Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable production equipment, in particular to a cable outer covering layer winding device. BACKGROUND

[0002] The cable outer covering layer (also known as the sheath) is the outermost protective barrier in the cable structure, and its core function is to resist the damage of the external environment to the internal conductor and insulation layer. The covering layer achieves basic protection such as waterproofing, corrosion resistance, and mechanical impact resistance through physical isolation. The cable outer covering layer winding device is a special mechanical device used in cable manufacturing to accurately, continuously, and tightly cover one or more layers of strip-shaped material outside the cable core (conductor + insulation layer + possible shielding layer).

[0003] In the process of winding the armored layer on the cable outer covering layer, the metal strip is often wound on the surface of the cable in a spiral lap joint manner. In this process, the metal strip needs to maintain appropriate tension. However, in actual operation, the metal strip is prone to oscillation when being pulled, which may cause the metal strip to vibrate. This vibration may cause the guide roller used to extrude the metal strip to loosen, thereby causing the tension of the metal strip to decrease, which will affect the adhesion of the metal strip to the cable and make it difficult to form a stable and tight covering. SUMMARY

[0004] To solve the above technical problems, the present application provides a cable outer covering layer winding device, comprising:

[0005] A covering mechanism is installed on the side wall of the covering mechanism, and a driving assembly is installed on the inner wall of the covering mechanism. The winding assembly is used to wind the armored layer on the surface of the cable.

[0006] A control mechanism is installed on the side wall of the winding assembly to control the tension of the metal strip.

[0007] A buffer mechanism is located on the side wall of the winding assembly to reduce the vibration amplitude of the metal strip.

[0008] When winding the armored layer on the cable, the cable is passed through the center of the winding assembly, and then the winding assembly is rotated by the driving assembly to wind the armored layer on the surface of the cable. Then, the control mechanism controls the tension of the armored layer to effectively prevent the metal strip from vibrating frequently when being pulled, causing the tension of the metal strip to decrease and affecting the tight covering of the metal strip on the cable. Finally, the buffer mechanism reduces the vibration amplitude of the metal strip.

[0009] Preferably, the covering mechanism includes a support table.

[0010] The side wall of the driving assembly is fixedly arranged on the side wall of the support table to drive the rotation of the winding assembly.

[0011] The outer wall of the winding assembly is rotatably arranged at the inner wall of the support table, and is used for winding the armored layer on the surface of the cable;

[0012] The cable to be wound with the armored layer is inserted into the winding assembly, then the cable is connected with the traction device, the cable is moved by the traction device, and finally the armored layer is wound on the surface of the cable by rotating the winding assembly.

[0013] Preferably, the driving assembly comprises a belt pulley group arranged at the side wall of the support table, and a motor fixedly connected to the side wall of the support table;

[0014] The output end of the motor is fixedly connected to the side wall of the belt pulley group, and a protective cover is fixedly connected to the side away from the belt pulley group of the support table;

[0015] The winding assembly comprises a rotating disc rotatably connected to the inner wall of the support table, the outer wall of the rotating disc is fixedly connected to the inner wall of the belt pulley group, and the side wall of the rotating disc is fixedly connected with a connecting ring;

[0016] The inner wall of the connecting ring is fixedly connected with a fixed plate, and the inner wall of the fixed plate is rotatably connected with two metal band cylinders.

[0017] Preferably, the control mechanism comprises:

[0018] An extrusion assembly is fixedly arranged at the side wall of the fixed plate, and is used for extruding the metal band;

[0019] A pressing assembly is fixedly arranged at the side wall of the fixed plate, and is used for pressing the extrusion assembly;

[0020] When the winding assembly winds the armored layer on the surface of the cable, the metal band is extruded by the extrusion assembly to control the tension of the metal band, when the tension is weakened, the extrusion assembly is pressed by the pressing assembly to increase the tension again, effectively preventing the metal band from frequent vibration, causing the separation of the drum frame two and the metal band, resulting in the decrease of the tension of the metal band, and affecting the tight covering of the metal band on the cable.

