Description

Technical Field

[0001] The invention relates to the technical field of enameled wire production, in particular to a wire splitting tool used for enameled wire production. Background Art

[0002] Enameled wire refers to a wire with an insulating coating on the surface of the metal conductor. It is widely used in the winding process of motors, transformers and various coils. In the production of enameled wire and the subsequent wire splitting and winding process, in order to ensure the quality and winding efficiency of the enameled wire, it is usually necessary to use a dedicated wire splitting tool to split, tension and neatly wind the wire. Most of the existing wire splitting tools can achieve basic winding functions, but in the actual use process, there are still some problems as follows: In existing wire splitting and winding devices, the installation and removal of the wire take-up roller often requires cumbersome assembly steps or the use of additional auxiliary tools, which results in a long time spent on replacing wire take-up rollers of different specifications or empty or full states, and it is difficult to adapt to different production and specification requirements in a timely manner. Some devices have a single fixed structure and cannot be quickly adjusted and stably clamped according to wire take-up rollers of different diameters or lengths.

[0003] During the wire splitting and winding process, if the relative position of the wire guide mechanism and the winding roller cannot be finely adjusted or the adjustment is not convenient, it is easy to cause the enameled wire to be misaligned or clustered during the winding process. In addition, if there is a lack of effective reverse movement and re-wire function after the single-layer winding, the wiring direction of the enameled wire is difficult to change in time, which can easily lead to the wire bundle being staggered or even tangled, affecting the winding quality.

[0004] When winding the enameled wire, appropriate tension is required to ensure neat winding. However, the pressure rollers or guide wheels of many traditional wire splitting tools can only provide fixed pressure or position. Once the diameter or winding thickness of different batches of enameled wires changes, the elastic adjustment cannot be carried out in time, which may easily cause the wire to be too loose or too tight, or the wire to be damaged. If there is no reliable fitting structure, the enameled wire will often become loose at the end of the wire splitting and winding, affecting the subsequent processes.

[0005] In order to make the enameled wire evenly wound in layers on the surface of the take-up roller, the adjustment of the wire entry angle is very important in some application scenarios. However, some devices have a relatively simple way to adjust the wire entry angle or require multiple operations to complete, and the adjustment efficiency is not high. In addition, if the adjustment structure lacks a reliable locking method, it may become loose during long-term operation, causing the wire entry guide mechanism to deviate, thereby affecting the wire separation accuracy.

[0006] In summary, the existing wire splitting and winding devices used in enameled wire production have certain needs for improvement in terms of the wire take-up roller fixing method, flexible adjustment of the wire splitting conductor mechanism, tension force control, and wire entry angle adjustment. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides a wire splitting tool for enameled wire production, which can conveniently install or disassemble the wire taking-up roller, provide flexible tensioning and wire splitting guide adjustment functions, and effectively prevent the wire from loosening after the wire splitting and winding is completed.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: A wire splitting tool for enameled wire production, comprising a bottom plate and a wire take-up roller, wherein the bottom plate is fixed to the ground surface by bolts, first support plates are vertically arranged at both ends of the upper surface of the bottom plate, two second support plates are fixed to the upper surface of the bottom plate, and the two second support plates are placed between the two first support plates, and two wire take-up rollers are installed and are placed between the first support plate and the second support plate respectively; A linkage clamping mechanism is provided between the two second support plates, and the linkage clamping mechanism is used to synchronously clamp and fix the take-up rollers on both sides; The upper surface of the bottom plate is provided with a wire loosening prevention mechanism, which is used to squeeze the wire take-up roller during wire take-up to prevent the enameled wire from loosening; A wire entry angle adjustment mechanism is installed between the two first support plates, and the wire entry angle adjustment mechanism is used to adjust the wire entry angle when the enameled package is wound after the wires are divided.

[0011] Furthermore, the anti-loosening wire mechanism is placed under the two wire-taking rollers, and the anti-loosening wire mechanism includes two pushing cylinders vertically fixed on the upper surface of the bottom plate, and an arc-shaped extrusion plate is laterally fixed on the output end of the pushing cylinder, and the upper surface of the arc-shaped extrusion plate is attached to the bottom of the enameled wire on the inner side of the wire-taking roller.

