Description

Technical Field

[0001] This invention relates to the field of cable production equipment technology, specifically to a cable outer sheath winding device. Background Technology

[0002] The cable sheath (also known as the outermost protective barrier in the cable structure) is the outermost protective barrier. Its core function is to resist damage to the internal conductor and insulation layer from the external environment. The sheath provides basic protection such as waterproofing, corrosion resistance, and mechanical shock resistance through physical isolation. Cable sheath winding equipment is a special mechanical device used in cable manufacturing to precisely, continuously, and tightly wrap one or more layers of strip material around the outside of the cable core (conductor + insulation layer + possible shielding layer).

[0003] When wrapping the armor layer around the outer sheath of a cable, the metal strip is often wrapped around the cable surface in a spiral overlapping manner. During this process, the metal strip needs to maintain appropriate tension. However, in actual operation, the metal strip is prone to swinging when it is pulled, which may cause the metal strip to vibrate. This vibration may cause the guide roller used to squeeze the metal strip to loosen, which in turn causes the tension of the metal strip to drop. This will affect the bonding effect between the metal strip and the cable, making it difficult to form a stable and tight wrapping. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a cable outer sheath winding device, comprising: The covering mechanism has a drive assembly installed on its side wall and a winding assembly rotatably installed on its inner wall. The winding assembly is used to wrap the armor layer around the surface of the cable. A control mechanism, mounted on the side wall of the winding assembly, is used to control the tension of the metal strip; and A buffer mechanism, located on the side wall of the winding assembly, is used to reduce the vibration amplitude of the metal strip. When wrapping the cable with the armor layer, the cable is passed through the center of the wrapping assembly, and then the wrapping assembly is rotated by the drive assembly to wrap the armor layer around the cable surface. Then, the tension of the armor layer is controlled by the control mechanism to effectively prevent the metal strip from vibrating frequently when it is being pulled, which would reduce the tension of the metal strip and affect the tight wrapping of the cable by the metal strip. Finally, the vibration amplitude of the metal strip is reduced by the buffer mechanism.

[0005] Preferably, the covering mechanism includes a support platform; The drive component is fixedly installed on the side wall of the drive assembly and the side wall of the support platform, and is used to drive the winding assembly to rotate; The outer wall of the winding assembly is rotatably mounted on the inner wall of the support platform for winding an armor layer onto the cable surface. The process involves inserting the cable to be wrapped with armor into the winding assembly, then connecting the cable to a traction device, which pulls the cable to move it, and finally, rotating the winding assembly to wrap the cable with the armor layer.

[0006] Preferably, the drive assembly includes a pulley set disposed on the side wall of the support platform, and a motor is fixedly connected to the side wall of the support platform; The output end of the motor is fixedly connected to the side wall of the pulley assembly, and a protective cover is fixedly connected to the side of the support platform away from the pulley assembly. The winding assembly includes a rotating disk rotatably connected to the inner wall of the support platform, the outer wall of the rotating disk being fixedly connected to the inner wall of the pulley assembly, and a connecting ring being fixedly connected to the side wall of the rotating disk. A fixing plate is fixedly connected to the inner wall of the connecting ring, and two metal strip cylinders are rotatably connected to the inner wall of the fixing plate.

[0007] Preferably, the control mechanism includes: The extrusion assembly is fixedly installed on the side wall of the fixed plate and is used to extrude metal strips; The pressing component is fixedly installed on the side wall of the fixed plate and is used to press and squeeze the component. In the process of the winding assembly wrapping the cable surface with the coating layer, the tension of the metal strip is controlled by the extrusion assembly. When the tension weakens, the pressing assembly will press the extrusion assembly to increase the tension again, which effectively prevents the metal strip from vibrating frequently, causing the roller frame to separate from the metal strip, resulting in a decrease in the tension of the metal strip and affecting the tight wrapping of the cable by the metal strip.

[0008] Preferably, the buffer mechanism includes: The reciprocating assembly is fixedly installed on the side wall of the fixed plate and is used to reciprocate and compress gas. The damping component is slidably connected to the side wall of the fixed plate to reduce the vibration amplitude of the metal strip. When the pressing component squeezes the squeezing component, the reciprocating component squeezes the gas, allowing the gas to enter the damping component. When the damping component moves under the influence of the vibration force of the metal belt, it absorbs the vibration of the metal belt and reduces the vibration amplitude of the metal belt.

