Description

Technical Field

[0001] This invention relates to the field of cable processing, specifically to a wheel-type aluminum sheath bonding device and method. Background Technology

[0002] With the development of the national economy and energy construction, the demand for electricity is increasing, the voltage transmission level is getting higher and higher, and new cable structures are constantly emerging. Smooth aluminum sheathed cables are one of them. When processing smooth aluminum sheathed cables, the aluminum sheath needs to be fitted on the outside of the cable core. The aluminum sheath needs to fit tightly. If the aluminum sheath is used with an interference fit, it will be difficult to insert and it will also easily cause damage to the cable core. Therefore, the aluminum sheath usually adopts a clearance fit. After being fitted on the outside of the cable core, the diameter of the aluminum sheath is reduced by a diameter reduction device to achieve a tight fit between the aluminum sheath and the cable core.

[0003] For example, our company's earlier patent application, authorized by publication number CN111524657B, discloses a production equipment and method for extruded composite smooth aluminum sheathed cables. The production equipment includes an aluminum sheath extrusion device, a wheel-type diameter reduction device, a preheating device, a multi-layer co-extrusion device, and a cooling water tank. The aluminum sheath extrusion device continuously extrudes aluminum sheaths. After being covered with aluminum sheaths, the cable passes through a shaft hole and is compressed to the outer diameter size designed by the wheel-type diameter reduction device, so that the aluminum sheath is completely wrapped around the surface of the cable core. The preheating device heats the aluminum sheath, and the multi-layer co-extrusion device combines the aluminum sheath with hot melt adhesive, PE sheath, PVC sheath, and conductive layer, and then cools and shapes it through the cooling water tank.

[0004] In the aforementioned patent, a wheel-type diameter reduction technology is used, with three rolling rollers distributed at 120° intervals. The extruded aluminum sleeve passes through this rolling roller device. The diameter reduction progress of the three rolling rollers is adjusted according to the outer diameter of the aluminum sleeve, so that the extruded aluminum sleeve is compressed to the outer diameter size designed by the process, and the extruded aluminum sleeve is firmly wrapped around the surface of the cable core.

[0005] However, the drawback of the aforementioned patent is that the fixed structure of the rolling roller makes it impossible to adjust, resulting in poor applicability. Our company subsequently applied for a patent with authorization announcement number CN114758850B, which discloses a smooth wheel type aluminum sheath bonding device, including a base. A mounting platform is vertically arranged on the base, and a base is arranged on one side of the mounting platform in the thickness direction. Through holes are opened on the base and the mounting platform, and the through holes penetrate the mounting platform and the base. Multiple sets of diameter reduction components are arranged on the side of the base away from the mounting platform. The diameter reduction components are evenly arranged around the through holes. Each diameter reduction component includes a mounting seat and a diameter reduction part. The mounting seat is slidably arranged on the base, and the mounting seat slides towards or away from the center of the through hole. The diameter reduction part is arranged at the end of the mounting seat facing the through hole.

[0006] The aforementioned patent's gear ring, in conjunction with the drive gear, can drive the base to rotate the rolling rollers around the through hole, thereby achieving the reduction of the aluminum sheath diameter. Simultaneously, the pressure block allows for adjustment of the reduction range, making the reduction assembly suitable for cables of different sizes. However, the patent's drawback is that while it can adapt to the reduction of cables of different sizes within a certain range by adjusting the spacing of the four sets of rolling rollers, the rolling rollers themselves are non-deformable structures, limiting their applicability to cables of a limited size. If the diameter of the subsequently reduced cable differs significantly from the original reduced cable diameter, it is still necessary to replace the equipment.

[0007] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Summary of the Invention

[0008] The purpose of this invention is to provide a wheel-type aluminum sheath bonding device and method to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The wheel-type aluminum sheath bonding device includes: a reduced diameter base, which is used to install a reduced diameter wheel assembly;

[0011] The reducing wheel assembly has multiple sets; in this embodiment, the reducing wheel assembly has three sets.

