A wire traction assembly is provided at the top of the support. A vertical guide is provided on the support between each wire feeding assembly and the wire traction assembly. A wire outlet hole is provided on the cabinet. The advantages of this invention are: the vertical guide guides the wire to the wire traction assembly, and after being pulled by the wire traction assembly, it is led out from the wire outlet hole.

Description

Technical Field

[0001] This invention relates to a wire feeding trolley. Background Technology

[0002] Cable laying trolleys are an indispensable auxiliary device in the production, laying, and processing of wires, cables, and optical fibers. Their main function is to support the wire reels and ensure smooth cable laying, guaranteeing the smooth progress of subsequent processing or laying operations. Most existing cable laying racks use multiple sets of cable laying components arranged side-by-side, staggered, or in multiple columns on a support frame. While this arrangement allows for simultaneous laying of multiple sets of wires, it has significant drawbacks: Firstly, multiple columns or side-by-side arrangements result in excessive lateral space occupied by the cable laying rack, making it bulky and inconvenient for placement and handling in confined working environments (such as construction sites or small production lines). Furthermore, the spacing between multiple cable laying components is difficult to control precisely, easily leading to wire crossing, tangling, and knotting, affecting not only the smoothness of laying but also causing wire loss. Secondly, multiple columns cause uneven stress distribution on the support frame, with concentrated local stress. Over time, this can lead to deformation, shaking, and even structural damage, affecting the service life and reliability of the cable laying rack. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of wire loss caused by existing wire feeding trolleys during wire feeding. A new wire feeding trolley is proposed, which guides the wire to a wire traction assembly via a vertical guide, and then pulls the wire out through the outlet hole after being pulled by the wire traction assembly. Since the wire traction assembly is mounted on a bracket, the entire structure is more compact, and the path between the wire feeding assembly and the wire traction assembly is fixed and minimized, reducing wire vibration and accidental friction points, effectively protecting the wire sheath, and reducing the defect rate. The vertical guide also constrains the wire, making the wire tension more stable.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a wire feeding trolley, including a frame and a plurality of wire feeding assemblies mounted on the frame. The frame includes a cabinet and a moving assembly. The moving assembly is located at the bottom of the cabinet. The cabinet is provided with a bracket for mounting the wire feeding assemblies, and the wire feeding assemblies are arranged in a single row along the height direction of the bracket. The top of the bracket is provided with a wire pulling assembly. A vertical guide is provided on the bracket between each wire feeding assembly and the wire pulling assembly. The cabinet is provided with a wire outlet hole. The wire on the wire feeding assembly passes through the vertical guide and enters the wire pulling assembly. After being pulled by the wire pulling assembly, it is led out from the wire outlet hole. The cabinet is also provided with a cabinet door, and the cabinet door is detachably mounted on the cabinet.

[0005] Preferably, the wire feeding assembly includes a wire feeding reel, a brake, and a fixing plate. The fixing plate includes a first mounting part and a second mounting part. The wire feeding reel is rotatably connected to the fixing plate through the first mounting part. The brake is mounted on the fixing plate through the second mounting part. The wire feeding reel and the brake are mounted on a bracket along with the fixing plate. The brake is drivenly connected to the wire feeding reel to prevent the wire feeding reel from rotating due to inertia.

[0006] Preferably, the first mounting part is a bearing support disposed on one side of the fixed plate, and the wire reel is rotatably connected to the bearing support. The second mounting part is a mounting support disposed on the other side of the fixed plate. The horizontal axis of the bearing support and the horizontal axis of the mounting support coincide. The mounting support includes a first horizontal part, a second horizontal part, and a vertical part disposed between the first horizontal part and the second horizontal part. Both the first horizontal part and the second horizontal part are provided with flanges connected to the fixed plate. The vertical part is provided with mounting holes for mounting a brake. The brake is detachably mounted on the vertical part by screws. The mounting support is an integral structure.

