Description

Technical Field

[0001] This utility model relates to the field of metal material production technology, and in particular to a metal wire rewinding and fixing fixture. Background Technology

[0002] Currently, in the field of metal wire processing, after the metal wire is processed, it is wound onto the traction wheel. The irregular winding on the traction wheel usually affects the sale of the metal wire. Therefore, it is necessary to rewind the metal wire onto another traction wheel. Traditional devices use limiting components to limit the metal wire, thereby arranging the metal wire on the next traction wheel in an orderly manner.

[0003] Related technology can be found in Chinese Patent No. CN214359480U, which discloses a rewinding device for metal wire production. The device includes a support base and a metal wire. A mounting base is symmetrically welded to the top of the support base, and the mounting base is rotatably connected to a rotating shaft. A winding roller is coaxially welded to the rotating shaft, and the metal wire is wound around the winding roller. Support columns are symmetrically welded to the support base, and a fixing plate is welded to the support columns. Several straight rods are welded to the bottom of the fixing plate, and each straight rod is slidably connected to a stop block. The stop block has a cavity inside, and a limit block is welded to the bottom of the straight rod. The limit block slides within the cavity and is welded to a spring. This invention, through the cooperation of the stop block and the spring, ensures that the metal wire remains tightly wound on the winding roller, making the metal wires wound on the winding roller more closely fitted and achieving a pressing effect on the metal wires wound on the winding roller.

[0004] Regarding the aforementioned technologies, during the rewinding process of metal wire, there is a mismatch between the wire feeding speed on the feed wheel and the winding speed on the rewinding wheel, which can lead to loose rewinding or wire breakage due to excessive tension, thus affecting the quality of metal wire winding. Utility Model Content

[0005] To improve the quality of metal wire winding, this application provides a metal wire rewinding fixing fixture.

[0006] This application provides a metal wire rewinding and fixing fixture, which adopts the following technical solution: A metal wire rewinding fixture includes a support plate. One end of the support plate is rotatably connected to a feed roller for supporting and unwinding the metal wire roll. A rewinding roller for winding the metal wire is located on the side of the support plate away from the feed roller. A mounting base is slidably connected to the support plate laterally, and a slide rail is fixedly provided to guide the movement of the mounting base. The rewinding roller is rotatably connected to the mounting base. A motor for driving the rewinding roller is fixedly connected to the mounting base. An elastic element is provided between the slide rail and the mounting base. In its natural state, the mounting base is located at the end of the slide rail away from the feed roller. In the working state of the rewinding roller, the mounting base is located in the middle position of the slide rail. At this time, the elastic element tends to push the mounting base away from the feed roller. A pulley is slidably connected to the support plate vertically. The pulley is located between the pay-off pulley and the rewinding pulley. The support plate is equipped with a drive component for moving the pulley. The pulley, pay-off pulley, and rewinding pulley are in different height planes. During the rewinding process, the wire rolls and connects with the pulley. The pulley applies a vertical thrust to the wire and tensions it. A pressure sensor is located at the end of the slide rail near the pay-off pulley and a pressure sensor is located at the end away from the pay-off pulley. Both pressure sensors are electrically connected to the drive component. When the rewinding pulley is in operation, when the mounting base approaches and contacts pressure sensor one, pressure sensor one is triggered, and the pulley is driven to descend via the drive component. When the mounting base approaches and contacts pressure sensor two, pressure sensor two is triggered, and the pulley is driven to rise via the drive component.

