Description

Technical Field

[0001] This application relates to the field of cable processing technology, and in particular to a traction device for cable bundling machines. Background Technology

[0002] Cable cabling is a crucial step in wire and cable manufacturing, and its quality directly determines the electrical and mechanical properties of the cable. In this process, the traction device is the core component of the cabling machine, responsible for providing stable and continuous traction force to the stranded cable cores, ensuring uniform cable pitch and a compact structure.

[0003] Currently, the industry commonly uses tracked traction machines for this task. Their working principle involves two sets of synchronously running tracks clamping the cable, relying on the friction between the track clamps and the cable surface to achieve traction. While this method can provide significant traction force, it has significant drawbacks in practical applications: because sufficient positive pressure must be applied to generate frictional traction, this clamping force can easily act directly on the cable itself. For cables with soft sheaths, large armor gaps, or loose structures, this can cause irreversible mechanical damage. Specifically, the cable is excessively compressed, changing from a round shape to an elliptical one, resulting in permanent indentations on the surface, and even causing deformation of the internal insulation core and damage to the shielding layer. This damage not only affects the product's appearance but also degrades the cable's electrical characteristics (such as characteristic impedance fluctuations and capacitance imbalances), creating potential long-term malfunctions and severely reducing product reliability and lifespan.

[0004] Therefore, there is an urgent need for a new type of traction device that can provide sufficient and stable traction force while completely avoiding squeezing damage to the cable surface. Summary of the Invention

[0011] In one possible implementation, the magnet switch mechanism includes: a first magnet rotatably mounted on the end of the second link away from the first link; a telescopic rod, one end of which is mounted on the side of the first magnet away from the second link; a second magnet, located at the other end of the telescopic rod; and the switch for the air pump is located within the inclined groove.

[0012] In one possible implementation, the pushing mechanism includes: a reciprocating mechanism and a driving mechanism; the reciprocating mechanism is provided in two sets, which are respectively located at the upper and lower parts of the mounting frame; the reciprocating mechanism includes: a horizontal bar located at the upper part of the mounting frame; multiple elastic levers, which are spaced apart at the bottom surfaces of both ends of the horizontal bar; two sets of first hinge blocks, which are respectively located at both ends of the surface of the horizontal bar; a swing arm, one end of which is hinged to the first hinge block; and a rotating shaft, one end of which is fixedly connected to the other end of the swing arm; the driving mechanism drives the rotating shaft.

[0013] In one possible implementation, the drive mechanism includes: a drive motor mounted on the upper part of the mounting frame; a first pulley located on the output shaft of the drive motor; four sets of second pulleys, each set mounted on a shaft of one of the two reciprocating mechanisms; the second pulleys are arranged in pairs, with one pair connected to the first pulley via a first synchronous belt and the other pair connected via a second synchronous belt; two sets of third pulleys, each set mounted on a pair of the second pulleys; and a redirecting pulley located on the outer wall of the mounting frame; the redirecting pulley is connected to the two sets of third pulleys via a third synchronous belt.

[0014] In one possible implementation, the drive mechanism further includes two sets of reciprocating drive components, which are used to drive the sector teeth of the separating mechanism and the closing mechanism to reciprocate. The reciprocating drive components include: a fourth pulley, disposed on the outer wall of the mounting frame; wherein the fourth pulley and the third pulley are drivenly connected by a fourth synchronous belt; an eccentric rod, one end of which rotates and is eccentrically connected to the outer wall of the fourth pulley; a rack, one end of which is rotatably connected to the other end of the eccentric rod; a reciprocating track, installed on the outer wall of the mounting frame, with the rack slidably disposed within the reciprocating track; and a gear, fixedly installed on the end of the rotating shaft away from the extension plate, the gear meshing with the rack.

[0015] In one possible implementation, the semi-cylindrical housing is provided with an inflation hole, one end of which is connected to the outer wall; a quick-connect valve is provided at one end of the inflation hole near the outer wall of the semi-cylindrical housing; wherein the inflation hole is connected to each of the elastic airbags, and each of the elastic airbags is provided with a solenoid valve between the inflation hole and the elastic airbag.

