Description

Technical Field

[0001] This invention relates to a stranding machine, and more particularly to a cantilevered moving wire-laying type single stranding machine. Background Technology

[0002] Existing single-strand cable winding machines generally include a stranding mechanism, a winding mechanism, a take-up reel, and a take-up drive mechanism. The winding and stranding mechanisms are located on the same side of the take-up reel and are coaxially arranged. The stranding spindle of the stranding mechanism rests against one side of the take-up reel, while the take-up drive mechanism is located on the other side of the take-up reel and connected to it. During winding, the cable passes through the stranding mechanism and then the winding mechanism, finally being wound onto the take-up reel. However, in existing single-strand cable winding machines, the stranding spindle of the stranding mechanism needs to be relatively long because sufficient space needs to be left for the cantilever of the winding mechanism. Currently, however, there is no support for the end of the stranding spindle closest to the take-up reel; this end is suspended, which easily causes significant vibration during operation. The take-up reel and various shaft components experience uneven stress, resulting in poor support rigidity of the shaft components, unstable and unreliable operation, and wear and tear after long-term operation, shortening its service life. Summary of the Invention

[0003] The purpose of this invention is to provide a cantilevered moving wire winding machine with uniform force distribution on the spool and each shaft, good support rigidity, stable and reliable operation, and long service life.

[0004] To achieve the above objectives, the cantilevered mobile single-strand winding machine provided by the present invention includes a stranding mechanism, a winding mechanism, a take-up reel, and a take-up drive mechanism; the stranding mechanism includes a stranding spindle, the take-up drive mechanism includes a take-up drive shaft, the take-up reel is located between the stranding mechanism and the take-up drive shaft, and the stranding spindle abuts against the center of one side of the take-up reel via a top cone; one end of the take-up drive shaft abuts against the center of the other side of the take-up reel, and the take-up drive mechanism drives the take-up reel to rotate via the take-up drive shaft; the winding mechanism includes a winding drive device, a cantilever drive shaft, a winding wheel, a fixed shaft, a base, and a first translation drive. The device comprises: one end of the fixed shaft fixed to the base; a take-up drive shaft coaxially and rotatably sleeved within the fixed shaft; a cantilever drive shaft coaxially sleeved outside the fixed shaft; a bearing assembly provided between the cantilever drive shaft and the fixed shaft to support the fixed shaft; the cantilever drive shaft being rotatable and axially sliding relative to the fixed shaft; a cable guide wheel disposed on the cantilever drive shaft and located outside the take-up reel to guide the cable output from the stranding mechanism to be wound onto the take-up reel; a first translation drive device driving the cantilever drive shaft to slide along its own axial direction; and a cable guide drive device driving the cantilever drive shaft to rotate. Compared with the prior art, the present invention arranges the stranding mechanism on one side of the take-up reel, the take-up drive mechanism on the other side, and the cable laying mechanism on the same side as the take-up drive mechanism, thus allowing the cable laying mechanism and the stranding mechanism to be arranged opposite each other. Furthermore, by providing a fixed shaft and a base, the take-up drive shaft is fitted inside the fixed shaft, and the take-up drive shaft abuts against the take-up reel, thereby working with the stranding spindle to clamp the take-up reel. Simultaneously, by fitting a cantilever drive shaft outside the fixed shaft and placing a bearing assembly between them, the bearing assembly can support both the fixed shaft and the take-up drive shaft, while also allowing the cantilever drive shaft to rotate and slide axially relative to the fixed shaft. Therefore, this arrangement provides stable support to the end of the take-up drive shaft near the take-up reel, preventing excessive vibration during rotation of the take-up drive shaft and the take-up reel. This results in more even stress distribution on each shaft and the take-up reel, good support rigidity, and thus very stable and reliable operation, avoiding wear and tear during long-term operation and effectively extending service life.

[0005] Preferably, the bearing assembly includes a bearing housing, a rotating bearing, and rollers. The bearing housing is spaced between the cantilever drive shaft and the fixed shaft, and the rotating bearing is disposed between the bearing housing and the cantilever drive shaft. The rollers are pivotally connected to the bearing housing via a spindle and are located below the fixed shaft to support the fixed shaft and roll in contact with it. By providing the rotating bearing outside the bearing housing, the fixed shaft and the cantilever drive shaft are rotatably arranged relative to each other. Furthermore, by providing the rollers inside the bearing housing, the cantilever drive shaft can support the fixed shaft and the take-up drive shaft, thereby providing an additional support point at the front end of the take-up drive shaft. This prevents vibration caused by one end of the take-up drive shaft and the fixed shaft being suspended, improving support rigidity and thus enhancing operational stability.