[0007] By adopting the above technical solution, under the support of the support plate, the motor drives the rewinding wheel to rotate, which pulls the metal wire. Simultaneously, the pay-off wheel rotates, and the rewinding wheel experiences a reaction force from the metal wire, tending to move closer to the pay-off wheel. The rewinding wheel drives the mounting base closer to the pay-off wheel, at which point the elastic element is compressed. When the reaction force of the metal wire and the elastic element reach equilibrium, the mounting base is in the middle position of the slide rail, and at this time, the height of the pulley is higher than that of the rewinding wheel and the pay-off wheel, supporting the metal wire and causing it to bend. When the pay-off speed of the pay-off wheel does not meet the winding speed of the rewinding wheel, the tension applied to the metal wire during the winding process of the rewinding wheel increases. At this time, the metal wire becomes taut, causing the rewinding wheel to... As the pulley moves along the slide rail towards pressure sensor one, and the mounting base contacts pressure sensor one, pressure sensor one controls the drive mechanism to operate. The drive mechanism drives the pulley to descend, thereby relaxing the tension on the wire, providing buffer space for the wire, and reducing the probability of wire breakage. When the speed of the pay-off pulley is greater than the winding speed of the rewinding pulley, the wire becomes slack, and the reaction force on the rewinding pulley decreases. The rewinding pulley moves along the slide rail towards pressure sensor two, and the mounting base contacts pressure sensor two. Pressure sensor two controls the drive mechanism to operate, causing the drive mechanism to drive pulley two to rise, applying an upward thrust to the wire, thus tightening the wire and reducing the probability of the wire detaching from the pulley. This also helps improve the quality of wire winding.

[0008] Optionally, the support plate is also equipped with two pressure rollers, both of which are located between the pay-off roller and the rewinding roller. A pulley is located between the two pressure rollers. The support plate is provided with mounting parts for connecting the pressure rollers. After the metal wire is wound around the pressure rollers, the pressure rollers apply a pushing force to the metal wire, and the direction of the pushing force of the pressure rollers on the metal wire is opposite to the direction of the pushing force of the pulleys on the metal wire, so that the metal wire remains taut.

[0009] By adopting the above technical solution, two pressure rollers simultaneously apply a thrust opposite to that of the pulley on both sides of the pulley, so that the metal wire is evenly tensioned, reducing the probability of the metal wire falling off the pulley and improving the stability of the metal wire during rewinding.

[0010] Optionally, the mounting component includes a fixing block, a fixing rod, an elastic element two, and a sliding plate. The fixing block is fixed on the support plate, the fixing rod passes through the fixing block axially and is threadedly connected to the fixing block, the fixing rod is placed parallel to the plane of the support plate, the sliding plate is sleeved on the outside of the fixing rod and is slidably connected to the fixing rod along the length direction of the fixing rod, the pressure roller is located on the inside of the sliding plate and is rotatably connected to the sliding plate, and the elastic element two is located between the sliding plate and the fixing block, used to push the sliding plate away from the fixing block.

[0011] By adopting the above technical solution, under the support of the fixed block, the distance between the sliding plate and the fixed block can be easily adjusted by rotating the fixed rod. The sliding plate supports and limits the pressure wheel. Under the action of the elastic element, the pressure wheel pushes the sliding plate up and down along the fixed rod according to the tension of the metal wire, thereby adjusting the thrust applied to the metal wire, which helps to reduce the probability of metal wire breakage and detachment.

[0012] Optionally, the driving component includes a second motor, a lifting block, a limiting rod, and a threaded rod. The second motor is fixedly connected to the support plate, the threaded rod is coaxially fixed to the output shaft of the second motor, two limiting rods are fixedly installed on the support plate in the vertical direction and are parallel to the threaded rod, the lifting block is located between the two limiting rods, the limiting rod passes through the lifting block and is slidably connected to the lifting block, the threaded rod passes through the lifting block and is threadedly connected to the lifting block, and a pulley is rotatably connected to one end of the lifting block.

[0013] By adopting the above technical solution, when pressure sensor one and pressure sensor two control motor two to work, motor two drives the threaded rod to rotate, the threaded rod drives the lifting platform to slide up and down along the limit rod, and the lifting platform drives the pulley to move up and down, so as to adjust the thrust applied by the pulley to the metal wire, which helps to reduce the probability of the metal wire breaking or falling off.

[0014] Optionally, a rolling shaft is rotatably connected to the side of the mounting base near the pay-off wheel. The rolling shaft is parallel to the rewinding wheel. A pulley assembly is provided between the motor and the rolling shaft. When the motor is working, it drives the rolling shaft to rotate through the pulley assembly. A movable ring is slidably connected to the mounting base along the length of the rolling shaft. A guide groove with the ends connected is opened on the outer side of the rolling shaft along the circumferential direction. A slider is fixedly connected to the movable ring. The slider is located in the guide groove and is slidably connected to the rolling shaft along the guide groove. Two vertical rods are arranged at the upper end of the movable ring. A metal wire passes through the two vertical rods and is close to the vertical rods.

