Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing, and particularly to a cable support device for cable production and manufacturing equipment. Background Art

[0002] In the process of cable production, stranding is a key link. Stranding is to twist multiple single wires together according to certain rules to form the conductor core wire of the cable. This process is crucial for the performance of the cable because the stranded core wire can not only improve the electrical conductivity of the cable but also enhance its flexibility and tensile strength. During the stranding process, parameters such as the stranding pitch, single wire tension, and stranding direction need to be precisely controlled to ensure that the quality of the core wire meets the strict requirements of cable production. The stranding machine, as the core equipment, is responsible for driving the single wires to perform the stranding action, and its performance directly affects the quality and production efficiency of stranding. The take-up device then orderly collects the finished cable after stranding. The take-up speed and tension control play a key role in the winding quality and storage convenience of the cable. The support device between the stranding machine and the take-up device also has an important role that cannot be ignored. It needs to provide stable support during the cable transmission process to ensure that the cable maintains a proper position and posture, and at the same time, it needs to adapt to various dynamic changes during the cable production process.

[0003] However, during the stranding process, once the take-up device has abnormalities such as jamming, inflexible rotation, or motor failure, it will cause an instant imbalance in the tension on the cable. The instant imbalance in tension makes the cable extremely easy to fall off the support roller. During the falling-off process, the cable may be damaged by scratching, stretching, twisting, etc., which damages the physical structure of the cable and reduces its electrical performance, thus significantly increasing the scrap rate and directly leading to a significant increase in production costs. At the same time, if the rotation speed of the take-up device is too fast, it will continuously tighten the cable. For the stranding machine, the continuously increasing reverse tension will cause huge pressure on its transmission system, stranding components, etc. The belts and chains in the transmission system may break due to overload, and the gears may be worn or damaged by tooth hitting.

[0004] Based on the above viewpoints, the present invention provides a cable support device for cable production and manufacturing equipment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cable support device for cable production and manufacturing equipment. It cuts the cable through a rising cutting blade, and when cutting the cable, the cable on the take-up device is connected to the limiting steel wire through the fixed chuck and the clamping block. When the cable comes off the movable roller, the limiting steel wire will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the residual stress or inertia inside the cable.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A cable support device for a cable production and manufacturing equipment, including a support rail, wherein a tension roller mounting frame is slidably connected in the support rail in a limited manner. The tension roller mounting frame includes a mounting base. Between the movable shafts on both sides of the top of the mounting base, a main tension roller assembly is installed. The main tension roller assembly includes two groups of movably arranged rollers that are mirror-symmetrically distributed. At the centers of the two movably arranged rollers, a limiting cylinder is slidably connected through a spring. On the outer sides of the two movably arranged rollers, fixed frames are rotatably connected in a limited manner. On the inner side wall of the support rail, a tension roller translation assembly is installed. On the inner side wall of the support rail and between the tension roller translation assembly and the main tension roller assembly, a tension roller rotation driving assembly is installed for driving the main tension roller assembly and the tension roller translation assembly to rotate. On the upper side wall of the mounting base, a mounting plate is installed. On the mounting plate, a tension roller braking assembly is installed for driving the left and right sliding of the two side movably arranged rollers. On the mounting plate, a cable cutting assembly is also placed.

[0007] The cable cutting assembly includes a central connection plate, which is arranged between the two movably arranged rollers and sleeved outside the limiting cylinder. On both side walls of the two movably arranged rollers, side limiting plates are fixedly connected. At the middle position of the top of the central connection plate, a cutting blade is installed. The two sides of the cutting blade are embedded in the interiors of the two movably arranged rollers. At the bottom of the central connection plate, a support plate is fixedly connected for supporting the central connection plate and the two side limiting plates.

[0008] Preferably, the tension roller rotation driving assembly includes a driving motor. On the movable end of the driving motor, a driving bevel gear is installed. On the outer side wall of the movably arranged roller close to the driving bevel gear, a driven bevel gear is fixedly installed. The driven bevel gear meshes with the driving bevel gear.

[0009] Preferably, on the upper side wall of the mounting plate, a mounting guide rail is further connected. On the tops of the two movably arranged rollers, bottom driving blocks are installed.

