Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a wire stranding machine and process for processing wires and cables. Background Technology

[0002] A stranding machine is a key piece of equipment in the production of wires and cables. It is mainly used to strand multiple single conductor wires (such as copper wire, aluminum wire, and single cable) into a strand conductor by spiral winding, so as to improve the electrical performance, mechanical strength and flexibility of the cable.

[0003] Most existing stranding machines are driven by motors, causing multiple strands of single wires to rotate around a central axis while the stranded product moves forward in a straight line. The combination of these two movements causes the single wires to be stranded at a certain helix angle (or pitch). During the stranding process, from the perspective of the conflict between mechanical action and material properties, the stranding machine applies significant radial pressure and axial tension to the cable through the rotation of the stranding cage. If the tensile strength of the cable is insufficient, for example, if the copper single wire becomes brittle due to oxidation or work hardening, or if the stranding pitch is not set properly, the conductor may break due to stress concentration when repeatedly bent.

[0004] When operating existing stranding machines, if multiple single strands break due to their own quality or parameter settings, the pre-processed composite conductor will become loose due to the breakage of a section of cable. This leads to a significant decrease in the stranding quality of the composite conductor over a large area, making it impossible to quickly protect the pre-processed composite conductor section when cable breakage occurs. This results in unnecessary economic losses in actual operation. Summary of the Invention

[0005] The purpose of this invention is to provide a wire stranding machine and process for processing wires and cables. It can quickly seal and limit the composite conductor after the stranding is completed by means of a component, so as to avoid the quality of the conductor after processing being greatly affected by the breakage of a single wire, thereby greatly mitigating the economic losses caused by the cable breakage.

[0010] The locking component includes an external toothed ring, a limiting toothed sleeve, and a control component. The external toothed ring is fixedly installed on the side of each guide cylinder. The limiting toothed sleeve is slidably sleeved on each fixed shaft. The control component is connected to the fixed bracket and is used to synchronously drive the limiting toothed sleeve.

[0011] The control unit includes an insertion shaft, a drive plate, a drive screw, an access bevel gear, a double-headed bevel gear shaft, and a drive motor. The insertion shaft is slidably connected to and passes through the limiting tooth groove sleeve. The two drive plates are respectively fixedly installed on both sides of the insertion shaft, and the drive plates are slidably connected to the fixed bracket. The drive screw is threadedly connected to the drive plate and rotatably installed on the fixed bracket. The access bevel gear is fixedly installed on one side of the drive screw. The double-headed bevel gear shaft meshes with the access bevel gear and rotatably installed on the fixed bracket. The output shaft of the drive motor is connected to the double-headed bevel gear shaft, and the drive motor is fixedly installed on the fixed bracket.

[0012] The control assembly further includes a side guide post, an infeed guide frame, a stop roller, a flat guide wheel, an outfeed guide component, and a sensing component. The side guide post is rotatably mounted on one side of the fixed bracket; the infeed guide frame is fixedly mounted on the main operating frame and is located between the feeding frame and the winch device; the stop roller is rotatably mounted on the infeed guide frame; the flat guide wheel is rotatably mounted on the side of the infeed guide frame near the feeding frame; the outfeed guide component is connected to the feeding frame and is used to guide the feeding end of the wire feeding mechanism; the sensing component is connected to the main operating frame and is used to sense and determine the transmission status of the cable to be twisted.

[0013] The discharge guiding component includes a mounting guide, a limiting rotating cylinder, and a guide wheel. The mounting guide is fixedly installed on the side of the feeding rack near the feeding mechanism. Two limiting rotating cylinders are rotatably installed on each mounting guide. The guide wheel is rotatably installed on the mounting guide.

[0014] The sensing component includes an additional bracket, a connecting frame, a movable bracket, a compression wheel, and a pressing component. The additional bracket is fixedly installed on the main operating frame and is located between the feeding frame and the infeed guide frame. The connecting frame is fixedly installed on the additional bracket. The movable bracket is slidably installed on the connecting frame.

The control box is electrically connected to the pressing sensor plate and to the drive motor, and is fixedly mounted on the main operating frame.

[0016] One method for stranding wires and cables, using the aforementioned wire stranding machine, includes the following steps.