[0015] By adopting the above technical solution, under the driving action of the pulley group, the motor drives the rewinding wheel to rotate and at the same time drives the rolling shaft to rotate. The rolling shaft limits the slider through the guide groove. When the rolling shaft rotates, the slider drives the moving ring to move back and forth along the rolling shaft. The metal wire passes through the middle of the two vertical rods at the upper end of the moving ring. Under the limiting action of the vertical rods, the metal wire is evenly wound along the axis of the rewinding wheel, which is beneficial to improving the rewinding quality of the metal wire.

[0016] Optionally, the support plate is fixedly connected to two circular plates, which are arranged vertically parallel to the support plate. The circular plates are located on the side of the rolling shaft near the wire feeding wheel. Two parallel clamping plates are slidably connected to the side of the two circular plates that are close to each other. The metal wire passes through the middle of the clamping plates. The two circular plates are rotatably connected to a bidirectional lead screw. The two clamping plates are located at the two ends of the bidirectional lead screw. The bidirectional lead screw passes through the clamping plates and is threadedly connected to the clamping plates. The support plate is rotatably connected to a baffle on the side of the pressure sensor two near the wire feeding wheel. When the rewinding wheel is in working condition, the baffle is located on the side of the mounting base near the pressure sensor two.

[0017] By adopting the above technical solution, the circular plate supports and limits the bidirectional lead screw. When the bidirectional lead screw is rotated, it drives the clamping plate to move along the limiting rod, so that the two clamping plates move closer or further apart. When the rewinding wheel is full of metal wire, the metal wire on the rewinding wheel needs to be removed and rewound onto the rewinding wheel. At this time, the metal wire is clamped by the cooperation of the two clamping plates so that the operator can cut the metal wire and replace the rewinding wheel. When it is time to cut the metal wire, the baffle is lowered to block the mounting seat and prevent the rewinding wheel from losing tension and hitting the pressure sensor when the metal wire is cut.

[0018] Optionally, a mounting plate is vertically rotatably connected to the side of the clamping plate near the rolling shaft, and a blade is fixedly connected to the end of the mounting plate away from the clamping plate. The blades on the two clamping plates are close to each other, and an elastic element three is provided between the clamping plate and the mounting plate. The elastic element three is used to push the blade away from the clamping plate.

[0019] By adopting the above technical solution, when the clamping plate clamps the metal wire, the operator rotates the blade through the mounting plate. The elastic element reduces the probability of the blade contacting the metal wire under natural conditions. By pressing the two mounting plates, the two blades are brought closer together, thereby cutting the metal wire so that it can be rewound around the outside of the rewinding wheel, which helps to improve the convenience of the rewinding operation of the metal wire.

[0020] Optionally, a flattening column is provided above the rewinding wheel, and a support block is slidably connected to the upper end of the mounting base along the vertical direction. The flattening column is located at the lower end of the support block and is rotatably connected to the support block. A damper is provided between the support block and the mounting base, and the damper is used to adjust the friction between the support block and the mounting base.

[0021] By adopting the above technical solution, the mounting base supports the flattening column through the support block, allowing the flattening column to move vertically. During the rewinding process, the flattening column contacts the metal wire and flattens the metal wire, which is beneficial for the metal wire to be arranged flat along the length of the rewinding wheel. When the thickness of the metal wire wound on the outer side of the rewinding wheel increases, the metal wire pushes the flattening column to move vertically, so that the height of the flattening column is automatically adjusted. The friction between the support block and the support plate is adjusted by the damper, which helps to reduce the probability of the flattening column shaking violently and improve the working stability of the flattening column.

[0022] Optionally, a protective box is installed on the support plate. The protective box is cylindrical and is fitted over the outside of the wire feeding reel. The protective box has an outlet along its length for the wire to pass through. The edge of the outlet is wrapped with a rubber strip. The protective box and the support plate are detachably connected for replacing the wire feeding reel.