[0021] Preferably, the buffer mechanism comprises:

[0022] A reciprocating assembly is fixedly arranged at the side wall of the fixed plate, and is used for reciprocatingly extruding gas;

[0023] A slowing assembly is slidingly connected to the side wall of the fixed plate, and is used for reducing the vibration amplitude of the metal band;

[0024] When the pressing assembly extrudes the extrusion assembly, the reciprocating assembly extrudes the gas, and the gas enters the slowing assembly, when the slowing assembly is affected by the vibration force of the metal band and moves, the vibration of the metal band is absorbed, and the vibration amplitude of the metal band is reduced.

[0025] Preferably, the extrusion assembly comprises two roller frames one fixedly connected at the side wall of the fixed plate, two roller frames two slidingly connected at the side wall of the fixed plate, the inner wall of the two roller frames two are both rotationally connected with a threaded rod one;

[0026] The side wall of the two threaded rods one are both fixedly connected with an extrusion sleeve, the inner wall of the two extrusion sleeves are both slidingly connected with three spring arc blocks;

[0027] The inner wall of the two extrusion sleeves are both rotationally connected with a rotating ring, the outer wall of the two threaded rods one are both threadedly connected with the inner wall of the fixed plate, the inner wall of the two extrusion sleeves are both threadedly connected with a threaded rod two;

[0028] When the operator pulls the metal belt on the metal belt cylinder, the metal belt passes between the roller frame one and the roller frame two, the operator rotates the extrusion sleeve counterclockwise to drive the threaded rod one to rotate, which pushes the roller frame two to move towards the metal belt direction, extruding the metal belt to produce slight elastic deformation and increase the tension of the metal belt. When the tension adjustment is completed, rotate the rotating ring to make it contact with the top of the roller frame two, then rotate the threaded rod two counterclockwise to make it move towards the threaded rod one direction, which extrudes the spring arc block to move towards the rotating ring direction, so that the spring arc block extrudes the rotating ring and accumulates the elastic force at the same time;

[0029] Then, start the motor to drive the pulley set to rotate, rotate the rotating disc through the pulley set, make the connecting ring rotate with the fixed plate, and make the metal belt cylinder rotate around the center of the rotating disc. At the same time, start the traction device to pull the cable to move. During the rotation of the fixed plate, the metal belt on the metal belt cylinder will be pulled and wrapped on the cable to form a wrapping layer.

[0030] Preferably, the pressing assembly comprises two limiting blocks fixedly connected at the side wall of the fixed plate, a concave-convex ring fixedly connected at the inner wall of the protective cover, and two spring sliding frames arranged at the side wall of the fixed plate and slidingly connected with the inner wall of the two limiting blocks;

[0031] When the metal belt is continuously pulled and vibrates, the roller frame two will be affected by frequent vibration, which will cause the threaded rod one to rotate clockwise when it loosens. Since the spring arc block extrudes the rotating ring, the rotating ring will rotate when the extrusion sleeve rotates, which will make the left side of the rotating ring rise. When the fixed plate rotates, it will drive the spring sliding frame to rotate. When the spring sliding frame moves to the convex position of the concave-convex ring, it will be extruded to accumulate elastic force;

[0032] When the spring sliding frame is pressed, it will move towards the rotating ring direction. When the rotating ring is raised, the spring sliding frame will be lowered to contact the rotating ring, push the rotating ring to rotate counterclockwise, rotate the threaded rod, push the roller frame two to press the metal strip again, so that the metal strip maintains sufficient tension, effectively prevents the metal strip from being pulled and vibrates frequently, causes the roller frame two to separate from the metal strip, reduces the tension of the metal strip, and affects the tight wrapping of the metal strip on the cable.