[0017] The cable is laid out in an orderly manner using the cable feeding mechanism set on the feeding rack;

[0018] The winch equipment mounted on the main operating frame twists multiple cables together to form a single composite conductor.

[0019] The generated synthetic wire is guided by a fixed bracket and a guide cylinder mounted on the outside of a fixed shaft on a lower pressure frame;

[0020] The guide cylinder located below the lower pressure frame can press the composite wire with the guide cylinder set on the fixed bracket through the pressure application component. When the composite wire is being transmitted normally, the composite wire can be guided and transmitted by the rotation of the guide cylinder on the corresponding fixed shaft.

[0021] When one or more strands of cable break, the locking component will lock the guide cylinder on the fixed bracket and the lower pressure frame, preventing the guide cylinder from rotating normally. At this time, the composite wire pressed by the two guide cylinders cannot transmit normally. At the same time, the slack caused by the cable breakage after being pressed can also be isolated by the mutual pressing of the two guide cylinders.

[0022] The present invention discloses a wire stranding machine and process for processing wires and cables. In actual operation, the wire feeding mechanism on the feeding rack feeds multiple strands of wires in an orderly manner. The winch device on the main operating frame strands the multiple strands of wires to form a composite conductor. The generated composite conductor is guided by the fixed bracket and the guide cylinder mounted on the outside of the fixed shaft on the lower pressure frame. The guide cylinder located below the lower pressure frame can press the composite conductor with the guide cylinder set on the fixed bracket through the pressure application member. During normal transmission of the composite conductor, the rotation of the guide cylinder on the corresponding fixed shaft can realize the guiding and transmission of the composite conductor.

[0023] When one or more strands of cable break, the locking component locks the guide cylinder on the fixed bracket and the lower pressure frame, preventing the guide cylinder from rotating normally. At this time, the composite conductor pressed by the two guide cylinders cannot transmit normally. At the same time, the slack caused by the cable breakage can also be isolated by the mutual pressing of the two guide cylinders. This achieves the ability to quickly lock and limit the composite conductor after the stranding is completed after the cable breaks, avoiding the impact of a single wire break on the quality of the conductor after processing, and thus greatly reducing the economic losses caused by cable breakage.

Detailed Implementation

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] Please see Figures 1 to 11This invention provides a wire stranding machine and process for processing wires and cables: It includes an operating main frame 101, a winch device 102, a feeding rack 103, a wire feeding mechanism 104, and a control assembly. The control assembly includes a fixed bracket 105, a lower pressure frame 106, a fixed shaft 107, a guide cylinder 108, a pressure application component, and a locking component. The pressure application component includes a pressure plate 201, a pressure sensor 202, and a pressure cylinder 203. The locking component includes an external toothed ring 301, a limiting toothed sleeve 302, and a control component. The control component includes an insertion shaft 303, a driving plate 304, and a belt... The moving lead screw 305, the connecting bevel gear 306, the double-headed bevel gear shaft 307, and the drive motor 308, through the aforementioned solution, solve the problem that when operating existing stranding machines, if multiple single strands break due to their own quality or parameter settings, the pre-processed composite conductor will become loose due to the breakage of a section of the cable, resulting in a significant decrease in the strand quality of the composite conductor. This makes it impossible to quickly protect the pre-processed composite conductor section when cable breakage occurs, leading to unnecessary economic losses in actual operation.

[0041] Furthermore, the winch device 102 is mounted on the main operating frame 101, the feeding rack 103 is fixedly mounted on the main operating frame 101, the wire feeding mechanism 104 is disposed on the feeding rack 103, the fixed bracket 105 is fixedly mounted on the main operating frame 101, and the lower pressure frame 106 is slidably mounted on the top of each fixed bracket 105. The fixed shaft 107 is fixedly mounted on both the fixed bracket 105 and the lower pressure frame 106. The guide cylinder 108 is rotatably sleeved on each fixed shaft 107. The pressure applying member is connected to the fixed bracket 105 and is used to apply pressure to the lower pressure frame 106. The locking member is connected to the fixed shaft 107 and is used to limit and lock the guide cylinder 108 disposed on the fixed shaft 107.