[0023] By adopting the above technical solution, the wire feeding reel rotates inside the protective box to feed the wire. The rubber strip prevents the wire outlet from cutting the metal wire. When the metal wire breaks, the protective box limits the metal wire, reducing the probability of the metal wire flying and injuring people, which helps to improve the safety of the device. The protective box and the support plate are detachably connected so that the wire feeding reel can be replaced.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By adopting the above technical solution, under the support of the support plate, motor one drives the rewinding wheel to rotate, the rewinding wheel pulls the metal wire, and at the same time causes the pay-off wheel to rotate. The elastic element one keeps the rewinding wheel in a relatively stable state. When the pay-off speed of the pay-off wheel does not meet the winding speed of the rewinding wheel, the tension applied to the metal wire during the winding process of the rewinding wheel increases. At this time, the metal wire is taut, and the metal wire exerts a reaction force on the rewinding wheel, causing the rewinding wheel to move closer to the pressure sensor one along the slide rail. The mounting base contacts the pressure sensor one, and the pressure sensor controls the driving element through an electrical connection. The driving element drives the slide rail... As the first pulley descends, it provides a buffer space for the wire, reducing the probability of wire breakage. When the speed of the pay-off pulley is greater than the winding speed of the rewinding pulley, the tension on the wire during the winding process of the rewinding pulley decreases. At this time, the wire becomes slack, and the reaction force on the rewinding pulley from the wire decreases. The rewinding pulley moves closer to the second pressure sensor along the slide rail, and the mounting base contacts the second pressure sensor. The second pressure sensor controls the drive unit through an electrical connection. The drive unit drives the second pulley to rise, applying an upward thrust to the wire, which makes the wire taut and prevents the wire from detaching from the support plate, thus improving the quality of wire winding. 2. By adopting the above technical solution, two pressure rollers simultaneously apply a thrust opposite to the pulley on both sides of the pulley, so that the metal wire is evenly tensioned, reducing the metal wire from falling off the pulley, which is beneficial to improving the stability of the metal wire during rewinding. 3. By adopting the above technical solution, under the support of the fixed block, the distance between the sliding plate and the fixed block can be easily adjusted by rotating the fixed rod. The sliding plate supports and limits the pressure wheel. Under the action of the elastic element two, the pressure wheel pushes the sliding plate up and down along the fixed rod according to the tension of the metal wire, thereby adjusting the thrust applied to the metal wire, which helps to reduce the probability of metal wire breakage and detachment.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a metal wire rewinding and fixing fixture. Example

[0032] Reference Figure 1 and Figure 2 A wire rewinding fixing fixture includes a support plate 1, a rewinding wheel 7 on the support plate 1, and a mounting seat 8 between the rewinding wheel 7 and the support plate 1. A protrusion is fixedly provided on the side of the mounting seat 8 near the support plate 1. A slide rail 83 corresponding to the protrusion is fixedly connected to the support plate 1 along the direction from the wire feeding wheel 2 to the rewinding wheel 7. The slide rail 83 is horizontally arranged, and the protrusion is located inside the slide rail 83 and slidably connected to the slide rail 83. A support wheel is installed on the lower end face of the mounting seat 8, and a track parallel to the slide rail 83 is installed on the support plate 1. The support wheel is rotatably connected to the track along the length of the track to reduce the friction between the mounting seat 8 and the support plate 1, so that the mounting seat 8 slides laterally along the support plate 1.

[0033] Reference Figure 1 and Figure 2 A motor 84 is fixedly connected to the mounting base 8. The rewinding wheel 7 includes a rotating shaft and a take-up drum. The rotating shaft is rotatably connected to the mounting base 8. When the mounting base 8 moves, it drives the rotating shaft to move. The take-up drum is sleeved on the outside of the rotating shaft and rotates coaxially with the rotating shaft. The output shaft of the motor 84 is fixed coaxially with the rotating shaft. The take-up drum and the rotating shaft are detachably connected by bolts. When the motor 84 is working, it drives the rotating shaft to rotate. The rotating shaft drives the take-up drum to rotate. The metal wire is wound on the outside of the take-up drum. When the take-up drum rotates, it drives the metal wire to rewind.

[0034] Reference Figure 1 and Figure 2On the side of the support plate 1 away from the rewinding wheel 7, there is a wire feeding wheel 2. The wire feeding wheel 2 is rotatably connected to the support plate 1 and is used to wind the metal wire to be rewound. The traction wheel and the rewinding wheel 7 are located at the same horizontal height. The rewinding wheel 7 rotates under the drive of the motor 84 and pulls the metal wire to wind around its own circumference.

