Description

Technical Field

[0001] This application relates to the technical field of cable-making machine wrapping equipment, and in particular to a wrapping scrap rewinding device for cable-making machines. Background Technology

[0002] In cable manufacturing, the cabling machine is a key piece of equipment, undertaking the important process of twisting multiple conductors into cables. In order to improve the insulation performance, mechanical strength and protection capabilities of cables, the cables are usually wrapped. The wrapping process in the cabling machine refers to the process of tightly spirally winding strip materials (such as non-woven fabric, mica tape, aluminum-plastic composite tape, water-blocking tape, etc.) around the surface of the cable core or insulated core during the cable forming process. It is a key process in cable manufacturing and directly affects the mechanical strength, insulation performance, water-blocking / flame-retardant properties of the cable.

[0003] However, the wrapping process generates a large amount of scrap strip material. Taking the 1+4 / 1250 cable forming machine as an example, it generates a large amount of small-wound material during the wrapping production operation. Because the remaining amount is small, it is difficult to directly put it into subsequent production. The small-wound material that is not effectively processed accumulates in large quantities, occupies the company's storage space, causes material waste, and increases the company's production costs. At present, there is no special processing equipment for the small-wound material generated by the cable forming machine. Some companies use manual splicing to connect the small rolls into usable rolls.

[0004] However, the manual splicing method requires workers to carefully align the ends of the small rolls of material and then secure them with tape or other simple methods before rewinding the connected material. This process is not only time-consuming and labor-intensive, significantly extending the material processing cycle and reducing production efficiency, but also results in poor uniformity of the spliced ​​rolls due to the limitations of manual operation. Consequently, problems such as tape deviation and breakage can easily occur during subsequent use of the cable forming machine, affecting the production quality and progress of the cables.

[0037] In the existing structure of wrapping materials, the strip is usually wound on a core to form a strip roll structure. The core can be a hollow cylindrical structure, which is convenient to match the shaft structure of the wrapping equipment. In use, by fixing one end of the strip to the cable, the strip is continuously wound on the cable along the length of the cable by rotating the core.

[0038] Example 1

[0039] Please see Figures 1-5 A wrapping and rewinding device for a cable-making machine includes a worktable 100, a first winding mechanism 200, a second winding mechanism 300, a drive mechanism 400, and a tension adjustment mechanism 500. The first winding mechanism 200 is movably connected to the worktable 100 and can fix the wrapping material roll. The second winding mechanism 300 is movably connected to the worktable 100 and can fix the take-up of the wrapping material roll. The first winding mechanism 200 and the second winding mechanism 300 are spaced apart and can be connected by a strip drive. The drive mechanism 400 is connected to the second winding mechanism 300 to drive the second winding mechanism 300 to rotate around a first axis. The tension adjustment mechanism 500 is connected to the first winding mechanism 200 to adjust the tension of the first winding mechanism 200.

[0040] In this embodiment, as Figure 1 , Figure 2 As shown, the first winding mechanism 200 is movably connected to the worktable 100, allowing the first winding mechanism to rotate relative to the worktable 100. The remaining small rolls of scrap tape after the wrapping process can be fixed to the first winding mechanism 200 and rotate synchronously with it. The second winding mechanism 300 is also movably connected to the worktable 100. The first winding mechanism 200 is movably connected to the worktable 100 via a bearing seat, allowing it to rotate relative to the worktable 100 as well. The take-up tape roll is fixed to the second winding mechanism 300. The scrap strip roll 0 and the take-up strip roll fixed in the second winding mechanism 300 are located on the same plane, and there is a certain gap between the scrap strip roll and the take-up strip roll. That is, the first winding mechanism 200 and the second winding mechanism 300 are installed on the same end face of the worktable 100, and the first winding mechanism 200 and the second winding mechanism 300 are set at a certain distance apart. The drive mechanism 400 is connected to the second winding mechanism 300, and the drive mechanism 400 can drive the second winding mechanism 300 to rotate relative to the worktable 100 along the first axis. The tension adjustment mechanism 500 is connected to the first winding mechanism 200.

