Description

Technical Field

[0001] The present application relates to the technical field of wire and cable production, and in particular to a wire and cable preparation production line and manufacturing process. Background Art

[0002] With the continuous development of social economy and the increasing level of science and technology, my country's urbanization construction is also ongoing. Wires and cables have multiple functions such as controlling installation, connecting equipment and transmitting electricity. Therefore, they play an important role in urbanization construction and industry.

[0003] At present, in the wire and cable industry, traditional production methods still occupy a dominant position. The traditional production method divides the wire and cable production line into independent operation processes such as extrusion, cabling and coating, and adopts a decentralized production method. Through a large amount of manual intervention and manual real-time monitoring, each process is completed independently in sequence to meet the diversified needs of small batches.

[0004] Regarding the above-mentioned related technologies, due to the traditional decentralized production method in the existing technology, relevant personnel are required to transport each wire and cable in the current process to the construction site of the next process after completing the processing before starting the next production process. Therefore, when large-scale production of wires and cables is required, a large amount of manpower and material resources are required, which leads to a reduction in the production efficiency of wires and cables, so it needs to be improved. Summary of the Invention

[0005] In order to improve the production efficiency of wires and cables, the present application provides a wire and cable preparation production line and manufacturing process.

The raw material supply device includes a supply body and a pay-off roller, the pay-off roller is rotatably connected to the supply body, and the pay-off roller is provided with a wire drum containing raw material wire. The transmission system is used to transfer the raw material wire on the pay-off roller to the extrusion molding device, the cooling and shaping device, and the winding device in sequence. The extrusion molding device is used to coat an insulating layer on the raw material wire, the cooling and shaping device is used to cool the raw material wire coated with the insulating layer, and the winding device is used to wind the prepared raw material wire.

[0008] By adopting the above technical solution, compared with the existing technology, by adopting the traditional decentralized method, the relevant personnel have to transport each wire and cable to the construction site of the next process after completing the processing of each wire and cable in the current process, thereby starting the next production process, which leads to a decrease in production efficiency; the present application sets up a wire and cable preparation production line, so that the raw material line can be driven by the transmission system and transported to the extrusion molding device, the cooling and shaping device and the winding device in sequence, and the winding device can wind up the coated and cooled raw material line, thereby realizing the automated production of wires and cables, thereby reducing the number of manual interventions, and eliminating the need for relevant personnel to transport each raw material line between the two processes, thereby improving the preparation and production efficiency of wires and cables, and at the same time reducing the probability of quality risks due to manual operation errors.

[0009] Preferably, the winding device includes a winding body, a winding roller, a shifting roller and an adjusting mechanism. The winding roller is rotatably connected to the winding body and is used to wind up the prepared raw material line. The adjusting mechanism includes an adjusting frame and an adjusting component. The adjusting frame is slidably connected to the winding body, and the sliding direction is the axial direction of the winding roller. The shifting roller is rotatably connected to the adjusting frame and is used to abut against the side wall of the raw material line. The adjusting component is used to drive the adjusting frame to slide.

[0010] By adopting the above technical solution, the transposition roller and the adjustment mechanism are set up, so that the adjustment component can drive the adjustment frame to slide, so that the adjustment frame drives the transposition roller to move together, and then the transposition roller drives the raw material line to deviate along the axial direction of the winding roller, thereby changing the position of the raw material line wound on the winding roller, so that the raw material line can be evenly wound on the winding roller, thereby improving the uniformity of the raw material line on the winding roller, replacing the manual operation of relevant personnel, facilitating the operation of relevant personnel, and improving the winding efficiency.

[0011] Preferably, the adjustment mechanism also includes a tensioning wheel, a sliding frame and a sliding assembly. The tensioning wheel is rotatably connected to the sliding frame and is used to abut against the side wall of the raw material line. The sliding frame is slidably connected to the winding body, and the sliding assembly is used to drive the sliding frame to slide.

[0012] By adopting the above technical solution, the setting of the tensioning wheel allows the sliding assembly to slide by driving the sliding frame when the adjusting frame drives the transposition roller to move, so that the sliding frame drives the tensioning wheel to move, thereby changing the tension of the raw material line on the tensioning wheel, and adjusting the length of the raw material line between the transposition roller and the tensioning wheel according to the position of the transposition roller, thereby effectively reducing the probability of the raw material line being overstretched or broken.