[0012] The wheel set gear adjustment mechanism is used to select a suitable diameter reduction wheel set and drive the rollers of the diameter reduction wheel set to approach the aluminum-sheathed cable to be reduced in diameter.

[0013] Cable pulling equipment used for pulling aluminum-sheathed cables.

[0014] The reduced-diameter wheel assembly includes a reduced-diameter housing, an infeed roller turntable, and a guide rod. A cable passage hole is provided in the center of the reduced-diameter housing along the left-right direction for the passage of the reduced-diameter cable. An annular turntable mounting groove is provided on the right side of the reduced-diameter housing, and an annular infeed roller turntable is rotatably mounted inside the groove. An extension arm extends upward from the top of the infeed roller turntable. A clearance groove is provided at the top of the turntable mounting groove for the extension arm to extend and move. Four sets of pushing grooves are arranged in a circular array on the infeed roller turntable. The pushing grooves are generally arc-shaped, and... The arc-shaped pushing groove is inclined to the radius of the feed roller turntable, that is, the inner end of the arc-shaped pushing groove is closer to the center of the feed roller turntable than the outer end; an end cover is fastened to the right side of the reduced diameter shell, the end cover is generally disc-shaped, and four guide grooves arranged in a circular array are opened on the left side of the end cover, and the guide grooves are arranged along the radial direction of the end cover; a total of four guide rods are provided, the guide rods are slidably disposed in the guide grooves, the outer end of the guide rods is rotatably connected to a sliding block, the sliding block is slidably disposed in the pushing groove, and the inner end of the guide rods is rotatably mounted with a rolling wheel.

[0015] Furthermore, the sliding block is rotatably connected to the outer end of the guide rod by a slider connecting screw.

The slider connecting screw passes through the rotatable connecting hole and is threadedly fixed to the threaded hole on the sliding block, and the slider connecting screw is rotatably connected to the rotatable connecting hole.

[0016] Furthermore, the rolling roller is rotatably connected to the rolling roller shaft via bearings, and both ends of the rolling roller shaft are fixedly mounted on the rolling roller seat by fixing screws. The rolling roller seat is fixedly mounted on the inner end of the guide rod. The axial lengths of the rolling rollers in the three sets of diameter reduction rollers are different, and the length of the rolling rollers in the diameter reduction roller sets gradually increases from left to right, in order to adapt to the diameter reduction requirements of cables of different diameters.

[0017] Furthermore, the reduced-diameter base includes a base plate, on the top left and right sides of the base plate respectively, with a left side plate and a right side plate fixedly installed. The center of the left side plate and the right side plate has a through hole for the cable to pass through. Four first guide shafts are fixed between the left side plate and the right side plate. The reduced-diameter housing is slidably connected to the first guide shafts through a first linear bearing fixed at the end of the bracket connecting arm. The wheel set gear adjustment mechanism includes a wheel set position adjustment mechanism and a roller advance mechanism.

[0018] Furthermore, the wheel set position adjustment mechanism includes a position adjustment trapezoidal screw, a wheel set connecting seat, and a position adjustment motor. The wheel set connecting seat is fixedly installed at the bottom of the reduced-diameter housings of several reduced-diameter wheel sets for connecting the several reduced-diameter housings. The position adjustment trapezoidal screw includes a trapezoidal screw rod and a screw rod nut.

The screw rod nut is driven and connected to the trapezoidal screw rod, and the screw rod nut is fixedly installed at the bottom of the wheel set connecting seat through a nut seat. When the trapezoidal screw rod rotates, it can drive several reduced-diameter wheel sets to move left and right along the first guide shaft through the nut seat. The position adjustment motor drives and connects to the position adjustment trapezoidal screw rod. The position adjustment motor is fixedly installed on the right side of the right side plate, and the output shaft of the position adjustment motor passes through the right side plate and is driven and connected to the trapezoidal screw rod through a coupling.