On the outer side wall of the other bottom driving block, a driven toothed plate is fixedly connected. On the upper side wall of the mounting guide rail, a driving gear is installed. The two sides of the driving gear are respectively meshed with the driven toothed plate and the driving toothed plate.

[0010] Preferably, the tension roller braking assembly includes an electric cylinder mounting frame installed on the upper side wall of the mounting plate. Inside the electric cylinder mounting frame, a braking electric cylinder is installed. On the movable end of the braking electric cylinder, a spring band mounting frame is connected. Between the spring band mounting frame and the bottom driving block close to the driving bevel gear, a spring is connected.

[0011] Preferably, a bottom driving wedge block is further fixedly connected to the bottom of the central connection plate, and a main driving wedge block cooperating with the bottom driving wedge block is further fixedly connected to the outer wall of the belt spring mounting bracket through a bracket.

[0012] Preferably, the tension roller translation assembly includes an outer fixed shell, inside which a driving bevel gear is rotatably connected. The driving bevel gear meshes with a driven bevel gear. One end of the driving bevel gear disposed inside the outer fixed shell is fixedly connected to a gear mounting bracket. The other end inside the outer fixed shell is connected with a limiting sleeve in a spring-limited sliding manner. Inside the limiting sleeve, a movable frame is connected through a spring. On the front side wall of the movable frame, a plurality of fixing rods are fixedly connected. The plurality of fixing rods penetrate through the limiting sleeve. On the other end face of the gear mounting bracket, a plurality of driving convex teeth distributed in a circumferential array are provided. On the outer side wall of the movable frame, a movable gear is fixedly connected. At the center of the outer wall of the movable gear, a push rod is rotatably connected. Inside the support rail, a driving lever is connected by a pin shaft. The other end of the push rod is pin-connected to the top of the driving lever. The bottom of the driving lever is pin-connected to a centering driving rod. The centering driving rod is in a limiting sliding connection with the support rail. The other end of the centering driving rod abuts against the outer wall of the bottom driving block.

[0013] Preferably, a driving plate is connected to the inside of the support rail through a spring. On the inner wall of the driving plate, a spring plate is fixedly connected. The top of the spring plate abuts against the outer wall of the limiting sleeve. A pulling plate is installed on the outer wall of the belt spring mounting bracket. The other end of the pulling plate is in a limiting sliding connection with the inner wall of the driving plate. On the outer wall of the gear mounting bracket, a plurality of fixing grooves cooperating with the fixing rods are further formed. On the rear side wall of the mounting base, a tail tooth plate is fixedly connected. The tail tooth plate is disposed between the movable gear and the fixing rods.

[0014] Preferably, a secondary tension roller is connected to the middle position of the rear side wall of the cable cutting assembly through an air spring.

[0015] Preferably, a clamping assembly is installed at the top position of the front side walls of the two fixing frames. The clamping assembly includes sliding rods. The other ends of the two sliding rods are connected with a sleeve through a spring. A magnetic chuck is fixedly connected between the two sleeves. A fixed chuck is attracted by the bottom of the magnetic chuck. In the middle position of the front side wall of the cable cutting assembly, a cable protection device is fixedly connected. The cable protection device includes a reel support. Inside the reel support, a steel cable reel is rotatably connected. A limiting steel cable is wound around the outside of the steel cable reel. On the upper side wall of the reel support, a lifting frame is fixedly connected. A block is placed on the top of the lifting frame. The block cooperates with the fixed chuck. The top end of the limiting steel cable is fixedly connected to the block.

[0016] The present invention has the following technical points and beneficial effects:

[0017] 1. When the driving convex teeth rotate, they will continuously drive the fixed rod and the movable frame connected to the fixed rod to stretch back and forth. During the process of the fixed rod stretching back and forth, the push rod will also be driven to stretch back and forth, thereby driving the driving lever to rotate. During the rotation of the driving lever, the centering driving rod at the bottom of the driving lever drives the bottom driving block to move, and then drives the driving gear to rotate by means of the active tooth plate. During the rotation of the driving gear, it will drive the driven tooth plate to slide, and then drive the two bottom driving blocks to approach each other. When the two bottom driving blocks approach each other, they drive the two movable rollers to approach each other through the fixed frame, thereby centering the wire harness between the two movable rollers and preventing the wire harness from completely detaching from the support device due to deviation.