[0013] Preferably, the sliding assembly includes a rotating frame, a sleeve frame and a rotating member, the rotating frame is rotatably connected to the winding body, the sleeve frame is sleeved on the rotating frame and slidably connected to the rotating frame, the sleeve frame is rotatably connected to the sliding frame, and the rotating member is used to drive the rotating frame to rotate.

[0014] By adopting the above technical solution and the specific arrangement of the sliding assembly, the rotating member can drive the rotating frame to rotate, thereby causing the rotating frame to drive the sleeve frame to displace, thereby causing the sleeve frame to drive the adjusting frame to slide, thereby driving the adjusting frame to slide. During this process, the sleeve frame slides relative to the rotating frame and rotates relative to the adjusting frame to adapt to the sliding of the adjusting frame, thereby ensuring the stability of the transmission between the rotating frame, the sleeve frame and the adjusting frame.

[0015] Preferably, the adjustment mechanism also includes a guide wheel, an additional wheel and an additional frame, and the sliding assembly also includes a linkage. The guide wheel is rotatably connected to the winding body, the additional frame is slidably connected to the winding body, the additional wheel is rotatably connected to the additional frame, and the guide wheel and the additional wheel are both used to abut against the side wall of the raw material line. The rotating frame drives the additional frame to slide through the linkage.

[0016] By adopting the above technical solution, the additional wheels and the additional frame are arranged so that when the rotating frame rotates, the additional frame can be driven to slide through the linkage member, so that the additional frame drives the additional wheels to move together, thereby changing the tension between the additional wheels and the tensioning wheel, and adjusting the length of the raw material line between the additional wheels and the tensioning wheel, further reducing the probability of excessive stretching or breakage of the raw material line, and at the same time realizing the linkage between the additional frame and the rotating frame, which is convenient for the operation of relevant personnel.

[0017] Preferably, the linkage member includes a linkage frame, the middle part of the rotating frame is rotatably connected to the winding body, the linkage frame is sleeved on one end of the rotating frame away from the sleeve frame, and is slidably connected to the rotating frame and rotatably connected to the additional frame.

[0018] By adopting the above technical solution and setting the linkage frame, the rotating frame can drive the linkage frame to move during the rotation process, thereby causing the linkage frame to drive the additional frame to slide, and making the sliding directions of the additional frame and the adjustment frame opposite, thereby realizing the sliding drive of the additional frame and the linkage between the additional frame and the adjustment frame, effectively saving the active device for driving the additional frame to slide, and also facilitating the operation of relevant personnel.

[0019] Preferably, a control mechanism is also provided on the winding machine body, and the control mechanism includes a detection part and a control part. The detection part and the rotating part are both controlled by the control part. The detection part is used to detect the tension of the raw material line on the tensioning wheel, and the control part is used to control the operation of the rotating part based on the tension detected by the detection part.

[0020] By adopting the above technical solution, the control mechanism is set up so that the detection part can detect the tension of the raw material line on the tensioning wheel, so that the control part can control the speed and angle of the rotating frame driven by the rotating part according to the tension of the raw material line, thereby realizing the control of the sliding of the adjustment frame, reducing the probability of the raw material line on the tensioning wheel being stretched or broken, and at the same time ensuring the uniformity of the winding of the raw material line.

[0021] Preferably, the number of the transposition rollers is set to two, and the two transposition rollers are respectively located on both sides of the raw material line. The end of each transposition roller is rotatably connected to a movable frame, and each movable frame is slidably connected to the adjustment frame. The adjustment frame is also provided with a drive assembly, and the drive assembly is used to drive each movable frame to slide.

[0022] By adopting the above technical solution, the transposition rollers and the drive assembly are arranged so that when the adjustment frame moves back and forth, the side walls of the raw material line can be against both transposition rollers, thereby ensuring the stability of the transposition rollers when driving the raw material line. At the same time, the presence of the drive assembly enables the movable frame to drive the transposition rollers to move, thereby changing the distance between the two transposition rollers, so that the transposition rollers can fully offset the raw material lines of different specifications and thicknesses.

[0023] Preferably, a lower pressure frame is also provided on the adjusting frame, which is lower than the winding roller and has a bottom end used to abut against the side wall of the raw material line. The lower pressure frame is slidably connected to the adjusting frame, and the sliding direction is the height direction of the adjusting frame. The driving assembly includes a driving member and two driving frames, the driving member is used to drive the lower pressure frame to slide, and the driving frame corresponds to the moving frame, and one end of each driving frame is rotatably connected to the corresponding moving frame, and the other end is rotatably connected to the lower pressure frame.