[0041] In practical work, a scrap strip roll is first fixed to the first winding mechanism 200, and the take-up strip roll is fixed to the second winding mechanism 300. Then, one end of the strip material on the scrap strip roll is manually wound around the take-up strip roll 3-5 times, so that the second winding mechanism 300 and the first winding mechanism 200 are connected by belt drive through the strip material. The drive mechanism 400 is started, and the drive mechanism 400 drives the second winding mechanism 300 to rotate around the first axis, so that the take-up strip roll can wind the strip material. As the strip material is wound, the first winding mechanism 200 is driven to rotate, thereby releasing the strip material from the scrap strip roll. During this winding process, the tension adjustment mechanism 500 is adjusted according to the slack of the strip material, thereby adjusting the tension of the first winding mechanism 200. Increasing the tension of the first winding mechanism 200 increases the resistance to rotation of the first winding mechanism 200, thereby preventing the strip material from slack. Decreasing the tension of the first winding mechanism 200 decreases the resistance to rotation of the first winding mechanism 200, making the strip material slack and reducing friction. The operator can adjust the tension of the first winding mechanism 200 by observing the running status of the strip. After the strip of the scrap material roll is wound to the take-up roll, the drive mechanism 400 is stopped, the scrap material roll is removed from the first winding mechanism 200, and another scrap material roll is replaced. One end of the scrap material roll is connected to the tail end of the strip on the take-up roll, and the drive mechanism 400 is restarted so that the take-up roll winds up the strip on the scrap material roll again. By following the above steps, the small rolls of strip from multiple scrap material rolls are wound into a large roll of wrapped strip, which is convenient for reuse.

[0042] In the above structure, by setting the first winding mechanism 200 and the second winding mechanism 300 to work together, multiple small rolls of scrap tape can be rewound to form a large roll of wrapped tape. This realizes the automatic rewinding function of small rolls of scrap tape, which greatly improves work efficiency, increases the utilization rate of small rolls of scrap tape, effectively avoids waste, and reduces production costs. In addition, by setting the tension adjustment mechanism 500 to be connected to the first winding mechanism 200 to adjust the tension of the first winding mechanism 200, the slack of the small rolls of scrap tape during the winding process can be adjusted, thereby reducing the error in the neatness of the rolled tape after winding, improving the continuity of subsequent production, improving the stability of the wrapping work, and ensuring the production quality and progress of the cable.

[0043] In the specific structure of the first winding mechanism 200, the first winding mechanism 200 includes a tape unloading reel 210 and a first rotating shaft 220. The tape unloading reel 210 is fixedly connected to the first rotating shaft 220, and the first rotating shaft 220 is movably connected to the worktable 100 and can rotate around its own axis. The tape unloading reel 210 can fix the scrap tape roll. The tape unloading reel 210 includes a first base plate 211 and a first cover plate 212 spaced apart along the axial direction of the first rotating shaft 220. The scrap tape roll is fixed between the first base plate 211 and the first cover plate 212, and the scrap tape roll is sleeved on the first rotating shaft 220 between the first base plate 211 and the first cover plate 212. The first cover plate 212 is detachably connected to the first rotating shaft 220. The first winding mechanism 200 also includes a first locking nut 230. The first rotating shaft 220 has a first threaded portion at one end near the first cover plate 212. The first locking nut 230 is engaged with the first threaded portion to fix the first cover plate 212 to the first rotating shaft 220.

[0044] In this embodiment, as Figure 4 As shown, the first rotating shaft 220 is fixedly connected to the tape feeding reel 210. The tape feeding reel 210 has a circular disc structure. The first rotating shaft 220 and the tape feeding reel 210 are coaxially arranged. The tape feeding reel 210 can be connected to the first rotating shaft 220 by a flat key. The first rotating shaft 220 can be movably connected to the worktable 100 by a bearing to facilitate the rotation of the first rotating shaft 220. The tape feeding reel 210 is installed on one end face of the worktable 100. In use, the core of the scrap tape roll is fixed on the tape feeding reel 210. The tape tray body 210 includes a first cover plate 212 and a first base plate 211. Both the first base plate 211 and the first cover plate 212 are circular plate structures, and the diameters of the first base plate 211 and the first cover plate 212 are the same. The first base plate 211 has a first mounting hole at its center. One end of the first rotating shaft 220 passes through the first mounting hole and extends a certain distance. The first rotating shaft 220 and the first base plate 211 can be connected by a flat key. The first cover plate 212 has a second mounting hole at its center, through which the first cover plate 212 can be connected to the first rotating shaft 220. The first cover plate 212 and the first base plate 211 are coaxially arranged, thereby making the first cover plate 212 and the first base plate 211... Plates 211 are arranged opposite each other, and there is a certain gap between the first cover plate 212 and the first base plate 211 to fix the corner strip roll. The first cover plate 212 is detachably connected to the first rotating shaft 220. In use, the first cover plate 212 is separated from the first rotating shaft 220, and the core of the corner strip roll is sleeved on the part of the first rotating shaft 220 located between the first base plate 211 and the first cover plate 212, so that the core is fixedly connected to the first rotating shaft 220, thereby allowing the corner strip roll to rotate with the first rotating shaft 220 to release the strip. Then, the first cover plate 212 is connected to the first rotating shaft 220 to clamp the corner strip roll between the first base plate 211 and the first cover plate 212.

