Description

Technical Field

[0001] The invention relates to the technical field of cable processing equipment, in particular to a wire twister for cable processing and a use method thereof. Background Art

[0002] A wire twister used in cable processing is a tool or device specifically used to twist multiple wires or cables together. It is usually used to connect cable bundles to enhance the mechanical strength and overall durability of the wires.

[0003] Among them, when twisting wires, the wire twister often needs to transport the twisted cables. During transportation, the cables usually need to be squeezed to provide sufficient tension so that the conveying roller can pull the cables. Since the newly twisted cables are usually loose, squeezing may cause the twisted wires to separate, thereby affecting the integrity of the cables. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a wire twister for cable processing, comprising a conveying mechanism, the conveying mechanism also comprising a base, the side wall of the base is rotatably connected with the twister, and the top of the base is fixedly connected with a twisting tube;

[0005] The straightening mechanism comprises a connecting frame 1 fixedly connected to the top of the base, a plurality of inclined grooves are provided on the side wall of the connecting frame 1, and a sliding frame is slidably connected to the outer wall of the connecting frame 1;

[0006] The pre-tightening mechanism comprises a plurality of arc-shaped covers arranged on the top of the base, the outer walls of the plurality of arc-shaped covers are fixedly connected with a second fixing frame, and the outer walls of the plurality of second fixing frames are slidably connected with a rotating frame.

[0007] Preferably, the conveying mechanism also includes a fixed frame 1 fixedly connected to the top of the base, a motor is fixedly connected to the side wall of the fixed frame 1, a conveying roller is fixedly connected to the outer wall of the fixed frame 1, an output end at the side wall of the motor is fixedly connected to the side wall of the conveying roller, a winding sleeve is fixedly connected to the outer wall of the conveying roller, and a bonding frame is fixedly connected to the side wall of the fixed frame 1. When the conveying roller is used to convey the cable, the wires can be further bonded at the same time. The twister is started to twist the wires into cables, the twisted cables are pulled into the twisting tube, and then the cable is wound from the top of the winding sleeve, and after winding several times, it is led out through the top of the groove of the conveying roller. The winding creates a tension between the cable and the conveying roller, so that the cable can be conveyed. Since the shape of the twister is spiral, it can ensure that the cable is transported and moved, and the cable can be transported in a straight line by being led out through the groove of the conveying roller. Then the motor is started to drive the conveying roller to rotate, and the winding sleeve is rotated to convey the cable.

[0008] Preferably, the conveying mechanism further comprises a rotating drum rotatably connected to an inner wall of the fixing frame, a plurality of annular grooves are provided on the inner wall of the rotating drum, a plurality of arc plates are slidably connected to the inner walls of the plurality of annular grooves, an arc spring is fixedly connected to the side walls of the plurality of arc plates, and a connecting ring is fixedly connected to the side walls of the plurality of arc plates;

[0009] Among them, several sliding rods are fixedly connected to the inner walls of several connecting rings, and the outer walls of several sliding rods are slidably connected to the inner wall of the annular groove, and the outer walls of several sliding rods are rotatably connected to the inner wall of the arc plate. Since the rotating drum is in close contact with the winding sleeve, the rotating drum is affected by the friction between the rotating drum and the winding sleeve, thereby driving the rotating drum to rotate and moving the arc plate. When the arc plate moves to the position of the laminating frame, it will lift up the blocking plate of the laminating frame, so that the blocking plate and the winding sleeve are in contact, and then contact the cable. When the blocking plate and the winding sleeve are in contact, they will stop rotating, thereby squeezing the arc plate, causing the arc plate to retract and approach the annular groove to squeeze the arc spring 1, so that the arc spring 1 accumulates rebound force. When the arc plate is separated from the laminating frame, the rebound force of the arc spring 1 will be released, allowing the arc plate to return to its position , gently tap the cable. When the arc plate enters the conveying groove of the winding sleeve, since the winding sleeve is spiral, when the winding sleeve rotates, it will push the arc plate, allowing the arc plate to move horizontally with the winding sleeve. When one of the arc plates moves, it will drive the arc plate in a single annular groove to move together through the connecting ring, ensuring that the arc plate can always be in contact with the cable. By spirally winding the cable and gently tapping the cable, the cable can be straightened and conveyed. At the same time, tapping can help the wires in the cable to be arranged more closely during transportation, reduce the loose state after the initial twisting, and avoid fixed-point compression and transportation causing the cable to be loose. Spiral transportation can increase the contact area between the arc plate and the cable, and avoid intermittent movement of the arc plate, which cannot fully tap the cable.