[0033] Preferably, the reciprocating assembly comprises two air pressure sleeves arranged at the side wall of the fixed plate, and the inner wall of each air pressure sleeve is slidably connected with a piston rod;

[0034] The inner wall of each air pressure sleeve is throughly connected with a gas delivery pipe, and the side of each air pressure sleeve away from the pressing sleeve is fixedly connected with the side of each limiting block close to the pressing sleeve;

[0035] The inner wall of each gas delivery pipe is slidably connected with a one-way valve, and the side of each piston rod away from the pressing sleeve is fixedly connected with the side of each spring sliding frame close to the pressing sleeve. Six air pressure holes are formed in the inner wall of the air pressure sleeve;

[0036] When the metal strip is pulled to pass between the roller frame one and the roller frame two, the metal strip will contact the pressing roller to make the pressing roller press the metal strip. When the spring sliding frame is lowered, the piston rod will be lowered. When the piston rod is lowered and passes through the air pressure hole, the gas in the air pressure sleeve will be pressed. At this time, the pressed gas will be blocked by the one-way valve, so the gas pressure will rise. With the increase of air pressure, the high-pressure gas will push the one-way valve to move, cancel the blockage of the gas, and the high-pressure gas will enter the closed sleeve. After the spring sliding frame is separated from the convex position of the convex-concave ring during the rotating process of the spring sliding frame;

[0037] The rebound force of the spring sliding frame is released, so that it returns to the original position, and the piston rod rises. When the piston rod returns to the original position, the air pressure hole will be in communication with the bottom of the piston rod again, so that the external gas enters the air pressure sleeve. Until the spring sliding frame is pressed again and lowered, the piston rod presses the gas into the closed sleeve again, continuously injects the gas into the closed sleeve, and keeps the gas in the closed sleeve in a high-pressure state.

[0038] Preferably, the slowing down assembly comprises two fixed frames slidably connected at the side wall of the fixed plate, and the side wall of each fixed frame is fixedly connected with a spring piston block. The side wall of the fixed plate is fixedly connected with two closed sleeves, the inner wall of each closed sleeve is slidably connected with the outer wall of each spring piston block, the inner wall of each closed sleeve is provided with a throttling hole, and the inner wall of each closed sleeve is throughly connected with the outer wall of each gas delivery pipe.

[0039] When the vibration force generated by the metal belt is large and is transmitted to the extrusion roller, the fixed frame is pushed to move towards the air pressure sleeve, the fixed frame drives the spring piston block to extrude the gas in the closed sleeve, the spring piston block accumulates the elastic force, at this time, the extruded gas is sprayed through the throttle hole, because the throttle hole is small, the gas is slowly discharged, the moving speed of the fixed frame is slowed down, the vibration of the metal belt is absorbed, and the vibration amplitude of the metal belt is reduced.

[0040] Preferably, the damping assembly further comprises an extrusion roller rotatably connected to the inner wall of the fixed frame, the side wall of each of the two spring sliding frames is fixedly connected with a connecting rod, and the side wall of each of the two connecting rods is rotatably connected with a connecting rod.

[0041] When the spring sliding frame descends, the connecting rod is driven to descend and move the connecting rod, and the connecting rod rotates around the center of the extrusion roller, when the connecting rod reciprocates up and down with the spring sliding frame, the connecting rod drives the extrusion roller to rotate, because the extrusion roller extrudes the metal belt, when the extrusion roller rotates, the metal belt is conveyed to slide downward, so that the metal belt above the roller frame one and the roller frame two is in a loose state, forming a buffer section, effectively preventing the metal belt from being in a tight state due to strong pulling force, causing excessive tension, and the buffer section of the metal belt can absorb fluctuations such as temporary elongation or shortening by its own relaxation amount when the speed fluctuates, avoiding sudden tension, and ensuring stable speed and tension of the metal belt.

