Description

Technical Field

[0001] This invention relates to the field of winding equipment technology, specifically to a wire winding device for fixed length winding. Background Technology

[0002] As a fundamental component in electronics, electrical engineering, communication transmission, industrial assembly, and smart home applications, wires mainly include various types such as electronic wires, power wires, data transmission lines, telephone lines, and optical fibers. They are widely used in various equipment manufacturing, signal transmission, and power transmission processes. Wire winding is a crucial final step in the wire production process. Its core function is to orderly wind and shape the finished wires after cutting, extrusion, shielding, or sheathing, achieving neat storage for subsequent warehousing, transportation, and downstream use.

[0003] Currently, traditional wire winding devices generally suffer from structural design deficiencies. After the winding operation is completed, the wound wire coil fits tightly with the winding roller, lacking a convenient unloading structure. This makes it difficult for operators to quickly and smoothly remove the finished wire coil from the winding roller, resulting in low unloading efficiency and a tendency for the coil to loosen and deform. Furthermore, finished wire coils are typically large in diameter and heavy, making manual handling difficult and posing safety hazards. In actual production, lifting hooks and hoisting devices are often used for lifting and unloading. However, during lifting, the wire coil is susceptible to swaying and shifting in the air due to external forces and inertia, making it highly prone to collisions and scrapes with the winding roller, frame, and other equipment components. This can cause scratches, deformation, or even structural damage to the winding roller.

[0004] Furthermore, existing winding devices often lack precise length control, leading to uneven wire winding lengths and further impacting subsequent packaging and use. To address the shortcomings of existing technologies, such as inconvenient unloading, susceptibility to collision damage during hoisting, and insufficient winding accuracy, there is an urgent need for a wire winding device with a reasonable structure, smooth unloading, high safety, and precise control over the winding length. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a wire winding device for fixed length winding.

[0006] The technical solution adopted by the present invention is as follows: The present invention provides a wire winding device of fixed length, including a driving mechanism and a winding mechanism. The driving mechanism includes a base, a support frame, a rotating shaft, a bearing seat, a reducer, and a drive motor. The support frame is fixedly mounted on the base. The rotating shaft rotatably passes through the support frame via a bearing, and one end of the rotating shaft is fixedly connected to the winding mechanism. The bearing seat, the reducer, and the drive motor are all fixedly mounted on the base. The other end of the rotating shaft rotatably passes through the bearing seat and is connected to the output end of the reducer. The output end of the drive motor is connected to the input end of the reducer. The winding mechanism includes a diameter expansion and contraction component and a wire support component. The wire support component is detachably and slidably mounted around the diameter expansion and contraction component.

[0007] Furthermore, the diameter expansion and contraction assembly includes a hollow roller shaft, a bidirectional screw rotatably connected within the hollow roller shaft, and a support plate. One end of the hollow roller shaft is fixedly connected to one end of a rotating shaft. Threaded cylinders are threadedly connected to the bidirectional screw, and two threaded cylinders are provided, each disposed on one of the two threaded sections of the bidirectional screw. The assembly also includes a connecting arm rotatably connected between the threaded cylinders and the support plate. The support plate is arranged at equal intervals around the hollow roller shaft, and each support plate and the two threaded cylinders are provided with a connecting arm. The hollow roller shaft has an elongated opening along its length for the connecting arm to slide through. A rotating handle is fixedly connected to one end of the bidirectional screw after it rotatably passes through the hollow roller shaft.

[0008] Furthermore, the diameter expansion and contraction assembly also includes a connecting unit, which is equally spaced around the hollow roller shaft. The connecting unit includes a mounting plate and a dovetail guide rail. The mounting plate is fixedly mounted on the circumferential wall at both ends of the hollow roller shaft. Symmetrically distributed tension members are fixedly mounted on the mounting plate. The bottom of the dovetail guide rail is fixedly connected to the tension members at both ends of the hollow roller shaft. The length direction of the dovetail guide rail is parallel to the axis of the hollow roller shaft and is symmetrically located on the side of the support plate away from the hollow roller shaft.

[0009] Furthermore, the tensioning component includes a fixed cylinder, a connecting rod, a sliding block, and a spring. The fixed cylinder is fixedly mounted on the mounting plate, the sliding block is slidably mounted inside the fixed cylinder, the bottom end of the connecting rod is fixedly connected to the sliding block, and the top end of the connecting rod slides through the top of the fixed cylinder and is fixedly connected to the bottom of the dovetail guide rail. The spring is slidably sleeved on the connecting rod and abuts against the top wall of the sliding block and the fixed cylinder.

