Description

Technical Field

[0001] The present application relates to the technical field of cable stranding machines, and in particular to a high-speed stranding machine for copper cable production. Background Art

[0002] Copper cable is a cable with high-purity copper as its core conductor. Thanks to copper's excellent conductivity and ductility, it can achieve efficient and stable transmission of electrical energy or signals. It is used in power transmission, building wiring, communication networks and internal connections of various electrical equipment. It is an indispensable basic material in modern industry and daily life.

[0003] Copper cable production uses high-purity electrolytic copper rods as raw material. These are first drawn into copper wire of a specific diameter using a wire drawing machine, then coated with insulating material through an extruder to form a single core. High-speed stranding machines are then used to twist multiple insulated cores at high speed, controlling the twist pitch and tension to ensure structural stability. The process then proceeds, including cable filling, armor wrapping, and outer sheath extrusion. Stranding machines are primarily categorized by structure and purpose into cage-type, tubular, and bundle stranding machines. Tubular stranding machines typically consist of a tube cage and a reel rack rotatably connected to the cage. The reel rack is equipped with reels, on which single strands of wire are wound.

[0004] Referring to the Chinese patent document with publication number CN119763935B, entitled "A Tubular Stranding Machine," the invention comprises a tube cage, a reel frame, a reel, and a drive assembly. The reel frame is provided with a counterweight mechanism comprising a mounting shaft, a connecting plate, and a counterweight assembly. The connecting plate is fixedly connected to a sliding rod at its end. The counterweight assembly comprises a slide plate, a connecting rod hinged to the end of the sliding rod, a support rod fixedly connected to the connecting rod and located on one side of the reel, a counterweight sleeve sleeved between two support rods located on the same side of the reel and capable of contacting the edge of the reel, and a spring connected between the two support rods. The slide plate is perpendicular to the connecting plate and has an inclined slot on the slide plate through which the slide rod passes. The document installs the reel between two mounting shafts, making it easy to assemble and disassemble. The reel and the mounting shaft fall under their own weight. Furthermore, the counterweight mechanism can shift the center of gravity of the reel downward, which helps reduce the swing of the reel frame and improves the uniformity of the reel payout.

[0005] While lowering the center of gravity of the wire reels helps reduce the swing amplitude of the wire reel frame, the reel frame's pivoting installation within the pipe cage and the potential for a shifted center of gravity after installation can cause the reel frame to tilt within the cage. This tilt adversely affects the payout process. While the reel frame can be leveled using a leveling assembly, the constant shifting direction of the tension acting on the wire and the fact that the wire is unwound from different positions on the reels during payout still make it difficult to avoid swinging, ultimately impacting the uniformity and stability of payout. Summary of the Invention

[0006] In view of this, the present application provides a high-speed stranding machine for copper cable production, which is mainly used to solve the problem that the pay-off frame is prone to swinging when the high-speed stranding machine for copper cable production is used, affecting the uniformity and stability of the pay-off.

[0007] In order to solve the above technical problems, the present application provides a high-speed stranding machine for copper cable production, comprising a base frame, a motor and a tube cage rotatably arranged on the base frame, the interior of the tube cage is rotatably connected to a wire drum rack, a wire drum is installed inside the wire drum rack, a leveling assembly is provided on one side of the wire drum rack, for keeping the wire drum rack in a horizontal state when stationary; a rotating shaft is provided on both sides of the wire drum rack, a set of equipment is rotatably sleeved on the rotating shaft on one side, a counterweight is provided at the bottom of the set of equipment, for keeping the set of equipment in a balanced posture when the tube cage rotates, and a support frame is provided on the top of the set of equipment; the leveling assembly includes A cross bar and a screw rotatably connected to the wire drum rack are arranged on the wire drum rack, a connecting plate is threadedly connected to the screw, the top of the connecting plate is slidably connected to the cross bar, and a leveling block is arranged at the bottom thereof, and one end of the screw passes through the wire drum rack and is fixedly connected to the turntable; a fixing frame is provided on one side of the wire drum rack, and an observation box is rotatably connected to the middle part of the fixing frame, and a flowable liquid is injected into the interior of the fixing frame; a linkage is provided on the support frame, and when the wire drum rack tilts, the linkage can rotate the observation box in the opposite direction of the tilt of the wire drum rack, and use the gravity of the liquid to generate a reset torque to realize dynamic leveling of the wire drum rack.