[0009] Preferably, the extrusion assembly includes two roller frames 1 fixedly connected to the side wall of the fixed plate, two roller frames 2 slidably connected to the side wall of the fixed plate, and threaded rods 1 rotatably connected to the inner walls of the two roller frames 2. Both threaded rods are fixedly connected to the side walls of the two threaded rods, and three spring arc blocks are slidably connected to the inner walls of the two threaded rods. Both extrusion sleeves have rotating rings rotatably connected to their inner walls, and both threaded rods are threaded to the inner wall of the fixed plate at their outer walls. Both extrusion sleeves have threaded rods 2 threaded to their inner walls. When the operator pulls the metal strip on the metal strip drum, the metal strip passes between roller frame one and roller frame two. The operator rotates the extrusion sleeve counterclockwise, which drives the threaded rod one to rotate. This pushes roller frame two towards the metal strip, compressing the metal strip and causing it to undergo slight elastic deformation, increasing the tension of the metal strip. After the tension is adjusted, the operator rotates the rotating ring so that the rotating ring contacts the top of roller frame two. Then, the operator rotates the threaded rod two counterclockwise, causing the threaded rod two to move towards the threaded rod one. The threaded rod two then compresses the spring arc block towards the rotating ring, causing the spring arc block to compress the rotating ring. At the same time, the spring arc block accumulates rebound force. Then, the motor is started to drive the pulley set to rotate, which in turn causes the rotating disk to rotate, making the connecting ring and the fixed plate rotate. This causes the metal strip drum to rotate around the center of the rotating disk. At the same time, the traction device is started to pull the cable. As the fixed plate rotates, the metal strip on the metal strip drum will be stretched and wrapped around the cable to form a coating layer.

[0010] Preferably, the pressing assembly includes two limiting blocks fixedly connected to the side wall of the fixed plate, a concave-convex ring fixedly connected to the inner wall of the protective cover, and two spring sliding brackets provided on the side wall of the fixed plate, with the outer walls of the two spring sliding brackets slidably connected to the inner walls of the two limiting blocks. During the continuous stretching of the metal strip, vibration is generated, causing the roller frame 2 to be frequently affected by vibration. When the threaded rod 1 loosens, the threaded rod 1 will rotate clockwise. As the spring arc block squeezes the rotating ring, the rotating ring will be driven to rotate through the spring arc block when the compression sleeve rotates, causing the left side of the rotating ring to tilt up. When the fixed plate rotates, it will drive the spring sliding frame to rotate. When the spring sliding frame moves to the protruding position of the concave and convex rings, the spring sliding frame will be squeezed, causing it to accumulate rebound force. When the spring sliding frame is compressed, it will move towards the rotating ring. When the rotating ring is raised, the spring sliding frame will descend and contact the rotating ring, pushing the rotating ring to rotate counterclockwise. This causes the threaded rod to rotate, pushing the roller frame to compress the metal strip again, keeping the metal strip under sufficient tension. This effectively prevents the metal strip from being pulled and vibrating frequently, which could cause the roller frame to separate from the metal strip, resulting in a decrease in the tension of the metal strip and affecting the tight wrapping of the cable by the metal strip.

