Description

Technical Field

[0001] This application relates to the field of wire stripping machine technology, and in particular to an adjustable cable stripping precision control device. Background Technology

[0002] Cable stripping machines are an important process in electronic equipment manufacturing, communications engineering, and home appliance repair. Their purpose is to remove the outer sheath of cables to expose the internal conductors, facilitating subsequent connection or soldering operations. With the miniaturization and increasing precision of electronic equipment, the requirements for wire stripping accuracy are becoming increasingly stringent.

[0003] Chinese Patent No. CN201113199Y discloses a computer wire stripping machine, including a chassis. Inside the chassis, there is a drive device and a transmission device. On the outside of the chassis, there are a rear roller group, a wire cutting and stripping device, and a front roller group in sequence. The front and rear roller groups are each composed of two longitudinally aligned rollers. A wire passes through the front and rear roller groups. A wire stripping device is provided between the front roller group and the wire cutting and stripping device, or between the rear roller group and the wire cutting and stripping device.

[0004] However, in practical applications, after the wire stripping device cuts the insulation layer at both ends of the wire, the insulation layer cannot fall off automatically and requires manual secondary stripping. Since wire processing is usually done in large quantities, the manual secondary processing greatly affects the processing efficiency of the wire, which is a significant shortcoming. Utility Model Content

[0005] To address the issue of the insulation layer failing to detach automatically after being cut at the cable end, this application provides an adjustable cable stripping precision control device.

[0006] The adjustable cable stripping accuracy control device provided in this application adopts the following technical solution:

[0007] An adjustable cable stripping precision control device includes a housing, a control panel, a cutter holder, and a straightening frame. The straightening frame has a straightening component for straightening cables. The housing also has a cable feeding assembly for conveying cables. The cutter holder has a cutting component for cutting cables. The cable feeding assembly includes a central plate that is vertically slidably arranged between the cutter holder and the straightening frame. The housing has a vertical moving component for driving the central plate to slide. An end feeder is located on the side of the housing opposite to the central plate of the cutter holder. The central plate has a middle feeder for reciprocatingly conveying cables at the straightening frame. The end feeder is used for reciprocatingly conveying cables at the cutter holder.

[0008] By adopting the above technical solution, the worker inputs the diameter, length, and insulation thickness of the cable to be cut, as well as the length of the insulation to be removed from the cable end, on the control panel. After the straightening unit straightens the cable, the intermediate conveyor transports the straightened cable from the straightening frame to the cutter holder, where the cutting unit cuts the cable. At this point, the control panel records the initial length of the cable end as zero. Then, the intermediate conveyor moves the cable forward a certain distance, and the cutting unit cuts the insulation at the cable end. After that, the intermediate conveyor moves the cable in the reverse direction, at which point the insulation at the cable end is removed. Then, the end conveyor transports the cable forward to the specified length, and the cutting unit cuts the cable again. Subsequently, the end conveyor moves the cable in the reverse direction a certain distance, and the cutting unit cuts the insulation at the cable end again. At the same time, the end conveyor moves the cable forward again, at which point the insulation at the cable end is removed. This completes the removal of the insulation at both ends of the specified length of cable, improving the processing efficiency and precision control of the cable.

[0009] Optionally, the straightening component includes a straightening plate slidably disposed on the straightening frame. The straightening plate slides along the direction from the straightening frame to the tool holder. The straightening frame has a straightening groove for the straightening plate to slide along. A compression spring supports the straightening plate between the side of the straightening plate near the middle plate and the straightening groove. Two rows of straightening wheels are rotatably disposed on the straightening plate. The two rows of straightening wheels are arranged alternately. The straightening wheels are arranged along the direction from the straightening frame to the tool holder.

[0010] By adopting the above technical solution, when the cable passes between the two rows of straightening rollers, the straightening rollers will straighten the curved cable, which helps to improve the accuracy of cable size cutting.

[0011] Optionally, the tangent includes a stationary tangent mounted on the tangent holder, a tangent cylinder electrically connected to the control panel mounted on the tangent holder, a movable tangent mounted on the piston rod of the tangent cylinder, the movable tangent slidingly engaging with the stationary tangent, and both the stationary tangent and the movable tangent having V-shaped tangent grooves, the V-shaped open end of the tangent groove on the stationary tangent being opposite to the V-shaped open end of the tangent groove on the movable tangent.