[0008] By employing this technical solution, after the wire reel is mounted on the reel frame, the center of gravity of the reel frame is adjusted using a leveling assembly, effectively reducing payout tension fluctuations caused by reel frame tilt and preventing dynamic amplification of the reel frame's swing amplitude due to centrifugal force during operation. The assembly maintains static stability thanks to the inertial balance of the counterweight, ensuring that the support frame provides excellent support for the linkage. If the reel frame tilts laterally during payout, the linkage rotates the observation box in the opposite direction of the reel frame's tilt. Gravity forces the liquid inside the observation box to flow toward the lower side, generating a restoring torque through the shifted mass of the liquid, causing the reel frame to automatically return to a horizontal position. This suppresses reel frame swing, improves payout uniformity and stability, and ensures smooth and continuous wire release. If the reel frame is initially tilted, the turntable rotates according to the direction of the tilt. This, in turn, drives the screw, causing the connecting plate to move along the screw axis. This, in turn, drives the leveling block, restoring the reel frame to a horizontal position.

[0009] Optionally, a lifting rod is movably installed on one side of the support frame, an arc-shaped pressure plate adapted to the rotating shaft is provided at the bottom of the lifting rod, a top plate is provided at the top of the lifting rod, an electromagnet is provided at the top of the support frame, a guide block is provided on one side of the bottom of the lifting rod, a first spring is provided on the top of the guide block, a limit frame for limiting the movement of the linkage part is movably installed at the bottom of the support frame, and a second spring is provided between the limit frame and the support frame.

[0010] By adopting this technical solution, the electromagnet generates magnetic force when energized, causing the top plate to attract the electromagnet under this magnetic force, causing the guide block to move laterally and squeeze one side of the limit frame. The limit frame then locks the linkage, restricting its rotation. At the same time, the curved pressure plate moves downward under the action of the lifting rod and presses the rotating shaft. The combined action of the limit frame and the curved pressure plate secures the reel frame, effectively preventing it from swinging left or right. This not only makes the installation of the reel more labor-saving and efficient, facilitating the work of the staff, but also significantly improves the overall efficiency of the reel changing operation.

[0011] Optionally, a rubber pad is provided at the bottom of the arc-shaped pressure plate, and a striped protrusion is provided circumferentially on the rotating shaft on one side of the kit.

[0012] By adopting the above technical solution, when the arc pressure plate and the rotating shaft come into contact, the elastic deformation of the rubber pad and the circumferentially arranged striped protrusions form an interlocking structure. By increasing the roughness of the contact surface, the friction between the arc pressure plate and the rotating shaft is improved, making the kit more securely fixed, thereby improving the stability of the limit frame during use.

[0013] Optionally, mounting grooves are provided on both sides of the wire reel rack, a clamping slot is provided on the side of the mounting groove close to the wire reel, a sleeve and an insertion rod are inserted into the inside of the wire reel, a third spring is provided inside the end of the sleeve close to the insertion rod, and the end of the insertion rod close to the third spring is inserted into the sleeve, a pressure block and a clamping block are provided on the sleeve and the insertion rod, and a connecting rod is provided on the end of the sleeve and the insertion rod away from the wire reel, the end of the connecting rod is fixedly connected to the side plate, and the clamping slot is adapted to the clamping block.

[0014] By adopting the above technical solution, when installing the cable reel, first insert one end of the sleeve into the circular hole inside the cable reel frame, then push the insertion rod axially into the sleeve, and then simultaneously squeeze the sleeve and the side plate at the end of the insertion rod, causing the third spring to compress and deform. At this time, the pressure blocks on both sides of the cable reel frame move toward the center and clamp the cable reel. Finally, the clamping blocks are aligned and inserted into the corresponding slots, allowing the connecting rod to enter the installation slot. Under the action of the restoring force of the third spring, the entire structure is locked into a stable state, thus completing the installation of the cable reel inside the cable reel frame.