[0011] Preferably, the reciprocating assembly includes two pneumatic sleeves disposed on the side wall of the fixed plate, and a piston rod is slidably connected to the inner wall of each of the two pneumatic sleeves; Both pneumatic sleeves have air supply pipes that run through their inner walls. The side of each pneumatic sleeve away from the extrusion sleeve is fixedly connected to the side of each limiting block that is closer to the extrusion sleeve. One-way valves are slidably connected to the inner walls of the two gas pipes. The side of the two piston rods away from the extrusion sleeve is fixedly connected to the side of the two spring sliding frames close to the extrusion sleeve. Six air pressure holes are opened on the inner wall of the air pressure sleeve. When the metal strip is pulled through between roller frame one and roller frame two, the metal strip will come into contact with the extrusion roller, causing the extrusion roller to extrude the metal strip. When the spring sliding frame descends, it will drive the piston rod to descend. When the piston rod descends past the air pressure hole, it will extrude the gas in the air pressure sleeve. At this time, the extruded gas will be blocked by the one-way valve, so the gas pressure will increase. As the gas pressure increases, the high-pressure gas will push the one-way valve to move, removing the obstruction to the gas. The high-pressure gas will then enter the closed sleeve and separate from the protruding position of the concave and convex rings during the rotation of the spring sliding frame. The spring-loaded sliding frame will release its rebound force, causing it to return to its original position and the piston rod to rise. Once the piston rod returns to its original position, the air pressure port will reconnect with the bottom of the piston rod, allowing outside gas to enter the air pressure sleeve. This continues until the spring-loaded sliding frame is pressurized and descends again, causing the piston rod to squeeze gas into the closed sleeve again, continuously injecting gas into the closed sleeve and keeping the gas inside the closed sleeve under high pressure.

[0012] Preferably, the mitigation assembly includes two fixed brackets slidably connected to the side wall of the fixed plate, each fixed bracket having a spring piston block fixedly connected to its side wall, and two sealing sleeves fixedly connected to the side wall of the fixed plate. The inner walls of the two sealing sleeves are slidably connected to the outer walls of the two spring piston blocks, and each sealing sleeve has a throttling orifice in its inner wall. The inner walls of the two sealing sleeves are also connected to the outer walls of the two gas delivery pipes. When the vibration force generated by the metal strip is large, it is transmitted to the extrusion roller and pushes the fixed frame to move towards the pneumatic sleeve. The fixed frame will drive the spring piston block to squeeze the gas in the closed sleeve, so that the spring piston block accumulates the rebound force. At this time, the squeezed gas will be ejected through the throttle hole. Since the throttle hole is small, the gas discharge speed is slow, which slows down the movement speed of the fixed frame, absorbs the vibration of the metal strip, and reduces the vibration amplitude of the metal strip.

[0013] Preferably, the damping assembly further includes a compression roller rotatably connected to the inner wall of the fixed frame, a connecting rod fixedly connected to the side wall of each of the two spring sliding frames, a connecting rod rotatably connected to the side wall of each of the two connecting rods, and the side wall of each of the two compression rollers rotatably connected to the inner wall of each of the two connecting rods. When the spring sliding frame descends, it drives the connecting rod to descend, pushing the connecting rod to move. The connecting rod rotates around the center of the extrusion roller. As the connecting rod moves up and down with the spring sliding frame, the connecting rod pushes the extrusion roller to rotate. Since the extrusion roller squeezes the metal strip, when the extrusion roller rotates, it conveys the metal strip to slide downwards, making the metal strip above roller frame one and roller frame two in a loose state, forming a buffer section. This effectively prevents the metal strip from being subjected to strong tensile force, which would cause the metal strip to be in a tight state and result in excessive tension. When the speed fluctuates, the loose metal strip can absorb the fluctuations through its own slack, such as temporary stretching or shortening, avoiding sudden tension changes and ensuring that the metal strip has a stable speed and tension.

[0014] The present invention has the following beneficial effects: (1) When using this invention, the operator connects the cable to be covered with the traction device, then pulls the metal strip on the metal strip drum through the gap between the roller frame one and the roller frame two, and then wraps the metal strip around the surface of the cable. The operator rotates the extrusion sleeve counterclockwise, and the extrusion assembly makes the rotating ring contact the top of the roller frame two. Then, the motor is started to drive the pulley group to rotate, and the rotating disk rotates, so that the metal strip covers the cable. When the roller frame two loosens, the rotating ring will be lifted. When the fixed plate rotates, the pressing assembly will push the rotating ring to rotate counterclockwise, and push the roller frame two to extrude the metal strip again, so that the metal strip maintains sufficient tension. This effectively prevents the metal strip from being pulled and vibrating frequently, which would cause the roller frame two to separate from the metal strip, resulting in a decrease in the tension of the metal strip and affecting the tight coverage of the cable by the metal strip.

