DETAILED DESCRIPTION

[0018] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0019] like Figures 1 to 3 As shown, the utility model provides a cantilever single twisting machine, which includes a base 1, a fixed base 2 installed at one end of the base 1, a main shaft 4 that rotates and passes through the fixed base 2 and is provided with a wire hole 3, a first rotation drive mechanism 5 installed on the base 1 or the fixed base 2 and used to drive the main shaft 4 to rotate, a twisting frame 6 installed at the inner end of the main shaft 4, a plurality of winding wheels 7 rotatably connected to the twisting frame 6, a wire arrangement wheel 8 rotatably connected to the free end of the twisting frame 6, a lifting platform 9 installed in the middle of the base 1 and located below the twisting frame 6, a moving base 10 slidably connected to the other end of the base 1, a translation drive mechanism 11 installed on the base 1 and used to drive the moving base 10 to translate, and a central shaft 1 that rotates and passes through the moving base 10 and is provided with a center hole 12 3. A rotating shaft 14 rotatably arranged in the center hole 12, a second rotating drive mechanism 15 installed in the movable base 10 and used to drive the center shaft 13 to rotate, a rotating driver 16 installed on the outer wall of the movable base 10 and used to drive the rotating shaft 14 to rotate, a wire drum seat 17 installed at one end of the center shaft 13 close to the twisting frame 6, a cap 18 detachably connected to the free end of the wire drum seat 17 and a transmission shaft 19 rotatably arranged in the wire drum seat 17 and coaxially connected to the rotating shaft 14, a stud 20 is provided at the free end of the transmission shaft 19, the cap 18 is threadedly connected to the stud 20, and the wire drum seat 17 can extend into the inner cavity of the twisting frame 6; preferably, the lifting platform 9 is embedded in the top surface of the base 1, and the rotating shaft 14 is rotatably arranged in the center hole 12 via a bearing.

[0020] In actual application, the wire drum is installed on the wire drum seat 17, and the cap 18 is threadedly connected to the stud 20 to lock the wire drum on the wire drum seat 17. At this time, the wire drum is located in the inner cavity of the twisting frame 6. The multiple wires to be twisted pass through the wire hole 3 and are wound around several winding wheels 7. Then they are wound around the wire arrangement wheel 8 and are wound on the wire drum. Then the first rotation drive mechanism 5 drives the main shaft 4 to rotate, and the rotating main shaft 4 drives the twisting frame 6 to rotate. The rotating twisting frame 6 twists the multiple wires into a cable. At the same time, the second rotation drive mechanism 15 drives the central shaft 13 to rotate, and the rotating central shaft 13 drives the wire drum seat 17 and the wire drum to rotate. The rotating wire drum reels the twisted cable. In the process of the wire drum reeling the cable, the translation drive mechanism 11 drives the movable seat 10 to move back and forth together with the central shaft 13, the wire drum seat 17 and the wire drum to arrange the cables neatly on the wire drum. When the wire drum needs to be replaced, the table top of the lifting platform 9 rises and supports the wire drum, and then the rotating driver 16 drives the rotating shaft 14 and the transmission shaft 19 to rotate forward synchronously. The stud 20 on the forward transmission shaft 19 is threadedly connected with the cap 18 in a positive direction to loosen the cap 18 so that the cap 18 is removed from the wire drum seat 17. At this time, the translation drive mechanism 11 drives the moving seat 10 together with the central axis 13 and the wire drum seat 17 to move away from the twisting spin frame 6 until the wire drum seat 17 is pulled out of the inner hole of the wire drum, and then the lifting platform 9 is lowered until the table top of the lifting platform 9 is flush with the top surface of the base 1, the wire drum can be moved away from the twisting spin frame 6, and then the new wire drum can be moved to the lifting platform 9. On the table of the lowering platform 9, the table of the lifting platform 9 raises the new wire reel until the inner hole of the wire reel is aligned with the wire reel seat 17, and then the translation drive mechanism 11 drives the moving seat 10 together with the central axis 13 and the wire reel seat 17 to move in the direction close to the twisting frame 6 until the wire reel seat 17 is inserted into the inner hole of the wire reel, and then the cap 18 is aligned with the stud 20. At this time, the rotation driver 16 drives the rotating shaft 14 together with the transmission shaft 19 to reverse, and the stud 20 on the reversed transmission shaft 19 is reversely threaded with the cap 18 to tighten the cap 18 so that the cap 18 locks the wire reel on the wire reel seat 17 to complete the disassembly and assembly of the wire reel, and finally the table of the lifting platform 9 is lowered and reset. The utility model raises and lowers the wire reel by the lifting platform 9, and tightens or loosens the cap 18 by electric means, which greatly reduces the labor intensity of the operator and improves the efficiency of replacing the wire reel.

[0021] Specifically, the rotation driver 16 can adopt a motor, the translation drive mechanism 11 can adopt a screw module, and the first rotation drive mechanism 5 and the second rotation drive mechanism 15 can both be composed of a motor, a differential, a transmission belt and a transmission wheel, which will not be repeated here.

[0022] In this embodiment, the inner end surface of the reel seat 17 is concavely provided with a plurality of limiting guide holes 21, and the cap 18 is convexly provided with a plurality of limiting guide posts 22. The plurality of limiting guide holes 21 are respectively provided in a one-to-one correspondence with the plurality of limiting guide posts 22, and the limiting guide posts 22 are slidably inserted into the limiting guide holes 21. When the stud 20 rotates, since the limiting guide posts 22 are inserted into the limiting guide holes 21, the cap 18 does not rotate synchronously with the stud 20, but only moves along the stud 20, ensuring that the cap 18 can be tightened or loosened.

[0023] In this embodiment, the twisting frame 6 is U-shaped, with its opening facing downward toward the movable seat 10. Several winding reels 7 are evenly distributed within the twisting frame 6. The free end of the twisting frame 6 is also rotatably connected to a counterweight wheel 23. The counterweight wheel 23 and the wire arrangement wheel 8 are symmetrically positioned at the two free ends of the twisting frame 6. This structural design ensures good dynamic balance during rotation of the twisting frame 6.

[0024] In this embodiment, a first brake disc 24 is sheathed around the central shaft 13, and a first brake 25 is mounted on the movable base 10. The first brake 25 is used to brake the first brake disc 24. When the machine is shut down or the reel needs to be replaced, the first brake 25 brakes the first brake disc 24 to prevent the central shaft 13 from accidentally rotating.

[0025] In this embodiment, the main shaft 4 is sheathed with a second brake disc 26, and the fixing base 2 is equipped with a second brake 27. The second brake 27 is used to brake the second brake disc 26. The second brake 27 brakes the second brake disc 26 to prevent the main shaft 4 from accidentally rotating, thereby preventing the twisting frame 6 from accidentally rotating.

[0026] In this embodiment, the reel seat 17 is provided with a through hole 28 , which is coaxially connected to the center hole 12 , and the transmission shaft 19 is rotatably disposed in the through hole 28 via a bearing.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