[0010] Furthermore, the wire support assembly includes an arc-shaped plate and wire blocking units. The axis of the arc-shaped plate coincides with the axis of the hollow roller shaft. The inner wall of the arc-shaped plate facing the hollow roller shaft is provided with a dovetail groove that slides with the dovetail guide rail. The wire blocking units are distributed at both ends of the arc-shaped plate on the side away from the hollow roller shaft and are located between the two sets of dovetail grooves.

[0011] Furthermore, the wire blocking unit includes a baffle, a sliding rod, a second spring, and a limiting plate. The sliding rod slides vertically through the arc-shaped plate. Four sets of locking rods are fixedly provided at the bottom of the baffle, and fixing blocks are fixed between the locking rods. The top of the sliding rod is rotatably positioned between the fixing blocks via a rotating shaft. The baffle rotates along the length of the arc-shaped plate. The limiting plate is fixedly provided at one end of the sliding rod near the hollow roller shaft. The second spring is slidably sleeved on the sliding rod and abuts against the limiting plate and the arc-shaped plate. A slot is provided on the side wall of the arc-shaped plate facing away from the hollow roller shaft, and the bottom end of the locking rod engages with the slot.

[0012] Furthermore, the diameter expansion and contraction assembly also includes an insertion rod, which is fixedly mounted on the side wall of the support plate away from the hollow roller shaft. The bottom wall of the dovetail groove has an insertion hole for inserting the other end of the insertion rod, and the dovetail guide rail has a circular hole for the insertion rod to slide through.

[0013] Furthermore, the diameter expansion and contraction assembly also includes a limiting unit, which is arranged at equal intervals around the hollow roller shaft. The limiting unit includes a support screw and a nut block. The support plate has a clearance opening for the support screw to move through. The nut block is fixed in the middle of the elongated opening. The support screw is threaded through the nut block, and one end of it extends into the hollow roller shaft. The other end moves through the clearance opening and contacts the inner wall of the arc plate on the side facing the hollow roller shaft.

[0014] Furthermore, the drive mechanism also includes an electric push rod, which is fixedly mounted on the top of the support frame, and its output end is fixedly provided with a push plate, which is horizontally located on one side of the baffle.

[0015] Furthermore, the top of the baffle is provided with a binding port, which is located at one end of the baffle to facilitate the threading of the wire connected to the hook, and to facilitate the subsequent lifting of the baffle, the arc plate and the wire bundle.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention uses a photoelectric sensor in conjunction with a baffle to achieve real-time measurement of the number of turns. Every four signals correspond to one turn of wire winding. The controller can count the winding length, effectively solving the problems of inaccurate length control and inconsistent wire roll specifications in traditional winding devices, and significantly improving the wire winding accuracy and product consistency.

[0017] 2. The present invention provides effective support for the wire coil during the unloading process through the wire support component, thereby avoiding the problem of loose wire bundles and ensuring the stability of the wire bundles.

[0018] 3. The present invention adopts a bidirectional screw-driven diameter expansion and contraction structure, which can flexibly adjust the encircling diameter of the wire support component. During winding, the diameter is expanded to tighten the wire, and during unloading, the diameter is reduced to loosen the wire roll, fundamentally solving the problems of difficult unloading and difficult removal of wire rolls by traditional winding rollers.

[0019] 4. The arc-shaped plate and dovetail guide rail in this invention are slidably detachable. During unloading, only the upper arc-shaped plate supports the wire coil. With the help of the electric push rod, the wire coil and support assembly can be smoothly slid out as a whole, avoiding swaying and collision damage to the winding roller and wire during hoisting, and greatly improving the safety of unloading.