[0010] Preferably, the straightening mechanism also includes a fixed rod 1 fixedly connected to the inner wall of the sliding frame, the inner walls of several fixed rods 1 are slidably connected to the inner wall of the inclined groove, the tops of several sliding frames are fixedly connected with compression springs, the inner walls of several sliding frames are slidably connected with moving frames, and the inner walls of several moving frames are rotatably connected with straightening rollers. By utilizing the rotation force of the conveying roller, the cable conveyed through the groove of the conveying roller first passes through the arc cover and then is pulled between the straightening rollers, so that the straightening rollers move away from each other, driving the moving frame to move, squeezing the compression spring, and squeezing the cable by the resilience of the compression spring.

[0011] Preferably, the straightening mechanism also includes a turntable fixedly connected to the side wall of the conveying roller, the side wall of the turntable is rotatably connected to a connecting rod, the inner walls of the plurality of moving frames are slidably connected to a connecting frame 2, the side wall of the connecting frame 2 is rotatably connected to the side wall of the connecting rod, and the sides of the plurality of compression springs away from the sliding frame are fixedly connected to the sides of the moving frame close to the connecting frame 1. When the conveying roller rotates, the turntable is driven to rotate, the connecting rod is rotated, and the connecting rod rotates around the center of the turntable, thereby driving the connecting frame 2 to reciprocate, driving the moving frame to move, allowing the sliding frame to move, and driving the fixed rod 1 to slide in the inclined groove. Since the inclined groove has an inclined angle, when the fixing rod moves, the fixing rod will gradually rise, driving the sliding frame to rise, squeezing the compression spring again, allowing the compression spring to gradually increase its rebound force, further squeezing the moving frame, and gradually increasing the force of the straightening roller to squeeze the cable. When the straightening roller reciprocates, the compression force on the cable is gradually increased, and the gradually increased pressure helps to evenly distribute the tension of the cable, thereby reducing the bending and twisting of the cable and helping to straighten the cable. By straightening the cable, it is possible to avoid entanglement of the cable, which may cause the cable to be uneven when the cable is transported in a straight line, causing the cable to slightly tilt.

[0012] Preferably, the pre-tightening mechanism also includes a connecting rod slidably connected to the inner wall of the mobile frame, the outer walls of the plurality of arc-shaped covers are fixedly connected to the rotating frame, the outer walls of the plurality of rotating frames are rotatably connected to the fixed blocks, the side walls of the fixed frame are fixedly connected to the connecting plates, the side walls of the connecting plates are fixedly connected to the side walls of the fixed blocks, the inner walls of the plurality of connecting rods are slidably connected to the inner wall of the rotating frame, the side walls of the connecting plates are rotatably connected to the inner wall of the rotating frame, the force of the moving frame is used to drive the connecting rod to move, and the connecting rod is driven by the sliding The rail slides in the slide groove in the inner wall of the mobile frame, so when the mobile frame rises, the fixed rod 1 will not move. When the mobile frame moves horizontally, it will drive the connecting rod to move. When the connecting rod moves, it will slide on the inner wall of the rotating frame to rotate the rotating frame. When the rotating frame rotates, it will make the fixed frame 2 slide in the rotating frame, pull up the fixed frame 2, drive the arc cover to rise, and make the two arc covers rotate in the fixed block through the rotating frame, so that the arc covers are close to one side of the mobile frame and close to each other, so as to tighten the cable at a single point and increase the clamping force at that place.