[0007] Preferably, the wire reel is provided with a connecting part connected to the brake. The connecting part is connected to the brake via a key drive, and the connecting part and the wire reel are an integral structure. One end of the wire reel is provided with a limiting chuck, and the other end of the wire reel is provided with a fixing chuck. The fixing chuck is detachably installed on the other end of the wire reel.

[0008] Preferably, the bracket is provided with several sets of spaced mounting beams along the vertical direction. The fixing plate is installed on the mounting beams by the first bolt. The mounting beam includes two parallel horizontal bars with horizontal through grooves. The fixing plate is provided with vertical strip holes. The first bolt passes through the vertical strip holes and horizontal through grooves in sequence and is then locked by a nut.

[0009] Preferably, the wire traction assembly includes a mounting frame, a traction roller, and multiple pressure roller assemblies. The mounting frame is mounted on a bracket, the traction roller is rotatably connected to the mounting frame, and the multiple pressure roller assemblies are spaced apart along the axial direction of the traction roller on the mounting frame above the traction roller. Each pressure roller assembly and the traction roller form a traction gap for the wire to pass through. The mounting frame is provided with a drive assembly for driving the traction roller to rotate. On the wire inlet side of the mounting frame, there is a feed guide assembly corresponding to the traction gap. On the wire outlet side of the mounting frame, there is a discharge guide assembly corresponding to the traction gap. The outer wall of the traction roller is covered with a wear-resistant and smooth layer.

[0010] Preferably, the lower pressure roller assembly includes a lifting drive, a roller seat, and a lower pressure roller. The lifting drive is mounted on a mounting frame, and its output end is connected to the roller seat. The lower pressure roller is rotatably connected to the roller seat.

[0011] Preferably, the drive assembly includes a positioning plate, a positioning shaft, and a servo motor, wherein the positioning plate is driven by... The second bolt is installed on the mounting bracket, one end of the positioning shaft is fixedly connected to the positioning plate, the servo motor includes a motor base, the motor base is installed on the other end of the positioning shaft by a third bolt, and the servo motor is connected to the traction roller by belt drive.

[0012] Preferably, both the feeding guide assembly and the discharging guide assembly include a guide ring and a guide wheel. The wire passes through the guide wheel and the guide ring sequentially from the feeding side and is fed into the traction gap. After being pulled by the traction roller and the lower pressure roller assembly, it passes through the guide ring and the guide wheel sequentially from the discharging side and is fed forward. The guide ring is detachably mounted on the mounting frame by a screw, and the guide wheel is detachably mounted on the mounting frame by a mounting base. The mounting base includes a first horizontal plate, a second horizontal plate, and a vertical plate disposed between the first horizontal plate and the second horizontal plate. The first horizontal plate is fixedly mounted on the mounting frame, and the second horizontal plate is provided with a wheel frame. The guide wheel is rotatably connected to the wheel frame, and the vertical plate is provided with a through hole for the wire to pass through.

[0013] Preferably, the vertical guide portion includes a connecting plate and a guide sleeve, one end of the connecting plate is mounted on the bracket by a bolt assembly, and the guide sleeve is detachably mounted on the connecting plate.

[0014] In summary, the advantages of this invention are as follows: The vertical guide portion guides the wire to the wire traction assembly, which then pulls it out through the outlet hole. Since the wire traction assembly is mounted on the bracket, the entire structure becomes more compact, and the path between the wire feeding assembly and the wire traction assembly is fixed and minimized, reducing wire vibration and accidental friction points, effectively protecting the wire sheath, and lowering the defect rate. The vertical guide portion constrains the wire, making the wire tension more stable. Furthermore, the bracket, located inside the cabinet, effectively isolates airflow, dust, and human contact. Secondly, arranging multiple wire feeding assemblies in a single row along the height direction on the bracket significantly shortens the horizontal width of the entire bracket, thereby optimizing the width of the entire frame and effectively reducing the overall footprint, allowing the entire frame to operate flexibly in confined installation environments. Furthermore, the single-row arrangement ensures a vertically uniform load distribution on the support structure, simplifying the overall support design. This reduces the length and quantity of profiles required for the entire wire feeding trolley, lowering manufacturing costs and processing difficulty. It also reduces the overall weight of the wire feeding trolley, facilitating its movement by operators and reducing the load requirements on the moving components, thus significantly extending their lifespan. Moreover, each wire feeding component is independent, eliminating issues such as wire crossing, tangling, or knotting, thereby improving wire feeding efficiency. Finally, the cabinet door and body are designed for detachable installation. When the wire feeding trolley needs maintenance or additional wire, the cabinet can be fully opened, completely exposing the work area. Operators can perform wire threading and connection operations from the front without obstruction, providing great operational convenience and significantly improving maintenance and installation efficiency.