[0016] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: After multiple single-strand cables are twisted together by the twisting system, the twisted multi-strand cables are wrapped with tape by the wrapping system. The wrapped cables are placed at the entrance end of the traction zone. Two sets of symmetrically arranged semi-circular fixing components at the entrance end are driven and brought together by the closing mechanism, forming a cylindrical cavity between the two sets of semi-circular fixing components. The closed airbag fixing components are driven by the first track conveyor mechanism and the second track conveyor mechanism to move from the entrance end to the exit end in the traction zone. When the cable section is completely in the traction zone, the air pump works and inflates each elastic airbag through the pipeline. The elastic airbags inflate and abut against the outer wall of the cable. The inflated elastic airbags drive the cable to move in the traction zone through friction until the airbag fixing components reach the exit end of the traction zone. When the airbag fixing assembly reaches the outlet end, the separation mechanism works to separate the two sets of semi-circular fixing assemblies that are closed by the closing mechanism. The two sets of semi-circular fixing assemblies separate upward or downward along the horizontal plane. Before separation, the air in the elastic airbag is quickly emptied. The function of the separation mechanism is to lift the two sets of semi-circular fixing assemblies to both sides. The lifted semi-circular fixing assemblies are flush with the side of the first track conveyor that is away from the traction area. When the first track conveyor works, it will push the lifted semi-circular fixing assemblies to the entrance end of the traction area. The airbag fixing assembly is provided in multiple sets. By having multiple sets of airbag fixing assemblies move cyclically in the traction zone and on the side of the first track conveyor and the second track conveyor away from the traction zone, the cable can be tractioned.

[0017] The traction force is indirectly applied to the cable through the elastic airbag, realizing non-rigid contact between the traction device and the cable surface. This eliminates all the risks of surface damage caused by direct clamping of traditional tracked traction machines, such as indentations, deformation, and scratches. At the same time, after the elastic airbag is inflated, it can adaptively wrap around the entire circumference of the cable, providing evenly distributed pressure so that the traction force is evenly applied to the cable sheath, avoiding excessive local pressure that could damage the soft sheath material during traction. The operation of a single airbag fixing mechanism is intermittent, but the cyclical operation of multiple mechanisms makes the traction process of the entire cable continuous. The airbag wrapping method can prevent particles and debris from entering the contact surface when the tracked traction machine comes into direct contact with the cable, thus avoiding damage to the cable surface. Multiple elastic airbags are independently set, and each elastic airbag is connected to the air pump by a separate pipe. When some airbags age and cannot be inflated to the required volume, the remaining elastic airbags can still provide stable friction and pressure, making the replacement cost low, the equipment durable, and the maintenance simpler.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0023] Example 1 Please see Figures 1-9A traction device for a cable forming machine includes: multiple sets of airbag fixing mechanisms 100, and a first track conveying mechanism 200a and a second track conveying mechanism 200b disposed on both sides of the airbag fixing mechanism 100; wherein, the area between the first track conveying mechanism 200a and the second track conveying mechanism 200b is a traction zone 300; each airbag fixing mechanism 100 is composed of two symmetrical semi-circular fixing components 110, and the adjacent surfaces of the two semi-circular fixing components 110 are provided with elastic airbags 120, and the adjacent surfaces of the two sets of elastic airbags 120 are... Frictionally engages with the outer circumferential wall of the cable; a separation mechanism 400a, located at the outlet end of the traction zone 300, is used for each of the airbag fixing mechanisms 100 to separate after passing through the traction zone 300 and be placed on the side of the first track conveyor 200a and the second track conveyor 200b away from the traction zone 300; a closing mechanism 400b, located at the entrance end of the traction zone 300, is used for the two separated semi-circular fixing components 110 to engage with each other before entering the traction zone 300; each of the elastic airbags 120 is connected to an air pump pipe.