[0015] (2) When the metal strip is pulled through the roller frame 1 and roller frame 2, the metal strip will come into contact with the extrusion roller, and the extrusion roller will extrude the metal strip. When the spring sliding frame descends, it will drive the piston rod to descend. Gas will be continuously injected into the closed sleeve through the reciprocating assembly, so that the gas in the closed sleeve is in a high-pressure state. When the vibration force generated by the metal strip is large, it will be transmitted to the extrusion roller. The gas in the closed sleeve will be extruded through the throttling orifice. Since the throttling orifice is small, the gas discharge speed is slow, which slows down the movement speed of the fixed frame, absorbs the vibration of the metal strip, and reduces the vibration amplitude of the metal strip.

[0016] (3) When the spring sliding frame descends, the connecting rod will descend, pushing the connecting rod to move. The connecting rod will rotate around the center of the extrusion roller, and the connecting rod will push the extrusion roller to rotate. When the extrusion roller rotates, the metal strip will be conveyed to slide downward, so that the metal strip above the roller frame one and roller frame two is in a loose state, forming a buffer section. This effectively prevents the metal strip from being subjected to strong tension, which would cause the metal strip to be in a tight state and result in excessive tension. When the speed fluctuates, the loose metal strip can absorb the fluctuation through its own slack, such as a brief extension or shortening, to avoid sudden tension changes and ensure that the metal strip has a stable speed and tension.

[0017] (4) When the tension of the metal strip needs to be adjusted, the screw rod is rotated clockwise to separate from the spring arc block, so that the spring arc block's rebound force is released and the spring arc block is separated from the rotating ring. Then, the extrusion sleeve is rotated to push the roller frame two toward or away from the metal strip, and the extrusion force on the metal strip is adjusted. After the adjustment is completed, the rotating ring is made to fit against the top of the roller frame two. The spring arc block is rotated again to extrude the rotating ring. The rotating ring can rotate freely on the inner wall of the extrusion sleeve, so that the rotating ring can fit against the top of the roller frame two, effectively preventing the position of the rotating ring from changing when adjusting the tension of the metal strip, which would affect the extrusion of the rotating ring by the spring sliding frame.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-Figure 5 This invention relates to a cable outer sheath winding device, comprising: The covering mechanism 1 has a drive assembly 11 installed on its side wall and a winding assembly 12 rotatably installed on its inner wall. The winding assembly 12 is used to wind the armor layer onto the surface of the cable. Control mechanism 2, installed on the side wall of winding assembly 12, is used to control the tension of the metal strip; and The buffer mechanism 3 is located on the side wall of the winding assembly 12 and is used to reduce the vibration amplitude of the metal strip. When wrapping the cable with the armor layer, the cable passes through the center of the wrapping assembly 12, and then the drive assembly 11 rotates the wrapping assembly 12 to wrap the armor layer around the cable surface. Then, the control mechanism 2 controls the tension of the armor layer to effectively prevent the metal strip from vibrating frequently when it is being pulled, which would reduce the tension of the metal strip and affect the tight wrapping of the cable by the metal strip. Finally, the buffer mechanism 3 reduces the vibration amplitude of the metal strip.

[0023] The covering mechanism 1 includes a support platform 13; The drive assembly 11 is fixedly installed on the side wall of the support platform 13 and is used to drive the winding assembly 12 to rotate. The outer wall of the winding assembly 12 is rotatably mounted on the inner wall of the support platform 13 for winding an armor layer onto the surface of the cable. The process involves inserting the cable to be wrapped with the armor layer into the winding assembly 12, then connecting the cable to the traction device, moving the cable by pulling it, and finally rotating the winding assembly 12 by the drive assembly 11 to wrap the cable surface with the armor layer.

[0024] The drive assembly 11 includes a pulley group 111 disposed on the side wall of the support platform 13, and a motor 112 is fixedly connected to the side wall of the support platform 13. The output end of the motor 112 is fixedly connected to the side wall of the pulley assembly 111, and a protective cover 113 is fixedly connected to the side of the support platform 13 away from the pulley assembly 111. The winding assembly 12 includes a rotating disk 121 rotatably connected to the inner wall of the support platform 13. The outer wall of the rotating disk 121 is fixedly connected to the inner wall of the pulley assembly 111. A connecting ring 122 is fixedly connected to the side wall of the rotating disk 121. A fixing plate 123 is fixedly connected to the inner wall of the connecting ring 122, and two metal strip cylinders 124 are rotatably connected to the inner wall of the fixing plate 123.