[0012] By adopting the above technical solution, when the cable passes between the cleaving groove on the stationary cutter and the cleaving groove on the moving cutter, the moving cutter and the stationary cutter can cut cables of different diameters. At the same time, when the insulation layer on the cable is cut off, under the clamping action of the moving cutter and the stationary cutter, the cable moving in the opposite direction can automatically remove the cut insulation layer at the end.

[0013] Optionally, the intermediate conveyor includes two first support rollers rotatably mounted on the intermediate plate. A first motor electrically connected to the control panel is disposed on the intermediate plate and below the first support rollers. A first synchronous pulley is disposed on the output shaft of the first motor and on both first support rollers. A first synchronous belt is wound between the first synchronous pulley on the output shaft of the first motor and the first synchronous pulley on the first support roller. The two first support rollers are arranged along the direction from the straightening frame to the cutter holder. A first pressure plate is vertically slidably disposed on the intermediate plate. Two first pressure rollers are rotatably disposed on the first pressure plate. The first pressure rollers correspond one-to-one with the first support rollers and are located directly above the first support rollers. A first clamping cylinder electrically connected to the control panel is disposed on the intermediate plate. The first pressure plate is disposed on the piston rod of the first clamping cylinder. The first pressure rollers are used to clamp the cable onto the first support rollers. A central sliding groove is provided on the intermediate plate for the first pressure rollers to slide.

[0014] By adopting the above technical solution, after the straightened cable passes between the first pressure roller and the first support roller, the control panel activates the first clamping cylinder. The piston rod of the first clamping cylinder pushes the first pressure plate close to the first support roller, thereby causing the first pressure plate to drive the first pressure roller to press the cable onto the first support roller. Then, the control panel activates the first motor. The output shaft of the first motor causes the two first support rollers to rotate synchronously through the first synchronous pulley and the first synchronous belt, thereby feeding the cable at a certain speed. This facilitates the control panel in calculating the length of the cable and helps to improve the cutting accuracy of the cable. At the same time, the control panel controls the output shaft of the first motor to rotate in the forward and reverse directions, thereby removing the insulation layer at the end of the cable.

[0015] Optionally, the end conveyor includes two second support rollers rotatably mounted on the housing. A second motor electrically connected to the control panel is mounted on the housing and located below the second support rollers. A second synchronous pulley is mounted on the output shaft of the second motor and on both second support rollers. A second synchronous belt is wound between the second synchronous pulley on the output shaft of the second motor and the second synchronous pulley on the second support roller. A second pressure plate is vertically slidably mounted on the housing. A second pressing cylinder electrically connected to the control panel is mounted on the housing. The second pressure plate is mounted on the piston rod of the second pressing cylinder. Two second pressure rollers are rotatably mounted on the second pressure plate. The second pressure rollers correspond one-to-one with the second support rollers and are located directly above the second support rollers. An end groove is formed between the inner and outer walls of the housing for the second pressure rollers to slide vertically.

[0016] By adopting the above technical solution, after the cable with the end insulation layer removed is conveyed between the second support roller and the second pressure roller, the control panel activates the second pressing cylinder. The piston rod of the second pressing cylinder pushes the second pressure plate close to the second support roller, thereby causing the second pressure plate to drive the second pressure roller to press the cable onto the second support roller. Then, the control panel activates the second motor. The output shaft of the second motor causes the two second support rollers to rotate synchronously through the second synchronous pulley and the second synchronous belt. When the cable has been conveyed to a specified length, the control panel activates the wire cutting cylinder. The wire cutting cylinder cuts the cable through the moving cutter and the stationary cutter. Then, the control panel controls the output shaft of the second motor to rotate in the reverse direction, so as to facilitate the moving cutter and the stationary cutter to cut the insulation layer at the end of the cable. Finally, the control panel controls the output shaft of the second motor to rotate in the forward direction, thereby achieving the effect of removing the insulation layer.

[0017] Optionally, the middle plate is located inside the housing, the vertical moving member includes a lifting cylinder disposed inside the housing and electrically connected to the control panel, a connecting plate is provided on the middle plate, the connecting plate is located on the piston rod of the lifting cylinder, and a clearance groove is provided between the inner side walls of the housing for the first pressure roller and the first support roller to slide.

[0018] By adopting the above technical solution, before the control panel controls the output shaft of the second motor to rotate in the reverse direction, the control panel activates the lifting cylinder. The piston rod of the lifting cylinder drives the middle plate to descend through the connecting plate, thereby reducing the impact on the cutting of the insulation layer at the end of the cable. At the same time, during the descent of the middle plate, since the cable is fixed between the first support roller and the first pressure roller, and since the cable passes between the two rows of straightening rollers, the cable will pull the straightening plate, and the compression spring will be compressed and deformed until the middle plate stops moving. After that, the compression spring gradually recovers its deformation, thereby reducing the possibility of the cable being pulled apart, and at the same time achieving the straightening effect of the cable, further improving the accuracy of cable cutting.