[0024] In the above embodiment, after multiple single-strand cables are twisted by the twisting system, the twisted multi-strand cables are wrapped with tape by the wrapping system. The wrapped cables are placed at the entrance end of the traction zone 300. Two sets of symmetrically arranged semi-circular fixing components 110 at the entrance end are driven and brought together by the closing mechanism 400b. A cylindrical cavity is formed between the two sets of semi-circular fixing components 110. The closed airbag fixing component is driven by the first track conveying mechanism 200a and the second track conveying mechanism 200b to move from the entrance end to the exit end in the traction zone 300. When the cable section is completely inside the traction zone 300, the air pump works and inflates each elastic airbag 120 through the pipeline. The elastic airbag 120 is inflated and expands, abutting against the outer wall of the cable. The inflated elastic airbag 120 drives the cable to move in the traction zone 300 through friction until the airbag fixing component reaches the exit end of the traction zone 300. When the airbag fixing assembly reaches the outlet end, the separation mechanism 400a operates to separate the two sets of semi-circular fixing assemblies 110 that are closed by the closing mechanism 400b. The two sets of semi-circular fixing assemblies 110 separate upward or downward along the horizontal plane. Before separation, the air in the elastic airbag 120 is quickly emptied. The function of the separation mechanism 400a is to lift the two sets of semi-circular fixing assemblies 110 to both sides. The lifted semi-circular fixing assemblies 110 are flush with the side of the first track conveyor 200a away from the traction zone 300. When the first track conveyor 200a operates, it will push the lifted semi-circular fixing assemblies 110 to the entrance end of the traction zone 300. The airbag fixing assembly is provided in multiple sets. The multiple sets of airbag fixing assemblies move cyclically in the traction zone 300 and on the side of the first track conveyor 200a and the second track conveyor 200b away from the traction zone 300 to achieve the traction effect on the cable.

[0025] The traction force is indirectly applied to the cable through the elastic airbag 120, realizing non-rigid contact between the traction device and the cable surface. This eliminates all surface damage risks such as indentations, deformation, and scratches caused by direct clamping of traditional tracked traction machines. At the same time, after the elastic airbag 120 is inflated, it can adaptively wrap around the entire circumference of the cable, providing uniformly distributed pressure so that the traction force is evenly applied to the cable sheath, avoiding excessive local pressure that could damage the soft sheath material during traction. The operation of a single airbag fixing mechanism 100 is intermittent, but the cyclical operation of multiple mechanisms makes the traction process of the entire cable continuous. The airbag wrapping method can prevent particles and debris from entering the contact surface when the tracked traction machine comes into direct contact with the cable, thus avoiding damage to the cable surface. Multiple elastic airbags 120 are independently set, and each elastic airbag 120 is connected to an air pump by a separate pipe. When some airbags age and cannot be inflated to the required volume, the remaining elastic airbags 120 can still provide stable friction and pressure, making the replacement cost low, the equipment durable, and the maintenance simpler.

[0026] Example 2 Please see Figures 1-9 Both the first track conveyor mechanism 200a and the second track conveyor mechanism 200b are composed of a track mechanism 210 and a telescopic coupling block 220. A plurality of telescopic coupling blocks 220 are provided, and each of these blocks is respectively installed on a track plate 230 of the track mechanism 210. Each telescopic coupling block 220 cooperates with the semi-circular fixing component 110 to drive the semi-circular fixing component 110 to move within the traction zone 300. The telescopic coupling block 220 includes: a mounting block 221, bolted to the track plate 230; a spring rod 222, one end of which is connected to the mounting block 221; and an anti-slip block 223, connected to the other end of the spring rod 222, which abuts against the semi-circular fixing component 110.

[0027] In the above embodiment, the first track conveyor mechanism 200a and the second track conveyor mechanism 200b are symmetrically spaced at the upper and lower parts of the horizontal plane. When the track mechanism 210 is working, it drives several track plates 230 linked together to move, and then drives the telescopic mating blocks 220 installed on them to move through the track plates 230. Each telescopic mating block 220 is tilted towards the surface of the semi-circular fixing component 110. The spring rod 222 of the telescopic mating block 220 is used to buffer when it contacts the semi-circular fixing component 110, and at the same time improves the problem of excessive pressing when rigidly connecting the semi-circular fixing component 110. The anti-sliding block 223 abuts against the surface of the semi-circular fixing component 110, and pushes the semi-circular fixing component 110 to move through the anti-sliding block 223.