[0019] Furthermore, the rolling mill feed mechanism includes a set of hydraulic cylinders and a hydraulic cylinder bracket for mounting the hydraulic cylinders. The hydraulic cylinder bracket is fixedly mounted on the top of the base plate of the reduced-diameter base, and the hydraulic cylinders are fixedly mounted on the top of the hydraulic cylinder bracket. The hydraulic cylinders are arranged along the front-rear direction. At the same time, a push fork is fixedly mounted on the output shaft of the hydraulic cylinder. The push fork is Y-shaped, and a push shaft is fixedly connected to the front end of the push fork. The end of the extension arm has a push notch corresponding to the push shaft. The push notch is set to open towards the side of the push fork.

[0020] Furthermore, the cable traction device includes a lower traction conveyor line and an upper traction conveyor line. The lower traction conveyor line is located directly below the upper traction conveyor line. The cable passes between the lower and upper traction conveyor lines, which work together to pull the cable from left to right. The cable traction device also includes a traction base for mounting the lower and upper traction conveyor lines. The lower traction conveyor line is mounted on a first horizontal position adjustment mechanism, which is mounted on a first vertical position adjustment mechanism. The first vertical position adjustment mechanism is fixedly mounted on the bottom of the traction base. The first horizontal position adjustment mechanism is used to adjust the position of the lower traction conveyor line in the front-to-back direction, and the first vertical position adjustment mechanism is used to adjust the position of the lower traction conveyor line in the vertical direction.

[0021] The upper traction conveyor line is mounted on the second horizontal position adjustment mechanism, which is mounted on the second vertical position adjustment mechanism. The second vertical position adjustment mechanism is fixedly mounted on the upper part of the traction machine base. The second horizontal position adjustment mechanism is used to adjust the position of the upper traction conveyor line in the front-back direction, and the second vertical position adjustment mechanism is used to adjust the position of the lower traction conveyor line in the up-down direction.

[0022] Furthermore, the lower traction conveyor line includes a lower traction bracket and a lower traction motor. The left and right ends of the lower traction bracket are rotatably connected to a first driven roller and a first driving roller via bearings and bearing seats, respectively. Several first auxiliary rollers are rotatably arranged on the top of the lower traction bracket. A first conveyor belt is driven between the first driving roller and the first driven roller. At least three sets of first arc-shaped grooves are sequentially opened on the sides of the first auxiliary roller, the first driving roller, and the first driven roller in the axial direction, and the width and depth of the three sets of first arc-shaped grooves increase sequentially. The first conveyor belt is made of flexible material.

[0023] Furthermore, the upper traction conveyor line includes an upper traction bracket and an upper traction motor. The left and right ends of the upper traction bracket are rotatably connected to a second driven roller and a second driving roller via bearings and bearing seats, respectively. Several second auxiliary rollers are rotatably arranged at the bottom of the upper traction bracket, and these auxiliary rollers are located between the second driving roller and the second driven roller. A second conveyor belt is drively connected between the second driving roller and the second driven roller. Similarly, at least three sets of second arc-shaped grooves are sequentially opened on the sides of the second auxiliary roller, the second driving roller, and the second driven roller in the axial direction, and the width and depth of the three sets of second arc-shaped grooves increase sequentially. The second conveyor belt is also made of flexible material.

[0024] The method for reducing the diameter of the aluminum sheath in aluminum-sheathed cables includes the following steps:

[0025] First, select a suitable reduction wheel set based on the diameter of the cable being processed. Then, the position adjustment motor of the wheel set adjustment mechanism activates, driving several reduction wheel sets to move synchronously left and right via the position adjustment trapezoidal screw. When a suitable reduction wheel set aligns with the push fork, the position adjustment motor stops. The output shaft of the hydraulic cylinder extends, pushing the push fork forward. The push shaft enters the push notch, driving the feed roller turntable to rotate. The distance between the four sets of rolling rollers within the same reduction wheel set can be controlled within a certain range by controlling the extension and retraction of the hydraulic cylinder.

[0026] The horizontal positions of the lower traction conveyor line and the upper traction conveyor line are adjusted by the first horizontal position adjustment mechanism and the second horizontal position adjustment mechanism respectively, so that the first arc-shaped groove and the second arc-shaped groove of appropriate size are aligned with the cable to be conveyed.