[0019] Optionally, a wire guide is provided on the middle plate, the wire guide slides with the clearance groove, and the wire guide has a wire bundling hole.

[0020] By adopting the above technical solution, the deviation of the cable during the transmission process is reduced.

[0021] Optionally, the conductor frame is provided with a conduit, with one end of the conduit facing away from the conductor frame close to the knife holder, and the cable passes through the conduit.

[0022] By adopting the above technical solution, the possibility of cable bending is reduced, and the accuracy of cable cutting dimensions is further improved.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The worker inputs the diameter, length, and insulation thickness of the cable to be cut, as well as the length of the insulation to be removed from the cable end, on the control panel. After the straightening unit straightens the cable, the intermediate conveyor transports the straightened cable from the straightening frame to the cutter head, where the cutting unit cuts the cable. At this point, the control panel records the initial length of the cable end as zero. Then, the intermediate conveyor moves the cable forward a certain distance, and the cutting unit cuts the insulation at the cable end. After that, the intermediate conveyor moves the cable in the reverse direction, and the insulation at the cable end is removed. Then, the end conveyor transports the cable forward to the specified length, and the cutting unit cuts the cable again. Subsequently, the end conveyor moves the cable in the reverse direction a certain distance, and the cutting unit cuts the insulation at the cable end again. At the same time, the end conveyor moves the cable forward again, and the insulation at the cable end is removed. This completes the removal of the insulation at both ends of the specified length of cable, improving the processing efficiency and precision control of the cable.

[0025] 2. After the straightened cable passes between the first pressure roller and the first support roller, the control panel activates the first clamping cylinder. The piston rod of the first clamping cylinder pushes the first pressure plate closer to the first support roller, thereby causing the first pressure plate to drive the first pressure roller to press the cable onto the first support roller. Then, the control panel activates the first motor. The output shaft of the first motor causes the two first support rollers to rotate synchronously through the first synchronous pulley and the first synchronous belt, thereby feeding the cable at a certain speed. This makes it easier for the control panel to calculate the length of the cable and improves the cutting accuracy of the cable. At the same time, the control panel controls the output shaft of the first motor to rotate in the forward and reverse directions, thereby removing the insulation layer at the end of the cable.

[0026] 3. Before the control panel controls the output shaft of the second motor to rotate in the reverse direction, the control panel activates the lifting cylinder. The piston rod of the lifting cylinder drives the middle plate to descend through the connecting plate, thereby reducing the impact on the cutting of the insulation layer at the cable end. At the same time, during the descent of the middle plate, since the cable is fixed between the first support roller and the first pressure roller, and since the cable passes between the two rows of straightening rollers, the cable will pull the straightening plate, and the compression spring will be compressed and deformed until the middle plate stops moving. Afterwards, the compression spring gradually recovers its deformation, thereby reducing the possibility of the cable being pulled apart and achieving a straightening effect on the cable, further improving the accuracy of cable cutting.

[0030] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0031] This application discloses an adjustable cable stripping accuracy control device.

[0032] Reference Figure 1 An adjustable cable stripping precision control device includes a housing 1, on which a control panel 2, a knife holder 3, and a straightening frame 4 are arranged. A straightening component 5 for straightening cables is arranged on the straightening frame 4. The straightening component 5 includes a straightening plate 51 that is horizontally slidably arranged on the straightening frame 4. The straightening plate 51 slides along the direction from the straightening frame 4 to the knife holder 3.

[0033] Reference Figure 1 The straightening frame 4 is provided with a straightening groove 52 for the straightening plate 51 to slide. A compression spring 53 supports the straightening plate 51 between the side of the straightening plate 51 near the middle plate 61 and the straightening groove 52. Two rows of straightening wheels 54 are rotatably connected to the straightening plate 51. The two rows of straightening wheels 54 are arranged alternately and are arranged along the direction from the straightening frame 4 to the tool holder 3.

[0034] The worker inputs the diameter, length, and insulation thickness of the cable to be cut, as well as the length of the insulation to be removed from the end of the cable to be cut, on the control panel 2. When the cable passes between the two rows of straightening rollers 54, the straightening plate 51 will squeeze the compression spring 53 under the action of friction between the cable and the straightening rollers 54. The compression spring 53 deforms, so that the cable is in a taut state during the conveying process.