Detailed Implementation

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a wire feeding trolley includes a frame A and multiple wire feeding components B mounted on the frame A. The frame A includes a cabinet A1 and a moving component A2. The moving component A2 is located at the bottom of the cabinet A1. The cabinet A1 contains a bracket A3 for mounting the wire feeding components B, and the wire feeding components B are arranged in a single row along the height direction of the bracket A3. The top of the bracket A3 is provided with a wire pulling component C. A vertical guide part D is provided on the bracket A3 between each wire feeding component B and the wire pulling component C. The cabinet A1 has a wire outlet hole A11. The wire B6 on the wire feeding component B passes through the vertical guide part D and enters the wire pulling component C. After being pulled by the wire pulling component C, it is led out from the wire outlet hole A11. The cabinet A1 also has a cabinet door A4, and the cabinet door A4 is detachably mounted on the cabinet A1.

[0018] The wire is guided to the wire traction assembly C by the vertical guide D, and then pulled out from the outlet hole A11 after being pulled by the wire traction assembly C. Since the wire traction assembly C is set on the bracket A3, it makes the entire structure more compact and fixes the path between the wire release assembly B and the wire traction assembly C, ensuring the shortest path and reducing wire vibration and accidental friction points. This effectively protects the wire sheath and reduces the defect rate. The vertical guide D constrains the wire, making the wire tension more stable. Moreover, the bracket A3 is set inside the cabinet A1, which effectively isolates airflow, dust, and human contact. Furthermore, arranging multiple wire release assemblies B in a single row along the height direction on the bracket A3 can significantly shorten the width of the entire bracket A3 in the horizontal direction, thereby optimizing the width of the entire frame A and effectively reducing the overall footprint, allowing the entire frame A to move flexibly in narrow installation environments. Furthermore, the single-row arrangement ensures that the load borne by the bracket A3 is vertically and evenly distributed, simplifying the structure of the entire bracket A3. This reduces the length and quantity of profiles required for the entire wire feeding trolley, lowering its manufacturing cost and processing difficulty. It also reduces the weight of the entire wire feeding trolley, making it easier for operators to move the trolley. This reduces the load requirements on the moving component A2, significantly extending its service life. Moreover, each wire feeding component B is independent, eliminating problems such as wire crossing, tangling, and knotting, thus improving wire feeding efficiency. Finally, the cabinet door A4 and cabinet body A1 are designed for detachable installation. When the wire feeding trolley needs maintenance or wire replenishment, cabinet body A1 can be fully opened, completely exposing the entire working area. Operators can perform wire threading and connection operations from the front without obstruction, providing great operational convenience and significantly improving maintenance and installation efficiency.