[0024] By adopting the above technical solution, the setting of the lower pressure frame and the linkage assembly enables the lower pressure frame to counteract the raw material line to ensure the tension of the raw material line wound on the winding roller, thereby ensuring the effect of the raw material line winding on the winding roller. At the same time, the driving member can drive the lower pressure frame to move, so that the lower pressure frame drives each mobile frame to be displaced through the driving frame, thereby realizing the driving of each mobile frame, realizing the linkage between the lower pressure frame and the mobile frame, and effectively facilitating the operation of relevant personnel.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-7 This application is described in further detail.

[0044] Example 1:

[0045] Example 1 of the present application discloses a production line for preparing electric wires and cables. Figure 1 and Figure 2 The wire and cable production line includes a raw material supply device 1, a transmission system 2, an extrusion molding device 3, a cooling and shaping device 4, and a winding device 5. The raw material supply device 1 includes a supply body 11 and a pay-off roller 12, which is rotatably connected to the supply body 11 and is provided with a raw material wire. The transmission system 2 is used to sequentially transfer the raw material wire on the pay-off roller 12 to the extrusion molding device 3, the cooling and shaping device 4, and the winding device 5. The extrusion molding device 3 is used to coat a layer of insulation on the raw material wire, the cooling and shaping device 4 is used to cool the raw material wire coated with the insulation layer, and the winding device 5 is used to wind the prepared raw material wire.

[0046] Reference Figure 2 The supply body 11 is placed on the ground, the axis of the pay-off roller 12 is arranged horizontally, and the pay-off roller 12 is rotatably connected to the supply body 11 via a bearing. The pay-off roller 12 is also provided with a wire drum containing the raw material wire, which is fixedly mounted on the pay-off roller 12. In the embodiment of the present application, the supply body 11 is also provided with a reduction motor, which is used to drive the pay-off roller 12 to rotate, thereby realizing the pay-off operation of the raw material wire.

[0047] Reference Figure 1 In this embodiment of the present application, the transmission system 2 may include a tractor and several conveyor stands. The tractor is used to pull the raw material line, thereby smoothly conveying the raw material line. The several conveyor stands are arranged between the extrusion molding device 3, the cooling and shaping device 4, and the winding device 5. Each stand may be provided with rollers to fully guide the raw material line. In this embodiment of the present application, rollers may also be provided on the extrusion molding device 3, the cooling and shaping device 4, and the winding device 5 to fully guide and support the raw material line.

[0048] Reference Figure 1 and Figure 3 The extrusion molding device 3 is placed on the ground and is used to coat the surface of the raw material wire being transported into it with an insulating layer to achieve insulation. In this embodiment of the application, the extrusion molding device 3 is also equipped with a temperature control structure to enable personnel to adjust the operating temperature curve of the extrusion molding device 3 to ensure the temperature of the rubber material. This extrusion molding device 3 is prior art and will not be described in detail here.

[0049] Reference Figure 1 and Figure 4The cooling and shaping device 4 is located on the side of the extrusion molding device 3 away from the supply body 11. The cooling and shaping device 4 includes a cooling body 41, a cooling trough 42, and a cooling pipe 43. The cooling trough 42 is fixedly mounted on the side wall of the cooling body 41. The top of the cooling trough 42 is provided with a water trough 421. The cooling trough 42 has holes at both ends along its length for the raw material line to pass through.

[0050] Reference Figure 4 Several cooling pipes 43 are provided, with one end of each located within the cooling body 41 and connected to the cooling water source within the cooling body 41. The other end is located directly above the water tank 421 and is bent downward. This allows the water in the cooling pipe 43 to fall into the water tank 421, where it comes into contact with the raw material wire within the water tank 421, continuously cooling the raw material wire. This ensures that the raw material wire surface is evenly cooled, thereby solidifying and forming a stable insulation layer structure. This ensures that the insulation layer has stable physical properties such as compressive and tensile resistance. A solenoid valve is also provided on the cooling pipe 43 to control the water flowing out of the cooling pipe 43.

[0051] Reference Figure 4 In the embodiment of the present application, a sponge for wiping the raw material line is also provided on the cooling and shaping device 4 to wipe the raw material line dry after cooling. In the implementation of the present application, a plurality of drain pipes are also provided at the bottom of the cooling tank body 42, and the drain pipes are used to drain the water in the water tank 421.