[0045] By setting the first base plate 211 and the first cover plate 212 to clamp and fix the corner strip roll on the first rotating shaft 220, the axial movement of the corner strip roll on the first rotating shaft 220 is effectively restricted. At the same time, the first base plate 211 and the first cover plate 212 also provide a limiting function for the strip material of the corner strip roll, avoiding the problem of strip material deviation during the winding process, improving the stability of the winding work, and ensuring the neatness after winding.

[0046] In addition, the first winding mechanism 200 further includes a first locking nut 230 in the connection structure between the first cover plate 212 and the first rotating shaft 220. The first rotating shaft 220 has a first threaded portion at one end passing through the first mounting hole. After the scrap tape roll is fitted onto the first rotating shaft 220, the first cover plate 212 is connected to the first rotating shaft 220 through the second mounting hole. The first threaded portion passes through the first cover plate 212. Then, the first locking nut 230 is engaged with the first threaded portion until one end of the first locking nut 230 abuts against the first cover plate 212, thereby locking the first cover plate 212 onto the first rotating shaft 220. The threaded connection between the first locking nut 230 and the first rotating shaft 220 facilitates the installation and removal of the first cover plate 212 and improves the stability of the connection.

[0047] It should be noted that, in order to prevent the first base plate 211 and the first cover plate 212 from moving axially on the first rotating shaft 220, the first rotating shaft 220 is provided with a first limiting boss and a second limiting boss in sequence along the axial direction. The diameter of the first limiting boss is larger than the diameter of the first mounting hole, and the diameter of the second limiting boss is the same as the diameter of the first mounting hole and larger than the diameter of the second mounting hole. The core of the corner strip roll is also sleeved on the second limiting boss.

[0048] In the specific structure of the second winding mechanism 300, the second winding mechanism 300 includes a take-up reel 310 and a second rotating shaft 320. The take-up reel 310 is fixedly connected to the second rotating shaft 320, and the second rotating shaft 320 is movably connected to the worktable 100. The drive mechanism 400 is connected to the second rotating shaft 320 and is at least used to drive the second rotating shaft 320 to rotate around its own axis, so that the axis of the second rotating shaft 320 forms a first axis. The take-up reel 310 can fix the take-up tape roll. The take-up reel 310 includes a second base plate 311 and a second cover plate 312 spaced apart along the axial direction of the second rotating shaft 320. The take-up tape roll is fixed between the second base plate 311 and the second cover plate 312, and the take-up tape roll is sleeved on the second rotating shaft 320 between the second base plate 311 and the second cover plate 312. The second cover plate 312 is detachably connected to the second rotating shaft 320. The second winding mechanism 300 also includes a second locking nut 330. The second rotating shaft 320 is provided with a second threaded portion at one end near the second cover plate 312. The second locking nut 330 is engaged with the second threaded portion to fix the second cover plate 312 to the second rotating shaft 320.