[0042] The present application has the following advantages:

[0043] (1) When the present application is used, the operator connects the cable to be coated with the traction device, pulls the metal belt on the metal belt cylinder through the roller frame one and the roller frame two, and then winds the metal belt around the surface of the cable, the operator rotates the extrusion sleeve counterclockwise, the rotating ring contacts the top of the roller frame two through the extrusion assembly, and then the motor drives the pulley set to rotate, the rotating disc rotates, and the metal belt is coated on the cable, when the roller frame two is loose, the rotating ring is raised, when the fixed plate rotates, the rotating ring is pushed to rotate counterclockwise through the pressing assembly, the roller frame two extrudes the metal belt again, so that the metal belt maintains sufficient tension, effectively preventing the metal belt from vibrating frequently when being pulled, causing the roller frame two and the metal belt to separate, reducing the tension of the metal belt, and affecting the tight coating of the metal belt on the cable.

[0044] (2) The metal belt contacts the extrusion roller when being pulled through between the roller frame one and the roller frame two, so that the extrusion roller extrudes the metal belt. When the spring sliding frame descends, the piston rod is driven to descend, and the gas in the closed sleeve is continuously injected 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 belt is large and transmitted to the extrusion roller, the gas in the closed sleeve is extruded through the slowing down assembly, and at this time, the extruded gas is sprayed out through the throttle hole. Since the throttle hole is small, the gas is discharged slowly, the moving speed of the fixed frame is slowed down, the vibration of the metal belt is absorbed, and the vibration amplitude of the metal belt is reduced.

[0045] (3) When the spring sliding frame descends, the connecting rod is driven to descend and move, the connecting rod rotates around the center of the extrusion roller, and the connecting rod pushes the extrusion roller to rotate. When the extrusion roller rotates, the metal belt is conveyed to slide downward, so that the metal belt above the roller frame one and the roller frame two is in a loose state, a buffer section is formed, the tension of the metal belt is effectively prevented from being too large, and the metal belt is in a tight state. When the speed fluctuates, the loose metal belt can absorb the fluctuation through its own relaxation amount, such as temporary elongation or shortening, so as to avoid sudden change of tension and ensure stable speed and tension of the metal belt.

[0046] (4) When the tension of the metal belt needs to be adjusted, the spring arc block is separated from the threaded rod two by rotating the threaded rod two clockwise, the resilience of the spring arc block is released, the spring arc block is separated from the rotating ring, then the extrusion sleeve is rotated, the roller frame two is pushed to move towards or away from the metal belt, the extrusion force on the metal belt is adjusted, after the adjustment is completed, the rotating ring is attached to the top of the roller frame two, and the spring arc block is rotated again to extrude the rotating ring. The rotating ring can rotate freely in the inner wall of the extrusion sleeve, so that the rotating ring can be attached to the top of the roller frame two, and the position change of the rotating ring is effectively prevented when the tension of the metal belt is adjusted, which affects the extrusion of the spring sliding frame on the rotating ring.

[0078] When the winding assembly 12 winds the covering layer on the surface of the cable, the metal belt is extruded by the extrusion assembly 21 to control the tension of the metal belt, when the tension is weakened, the extrusion assembly 21 is pressed by the pressing assembly 22 to make the tension increase again, so that the metal belt is effectively prevented from frequent vibration, the extrusion assembly 21 is separated from the metal belt, the tension of the metal belt is reduced, and the metal belt tightly covers the cable.

[0079] The buffer mechanism 3 comprises:

[0080] The reciprocating assembly 31 is fixedly arranged at the side wall of the fixed plate 123 and used for reciprocating extruding the gas.

[0081] The damping assembly 32 is slidingly arranged at the side wall of the fixed plate 123 and used for reducing the vibration amplitude of the metal belt.

[0082] When the pressing assembly 22 extrudes the extrusion assembly 21, the reciprocating assembly 31 extrudes the gas, and the gas enters the damping assembly 32, when the damping assembly 32 is affected by the vibration force of the metal belt and moves, the vibration of the metal belt is absorbed, and the vibration amplitude of the metal belt is reduced.

[0083] Embodiment two, please refer to Figures 1-11 On the basis of example one, the extrusion assembly 21 comprises two roller frames one 211 fixedly connected with the side wall of the fixed plate 123, the side wall of the fixed plate 123 is slidingly connected with two roller frames two 212, and the inner wall of each of the two roller frames two 212 is rotatably connected with a threaded rod one 213.