[0012] Further, a support bar is transversely fixed on the inner side of the first support plate. The wire inlet angle adjusting mechanism further includes a rack sliding inside the support bar and a fixed disk on one side of the center of the upper surface of the bottom plate. The rack meshes with the toothed disk, and a connecting cross bar is transversely fixed between the front ends of the two racks.

[0013] Further, a control rod is rotatably installed on one side of the fixed disk. An arc-shaped track groove is formed on the surface of the fixed disk, which is concentric with the rotation axis of the control rod. A through groove is formed on the surface of the control rod, and the connecting cross bar passes through the through groove.

[0014] Further, a handle is fixed to the end of the control rod. A locking knob penetrates through the inner side of the arc-shaped track groove, and the end of the locking knob is screwed onto the control rod.

[0015] Further, the wire inlet angle adjusting mechanism includes toothed disks respectively rotatably installed on the inner sides of the two first support plates. The toothed disks are provided with extension plates forward. Two wire inlet guiding mechanisms are slidably installed between the two extension plates; The wire inlet guiding mechanism includes a movable block screwed on the surface of a lead screw, and the wire inlet guiding mechanism is used to guide the separated enameled wire. A moving control motor is fixed on the outside of one of the extension plates. A track rod is fixedly arranged between the two extension plates, and a lead screw is also rotatably installed between the two extension plates. The end of the lead screw is fixed on the moving control motor.

The adjusting nut is placed below the support cross plate. A spring is sleeved on the surface of the sliding rod. The spring is placed between the support cross plate and the adjusting nut.

[0017] The present invention provides a wire splitting tooling for enameled wire production. It has the following beneficial effects: By improving the cooperation between the double threaded rod and the moving block in the linkage clamping mechanism, the equipment can achieve the rapid installation and disassembly of wire reels of different sizes without the aid of additional tools; when the double threaded rod and the moving block move synchronously in opposite directions, the distance between the movable extrusion cone head and the fixed cone head can be precisely adjusted, so as to ensure the clamping stability while meeting the assembly requirements of wire reels of different specifications, and realize the double-station wire splitting operation; this echoes the problem of the inflexible fixing method of the wire reel mentioned in the background technology, and can significantly shorten the roll changing time and improve the production efficiency.

[0018] By setting a gear disk, a lead screw and a supporting moving control motor in the wire inlet angle adjusting mechanism, the wire laying of the enameled wire can be adjusted at multiple angles during the wire splitting and winding processes, and the wire inlet angle can be adjusted according to the material of the enameled wire to ensure the winding tightness. For example, thinner enameled wires have good flexibility but are prone to breakage, and the wire inlet angle can be relatively small, such as 30°-45°, which can reduce the tension and the risk of wire breakage; thicker enameled wires have greater rigidity. In order to enable them to be wound smoothly and ensure the winding tightness, the wire inlet angle can be appropriately larger, around 45°-60°, or the tension of the enameled wire can be controlled by adjusting the angle during winding; when the wire inlet guiding mechanism moves synchronously under the drive of the lead screw, it can carry out layered wire laying of the enameled wire and avoid winding chaos. Combining the deficiency of uneven winding that is prone to occur during the wire splitting and wire laying processes in the background technology, it ensures the smooth running of the enameled wire and improves the overall winding quality in practical applications.

[0019] By setting a pushing cylinder and an arc-shaped extrusion plate in the anti-loosening wire mechanism, the enameled wire can be tightly pressed after the winding is completed to prevent the enameled wire from loosening; By setting a control rod, a locking knob and an arc-shaped track groove, the wire inlet guiding mechanism can accurately guide the enameled wire during the winding process; the change of the spring pre-tightening amount can prevent the enameled wire from being overly loose or overly squeezed, resulting in wire breakage or surface damage. This corresponds to the problem that it is difficult to balance the tension and the winding tightness mentioned in the background technology, and effectively guarantees the quality of the enameled wire while improving the neatness; when the single-layer winding or the requirements for different enameled wire specifications change, the wire inlet angle can be quickly adjusted, and the required position can be fixed by means of the locking knob to avoid loosening and deviation during long-term operation. This corresponds to the current situation that it is difficult to ensure the wire laying accuracy due to inconvenient angle adjustment in the background technology, and significantly improves the wire splitting efficiency and winding quality in practical use.