[0025] Control mechanism 2 includes: The extrusion assembly 21 is fixedly disposed on the side wall of the fixed plate 123 and is used to extrude metal strips; Pressing component 22 is fixedly installed on the side wall of the fixed plate 123 and is used to press the squeezing component 21; When the winding assembly 12 wraps the cable surface with the covering layer, the extrusion assembly 21 extrudes the metal strip to control the tension of the metal strip. When the tension weakens, the pressing assembly 22 presses the extrusion assembly 21 to increase the tension again, effectively preventing the metal strip from vibrating frequently, causing the extrusion assembly 21 to separate from the metal strip, resulting in a decrease in the tension of the metal strip and affecting the tight wrapping of the cable by the metal strip.

[0026] Buffer mechanism 3 includes: Reciprocating assembly 31 is fixedly installed on the side wall of the fixed plate 123 and is used to reciprocate and compress gas. The damping component 32 is slidably disposed on the side wall of the fixed plate 123 to reduce the vibration amplitude of the metal strip. When the pressing component 22 squeezes the pressing component 21, the reciprocating component 31 will squeeze the gas, allowing the gas to enter the damping component 32. When the damping component 32 is affected by the vibration force of the metal belt, it will absorb the vibration of the metal belt and reduce the vibration amplitude of the metal belt.

[0027] Example 2, please refer to Figures 1-11 The present invention is a cable outer sheath winding device. Based on Example 1, the extrusion assembly 21 includes two roller frames 211 fixedly connected to the side wall of the fixed plate 123, two roller frames 212 slidably connected to the side wall of the fixed plate 123, and threaded rods 213 rotatably connected to the inner walls of the two roller frames 212. Both threaded rods 213 are fixedly connected to the side walls of the two threaded rods 214, and three spring arc blocks 216 are slidably connected to the inner walls of the two threaded rods 214. Rotating rings 215 are rotatably connected to the inner walls of both extrusion sleeves 214, and the outer walls of both threaded rods 1 213 are threadedly connected to the inner walls of the fixing plate 123. Threaded rods 217 are threadedly connected to the inner walls of both extrusion sleeves 214. When the operator pulls the metal strip on the metal strip drum 124, the metal strip passes between the roller frame 211 and the roller frame 212. The operator rotates the extrusion sleeve 214 counterclockwise, which drives the threaded rod 213 to rotate. Figure 10 As shown, this will push the roller frame 212 towards the metal strip, squeezing the metal strip and causing it to undergo slight elastic deformation, increasing the tension of the metal strip. After the tension is adjusted, by rotating the rotating ring 215, the rotating ring 215 contacts the top of the roller frame 212. Then, the threaded rod 217 is rotated counterclockwise, causing the threaded rod 217 to move towards the threaded rod 213. The threaded rod 217 will then squeeze the spring arc block 216 towards the rotating ring 215, causing the spring arc block 216 to squeeze the rotating ring 215. At the same time, the spring arc block 216 accumulates rebound force. Then, the motor 112 is started to drive the pulley assembly 111 to rotate, which in turn causes the rotating disk 121 to rotate, making the connecting ring 122 and the fixed plate 123 rotate, and causing the metal strip drum 124 to rotate around the center of the rotating disk 121. At the same time, the traction device is started to pull the cable to move. During the rotation of the fixed plate 123, the metal strip on the metal strip drum 124 will be pulled and wrapped around the cable to form a coating layer.