[0042] Specifically, the wire feeding mechanism 104 consists of a control drive structure for controlling the orderly wire feeding of the wire feeding mechanism 104 and an installation structure for installing the wire feeding mechanism 104. By installing the wire feeding mechanism 104 and controlling the rotation of the wire feeding mechanism 104, stable wire feeding of the designated wire feeding mechanism 104 can be achieved. Multiple sets of the wire feeding mechanism 104 can be set on the feeding rack 103 according to the actual situation to achieve stable wire feeding of multi-strand cables.

[0043] The winch device 102 consists of a mounting base, a stranding disc, and a drive structure for rotating the stranding disc. The stranding disc has multiple through holes for guiding single-strand cables. By driving the rotation of the stranding disc, the cables passing through the multiple through holes can be twisted together, thereby completing the stranding process of multi-strand cables.

[0044] The fixed bracket 105 is located on the discharge port side of the winch device 102. Multiple sets of the fixed bracket 105 and the subsequent mechanism installed on the fixed bracket 105 can be set according to actual conditions to achieve multi-segment stable protection of the composite cable, so that the impact on the composite cable after stranding can be controlled more effectively and reliably after a single strand cable breaks.

[0045] Each of the fixed brackets 105 is slidably provided with a lower pressure frame 106. The lower pressure frame 106 cooperates with the connecting boss on the top of the fixed bracket 105 through a guide groove protrusion provided on the top. The lower pressure frame 106 and the fixed bracket 105 are also fixedly installed with corresponding fixed shafts 107. Each fixed shaft 107 is rotatably sleeved with a guide cylinder 108. The two guide cylinders 108 provided on the fixed bracket 105 can compress the synthesized cable. During normal operation, the normal rotation of the two guide cylinders 108 can ensure that the synthesized cable in the compressed state can maintain normal transmission.

[0046] In actual operation, the wire feeding mechanism 104 on the feeding rack 103 feeds out multiple strands of cable in an orderly manner. The winch device 102 on the main operating frame 101 twists the multiple strands of cable to form a composite conductor. The generated composite conductor is guided by the guide cylinder 108 on the lower pressure frame 106, which is mounted on the outside of the fixed shaft 107, through the fixed bracket 105. The guide cylinder 108, located below the lower pressure frame 106, can press the composite conductor with the pressure application member in conjunction with the guide cylinder 108 on the fixed bracket 105. During normal transmission of the composite conductor, the rotation of the guide cylinder 108 on the corresponding fixed shaft 107 can be used to guide and transmit the composite conductor.

[0047] When one or more strands of cable break, the locking component will lock the guide cylinder 108 on the fixed bracket 105 and the lower pressure frame 106, preventing the guide cylinder 108 from rotating normally. At this time, the composite conductor pressed by the two guide cylinders 108 cannot transmit normally. At the same time, the slack caused by the cable breakage can also be isolated by the mutual pressing of the two guide cylinders 108. This achieves the ability to quickly lock and limit the composite conductor after the stranding is completed by the provided component after the cable breaks, avoiding the impact of a single wire breakage on the quality of the conductor after processing, and thus greatly reducing the economic losses caused by cable breakage.

[0048] Furthermore, the pressure plate 201 is connected to the lower pressure frame 106; the pressure sensor 202 is fixedly installed at the bottom of the pressure plate 201; the output end of the pressure cylinder 203 is connected to the top of the pressure plate 201, and the pressure cylinder 203 is fixedly installed on the fixed bracket 105.

[0049] In this embodiment, the guide slot protrusion that is slidably connected to the lower pressure frame 106 and the fixed bracket 105 is provided with multiple guide slots. The pressure plate 201 is designed to cooperate with the guide slots provided below the guide slot protrusion of the lower pressure frame 106. The pressure sensor 202 is provided at the bottom of the pressure plate 201. The pressure sensor 202 can detect the pressure applied by the pressure plate 201 to the lower pressure frame 106. The pressure plate 201 is driven by the pressure cylinder 203.

[0050] During normal use, the pressure plate 201 applies a certain pressure to the lower pressure frame 106 through the pressure cylinder 203. The pressure sensor 202 can monitor the pressure applied by the pressure plate 201 and then feed the feedback to the control system of the pressure cylinder 203 to ensure the stability of the pressure applied by the pressure cylinder 203. This allows the guide cylinder 108 below the lower pressure frame 106 to work in conjunction with the guide cylinder 108 set on the fixed bracket 105 to stably and continuously press the synthetic cable.