Specific embodiments

[0022] Next, in combination with the drawings of the present invention, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Refer to Figures 1-9, A wire dividing tool for enameled wire production, including a bottom plate 1 and wire take-up rollers. The bottom plate 1 is fixed to the ground surface by bolts. At both ends of the upper surface of the bottom plate 1, first support plates 11 are vertically arranged. Two second support plates 12 are fixed on the upper surface of the bottom plate 1, and both of the two second support plates 12 are placed between the two first support plates 11. Two wire take-up rollers are installed, and the two wire take-up rollers are respectively installed between the first support plates 11 and the second support plates 12; The bottom plate 1 is made of Q235 steel plate and undergoes overall anti-corrosion spraying treatment. The length of the bottom plate 1 is 2000mm, the width is 800mm, and the thickness is 10mm. The bolts on the bottom plate 1 are M12 type high-strength bolts. Both the first support plates 11 and the second support plates 12 are made of 304 stainless steel plates with a thickness of 8mm. The first support plates 11 and the second support plates 12 are perpendicularly spliced with the bottom plate 1 to enhance the overall stability. Both of the two wire take-up rollers are steel rollers with a diameter of Φ300mm×350mm and a wear-resistant ceramic coating is sprayed on the surface. When the two wire take-up rollers are respectively installed between the first support plates 11 and the second support plates 12, they can be stably installed and quickly disassembled under the action of the linkage clamping mechanism 2. Combining the requirement for quick replacement of the wire take-up roller proposed in the background technology can effectively improve production efficiency. A linkage clamping mechanism 2 is arranged between the two second support plates 12. The linkage clamping mechanism 2 is used to synchronously clamp and fix the wire take-up rollers on both sides; The linkage clamping mechanism 2 includes a number of rotating components and adjustable components to co-axially clamp the wire take-up rollers on the same axis. The linkage clamping mechanism 2 can drive the moving blocks 26 to move synchronously and apply a clamping force through the double threaded rod 25. All components of the linkage clamping mechanism 2 are made of 40Cr alloy steel and undergo quenching treatment. The overall structure of the linkage clamping mechanism 2 can effectively avoid deviations during the clamping process and improve the adaptability to wire take-up rollers with different diameters. Combining the deficiency of the inflexible fixing method of the wire take-up roller in the background technology for improvement. A wire anti-loosening mechanism 3 is installed on the upper surface of the bottom plate 1. The wire anti-loosening mechanism 3 is placed below the two wire take-up rollers. The wire anti-loosening mechanism 3 is used to squeeze the wire take-up rollers during wire taking to prevent the enameled wire from loosening; The wire anti-loosening mechanism 3 is composed of components such as a push cylinder 32, a push rod 33, an arc-shaped extrusion plate 35, and a connecting rod 36. The wire anti-loosening mechanism 3 can tightly press the enameled wire when the wire taking is completed or during a mid-course shutdown for maintenance. The wire anti-loosening mechanism 3 can improve the problem that the enameled wire is wound too loosely, which is inconvenient for subsequent processing, in combination with the background technology. The main material of the wire anti-loosening mechanism 3 is cast iron HT250 and it undergoes rust prevention treatment on the surface. A polymer wear-resistant material is pasted at the position where the arc-shaped extrusion plate 35 contacts the enameled wire to protect the surface of the enameled wire.