[0013] Preferably, the pre-tightening mechanism also includes a fixing rod 2 fixedly connected to the side wall of the connecting plate, a plurality of fitting covers are arranged on the inner wall of the arc cover, an annular plate is slidably connected to the outer wall of the fitting cover, the side wall of the annular plate is fixedly connected to the side wall of the fixing rod 2, a plurality of arc springs 2 are fixedly connected to the outer walls of the plurality of fitting covers, and the side walls of the plurality of arc springs 2 are fixedly connected to the inner wall of the arc cover, and the force of the movement of the arc cover is utilized, when the arc cover rotates, the arc spring 2 will be pulled to move, so that the arc spring 2 accumulates rebound force, and since there is a cable between the two fitting covers and the fitting cover is limited by the annular plate, the fitting cover is limited to follow the arc cover to rise, and continues to fit with the cable, so as to avoid the arc cover squeezing the cable at a single point, which may cause the cable to sag and tilt, thereby ensuring the verticality of the cable, and after the arc spring 2 pulls the fitting cover, the fitting cover and the cable are no longer tightly fitted, so as to avoid the two squeezing forces opposing each other during single-point squeezing.

[0014] A method for using a wire twister for cable processing comprises the following steps:

[0015] S1: Start the twister to twist the wires into cables, pull the twisted cables into the twisting tube, and then wind the cables from the top of the winding sleeve. After winding several turns, lead them out through the top of the groove of the conveying roller;

[0016] S2: The cable can be conveyed in a straight line through the groove of the conveying roller, and then the motor is started to drive the conveying roller to rotate, so that the winding sleeve rotates to convey the cable, because the rotating drum is in close contact with the winding sleeve;

[0017] S3: Affected by the friction between the rotating drum and the winding sleeve, the rotating drum is driven to rotate, causing the arc plate to move. When the arc plate moves to the position of the laminating frame, it will lift up the blocking plate of the laminating frame.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic of the conveying roller to convey the cable while further bonding the wires. The twister is started to twist the wires into cables, and the twisted cables are pulled into the twisting tube. The cable is then wound into the top of the winding sleeve, and after winding for several turns, it is led out through the top of the groove of the conveying roller. The winding creates a tension between the cable and the conveying roller, and the cable can be conveyed. Since the twister is spiral in shape, it can ensure that the cable is transported and moved, and the cable can be transported in a straight line by being led out through the groove of the conveying roller. Then the motor is started to drive the conveying roller to rotate, and the winding sleeve is rotated to convey the cable. Since the rotating drum is in close contact with the winding sleeve, the friction between the rotating drum and the winding sleeve drives the rotating drum to rotate, and the arc plate moves. When the arc plate moves to the bonding frame position, it will lift up the blocking plate of the bonding frame, so that the blocking plate contacts the winding sleeve and then contacts the cable. When the blocking plate contacts the winding sleeve, it will stop rotating, thereby When the cable is in a state of being stretched and pressed, the cable is pressed against the spring 1 and the spring 1 is pressed against the spring 1, and the spring 1 is pressed against the spring 1, so that the cable is pressed against the spring 1. When the cable is in a state of being stretched and pressed, the cable is pressed against the spring 1 and the spring 1 is pressed against the spring 1. When the cable is in a state of being stretched and pressed, the cable is pressed against the spring 1 and the spring 1 is pressed against the spring 1. When the cable is in a state of being stretched and pressed, the cable is pressed against the spring 1 and the spring 1 is pressed against the spring 1. When the cable is in a state of being stretched and pressed, the cable is pressed against the spring 1 and the spring 1 is pressed against the spring 1.