[0028] Example 3 Please see Figures 1-9 The semi-circular fixing assembly 110 includes: a semi-cylindrical shell 111, with the opening surfaces of the semi-cylindrical shell 111 of the two sets of semi-circular fixing assemblies 110 arranged opposite each other; a flat plate 112, disposed on the side of the semi-cylindrical shell 111 away from its opening surface; two sets of sliding grooves 113, respectively disposed on the outer walls of both sides of the semi-cylindrical shell 111; two sets of sealing plates 114, respectively detachably installed at both ends of the semi-cylindrical shell 111; wherein, each of the elastic airbags 120 is evenly distributed on the inner wall of the opening surface of the semi-cylindrical shell 111; and several bosses 115, which are spaced apart along the length direction of the semi-cylindrical shell 111 on the outer wall of the semi-cylindrical shell 111, with limiting protrusions 116 and limiting grooves 117 respectively provided at the opening ends of the two sets of semi-cylindrical shells 111.

[0029] In the above embodiment, the elastic airbags 120 evenly distributed within the opening surface of the semi-cylindrical housing 111 engage with the cable through friction. When the two semi-cylindrical housings 111 are driven closer to each other by the closing mechanism 400b, a limiting protrusion 116 at the opening end of one semi-cylindrical housing 111 is embedded in a limiting groove 117 at the opening end of the other semi-cylindrical housing 111. Multiple limiting protrusions 116 and limiting grooves 117 are provided and spaced apart along the length direction of both ends of the opening of the semi-cylindrical housing 111. The limiting protrusions 116 are embedded in the limiting grooves 117. Inside 7, two semi-cylindrical housings 111 are fixed to prevent relative displacement of the two semi-cylindrical housings 111 during movement, which would cause local changes in the friction force on the cable and cause the cable to be scratched. A flat plate 112 is installed on the side of the semi-cylindrical housing 111 away from its opening. The side of the flat plate 112 away from the semi-cylindrical housing 111 is used to install each boss 115. The surface of each boss 115 is inclined towards the anti-sliding block 223 of the telescopic mating block 220, which is used to push the semi-cylindrical housing 111.

[0030] Example 4 Please see Figures 1-9 The first track conveyor 200a and the second track conveyor 200b are mounted on a mounting frame 500. The mounting frame 500 includes: multiple upright plates 510, which are respectively located on both sides of the first track conveyor 200a and the second track conveyor 200b; and a first guide rail 520 located on the side of the upright plates 510 near the first track conveyor 200a and the second track conveyor 200b.

[0031] In the above embodiment, the mounting frame 500 is used to install the first track conveyor 200a and the second track conveyor 200b. The upright plate 510 of the mounting frame 500 is used to slide and limit the semi-cylindrical housing 111 in the traction zone 300. When the two semi-cylindrical housings 111 are closed, in order to prevent them from shaking in the horizontal plane during movement, they are limited by the first guide rail 520 installed on the upright plate 510. When the semi-cylindrical housings 111 slide, they slide on the two first guide rails 520 through the sliding grooves 113 on both sides. When the two semi-cylindrical housings 111 enter the traction zone 300, the first guide rail 520 limits the two semi-cylindrical housings 111. Then the elastic airbag 120 is inflated, and the spring rod 222 pushes the two semi-cylindrical housings 111 to move closer to each other through the anti-sliding block 223. There is a gap between the sliding groove 113 and the first guide rail 520.

[0032] Example 5 Please see Figures 1-9Both the separating mechanism 400a and the closing mechanism 400b include a linkage mechanism 410, a guiding mechanism 420, and a pushing mechanism 430. Two sets of linkage mechanisms 410 and guiding mechanisms 420 are symmetrically arranged. The guiding mechanism 420 includes: a second guide rail 421, spaced apart on one side of the first guide rail 520; and a closing plate 422, located in the middle section of the second guide rail 421. The closing plate 422 is connected to the output end of the linkage mechanism 410. The linkage mechanism 410 includes: an extension plate 411, disposed on the end wall of the upright plate 510 and extending horizontally toward the second guide rail 421; a mounting shaft 412, disposed at one end of the extension plate 411 away from the upright plate 510; a sector tooth 413, the mounting end of which is fixedly connected to the circumferential outer wall of the mounting shaft 412, the tooth surfaces of the sector teeth 413 of the two sets of linkage mechanisms 410 meshing; and a first link 414, one end of which is fixedly connected to the mounting end of the sector tooth 413. Side; second connecting rod 415, one end of which is hinged to the other end of the first connecting rod 414; magnetic switch mechanism 416, rotatably disposed at the other end of the second connecting rod 415; inclined groove 417, disposed on the side wall of the semi-circular fixing assembly 110, the side of the magnetic switch mechanism 416 away from the second connecting rod 415 cooperating with the inclined groove 417; third connecting rod 418 and fourth connecting rod 419, parallel to one side of the sector tooth 413, the third connecting rod 418 and the first connecting rod 414 are connected to the first connecting rod 415. One end of the four-link 419 is hinged to the surface of the extension plate 411, and the other end is hinged to the surface of the closing plate 422; one end of the curved rod 4101 is located on the side of the sector tooth 413 near the third link 418, and the other end of the curved rod 4101 abuts against the side wall of the third link 418; wherein, one end of the third link 418 is sleeved on the circumferential outer wall of the mounting shaft 412, and a return torsion spring is installed between the third link 418 and the mounting shaft 412.