[0024] An in-line angle adjustment mechanism 4 is installed between two first support plates 11. The in-line angle adjustment mechanism 4 includes gear discs 41 respectively rotating on the inner sides of the two first support plates 11. The gear discs 41 are provided with extension plates 42 facing forward. A moving control motor 45 is fixed on the outside of one of the extension plates 42. A track rod 43 is fixedly arranged between the two extension plates 42. A lead screw 44 is also rotatably installed between the two extension plates 42. The end of the lead screw 44 is fixed on the moving control motor 45. Two in-line guiding mechanisms 5 are slidably installed between the lead screw 44 and the track rod 43. The two in-line guiding mechanisms 5 respectively correspond to the two take-up rollers; The in-line angle adjustment mechanism 4 is made of 304 stainless steel and is precision laser cut. The diameter of the gear disc 41 is 150 mm and the number of teeth is set to 60 teeth. The extension plate 42 and the track rod 43 are fixed by bolt connection. The model of the moving control motor 45 is 80ST-M02430AC servo motor and it has a rated power of 750 W. The pitch of the lead screw 44 matches the common diameter range of enameled wire. The in-line angle adjustment mechanism 4 can be finely adjusted according to the control requirements of the in-line angle in the background technology to avoid the enameled wire from generating staggered layers or winding chaos during the wire splitting process. The in-line guiding mechanism 5 includes a movable block 51 screwed on the surface of the lead screw 44. The in-line guiding mechanism 5 is used to guide the split enameled wire; The movable block 51 is precision turned from 45# steel and a high-hardness anti-wear bushing is provided at the inner hole position where it cooperates with the lead screw 44. The in-line guiding mechanism 5 can move back and forth along the lead screw 44 and the track rod 43 driven by the moving control motor 45 to achieve layered wire arrangement. The in-line guiding mechanism 5 is improved according to the requirements of preventing uneven winding of the enameled wire in the background technology and can be synchronously matched with the take-up roller for movement. Refer to Figures 1-4 , Fixed cone heads 14 are rotatably installed on the inner sides of both first support plates 11. A servo motor 13 is fixed on the outside of one of the first support plates 11. The fixed cone head 14 is coaxially installed on the output shaft of the servo motor 13. The linkage clamping mechanism 2 includes rotating shafts 21 respectively rotating through the two second support plates 12. The rotating shafts 21 coincide with the axis of the fixed cone head 14; The servo motor 13 adopts the SV-750W series motor and is connected to the fixed cone head 14 through a coupling. The diameter of the fixed cone head 14 is Φ30 mm and it is made of high-quality alloy steel. High-precision bearings are provided at both ends of the rotating shaft 21 and 2# lithium-based grease is used for lubrication. The rotating shaft 21 can drive the movable extrusion cone head 22 to rotate synchronously to achieve the same-direction or reverse driving of the take-up roller. Refer to Figures 2-4, at the mutually facing ends of the two rotating shafts 21, there are respectively fixed movable extrusion cone heads 22, and at the mutually approaching ends of the rotating shafts 21, there are provided limiting plates 23. The limiting plates 23 are placed between the two second support plates 12. Both ends of the wire winding roller are clamped and fixed by the movable extrusion cone heads 22 and the fixed cone heads 14. At the mutually approaching ends of the two rotating shafts 21, there is movably installed a connecting square rod 24. Below the two second support plates 12, there is rotatably installed a double-threaded rod 25. On the surface of the double-threaded rod 25, there are symmetrically screwed moving blocks 26. On the upper surface of the moving blocks 26, there are provided arc-shaped clamping grooves 27. The centers of the arc-shaped clamping grooves 27 coincide with the centers of the limiting plates 23. The lower sides of the limiting plates 23 are placed inside the arc-shaped clamping grooves 27; the movable extrusion cone heads 22 are coated with tungsten carbide to enhance wear resistance. The limiting plates 23 are made of 45# steel with a thickness of 5 mm and are heat-treated. The connecting square rod 24 has a square cross-section of 40×40 mm to ensure high strength. The double-threaded rod 25 has a diameter of 20 mm and is quenched and tempered with 40Cr material. At the mating part of the moving blocks 26 and the double-threaded rod 25, there is a two-way thread to realize the synchronous approaching or separating movement of the two movable extrusion cone heads 22 on both sides. The curvature of the arc-shaped clamping grooves 27 coincides with that of the limiting plates 23 so as not to cause interference during the movement, combined with the requirement of quickly adjusting and installing the wire winding roller in the background technology.