[0020] (2) The present invention utilizes the force of the conveying roller's rotation to make the cable conveyed through the groove of the conveying roller pass through the arc cover first, and then be pulled between the straightening rollers, so that the straightening rollers move away from each other, drive the moving frame to move, squeeze the compression spring, and squeeze the cable through the resilience of the compression spring. When the conveying roller rotates, it will drive the turntable to rotate, so that the connecting rod rotates, so that the connecting rod rotates around the center of the turntable, thereby driving the connecting frame 2 to reciprocate, drive the moving frame to move, and drive the sliding frame to move, so that the fixed rod 1 slides in the inclined groove. Since the inclined groove has an inclined surface, At an oblique angle, when the fixed rod moves, the fixed rod will gradually rise, driving the sliding frame to rise, squeezing the compression spring again, gradually increasing the rebound force of the compression spring, further squeezing the moving frame, and gradually increasing the force of the straightening roller to squeeze the cable. When the straightening roller reciprocates, the compression force on the cable is gradually increased, and the gradually increased pressure helps to evenly distribute the tension of the cable, thereby reducing the bending and twisting of the cable and helping to straighten the cable. By straightening the cable, it is possible to avoid entanglement of the cable, which may cause the cable to be uneven when the cable is transported in a straight line, causing the cable to slightly tilt.

[0021] (3) The present invention utilizes the force of the movement of the mobile frame to drive the connecting rod to move. Since the connecting rod slides through the slide rail and the slide groove in the inner wall of the mobile frame, when the mobile frame rises, the fixed rod 1 will not move. When the mobile frame moves horizontally, it will drive the connecting rod to move. When the connecting rod moves, it will slide on the inner wall of the rotating frame to make the rotating frame rotate. When the rotating frame rotates, it will make the fixed frame 2 slide in the rotating frame, pull up the fixed frame 2, and drive the arc cover to rise. The two arc covers are rotated in the fixed block through the rotating frame, so that the arc covers are close to one side of the mobile frame and close to each other, and the cable is pressed at a single point to increase the clamping force at the location. When the mobile frame returns to its position, it will drive the arc cover to return to its position. Through the reciprocating motion of the mobile frame, the arc cover intermittently squeezes the cable. During the cable winding and transportation process, local stress may appear in some areas of the cable. The intermittent single-point squeezing can effectively disperse these stresses, help fix the position of the cable, pre-straighten the cable, and fix the shape of the cable in advance, which is convenient for subsequent straightening and molding.

[0022] (4) The present invention utilizes the force of the arc cover moving. When the arc cover rotates, it will pull the arc spring 2 to move, allowing the arc spring 2 to accumulate resilience. Since there is a cable between the two fitting covers and the fitting cover is limited by the annular plate, the fitting cover is limited to follow the arc cover to rise. It continues to fit with the cable to avoid the arc cover squeezing the cable at a single point, which may cause the cable to sag and tilt. The verticality of the cable is ensured. After the arc spring 2 pulls the fitting cover, the fitting cover and the cable are no longer tightly fitted, avoiding the two squeezing forces opposing each other during single-point squeezing. When the arc cover returns to its position, it will squeeze the arc spring 2 again, allowing the two fitting covers to approach each other and wrap the cable again. By preventing the cable from sagging during transportation, it can prevent the cable from contacting other non-smooth places, which may cause cable wear, and also avoid the sagging cable affecting straightening.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1 - Figure 3 The present invention is a wire twister for cable processing, comprising a conveying mechanism 1, the conveying mechanism 1 further comprising a base 101, a twister 102 is rotatably connected to the side wall of the base 101, and a twisting tube 103 is fixedly connected to the top of the base 101;

[0037] The straightening mechanism 2 includes a connecting frame 201 fixedly connected to the top of the base 101, a plurality of inclined grooves 202 are provided on the side wall of the connecting frame 201, and a sliding frame 203 is slidably connected to the outer wall of the connecting frame 201;

[0038] The pre-tightening mechanism 3 comprises a plurality of arc-shaped covers 301 arranged on the top of the base 101 , the outer walls of the plurality of arc-shaped covers 301 are fixedly connected with a second fixing frame 302 , and the outer walls of the plurality of second fixing frames 302 are slidably connected with a rotating frame 303 .