[0020] 5. The baffle of the wire blocking unit in this invention can be vertically erected to limit the winding and prevent the wire from coming off during unloading; it can be laid flat and passed through the center hole of the wire roll during unloading, without interfering with the unloading of the wire roll, thus taking into account both the reliability of the limiting and the smoothness of unloading.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] like Figures 1-2As shown, the present invention provides a wire winding device for fixed length winding, including a drive mechanism 1 and a winding mechanism 2. The drive mechanism 1 includes a base 11, a support frame 12, a rotating shaft, a bearing seat, a reducer, and a drive motor 13. The support frame 12 is fixedly mounted on the base 11. The rotating shaft rotates through the support frame 12 via a bearing, and one end of the rotating shaft is fixedly connected to the winding mechanism 2. The bearing seat, reducer, and drive motor are all fixedly mounted on the base. The other end of the rotating shaft rotates through the bearing seat and is connected to the output end of the reducer. The output end of the drive motor 13 is connected to the input end of the reducer. The winding mechanism 2 includes a diameter expansion and contraction assembly 3 and a wire support assembly 4. The wire support assembly 4 is detachably and slidably mounted around the diameter expansion and contraction assembly 3.

[0026] Working principle: The wire support component 4 can support or detach the wire bundle as the diameter expansion and contraction component 3 expands or contracts. The wire support component 4 can be easily removed from the diameter expansion and contraction component 3 and bound to an external hook. Then, the wire bundle is slid off the diameter expansion and contraction component 3 together with the wire bundle, avoiding the shaking caused by the hook. Then, the wire support component 4 is separated from the wire bundle.

[0027] like Figures 3-8 As shown, the diameter expansion and contraction assembly 3 includes a hollow roller shaft 31, a bidirectional screw 34 rotatably connected inside the hollow roller shaft 31, and a support plate 35. One end of the hollow roller shaft 31 is fixedly connected to one end of the rotating shaft. A threaded cylinder 36 is threadedly connected to the bidirectional screw 34. Two threaded cylinders 36 are provided and are respectively provided on two sections of the thread on the bidirectional screw 34. It also includes a connecting arm 37 rotatably connected between the threaded cylinder 36 and the support plate 35. The support plate 35 is arranged around the hollow roller shaft 31 at equal intervals. Each support plate 35 and the two threaded cylinders 36 are provided with a connecting arm 37. The hollow roller shaft 31 has an elongated opening 38 along its length for the connecting arm 37 to slide through. One end of the bidirectional screw 34 rotatably passes through the hollow roller shaft 31 and is fixedly connected to a rotating handle 39.

[0028] Working principle of diameter expansion and contraction component 3: By setting the diameter expansion and contraction component 3, the support plate 35 is controlled to move away from or closer to the hollow roller shaft 31. This not only changes the distance between the support plate 35 and the bidirectional screw 34, but also simultaneously changes the distance between the wire support component 4 and the bidirectional screw 34. Since the wire is wound on the wire support component 4, the size of the circle enclosed by the wire support component 4 can be changed, thereby achieving the fixing and loosening of the wire.

[0029] like Figures 3-10As shown, the diameter expansion and contraction assembly 3 also includes a connecting unit 33. The connecting units 33 are evenly spaced around the hollow roller shaft 31. The connecting unit 33 includes a mounting plate 331 and a dovetail guide rail 332. The mounting plate 331 is fixedly mounted on the circumferential wall at both ends of the hollow roller shaft 31. Symmetrically distributed tension members 333 are fixedly mounted on the mounting plate 331. The bottom of the dovetail guide rail 332 is fixedly connected to the tension members 333 at both ends of the hollow roller shaft 31. The length direction of the dovetail guide rail 332 is parallel to the axis of the hollow roller shaft 31 and is symmetrically located on the side of the support plate 35 away from the hollow roller shaft 31.

[0030] like Figures 3-10 As shown, the tension member 333 includes a fixed cylinder 3131, a connecting rod 3132, a sliding block 3133, and a spring 3134. The fixed cylinder 3131 is fixedly mounted on the mounting plate 331. The sliding block 3133 is slidably mounted inside the fixed cylinder 3131. The bottom end of the connecting rod 3132 is fixedly connected to the sliding block 3133. The top end of the connecting rod 3132 slides through the top of the fixed cylinder 3131 and is fixedly connected to the bottom of the dovetail guide rail 332. The spring 3134 is slidably sleeved on the connecting rod 3132 and abuts against the top wall of the sliding block 3133 and the fixed cylinder 3131.

