanisms. This not only increases the complexity and manufacturing cost of the equipment but also makes it prone to power failures (especially since the above solutions are implemented on a high-speed rotating cover plate 506), affecting the stable operation of the equipment and failing to meet the efficient and reliable reel changing requirements of reelless take-up machines. Therefore, it is necessary to design a drum structure 6 that does not require additional power drive, simplifying the equipment and improving stability.

[0062] The opening and closing of the drum structure 6 is achieved by utilizing the elastic force of the tension spring 603 and the mechanical squeezing action of the guide table 601. No additional power source is required, which simplifies the equipment structure and reduces manufacturing costs and failure probability. The structure operates smoothly and reliably, and can quickly respond to the needs of reel changing and winding, ensuring the stable operation of the winding machine and improving the practicality and economy of the equipment.

[0063] During winding, the drum structure 6 moves downward and is pressed against the turntable 13. The reaction force of the turntable 13 causes the drum structure 6 to move upward. The lower part of the guide table 601 is shaped like a frustum, which exerts an outward pressing force on the arc plate 602. The arc plate 602 drives the slide bar 605 to slide outward along the end plate 604. The tension spring 603 is stretched, and the arc plates 602 move away from each other. The drum structure 6 opens, forming a stable winding diameter, which facilitates cable winding. During reel changing, the drum structure 6 moves upward and is released from the pressure of the turntable 13. The elasticity of the tension spring 603 is restored, pulling the arc plate 602 towards the sleeve rod 508. The slide bar 605 slides inward along the end plate 604. The arc plates 602 move closer to each other, and the drum structure 6 closes, reducing the diameter and facilitating the unwinding of the coil. It should be noted that when the drum structure 6 moves downward relative to the cover plate 506, it corresponds to the unwinding action of the cable reel. This process will release the cable clamping state between the drum structure 6 and the cover plate 506; conversely, when the drum structure 6 moves upward, it will clamp a new cable.

[0064] Example 4

[0065] like Figure 6 , Figure 7 and Figure 10 As shown, based on Embodiment 3, the present invention provides a technical solution: Preferably, the wire clamping assembly 7 includes a support plate 711 fixedly connected to the top of the cover plate 506, a second linear module 701 fixedly connected to one side of the support plate 711, a slide block 702 fixedly connected to the movable end of the second linear module 701, a slide rod 703 fixedly connected inside the slide block 702, a second spring 707 sleeved on the outside of the slide rod 703, and a movable block 704 slidably connected to the outside of the slide rod 703. A movable column 705 is fixedly connected to one side of the 04, and a movable clamp 706 is fixedly connected to the bottom of the movable column 705; a fixed column 708 is fixedly connected to the slide block 702, and a fixed clamp 709 is fixedly connected to the bottom of the fixed column 708; a U-shaped plate 710 is fixedly connected to the side of the support plate 711 near the second linear module 701, and a guide plate 801 is installed inside the U-shaped plate 710. The movable column 705 moves horizontally by pressing and engaging with the inclined surface on the guide plate 801.

[0066] The inclined pressing action of the second linear module 701, the movable column 705, and the guide plate 801 enables precise movement of the movable clamp 706. Combined with the buffering effect of the second spring 707, the clamping force is kept stable, preventing wire ends from falling off and cable damage. The wire clamping action is highly coordinated with the reel changing process, enabling the wire clamping operation to be completed quickly, saving time for wire cutting and wire end splicing, and ensuring efficient reel changing without stopping the machine.

[0067] When cable clamping is required, the second linear module 701 is activated, driving the slide 702 to move downwards. The slide 702 drives the movable column 705 and the fixed column 708 to move downwards simultaneously. During the downward movement, the movable column 705 contacts the inclined surface on the guide plate 801 and generates compression. Under the guidance of the inclined surface, the movable column 705 drives the movable block 704 to slide along the slide rod 703 towards the fixed column 708. The second spring 707 is compressed, and the movable clamp 706 moves with the movable block 704, gradually approaching the fixed clamp 709, and finally firmly clamping the cable between them. After the cable reel is removed and the new cable segment is clamped by the aforementioned reel structure 6, the second linear module 701 is controlled to drive the slide 702 to move upwards. The movable column 705 is released from the compression of the guide plate 801, the elasticity of the second spring 707 is restored, pushing the movable block 704 and the movable clamp 706 to reset, releasing the cable, and the second linear module 701 continues to move upwards until it is fully reset.