[0039] The conveying mechanism 1 also includes a fixed frame 104 fixedly connected to the top of the base 101, a motor 105 is fixedly connected to the side wall of the fixed frame 104, a conveying roller 106 is fixedly connected to the outer wall of the fixed frame 104, the output end of the side wall of the motor 105 is fixedly connected to the side wall of the conveying roller 106, a winding sleeve 107 is fixedly connected to the outer wall of the conveying roller 106, and a bonding frame 108 is fixedly connected to the side wall of the fixed frame 104. When the conveying roller 106 is used to convey the cable, the wire can also be further bonded. The twister 102 is started to twist the wires. Synthesize the cable, pull the twisted cable into the twisting tube 103, then wind the cable from the top of the winding sleeve 107, and after winding several turns, lead it out through the top of the groove of the conveying roller 106. By winding, a tension is created between the cable and the conveying roller 106, so that the cable can be conveyed. Since the shape of the twister 102 is spiral, it can ensure that the cable is transported and moved, and by leading it out through the groove of the conveying roller 106, the cable can be transported in a straight line. Then start the motor 105 to drive the conveying roller 106 to rotate, so that the winding sleeve 107 rotates to convey the cable.

[0040] The conveying mechanism 1 also includes a rotating drum 109 rotatably connected to the inner wall of the fixed frame 104, a plurality of annular grooves 110 are provided on the inner wall of the rotating drum 109, a plurality of arc plates 111 are slidably connected to the inner walls of the plurality of annular grooves 110, an arc spring 112 is fixedly connected to the side walls of the plurality of arc plates 111, and a connecting ring 113 is fixedly connected to the side walls of the plurality of arc plates 111;

[0041] Among them, the inner walls of the plurality of connecting rings 113 are fixedly connected with a plurality of sliding rods 114, the outer walls of the plurality of sliding rods 114 are slidably connected with the inner wall of the annular groove 110, and the outer walls of the plurality of sliding rods 114 are rotatably connected with the inner wall of the arc plate 111. As the rotating drum 109 is in close contact with the winding sleeve 107, the rotating drum 109 is driven to rotate by the friction between the rotating drum 109 and the winding sleeve 107, so that the arc plate 111 moves. When the blocking plate 108 moves to the position of the laminating frame 108, the blocking plate of the laminating frame 108 will be lifted up, so that the blocking plate and the winding sleeve 107 are in contact, and then the cable is in contact. When the blocking plate and the winding sleeve 107 are in contact, the rotation will stop, thereby squeezing the arc plate 111, so that the arc plate 111 retracts to the annular groove 110 to squeeze the arc spring 112, so that the arc spring 112 accumulates the rebound force. When the arc plate 111 is separated from the laminating frame 108, the arc spring 112 The rebound force will be released, allowing the curved plate 111 to return to its position and slightly tap the cable. When the curved plate 111 enters the conveying groove of the winding sleeve 107, since the winding sleeve 107 is spiral, when the winding sleeve 107 rotates, it will push the curved plate 111, allowing the curved plate 111 to move laterally with the winding sleeve 107. When one of the curved plates 111 moves, it will drive the curved plate 111 in the single annular groove 110 to move together through the connecting ring 113, ensuring that the curved plate 111 can always be in contact with the cable. By slightly tapping the cable after spirally winding the cable, the cable can be straightened and conveyed. At the same time, tapping can help the wires in the cable to be arranged more closely during transportation, reduce the loose state after the initial twisting, and avoid the loose cable caused by fixed-point compression transportation. The spiral transportation can increase the contact area between the curved plate 111 and the cable, and avoid the intermittent movement of the curved plate 111, which cannot fully tap the cable.