[0051] Furthermore, each of the guide cylinders 108 is fixedly mounted with an external toothed ring 301 on its side; each of the fixed shafts 107 is slidably fitted with a limiting toothed sleeve 302; the control component is connected to the fixed bracket 105 and is used to synchronously drive the limiting toothed sleeve 302.

[0052] Furthermore, the insertion shaft 303 is slidably connected to the limiting toothed sleeve 302 and passes through the limiting toothed sleeve 302; the two driving plates 304 are respectively fixedly installed on both sides of the insertion shaft 303, and the driving plates 304 are slidably connected to the fixed bracket 105; the driving screw 305 is threadedly connected to the driving plate 304 and rotatably installed on the fixed bracket 105; the access bevel gear 306 is fixedly installed on one side of the driving screw 305; the double-headed bevel gear shaft 307 meshes with the access bevel gear 306 and is rotatably installed on the fixed bracket 105; the output shaft of the driving motor 308 is connected to the double-headed bevel gear shaft 307, and the driving motor 308 is fixedly installed on the fixed bracket 105.

[0053] In this embodiment, each guide cylinder 108 is fixedly provided with an external toothed ring 301 on its side. The external toothed ring 301 matches the toothed groove shape of the limiting toothed sleeve 302. The limiting toothed sleeve 302 is adapted to the track groove provided on the fixed shaft 107. The limiting toothed sleeve 302 is also provided with a through hole for cooperating with the insertion shaft 303.

[0054] The fixed shaft 107 installed on the fixed bracket 105 and the lower pressure frame 106 is fitted with the limiting toothed sleeve 302. The two limiting toothed sleeves 302 provided on each fixed bracket 105 are engaged with the same through shaft 303. The driving plate 304 is fixed on both the upper and lower sides of the through shaft 303. The two driving plates 304 match the sliding groove provided on the fixed bracket 105.

[0055] The limiting toothed sleeve 302, through its cooperation with the insertion shaft 303, can move along with the insertion shaft 303 without being interfered with by the up-and-down movement of the limiting toothed sleeve 302. This is because the fixed shaft 107 on the lower pressure frame 106 will move slightly along with the up-and-down movement of the lower pressure frame 106, and the limiting toothed sleeve 302 fitted on the corresponding fixed shaft 107 will also move up and down accordingly. Therefore, the cooperation between the insertion shaft 303 and the limiting toothed sleeve 302 can avoid interference when driving the limiting toothed sleeve 302.

[0056] Meanwhile, the lower pressure frame 106 and the fixed bracket 105 are also provided with sliding grooves for the sliding of the insertion shaft 303. The two driving plates 304 set on the same fixed bracket 105 are driven by the driving screws 305 respectively. The ends of the two driving screws 305 that cooperate with the two driving plates 304 are fixed with the access bevel gears 306. The two access bevel gears 306 mesh with the two bevel gears set on the double-headed bevel gear shaft 307 one by one. The transmission direction of the two bevel gears set on the double-headed bevel gear shaft 307 is consistent.

[0057] The double-headed bevel gear shaft 307 is driven by the drive motor 308. When the drive motor 308 is driven, the double-headed bevel gear shaft 307 can drive the two drive screws 305 synchronously by driving the two access bevel gears 306, thereby achieving stable driving of the two drive plates 304 and the insertion shaft 303. Driving the upper and lower drive plates 304 to drive the insertion shaft 303 can ensure the stability of the insertion shaft 303 during movement, thereby allowing the insertion shaft 303 to drive the two limiting toothed sleeves 302 to move more smoothly.

[0058] Under normal operating conditions, the limiting toothed sleeve 302 moves to the outside of the fixed shaft 107 under the drive of the insertion shaft 303. At this time, the limiting toothed sleeve 302 does not engage with the corresponding outer toothed ring 301 on the guide cylinder 108. However, when a cable breaks, the insertion shaft 303 can drive the limiting toothed sleeve 302 to move under the drive of the corresponding mechanism, so that the toothed groove of the limiting toothed sleeve 302 can quickly engage with the outer toothed ring 301 on the outside of the guide cylinder 108 on the corresponding side. After the outer toothed ring 301 on the outside of the guide cylinder 108 engages with the limiting toothed sleeve 302, the guide cylinder 108 will be unable to rotate normally due to the limitation of the limiting toothed sleeve 302, thereby pressing and locking the cable to prevent the cable breakage from affecting the subsequent cable synthesis.