[0015] Optionally, the outer peripheral surface of the pressing block is a conical working surface.

[0016] By adopting the above technical solution, after the pressing block contacts the wire drum, the wire drum and the pressing block can be placed in a coaxial state, thereby reducing eccentricity error; and the solution can be applied to wire drums of different sizes.

[0017] Optionally, the liquid level inside the observation box is 50%±10% of the box body height.

[0018] By adopting the above technical solution, the interior of the observation box has sufficient liquid mass to generate a reset force, while leaving space for the liquid to flow freely.

[0019] Optionally, the linkage part includes a movable part, a shift rod and a fixed rod. The movable part is rotatably connected to the middle part of the support frame, and the shift rod is arranged in the middle part of the bottom surface of the observation box; the fixed rod is arranged on the side of the online disk rack close to the fixed frame, and the fixed rod and the shift rod are movably sleeved on both sides of the movable part.

[0020] Optionally, one end of the limiting frame close to the guide block is rotatably connected to a roller.

[0021] By adopting the above technical solution, rollers are used instead of sliding contact surfaces, changing the friction between the limit frame and the guide block from sliding friction to rolling friction. This improvement reduces the movement resistance of the guide block, making it run more smoothly during operation.

[0022] Optionally, a reference line is provided on the side of the observation box.

[0023] By adopting the above technical solution, after the wire reel is installed, the operator can use the preset reference line as a benchmark to intuitively determine the liquid level status in the observation box, thereby achieving precise adjustment of the horizontality of the wire reel rack.

[0024] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0025] 1. By setting up a leveling structure, the reel rack with the installed wire reels can be adjusted to a horizontal state before the equipment is put into operation. This prevents the swing amplitude of the reel rack from being dynamically amplified during operation, and ensures that the reel rack maintains a good initial state. During operation, the equipment relies on the dynamic migration characteristics of the liquid in the balance box to sense and respond to the posture changes of the wire reel rack. The reverse compensation torque generated by gravity effectively suppresses the swing, achieving dynamic correction and stable control of the operating posture. Compared with traditional stranding machines, it can ensure that the wire reel always maintains a uniform and stable payout state during high-speed payout, ensuring that the wire can be released smoothly and continuously, which is conducive to improving the production quality of copper cables.

[0026] 2. Through the coordinated cooperation of the leveling structure and the locking assembly, the cable reel frame can be relatively fixed inside the pipe cage when installing the cable reel, effectively preventing it from swinging left and right. This not only makes the installation operation of the cable reel more labor-saving and efficient, facilitating the work of the staff, but also improves the overall work efficiency of the reel changing operation.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application Figure 1-Figure 7 , the technical solutions of the embodiments of the present application are clearly and completely described. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0036] Reference Figure 1 and Figure 2, this embodiment provides a high-speed stranding machine for copper cable production, including a machine body, a wire drum mounting part, a wire drum 4 and a leveling mechanism. The machine body includes a base frame 1, a motor 11 and a tube cage 2. The base frame 1 is used to carry the motor 11 and the tube cage 2. The tube cage 2 is rotatably set on the base frame 1, and its end is connected to the output end of the motor 11 through a belt transmission mechanism. The motor 11 is fixedly mounted on one end of the base frame 1; there are multiple wire drum mounting parts, and multiple wire drum mounting parts are movably mounted inside the tube cage 2 along the axial direction thereof; the leveling mechanism is arranged on the wire drum mounting part, and the number and position of the leveling mechanism are matched with the number and position of the wire drum mounting parts. In actual use, the configuration quantity of the wire drum mounting parts can be flexibly adjusted according to the actual needs of the cable harness. In addition, the belt transmission mechanism is a transmission structure commonly used in this field and will not be described here.