[0042] For example 2, please refer to Figure 4 - Fig. 9 The present invention is a wire twister for cable processing. On the basis of the first embodiment, the straightening mechanism 2 also includes a fixed rod 204 fixedly connected to the inner wall of the sliding frame 203, the inner walls of several fixed rods 204 are slidably connected to the inner wall of the inclined groove 202, the tops of several sliding frames 203 are fixedly connected with compression springs 205, the inner walls of several sliding frames 203 are slidably connected with moving frames 206, and the inner walls of several moving frames 206 are rotatably connected with straightening rollers 207. By utilizing the rotation force of the conveying roller 106, the cable conveyed through the groove of the conveying roller 106 first passes through the arc cover 301, and then is pulled between the straightening rollers 207, so that the straightening rollers 207 are separated from each other, driving the moving frame 206 to move, squeezing the compression spring 205, and squeezing the cable by the resilience of the compression spring 205.

[0043] The straightening mechanism 2 also includes a turntable 208 fixedly connected to the side wall of the conveying roller 106, and the side wall of the turntable 208 is rotatably connected to a connecting rod 209, and the inner walls of several moving frames 206 are slidably connected to connecting frames 210, and the side wall of the connecting frame 210 is rotatably connected to the side wall of the connecting rod 209, and the side of several compression springs 205 away from the sliding frame 203 is fixedly connected to the side of the moving frame 206 close to the connecting frame 1 201. When the conveying roller 106 rotates, it will drive the turntable 208 to rotate, and the connecting rod 209 will rotate, so that the connecting rod 209 rotates around the center of the turntable 208, thereby driving the connecting frame 210 to move back and forth, driving the moving frame 206 to move, and driving the sliding frame 203 to move, driving The fixing rod 204 slides in the bevel groove 202. Since the bevel groove 202 has an inclined angle, when the fixing rod 204 moves, the fixing rod 204 will gradually rise, driving the sliding frame 203 to rise, squeezing the compression spring 205 again, so that the rebound force of the compression spring 205 gradually increases, further squeezing the moving frame 206, and the force of the straightening roller 207 squeezing the cable is gradually increased. When the straightening roller 207 reciprocates, the compression force on the cable is gradually increased. The gradually increased pressure helps to evenly distribute the tension of the cable, thereby reducing the bending and twisting of the cable and helping to straighten the cable. By straightening the cable, it is avoided that the cable is entangled, which may cause the cable to be uneven when the cable is transported in a straight line, causing the cable to slightly tilt.

[0044] The preload mechanism 3 further includes a connecting rod 304 slidably connected to the inner wall of the mobile frame 206, a rotating frame 305 is fixedly connected to the outer wall of a plurality of arc-shaped covers 301, a fixed block 306 is rotatably connected to the outer wall of a plurality of rotating frames 305, a connecting plate 307 is fixedly connected to the side wall of the fixed frame 104, the side walls of the connecting plate 307 are fixedly connected to the side walls of the fixed block 306, the inner walls of a plurality of connecting rods 304 are slidably connected to the inner wall of the rotating frame 303, the side walls of the connecting plates 307 are rotatably connected to the inner wall of the rotating frame 303, the force of the moving frame 206 is used to drive the connecting rod 304 to move, and since the connecting rod 304 is connected to the moving frame 206 through the slide rail, the connecting rod 304 is The slide groove in the inner wall of the movable frame 206 slides, so when the movable frame 206 rises, the fixed rod 1 204 does not move. When the movable frame 206 moves horizontally, it will drive the connecting rod 304 to move. When the connecting rod 304 moves, it will slide on the inner wall of the rotating frame 303, causing the rotating frame 303 to rotate. When the rotating frame 303 rotates, it will allow the fixed frame 2 302 to slide in the rotating frame 303, pull up the fixed frame 2 302, and drive the arc cover 301 to rise. The two arc covers 301 are rotated in the fixed block 306 through the rotating frame 305, so that the arc covers 301 are close to one side of the movable frame 206 and close to each other, so that the cable is pressed at a single point, increasing the clamping force at that point.