[0035] Reference Figure 1 and Figure 2 An elastic element 85, a spring, is provided between the slide rail 83 and the mounting base 8. One end of the spring is fixedly connected to the mounting base 8, and the other end is fixedly connected to the support plate 1. When the outer side of the rewinding wheel 7 is not wound with metal wire, the mounting base 8 is located at the end of the slide rail 83 away from the pay-off wheel 2. During the rewinding process, the rewinding wheel 7 is subjected to the reaction force of the metal wire, which pushes the mounting base 8 closer to the pay-off wheel 2. At this time, the spring is in a compressed state. When the spring force and the reaction force of the metal wire reach equilibrium, the mounting base 8 is located in the middle position of the slide rail 83.

[0036] Reference Figure 1 and Figure 3 A pulley 4 is provided between the wire feeding wheel 2 and the rewinding wheel 7. The pulley 4 has multiple limiting grooves along its outer circumference for limiting the wire. A driving component 41 is provided between the pulley 4 and the support plate 1. The driving component 41 includes a second motor 411, a threaded rod 412, limiting rods 413, and a lifting block 414. The pulley 4 is rotatably connected to the lifting block 414. The second motor 411 is fixedly connected to the support plate 1. Two limiting rods 413 are located on both sides of the pulley 4 and fixedly connected to the support plate 1. The two limiting rods 413 pass through… The threaded rod 412 passes through both sides of the lifting block 414 and is slidably connected to the lifting block 414. The threaded rod 412 is parallel to the limiting rod 413 and is set between the two limiting rods 413. The lifting block 414 is sleeved on the outside of the threaded rod 412 and threadedly connected to the threaded rod 412. One end of the threaded rod 412 is coaxially fixed with the output shaft of the second motor 411. When the second motor 411 is working, it drives the threaded rod 412 to rotate, so that the lifting block 414 moves vertically. The metal wire is wound around the pulley 4, and the pulley 4 keeps the metal wire in a taut state.

[0037] Reference Figure 2 and Figure 3 Slide rail 83 is close to the wire feeding wheel 2 (reference) Figure 1 A pressure sensor 86 is slidably connected vertically to one side of the rewinding wheel 7, and a pressure sensor 87 is slidably connected to the other side near the rewinding wheel 7. Both pressure sensors 86 and 87 are electrically connected to motor 411. When the rewinding wheel 2 (reference) Figure 1When the speed does not meet the speed of the rewinding wheel 7, the spring tends to push the mounting base 8 away from the pay-off wheel 2. The traction force of the rewinding wheel 7 on the wire increases, and the reaction force of the wire on the rewinding wheel 7 increases. The rewinding wheel 7 pushes the mounting base 8 closer to the pressure sensor 86. The mounting base 8 contacts the pressure sensor 86, triggering the pressure sensor 86 and generating an electrical signal that is fed back to the motor 411. After receiving the signal from the pressure sensor 86, the motor 411 starts and drives the lifting block 414 downward through the threaded rod 412, thereby relaxing the tension on the wire and preventing the wire from breaking.

[0038] Reference Figure 2 and Figure 3 When the pay-off reel 2 (reference) Figure 1 Speed ​​when the line feeder reel is 2 (reference) Figure 1 When the speed is faster than the speed of the rewinding wheel 7, the traction force of the rewinding wheel 7 on the metal wire decreases, and the reaction force of the metal wire on the rewinding wheel 7 decreases. The rewinding wheel 7 pushes the mounting base 8 closer to the pressure sensor 87. The mounting base 8 contacts the pressure sensor 87, which triggers the pressure sensor 87 and generates an electrical signal that is fed back to the motor 411. After receiving the signal from the pressure sensor 87, the motor 411 starts and drives the lifting block 414 to move upward through the threaded rod 412. The lifting block 414 moves upward, and the pulley 4 applies a pushing force to the metal wire, which makes the metal wire taut.