[0019] The wire feeding assembly B includes a wire feeding reel B1, a brake B2, and a fixing plate B3. The fixing plate B3 includes a first mounting part B31 and a second mounting part B32. The wire feeding reel B1 is rotatably connected to the fixing plate B3 via the first mounting part B31. The brake B2 is mounted on the fixing plate B3 via the second mounting part B32. The wire feeding reel B1 and the brake B2 are mounted on the bracket A3 along with the fixing plate B3. The brake B2 is drive-connected to the wire feeding reel B1 to prevent the wire feeding reel B1 from rotating due to inertia. The wire reel B1 and brake B2 are mounted on the fixed plate B3 via the first mounting part B31 and the second mounting part B32, respectively, making the entire wire feeding assembly B a single unit. The overall structure is compact and easy to install and disassemble. Assembly can be completed simply by mounting the fixed plate B3 on the bracket A3, without the need to assemble individual components, which greatly improves installation efficiency. At the same time, it is convenient for operators to maintain and operate each wire feeding assembly B independently. In addition, the number of wire feeding assemblies B can be flexibly increased or decreased according to wire feeding needs to meet different wire feeding requirements. Finally, the brake B2 is connected to the wire reel B1 for transmission, which can effectively suppress the rotation of the wire reel B1 due to inertia, avoid wire slack, tangling or mess, and ensure wire feeding accuracy.

[0020] The first mounting part B31 is a bearing support disposed on one side of the fixed plate B3. The fixed plate B3 has a fixing hole B34 for fixing the bearing support. The unwinding reel B1 is rotatably connected to the bearing support. The second mounting part B32 is a mounting support disposed on the other side of the fixed plate B3. The horizontal axis of the bearing support coincides with the horizontal axis of the mounting support. The mounting support includes a first horizontal part B321, a second horizontal part B322, and a vertical part B323 disposed between the first horizontal part B321 and the second horizontal part B322. Both the first horizontal part B321 and the second horizontal part B322 have flanges B324 connected to the fixed plate B3. The vertical part B323 has a mounting hole B325 for mounting a brake B2. The brake B2 is detachably mounted on the vertical part B323 by screws B4. The mounting support is an integral structure, with the first mounting part B31 configured as... The bearing support, because the wire reel B1 is rotatably connected within the bearing support, reduces rotational friction resistance, thereby reducing wire wear and power loss during the wire feeding process. The second mounting part B32 is configured as a mounting support, facilitating the disassembly, repair, and replacement of the brake B2, thus reducing maintenance costs. In this embodiment, the brake B2 can be a magnetic powder brake, a pneumatic brake, or an electromagnetic brake, allowing for the installation of different brakes according to different needs. Furthermore, the bearing support is positioned on one side of the fixed plate B3, and the mounting support is positioned on the other side. Since the horizontal axes of the bearing support and the mounting support coincide, the coaxiality of the transmission between the brake B2 and the wire reel B1 is ensured, avoiding problems such as transmission jamming and brake B2 failure due to axial deviation, thus guaranteeing stable braking performance. Moreover, during installation, the wire reel B1 and the brake B2 are independent of each other, preventing spatial interference and significantly improving installation quality. The mounting bracket includes a first horizontal section B321, a second horizontal section B322, and a vertical section B323 disposed between the first horizontal section B321 and the second horizontal section B322. Both the first horizontal section B321 and the second horizontal section B322 are provided with flanges B324 connected to a fixing plate B3. The vertical section B323 is provided with mounting holes B325 for mounting a brake B2. The brake B2 is mounted on the vertical section B323 by screws B4. The flanges B324 can increase the height of the first horizontal section B321. The contact area between part B321, the second horizontal part B322 and the fixed plate B3 is increased, resulting in more even force distribution after connection. This prevents the mounting bracket from shaking or shifting during braking, ensuring the stability of the brake B2 installation. Secondly, mounting holes B325 are provided in the vertical part B323, which facilitates the positioning of the brake B2 and the alignment of the screws B4, making it easier to install and remove the brake B2. Moreover, the entire structure can effectively disperse the reaction force generated when the brake B2 is working, improving the structural strength of the mounting bracket.In this embodiment, the flange B324 can be installed on the fixed plate B3 using a magnetic structure or fasteners. The mounting bracket is an integrated structure, which simplifies the installation process between the various components of the mounting bracket, eliminates splicing gaps and assembly errors, and results in higher overall structural rigidity, stronger resistance to deformation, and the ability to withstand the impact of the brake B2 during long-term operation, thus extending the service life of the entire mounting bracket. At the same time, the integrated structure reduces the number of parts, thereby reducing assembly procedures and costs.