[0084] The inner wall of each of the two extrusion sleeves 214 is slidably connected with three spring arc blocks 216.

[0085] The inner wall of each of the two extrusion sleeves 214 is rotatably connected with a rotating ring 215, the outer wall of each of the two threaded rods one 213 is threadedly connected with the inner wall of the fixed plate 123, and the inner wall of each of the two extrusion sleeves 214 is threadedly connected with a threaded rod two 217.

[0086] When the operator pulls the metal belt on the metal belt cylinder 124, the metal belt passes between the roller frame one 211 and the roller frame two 212, the operator rotates the extrusion sleeve 214 counterclockwise, drives the threaded rod one 213 to rotate, and pushes the roller frame two 212 to move towards the metal belt, extruding the metal belt to produce slight elastic deformation and increase the tension of the metal belt. Figure 10 When the tension adjustment is completed, the rotating ring 215 is brought into contact with the top of the roller frame two 212 by rotating the rotating ring 215, and then the threaded rod two 217 is rotated counterclockwise to move towards the threaded rod one 213, extruding the spring arc block 216 to move towards the rotating ring 215, extruding the spring arc block 216 to extrude the rotating ring 215, and accumulating the elastic force of the spring arc block 216.

[0087] Then, the motor 112 is started to drive the pulley set 111 to rotate, the pulley set 111 is used to rotate the rotating disc 121, the connecting ring 122 and the fixed plate 123 are rotated, the metal belt cylinder 124 is rotated around the center of the rotating disc 121, and the traction device is started to pull the cable to move.

[0088] The pressing assembly 22 includes two limiting blocks 223 fixedly connected to the side wall of the fixed plate 123, the inner wall of the protective cover 113 is fixedly connected with a concave-convex ring 221, the side wall of the fixed plate 123 is provided with two spring sliding frames 222, and the outer wall of each of the two spring sliding frames 222 is slidably connected with the inner wall of each of the two limiting blocks 223.

[0089] When the metal belt is continuously pulled and vibrates, the roller frame two 212 is frequently vibrated, the threaded rod one 213 is loosened, and the threaded rod one 213 is rotated clockwise, the spring arc block 216 extrudes the rotating ring 215, the rotating ring 215 is rotated by the spring arc block 216 when the extrusion sleeve 214 is rotated, and the left side of the rotating ring 215 is raised. Figure 10As shown, when the fixed plate 123 rotates, the spring sliding frame 222 is rotated, and when the spring sliding frame 222 moves to the convex position of the concave-convex ring 221, the spring sliding frame 222 is extruded to accumulate elastic force;

[0090] When the spring sliding frame 222 is extruded, it moves towards the rotating ring 215, and when the rotating ring 215 is raised, the spring sliding frame 222 is lowered to contact the rotating ring 215, which pushes the rotating ring 215 to rotate counterclockwise, rotates the threaded rod 213, pushes the drum frame two 212 to extrude the metal strip again, and keeps the metal strip with enough tension, effectively prevents the metal strip from being frequently vibrated when being pulled, causes the drum frame two 212 to separate from the metal strip, and reduces the tension of the metal strip, which affects the tight wrapping of the metal strip on the cable.

[0091] The reciprocating assembly 31 comprises two air pressure sleeves 311 arranged on the side wall of the fixed plate 123, and the inner wall of each air pressure sleeve 311 is slidably connected with a piston rod 312;

[0092] The inner wall of each air pressure sleeve 311 is throughly connected with a gas inlet pipe 314, and the side of each air pressure sleeve 311 away from the extrusion sleeve 214 is fixedly connected with the side of the limiting block 223 close to the extrusion sleeve 214;

[0093] The inner wall of each gas inlet pipe 314 is slidably connected with a one-way valve 315, and the side of each piston rod 312 away from the extrusion sleeve 214 is fixedly connected with the side of the spring sliding frame 222 close to the extrusion sleeve 214. The inner wall of the air pressure sleeve 311 is provided with six air pressure holes 313;