[0045] The preload mechanism 3 further includes a fixing rod 2 308 fixedly connected to the side wall of the connecting plate 307, a plurality of fitting covers 309 are arranged on the inner wall of the arc cover 301, an annular plate 310 is slidably connected to the outer wall of the fitting cover 309, the side wall of the annular plate 310 is fixedly connected to the side wall of the fixing rod 2 308, a plurality of arc springs 2 311 are fixedly connected to the outer walls of the plurality of fitting covers 309, the side walls of the plurality of arc springs 2 311 are fixedly connected to the inner wall of the arc cover 301, and the force of the movement of the arc cover 301 is utilized, when the arc cover 301 rotates, The arc spring 311 will be pulled to move, allowing the arc spring 311 to accumulate resilience. Since there is a cable between the two fitting covers 309 and the fitting cover 309 is limited by the annular plate 310, the fitting cover 309 is limited in the distance it follows the arc cover 301 to rise, and continues to fit with the cable, thereby preventing the arc cover 301 from squeezing the cable at a single point, which may cause the cable to sag and tilt, thereby ensuring the verticality of the cable. After the arc spring 311 pulls the fitting cover 309, the fitting cover 309 is no longer tightly fitted to the cable, thereby avoiding the two squeezing forces opposing each other during single-point squeezing.

[0046] The method for using the wire twister for cable processing includes the following steps:

[0047] S1: Start the twister 102 to twist the wires into cables, pull the twisted cables into the twisting tube 103, and then wind the cables from the top of the winding sleeve 107, and after winding several turns, lead them out through the top of the groove of the conveying roller 106;

[0048] S2: The cable is led out through the groove of the conveying roller 106, and the cable can be conveyed in a straight line. Then the motor 105 is started to drive the conveying roller 106 to rotate, so that the winding sleeve 107 rotates to convey the cable. Since the rotating drum 109 is in close contact with the winding sleeve 107;

[0049] S3: Affected by the friction between the rotating drum 109 and the winding sleeve 107, the rotating drum 109 is driven to rotate, causing the arc plate 111 to move. When the arc plate 111 moves to the position of the laminating frame 108, it will lift up the blocking plate of the laminating frame 108.

[0050] A specific application of this embodiment is: when the present invention is used, the conveying roller 106 is used to convey the cable, and at the same time, the characteristic of further fitting the wires is also enabled. The twister 102 is started to twist the wires into cables, and the twisted cables are pulled into the twisting tube 103. Then, the cables are wound from the top of the winding sleeve 107, and after being wound for several turns, they are led out through the top of the groove of the conveying roller 106. By winding, a tension force is created between the cable and the conveying roller 106, and the cable can be conveyed. Since the twister 102 is in a spiral shape, it can ensure that the cable is conveyed and moved, and the conveying roller The groove 106 is led out to convey the cable in a straight line, and then the motor 105 is started to drive the conveying roller 106 to rotate, so that the winding sleeve 107 rotates to convey the cable. Since the rotating drum 109 is in close contact with the winding sleeve 107, the friction between the rotating drum 109 and the winding sleeve 107 drives the rotating drum 109 to rotate, so that the arc plate 111 moves. When the arc plate 111 moves to the position of the laminating frame 108, it will lift up the blocking plate of the laminating frame 108, so that the blocking plate contacts the winding sleeve 107, and then contacts the cable. When the blocking plate contacts the winding sleeve 107, it will stop rotating, from The arc plate 111 is squeezed to make the arc plate 111 retract close to the annular groove 110 to squeeze the arc spring 112, so that the arc spring 112 accumulates resilience. When the arc plate 111 is separated from the laminating frame 108, the resilience of the arc spring 112 will be released, so that the arc plate 111 returns to its original position and the cable is lightly tapped. When the arc plate 111 enters the conveying groove of the winding sleeve 107, since the winding sleeve 107 is spiral, when the winding sleeve 107 rotates, it will push the arc plate 111, so that the arc plate 111 moves laterally with the winding sleeve 107. When the curved plate 111 moves, the connecting ring 113 drives the curved plate 111 in the single annular groove 110 to move together, ensuring that the curved plate 111 can always be in contact with the cable. By spirally winding the cable and lightly tapping the cable, the cable can be straightened and transported. When the cable is transported, light tapping can help the wires in the cable to be arranged more closely, reduce the loose state after the initial twisting, and avoid the looseness of the cable caused by fixed-point compression transportation. The spiral transportation can increase the contact area between the curved plate 111 and the cable, and avoid the intermittent movement of the curved plate 111, which cannot fully tap the cable.