[0033] In the above embodiment, the linkage mechanism 410 is used to push the two sets of guide mechanisms 420 to open to both sides, so that the semi-circular fixing component 110 slidably disposed on the second guide rail 421 can be separated. When the linkage mechanism 410 is working, the sector teeth 413 are driven to rotate by the mounting shaft 412. Since the two sector teeth 413 mesh with each other, the two sector teeth 413 can synchronously drive the first link 414 to swing away from the upright plate 510. When the first link 414 swings, it pushes the second link 415 to work, so that the second link 415 moves away from the first link 414. When the position of one end of the rod 414 changes, the second connecting rod 415 drives the magnetic switch mechanism 416 to move away from the vertical plate 510 during operation. When the magnetic switch mechanism 416 reaches the inclined groove 417, it is embedded in the inclined groove 417. The magnetic switch mechanism 416 can push the semi-circular fixing component 110 to move away from the vertical plate 510, so that after the semi-circular fixing component 110 is separated from the first track conveyor mechanism 200a, it can slide completely into the second guide rail 421, so that the semi-circular fixing component 110 is completely separated from the first guide rail 520. The sector tooth 413 continues to rotate around the mounting shaft 412. When the first connecting rod 414 and the second connecting rod 415 are on the same straight line, the distance between the magnetic switch mechanism 416 and the sector tooth 413 is the largest. When the sector tooth 413 continues to rotate, the first connecting rod 414 pulls the second connecting rod 415 to move towards the vertical plate 510, so that the magnetic switch mechanism 416 installed at the end of the second connecting rod 415 disengages from the inclined groove 417, so that the magnetic switch mechanism 416 does not obstruct the two semi-circular fixed components 110 when they move away from each other. Subsequently, the crank rod 4101 installed on one side of the sector tooth 413 abuts against one side of the third link 418, thereby pushing the third link 418 to swing away from the vertical plate 510. The third link 418 and the fourth link 419 are arranged in parallel, so that the third link 418 and the fourth link 419 drive the closing plate 422 away from each other. During this process, the spring force of the reset torsion spring increases. When the two sets of semi-circular fixing components 110 are flush with the side of the first track conveyor 200a away from the traction area 300, the pushing mechanism 430 pushes the semi-circular fixing components 110 to the surface of the first track conveyor 200a, so that the first track conveyor 200a can transport the separated semi-circular fixing components 110 to the entrance end of the traction area 300. The fan-shaped teeth 413 of the closing mechanism 400b swing to drive its third link 418 and fourth link 419 to move the closing plates 422 away from each other, so that the second guide rail 421 installed on the closing plate 422 opens. When the semi-circular fixing component 110 is transported to the entrance end of the traction zone 300 by the first track conveyor mechanism 200a, the pushing mechanism 430 pushes the semi-circular fixing component 110 to slide into the second guide rail 421 of the closing mechanism 400b. The third link 418 and fourth link 419 swing in opposite directions to drive the two closing plates 422 to move closer to each other, so that the two semi-circular fixing components 110 located at the entrance end close into the traction zone 300. The reset torsion spring is used to drive the third link 418 and fourth link 419 to reset.

[0034] Example 6 Please see Figures 1-9 The magnet switch mechanism 416 includes: a first magnet 4161, rotatably mounted on the end of the second connecting rod 415 away from the first connecting rod 414; a telescopic rod 4162, one end of which is mounted on the side of the first magnet 4161 away from the second connecting rod 415; a second magnet 4163, located at the other end of the telescopic rod 4162; and the switch for the air pump is located in the inclined groove 417.