[0027] The lower traction conveyor line and the upper traction conveyor line are adjusted to be close to each other by the first vertical position adjustment mechanism and the second vertical position adjustment mechanism, so that the first conveyor belt and the second conveyor belt exert a certain pressure on the cable, thereby enabling the cable traction equipment to traction and convey the cable.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This device achieves rapid adaptation to cables of different diameters by using multiple sets of reducing rollers with different axial lengths and employing multiple sets of arc-shaped grooves of different specifications to accommodate these roller sets. This eliminates the cumbersome steps of changing production lines or disassembling the rollers, thus expanding the device's applicability.

[0030] Meanwhile, the traction equipment uses a flexible conveyor belt with arc-shaped grooves, which increases the contact area with the cable, avoids surface damage that may be caused by traditional rigid conveying, and effectively protects the cable surface. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0051] The original patent, due to the non-deformable structure of the rolling mill, could only accommodate cable diameter reduction operations within a certain limited range, such as... Figure 19 As shown, if the diameter of the subsequently reduced-diameter cable differs too much from the diameter of the original reduced-diameter cable, the original rolling roller is no longer applicable.

[0052] The conventional method is to replace the production line or disassemble the original rolling mill and replace it with a new rolling mill.

[0053] Please see Figure 1-4 A wheel-type aluminum sheath bonding device, comprising:

[0054] The reduced diameter base 100 is used to mount the reduced diameter wheel assembly 200.

[0055] The reduced diameter wheel set 200 is provided in multiple sets. In this embodiment, the reduced diameter wheel set 200 is provided in three sets.

[0056] Wheel set gear adjustment mechanism 300 is used to select a suitable reduced diameter wheel set 200 and drive the roller 400 of the reduced diameter wheel set 200 to approach the aluminum sheathed cable to be reduced in diameter.

[0057] Cable pulling equipment 500, used for pulling aluminum-sheathed cables;

[0058] like Figure 5-7 As shown, in this scheme, the reduced diameter wheel assembly 200 includes a reduced diameter housing 210, an infeed roller turntable 220, and a guide rod 240; the reduced diameter housing 210 has a cable passage hole 211 in the middle along the left and right direction, which is used for the passage of the reduced diameter cable;

[0059] The right side of the reduced diameter housing 210 is provided with an annular turntable mounting groove 212, and an annular feed roller turntable 220 is rotatably arranged inside the turntable mounting groove 212.

[0060] An extension arm 221 extends upward from the top of the feed roller turntable 220; a clearance groove 213 is provided at the top of the turntable mounting groove 212 to allow the extension arm 221 to extend and move.

[0061] The feed roller turntable 220 has four sets of pushing grooves 222 arranged in a circular array. The pushing grooves 222 are generally arc-shaped, and the arc-shaped pushing grooves 222 are inclined to the radius of the feed roller turntable 220. That is, the inner end of the arc-shaped pushing grooves 222 is closer to the center of the feed roller turntable 220 than the outer end.

[0062] An end cap 230 is fastened to the right side of the reduced-diameter housing 210. The end cap 230 is generally disc-shaped. Four guide grooves 231 arranged in a circular array are opened on the left side of the end cap 230, and the guide grooves 231 are arranged along the radial direction of the end cap 230.

[0063] Four guide rods 240 are provided in total. The guide rods 240 are slidably disposed in the guide grooves 231. The outer ends of the guide rods 240 are rotatably connected to sliding blocks 241, which are slidably disposed in the push grooves 222.

[0064] When the feed roller turntable 220 rotates, the sliding block 241 in the push groove 222 moves from the outer end to the inner end of the push groove 222. Since the inner end of the push groove 222 is closer to the center of the feed roller turntable 220 than the outer end, the sliding block 241 also moves towards the center of the feed roller turntable 220. Since the guide rod 240 is slidably disposed in the guide groove 231, and the sliding block 241 is rotatably disposed at the outer end of the guide rod 240, the inner end of the guide rod 240 also moves inward along the guide groove 231.