[0052] Reference Figure 1 The winding device 5 is located on the side of the cooling and shaping device 4 away from the extrusion molding device 3. The winding device 5 includes a winding body 51 and a winding roller 52. One end of the winding roller 52 is rotatably connected to the winding body 51 via a bearing. The other end of the winding roller 52 is provided with a winding drum, so that the prepared raw material wire is wound on the drum. The drum is fixedly mounted on the winding roller 52. In the embodiment of the present application, the winding body 51 is also provided with a reduction motor for driving the winding roller 52 to rotate, thereby driving the winding roller 52.

[0053] The implementation principle of a wire and cable preparation production line in Example 1 of the present application is as follows: when in use, the pay-off roller 12 rotates, so that the wire drum on the pay-off roller 12 pays off the raw wire. In the process of the wire drum on the pay-off roller 12 continuously paying off the raw wire, the raw wire passes through the extrusion molding device 3, so that the extrusion molding device 3 coats a layer of insulation on the raw wire. After the coating is completed, the transmission system 2 continues to transport the coated raw wire to the water trough 421 of the cooling trough body 42, and allows the water flowing out of the cooling pipe 43 to contact the raw wire, thereby cooling the insulation layer coated on the raw wire. After cooling is completed, the raw wire is wound up by the wire drum on the winding roller 52, completing the preparation and production of the wires and cables.

[0054] Example 1 of the present application also provides a manufacturing process for a wire and cable production line, comprising the following steps:

[0055] S1, preheating extrusion molding device: before production, first pass the raw material line into the machine mouth of the preheating extrusion molding device 3 for preheating and standby;

[0056] S2. Insulation coating: The extrusion molding device 3 is opened, and the pay-off roller 12 is continuously driven to drive the wire reel to pay off the raw wire. The raw wire is driven by the transmission system 2 and transported to the extrusion molding device 3. The extrusion molding device 3 coats an insulation layer on the raw wire.

[0057] S3. Cooling the insulation layer: The conveying system 2 transports the coated raw material wire to the water tank 421 of the cooling tank body 42. Water from the cooling pipe 43 contacts the raw material wire, cooling the insulation layer coated on the raw material wire, thereby cooling and solidifying the insulation layer to form a stable structure.

[0058] S4. Winding the raw material line: The transmission system 2 transports the cooled raw material line to the wire drum on the winding roller 52, and then the winding roller 52 drives the wire drum to rotate to continuously wind the raw material line.

[0059] Example 2:

[0060] The difference between Example 2 of the present application and Example 1 is that: Figure 4 and Figure 5 The winding device 5 also includes a transposition roller 53 and an adjustment mechanism 54. The adjustment mechanism 54 includes an adjustment frame 541 and an adjustment component 542. The adjustment frame 541 is slidably connected to the winding body 51 through a slide rail, and the sliding direction is parallel to the axial direction of the winding roller 52. The adjustment frame 541 is located on the side of the winding tube in the opposite direction of the raw material line conveying direction.

[0061] Reference Figure 4 and Figure 5 The adjustment assembly 542 includes an adjustment motor 5421 and an adjustment screw 5422. The adjustment motor 5421 is fixedly installed in the winding body 51, and the axial direction of the output shaft is the same as the sliding direction of the adjustment frame 541. The output shaft of the adjustment motor 5421 is fixedly connected to one end of the adjustment screw 5422 through a coupling to drive the adjustment screw 5422 to rotate. Both ends of the adjustment screw 5422 are rotatably connected to the winding body 51 through bearings. One end of the adjustment screw 5422 passes through the adjustment frame 541 and is threadedly connected to the adjustment frame 541, so that the adjustment frame 541 is driven to slide back and forth through its own rotation.

[0062] Reference Figure 5 and Figure 6The adjustment frame 541 is also provided with a movable frame 55, a lower pressure frame 56 and a drive assembly 57. The number of movable frames 55 is set to two, and each movable frame 55 is slidably connected to the adjustment frame 541 via a slide rail. The sliding direction of each movable frame 55 is set to the axial direction of the winding roller 52, and is respectively located on opposite sides of the raw material line. The number of transposition rollers 53 is set to two, and is arranged in a one-to-one correspondence with the movable frame 55. Each transposition roller 53 is arranged vertically, and both ends of each transposition roller 53 are rotatably connected to the corresponding movable frame 55 through bearings, and the side walls of each transposition roller 53 are against the side walls of the raw material line.