[0035] In the above embodiment, after the second magnet 4163 is embedded in the inclined groove 417, the switch of the air pump is pushed to turn on the power of the air pump. When the air pump is started, the elastic airbag 120 in the semi-circular fixing component 110 located at the outlet end of the traction zone 300 is evacuated, and the elastic airbag 120 at the inlet end is inflated. The side of the opening end of the inclined groove 417 near the vertical plate 510 and the side near the linkage mechanism 410 have slopes, so that the second magnet 4163 can be smoothly dislodged from the inclined groove 417 when it moves towards the vertical plate 510. The second magnet 4163 and the first magnet 4161 repel each other. The telescopic rod 4162 is used to move the second magnet 4163 towards the first magnet 4161 when it exits the inclined groove 417. The repulsive force between the second magnet 4163 and the first magnet 4161 pushes the second magnet 4163 to smoothly enter the inclined groove 417.

[0036] Example 7 Please see Figures 1-9The pushing mechanism 430 includes a reciprocating mechanism 431 and a driving mechanism 432. The reciprocating mechanism 431 has two sets, located at the upper and lower parts of the mounting frame 500 respectively. Each reciprocating mechanism 431 includes: a horizontal rod 4311 located at the upper part of the mounting frame 500; multiple elastic levers 4312, spaced apart at both ends of the bottom surface of the horizontal rod 4311; two sets of first hinge blocks 4313 located at both ends of the surface of the horizontal rod 4311; a swing rod 4314, one end of which is hinged to the first hinge block 4313; and a rotating shaft 4315, one end of which is fixedly connected to the other end of the swing rod 4314. The driving mechanism 432 drives the rotating shaft 4315.

[0037] In the above embodiment, the second guide rail 421 of the closing mechanism 400b is provided with a stop bar at the end away from the upright plate 510, which is used for the pushing mechanism 430 to push the two sets of semi-circular fixing components 110 to align before entering the traction zone 300. When the pushing mechanism 430 is working, the driving mechanism 432 starts and drives the reciprocating mechanism 431 to work. Subsequently, the rotating shaft 4315 rotates, causing the swing arm 4314 to make a circular motion around the axis of the rotating shaft 4315. The other end of the swing arm 4314 drives the first hinge block 4313 to make a circular motion around the circumference of the rotating shaft 4315. Then, through the first hinge block 4313, the horizontal bar 4311 is driven to rotate on the rotating shaft 4315. One side of 15 makes an elliptical circular motion. At the same time, when the elastic levers 4312 at both ends of the horizontal rod 4311 are in the lower half of the elliptical motion trajectory, they push the semi-circular fixed component 110 at the entrance and exit of the traction zone 300 to move towards the entrance of the traction zone 300. Multiple elastic levers 4312 are provided, which can cooperate with the boss 115 on the semi-circular fixed component 110 in turn to push the boss 115 to push the semi-circular fixed component 110 to move and contact the surface of the track mechanism 210. The track mechanism 210 enables the semi-circular fixed component 110 to repeatedly enter and exit the traction zone 300. Two sets of pushing mechanisms 430 are provided, which are respectively installed on the upper and lower parts of the mounting frame 500. The pushing mechanisms 430, which are symmetrically arranged, push the semi-circular fixed components 110 located on the upper part of the first track conveyor 200a and the lower part of the second track conveyor assembly to move. When the semi-circular fixed components 110 are pushed by the pushing mechanisms 430, the semi-circular fixed components 110 located at the entrance end of the traction zone 300 approach the stop bar, so that the edges of the two sets of semi-circular fixed components 110 are aligned. Then the closing mechanism 400b is activated to drive the two sets of second guide rails 421 to swing towards the traction zone 300 until the two sets of closing plates 422 are in contact, and the limiting protrusions 116 of the two sets of semi-circular fixed components 110 enter the corresponding limiting grooves 117 respectively.

[0038] Example 8 Please see Figures 1-9 The drive mechanism 432 includes: a drive motor 4321, mounted on the upper part of the mounting frame 500; a first pulley 4322, located on the output shaft of the drive motor 4321; four sets of second pulleys 4323, each set mounted on a rotating shaft 4315 of one of the two sets of reciprocating mechanisms 431; the second pulleys 4323 are arranged in pairs, one pair being driven to connect with the first pulley 4322 via a first synchronous belt 4324, and the other pair being driven to connect via a second synchronous belt; two sets of third pulleys 4325, each set mounted on a pair of second pulleys 4323; and a redirecting pulley 4326, located on the outer wall of the mounting frame 500; the redirecting pulley 4326 being driven to connect with the two sets of third pulleys 4325 via a third synchronous belt 4327.