[0018] 2. When the wire take-up device has abnormalities such as jamming or inflexible rotation, the rising cutting blade is used to cut the cable. While cutting the cable, the movable rollers on both sides still continuously squeeze inward, causing the cable to deform under extrusion. Therefore, during cutting, the cable is not easily detached from the movable rollers on both sides, and the cutting surface is also smoother, facilitating subsequent wiring work.

[0019] 3. After cutting is completed, one end of the cable at the stranding machine is still clamped inside the movable roller. At the same time, the forward-moving movable roller will drag the cable forward, ensuring that the cable output from the stranding machine still maintains a relatively high tension, preventing the sudden disappearance of the tension at the rear end of the cable and the resulting change in the pitch of the stranded wire due to the continuous operation of the stranding machine. At the same time, this method gives the staff a relatively long buffer time to adjust the relevant equipment.

[0020] 4. When cutting the cable, the side limit plate moves upward together. At this time, the clamping block will snap into the bottom of the fixed chuck, so that the cable connected to the wire take-up device is clamped between the fixed chuck and the clamping block. At this time, the cable connected to the wire take-up device is connected to the limit steel wire through the fixed chuck and the clamping block. When the cable detaches from the movable roller, the limit steel wire will limit the cable within a safe range, effectively preventing the cable from rebounding due to the internal residual stress or inertia at the moment of cutting. Such a rebounding cable may cause harm to the operator or damage the surrounding equipment. The limit steel wire can effectively limit the rebounding range of the cable and control the movement of the cable within a safe area, thus ensuring the personal safety of the operator and the integrity of the equipment.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0043] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 5As shown in the figure, an embodiment of the present invention provides a cable support device for cable production and manufacturing equipment, including a support rail 1. A tension roller mounting bracket 6 is slidably connected in the support rail 1 in a limited manner. The tension roller mounting bracket 6 includes a mounting base 61. A main tension roller assembly 4 is installed between the movable shafts on both sides of the top of the mounting base 61. The main tension roller assembly 4 includes two sets of movable rollers 41 distributed symmetrically in a mirror image. A limiting cylinder 42 is slidably connected between the centers of the two movable rollers 41 through a spring. Fixed frames 43 are rotatably connected in a limited manner on the outer sides of the two movable rollers 41. A tension roller translation assembly 5 is installed on the inner side wall of the support rail 1. A tension roller rotation drive assembly 10 for driving the main tension roller assembly 4 and the tension roller translation assembly 5 to rotate is installed on the inner side wall of the support rail 1 between the tension roller translation assembly 5 and the main tension roller assembly 4. A mounting plate 63 is installed on the upper side wall of the mounting base 61. A tension roller braking assembly 11 for driving the left and right sliding of the two movable rollers 41 is installed on the mounting plate 63. A cable cutting assembly 2 is also placed on the mounting plate 63. The middle position of the rear side wall of the cable cutting assembly 2 is connected to a secondary tension roller 3 through an air spring. The two movable rollers 41 approach each other, thereby centering the wire harness between the two movable rollers 41 and preventing the wire harness from completely detaching from the support device due to wire harness offset. The secondary tension roller 3 is connected to the cable cutting assembly 2 through an air spring. Therefore, the secondary tension roller 3 can rotate to select different support angles, thereby providing a certain tension for the wire harness.

[0044] As Figure 2 、 Figure 3 shown in Figure 8 the figure, the cable cutting assembly 2 includes a central connection plate 22. The central connection plate 22 is arranged between the two movable rollers 41 and sleeved on the outer side of the limiting cylinder 42. Side limiting plates 21 are fixedly connected to the two side walls of the two movable rollers 41. A cutting blade 23 is installed at the middle position of the top of the central connection plate 22. The two sides of the cutting blade 23 are embedded in the interiors of the two movable rollers 41. A support plate 25 for supporting the central connection plate 22 and the two side limiting plates 21 is fixedly connected to the bottom of the central connection plate 22. The rising cutting blade 23 cuts the cable.