[0031] like Figure 3 , Figure 4 , Figures 11-14 As shown, the wire support assembly 4 includes an arc plate 41 and a wire blocking unit 42. The axis of the arc plate 41 coincides with the axis of the hollow roller shaft 31. The inner wall of the arc plate 41 facing the hollow roller shaft 31 is provided with a dovetail groove 43 that slides with the dovetail guide rail 332. The wire blocking unit 42 is distributed at both ends of the arc plate 41 on the side away from the hollow roller shaft 31 and is located between the two sets of dovetail grooves 43.

[0032] The working principle of the connecting unit 33 and the wire support assembly 4: The wire support assembly 4 is slidably connected through the connecting unit 33. The sliding cooperation between the dovetail groove 43 and the dovetail guide rail 332 facilitates the installation and removal of the wire support assembly 4 on the connecting unit 33, thereby facilitating the subsequent removal of the wire bundle.

[0033] like Figure 3 , Figure 4 , Figures 11-14As shown, the wire blocking unit 42 includes a baffle 421, a sliding rod 422, a second spring 423, and a limiting plate 424. The sliding rod 422 slides vertically through the arc-shaped plate 41. Four sets of locking rods 425 are fixedly provided at the bottom of the baffle 421. Fixed blocks 426 are fixed between the locking rods 425. The top of the sliding rod 422 is rotatably positioned between the fixed blocks 426 via a rotating shaft. The baffle 421 rotates along the length of the arc-shaped plate 41. The limiting plate 424 is fixedly provided at one end of the sliding rod 422 near the hollow roller shaft 31. The second spring 423 is slidably sleeved on the sliding rod 422 and abuts against the limiting plate 424 and the arc-shaped plate 41. A slot 427 is provided on the side wall of the arc-shaped plate 41 facing away from the hollow roller shaft 31. The bottom end of the locking rod 425 is engaged with the slot 427.

[0034] Working principle of wire blocking unit 42: The wire blocking unit 42 can limit the wound wire on the arc plate 41 to prevent wire unwinding. During winding, the baffle 421 is perpendicular to the arc plate 41. When it is necessary to place the baffle 421 horizontally, that is, horizontally with the arc plate 41, first pull the baffle 421 away from the arc plate 41. At this time, the sliding rod 422 and the limiting plate 424 move together with the baffle 421, and the spring 423... The baffle 421 is compressed until the locking rod 425 is moved out of the locking slot 427. Then the baffle 421 is rotated to a horizontal position and then the baffle 421 is released. At this time, under the pull of the second spring 423, the baffle 421 will be horizontally attached to the arc plate 41. At this time, the horizontal laying operation of the baffle 421 is completed. After the baffle 421 is laid horizontally, the arc plate 41 moves closer to the hollow roller shaft 31, which makes it easier to detach the wire bundle from the arc plate 41. The laid-down baffle 421 will pass through the center hole of the wire bundle.

[0035] like Figures 3-14 As shown, the diameter expansion and contraction assembly 3 also includes a rod 310, which is fixedly mounted on the side wall of the support plate 35 away from the hollow roller shaft 31. The bottom wall of the dovetail groove 43 is provided with a hole 44 for inserting the other end of the rod 310, and the dovetail guide rail 332 is provided with a round hole 334 for the rod 310 to slide through.

[0036] With the cooperation of the tension member 333 and the insertion rod 310, the spring 3134 is always in a compressed state. Using the rebound force of the spring 3134, the sliding block 3133 and the connecting rod 3132 are pulled to move towards the hollow roller shaft 31. This allows the arc plate 41 to fit well with the insertion rod 310, so that the arc plate 41 moves with the insertion rod 310, thus facilitating the adjustment of the distance between the arc plate 41 and the hollow roller shaft 31.

[0037] like Figures 3-14As shown, the diameter expansion and contraction assembly 3 also includes a limiting unit 32. The limiting unit 32 is arranged around the hollow roller shaft 31 at equal intervals. The limiting unit 32 includes a support screw 321 and a nut block 322. The support plate 35 has a clearance opening 311 for the support screw 321 to move through. The nut block 322 is fixed in the middle of the elongated opening 38. The support screw 321 is threaded through the nut block 322, and one end of it extends into the hollow roller shaft 31. The other end moves through the clearance opening 311 and contacts the inner wall of the arc plate 41 facing the hollow roller shaft 31.

[0038] like Figures 1-2 As shown, the drive mechanism 1 also includes an electric push rod 14, which is fixedly mounted on the top of the support frame 12, and its output end is fixedly provided with a push plate 15, which is horizontally located on one side of the baffle 421.