[0021] The wire reel B1 is provided with a connecting part B11 connected to the brake B2. The connecting part B11 and the brake B2 are connected by a key drive. The setting of the connecting part B11 eliminates the need for additional intermediate transmission components, making the overall structure simpler and reducing the overall volume of the wire feeding assembly B. It also facilitates the assembly of the brake B2 and ensures the coaxiality of the transmission between the brake B2 and the wire reel B1. The key drive has the characteristics of simple structure, high transmission accuracy, and strong load-bearing capacity. It can ensure that the braking torque of the brake B2 is stably transmitted to the wire reel B1, with a faster response speed and avoiding slippage. Moreover, the key structure is simple, easy to install and disassemble, and convenient for later maintenance. The connecting part B11 and the pay-off reel B1 are an integral structure. Setting the connecting part B11 and the pay-off reel B1 as an integral structure simplifies the installation process between the connecting part B11 and the pay-off reel B1, strengthens the overall structure, can withstand greater transmission torque, and prevents the connecting part B11 and the pay-off reel B1 from separating or breaking due to long-term stress. At the same time, it reduces the number of parts, reduces assembly errors and production costs. One end of the wire reel B1 is provided with a limiting chuck B12, and the other end of the wire reel B1 is provided with a fixing chuck B13. The fixing chuck B13 is detachably installed on the other end of the wire reel B1. The setting of the limiting chuck B12 and the fixing chuck B13 can fix both ends of the wire reel, prevent the axial movement of the wire reel during the wire feeding process, and ensure neat wire feeding. Secondly, since the fixing chuck B13 is detachably installed on the other end of the wire reel B1, it is convenient for the installation and replacement of the wire reel, and can adapt to wire reels of different widths, improving the overall versatility and meeting the wire feeding needs of various specifications. In this embodiment, the other end of the wire reel B1 is provided with an external thread, the fixing chuck B13 is provided with a through hole, and the other end of the wire reel B1 is provided with a fixing nut B51, which facilitates the installation and removal of the fixing chuck B13.

[0022] The support A3 along the vertical direction is provided with several sets of equally spaced mounting beams A31. The fixing plate B3 is installed on the mounting beams A31 by the first bolt B5. The mounting beams A31 are equally spaced along the vertical direction of the support A3, so that each wire laying component B is arranged vertically and equally spaced, and the wires do not interfere with each other and avoid crossing and tangling. In addition, the fixing plate B3 is connected to the mounting beams A31 by the first bolt B5, which is convenient for disassembly and assembly. The number or spacing of the fixing plates B3 can be adjusted according to the needs to meet the operation requirements of different wire laying volumes. The mounting beam A31 includes two parallel horizontal bars A32. The horizontal bars A32 have horizontal slots A33, and the fixing plate B3 has vertical slots B33. The first bolt B5 passes through the vertical slots B33 and horizontal slots A33 sequentially and is then locked by a nut B51. By providing horizontal slots A33 on the horizontal bars A32 and vertical slots B33 on the fixing plate B3, and by locking the first bolt B5 through the vertical slots B33 and horizontal slots A33 with a nut B51, the fixing plate B3 can be finely adjusted in both horizontal and vertical directions to meet different installation requirements and adapt to different working spaces and layout angles. Furthermore, setting the mounting beam A31 as two parallel horizontal bars A32 improves its load-bearing capacity, effectively distributes the weight of the fixing plate B3, prevents deformation of the mounting beam A31, and ensures the overall structural stability.