[0045] As Figure 7 shown in Embodiment Two

[0046] As Figure 5 、 Figure 6 、Figure 8 As shown in Figure 9 Figure [not provided], this embodiment provides another technical solution on the basis of Embodiment 1. An installation guide rail 64 is further connected to the upper side wall of the installation plate 63. Bottom driving blocks 45 are installed at the tops of both movable rollers 41. A driving toothed plate 46 is fixedly connected to the outer side wall of the bottom driving block 45 closer to the driving bevel gear 102, and a driven toothed plate 47 is fixedly connected to the outer side wall of the other bottom driving block 45. A driving gear 48 is installed on the upper side wall of the installation guide rail 64. The two sides of the driving gear 48 are respectively meshed with the driven toothed plate 47 and the driving toothed plate 46. The tension roller brake assembly 11 includes an electric cylinder mounting bracket 112 installed on the upper side wall of the installation plate 63. A brake electric cylinder 111 is installed inside the electric cylinder mounting bracket 112. A leaf spring mounting bracket 113 is connected to the movable end of the brake electric cylinder 111. The leaf spring mounting bracket 113 is connected to the bottom driving block 45 closer to the driving bevel gear 102 by a spring. When the brake electric cylinder 111 pulls the leaf spring mounting bracket 113 to move inward, the leaf spring mounting bracket 113 will drive the two bottom driving blocks 45 to approach each other, and then drive the two movable rollers 41 to approach each other, so that the cable in the middle position of the movable rollers 41 is clamped.

[0047] As Figure 2 shown in Figure 3 Figure [not provided], Figure 4 Figure [not provided], Figure 10 shown in Figure 11 It should be noted that the figures in the original text are not clearly specified. Here, I have used "[not provided]" to indicate the missing figure information. You may need to replace it with the actual figure number according to the specific situation.As shown, a bottom driving wedge block 24 is further fixedly connected to the bottom of the central connection plate 22. A main driving wedge block 115 that cooperates with the bottom driving wedge block 24 is further fixedly connected to the outer wall of the belt spring mounting frame 113 through a bracket. The tension roller translation assembly 5 includes an outer fixed shell 57. An active bevel gear 52 is rotatably connected inside the outer fixed shell 57. The active bevel gear 52 meshes with a driving bevel gear 102. One end of the active bevel gear 52 disposed inside the outer fixed shell 57 is fixedly connected to a gear mounting frame 51. The other end inside the outer fixed shell 57 is connected with a limiting sleeve 56 in a spring-limited sliding manner. A movable frame 53 is connected inside the limiting sleeve 56 through a spring. A plurality of fixing rods 54 are fixedly connected to the front side wall of the movable frame 53. The plurality of fixing rods 54 penetrate through the limiting sleeve 56. A plurality of driving convex teeth 510 distributed in a circumferential array are disposed on the other end face of the gear mounting frame 51. A movable gear 55 is fixedly connected to the outer side wall of the movable frame 53. A push rod 59 is rotatably connected to the center of the outer wall of the movable gear 55. A driving lever 9 is pin-connected inside the support rail 1. The other end of the push rod 59 is pin-connected to the top of the driving lever 9. A centering driving rod 12 is pin-connected to the bottom of the driving lever 9. The centering driving rod 12 is in a limiting sliding connection with the support rail 1. The other end of the centering driving rod 12 abuts against the outer wall of the bottom driving block 45. During the forward and backward telescoping of the fixing rod 54, the push rod 59 will also be driven to telescope forward and backward, thereby driving the driving lever 9 to rotate. During the rotation of the driving lever 9, the centering driving rod 12 at the bottom of the driving lever 9 drives the bottom driving block 45 to move, thereby driving the driving gear 48 to rotate by means of the active toothed plate 46.