[0039] In the above embodiment, the first pulley 4322 is mounted on the output shaft of the drive motor 4321. When the drive motor 4321 starts and drives the first pulley 4322 to rotate, it drives two second pulleys 4323 to rotate via the first synchronous belt 4324. When the two sets of second pulleys 4323 rotate, they drive the third pulley 4325 mounted on one side of them to rotate. The two sets of third pulleys 4325 are used to drive the other set of second pulleys 4323 to work. When the two sets of third pulleys 4325 rotate, they interact with the drive motor 4321. The third pulley 4325 of the third synchronous belt 4327 drives another third pulley 4325 to rotate. The middle section of the third synchronous belt 4327 passes through the redirecting pulley 4326, so that the third synchronous belt 4327 is in the shape of an "8". The redirecting pulley 4326 is used to change the rotation direction of the two ends of the third synchronous belt 4327, so that the rotation directions of the two sets of third synchronous belts 4327 are opposite, thereby causing the two symmetrically arranged pushing mechanisms 430 to push the semi-circular fixed component 110 to move in the same direction.

[0040] Example 9 Please see Figures 1-9The drive mechanism 432 further includes two sets of reciprocating drive components 433, which are used to drive the sector teeth 413 of the separating mechanism 400a and the closing mechanism 400b to reciprocate. Each reciprocating drive component 433 includes a fourth pulley 4331, located on the outer wall of the mounting bracket 500; wherein the fourth pulley 4331 and the third pulley 4325 are connected by a fourth synchronous belt 4332; and an eccentric rod 4. 333, one end of which is rotatable and eccentrically connected to the outer wall of the fourth pulley 4331; rack 4334, one end of which is rotatably connected to the other end of the eccentric rod 4333; reciprocating track 4335, which is installed on the outer wall of the mounting frame 500, and the rack 4334 is slidably disposed in the reciprocating track 4335; gear 4336, which is fixedly installed on the end of the rotating shaft 4315 away from the extension plate 411, and the gear 4336 meshes with the rack 4334.

[0041] In the above embodiment, when the third pulley 4325 is driven to rotate, the fourth synchronous belt 4332 drives the two sets of fourth pulleys 4331 to rotate, which in turn drives one end of the eccentric rod 4333 to make a circular motion around the axis of the fourth synchronous belt 4332. This causes the end of the eccentric rod 4333 near the rack 4334 to drive the rack 4334 to move back and forth in the reciprocating track 4335. The rack 4334 meshes with the gear 4336, causing the gear 4336 to intermittently rotate forward and backward during the reciprocating movement of the rack 4334. Then, the gear 4336 drives the rotating shaft 4315 to rotate forward and backward intermittently, causing the fan-shaped teeth 413 fixedly connected to the rotating shaft 4315 to oscillate intermittently, thereby achieving the purpose of driving the separation mechanism 400a and the closing mechanism 400b to work.

[0042] Example 10 Please see Figures 1-9 The semi-cylindrical housing 111 is provided with an inflation hole 118, one end of which is connected to the outer wall; a quick-connect valve 119 is provided at one end of the inflation hole 118 near the outer wall of the semi-cylindrical housing 111; wherein, the inflation hole 118 is connected to each of the elastic airbags 120, and each of the elastic airbags 120 is provided with a solenoid valve between the inflation hole 118 and the inflation hole.

[0043] In the above embodiments, when it is necessary to inflate or deflate each elastic airbag 120, the air pump is connected to the quick-connect valve 119 through a pipeline. The pipeline is set on the electric telescopic rod 4162. The electric telescopic rod 4162 drives the pipeline to contact the quick-connect valve 119. After the quick-connect valve 119 is opened, the inflation port 118 is connected to the pipeline, the solenoid valve is opened, and the air pump is used to pump air out of each elastic airbag 120. The electric telescopic rod 4162 drives the pipeline to approach or disengage from the quick-connect valve 119, which is a conventional technical means, so it will not be described in detail here.