[0065] Specifically, the sliding block 241 is rotatably connected to the outer end of the guide rod 240 by a slider connecting screw 243. The outer end of the guide rod 240 is provided with a rotating connecting hole 242, and the sliding block 241 is provided with a threaded hole. The slider connecting screw 243 passes through the rotating connecting hole 242 and is threadedly fixed to the threaded hole on the sliding block 241. The slider connecting screw 243 is rotatably connected to the rotating connecting hole 242.

[0066] A roller 400 is rotatably mounted on the inner end of the guide rod 240; such as Figure 7 As shown, specifically, the rolling wheel 400 is rotatably connected to the rolling wheel shaft 402 via bearings, and both ends of the rolling wheel shaft 402 are fixedly mounted on the rolling wheel seat 401 by fixing screws 403. The rolling wheel seat 401 is fixedly mounted on the inner end of the guide rod 240.

[0067] like Figure 8 As shown, it is worth noting that the axial lengths of the rolling rollers 400 in the three sets of diameter reduction roller groups 200 are different, and the length of the rolling rollers 400 in the diameter reduction roller groups 200 gradually increases from left to right, in order to adapt to the diameter reduction requirements of cables of different diameters.

[0068] Meanwhile, in this scheme, the diameter of the rolling mill 400 gradually increases from the middle to both ends, making the sidewall of the rolling mill 400 generally arc-shaped.

[0069] The reduced-diameter housing 210 has bracket connecting arms 250 extending outward from its four corners; a first linear bearing 251 is fixedly installed at the end of the bracket connecting arm 250.

[0070] like Figure 9-11 As shown, the reduced-diameter base 100 includes a base plate 101. A left side plate 102 and a right side plate 103 are fixedly installed on the top left and right sides of the base plate 101, respectively. The center of the left side plate 102 and the right side plate 103 is provided with a through hole for the cable to pass through.

[0071] Four first guide shafts 104 are fixed between the left side plate 102 and the right side plate 103. The reduced diameter housing 210 is slidably connected to the first guide shafts 104 through the first linear bearing 251 fixed at the end of the bracket connecting arm 250.

[0072] The wheelset gear adjustment mechanism 300 includes a wheelset position adjustment mechanism 310 and a wheel feed mechanism 320; the wheelset position adjustment mechanism 310 includes a position adjustment trapezoidal lead screw 311, a wheelset connecting seat 312, and a position adjustment motor 313.

[0073] The wheel assembly connecting seat 312 is fixedly installed at the bottom of the reduced diameter housing 210 of several reduced diameter wheel assemblies 200 for connecting several reduced diameter housings 210.

[0074] The position adjustment trapezoidal lead screw 311 includes a trapezoidal lead screw 3111 and a lead screw nut 3112. The trapezoidal lead screw 3111 is vertically fixed at the top center of the reduced-diameter base 100 via bearings and bearing seats, and is arranged along the left-right direction. The lead screw nut 3112 is drivenly connected to the trapezoidal lead screw 3111, and the lead screw nut 3112 is fixedly installed at the bottom of the wheel assembly connecting seat 312 via a nut seat 3113. When the trapezoidal lead screw 3111 rotates, it can drive several reduced-diameter wheel assemblies 200 to move left and right along the first guide shaft 104 through the nut seat 3113.

[0075] The trapezoidal lead screw has a self-locking characteristic, which can meet the requirement of adjusting the position of the reduced diameter wheel assembly 200 in this solution; and prevent the reduced diameter wheel assembly 200 from moving as a whole when the cable is being routed.

[0076] The position adjustment motor 313 drives the position adjustment trapezoidal lead screw 311; the position adjustment motor 313 is fixedly installed on the right side of the right side plate 103, and the output shaft of the position adjustment motor 313 passes through the right side plate 103 and is connected to the trapezoidal lead screw 3111 through a coupling.

[0077] When the position adjustment motor 313 of the wheel set position adjustment mechanism 310 is activated, it drives several reduced diameter wheel sets 200 to move synchronously left and right through the position adjustment trapezoidal screw 311.