[0059] Preferably, the guiding and control assembly provided by the present invention further includes a side guide post 401, a feeding guide frame 402, a stop roller 403, a flat guide wheel 404, a discharge guiding component, and a sensing component. The discharge guiding component includes a mounting guide frame 501, a limiting rotary drum 502, and a guide wheel 503. The sensing component includes an additional bracket 601, a connecting frame 602, a movable bracket 603, a compression wheel 604, and a pressing component. The pressing component includes a pressing plate 605, a spring 606, a pressing sensing plate 607, and a control box 608.

[0060] Furthermore, the side guide post 401 is rotatably mounted on one side of the fixed bracket 105; the feeding guide 402 is fixedly mounted on the operating main frame 101, and the feeding guide 402 is located between the feeding rack 103 and the winch device 102; the blocking roller 403 is rotatably mounted on the feeding guide 402; the flat guide wheel 404 is rotatably mounted on the side of the feeding guide 402 near the feeding rack 103; the discharge guiding component is connected to the feeding rack 103 and is used to guide the feeding end of the wire feeding mechanism 104; the sensing component is connected to the operating main frame 101 and is used to sense and judge the transmission status of the cable that needs to be twisted.

[0061] In this embodiment, when in use, the fixed bracket 105 is provided with two side guide posts 401 on the side that cooperates with the composite cable. The two side guide posts 401 can limit the left and right sides of the composite cable so that the composite cable can be transmitted more stably and orderly.

[0062] The feeding guide 402 is disposed between the unloading rack 103 and the winch device 102. The feeding guide 402 is provided with guide holes that match the wire holes of the stranding reel. Each guide hole is rotatably mounted with a stop roller 403. Each guide hole is also rotatably mounted with a flat guide wheel 404 on the side near the unloading rack 103. The flat guide wheel 404 can guide the cable more stably into the guide hole of the feeding guide 402. Moreover, the rotation of the flat guide wheel 404 can greatly reduce the friction generated during the transmission of a single strand of cable, and prevent the material of the single strand of cable from being damaged due to friction during the transmission process, thereby ensuring the stability of the strength of the single strand of cable before stranding.

[0063] When the abutment roller 403 is set, it can be tilted according to the actual winding situation of the winch device 102, so that when the winch device 102 is winding, the abutment roller 403 can contact the corresponding single cable, thereby reducing the friction generated during the transmission of the single cable by the rotation of the abutment roller 403 and avoiding wear of the single cable.

[0064] Furthermore, the mounting guide 501 is fixedly mounted on the side of the feeding rack 103 near the wire feeding mechanism 104; two limiting rotary drums 502 are rotatably mounted on each mounting guide 501; and the guide wheel 503 is rotatably mounted on the mounting guide 501.

[0065] In this embodiment, the mounting guide 501 and the cable feeding mechanism 104 are arranged in a one-to-one correspondence. The mounting guide 501 is provided with two limiting rotating cylinders 502 and one guide wheel 503. The function of the limiting rotating cylinder 502 is the same as that of the side guide post 401, which is to limit the left and right sides of the specified cable. Then, the rotation of the limiting rotating cylinder 502 reduces the friction generated during cable transmission.

[0066] When the cable feeding mechanism 104 feeds the cable, since the cable winding on the spool is not concentrated in the middle, when the cable appears on the side of the spool, the limiting rotating drum 502 can realize the reversal of the cable transmission. Moreover, the rotation of the limiting rotating drum 502 itself can reduce the friction generated during the transmission process. The guide wheel 503 provided on the mounting guide 501 is to ensure that the single strand of cable can be stably transmitted in the subsequent process.

[0067] Furthermore, the additional support 601 is fixedly installed on the main operating frame 101, and the additional support 601 is located between the feeding frame 103 and the feeding guide 402; the connecting frame 602 is fixedly installed on the additional support 601; the movable support 603 is slidably installed on the connecting frame 602; the compression wheel 604 is rotatably installed on the movable support 603; the extrusion component is connected to the movable support 603 and is used to sense the extrusion state of the movable support 603.