[0037] Among them, reference Figure 2 and Figure 5 The wire drum mounting member includes a wire drum frame 3 and a rotating shaft 31. There are two rotating shafts 31, which are rotatably connected to the two ends of the wire drum frame 3 through bearings, and the rotating shafts 31 are fixedly installed inside the tube cage 2.

[0038] When the pipe cage 2 rotates at high speed around the base frame 1 under the drive of the motor 11 through the belt transmission mechanism, the rotating shaft 31 fixedly installed inside the pipe cage 2 will rotate synchronously. During the installation of the wire drum 4, it can be steadily lifted above the wire drum frame 3 with the help of a crane or lifting equipment, and then slowly lowered to the installation area inside the wire drum frame 3. This lifting method avoids the heavy work of manual handling and can reduce the labor intensity of workers. After installation, the wire drum 4 can rotate freely around its own axis relative to the wire drum frame 3. When the stranding machine is running, the single strand of cable can be evenly released from the wire drum 4, providing a stable supply of wire for the subsequent stranding process.

[0039] Among them, reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The leveling mechanism includes a static leveling component and a dynamic leveling component. The static leveling component includes a crossbar 32 provided on the reel frame 3 and a screw 322 rotatably connected to the reel frame 3. A connecting plate 321 is threadedly connected to the screw 322. A sliding groove is provided at the bottom of the crossbar 32 along the axial direction. The top of the connecting plate 321 is slidably connected to the sliding groove at the bottom of the crossbar 32. A leveling block 323 is provided at the bottom of the connecting plate 321. One end of the screw 322 passes through the reel frame 3 and is fixedly connected to the turntable 324.

[0040] The dynamic leveling assembly includes a fixed frame 33, an observation box 331, a kit 35, a counterweight 351, a support frame 352, and a linkage. The rotating shafts 31 at both ends of the reel frame 3 are of different lengths, with one rotating shaft 31 being longer than the other. The kit 35 is rotatably mounted on the longer rotating shaft 31. The fixed frame 33 is fixedly connected to the top of the kit 35, and the counterweight 351 is fixedly connected to the bottom of the kit 35. The weight of the counterweight 351 is used to generate a stabilizing torque. According to the gravity pendulum effect, the counterweight 351 is always kept in a vertical direction by gravity, thereby offsetting the centrifugal force interference caused by the rotation of the rotating shaft 31 and preventing the kit 35 from rotating with the rotating shaft 31. Rotation; the fixed frame 33 is fixedly set on the side of the wire reel rack 3 near the sleeve 35, and the middle part of the observation box 331 is rotatably connected to the fixed frame 33 via a bearing; the observation box 331 is partially filled with liquid, and the liquid can flow freely in the chamber but is not completely filled; the observation box 331 is made of a transparent material, which is convenient for staff to observe the liquid level height inside it; the linkage can rotate the observation box 331 in the opposite direction of the tilt of the wire reel rack 3, using the gravity of the liquid to generate a reset torque to achieve dynamic leveling of the wire reel rack 3. The linkage includes a movable part 353, a lever 333 and a fixed rod 34. The middle part of the movable part 353 is rotatably connected to the support frame 352 via a bearing, and the lever 333 is fixedly connected to the middle part of the bottom surface of the observation box 331; the fixed rod 34 is fixedly connected to the side of the wire reel rack 3 near the fixed frame 33. The movable part 353 is provided with two symmetrically distributed strip holes. The fixed rod 34 and the lever 333 are movably mounted on both sides of the movable part 353 through the strip holes.