[0094] When the metal strip is pulled to pass between the drum frame one 211 and the drum frame two 212, the metal strip contacts the extrusion roller 325 to extrude the metal strip, and when the spring sliding frame 222 is lowered, the piston rod 312 is also lowered. When the piston rod 312 is lowered and passes through the air pressure hole 313, the gas in the air pressure sleeve 311 is extruded, and at this time, the extruded gas is blocked by the one-way valve 315, so the gas pressure is increased. With the increase of air pressure, the high-pressure gas pushes the one-way valve 315 to move, cancels the blockage of the gas, and the high-pressure gas enters the closed sleeve 322.

[0095] The rebound force of the spring sliding frame 222 is released, and the spring sliding frame 222 is reset, so that the piston rod 312 rises. When the piston rod 312 is reset, the gas pressure hole 313 is in communication with the bottom of the piston rod 312 again, so that external gas enters the gas pressure sleeve 311 until the spring sliding frame 222 is pressed again to descend, so that the piston rod 312 extrudes the gas into the closed sleeve 322 again, continuously injects the gas into the closed sleeve 322, and keeps the gas in the closed sleeve 322 in a high-pressure state.

[0096] The slowing assembly 32 comprises two fixed frames 321 slidably connected at the side walls of the fixed plate 123, and spring piston blocks 323 fixedly connected at the side walls of the two fixed frames 321. The fixed plate 123 is fixedly connected with two closed sleeves 322 at the side walls thereof. The inner walls of the two closed sleeves 322 are slidably connected with the outer walls of the two spring piston blocks 323. The inner walls of the two closed sleeves 322 are provided with throttling holes 324. The inner walls of the two closed sleeves 322 are throughly connected with the outer walls of two gas conveying pipes 314.

[0097] When the vibration force generated by the metal belt is large and is transmitted to the extrusion roller 325, the fixed frame 321 is pushed to move towards the gas pressure sleeve 311, the fixed frame 321 drives the spring piston block 323 to extrude the gas in the closed sleeve 322, so that the spring piston block 323 accumulates the rebound force. At this time, the extruded gas is sprayed out through the throttling hole 324. Since the throttling hole 324 is small, the gas is slowly discharged, which slows down the movement speed of the fixed frame 321, absorbs the vibration of the metal belt, and reduces the vibration amplitude of the metal belt.

[0098] The slowing assembly 32 further comprises an extrusion roller 325 rotatably connected at the inner wall of the fixed frame 321. The side walls of the two spring sliding frames 222 are fixedly connected with connecting rods 326. The side walls of the two connecting rods 326 are rotatably connected with connecting rods 327. The side walls of the two extrusion rollers 325 are rotatably connected with the inner walls of the two connecting rods 327.

[0099] When the spring sliding frame 222 descends, the connecting rod 326 is driven to descend, the connecting rod 327 is pushed to move, and the connecting rod 327 rotates around the center of the extrusion roller 325. When the connecting rod 326 reciprocates up and down with the spring sliding frame 222, the connecting rod 327 drives the extrusion roller 325 to rotate. Since the extrusion roller 325 extrudes the metal belt, when the extrusion roller 325 rotates, the metal belt is conveyed to slide downward, so that the metal belt above the roller frame one 211 and the roller frame two 212 is in a loose state, forming a buffer section, effectively preventing the metal belt cylinder 124 from being subjected to a strong pulling force, so that the metal belt is in a tight state, resulting in excessive tension. When the speed fluctuates, the loose metal belt can absorb the fluctuation by its own relaxation amount, such as temporary elongation or shortening, to avoid sudden change of tension, so as to ensure stable speed and tension of the metal belt.

[0100] 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.

[0101] 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;

[0102] 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.

[0103] 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.