[0049] In this embodiment, as Figure 5As shown, the structure of the second winding mechanism 300 is similar to that of the first winding mechanism 200. The second rotating shaft 320 is fixedly connected to the take-up reel 310. The take-up reel 310 has a circular disc structure. The second rotating shaft 320 and the take-up reel 310 are coaxially arranged. The take-up reel 310 can be connected to the second rotating shaft 320 by a flat key. The second rotating shaft 320 can be movably connected to the worktable 100 by a bearing to facilitate the rotation of the second rotating shaft 320. The take-up reel 310 is installed on one end face of the worktable 100. The take-up reel 310 includes a second cover plate 312 and a second base plate 311. Both the second base plate 311 and the second cover plate 312 are circular plate structures, and the diameters of the second base plate 311 and the second cover plate 312 are the same, but the diameter of the second base plate 311 is larger than the diameter of the first base plate 211, thus facilitating the limiting of the take-up tape roll. The second base plate 311 has a third mounting hole at its center, and the second cover plate 312 has a fourth mounting hole at its center. The second cover plate 312 and the second base plate 311 are coaxially arranged, and the second base plate 311 and the second cover plate 312 are connected to the second rotating shaft 320 through the third mounting hole and the fourth mounting hole, respectively. There is a certain gap between the second cover plate 312 and the second base plate 311 to fix the tape roll. The second cover plate 312 and the second rotating shaft 320 are detachably connected. In use, the second cover plate 312 and the second rotating shaft 320 are separated, and the core of the tape roll is sleeved on the part of the second rotating shaft 320 located between the second base plate 311 and the second cover plate 312, so that the core is fixedly connected to the second rotating shaft 320, thereby allowing the tape roll to rotate with the second rotating shaft 320 to wind up the tape. Then, the second cover plate 312 is connected to the second rotating shaft 320 to clamp the tape roll between the second base plate 311 and the second cover plate 312.

[0050] In addition, the second winding mechanism 300 also includes a second locking nut 330. After the winding tape is successfully mounted on the second rotating shaft 320, the second cover plate 312 is connected to the first rotating shaft 220 through the second mounting hole. Then, the second locking nut 330 is engaged with the second threaded part until one end of the second locking nut 330 abuts against the second cover plate 312, thereby locking the second cover plate 312 onto the second rotating shaft 320. The threaded connection between the second locking nut 330 and the second rotating shaft 320 facilitates the installation and removal of the second cover plate 312 and improves the stability of the connection.

[0051] By setting the second base plate 311 and the second cover plate 312 to clamp and fix the take-up tape roll on the second rotating shaft 320, the axial movement of the take-up tape roll on the second rotating shaft 320 is effectively restricted. At the same time, the second base plate 311 and the second cover plate 312 also provide a limiting function for the tape material of the take-up tape roll, ensuring the neatness after winding.

[0052] In addition, the first axis is the axis of the second rotating shaft 320. The drive mechanism 400 is connected to the second rotating shaft 320 to drive the second rotating shaft 320 to rotate around its own axis, thereby driving the take-up reel 310 and the take-up tape roll to rotate, so as to realize the take-up operation.

[0053] In the specific structure of the workbench 100, the workbench 100 is a vertical structure. The workbench 100 includes a support part 140 and a working part 130 connected to each other. The first winding mechanism 200 and the second winding mechanism 300 are both movably connected to the side end face of the working part 130.

[0054] In this embodiment, as Figure 1 As shown, the workbench 100 has a vertical structure and is a cuboid structure placed vertically. The workbench 100 includes a support part 140 located on the lower side and a working part 130 located on the upper side. The support part 140 can be a four-column structure, located at the four corners of the working part 130. The support part 140 is in contact with the ground or work platform to support the working part 130. One end face of the working part 130 forms a working surface. The first winding mechanism 200 and the second winding mechanism 300 are both movably connected to the working surface. The tape release reel 210 and the tape take-up reel 310 are installed on the outer side of the working surface. The first rotating shaft 220 and the second rotating shaft 320 pass through the working surface and enter the interior of the working part 130. The axis directions of the first rotating shaft 220 and the second rotating shaft 320 are arranged in the horizontal direction.

[0055] By designing the workbench 100 as a vertical structure, the floor space is reduced, making it suitable for production workshops with limited space. It also makes it easier for operators to stand in an ergonomic position when performing operations such as changing belts and adjusting tension, thus reducing labor intensity.

[0056] In the specific structure of the tension adjustment mechanism 500, the tension adjustment mechanism 500 includes a tension wheel 510, a tension belt 520, and an adjustment assembly 530. The tension wheel 510 is fixedly connected to the first rotating shaft 220. The tension belt 520 is wound around the tension wheel 510. One end of the tension belt 520 is fixed to the worktable 100, and the other end is connected to the adjustment assembly 530. The adjustment assembly 530 is used to adjust at least half of the tension force on the tension belt 520. In particular, the tension belt 520 is wound around at least half of the tension wheel 510. In addition, the tension wheel 510 is provided with a limiting groove 511 along its circumference to accommodate the tension belt 520.