[0048] As Figure 10 , Figure 11 and Figure 12As shown, a drive plate 14 is connected inside the support rail 1 by a spring. A spring plate 13 is fixedly connected to the inner wall of the drive plate 14. The top of the spring plate 13 abuts against the outer wall of the limit sleeve 56. A pull plate 114 is installed on the outer wall of the leaf spring mounting bracket 113. The other end of the pull plate 114 is connected to the inner wall of the drive plate 14 in a limited sliding manner. A number of fixing grooves 58 that cooperate with the fixing rods 54 are also formed on the outer wall of the gear mounting bracket 51. A tail tooth plate 62 is fixedly connected to the rear side wall of the mounting base 61. The tail tooth plate 62 is arranged between the movable gear 55 and the fixing rod 54. The leaf spring mounting bracket 113 will drive the two bottom drive blocks 45 to approach each other, and then drive the two movable rollers 41 to approach each other, so that the cable at the middle position of the movable rollers 41 is clamped. At the same time, because the inward movement stroke of the movable roller 41 is relatively long, this causes the driven bevel gear 44 to separate from the driving bevel gear 102, and the movable roller 41 no longer rotates. The leaf spring mounting bracket 113 that slides inward will pull the drive plate 14 to move inward together, and then drive the limit sleeve 56 to slide inward together by means of the spring plate 13. When the limit sleeve 56 slides inward, it will drag the movable frame 53 to approach inward together until the fixing rod 54 is completely inserted into the fixing groove 58. At this time, the movable frame 53 is connected to the gear mounting bracket 51, and at the same time, the movable gear 55 is directly above the tail tooth plate 62. Embodiment III

[0049] As Figure 5 With Figure 7As shown in the figure, this embodiment provides another technical solution on the basis of Embodiment 1 and Embodiment 2. A clamping assembly 8 is installed at the top position of the front side wall of two fixing brackets 43. The clamping assembly 8 includes a sliding rod 81. The other ends of the two sliding rods 81 are connected to a sleeve 82 through a spring. A magnetic chuck 83 is fixedly connected between the two sleeves 82. A fixed chuck 84 is attracted to the bottom of the magnetic chuck 83. A cable protection device 7 is fixedly connected to the middle position of the front side wall of the cable cutting assembly 2. The cable protection device 7 includes a reel bracket 71. A steel cable reel 72 is rotatably connected inside the reel bracket 71. A limiting steel cable 73 is wound around the outside of the steel cable reel 72. A lifting bracket 74 is fixedly connected to the upper side wall of the reel bracket 71. A block 75 is placed on the top of the lifting bracket 74. The block 75 cooperates with the fixed chuck 84. The top end of the limiting steel cable 73 is fixedly connected to the block 75. When cutting the cable, the side limiting plate 21 moves upward together. At this time, the block 75 will be stuck into the bottom of the fixed chuck 84, so that the cable connected to the wire winding device is clamped between the fixed chuck 84 and the block 75. At this time, the cable connected to the wire winding device is connected through the fixed chuck 84, the block 75 and the limiting steel cable 73. When the cable comes out of the movable roller 41, the limiting steel cable 73 will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the internal residual stress or inertia when the cable is cut instantaneously. Such a rebounding cable may cause harm to the operator or damage the surrounding equipment. The limiting steel cable 73 can effectively limit the rebounding range of the cable and control the movement of the cable within a safe area, thus ensuring the personal safety of the operator and the integrity of the equipment.

[0050] Working principle: After the stranding machine completes the stranding process, the stranded wire is led out from the wire outlet of the stranding machine. Its wire harness is supported on the take-up device by the auxiliary tension roller 3 and the movable rollers 41 on both sides, and the auxiliary tension roller 3 is connected to the cable cutting assembly 2 through an air spring. Therefore, the auxiliary tension roller 3 can rotate to select different support angles, thereby providing a certain tension for the wire harness. During the process of wire harness collection, the driving motor 101 drives the driving bevel gear 102 to rotate, which in turn drives the driven bevel gear 44 and the driving bevel gear 52 to rotate together. During the rotation of the driven bevel gear 44, the two movable rollers 41 and the limiting cylinder 42 in the middle rotate together. Through the active rotation of the movable rollers 41, the wear of the wire harness caused by the friction between the wire harness and the movable rollers 41 is avoided. When the driving bevel gear 52 rotates, it will drive the gear mounting bracket 51 and a number of driving convex teeth 510 outside the gear mounting bracket 51 to rotate together. When the driving convex teeth 510 rotate, they will continuously drive the fixed rod 54 and the movable frame 53 connected to the fixed rod 54 to stretch back and forth. During the process of the fixed rod 54 stretching back and forth, it will also drive the push rod 59 to stretch back and forth, thereby driving the driving lever 9 to rotate. During the rotation of the driving lever 9, the centering driving rod 12 at the bottom of the driving lever 9 drives the bottom driving block 45 to move, and then uses the active tooth plate 46 to drive the driving gear 48 to rotate. During the rotation of the driving gear 48, it will drive the driven tooth plate 47 to slide, thereby driving the two bottom driving blocks 45 to approach each other. When the two bottom driving blocks 45 approach each other, they drive the two movable rollers 41 to approach each other through the fixed frame 43, thereby centering the wire harness between the two movable rollers 41 and avoiding the wire harness from completely disengaging from the support device due to wire harness offset.