[0104] When the spring sliding frame 222 is pressed, it will move towards the rotating ring 215. When the rotating ring 215 is raised, the spring sliding frame 222 will lower and contact the rotating ring 215, pushing the rotating ring 215 to rotate counterclockwise, rotating the threaded rod 213, pushing the drum frame two 212 to press the metal strip again, keeping enough tension on the metal strip, effectively preventing the metal strip from being pulled and vibrating frequently, causing the drum frame two 212 to separate from the metal strip, reducing the tension of the metal strip, and affecting the tight wrapping of the metal strip on the cable;

[0105] Secondly, when pulling the metal strip through the drum frame one 211 and the drum frame two 212, the metal strip will contact the extrusion roller 325, causing the extrusion roller 325 to extrude the metal strip. When the spring sliding frame 222 is lowered, it will lower the piston rod 312. When the piston rod 312 is lowered and passes through 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 rise. With the increase of air pressure, high-pressure gas will push the one-way valve 315 to move, canceling the blockage of the gas, and high-pressure gas will enter the closed sleeve 322. After the spring sliding frame 222 is separated from the convex position of the concave-convex ring 221 during rotation;

[0106] The spring sliding frame 222 will release the spring force and return to its original position, causing the piston rod 312 to rise. When the piston rod 312 returns to its original position, the air pressure hole 313 will again communicate 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 again and lowered, the piston rod 312 extrudes the gas into the closed sleeve 322 again, continuously injecting gas into the closed sleeve 322, keeping the gas in the closed sleeve 322 at high pressure. When the vibration force of the metal strip is large and is transmitted to the extrusion roller 325, it will push the fixed frame 321 towards the air pressure sleeve 311, causing the spring piston block 323 to extrude the gas in the closed sleeve 322, causing the spring piston block 323 to accumulate elastic force. At this time, the extruded gas will be ejected through the throttle hole 324. Because the throttle hole 324 is small, the gas is ejected at a slow speed, slowing down the movement speed of the fixed frame 321, absorbing the vibration of the metal strip, and reducing the vibration amplitude of the metal strip;

[0107] 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, avoiding the accumulation of energy in the closed sleeve 322, which can quickly attenuate the vibration amplitude. Compared with the high-pressure gas in the closed sleeve 322, which circulates on both sides of the spring piston block 323 when the spring piston block 323 extrudes the gas, the energy is converted in the form of pressure fluctuation in the closed space, which is difficult to effectively discharge and easy to cause vibration rebound;

[0108] Secondly, when the spring sliding frame 222 is lowered, the connecting rod 326 is lowered, the connecting rod 327 is pushed to move, the connecting rod 327 rotates around the center of the extrusion roller 325, when the connecting rod 326 reciprocates up and down with the spring sliding frame 222, the connecting rod 327 pushes the extrusion roller 325 to rotate, because the extrusion roller 325 extrudes the metal belt, when the extrusion roller 325 rotates, the metal belt is conveyed to slide downward, the metal belt above the roller frame one 211 and the roller frame two 212 is in a loose state, forming a buffer section, effectively preventing the metal belt cylinder 124 from being pulled too hard, causing the metal belt to be in a tight state, causing the tension to be too large, and the buffer section of the metal belt can absorb fluctuations by its own relaxation amount when the speed fluctuates, such as temporary elongation or shortening, avoiding sudden changes in tension, ensuring that the metal belt has stable speed and tension.

[0109] Secondly, when the tension of the metal belt needs to be adjusted, the threaded rod two 217 is rotated clockwise to separate from the spring arc block 216, the spring force of the spring arc block 216 is released, the spring arc block 216 is separated from the rotating ring 215, then the extrusion sleeve 214 is rotated, the roller frame two 212 is pushed to move towards or away from the metal belt, the extrusion force on the metal belt is adjusted, after the adjustment is completed, the rotating ring 215 is attached to the top of the roller frame two 212, the spring arc block 216 is rotated again to extrude the rotating ring 215, the rotating ring 215 can rotate freely in the inner wall of the extrusion sleeve 214, so that the rotating ring 215 can be attached to the top of the roller frame two 212, effectively preventing the position of the rotating ring 215 from changing when the tension of the metal belt is adjusted, affecting the extrusion of the spring sliding frame 222 on the rotating ring 215.