[0041] When the cam 321 is in the upright position, the lever 324 is in the upright position, and the lever 325 is in the upright position, so that the cam 321 is in the upright position, and the lever 326 is in the upright position, so that the cam 326 is in the upright position, and the lever 327 is in the upright position, so that the cam 327 is in the upright position, and the lever 328 is in the upright position, so that the cam 328 is in the upright position, and the lever 328 is in the upright position, so that the cam 326 is in the upright position, and the lever 326 is in the upright position, so that the cam 326 is in the upright position,

[0042] In addition, refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6, a lifting rod 5 is movably inserted on one side of the support frame 352, so that the lifting rod 5 can move up and down along the support frame 352, and an extension sleeve is provided on the support frame 352, and the lifting rod 5 movable sleeve is arranged inside the extension sleeve, by increasing the contact area between the lifting rod 5 and the support frame 352, the stability of the lifting rod 5 is improved; the bottom of the lifting rod 5 is provided with an arc-shaped pressure plate 51 adapted to the rotating shaft 31, and the top of the lifting rod 5 is provided with a top plate 57, and the top of the support frame 352 is provided with an electromagnet 56. The top plate 57 is made of metal. After the electromagnet 56 is energized, the top plate 57 can be adsorbed with the electromagnet 56 under the action of magnetic force; a guide block 52 is provided on one side of the bottom of the lifting rod 5, which guides The side of the block 52 close to the support frame 352 is inclined from top to bottom toward the side away from the limit frame 53, and a first spring 54 is provided on the top of the guide block 52, and the bottom of the first spring 54 is fixedly connected to the guide block 52, and the top of the first spring 54 is fixedly connected to the support frame 352. The bottom of the support frame 352 is movably inserted with a limit frame 53 for limiting the movement of the linkage part, and the side of the limit frame 53 close to the movable part 353 is provided with an opening, which is adapted to the movable part 353; a second spring 55 is provided between the limit frame 53 and the support frame 352, one end of the second spring 55 is fixedly connected to the limit frame 53, and the other end of the second spring 55 is fixedly connected to the support frame 352.

[0043] When the cable drum 4 is installed, the electromagnet 56 is energized to generate a magnetic force, causing the top plate 57 to move downward under the magnetic attraction and adhere to the electromagnet 56. During this process, the first spring 54 is stretched, and the top plate 57, via the lifting rod 5, simultaneously drives the guide block 52 downward. As the guide block 52 moves downward, the stop frame 53 moves laterally toward the support frame 352, compressing the second spring 55. Once the stop frame 53 is in place, it engages the outer side of the movable member 353, restricting its rotation.

[0044] At the same time, the lifting rod 5 drives the curved pressure plate 51 downward, pressing it firmly against the rotating shaft 31. This increases the friction between the rotating shaft 31 and the sleeve 35, thereby securing the sleeve 35. Because the movable member 353 is blocked by the stop frame 53 and cannot rotate, the position of the fixing rod 34 is also fixed, thus stably fixing the wire reel frame 3 and effectively preventing it from swinging side to side. This design not only makes the installation of the wire reel 4 easier and more efficient, reducing the workload of the staff, but also helps improve the overall efficiency of the reel changing operation.

[0045] Reference Figure 3 、 Figure 4 and Figure 5 A rubber pad 511 is provided at the bottom of the arc-shaped pressure plate 51, and a striped protrusion 311 is provided on the circumference of the rotating shaft 31 located on one side of the kit 35. The striped protrusion 311 is parallel to the axial direction of the rotating shaft 31, which can further increase the friction between the arc-shaped pressure plate 51 and the rotating shaft 31.

[0046] The cooperation between the rubber pad 511 and the striped protrusion 311 can increase the friction between the arc-shaped pressure plate 51 and the rotating shaft 31, making the fixation of the kit 35 more secure, thereby improving the stability of the limit frame 53 during use.

[0047] Reference Figure 2 、 Figure 5 and Figure 7 The wire drum frame 3 has mounting slots 36 on both sides. A clamping slot 37 is provided on the side of the mounting slot 36 near the wire drum 4. A sleeve 6 and an insertion rod 61 are inserted into the wire drum 4. A third spring 62 is provided inside the sleeve 6 at the end near the insertion rod 61. The end of the insertion rod 61 near the third spring 62 is inserted into the sleeve 6. The end of the third spring 62 is fixedly connected to the sleeve 6. A pressure block 63 and a clamping block 65 are provided on the sleeve 6 and the insertion rod 61. The pressure block 63 is rotatably connected to the sleeve 6 and the insertion rod 61 via a bearing. A connecting rod 64 is provided on the end of the sleeve 6 and the insertion rod 61 away from the wire drum 4. The end of the connecting rod 64 is fixedly connected to the side plate 66. The clamping slot 37 is adapted to fit the clamping block 65. In this embodiment, the pressure block 63 is made of an elastic material, such as rubber.