[0068] like Figure 6 and Figure 10 As shown, preferably, the guide plate 801 is slidably connected to the inside of the U-shaped plate 710. The U-shaped plate 710 has a threaded hole, and an adjusting screw 802 is threadedly connected to the U-shaped plate 710 at the location of the threaded hole. One end of the adjusting screw 802 has a knob 803, and the other end extends into the inside of the U-shaped plate 710 and is rotatably connected to the guide plate 801.

[0069] Based on the fixed clamp spacing of the clamping assembly 7, it can only be used for cables of a single diameter. When producing cables of different diameters, the clamping assembly 7 needs to be replaced, which is cumbersome, time-consuming and labor-intensive, reducing the versatility and production flexibility of the equipment and failing to meet the production needs of multiple types of cables.

[0070] By adjusting the screw 802 to drive the guide plate 801 to move, the extrusion stroke of the movable column 705 can be flexibly adjusted, thereby changing the distance between the movable clamp 706 and the fixed clamp 709. This allows for the adaptation of cables of different diameters without the need to replace the clamping assembly 7, improving the equipment's versatility and production flexibility, reducing specification changeover time, and increasing production efficiency.

[0071] When it is necessary to adapt to cables of different diameters, rotate the knob 803 of the adjusting screw 802. Since the adjusting screw 802 is threadedly connected to the U-shaped plate, the rotation of the knob 803 causes the adjusting screw 802 to move axially along the threaded hole. One end of the adjusting screw 802 pushes the guide plate 801 to slide horizontally inside the U-shaped plate, changing the position of the guide plate 801. After the position of the guide plate 801 is adjusted, the contact point between the movable column 705 and the inclined surface of the guide plate 801 changes when the movable column 705 moves down, and the pressing stroke changes accordingly. This adjusts the maximum clamping distance between the movable clamp 706 and the fixed clamp 709 to adapt to the diameter of the currently produced cable.

[0072] like Figure 7 As shown, preferably, the length of the fixed chuck 709 is greater than that of the movable chuck 706.

[0073] Since the clamping action of the clamping component 7 and the rotation action of the take-up component 5 are independent of each other, it is usually necessary to stop the rotation of the take-up component 5 before clamping the wire, which leads to a longer clamping time. However, the wire storage capacity of the active control component 4 is limited during the non-stop reel change process. Excessive clamping time will cause cable accumulation or tension loss, affecting the reel change efficiency.

[0074] The wire clamping process can continue while the cover plate 506 rotates slowly, with smooth operation. There is no need to stop the rotation of the wire take-up component 5, which greatly shortens the wire clamping time, avoids cable accumulation or tension loss due to wire clamping delay, ensures the wire storage balance of the active control component 4, and further improves the efficiency and stability of non-stop reel changing.

[0075] During reel changing, the take-up motor 505 drives the cover plate 506 to rotate slowly, while simultaneously controlling the second linear module 701 to drive the slide 702 to continue descending until the long fixed clamp 709 intervenes at the height of the cable (originally located above and not affecting cable winding, the cable will bypass the fixed clamp 709 after descent). During the rotation of the fixed clamp 709, the cable is lifted and pulled (at this stage, it is not yet clamped, but if the two clamps are of the same length, the cable will be blocked outside the two clamps and cannot enter the position between them). As the slide 702 continues to descend, the movable column 705 is pressed against the inclined surface of the guide plate 801, causing the movable clamp 706 to gradually move closer to the fixed clamp 709. This means that during the rotation of the cover plate 506, the movable clamp 706 and the fixed clamp 709 gradually approach and finally clamp the cable end. The entire clamping action is completed synchronously with the rotation of the cover plate 506, without any additional pause.

[0076] Preferably, a rubber friction layer is provided on the top of the turntable 13 and the bottom of the end plate 604 to increase the friction between the turntable 13 and the end plate 604.

[0077] To prevent wear on the cable caused by relative sliding between the end plate 604 and the turntable 13 during the winding process.

[0078] The first linear module 401 and the second linear module 701 have the same structure, and both include a mounting base (fixed end), a linear motor, a screw and a slider (movable end). The motor output shaft is fixedly connected to the screw, the slider is threadedly connected to the screw, and the slider is slidably connected to the screw mounting base.

[0079] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