[0028] The pressing component 22 includes two limiting blocks 223 fixedly connected to the side wall of the fixing plate 123, a concave-convex ring 221 fixedly connected to the inner wall of the protective cover 113, and two spring sliding brackets 222 provided on the side wall of the fixing plate 123. The outer walls of the two spring sliding brackets 222 are slidably connected to the inner walls of the two limiting blocks 223. During the continuous stretching of the metal strip, vibrations occur, causing frequent vibrations to the roller frame 212. This leads to the loosening of the threaded rod 213, which rotates clockwise. Because the spring arc block 216 presses against the rotating ring 215, the rotation of the compression sleeve 214, via the spring arc block 216, causes the rotating ring 215 to rotate, resulting in the left side of the rotating ring 215 tilting upwards. Figure 10 As shown, when the fixed plate 123 rotates, it will drive the spring sliding frame 222 to rotate. When the spring sliding frame 222 moves to the protruding position of the concave-convex ring 221, the spring sliding frame 222 will be squeezed, causing it to accumulate rebound force. When the spring sliding frame 222 is compressed, it will move towards the rotating ring 215. When the rotating ring 215 is raised, the spring sliding frame 222 will descend and contact the rotating ring 215, pushing the rotating ring 215 to rotate counterclockwise, causing the threaded rod 213 to rotate, pushing the roller frame 212 to compress the metal strip again, so that the metal strip maintains sufficient tension, effectively preventing the metal strip from vibrating frequently when being pulled, which would cause the roller frame 212 to separate from the metal strip, resulting in a decrease in the tension of the metal strip and affecting the tight wrapping of the cable by the metal strip.

[0029] The reciprocating assembly 31 includes two pneumatic sleeves 311 disposed on the side wall of the fixed plate 123, and a piston rod 312 is slidably connected to the inner wall of each of the two pneumatic sleeves 311. Both pneumatic sleeves 311 have air supply pipes 314 that are connected through to their inner walls. The side of each pneumatic sleeve 311 away from the extrusion sleeve 214 is fixedly connected to the side of each limiting block 223 that is close to the extrusion sleeve 214. One-way valves 315 are slidably connected to the inner walls of the two gas pipes 314. The side of the two piston rods 312 away from the extrusion sleeve 214 is fixedly connected to the side of the two spring sliding frames 222 close to the extrusion sleeve 214. Six air pressure holes 313 are opened on the inner wall of the air pressure sleeve 311. When the metal strip is pulled through the roller frame 211 and roller frame 212, the metal strip will come into contact with the extrusion roller 325, causing the extrusion roller 325 to extrude the metal strip. When the spring sliding frame 222 descends, it will drive the piston rod 312 to descend. When the piston rod 312 descends past the air pressure hole 313, it will extrude the gas in the air pressure sleeve 311. At this time, the extruded gas will be blocked by the one-way valve 315, so the gas pressure will increase. As the gas pressure increases, the high-pressure gas will push the one-way valve 315 to move, removing the obstruction to the gas. The high-pressure gas will then enter the closed sleeve 322. After the spring sliding frame 222 rotates and separates from the protruding position of the concave and convex ring 221; The spring-loaded sliding frame 222 will release its rebound force, causing it to return to its original position and allowing the piston rod 312 to rise. After the piston rod 312 returns to its original position, the air pressure port 313 will reconnect with the bottom of the piston rod 312, allowing external gas to enter the air pressure sleeve 311 until the spring-loaded sliding frame 222 is pressed down again, causing the piston rod 312 to squeeze gas into the closed sleeve 322 again, continuously injecting gas into the closed sleeve 322, so that the gas in the closed sleeve 322 is in a high-pressure state.

[0030] The mitigation assembly 32 includes two fixed brackets 321 slidably connected to the side wall of the fixed plate 123. A spring piston block 323 is fixedly connected to the side wall of each of the two fixed brackets 321. Two sealing sleeves 322 are fixedly connected to the side wall of the fixed plate 123. The inner wall of each of the two sealing sleeves 322 is slidably connected to the outer wall of each of the two spring piston blocks 323. A throttling orifice 324 is provided on the inner wall of each of the two sealing sleeves 322. The inner wall of each of the two sealing sleeves 322 is connected through to the outer wall of each of the two gas pipes 314. When the vibration force generated by the metal strip is large, it is transmitted to the extrusion roller 325, which will push the fixed frame 321 to move towards the pneumatic sleeve 311. The fixed frame 321 will drive the spring piston block 323 to squeeze the gas in the closed sleeve 322, so that the spring piston block 323 accumulates the rebound force. At this time, the squeezed gas will be ejected through the throttle hole 324. Since the throttle hole 324 is small, the gas discharge speed is slow, which slows down the moving speed of the fixed frame 321, absorbs the vibration of the metal strip, and reduces the vibration amplitude of the metal strip.