[0063] Reference Figure 5 and Figure 6 The lower pressure frame 56 is located on the side of the adjustment frame 541 near the winding roller 52. The bottom end of the lower pressure frame 56 extends downward and is slidably connected to the inner wall of the adjustment frame 541, and the sliding direction is vertical. The lower pressure frame 56 is also provided with a lower pressure roller 561. The axis of the lower pressure roller 561 is parallel to the axis of the winding roller 52 and is located on the lower side of the winding roller 52. Both ends of the lower pressure roller 561 are rotatably connected to the lower pressure frame 56 through bearings. The bottom end of the lower pressure roller 561 abuts against the top side wall of the raw material line to maintain the tension of the raw material line between the winding roller 52 reel and the lower pressure roller 561.

[0064] Reference Figure 5 and Figure 6 The driving component 57 includes a driving member 571 and two driving frames 572. In the embodiment of the present application, the driving member 571 is configured as a cylinder, which is fixedly mounted on the adjustment frame 541, and the piston rod of the cylinder is vertically upwardly arranged and fixedly connected to the lower pressure frame 56.

[0065] Reference Figure 5 and Figure 6 The driving frames 572 are arranged in a one-to-one correspondence with the mobile frames 55 and are respectively located on both sides of the lower pressing frame 56 along the sliding direction of the mobile frame 55. Each driving frame 572 is rotatably connected to the lower pressing frame 56 through a pin shaft, and the other end is tilted downward and rotatably connected to the corresponding mobile frame 55 through a pin shaft.

[0066] Reference Figure 5 and Figure 6 Initially, the stock line is below the lower pressing roller 561 and does not abut against it. At this point, the transposition rollers 53 are located on either side of the stock line and do not abut against the lower pressing roller 561. As the driver 571 drives the lower pressing frame 56 downward, the bottom end of the lower pressing roller 561 gradually abuts against the stock line. During this process, the lower pressing frame 56, via its two driving frames 572, causes each of the mobile frames 55 to slide, bringing the two mobile frames 55 closer together, thereby causing both transposition rollers 53 to abut against the stock line.

[0067] Reference Figure 4 、 Figure 5 and Figure 7 The adjustment mechanism 54 further includes a guide wheel 543, an additional wheel 544, an additional frame 545, a tensioning wheel 546, a sliding frame 547, and a sliding assembly 548. The guide wheel 543 is located on the side of the winding body 51 away from the winding roller 52 and is rotatably connected to the winding body 51 via a bearing and is vertically arranged. The additional frame 545 is located between the guide wheel 543 and the adjustment frame 541 and is slidably connected to the winding body 51 via a slide rail, with the sliding direction parallel to the axis of the winding roller 52. The bottom end of the additional wheel 544 is rotatably connected to the additional frame 545 via a bearing and is vertically arranged.

[0068] Reference Figure 4 、 Figure 5 and Figure 7 The sliding frame 547 is located between the additional frame 545 and the adjustment frame 541. It is slidably connected to the winding body 51 via a slide rail, and its sliding direction is parallel to the axis of the winding roller 52. In the initial state, the sliding frame 547 is located to one side of the winding roller 52 along its own axis. The tensioning pulley 546 is mounted on the sliding frame 547.

[0069] Reference Figure 4 、 Figure 5 and Figure 7 The sliding assembly 548 includes a rotating frame 5481, a sleeve frame 5482, a rotating member 5483, and a linkage member 5484. The rotating frame 5481 is pivotally connected to the winding body 51 via a pin at one end along its length, with the rotation axis disposed vertically. In this embodiment, the rotating member 5483 is configured as a servo motor, which is fixedly mounted within the winding body 51. The output shaft of the servo motor is disposed vertically upward and is pivotally connected to the middle portion of the rotating frame 5481 to drive the rotating frame 5481.

[0070] Reference Figure 5 and Figure 7 The sleeve frame 5482 is sleeved on one end of the rotating frame 5481 and is slidably connected to the rotating frame 5481. The sleeve frame 5482 is rotatably connected to the bottom end of the sliding frame 547 via a pin. The linkage member 5484 includes a linkage frame 54841. The linkage frame 54841 is sleeved on the end of the rotating frame 5481 away from the sleeve frame 5482 and is slidably connected to the rotating frame 5481. The linkage frame 54841 is rotatably connected to the bottom end of the additional frame 545 via a pin.