[0048] When installing the wire reel 4, first insert one end of the sleeve 6 into the hole inside the wire reel frame 3, then insert the insertion rod 61 from the other side of the hole and push it in along the axial direction of the sleeve 6, so that the front end of the insertion rod 61 gradually embeds into the interior of the sleeve 6, forming a nested structure. Then, the side plates 66 at the ends of the sleeve 6 and the insertion rod 61 are squeezed simultaneously, causing the third spring 62 to be compressed and deformed, and driving the two clamping blocks 65 fixed on the sleeve 6 and the insertion rod 61 to move inward synchronously, reducing the distance between the two clamping blocks 65 so that they can enter between the wire reel frames 3. At the same time, the pressure blocks 63 on both sides of the wire reel frame 3 move toward the side close to the wire reel frame 3 and clamp the wire reel 4. Finally, the clamping blocks 65 are aligned and inserted into the corresponding slots 37, so that the connecting rod 64 falls into the installation slot 36. Under the action of the restoring force of the third spring 62, the clamping block 65 is tightly engaged in the clamping groove 37. At the same time, the conical surface of the pressing block 63 fits tightly against the inner wall of the hole of the wire drum 4 through elastic deformation, and utilizes the dual effects of friction and mechanical locking to ensure that the wire drum 4 is firmly installed in the wire drum rack 3.

[0049] Reference Figure 7 The outer peripheral surface of the pressing block 63 is a tapered working surface.

[0050] By designing the outer circumference of the pressure block 63 as a conical working surface, the tapered structure's guiding effect can be utilized during installation of the wire reel 4 to automatically align the center of the hole in the wire reel 4 with the axis of the pressure block 63, maintaining the coaxial position between the wire reel 4 and the pressure block 63, effectively reducing eccentricity errors caused by installation deviations. Furthermore, the adaptive nature of the tapered surface allows it to closely fit the holes of wire reels of varying inner diameters. When the hole diameter of the wire reel 4 is large, the bottom of the tapered surface can penetrate deeply into the hole to provide support; when the hole is small, the top of the tapered surface can form a limit, thereby expanding the applicability of the pressure block 63 to wire reels 4 of varying specifications and enhancing the versatility and practicality of the device.

[0051] Reference Figure 2 , the liquid level inside the observation box 331 is 50%±10% of the box body height.

[0052] When the liquid level is 50% ± 10% of the box height, there is sufficient liquid mass to generate a restoring force while still leaving space for the liquid to flow freely. When the observation box 331 is tilted, the weight difference caused by the liquid flowing to the lower part creates a torsional force, "pulling" the wire reel rack 3 back to the horizontal position.

[0053] Reference Figure 4 、 Figure 5 and Figure 6 One end of the limiting frame 53 close to the guide block 52 is rotatably connected to a roller 531 .

[0054] The roller 531 is used to replace the limit frame 53 in contact with the guide block 52, and the friction between the limit frame 53 and the guide block 52 is converted from sliding friction to rolling friction. This method can reduce the movement resistance of the guide block 52, making it run more smoothly during the operation.

[0055] Reference Figure 2 A reference line 332 is provided on the side of the observation box 331 .

[0056] After the wire reel 4 is installed, by comparing the liquid level of the observation box 331 with the reference line 332 , it is possible to more intuitively determine whether the wire reel frame 3 is in a horizontal state, and to adjust the state of the wire reel frame 3 accordingly.