[0031] The damping assembly 32 also includes a compression roller 325 rotatably connected to the inner wall of the fixed frame 321, a connecting rod 326 fixedly connected to the side wall of each of the two spring sliding frames 222, a connecting rod 327 rotatably connected to the side wall of each of the two connecting rods 326, and the side wall of each of the two compression rollers 325 rotatably connected to the inner wall of each of the two connecting rods 327. When the spring sliding frame 222 descends, it drives the connecting rod 326 to descend, pushing the connecting rod 327 to move. The connecting rod 327 rotates around the center of the extrusion roller 325. When the connecting rod 326 moves up and down with the spring sliding frame 222, the connecting rod 327 pushes the extrusion roller 325 to rotate. Since the extrusion roller 325 extrudes the metal strip, when the extrusion roller 325 rotates, it will transport the metal strip to slide downwards, so that the metal strip above the roller frame 1 211 and roller frame 2 212 is in a loose state, forming a buffer section. This effectively prevents the metal strip cylinder 124 from being subjected to strong tension, which would cause the metal strip to be in a tight state and result in excessive tension. When the speed fluctuates, the loose metal strip can absorb the fluctuation through its own slack, such as a brief stretching or shortening, to avoid sudden tension changes and ensure that the metal strip has a stable speed and tension.