[0006] Specifically, the roller's surface has a circular arc-shaped groove structure in its cross-section to contact and engage with the outer side of the fixed shaft. By utilizing the circular arc-shaped groove to engage with the outer side of the fixed shaft, the roller and the fixed shaft surface make surface contact, increasing the contact area between the fixed shaft and the roller, thereby making the support more stable and ensuring the stability of the equipment operation.

[0007] Specifically, the rotation axis of the roller is perpendicular to the central axis of the fixed shaft. This allows the roller to roll as the cantilever drive shaft moves axially, achieving rolling contact between the cantilever drive shaft and the fixed shaft, effectively reducing frictional resistance.

[0008] Preferably, the cable winding mechanism further includes a movable base, which is movably mounted on the frame. The cantilever drive shaft is rotatably mounted on the movable base. The first translation drive device is mounted on the frame and drives the movable base to move along the central axis of the cantilever drive shaft. By providing the movable base, the cantilever drive shaft can be slidably fitted outside the fixed shaft, thereby driving the cable winding wheel to guide the cable onto the take-up reel.

[0009] Specifically, the cable laying drive device includes a first servo motor, a first pulley set, a ground shaft, and a second pulley set. The first servo motor is mounted on the movable base and its output end is connected to the cantilever drive shaft. The output end of the first servo motor is connected to one end of the ground shaft through the first pulley set and drives the ground shaft to rotate. The ground shaft is mounted on the frame and its other end is connected to the stranding spindle through the second pulley set and drives the stranding spindle to rotate. By using the first pulley set, the ground shaft, and the second pulley set to drive the stranding spindle, the cantilever drive shaft and the cable laying wheel can rotate synchronously with the stranding spindle at the same speed, thus achieving the purpose of cable laying without affecting the cable laying effect.

[0010] Specifically, the surface of the ground shaft is provided with splines along the central axis direction, and the pulleys of the first pulley group connected to the ground shaft are radially fixed and axially slidable on the ground shaft. By providing splines, the pulleys can be radially fixed to the ground shaft and axially slidable, thus not affecting the transmission or the wiring.

[0011] Preferably, the wiring mechanism further includes a second translation drive device, wherein the base is movably mounted on the frame along the central axis of the fixed shaft, and the second translation drive device drives the base to move.

[0012] Preferably, the stranding mechanism further includes a fixed base, a measuring wheel, and a guide wheel. The stranding spindle is rotatably mounted on the fixed base. The measuring wheel and the guide wheel are pivotally connected to the stranding frame. The stranding frame is connected to the stranding spindle. The center of the stranding spindle has an axial inlet hole. The lower wheel surface of the measuring wheel is tangent to the central axis of the inlet hole. The cable enters through the inlet hole and exits after sequentially winding around the measuring wheel and the guide wheel.

[0013] Preferably, the take-up drive mechanism further includes a second servo motor, a driving pulley, a driven pulley, and a drive belt. The second servo motor is mounted on the base and its output end is connected to the driving pulley. The driven pulley is connected to the take-up drive shaft, and the drive belt surrounds the driving pulley and the driven pulley.

[0014] Preferably, the cantilevered mobile wire winding single twister further includes a wire reel lifting mechanism, which is mounted on the frame and located between the twisting mechanism and the take-up drive mechanism. When assembling or disassembling the take-up reel, the wire reel lifting mechanism drives the take-up reel to rise or fall. Attached Figure Description

[0021] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please see Figures 1 to 3The cantilevered mobile single-twisting machine 100 of the present invention includes a twisting mechanism 1, a winding mechanism 2, a take-up reel 3, a take-up drive mechanism 4, and a frame 5.