[0039] By using the limiting unit 32, and utilizing the contact between the support screw 321 and the arc plate 41, when the arc plate 41 moves closer to the hollow roller shaft 31, it facilitates keeping one set of arc plates 41 (the uppermost arc plate 41) in place, making it easier to remove the uppermost arc plate 41 along with the wire bundle later. In use, when the support plate 35 moves closer to the hollow roller shaft 31, the insertion rod 310 moves out of the insertion hole 44 on the bottom wall of the dovetail groove 43, thereby releasing the sliding restriction between the dovetail groove 43 and the dovetail guide rail 332. When the support plate 35 moves closer to the hollow roller shaft 31, the distance between the arc plate 41 and the bidirectional screw 34 decreases. Since the arc plate 41 in contact with the support screw 321 is exactly located at... Therefore, the uppermost arc plate 41 will not approach the hollow roller shaft 31 nor separate from the wire bundle. Other arc plates 41 approach the hollow roller shaft 31 and gradually separate from the wire bundle until they contact the corresponding support screw 321. Then, the rotation of the handle 39 stops. The clearance opening 311 allows the support screw 321 to pass through the support plate 35. At this time, only the uppermost arc plate 41 supports the wire bundle. The electric push rod 14 is activated, which drives the push plate 15 to move. The push plate 15 pushes the baffle 421 on one side to move, thereby causing the arc plate 41 to slide on the dovetail guide rail 332, so that the uppermost arc plate 41 is separated from the dovetail guide rail 332 and thus from the entire winding mechanism 2.

[0040] like Figure 11 As shown, a binding port 428 is provided at the top of the baffle 421. The binding port 428 is located at one end of the baffle 421, which facilitates the threading of the wire connected to the hook, and makes it convenient to subsequently bundle and lift the baffle 421, the arc plate 41 and the wire.

[0041] In practical use, the adjustment is as follows: First, rotate the handle 39 to drive the bidirectional screw 34 to rotate. When the handle controls the bidirectional screw 34 to rotate forward, the bidirectional screw 34 will cause the two threaded cylinders 36 to separate from each other, and the included angle between the connecting arm 37 and the bidirectional screw 34 will decrease. The connecting arm 37 will then drive the support plate 35 to move closer to the bidirectional screw 34. Conversely, when the handle controls the bidirectional screw 34 to rotate in reverse, the support plate 35 will be controlled to move away from the bidirectional screw 34. When the support plate 35 moves away from the bidirectional screw 34, the insert rod 310 can drive the arc plate 41 to move away from the bidirectional screw 34. Since the dovetail guide rail 332 is slidably connected to the dovetail groove 43 on the arc plate 41, the arc plate 41 drives the dovetail guide rail 332 to move synchronously. The dovetail guide rail 332 drives the connecting rod 3132 and the sliding block 3133 to move synchronously. At this time, the spring 3134 is compressed. Conversely, when the support plate 35 moves closer to the bidirectional screw 34, the spring force of the spring 3134 causes the connecting rod 3132, sliding block 3133, dovetail guide rail 332, and arc plate 41 to also move closer to the bidirectional screw 34. Therefore, by rotating the handle 39, not only can the distance between the support plate 35 and the bidirectional screw 34 be changed, but the distance between the arc plate 41 and the bidirectional screw 34 can also be changed simultaneously. Since the wire is wound on the arc plate 41, the diameter of the circle enclosed by the arc plate 41 can be changed, thereby achieving the fixing and loosening of the wire. In addition, after adjusting the position of the arc plate 41, it is also necessary to adjust the length of the support screw 321 extending from the elongated opening 38. Moreover, it is only necessary to adjust one set of support screws 321 to contact one set of arc plates 41, while the other support screws 321 have a certain gap distance from the corresponding arc plates 41.