[0035] Reference Figure 1The cutter holder 3 is provided with a wire cutting component 7 for cutting cables. The wire cutting component 7 includes a stationary cutter 71 that is bolted to the cutter holder 3. A wire cutting cylinder 72 that is electrically connected to the control panel 2 is bolted to the cutter holder 3. A movable cutter 73 is bolted to the piston rod of the wire cutting cylinder 72.

[0036] Reference Figure 1 The moving cutter 73 and the stationary cutter 71 are slidably engaged. Both the stationary cutter 71 and the moving cutter 73 are provided with a V-shaped tangent groove 74. The V-shaped open end of the tangent groove 74 on the stationary cutter 71 is opposite to the V-shaped open end of the tangent groove 74 on the moving cutter 73.

[0037] When the cable passes between the stationary cutter 71 and the moving cutter 73, the cable can be cut as the tangent groove 74 on the moving cutter 73 gradually closes with the tangent groove 74 on the stationary cutter 71. At the same time, by controlling the distance between the tangent groove 74 on the moving cutter 73 and the tangent groove 74 on the stationary cutter 71, the insulation layer on the surface of the cable can be cut without damaging the metal conductor.

[0038] Reference Figure 1 and Figure 2 The housing 1 is provided with a cable conveying assembly 6 for conveying cables. The cable conveying assembly 6 includes a central plate 61, which is located inside the housing 1. The central plate 61 is vertically slidably arranged between the tool holder 3 and the straightening frame 4. The housing 1 is provided with a vertical moving member 62 for driving the central plate 61 to slide.

[0039] Reference Figure 1 and Figure 2 The vertical moving component 62 includes a lifting cylinder 621 that is bolted inside the housing 1 and electrically connected to the control panel 2. A connecting plate 622 is welded on the middle plate 61. The connecting plate 622 is bolted to the piston rod of the lifting cylinder 621. A middle conveying component 63 for reciprocatingly conveying the cables at the straightening frame 4 is arranged on the middle plate 61.

[0040] Reference Figure 1 and Figure 2 The intermediate conveyor 63 includes two first support rollers 631 rotatably connected to the intermediate plate 61. The two first support rollers 631 are arranged along the direction from the straightening frame 4 to the cutter holder 3. A first motor 632 electrically connected to the control panel 2 is bolted on the intermediate plate 61 and below the first support rollers 631. A first synchronous pulley 633 is bolted to the output shaft of the first motor 632 and to both first support rollers 631.

[0041] Reference Figure 2A first synchronous belt 634 is wound between the first synchronous pulley 633 on the output shaft of the first motor 632 and the first synchronous pulley 633 on the first support roller 631. A first pressure plate 635 is vertically slidably arranged on the middle plate 61. Two first pressure rollers 636 are rotatably connected to the first pressure plate 635. The first pressure rollers 636 correspond one-to-one with the first support rollers 631. The first pressure rollers 636 are located directly above the first support rollers 631.

[0042] Reference Figure 2 A first pressing cylinder 637, which is electrically connected to the control panel 2, is bolted to the middle plate 61. A first pressure plate 635 is bolted to the piston rod of the first pressing cylinder 637. A first pressure roller 636 is used to press the cable onto the first support roller 631. A middle sliding groove 638 is provided on the middle plate 61 for the first pressure roller 636 to slide.

[0043] Reference Figure 1 and Figure 2 The inner sidewalls of the housing 1 are vertically provided with clearance grooves 623 for the sliding of the first pressure roller 636 and the first support roller 631. A wire frame 8 is bolted to the middle plate 61. The wire frame 8 is slidably engaged with the clearance groove 623. The wire frame 8 is provided with a cable bundling hole 9 for the cable to pass through. A through pipe 10 is bolted to the wire frame 8. The end of the through pipe 10 facing away from the wire frame 8 is close to the knife holder 3. The cable passes through the through pipe 10.

[0044] After the straightened cable passes between the first pressure roller 636 and the first support roller 631, the control panel 2 activates the first pressing cylinder 637. The piston rod of the first pressing cylinder 637 drives the first pressure plate 635 to descend. The first pressure plate 635 drives the first pressure roller 636 to press the cable onto the first support roller 631. Then, the control panel 2 activates the first motor 632. The output shaft of the first motor 632 causes the two first support rollers 631 to rotate synchronously through the first synchronous pulley 633 and the first synchronous belt 634.