[0051] By utilizing the force of the conveying roller 106 rotating, the cable conveyed through the groove of the conveying roller 106 first passes through the arc cover 301, and then is pulled between the straightening rollers 207, so that the straightening rollers 207 are moved away from each other, driving the moving frame 206 to move, squeezing the compression spring 205, and squeezing the cable through the resilience of the compression spring 205. When the conveying roller 106 rotates, it will drive the turntable 208 to rotate, so that the connecting rod 209 rotates, so that the connecting rod 209 rotates around the center of the turntable 208, thereby driving the connecting frame 210 to reciprocate, driving the moving frame 206 to move, so that the sliding frame 203 moves, and driving the fixed rod 1 204 in the inclined groove 202. Sliding, since the inclined groove 202 has an inclined angle, when the fixing rod 204 moves, the fixing rod 204 will gradually rise, driving the sliding frame 203 to rise, squeezing the compression spring 205 again, so that the resilience of the compression spring 205 gradually increases, further squeezing the moving frame 206, and the force of the straightening roller 207 squeezing the cable gradually increases. When the straightening roller 207 reciprocates, the compression force on the cable is gradually increased. The gradually increased pressure helps to evenly distribute the tension of the cable, thereby reducing the bending and twisting of the cable and helping to straighten the cable. By straightening the cable, it is avoided that the cable is entangled, which may cause the cable to be uneven when the cable is transported in a straight line, and the cable is slightly tilted;

[0052] The force of the moving frame 206 is used to drive the connecting rod 304 to move. Since the connecting rod 304 slides through the slide rail and the slide groove in the inner wall of the moving frame 206, when the moving frame 206 rises, the fixed rod 1 204 will not move. When the moving frame 206 moves horizontally, it will drive the connecting rod 304 to move. When the connecting rod 304 moves, it will slide on the inner wall of the rotating frame 303, causing the rotating frame 303 to rotate. When the rotating frame 303 rotates, it will cause the fixed frame 2 302 to slide in the rotating frame 303, pull the fixed frame 2 302 up, and drive the arc The arc cover 301 rises, and the two arc covers 301 are rotated in the fixed block 306 through the rotating frame 305, so that the arc cover 301 is close to one side of the mobile frame 206 and close to each other, and the cable is pressed at a single point to increase the pressing force at that place. When the mobile frame 206 returns, it will drive the arc cover 301 to return. The mobile frame 206 reciprocates, so that the arc cover 301 intermittently squeezes the cable. During the cable winding and transportation process, some areas of the cable may have local stress. Intermittent single-point squeezing can effectively disperse these stresses. The force of the arc cover 301 is used to help fix the position of the cable, pre-straighten the cable, and fix the shape of the cable in advance, which is convenient for subsequent straightening and molding. The force of the arc cover 301 moving, when the arc cover 301 rotates, will pull the arc spring 2 311 to move, so that the arc spring 2 311 accumulates resilience. Since there is a cable between the two fitting covers 309 and the fitting cover 309 is limited by the annular plate 310, the fitting cover 309 is limited to follow the arc cover 301 to rise, and continues to fit with the cable, avoiding the arc cover 301 from squeezing the cable at a single point When the cable is being transported, it may cause the cable to sag and tilt, which ensures the verticality of the cable. After the arc spring 2 311 pulls the fitting cover 309, the fitting cover 309 and the cable are no longer tightly fitted, avoiding single-point extrusion and the two extrusion forces opposing each other. When the arc cover 301 returns to its original position, it will squeeze the arc spring 2 311 again, so that the two fitting covers 309 are close to each other, and the cable is wrapped again. By preventing the cable from sagging during transportation, it can prevent the cable from contacting other rough places, which may cause cable wear, and also avoid the sagging cable from affecting straightening.