[0042] Winding and Unloading: To achieve accurate measurement of the number of wire winding turns, a photoelectric sensor 16 is installed on the base 11. The device also includes a controller, which is electrically connected to the photoelectric sensor 16, the drive motor 13, and the electric push rod 14. The photoelectric sensor 16's detection end is aligned with the baffle 421 to detect the rotation position of the baffle 421 and output a detection signal to the controller. The drive motor 13 provides winding power, and the electric push rod 14 is used for unloading and pushing out the wire. After adjusting the distance between the arc plate 41 and the bidirectional screw 34, the controller starts the drive motor 13, which drives the hollow roller shaft 31 to rotate, winding the wire. The four baffles 421 at one end of the winding mechanism 2 rotate alternately to the front of the photoelectric sensor 16. Each time the photoelectric sensor 16 senses a turn, it outputs a detection signal to the controller. Every four senses correspond to the winding of the wire. One turn; the controller calculates the number of wire winding turns in real time by counting the number of detection signals to achieve fixed-length wire winding; the controller has a preset early deceleration threshold. When the cumulative number of detection signals reaches the early deceleration threshold, the controller controls the drive motor 13 to decelerate to counteract rotational inertia and avoid overshoot during shutdown; when the cumulative number of detection signals reaches the preset total number, the controller controls the drive motor 13 to stop; after winding is completed, the drive motor 13 stops. At this time, two sets of baffles 421 face upwards, and the arc plate 41 that contacts the support screw 321 is exactly at the top (the number of wire winding turns set by the controller can determine which arc plate 41 faces upwards). Then, a wire is inserted into the binding port 428 on the baffle 421 facing upwards, and the two sets of baffles 421 at the top are bound together with the wire. Then, the wire is hooked by the hook of the external lifting device.Simultaneously, rotate all the baffles 421 except the upper baffle 421 to be parallel to the arc plate 41 (the specific operation has been described above). Then rotate the handle 39, and all the support plates 35 will move closer to the hollow roller shaft 31, causing the insertion rod 310 to move out of the insertion hole 44 on the bottom wall of the dovetail groove 43. This releases the sliding restriction between the dovetail groove 43 and the dovetail guide rail 332. When the support plates 35 move closer to the hollow roller shaft 31, the distance between the arc plate 41 and the bidirectional screw 34 decreases. Since the arc plate 41 in contact with the support screw 321 is located at the top, the arc plate 41 at the top will not move closer to the hollow roller shaft 31 nor separate from the wire bundle. The other arc plates 41 move closer to the hollow roller shaft 31 and separate from the wire bundle until they contact the corresponding support screw 321, at which point the rotation stops. At this point, only the uppermost arc-shaped plate 41 supports the wire bundle. The controller activates the electric push rod 14, which moves the push plate 15. The push plate 15 pushes the side baffle 421 to move, which in turn moves the arc-shaped plate 41 to slide on the dovetail guide rail 332. This causes the uppermost arc-shaped plate 41 to detach from the dovetail guide rail 332 and thus from the entire winding mechanism 2. Since the wire bundle is hooked onto the baffle 421 by the hook of the external lifting device, it can prevent the wire bundle from being squeezed and contacted by the winding mechanism 2 due to gravity, thus avoiding obstruction of the removal of the wire bundle. At the same time, the arc-shaped plate 41 slides away from the dovetail guide rail 332 and thus from the entire winding mechanism 2, preventing the wire bundle from being suspended in the air and swaying. This also prevents the wire bundle from colliding with the winding mechanism 2 when it sways, thus avoiding damage to the winding mechanism 2. After the hook lifts the wire bundle to the desired position, the wire bundle is exposed as it detaches from the winding mechanism 2. This allows for easy bundling and securing of the wire bundle. Then, the wire on the baffle 421 is released, and the baffle 421 is rotated to be horizontal with the arc plate 41, facilitating the removal of the arc plate 41 from the wire bundle. After removing the arc plate 41, the baffle 421 is rotated to be perpendicular to the arc plate 41. The arc plate 41 is then re-slidably inserted into the dovetail guide rail 332, aligning the insertion hole 44 on the bottom wall of the dovetail groove 43 with the round hole 3 of the dovetail guide rail 332. 34 Alignment; One end of the dovetail groove 43 is provided with a positioning block 429. When the arc plate 41 slides into one end of the dovetail guide rail 332, the dovetail guide rail 332 will no longer move after contacting the positioning block 429. At this time, the insertion hole 44 on the bottom wall of the dovetail groove 43 is exactly aligned with the round hole 334 of the dovetail guide rail 332. Then rotate the rotating handle 39 to move the support plate 35 away from the hollow roller shaft 31, so that the insertion rod 310 is reinserted into the round hole 334 and the insertion hole 44, and the dovetail guide rail 332 is again limited in the dovetail groove 43 to prevent the dovetail guide rail 332 from shifting when winding the wire.