[0045] Guided by the cable bundle hole 9 and the through tube 10, the cable is gradually conveyed between the stationary cutter 71 and the moving cutter 73. Then, the control panel 2 activates the cutting cylinder 72. The piston rod of the cutting cylinder 72 drives the moving cutter 73 to slide downward, thereby cutting the cable between the stationary cutter 71 and the moving cutter 73. Afterward, the piston rod of the cutting cylinder 72 drives the moving cutter 73 to reset. At this time, the control panel 2 records that the end distance of the cable is zero.

[0046] When the control panel 2 starts the first motor 632, the output shaft of the first motor 632 rotates in the forward direction, causing the cable to continue to be conveyed forward. After one end has traveled a certain distance, the first motor 632 stops working. Then, the control panel 2 starts the wire cutting cylinder 72 again. The piston rod of the wire cutting cylinder 72 pushes the moving cutter 73 down a certain distance, and the insulation layer on the cable is cut off. At this time, the control panel 2 controls the output shaft of the first motor 632 to rotate in the reverse direction, and the insulation layer at the end of the cable is removed. After that, the piston rod of the wire cutting cylinder 72 drives the moving cutter 73 to reset again.

[0047] Reference Figure 1 and Figure 2 An end conveyor 64 is arranged on the side of the housing 1 facing away from the middle plate 61 of the tool holder 3. The end conveyor 64 is used to reciprocate to convey the cable at the tool holder 3. The end conveyor 64 includes two second support rollers 641 rotatably connected to the housing 1. The second support rollers 641 pass through the inner and outer walls of the housing 1. The two second support rollers 641 are arranged along the direction from the straightening frame 4 to the tool holder 3. A second motor 642, which is electrically connected to the control panel 2, is bolted on the housing 1 and below the second support rollers 641.

[0048] Reference Figure 2 A second synchronous pulley 643 is bolted to the output shaft of the second motor 642 and to both second support rollers 641. A second synchronous belt 644 is wound between the second synchronous pulley 643 on the output shaft of the second motor 642 and the second synchronous pulley 643 on the second support roller 641. A second pressure plate 645 is vertically slidably arranged inside the housing 1. A second pressing cylinder 646, which is electrically connected to the control panel 2, is bolted inside the housing 1.

[0049] Reference Figure 2 The second pressure plate 645 is bolted to the piston rod of the second pressing cylinder 646. Two second pressure rollers 647 are rotatably connected to the second pressure plate 645. The second pressure rollers 647 correspond one-to-one with the second support rollers 641. The second pressure rollers 647 are located directly above the second support rollers 641. An end groove 648 is provided between the inner and outer walls of the housing 1 for the second pressure rollers 647 to slide vertically.

[0050] Control panel 2 controls the output shaft of the first motor 632 to rotate in the forward direction again. The cable passes between the moving cutter 73 and the stationary cutter 71 until the cable is delivered between the second support roller 641 and the second pressure roller 647. Then, control panel 2 activates the second pressing cylinder 646. The piston rod of the second pressing cylinder 646 pushes the second pressure plate 645 close to the second support roller 641, so that the second pressure plate 645 drives the second pressure roller 647 to press the cable onto the second support roller 641.

[0051] Afterwards, the control panel 2 controls the output shaft of the second motor 642 to rotate in the forward direction. The output shaft of the second motor 642 causes the two second support rollers 641 to rotate synchronously in the forward direction through the second synchronous pulley 643 and the second synchronous belt 644, so that the cable continues to be conveyed until the conveyed cable reaches the designed length. Then, the control panel 2 starts the wire cutting cylinder 72. The piston rod of the wire cutting cylinder 72 cuts the cable through the moving cutter 73 and the stationary cutter 71.

[0052] At this time, the control panel 2 activates the lifting cylinder 621. The piston rod of the lifting cylinder 621 drives the middle plate 61 to descend through the connecting plate 622. During the descent of the middle plate 61, since the cable is fixed between the first support roller 631 and the first pressure roller 636, and since the cable passes between the two rows of straightening rollers 54, the cable will pull the straightening plate 51. The compression spring 53 is compressed and deformed, and the cable is straightened until the middle plate 61 stops moving. After that, the compression spring 53 gradually returns to its original shape.

[0053] Control panel 2 controls the output shaft of the second motor 642 to rotate in the opposite direction, causing the cut cable to slide in the opposite direction by one end. Then, the insulation layer on the cable is cut by the cutting cylinder 72. The operation is repeated to remove the insulation layer at the end of the cable, thereby completing the processing of the cable of a specified length.