[0023] The wire traction assembly C includes a mounting frame C1, a traction roller C2, and multiple pressure roller assemblies C3. The mounting frame C1 is mounted on a bracket A3. The traction roller C2 is rotatably connected to the mounting frame C1. The multiple pressure roller assemblies C3 are spaced apart along the axial direction of the traction roller C2 on the mounting frame C1 above the traction roller C2. Each pressure roller assembly C3 and the traction roller C2 form a traction gap C4 for the wire to pass through. The mounting frame C1 is provided with a drive assembly C5 for driving the traction roller C2 to rotate. On the wire inlet side of the mounting frame C1 of the traction roller C2, there is a feed guide assembly C6 corresponding to the traction gap C4. On the wire outlet side of the mounting frame C1 of the traction roller C2, there is a discharge guide assembly C7 corresponding to the traction gap C4. The outer wall of the traction roller C2 is covered with a wear-resistant smooth layer C20.

[0024] By setting multiple pressure roller assemblies C3 at axial intervals along the traction roller C2 on the mounting frame C1 above the traction roller C2, and since each pressure roller assembly C3 forms a traction gap C4 between itself and the traction roller C2 for the wire to pass through, multiple independent traction channels can be formed on the mounting frame C1. This allows the entire mounting frame C1 to simultaneously traction multiple wires, greatly improving production efficiency. Moreover, the multiple pressure roller assemblies C3 are independent of each other and can adapt to different traction requirements. When it is necessary to change the wire specification or one of the rollers is damaged, it can be adjusted or replaced individually without affecting the operation of other channels. In addition, the traction roller and the pressure roller assembly C3 increase the contact area of ​​the wire in the traction gap C4, stabilizing the friction and thus providing a strong and uniform traction force, effectively preventing slippage. This is especially suitable for wires with high traction tension requirements, smooth surfaces, or varying diameters. Furthermore, the wire moves in a rolling motion. Dynamic friction greatly reduces the risk of scratching or flattening the wire surface, ensuring wire quality. Secondly, multiple traction channels are driven by the same traction roller, which makes the entire structure more compact, saves installation space, and greatly improves the space utilization of the mounting frame C1. On the other hand, it ensures that the linear speed of each wire is absolutely synchronized, effectively avoiding slight speed differences caused by multiple independent drive sources. Finally, feeding guide components C6 and discharging guide components C7 are respectively set on the mounting frame C1 on the wire inlet side and the wire outlet side of the traction roller C2. Since the feeding guide components C6 and the discharging guide components C7 correspond one-to-one with the traction gap C4, it ensures that the paths of each wire are independent when entering and leaving the traction gap C4, effectively preventing multiple wires from interfering with each other, tangling or scratching each other when running at high speed, greatly reducing the risk of wire breakage and skipping, and ensuring the stability and reliability of equipment operation. The wear-resistant and smooth layer C20 serves two purposes: firstly, it enhances the wear resistance of the traction roller C2, extending its service life; secondly, it reduces the frictional resistance between the traction roller C2 and the wire, preventing scratches and wear on the wire surface, effectively protecting the wire surface quality, and reducing waste generation. Thirdly, it effectively improves the fit between the traction roller C2 and the wire, reducing slippage, ensuring stable transmission of traction power, improving traction accuracy and stability, and guaranteeing synchronous and uniform traction of multiple wires, avoiding speed deviations caused by slippage. Finally, placing the mounting bracket on the support ensures the entire wire traction assembly is stably installed on the support.