[0057] The implementation principle of a high-speed stranding machine for copper cable production in the embodiment of the present application is as follows:

[0058] Before installing the wire reel 4, the electromagnet 56 is connected to an external power source to generate a magnetic force. Since the top plate 57 is made of metal, the top plate 57 moves downward under the magnetic attraction and is adsorbed on the electromagnet 56. The top plate 57 drives the guide block 52 to move downward synchronously through the lifting rod 5, and the first spring 54 is stretched. As the guide block 52 moves downward, its inclined surface pushes the limit frame 53 to move laterally toward the support frame 352, and the second spring 55 is compressed. When the limit frame 53 moves into place, the end of the limit frame 53 can clamp the outer side of the movable part 353, limiting the rotation of the movable part 353. At the same time, the lifting rod 5 drives the arc-shaped pressure plate 51 to move downward, so that it is tightly pressed on the rotating shaft 31. With the mutual cooperation of the rubber pad 511 and the striped protrusion 311, the friction between the rotating shaft 31 and the kit 35 is increased, thereby fixing the kit 35. Since the movable part 353 is stuck by the limiting frame 53 and cannot rotate, the position of the fixing rod 34 is also fixed, thereby stably fixing the wire drum frame 3 to prevent it from swinging left and right, making it easier to install the wire drum 4.

[0059] When installing the wire reel 4, first insert one end of the sleeve 6 into the hole inside the wire reel frame 3, then insert the insertion rod 61 from the other side of the hole and push it axially along the sleeve 6. Then, squeeze the side plates 66 at the ends of the sleeve 6 and the insertion rod 61 at the same time, so that the third spring 62 is compressed and deformed, and the distance between the two clamping blocks 65 is reduced, allowing it to enter between the wire reel frames 3. At the same time, the pressure blocks 63 on both sides of the wire reel frame 3 move toward the side close to the wire reel frame 3 and clamp the wire reel 4. The tapered working surface of the pressure block 63 can keep the wire reel 4 and the pressure block 63 coaxial. Finally, align the clamping block 65 and insert it into the corresponding slot 37, so that the connecting rod 64 falls into the installation slot 36. Under the action of the restoring force of the third spring 62, the installation of the wire drum 4 in the wire drum frame 3 can be completed, and then the power supply of the electromagnet 56 is cut off. Under the action of the first spring 54, the lifting rod 5 moves upward and resets, and the second spring 55 drives the limit frame 53 to reset and disengage from the movable part 353, so that the limit on the movable part 353 can be released, and the leveling mechanism can return to normal working state.

[0060] After the wire reel 4 is installed on the wire reel frame 3, if the wire reel frame 3 becomes tilted, it can be leveled by rotating the turntable 324. The rotation of the turntable 324 drives the screw 322 to rotate. Because the connecting plate 321 is threadedly connected to the screw 322, and the top of the connecting plate 321 is slidably connected to the bottom groove of the crossbar 32, when the screw 322 rotates, the connecting plate 321 moves along the axis of the screw 322. The connecting plate 321 drives the leveling block 323 to move in the opposite direction of the tilt of the wire reel frame 3. By adjusting the position of the leveling block 323, the force distribution of the wire reel frame 3 is changed, and the wire reel frame 3 is restored to a horizontal state, providing a basic guarantee for the stability of the subsequent wire payout.

[0061] After starting the motor 11, its output end drives the pipe cage 2 to rotate around its own axis on the base frame 1 through a belt drive mechanism, achieving the release of the single-strand wire and the subsequent twisting operation. During the payout process, when the reel frame 3 tilts, the fixed rod 34 will follow the synchronous tilt. The fixed rod 34 drives the movable member 353 to rotate through the bar hole. As a result, the movable member 353 drives the lever 333 to tilt in the opposite direction. Under the action of the lever 333, the observation box 331 rotates in the opposite direction of the tilt of the reel frame 3. The liquid in the observation box 331 flows toward the lower side due to gravity. The displacement of the liquid mass generates a reset torque, which prompts the reel frame 3 to automatically return to a horizontal position, suppressing the swing of the reel frame 3 and improving the uniformity and stability of the payout.

[0062] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