[0025] Refer to Figures 1-3 , the anti-loosening wire mechanism 3 is placed below the two wire winding rollers 6. The anti-loosening wire mechanism 3 includes two push cylinders 31 vertically fixed on the upper surface of the base plate 1. The output ends of the push cylinders 31 are horizontally fixed with arc-shaped extrusion plates 32. The upper surfaces of the arc-shaped extrusion plates are attached to the lower side of the enameled wire inside the wire winding roller 6; the model of the push cylinder 31 is SC63×100 and it adopts a double-acting mode. The anti-loosening wire mechanism 3 can timely press the arc-shaped extrusion plate 32 up and down in combination with the requirements for the adhesion and tightness of the enameled wire in the background technology. Refer to Figures 1-9 , on the inner side surface of the first support plate 11, there is horizontally fixed a support bar 15. The wire inlet angle adjusting mechanism 4 further includes a toothed rod 46 sliding inside the support bar 15 and a fixed disk 48 on one side of the center of the upper surface of the base plate 1. The toothed rod 46 meshes with the toothed disk 41. Horizontally fixed between the front ends of the two toothed rods 46 is a connecting cross bar 47; the length of the support bar 15 is 300 mm and it is made of square steel Q235 - B material. The module of the toothed rod 46 is 2 and it matches the toothed disk 41 to ensure smooth transmission. The fixed disk 48 is made of cast iron HT200 and is machined by turning at the outer circumferential position. The connecting cross bar 47 is a 45# steel round rod with a diameter of Φ16 mm and is fixed to the front ends of the two toothed rods 46 by bolts. In combination with the requirement of flexibly adjusting the wire inlet angle in the background technology, the meshing mode between the toothed rod 46 and the toothed disk 41 of the wire inlet angle adjusting mechanism 4 can realize multi-angle displacement.

[0026] Refer to Figure 5 、 Figure 8 and Figure 9, a control rod 410 is rotatably installed on one side of the fixed disk 48. An arc-shaped track groove 49 is formed on the surface of the fixed disk 48. The arc-shaped track groove 49 is concentric with the rotation axis 21 of the control rod 410. A through groove 411 is formed on the surface of the control rod 410. The connecting cross bar 47 passes through the through groove 411. The control rod 410 can swing within a small range around the center of the fixed disk 48 and the adjustment angle is limited by the arc-shaped track groove 49. The control rod 410 is made of thickened 45# steel and an anti-rust paint is sprayed on its surface. The curvature of the arc-shaped track groove 49 is concentric with the fixed disk 48 and is designed in cooperation with the size of the through groove 411 to facilitate the passing of the connecting cross bar 47. Adjustment at different angles can adapt to the change of the winding angle of the enameled wire on the take-up roller to meet different working conditions.

[0027] Refer to Figures 8-9 , a handle 412 is fixed at the end of the control rod 410. A locking knob 413 penetrates through the inner side of the arc-shaped track groove 49. The end of the locking knob 413 is screwed onto the control rod 410. The handle 412 is made of a mixture of nylon and glass fiber to enhance the holding comfort and anti-slip. The locking knob 413 can be screwed and fixed to the control rod 410 through an M8 thread structure. After the locking knob 413 is locked, the position of the control rod 410 can be reliably fixed to prevent loosening and deviation during the production process. Combining with the precise control requirement of the wire inlet angle in the background technology, it can be quickly loosened and re-locked after the single-layer winding is completed or when the angle needs to be changed due to the change of the enameled wire diameter. Refer to Figures 6-7 , two support plates 52 are vertically arranged on the upper surface of the movable block 51. A roller shaft 53 is rotatably installed between the two support plates 52. An arc-shaped concave surface 531 is formed on the surface of the roller shaft 53. A support cross plate 54 is fixed on the outside of the support plate 52. A sliding rod 55 is vertically and slidably installed on the surface of the support cross plate 54. A fixed rod 56 is arranged above the top between the two sliding rods 55. The fixed rod 56 is placed above the roller shaft 53. A pressure roller 57 is arranged at the center of the fixed rod 56. The pressure roller 57 corresponds to the arc-shaped concave surface 531. The enameled wire passes through between the roller shaft 53 and the pressure roller 57. The support plate 52 is made of A3 steel plate with a thickness of 8 mm. The roller shaft 53 is made of 40Cr and its surface is nitrided to improve the wear resistance. The radius of the arc-shaped concave surface 531 matches the diameter of the common enameled wire to keep the enameled wire stable during passing. The support cross plate 54 has a thickness of 6 mm and is fixed to the movable block 51 by bolts. The sliding rod 55 is made of stainless steel 304 material and its hardness is tested. The fixed rod 56 is a chrome-plated round steel with a diameter of Φ12 mm. The outside of the pressure roller 57 is coated with a wear-resistant rubber layer to stabilize the tension of the enameled wire and avoid damage to the surface of the wire. Refer to Figures 6-7, an adjusting nut 58 is screwed onto the bottom of the sliding rod 55. The adjusting nut 58 is placed below the supporting cross plate 54. A spring 59 is sleeved on the surface of the sliding rod 55. The spring 59 is placed between the supporting cross plate 54 and the adjusting nut 58. The adjusting nut 58 is quenched with 45# steel and precisely adjusted through fine-pitch threads. The spring 59 is made of stainless steel spring steel and the conventional elastic force range is set between 30N and 50N according to the tension requirement of the enameled wire. Tightening the adjusting nut 58 can increase the pre-compression amount of the spring 59, thereby enhancing the downward thrust on the pressure roller 57. Combining the dual requirements for the tension and winding fit of the enameled wire in the background technology, this structure can ensure that the enameled wire remains tight during the winding process and reduce the problem of unstable tension caused by diameter or batch differences. Working principle: When in use, first install the empty wire-receiving roller 6, place the wire-receiving roller 6 between the first supporting plate 11 and the second supporting plate 12, and then initially fix the wire-receiving roller 6 through the fixed cone head 14 and the movable extrusion cone head 22. Then rotate the double-threaded rod 25 to synchronously control the equidistant and reverse movement of the two moving blocks 26. Since the bottom of the limiting plate 23 is placed inside the arc-shaped card slot 27, when the moving block 26 moves, it can drive the rotating shaft 21 to move, so as to adjust the distance between the two movable extrusion cone heads 22 without affecting the rotation of the rotating shaft 21. The two rotating shafts 21 are connected by a connecting square rod 24, so the two rotating shafts 21 can rotate synchronously. By controlling the two moving blocks 26 to move away from each other, the two movable extrusion cone heads 22 are separated, and then the clamping and fixing of the wire-receiving roller 6 are realized. Starting the servo motor 13 can drive the two wire-receiving rollers 6 to rotate synchronously, thereby improving the convenience of installing or disassembling the wire-receiving roller 6.