[0057] In this embodiment, as Figure 2 , Figure 3As shown, the tension wheel 510 is fixed to one end of the first rotating shaft 220 relative to the tape reel 210 and is coaxially arranged with the first rotating shaft 220. One end of the tension belt 520 is fixed to the worktable 100, specifically to the inner wall of the working part 130. Then, the tension belt 520 is wound around the tension wheel 510, and the other end is connected to an adjustment component 530. The adjustment component 530 can adjust the tension of the tension belt 520, thereby increasing the contact friction between the tension belt 520 and the tension wheel 510, and thus adjusting the tension of the first rotating shaft 220 when it rotates. The tension belt 520 passes through at least half of the tension wheel 510, thereby increasing the contact area between the tension belt 520 and the tension wheel 510, thereby increasing the area of ​​force action between the tension belt 520 and the tension wheel 510, and improving the accuracy of tension adjustment. In order to prevent positional misalignment between the tension belt 520 and the tension wheel 510 during tension adjustment, a limiting groove 511 is provided along the circumference of the tension wheel 510. The width of the limiting groove 511 matches the width of the tension belt 520, and the depth of the limiting groove 511 is greater than the thickness of the tension belt 520. The tension belt 520 is wound around the limiting groove 511.

[0058] More specifically, the adjustment assembly 530 includes a connecting shaft 531, an adjusting nut 532, a first adjusting spring 533, and a second adjusting spring 535. The worktable 100 is connected to a bracket 110, which has a guide hole 111. One end of the connecting shaft 531 is provided with a fixing clamp 534, which is used to fix the tension band 520 at least. The connecting shaft 531 passes through the guide hole 111. The side of the connecting shaft 531 opposite to the fixing clamp 534 has an adjusting thread. The adjusting nut 532 is connected to the adjusting thread. The first adjusting spring 533 and the second adjusting spring 535 are both sleeved on the connecting shaft 531. One end of the first adjusting spring 533 is fixedly connected to one end face of the bracket 110, and the other end abuts against the adjusting nut 532. One end of the second adjusting spring 535 is fixedly connected to the fixing clamp 534, and the other end is fixedly connected to the other end face of the bracket 110.

[0059] In this embodiment, the connecting shaft 531 extends vertically, and a fixing clamp 534 is provided at the upper end of the connecting shaft 531. The fixing clamp 534 is used to fix the tension band 520. The fixing clamp 534 includes a first clamp plate and a second clamp plate connected at the bottom. The first clamp plate and the second clamp plate form a U-shaped groove, and one end of the tension band 520 is inserted into the U-shaped groove. The first clamp plate and the second clamp plate are respectively provided with a first opening and a second opening. The fixing bolt is passed through the first opening, through the tension band 520, and through the second opening in sequence, thereby fixing the tension band 520 on the fixing clamp 534. Additionally, a support 110 is mounted on the workbench 100. This support 110 has a guide hole 111 extending vertically through its body. One end (lower end) of the connecting shaft 531 relative to the fixed clamp 534 passes through the guide hole 111, dividing the shaft into two parts. One part is located on the upper side of the support 110 (the first part), and the other part is located on the lower side of the support 110 (the second part). The second part has an adjusting thread on its end, and an adjusting nut 532 is threaded into the adjusting thread. The first adjusting spring 533 is sleeved on the second part of the connecting shaft 531 and abuts against the bracket 110 and the adjusting nut 532. Specifically, the upper end of the first adjusting spring 533 is fixedly connected to the lower end face of the bracket 110, and its lower end abuts against the adjusting nut 532. The second adjusting spring 535 is sleeved on the first part of the connecting shaft 531 and abuts against the bracket 110 and the fixing clamp 534. Specifically, the upper end of the second adjusting spring 535 is fixedly connected to the lower end face of the fixing clamp 534, and its lower end is fixedly connected to the upper end face of the bracket 110.