The outer ring of the bearing is fixed to the cone sleeve. The cone sleeve abuts against the center of one side of the take-up reel 3. One end of the take-up drive shaft 41 abuts against the center of the other side of the take-up reel 3, and the take-up drive mechanism 4 drives the take-up reel 3 to rotate via the take-up drive shaft 41. The take-up drive shaft 41, take-up reel 3, and stranding spindle 11 are coaxially arranged. The cable laying mechanism 2 includes a cable laying drive device 21, a cantilever drive shaft 22, a cable laying wheel 23, a fixed shaft 24, a base 25, and a first translation drive device 26. One end of the fixed shaft 24 is fixed to the base 25. The fixed shaft 24 is tubular and has a through hole 241 passing through both ends. The take-up drive shaft 41 is coaxially and rotatably fitted into the through hole 24 of the fixed shaft 24, and both ends of the take-up drive shaft 41 extend out of the fixed shaft 24. Furthermore, the take-up drive shaft 41 and the fixed shaft 24 are axially fixed relative to each other. A deep groove ball bearing and a thrust roller bearing are sequentially arranged between the end of the take-up drive shaft 41 near the take-up reel 3 and the fixed shaft 24. A stop cone 411 is also fixedly connected to this end. The stop cone 411 abuts against the center of the other side of the take-up reel 3. The cantilever drive shaft 22 is coaxially sleeved around the fixed shaft 24; a bearing assembly 27 is provided between the cantilever drive shaft 22 and the fixed shaft 24 to support the fixed shaft 24; the cantilever drive shaft 22 is rotatable and axially sliding relative to the fixed shaft 24; a rotating frame 221 is provided at one end of the cantilever drive shaft 22, and cantilevers 222 are symmetrically arranged on the rotating frame 221; the cable guide wheel 23 is disposed on the cantilever 222 of the cantilever drive shaft 22 and located outside the take-up reel 3 to guide the cable 200 output from the stranding mechanism 1 to be wound onto the take-up reel 3. A pressure wheel 231 is provided on the cantilever 222, and the wheel surface of the pressure wheel 231 rolls against the wheel surface of the cable guide wheel 23 to prevent the cable 200 from detaching from the cable guide wheel 23. The first translation drive device 26 drives the cantilever drive shaft 22 to slide along its own axial direction; the cable laying drive device 21 drives the cantilever drive shaft 22 to rotate. The cable laying mechanism 2 also includes a movable seat 28, which is movably mounted on the frame 5 along the central axis of the cantilever drive shaft 22, and the cantilever drive shaft 22 is rotatably mounted on the movable seat 28 via a deep groove ball bearing.The cable laying drive device 21 is mounted on the movable base 28 and drives the cantilever drive shaft 22 to rotate. The first translation drive device 26 is mounted on the frame 5 and drives the movable base 28 to move along the central axis of the cantilever drive shaft 22. By setting the movable base 28, the cantilever drive shaft 22 can be slidably sleeved on the fixed shaft 24, thereby driving the cable laying wheel 23 to guide the cable 200 to be wound onto the take-up reel 3. The cable laying mechanism 2 also includes a second translation drive device (not shown in the figure). The base 25 is movably mounted on the frame 5 along the central axis of the fixed shaft 24, and the second translation drive device drives the base 25 to move. Please see Figures 3 to 5The bearing assembly 27 includes a bearing housing 271, a swivel bearing 272, and rollers 273. The bearing housing 271 is spaced between the cantilever drive shaft 22 and the fixed shaft 24. There are two swivel bearings 272, each located at one end of the bearing housing 271. Each swivel bearing 272 is a deep groove ball bearing. The swivel bearing 272 is fitted between the bearing housing 271 and the cantilever drive shaft 22. The inner ring of the swivel bearing 272 is fixed to the outer circumference of the bearing housing 271, and the outer ring of the swivel bearing 272 is fixed to the inner wall of the cantilever drive shaft 22. The rollers 273 are pivotally connected to the bearing housing 271 via a spindle 274 and are located below the fixed shaft 24 to support the fixed shaft 24 and to roll in contact with it. A gap 271a exists between the upper side of the outer wall of the fixed shaft 24 and the upper side of the inner wall of the bearing housing 271, allowing the fixed shaft 24 to be supported on the roller 273. Additionally, the inner wall of the bearing housing 271 is provided with a guide key 2711, and the front section of the fixed shaft 24 is provided with a guide groove 242. The guide key 2711 is slidably disposed within the guide groove 242 to guide the cantilever drive shaft 22 when it slides axially relative to the fixed shaft 24. By providing a rotating bearing 272 outside the bearing housing 271, the fixed shaft 24 and the cantilever drive shaft 22 are rotatably positioned relative to each other. Furthermore, by installing rollers 273 within the bearing housing 271, the cantilever drive shaft 22 supports the fixed shaft 24 and the take-up drive shaft 41. This provides an additional support point for the front end of the take-up drive shaft 41, preventing vibration caused by one end of the take-up drive shaft 41 and the fixed shaft 24 being suspended in the air, thus improving support rigidity and operational stability. Specifically, the cross-section of the roller 273 has an arc-shaped groove structure to contact and engage with the arc-shaped surface of the outer side of the fixed shaft 24. By utilizing the arc-shaped groove to engage with the outer side of the fixed shaft 24, the roller 273 and the fixed shaft 24 are in surface contact, increasing the contact area between the fixed shaft 24 and the roller 273, thereby making the support more stable and ensuring the stability of equipment operation. The rotation axis of the roller 273 is perpendicular to the central axis of the fixed shaft 24. This allows the roller 273 to roll when the cantilever drive shaft 22 moves axially, achieving rolling contact between the cantilever drive shaft 22 and the fixed shaft 24, effectively reducing frictional resistance.