[0039] Reference Figure 1 and Figure 3 Two pressure rollers 3 are provided on both sides of the pulley 4. An installation component 31 is provided between the two pressure rollers 3 and the support plate 1. The installation component 31 includes a fixing block 312, a fixing rod 311, a sliding plate 313 and an elastic element 314. The fixing block 312 is installed on the support plate 1. One end of the fixing rod 311 is provided with an external thread, and the end of the fixing rod 311 with the external thread passes through the fixing block 312 and is threadedly connected to the fixing block 312. When the fixing rod 311 is rotated, the fixing rod 311 moves relative to the fixing block 312 along the axial direction.

[0040] Reference Figure 1 and Figure 3 The sliding plate 313 is sleeved on the side of the fixed rod 311 away from the fixed block 312. The sliding plate 313 is slidably connected to the fixed rod 311 along the length of the fixed rod 311. The pressure wheel 3 is located inside the sliding plate 313 and is rotatably connected to the sliding plate 313. The elastic element 314 is a spring. One end of the spring is fixedly connected to the fixed rod 311 and the other end is fixedly connected to the sliding plate 313. In the initial state, the spring has the tendency to push the sliding plate 313 away from the fixed block 312. The metal wire is wound around the pressure wheel 3 to reduce the probability of the metal wire falling off the pulley 4.

[0041] Reference Figure 2 and Figure 4 The mounting base 8 is rotatably connected to the rolling shaft 6 in front of the rewinding wheel 7. A pulley assembly is provided between the rolling shaft 6 and the mounting base 8. The pulley assembly includes a first pulley 67, a second pulley 71 and a belt 72. The first pulley 67 and the rolling shaft 6 are coaxially and fixedly connected. The second pulley 71 and the output shaft of the first motor 84 are coaxially and fixedly connected. The belt 72 is sleeved between the first pulley 67 and the second pulley 71. When the first motor 84 is working, it drives the second pulley 71 to rotate. The first pulley 67 is driven to rotate through the belt 72, and then the first pulley 67 drives the rolling shaft 6 to rotate.

[0042] refer to Figure 1 and Figure 4 Two guide grooves 61, connected end to end, are provided on the outer side of the rolling shaft 6. The guide grooves 61 are spirally arranged around the circumference of the rolling shaft 6. A movable ring 63 is provided on the outer side of the rolling shaft 6, which is sleeved on the outer side of the rolling shaft 6 and slidably connected to the rolling shaft 6. A slider 62 is provided inside the movable ring 63, which is located in the guide groove 61 and slidably connected to the guide groove 61. A support rod 65 is fixedly provided at the lower end of the movable ring 63. A sliding groove 66 is fixedly provided on the mounting plate 54 to accommodate the support rod 65. The support rod 65 is located in the sliding groove 66 and slidably connected to the sliding groove 66 along the length of the sliding groove 66, which helps to improve the stability of the movable ring 63. Under the limiting action of the guide groove 61, when the rolling shaft 6 rotates, the slider 62 drives the movable ring 63 to reciprocate along the length of the rolling shaft 6.

[0043] refer to Figure 1 and Figure 2 Two vertical rods 64 are fixed on the moving ring 63. The vertical rods 64 are set parallel to the limiting rod 413. The metal wire passes through the middle of the two vertical rods 64. When the moving ring 63 moves, it drives the vertical rods 64 to move, so that the two vertical rods 64 drive the metal wire to move back and forth along the axis of the rewinding wheel 7. Then, under the limiting action of the vertical rods 64, the metal wire is evenly arranged along the length of the rewinding wheel 7.

[0044] Reference 1 and Figure 4 A circular plate 5 is fixedly installed on the support plate 1. Two slide rods 53 are fixedly connected vertically inside the two circular plates 5. Two clamping plates 51 are slidably connected to the slide rods 53. The two clamping plates 51 are set vertically and pass through the two slide rods 53. A double-acting screw 52 is threaded to one end of each of the two clamping plates 51. After passing through the two clamping plates 51, the double-acting screw 52 is rotatably connected to the circular plate 5. By rotating the double-acting screw 52, ​​the two clamping plates 51 are moved closer or further away along the length of the slide rods 53.