[0028] Starting the servo motor 13 can drive the wire-receiving roller 6 to rotate, realizing the divided-line winding work. At the same time, the pushing cylinder 31 is adjusted in real time according to the winding size to control the height of the arc-shaped pressing plate 32, so that the upper surface of the arc-shaped pressing plate 32 is closely attached to the wound enameled wire and always adapts to the thickness of the winding. When the divided-line winding ends, the attachment of the arc-shaped pressing plate 32 can squeeze the enameled wire to prevent it from loosening, so as to ensure that the wound enameled wire is wound tightly.

[0029] When the enameled wire is rewound by the wire dividing mechanism, the enameled wire penetrates into the wire inlet guiding mechanism 5 and winds around the surface of the wire take-up roller 6. The moving control motor 45 is started to control the rotation of the lead screw 44, and then the wire inlet guiding mechanism 5 is controlled to move. The pitch of the lead screw 44 is equal to the diameter of the enameled wire. Therefore, when the enameled wire winds around the wire take-up roller 6, the wire inlet guiding mechanism 5 can move synchronously and slowly. After the single-layer winding is completed, the wire inlet guiding mechanism 5 is controlled to move in the reverse direction to dredge and guide the wire dividing winding of the enameled wire to prevent winding chaos. At the same time, during the wire take-up process, the wire inlet angle can be flexibly adjusted according to the wire take-up environment, and the tension of the enameled wire during wire take-up can also be controlled by adjusting the angle. When adjusting, loosen the locking knob 413 and hold the handle 412 to adjust the angle of the control rod 410, and then control the position of the connecting cross bar 47. Through the connecting cross bar 47, the two rack bars 46 can be controlled to move synchronously, and then the angles of the two sprockets 41 can be controlled simultaneously through the meshing of the rack bars 46 and the sprockets 41 to control the angle of the wire inlet guiding mechanism 5 relative to the wire take-up roller 6, and then control the wire inlet angle. After adjustment, it is fixed by screwing the locking knob 413.

[0030] The enameled wire passes through between the roller shaft 53 and the pressure roller 57 to limit it. At the same time, the enameled wire is placed inside the arc-shaped concave surface 531 to ensure the guiding of the enameled wire when the movable block 51 moves horizontally. Due to the existence of the spring 59, the adjusting nut 58 has a downward force, and then the pressure roller 57 has a certain downward pressure on the passing enameled wire to ensure the tension. By screwing the adjusting nut 58, the extrusion force on the spring 59 can be controlled, and then the extrusion of the pressure roller 57 on the enameled wire can be controlled to achieve flexible adjustment.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