[0023] Please see again Figure 2 and Figure 3The cable laying drive device 21 includes a first servo motor 211, a first pulley set 212, a ground shaft 213, and a second pulley set 214. The first servo motor 211 is mounted on the movable base 28 and its output end is connected to the cantilever drive shaft 22. The output end of the first servo motor 211 is connected to one end of the ground shaft 213 through the first pulley set 212 and drives the ground shaft 213 to rotate. The ground shaft 213 is mounted on the frame 5 and its other end is connected to the stranding spindle 11 through the second pulley set 214 and drives the stranding spindle 11 to rotate. By using the first pulley set 212, the ground shaft 213, and the second pulley set 214 to drive the stranding spindle 11, the cantilever drive shaft 22 and the cable laying wheel 23 can rotate synchronously with the stranding spindle 11 at the same speed, thus achieving the purpose of cable laying without affecting the cable laying effect. The surface of the ground shaft 213 is provided with splines along the central axis. The pulley of the first pulley assembly 212 connected to the ground shaft 213 is radially fixed and axially slidable on the ground shaft 213. By providing splines, the pulley can be radially fixed to the ground shaft 213 and axially slidable, thus not affecting the transmission or the wiring.

[0024] Please see again Figure 2 and Figure 6 The stranding mechanism 1 further includes a fixed base 12, a measuring wheel 13, and a guide wheel 14. The stranding spindle 11 is rotatably mounted on the fixed base 12. The measuring wheel 13 and the guide wheel 14 are pivotally connected to the stranding frame 15, which is connected to the stranding spindle 11. The guide wheel 14 is provided with another pressure wheel 141, the surface of which presses against the surface of the guide wheel 14 to prevent the cable 200 from detaching from the guide wheel 14. The center of the stranding spindle 11 has an axially oriented inlet hole 241. The lower surface of the measuring wheel 13 is tangent to the central axis of the inlet hole 241. The cable 200 enters through the inlet hole 241 and sequentially passes around the measuring wheel 13 and the guide wheel 14 before exiting.

[0025] Please see again Figure 2 and Figure 3 The take-up drive mechanism 4 further includes a second servo motor 41, a driving pulley 42, a driven pulley 43, and a drive belt 44. The second servo motor 41 is mounted on the base 25 and its output end is connected to the driving pulley 42. The driven pulley 43 is connected to the take-up drive shaft 41. The drive belt 44 surrounds the driving pulley 42 and the driven pulley 43.

[0026] Please see again Figure 1The cantilever 222 mobile wire-winding single twister also includes a wire reel lifting mechanism 6. The wire reel lifting mechanism 6 is mounted on the frame 5 and located between the stranding mechanism 1 and the take-up drive mechanism 4. When assembling or disassembling the take-up reel 3, the wire reel lifting mechanism 6 drives the take-up reel 3 to rise or fall. The wire reel lifting mechanism 6 can employ a servo motor and a lead screw and nut pair to drive the lifting platform, thereby using the lifting platform to raise or lower the take-up reel 3, saving manpower and improving the efficiency of assembling and disassembling the take-up reel 3.

[0027] Please also refer to Figure 2 and Figure 3 The first translation drive device 26 can adopt a structure of a third servo motor and a lead screw and nut assembly. The third servo motor is mounted on the frame 5, and its output end is connected to the nut of the lead screw and nut assembly. The nut is threadedly connected to the lead screw of the lead screw and nut assembly, and one end of the lead screw is connected to the movable seat 28. By driving the nut to rotate through the third servo motor, the nut causes the lead screw to translate, and the lead screw can then drive the movable seat 28 to translate. Similarly, the structure and principle of the second translation drive device are the same as those of the first translation drive device 26, and will not be described again.