[0068] Furthermore, the pressing plate 605 is slidably mounted on the connecting frame 602; the two sides of the spring 606 are respectively connected to the pressing plate 605 and the movable bracket 603; the pressing sensor plate 607 is fixedly mounted on the top of the pressing plate 605; the control box 608 is electrically connected to the pressing sensor plate 607 and to the drive motor 308, and is fixedly mounted on the main operating frame 101.

[0069] In this embodiment, the additional bracket 601 is installed between the feeding rack 103 and the feeding guide rack 402. The additional bracket 601 is provided with a plurality of connecting racks 602. The number of connecting racks 602 matches the number of cables to be twisted. Each connecting rack 602 is slidably provided with a movable bracket 603. Each movable bracket 603 is provided with a compression wheel 604 at its bottom. The compression wheel 604 can press down on a specified single strand of cable, so that the cable is conducted from the guide wheel 503 to the flat guide wheel 404 provided on the feeding rack.

[0070] The connecting frame 602 is also provided with a pressing plate 605. A spring 606 is provided between the pressing plate 605 and the movable bracket 603. A pressure sensing plate 607 is also fixedly installed on the top of the pressing plate 605. The pressure sensing plate 607 has the same structural principle as the pressure sensor 202. The pressure sensing plate 607 can detect the pressure value generated between the pressing plate 605 and the inner top wall of the connecting frame 602. It should be noted that when the movable bracket 603 slides freely to the bottom of the connecting frame 602 under the influence of gravity, the pressing plate 605 and the... When the spring 606 between the movable brackets 603 is fully extended, the pressure sensing structure on the top of the pressing sensor plate 607 on the pressing plate 605 will not contact the inner wall of the top of the connecting frame 602. Therefore, the pressure value sensed by the pressing sensor plate 607 is zero. Only when the compression wheel 604 moves the spring 606 and the pressing plate 605 upward under the tension of the single cable, causing the spring 606 to contract, will the pressing sensor plate 607 on the top of the pressing plate 605 sense the pressure between the pressing plate 605 and the inner wall of the top of the connecting frame 602.

[0071] In actual operation, the tensioned single-strand cable under normal conditions will drive the compression wheel 604 to move upward, so the pressure sensor plate 607 will sense the specified pressure. However, when a single-strand cable breaks, the movable bracket 603 will fall directly to the bottom of the connecting frame 602 under the action of gravity because it loses the support of the corresponding single-strand cable. At this time, the pressure value sensed by the pressure sensor plate 607 will be zero. Therefore, the control box 608 can judge the operation of the cable by sensing the sensing value of the pressure sensor plate 607. Once a single-strand cable breakage is detected, the control box 608 will drive the drive motor 308 to press and lock the composite cable. At the same time, the control box 608 can also be connected to the subsequent winding drive module and the early warning module so that an emergency stop and an alarm can be triggered when a cable breakage occurs.

[0072] Please see Figure 12 A wire stranding process for processing wires and cables, using the aforementioned wire stranding machine, includes the following steps.

[0073] S1: The multi-strand cable is laid out in an orderly manner by the wire feeding mechanism 104 set on the feeding rack 103;

[0074] S2: The winch device 102 installed on the main operating frame 101 twists multiple cables together to form a single composite conductor;

[0075] S3: The generated synthetic wire is guided by the guide tube 108 mounted on the outside of the fixed shaft 107 on the fixed bracket 105 and the lower pressure frame 106;

[0076] S4: The guide cylinder 108 located below the lower pressure frame 106 can press the composite wire with the guide cylinder 108 set on the fixed bracket 105 through the pressure application member. When the composite wire is being transmitted normally, the guide cylinder 108 can be rotated on the corresponding fixed shaft 107 to guide and transmit the composite wire.

[0077] S5: When one or more strands of cable break, the locking component will lock the guide cylinder 108 on the fixed bracket 105 and the lower pressure bracket 106, so that the guide cylinder 108 cannot rotate normally. At this time, the composite wire pressed by the two guide cylinders 108 cannot transmit normally. At the same time, the slack caused by the cable breakage after being pressed can also be isolated by the mutual pressing of the two guide cylinders 108.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