[0078] The rolling mill feed mechanism 320 includes a set of hydraulic cylinders 321 and a hydraulic cylinder bracket 322 for mounting the hydraulic cylinders 321.

[0079] The hydraulic cylinder bracket 322 is fixedly installed on the top of the base plate 101 of the reduced diameter base 100, and the hydraulic cylinder 321 is fixedly installed on the top of the hydraulic cylinder bracket 322. The hydraulic cylinder 321 is arranged along the front and rear direction. At the same time, a push fork 323 is fixedly installed on the output shaft of the hydraulic cylinder 321. The push fork 323 is Y-shaped, and a push shaft 324 is fixedly connected to the front end of the push fork 323.

[0080] Correspondingly, the end of the extension arm 221 is provided with a push notch 325 corresponding to the push shaft 324; the push notch 325 is provided with an opening on the side facing the push fork 323.

[0081] When using this invention, taking the leftmost reducing roller group 200 as an example, when the output shaft of the hydraulic cylinder 321 extends, it pushes the shift fork 323 forward. At this time, the push shaft 324 enters the push notch 325, pushing the feed roller turntable 220 to rotate. By controlling the extension and retraction of the hydraulic cylinder 321, the distance between the four sets of rolling rollers 400 in the same reducing roller group 200 can be controlled within a certain range, thereby satisfying the reducing operation of cables of a certain size within a certain range.

[0082] The three sets of reducing roller sets 200 have different axial lengths of their rollers 400, with the axial length of the rollers 400 gradually increasing from left to right, in order to accommodate the reduction requirements of cables with different diameters.

[0083] When it is necessary to reduce the diameter of a longer cable, the position adjustment motor 313 of the wheel set position adjustment mechanism 310 is activated, and the position adjustment trapezoidal screw 311 drives several reduction wheel sets 200 to move to the left as a whole, so that the push notch 325 on the extension arm 221 of the middle reduction wheel set 200 is aligned with the push shaft 324 at the front end of the push fork 323; at this time, another set of reduction wheel sets 200 can be driven to use a longer axial length roller 400 to reduce the diameter of the cable.

[0084] This solution achieves the diameter reduction requirements of cables with different diameters over a wider range by installing multiple sets of diameter reduction rollers 200 with rollers 400 of different axial lengths.

[0085] At the same time, the wheel set position adjustment mechanism 310 is used to adjust the position of the diameter reduction wheel set that needs to be reduced in diameter, so that the diameter reduction position of the cable is always in the same position on the production line.

[0086] like Figure 12 As shown, in this scheme, the cable pulling device 500 includes a lower pulling conveyor line 510 and an upper pulling conveyor line 550. The lower pulling conveyor line 510 is located directly below the upper pulling conveyor line 550. The cable passes between the lower pulling conveyor line 510 and the upper pulling conveyor line 550. The lower pulling conveyor line 510 and the upper pulling conveyor line 550 work together to pull the cable from left to right.

[0087] Specifically, the cable traction device 500 also includes a traction base 540, which is used to install the lower traction conveyor line 510 and the upper traction conveyor line 550.

[0088] The lower traction conveyor line 510 is installed on the first horizontal position adjustment mechanism 520, which is installed on the first vertical position adjustment mechanism 530, which is fixedly installed on the bottom of the traction machine base 540.

[0089] The first horizontal position adjustment mechanism 520 is used to adjust the position of the lower traction conveyor line 510 in the front-back direction, and the first vertical position adjustment mechanism 530 is used to adjust the position of the lower traction conveyor line 510 in the vertical direction.

[0090] The upper traction conveyor line 550 is installed on the second horizontal position adjustment mechanism 560, which is installed on the second vertical position adjustment mechanism 570, which is fixedly installed on the upper part of the traction machine base 540.

[0091] The second horizontal position adjustment mechanism 560 is used to adjust the position of the upper traction conveyor line 550 in the front-to-back direction, and the second vertical position adjustment mechanism 570 is used to adjust the position of the lower traction conveyor line 510 in the vertical direction.