[0060] During operation, the first adjusting spring 533 and the second adjusting spring 535 are pre-compressed by rotating the adjusting nut 532. Based on the characteristics of the strip to be rewinded, the pre-compression of the first adjusting spring 533 and the second adjusting spring 535 is adjusted to appropriate values, setting the initial tension. If insufficient strip tension is observed during equipment operation, the operator can rotate the adjusting nut 532 clockwise. The adjusting nut 532 moves axially downwards along the adjusting thread, causing the first adjusting spring 533 to extend. The connecting shaft 531 moves downwards, compressing the second adjusting spring 535. As the spring compression increases, the spring force increases, pulling the tension belt 520 through the connecting shaft 531. This increases the friction between the tension belt 520 and the tension wheel 510, thereby increasing the rotational resistance of the first winding mechanism 200, slowing down the unwinding speed of the scrap strip roll, and increasing the strip tension. At this time, the first adjusting spring 533 is in an elastically extended state, and its elastic reaction force keeps the connecting shaft 531 relatively stable. If the tension of the strip is found to be too high, the adjusting nut 532 can be rotated counterclockwise to move it upward along the adjusting thread, compressing the first adjusting spring 533, thereby causing the connecting shaft 532 to move upward, which in turn drives the second adjusting spring 535 to extend. The second adjusting spring 535 gradually extends under its own elastic force, the tension belt 520 relaxes, the friction force on the tension wheel 510 decreases, the rotational resistance of the first winding mechanism 200 decreases, the speed of winding and unwinding the scrap strip increases, and the tension of the strip decreases accordingly. At this time, the first adjusting spring 533 is in an elastic compression state, and its elastic reaction force keeps the connecting shaft 531 in a relatively stable state.

[0061] In the above structure, continuous and precise tension adjustment is achieved through the engagement of the adjusting nut 532 and the adjusting thread. By precisely controlling the number of rotations of the adjusting nut 532, the tension adjustment accuracy of the strip can be further improved. Furthermore, the engagement of the connecting shaft 531 and the guide hole 111 ensures the stability of the force direction on the tension band 520 during adjustment, avoiding tension fluctuations caused by force deviation. This adjusting assembly 530 uses a threaded adjustment method, allowing operators to master the adjustment method with simple training. The simple structure of each component significantly reduces equipment maintenance costs.

[0062] In the specific structure of the drive mechanism 400, the drive mechanism 400 includes a drive motor 410 and a transmission belt 420. The first pulley 430 is fixedly connected to one end of the second rotating shaft 320 relative to the take-up reel 310. The drive motor 410 is fixed on the worktable 100. The output end of the drive motor 410 is fixed with a second pulley 440. The first pulley 430 and the second pulley 440 are connected by transmission belt 420.

[0063] In this embodiment, as Figure 2As shown, the drive motor 410 is fixed to the support end of the worktable 100. Specifically, the support end is also provided with a crossbeam structure, which is fixed between the column structure. The drive motor 410 is fixed to the crossbeam structure. Installing the drive motor 410 on the support end can increase the counterweight at the bottom of the worktable 100 and improve the support stability of the worktable 100. A second pulley 440 is fixed at the output end of the drive motor 410. A first pulley 430 is fixed at one end of the second rotating shaft 320 relative to the take-up reel 310. The first pulley 430 and the second pulley 440 are connected by a transmission belt 420. When the drive motor 410 works, it drives the second pulley 440 to rotate, and then drives the first pulley 430 to rotate through the transmission belt 420, thereby driving the second rotating shaft 320 and the take-up reel 310 to rotate, realizing the take-up operation. By using a belt drive, transmission efficiency can be effectively improved. In addition, the relative positions of the second rotating shaft 320 and the drive motor 410 can be adjusted as needed to improve applicability and overload protection. When the equipment is overloaded due to reasons such as belt jamming, the transmission belt 420 will slip on the pulley, thereby cutting off power transmission, preventing the drive motor 410 from burning out due to overload, reducing damage to other components, improving the safety and reliability of the equipment, and extending the service life of the equipment.

[0064] In addition, the device also includes a guide roller mechanism 600, which is disposed on the worktable 100 and located between the first winding mechanism 200 and the second winding mechanism 300. The guide roller mechanism 600 includes at least two guide rollers 610, which are spaced apart and have different axial heights. The strip can pass around the two guide rollers 610 in sequence and in opposite directions.