[0028] In summary and in combination Figure 2 The working principle of the cantilevered moving cable winding single twister 100 of the present invention will be described in detail below: First, before operation, the empty take-up reel 3 is raised between the stranding drive shaft and the take-up drive shaft 41 using the reel lifting mechanism 6. Then, the second translation drive device is activated, which drives the base 25, the fixed shaft 24, and the take-up drive shaft 41 to move. The abutting cone 411 approaches and abuts against the center of one side of the take-up reel 3, while the center of the other side of the take-up reel 3 abuts against the top cone 111 of the stranding drive shaft. At this time, the stranding drive shaft and the take-up drive shaft 41 together clamp the take-up reel 3. Afterward, the cable 200 is pulled by a rotary traction machine external to the machine, and then the cable 200 is manually pulled onto the cantilevered moving single stranding machine 100. After passing through the inlet hole 241, the cable 200 wraps around the metering wheel 13 and the guide wheel 14. Then, after passing through the wire feeding wheel 23, it is initially wound onto the take-up reel 3.

[0029] After the cable pulling is completed, the rotary traction machine and the cantilevered moving cable winding machine 100 can be started to automatically twist and take up the cable. At this time, the cable 200 enters the inlet hole 241 of the cable winding mechanism 1 with constant tension. The first servo motor 211 of the cable winding drive device 21 drives the cantilever drive shaft 22 to rotate. At the same time, the first servo motor 211 drives the cable winding main shaft 11 to rotate through the first pulley group 212, the ground shaft 213 and the second pulley group 214. The cable winding main shaft 11 and the cantilever drive shaft 22 rotate synchronously to twist the cable 200 that has not entered the meter counting wheel 13. At the same time, the second servo motor 41 of the take-up drive mechanism 4 starts to drive the take-up drive shaft 41 to rotate. The take-up drive shaft 41 drives the take-up reel 3 to rotate. Therefore, the cable 200 is continuously output from the cable winding wheel 23 and wound on the take-up reel 3. In addition, while the cable is being wound up, the first translation drive device 26 drives the moving seat 28 to move back and forth, thereby driving the cantilever drive shaft 22 to move axially, which in turn causes the cable guide wheel 23 to move back and forth at both ends of the take-up reel 3. As a result, the cable 200 can be wound up evenly layer by layer on the take-up reel 3.

[0030] When the take-up reel 3 is full of cable 200, the cantilevered moving single twister 100 stops. At this time, the reel lifting mechanism 6 rises below the take-up reel 3. Then, the second translation drive device drives the base 25 to move, so that the base 25, the fixed shaft 24 and the take-up drive shaft 41 translate. The abutment cone 111 leaves the take-up reel 3, and the take-up reel 3 is unloaded onto the reel lifting mechanism 6. The reel lifting mechanism 6 then unloads the full take-up reel 3 and reinstalls a new take-up reel 3.

[0031] Compared with the prior art, the present invention arranges the stranding mechanism 1 on one side of the take-up reel 3, the take-up drive mechanism 4 on the other side of the take-up reel 3, and the cable laying mechanism 2 on the same side of the take-up drive mechanism 4, so that the cable laying mechanism 2 and the stranding mechanism 1 are arranged opposite to each other; and by setting a fixed shaft 24 and a seat 25, the take-up drive shaft 41 is sleeved in the fixed shaft 24, and the take-up drive shaft 41 abuts against the take-up reel 3, so that it can work with the stranding spindle 11 to clamp the take-up reel 3. Meanwhile, by sleeved cantilever drive shaft 22 around fixed shaft 24 and placing bearing assembly 27 between them, the bearing assembly 27 can support both fixed shaft 24 and take-up drive shaft 41, and also allow cantilever drive shaft 22 to rotate and slide axially relative to fixed shaft 24. Therefore, this arrangement provides stable support to the end of take-up drive shaft 41 near take-up reel 3, preventing large vibrations during rotation of take-up drive shaft 41 and take-up reel 3. This results in more even force distribution on each shaft and take-up reel 3, good support rigidity, and thus very stable and reliable operation, avoiding wear problems during long-term operation and effectively extending service life.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the scope of the present invention are still within the scope of the present invention.