[0054] The implementation principle of the adjustable cable stripping accuracy control device in this application embodiment is as follows: The worker inputs the diameter, length and insulation thickness of the cable to be cut, as well as the length of insulation to be removed from the end of the cable to be cut, on the control panel 2. When the cable passes between the two rows of straightening rollers 54, the straightening plate 51 will squeeze the compression spring 53 under the action of friction between the cable and the straightening rollers 54. The compression spring 53 deforms, so that the cable is in a tensioned state during the conveying process.

[0055] When the cable passes between the stationary cutter 71 and the moving cutter 73, the cable can be cut as the tangent groove 74 on the moving cutter 73 gradually closes with the tangent groove 74 on the stationary cutter 71. At the same time, by controlling the distance between the tangent groove 74 on the moving cutter 73 and the tangent groove 74 on the stationary cutter 71, the insulation layer on the surface of the cable can be cut without damaging the metal conductor.

[0056] After the straightened cable passes between the first pressure roller 636 and the first support roller 631, the control panel 2 activates the first pressing cylinder 637. The piston rod of the first pressing cylinder 637 drives the first pressure plate 635 to descend. The first pressure plate 635 drives the first pressure roller 636 to press the cable onto the first support roller 631. Then, the control panel 2 activates the first motor 632. The output shaft of the first motor 632 causes the two first support rollers 631 to rotate synchronously through the first synchronous pulley 633 and the first synchronous belt 634.

[0057] Guided by the cable bundle hole 9 and the through tube 10, the cable is gradually conveyed between the stationary cutter 71 and the moving cutter 73. Then, the control panel 2 activates the cutting cylinder 72. The piston rod of the cutting cylinder 72 drives the moving cutter 73 to slide downward, thereby cutting the cable between the stationary cutter 71 and the moving cutter 73. Afterward, the piston rod of the cutting cylinder 72 drives the moving cutter 73 to reset. At this time, the control panel 2 records that the end distance of the cable is zero.

[0058] When the control panel 2 starts the first motor 632, the output shaft of the first motor 632 rotates in the forward direction, causing the cable to continue to be conveyed forward. After one end has traveled a certain distance, the first motor 632 stops working. Then, the control panel 2 starts the wire cutting cylinder 72 again. The piston rod of the wire cutting cylinder 72 pushes the moving cutter 73 down a certain distance, and the insulation layer on the cable is cut off. At this time, the control panel 2 controls the output shaft of the first motor 632 to rotate in the reverse direction, and the insulation layer at the end of the cable is removed. After that, the piston rod of the wire cutting cylinder 72 drives the moving cutter 73 to reset again.

[0059] Control panel 2 controls the output shaft of the first motor 632 to rotate in the forward direction again. The cable passes between the moving cutter 73 and the stationary cutter 71 until the cable is delivered between the second support roller 641 and the second pressure roller 647. Then, control panel 2 activates the second pressing cylinder 646. The piston rod of the second pressing cylinder 646 pushes the second pressure plate 645 close to the second support roller 641, so that the second pressure plate 645 drives the second pressure roller 647 to press the cable onto the second support roller 641.

[0060] Afterwards, the control panel 2 controls the output shaft of the second motor 642 to rotate in the forward direction. The output shaft of the second motor 642 causes the two second support rollers 641 to rotate synchronously in the forward direction through the second synchronous pulley 643 and the second synchronous belt 644, so that the cable continues to be conveyed until the conveyed cable reaches the designed length. Then, the control panel 2 starts the wire cutting cylinder 72. The piston rod of the wire cutting cylinder 72 cuts the cable through the moving cutter 73 and the stationary cutter 71.

[0061] At this time, the control panel 2 activates the lifting cylinder 621. The piston rod of the lifting cylinder 621 drives the middle plate 61 to descend through the connecting plate 622. During the descent of the middle plate 61, since the cable is fixed between the first support roller 631 and the first pressure roller 636, and since the cable passes between the two rows of straightening rollers 54, the cable will pull the straightening plate 51. The compression spring 53 is compressed and deformed, and the cable is straightened until the middle plate 61 stops moving. After that, the compression spring 53 gradually returns to its original shape.

[0062] Control panel 2 controls the output shaft of the second motor 642 to rotate in the opposite direction, causing the cut cable to slide in the opposite direction by one end. Then, the insulation layer on the cable is cut by the cutting cylinder 72. The operation is repeated to remove the insulation layer at the end of the cable, thereby completing the processing of the cable of a specified length.

[0063] 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.