[0092] like Figure 13-14 As shown, in this scheme, the lower traction conveyor line 510 includes a lower traction bracket 511 and a lower traction motor 517. The left and right ends of the lower traction bracket 511 are rotatably connected to a first driven roller 513 and a first driving roller 512 through bearings and bearing seats, respectively. A plurality of first auxiliary rollers 514 are rotatably arranged on the top of the lower traction bracket 511. The plurality of first auxiliary rollers 514 are located between the first driving roller 512 and the first driven roller 513. A first conveyor belt 516 is drivenly connected between the first driving roller 512 and the first driven roller 513.

[0100] like Figure 15-17 As shown, the upper traction conveyor line 550 has the same structure as the lower traction conveyor line 510, and is arranged in a mirror image. The upper traction conveyor line 550 includes an upper traction bracket 551 and an upper traction motor 517. The left and right ends of the upper traction bracket 551 are rotatably connected to a second driven roller 553 and a second driving roller 552 through bearings and bearing seats, respectively. A plurality of second auxiliary rollers 554 are rotatably arranged at the bottom of the upper traction bracket 551, and the plurality of second auxiliary rollers 554 are located between the second driving roller 552 and the second driven roller 553.

The upper traction motor 517 is fixedly installed at the front end of the upper traction bracket 551, and the output shaft of the upper traction motor 517 is drivenly connected to the second driving roller 552.

[0101] Specifically, the second auxiliary roller 554 is rotatably connected to the rotating shaft via a bearing, and the two ends of the rotating shaft are provided with external threads. The two ends of the rotating shaft pass through the front and rear ends of the upper traction bracket 551 and are fixed by nuts.

[0102] The second vertical position adjustment mechanism 570 includes a second lower mounting base 571 and a second upper mounting base 572.

The upper and lower ends of the lead screw 576 are rotatably connected to the second upper mounting base 572 and the second lower mounting base 571 respectively through bearings. At the same time, the lead screw nut of the fourth trapezoidal lead screw 576 is fixedly installed on the fourth vertical position adjustment seat 575. The top of the lead screw 576 passes through the second upper mounting base 572 and is fixedly installed with a handwheel.

[0104] By turning the screw of the fourth trapezoidal screw 576 with the handwheel, the fourth vertical position adjustment seat 575 can be moved up and down along the fourth guide shaft 573.

[0105] The second horizontal position adjustment mechanism 560 includes a second front mounting base 561, which is located at the front end of the fourth vertical position adjustment base 575. Two fifth guide shafts 562 are fixedly installed between the second front mounting base 561 and the fourth vertical position adjustment base 575. The second horizontal position adjustment base 564 is slidably connected to the fifth guide shafts 562 through a fifth linear bearing 563. A fifth trapezoidal screw 565 is also installed between the second front mounting base 561 and the fourth vertical position adjustment base 575. The front and rear ends of the screw of the fifth trapezoidal screw 565 are rotatably connected to the second front mounting base 561 and the fourth vertical position adjustment base 575 through bearings, respectively. At the same time, the screw nut of the fifth trapezoidal screw 565 is fixedly installed on the second horizontal position adjustment base 564. The front end of the screw of the fifth trapezoidal screw 565 passes through the second front mounting base 561 and is fixedly installed with a handwheel.

[0106] By turning the screw of the fifth trapezoidal screw 565 with the handwheel, the second horizontal position adjustment seat 564 can be moved back and forth along the fifth guide shaft 562;

[0107] Meanwhile, in this scheme, the lower end of the second horizontal position adjustment seat 564 is fixedly connected to the top of the upper traction bracket 551.

[0108] The sides of the first auxiliary roller 514, the first active roller 512 and the first driven roller 513 are sequentially provided with at least three sets of first arc-shaped grooves 515 in the axial direction, and the width and depth of the three sets of first arc-shaped grooves 515 increase sequentially.

[0109] The first conveyor belt 516 is made of flexible material. In this solution, the first conveyor belt 516 is made of PU material. When the cable passes between the first conveyor belt 516 above the first arc groove 515 and the second conveyor belt 556 below the second arc groove 555, the cable will compress the first conveyor belt 516 to deform.