[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When using this invention, the operator passes the cable to be wrapped through the center of the rotating disk 121 and the fixed plate 123, then connects the cable to the traction device, and then pulls the metal strip on the metal strip drum 124 through the roller frame 1 211 and the roller frame 2 212. Then, the metal strip is wrapped around the surface of the cable. After the wrapping is completed; The operator rotates the extrusion sleeve 214 counterclockwise, which in turn rotates the threaded rod 213, for example: Figure 10 As shown, this will push the roller frame 212 towards the metal strip, squeezing the metal strip and causing it to undergo slight elastic deformation, increasing the tension of the metal strip. After the tension is adjusted, by rotating the rotating ring 215, the rotating ring 215 contacts the top of the roller frame 212. Then, the threaded rod 217 is rotated counterclockwise, causing the threaded rod 217 to move towards the threaded rod 213. The threaded rod 217 will then squeeze the spring arc block 216 towards the rotating ring 215, causing the spring arc block 216 to squeeze the rotating ring 215. At the same time, the spring arc block 216 accumulates rebound force. Then, the starting motor 112 drives the pulley assembly 111 to rotate, which in turn rotates the rotating disk 121, causing the connecting ring 122 and the fixed plate 123 to rotate. This causes the metal strip drum 124 to rotate around the center of the rotating disk 121. Simultaneously, the traction device is activated to pull the cable. During the rotation of the fixed plate 123, the metal strip on the metal strip drum 124 is stretched and wraps around the cable, forming a coating layer. As the metal strip is continuously stretched, vibration is generated, causing the roller frame 212 to be frequently vibrated. When the threaded rod 213 loosens, it will rotate clockwise. Because the spring arc block 216 presses the rotating ring 215, when the compression sleeve 214 rotates, the spring arc block 216 will drive the rotating ring 215 to rotate, causing the left side of the rotating ring 215 to tilt up, as shown below. Figure 10 As shown, when the fixed plate 123 rotates, it will drive the spring sliding frame 222 to rotate. When the spring sliding frame 222 moves to the protruding position of the concave-convex ring 221, the spring sliding frame 222 will be squeezed, causing it to accumulate rebound force. When the spring sliding frame 222 is compressed, it will move towards the rotating ring 215. When the rotating ring 215 is raised, the spring sliding frame 222 will descend and contact the rotating ring 215, pushing the rotating ring 215 to rotate counterclockwise, causing the threaded rod 213 to rotate, pushing the roller frame 212 to compress the metal strip again, so that the metal strip maintains sufficient tension, effectively preventing the metal strip from vibrating frequently when being pulled, causing the roller frame 212 to separate from the metal strip, resulting in a decrease in the tension of the metal strip, which would affect the tight wrapping of the cable by the metal strip; Secondly, when the metal strip is pulled through between the roller frame 1 211 and the roller frame 212, the metal strip will come into contact with the extrusion roller 325, causing the extrusion roller 325 to extrude the metal strip. When the spring sliding frame 222 descends, it will drive the piston rod 312 to descend. When the piston rod 312 descends past the air pressure hole 313, it will extrude the gas in the air pressure sleeve 311. At this time, the extruded gas will be blocked by the one-way valve 315, so the gas pressure will increase. As the gas pressure increases, the high-pressure gas will push the one-way valve 315 to move, removing the obstruction to the gas. The high-pressure gas will then enter the closed sleeve 322. After the spring sliding frame 222 rotates and separates from the protruding position of the concave and convex ring 221; The spring sliding frame 222 will release its rebound force, causing it to return to its original position and allowing the piston rod 312 to rise. After the piston rod 312 returns to its original position, the air pressure hole 313 will reconnect with the bottom of the piston rod 312, allowing external gas to enter the air pressure sleeve 311 until the spring sliding frame 222 is pressed down again, causing the piston rod 312 to squeeze the gas into the closed sleeve 322 again, continuously injecting gas into the closed sleeve 322, keeping the gas in the closed sleeve 322 under high pressure. When the vibration force generated by the metal strip is large, it will be transmitted to the extrusion roller 325, pushing the fixed frame 321 to move towards the air pressure sleeve 311. The fixed frame 321 will drive the spring piston block 323 to squeeze the gas in the closed sleeve 322, causing the spring piston block 323 to accumulate rebound force. At this time, the squeezed gas will be ejected through the throttle hole 324. Since the throttle hole 324 is small, the gas discharge speed is slow, which slows down the movement speed of the fixed frame 321, absorbs the vibration of the metal strip, and reduces the vibration amplitude of the metal strip. When the gas is ejected through the throttle hole 324, the vibration energy is directly released to the outside in the form of gas kinetic energy, forming an energy leakage, which avoids the accumulation of energy in the closed sleeve 322 and can quickly attenuate the vibration amplitude. Compared with the high-pressure gas in the closed sleeve 322, when the gas is squeezed by the spring piston block 323, the gas circulates on both sides of the spring piston block 323. The energy is converted repeatedly in the form of pressure fluctuation in the closed space, which is difficult to be effectively discharged and easily leads to vibration rebound. Secondly, when the spring sliding frame 222 descends, it will drive the connecting rod 326 to descend, pushing the connecting rod 327 to move. The connecting rod 327 will rotate around the center of the extrusion roller 325. When the connecting rod 326 moves up and down with the spring sliding frame 222, the connecting rod 327 will push the extrusion roller 325 to rotate. Since the extrusion roller 325 will extrude the metal strip, when the extrusion roller 325 rotates, it will convey the metal strip to slide downward, so that the metal strip above the roller frame 1 211 and roller frame 2 212 is in a loose state, forming a buffer section. This effectively prevents the metal strip cylinder 124 from being subjected to strong tension, which would cause the metal strip to be in a tight state and cause excessive tension. When the speed fluctuates, the loose metal strip can absorb the fluctuation through its own slack, such as a brief extension or shortening, to avoid sudden tension changes and ensure that the metal strip has a stable speed and tension. Secondly, when it is necessary to adjust the tension of the metal strip, the threaded rod 217 is rotated clockwise to separate from the spring arc block 216, releasing the rebound force of the spring arc block 216 and separating the spring arc block 216 from the rotating ring 215. Then, the compression sleeve 214 is rotated to push the roller frame 212 towards or away from the metal strip, adjusting the compression force on the metal strip. After adjustment, the rotating ring 215 is brought into contact with the top of the roller frame 212. The spring arc block 216 is rotated again to compress the rotating ring 215. The rotating ring 215 can rotate freely on the inner wall of the compression sleeve 214, allowing it to contact the top of the roller frame 212. This effectively prevents the position of the rotating ring 215 from changing when adjusting the metal strip tension, thus affecting the compression of the rotating ring 215 by the spring sliding frame 222.