[0065] In this embodiment, as Figure 1 , Figure 2As shown, a guide roller mechanism 600 is also installed on the working surface of the workbench 100 between the unloading reel 210 and the take-up reel 310. The guide roller mechanism 600 includes at least two guide rollers 610. The guide rollers 610, the unloading reel 210, and the take-up reel 310 are all located on the same plane. The two guide rollers 610 have different heights and are spaced apart. For example, in this embodiment, the guide roller 610 located on the lower side is positioned closer to the unloading reel 210, and the guide roller 610 located on the upper side is positioned closer to the unloading reel 210. The guide rollers are positioned close to the take-up reel 310. During the guiding process, one end of the scrap strip on the unloading reel 210 is wound around the lower guide roller 610 from bottom to top, and then wound around the higher guide roller 610 from top to bottom. Finally, the strip is wound onto the take-up reel 310. These two guide rollers 610 act as guides for the unloading and take-up of the strip. In addition, the two guide rollers 610 with different axial heights and opposite winding directions form an S-shaped transmission path for the strip, effectively dispersing the tension of the strip during transmission and preventing the strip from deviating or twisting due to uneven force, thus ensuring smooth transmission of the strip.

[0066] Specifically, the worktable 100 is provided with a first moving groove 120, and two guide rollers 610 are movably connected in the first moving groove 120, so that the guide rollers 610 can move along the first moving groove 120, and the first moving groove 120 is inclined.

[0067] In this embodiment, the workbench 100 has an inclined first moving groove 120 on its working surface. The first moving groove 120 is a rectangular groove structure. Guide rollers 610 are installed in the first moving groove 120. The two guide rollers 610 are installed at intervals. Since the first moving groove 120 is an inclined structure, there is a certain height difference between the two guide rollers 610. The guide rollers 610 are movably connected in the first moving groove 120 and can move along the first moving groove 120 to adjust the horizontal position and height of the guide rollers 610. Specifically, the guide roller 610 includes a roller body and a roller shaft. The roller body and the roller shaft can be connected by a bearing, so that the roller body can rotate relative to the roller shaft. The roller shaft passes through the first moving groove 120 and is fixed at a corresponding position in the first moving groove 120 by a fixing nut.

[0068] By setting an inclined first moving groove 120, the guide roller 610 can change its height and horizontal position simultaneously when moving, thereby achieving a composite adjustment of the strip tension. In addition, by adjusting the position of the guide roller 610 within the inclined first moving groove 120, it can flexibly adapt to the conveying needs of strips of different thicknesses and materials, thus improving the versatility of the equipment.

[0069] Example 2

[0070] Please see Figure 6 A wrapping scrap rewinding device for a cable-making machine is disclosed in Embodiment 2. The other structures are basically the same as those in Embodiment 1, with the following differences: The guide roller mechanism 600 includes a guide rail 620, which is movably connected to the worktable 100. The guide rail 620 has a second moving groove 621 extending along its length. A guide roller 610 is movably connected to the second moving groove 621, allowing the guide roller 610 to move along the second moving groove 621. The guide rail 620 can rotate relative to the worktable 100 around a second axis to adjust the position of the guide roller 610. A rotating shaft 630 is fixedly connected to the middle of the guide rail 620. The rotating shaft 630 is movably connected to the worktable 100, and its axis is the second axis. The rotating shaft 630 can be driven to rotate by external force, thereby driving the guide rail 620 to rotate.

[0071] In this embodiment, the guide rail 620 is a rectangular strip structure. A second moving groove 621 is provided on the end face of the guide rail 620. The second moving groove 621 is also a rectangular groove structure. The guide roller 610 can be movably connected in the second moving groove 621 and can move in the second moving groove 621 as needed, thereby adjusting the horizontal and vertical positions of the guide roller 610. The guide rail 620 is movably connected to the working surface of the worktable 100. The guide rail 620 can rotate relative to the worktable 100 around a second axis, thereby further adjusting the height and horizontal position of the guide roller 610.

[0072] In the above structure, the guide roller 610 can move linearly within the second moving groove 621, while the guide rail 620 can rotate around the second axis, realizing multi-angle and multi-position adjustment of the guide roller 610 in the plane. This structure can quickly adapt to strips of different specifications and different transmission path requirements, improving versatility. By adjusting the position of the guide roller 610 and the angle of the guide rail 620, the wrap angle and force direction between the strip and the guide roller 610 can be precisely changed, achieving fine control of the strip tension.

[0073] In the rotating structure of the guide rail 620, a rotating shaft 630 is fixed in the middle of the guide rail 620. The rotating shaft 630 is movably connected to the worktable 100, and the axis of the rotating shaft 630 is a second axis. The second axis is set in the horizontal direction. The axis of the rotating shaft 630 is perpendicular to the length direction of the guide rail 620. The rotating shaft 630 can be connected to the worktable 100 through bearings, thereby ensuring the smooth rotation of the rotating shaft 630 and the guide rail 620.