[0071] Reference Figure 5 and Figure 7When the rotating member 5483 drives the rotating frame 5481 to rotate, the rotating frame 5481 causes the sleeve frame 5482 and the linkage frame 54841 to slide, thereby causing the sleeve frame 5482 to cause the sliding frame 547 to slide, and the linkage frame 54841 to cause the additional frame 545 to slide, with the sliding directions of the additional frame 545 and the sliding frame 547 being opposite. During this process, the sleeve frame 5482 and the linkage frame 54841 both slide relative to the rotating frame 5481 to accommodate the sliding of the additional frame 545 and the sliding frame 547.

[0072] Reference Figure 5 and Figure 7 A displacement frame 58 is also mounted on the sliding frame 547. Displacement frame 58 is slidably connected to the top of the sliding frame 547 via a slide rail, and its sliding direction is the same as that of the sliding frame 547. The bottom end of the tensioning wheel 546 is rotatably connected to the displacement frame 58 via a pin, and the tensioning wheel 546 is positioned vertically. The material line passes through the guide wheel 543, the additional wheel 544, and the tensioning wheel 546, reaching between the two transposition rollers 53.

[0073] Reference Figure 4 and Figure 7 The winding body 51 is also provided with a control mechanism 6, which includes a detection member 61 and a control member 62. In the embodiment of the present application, the detection member 61 is configured as a pressure sensor, and the control member 62 is configured as a PLC controller. The pressure sensor is fixedly mounted on the sliding frame 547 and is located on the sliding path of the displacement frame 58.

[0074] Reference Figure 4 and Figure 7 The sliding frame 547 is also provided with a pressure spring 59, which is arranged between the detection member 61 and the displacement frame 58 and is sleeved on the top of the sliding frame 547. One end of the pressure spring 59 abuts against the detection member 61, and the other end abuts against the displacement frame 58, so that the pressure applied by the pressure spring 59 to the detection member 61 is in a continuous state.

[0075] Reference Figure 4 and Figure 7 The detection member 61 and the rotating member 5483 are both electrically connected to the control member 62. The detection member 61 is used to detect the pressure applied by the pressure spring 59, thereby reflecting the tension of the raw material thread on the tensioning wheel 546. The detection member 61 is used to feed back the detected pressure value to the control member 62. The control member 62 has a preset value stored in it. This preset value is the pressure value detected by the detection member 61 when the raw material thread on the tensioning wheel 546 is in a properly tensioned state.

[0076] Reference Figure 4 and Figure 7The control member 62 is used to receive the pressure value detected by the detection member 61 and compare the detected pressure value with a preset value. When the pressure value detected by the control member 62 is greater than the preset value, the control member 62 drives the output shaft of the rotating member 5483 to rotate forward, causing the sliding frame 547 to move closer to the additional frame 545. When the pressure value detected by the control member 62 is less than the preset value, the control member 62 drives the output shaft of the rotating member 5483 to rotate backward, causing the sliding frame 547 to move away from the additional frame 545, thereby ensuring the tension of the stock line on the tensioning wheel 546 and allowing the stock line to be retracted and extended to a certain extent to adapt to the position change of the adjustment frame 541.

[0077] Reference Figure 4 and Figure 5 In the embodiment of the present application, the reduction motor that drives the winding roller 52 to rotate is also electrically connected to the control component 62, so that the control component 62 can control the rotation speed of the winding roller 52, further ensuring that the tension of the raw material line is in an appropriate state.

[0078] The implementation principle of a wire and cable preparation production line in Example 2 of the present application is as follows: during winding, the adjustment component 542 drives the adjustment frame 541 to slide, so that the adjustment frame 541 drives the raw wire to be wound around different positions of the wire drum on the winding roller 52. During this process, the control component 62 controls the operation of the rotating component 5483 according to the pressure value detected by the detection component 61, so that the rotating component 5483 drives the rotating frame 5481 to rotate. During this process, the rotating frame 5481 drives the sleeve frame 5482 and the linkage frame 54841 to slide, so that the sleeve frame 5482 drives the sliding frame 547 to slide, and the linkage frame 54841 drives the additional frame 545 to slide, thereby adjusting the tension of the raw wire and retracting and releasing the raw wire to a certain extent to adapt to the position change of the adjustment frame 541.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