[0025] The lower pressure roller assembly C3 includes a lifting drive component C31, a roller seat C32, and a lower pressure roller C33. The lifting drive component C31 is mounted on a mounting frame C1, and its output end is connected to the roller seat C32. The lower pressure roller C33 is rotatably connected to the roller seat C32. By configuring the lower pressure roller assembly C3 with the lifting drive component C31, roller seat C32, and lower pressure roller C33, and because the roller seat C32 is connected to the output end of the lifting drive component C31, and the lower pressure roller C33 is rotatably connected to the roller seat C32, the height of the lower pressure roller C33 can be flexibly adjusted, thereby adjusting the size of the traction gap C4. This allows for adaptation to wires of different diameters and thicknesses, significantly improving versatility. Furthermore, by rotatably connecting the lower pressure roller C33 to the roller seat C32, the lower pressure roller C33 moves with the roller seat C32 during traction. The wire rotates synchronously, reducing sliding friction between the lower pressure roller C33 and the wire, reducing surface wear, and decreasing traction resistance, thus improving traction efficiency. Additionally, the roller seat C32 provides stable support for the lower pressure roller C33, ensuring the stability of its downward pressure and the uniformity of the traction gap C4, preventing uneven force on the wire during traction and thus avoiding deviation. The lifting drive component C31 can be flexibly installed with different types depending on the actual working conditions. The lifting drive component C31 can be a lifting cylinder or a lifting push rod. This embodiment prioritizes the use of a lifting cylinder, which has a simple drive structure, is easy to maintain, has a low failure rate, and is suitable for long-term continuous operation in industrial settings. Furthermore, the pressure exerted by the lower pressure roller C33 on the wire can be controlled by adjusting the cylinder pressure, preventing excessive pressure from damaging the wire or insufficient pressure from causing slippage.

[0026] The drive assembly C5 includes a positioning plate C51, a positioning shaft C52, and a servo motor C53. Plate C51 is mounted on mounting bracket C1 by a second bolt C54. One end of the positioning shaft C52 is fixedly connected to the positioning plate C51. The servo motor C53 includes a motor base C531, which is mounted on the other end of the positioning shaft C52 by a third bolt C55. The servo motor C53 is connected to the traction roller C2 via a belt C56. The servo motor C53 can achieve precise traction speed adjustment and stable speed, and can achieve stepless speed regulation to adapt to the traction speed requirements of different wire specifications. Furthermore, the servo motor C53 has a fast response, enabling rapid start-stop and speed adjustment to ensure the speed consistency of multiple wires being traction synchronously, thus improving traction accuracy. The servo motor C53 and the traction roller C2 are connected via a belt C56, which provides buffering and shock absorption. This design effectively absorbs the vibrations generated by the servo motor C53 during operation, preventing the vibrations from being transmitted to the traction roller C2 and preventing wire traction deviation and wear caused by vibrations. It also protects the servo motor C53 and the traction roller C2, extending the overall service life of the equipment. Furthermore, the entire drive structure is compact and easy to install. Finally, since the positioning plate C51 is mounted on the mounting bracket C1, and one end of the positioning shaft C52 is fixedly connected to the positioning plate C51, and the servo motor C53 is mounted on the positioning shaft C52, the installation position of the servo motor C53 can be accurately positioned. Additionally, the positioning shaft C52 can be replaced with different lengths to meet actual installation needs, or adjusting shims and / or adjusting nuts B51 can be installed on the second bolt C54 and / or the third bolt C55 to adjust the installation position of the servo motor C53, satisfying different installation requirements.

[0027] Both the feeding guide assembly C6 and the discharging guide assembly C7 include a guide ring C8 and a guide wheel C9. The feeding guide assembly C6 and the discharging guide assembly C7 are formed by the guide ring C8 and the guide wheel C9. The guide wheel C9 reduces sliding friction between the wire and the guiding components, reducing wear on the wire surface. The guide ring C8 precisely limits the direction of the wire, preventing wire deviation and swaying, improving the guiding accuracy of a single wire, and ensuring that each wire always runs along a preset trajectory. This prevents traction slippage and wear caused by deviation when the wire enters the traction gap C4, while also ensuring straightness when exiting the wire. The wire passes sequentially through the guide wheel C9 and the guide ring C8 from the feeding side into the traction gap C4. After being pulled by the traction roller C2 and the lower pressure roller assembly C3, the wire is fed forward from the output side through the guide ring C8 and the guide wheel C9. The guide ring C8 is detachably mounted on the mounting frame C1 by the screw C81. The screw C81 is easy to install, and the installation height of the ring can be adjusted according to different wires to adapt to different wires.