[0051] At the same time, a tension detection system is provided outside the support device, which can detect the tension of the wire harness in real time. The tension detection system can be an electrical tension detection system that uses a magnetostrictive tension sensor for real-time detection. It mainly uses a sensitive element made of a magnetostrictive material inside the sensor. When the tension of the wire acts on the sensor, it will cause a change in the magnetic characteristics of the sensitive element. By detecting the change in the electromagnetic signal caused by this change in magnetic characteristics, the magnitude of the tension can be accurately measured. When the take-up device has abnormalities such as jamming and inflexible rotation, the tension on the cable will be much greater than the detection threshold of the magnetostrictive tension sensor. Subsequently, the sensor will feedback the detection signal to the external controller, and the external controller will then control the brake cylinder 111 to pull the spring mounting bracket 113 inward. The magnetostrictive tension sensor can be selected as the MK4-S non-contact magnetostrictive linear displacement sensor.

[0052] When the brake electric cylinder 111 pulls the belt spring mounting bracket 113 to move inwards, the belt spring mounting bracket 113 will drive the two bottom drive blocks 45 to approach each other, and then drive the two movable rollers 41 to approach each other, so that the cable at the middle position of the movable rollers 41 is clamped. At the same time, because the inward movement stroke of the movable rollers 41 is relatively long, this causes the driven bevel gear 44 to separate from the driving bevel gear 102, and the movable rollers 41 no longer rotate. And the belt spring mounting bracket 113 sliding inwards will pull the driving plate 14 to move inwards together, and then drive the limit sleeve 56 to slide inwards together by means of the spring plate 13. When the limit sleeve 56 slides inwards, it will drag the movable frame 53 to approach inwards together until the fixed rod 54 is completely inserted into the fixed groove 58. At this time, the movable frame 53 is connected to the gear mounting bracket 51, and at the same time, the movable gear 55 is directly above the tail tooth plate 62. With the continuous rotation of the driving bevel gear 102, the driving bevel gear 52 will drive the fixed rod 54 to rotate together, and then drive the tension roller mounting bracket 6 to slide forward.

[0053] When the tension roller mounting bracket 6 moves forward, the main driving wedge block 115 presses the lower bottom surface of the bottom driving wedge block 24, and then drives the central connection plate 22 and the two side limit plates 21 to move upward, and uses the rising cutting blade 23 to cut the cable. While cutting the cable, the movable rollers 41 on both sides still continue to press inwards, causing the cable to deform due to extrusion. Therefore, during cutting, the cable is not easily detached from the movable rollers 41 on both sides, and the cutting surface is also smoother, which is convenient for subsequent wiring work. After cutting, one end of the cable in the stranding machine is still clamped in the movable rollers 41, and at the same time, the forward-moving movable rollers 41 will drag the cable forward, ensuring that the cable output from the stranding machine still maintains a high tension, avoiding sudden disappearance of the tension at the rear end of the cable, and changes in the pitch of the stranded wire caused by the continuous operation of the stranding machine. At the same time, this method allows the staff to have a long buffer time to adjust the relevant equipment.

[0054] When cutting the cable, the side limit plate 21 moves upward together. At this time, the clamping block 75 will snap into the bottom of the fixed chuck 84, so that the cable connected to the take-up device is clamped between the fixed chuck 84 and the clamping block 75. At this time, the cable connected to the take-up device is connected to the limit steel wire 73 through the fixed chuck 84 and the clamping block 75. When the cable disengages from the movable rollers 41, the limit steel wire 73 will limit the cable within a safe range, effectively avoiding the rebound phenomenon caused by the internal residual stress or inertia of the cable at the moment of cutting. This rebounding cable may cause harm to the operator or damage the surrounding equipment. The limit steel wire 73 can effectively limit the rebound range of the cable and control the movement of the cable within a safe area, thus ensuring the personal safety of the operator and the integrity of the equipment.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