[0110] Similarly, at least three sets of second arc-shaped grooves 555 are sequentially formed on the sides of the second auxiliary roller 554, the second active roller 552 and the second driven roller 553 in the axial direction, and the width and depth of the three sets of second arc-shaped grooves 555 increase sequentially.

[0111] The second conveyor belt 556 is also made of flexible material. In this solution, the second conveyor belt 556 is made of PU material. When the cable passes between the second conveyor belt 556 above the second arc groove 555 and the second conveyor belt 556 below the second arc groove 555, the cable will compress the second conveyor belt 556 to deform.

[0112] like Figure 18 As shown, the first conveyor belt 516 and the second conveyor belt 556 approach each other and press against the cable. At this time, the cable will squeeze the first conveyor belt 516 and the second conveyor belt 556 to deform at the arc-shaped groove. The arc-shaped groove will limit this deformation, so that the deformation is not too large. This allows the first conveyor belt 516 and the second conveyor belt 556 to deform at the corresponding arc-shaped groove, so that the conveyor belt can have more contact area with the cable at the deformation point. This allows the first conveyor belt 516 and the second conveyor belt 556 to "wrap" the cable, and the pressure on the cable will be distributed to more parts of the cable. Thus, while ensuring the conveying effect, the conveyor belt itself will not "tear" and damage the surface of the cable (because the final cable surface will be extruded with one or more layers of polymer material, such as PU or PVC material, etc., and if the contact area between the conveyor belt and these polymer materials is too small, the conveyor belt can easily tear the surface of these materials, causing scratches or even deformation of the final cable).

[0113] In this solution, the combination of multiple sets of first arc-shaped grooves 515 and multiple sets of second arc-shaped grooves 555 serves the same purpose as the multiple sets of tapered wheel sets 200, which is to adapt to cables of different diameters. However, in this case, in order to meet the conveying requirements of cables of different diameters, thicker cables are conveyed by the conveyor belts at the deeper and wider parts of the first arc-shaped grooves 515 and second arc-shaped grooves 555.

[0114] Furthermore, because the conveyor belt, being made of flexible material, can deform at the curved groove, the diameter of the cable to be conveyed varies within a small range.

[0115] When using this invention, the following steps are included:

[0116] First, select a suitable reduction diameter wheel set 200 according to the wire diameter of the cable being processed. At this time, the position adjustment motor 313 of the wheel set position adjustment mechanism 310 is activated, which drives several reduction diameter wheel sets 200 to move synchronously left and right through the position adjustment trapezoidal screw 311. When the suitable reduction diameter wheel set 200 is aligned with the push fork 323, the position adjustment motor 313 stops. The output shaft of the hydraulic cylinder 321 extends, pushing the fork 323 forward, and the push shaft 324 enters the push notch 325, pushing the feed roller turntable 220 to rotate. The distance between the four sets of rolling rollers 400 in the same set of reduction diameter wheel sets 200 can be controlled within a certain range by controlling the extension and retraction of the hydraulic cylinder 321.

[0117] The horizontal positions of the lower traction conveyor line 510 and the upper traction conveyor line 550 are adjusted by the first horizontal position adjustment mechanism 520 and the second horizontal position adjustment mechanism 560 respectively, so that the first arc-shaped groove 515 and the second arc-shaped groove 555 of appropriate size are aligned with the cable to be conveyed.

[0118] However, by adjusting the lower traction conveyor line 510 and the upper traction conveyor line 550 to be close to each other through the first vertical position adjustment mechanism 530 and the second vertical position adjustment mechanism 570, the first conveyor belt 516 and the second conveyor belt 556 exert a certain pressure on the cable, thereby enabling the cable traction device 500 to traction and convey the cable.

[0119] In the description of this invention, it should be noted that the positions of the cable traction device 500 and the reduced-diameter wheel set 200 are merely illustrative and do not represent the actual distance between them as shown in the diagram. Furthermore, the terms "upper," "lower," "inner," "outer," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, terms such as "setup" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