[0045] refer to Figure 1 and Figure 4 Both clamping plates 51 are rotatably connected to mounting bases 8 (see reference). Figure 4 Mounting bracket 8 (reference) Figure 4A blade 56 is fixed on the mounting base 8 (see reference). Figure 4 An elastic element 55, a torsion spring, is provided between the clamping plate 51 and the mounting plate 54. One end of the torsion spring is connected to the mounting plate 54, and the other end is connected to the blade 56. In its natural state, the torsion spring tends to push the blade 56 away from the clamping plate 51, thereby reducing the probability of the blade 56 contacting the metal wire. A baffle 11 is vertically hinged to the support plate 1 to prevent the baffle 11 from falling and affecting the operation of the device. The rewinding wheel 7 (see reference) Figure 4 In the working state, the baffle 11 is located at the rewinding wheel 7 (reference). Figure 4 ) and pressure sensor 287 (reference) Figure 4 )between.

[0046] refer to Figure 2 and Figure 4 After the rewinding wheel 7 is fully wound with metal wire, the metal wire needs to be cut and removed from the rewinding wheel 7. At this time, the two clamping plates 51 cooperate to clamp the metal wire. The operator lowers the baffle 11 (see reference). Figure 1 The mounting plate 54 can separate the mounting base 8 from the pressure sensor 87. By rotating the mounting plate 54, the two blades 56 are aligned. By pressing the mounting plate 54, the two blades 56 are brought closer together and then contacted to cut the metal wire. At the same time, the mounting base 8 is prevented from hitting the pressure sensor 87, which helps to improve the stability and safety of the device.

[0047] refer to Figure 1 and Figure 2 A support block 81 is slidably connected to the mounting base 8. The support block 81 is higher than the rewinding wheel 7. A flattening column 82 is rotatably connected to the lower end of the support block 81. The mounting base 8 supports the flattening column 82 through the support block 81, allowing the flattening column 82 to move vertically. The flattening column 82 is located above the rewinding wheel 7. The metal wire on the rewinding wheel 7 pushes the flattening column 82 to move vertically. During the rewinding process, the lower end face of the flattening column 82 contacts the metal wire, and then flattens the metal wire wound on the outside of the rewinding wheel 7 through its own gravity, which is beneficial for the metal wire to be arranged flat along the length of the rewinding wheel 7.

[0048] refer to Figure 1 and Figure 3 A damper is installed at the upper end of the support block 81. The damper includes a straight plate 812 and a threaded rod 412-1. The threaded rod 412-1 passes through the straight plate 812 and is threadedly connected to the straight plate 812. By rotating the threaded rod 412-1, the end of the threaded rod 412 gradually contacts the mounting seat 8, increasing the friction between the threaded rod 412-1 and the mounting seat 8, thereby increasing the friction between the support block 81 and the mounting seat 8 and improving the working stability of the flattening column 82.

[0049] refer to Figure 1 and Figure 2A protective box 21 is detachably connected to the outside of the wire feeding wheel 2 on the support plate 1. The protective box 21 has a wire outlet along its own length. The outside of the wire outlet is covered with a rubber strip 22. The metal wire passes through the wire outlet and is rewound. When the metal wire breaks, the protective box 21 limits the metal wire on the wire feeding wheel 2, reducing the probability of the metal wire flying and injuring people when it breaks, which helps to improve the safety of the device.

[0050] The implementation principle of a metal wire rewinding fixing fixture in this application embodiment is as follows: the metal wire is pulled by the rewinding wheel 7, passes through the pressure wheel 3 and pulley 4, and is rolled and connected to the pressure wheel 3 and pulley 4. Under the cooperation of pressure sensor 1 86 and pressure sensor 2 87, the driving component 41 pushes the pulley 4 up or down, thereby realizing the tensioning and relaxation of the metal wire. The pressure wheel 3 applies a thrust to the metal wire opposite to that of the pulley 4, so that the metal wire is tensioned. The rolling shaft 6 limits the metal wire. The rolling shaft 6 cooperates with the flattening column 82 to make the metal wire evenly and flatly arranged on the rewinding drum. The clamping plate 51 clamps the metal wire. The operator lowers the baffle 11 to prevent the mounting seat 8 from hitting the pressure sensor 2 87. Then the metal wire is cut and the take-up drum is replaced, which helps to improve the rewinding quality of the metal wire.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
