Technical Field
[0001] This utility model relates to the field of twisting machine technology, and in particular to a high-tension forced twisting machine. Background Technology
[0002] A twisting machine is a textile machinery device that twists multiple strands of fine yarn into one. Its function is to process yarn or combined yarn products into thread-like products for weaving and knitting. It consists of a twisting machine body and an electrical circuit. The spindles outside the twisting machine body are connected to the motor output shaft of the electrical circuit.

[0037] The retwisting unit 002 includes a retwisting mounting frame 5. The upper part of the retwisting mounting frame 5 is provided with multiple electric roller assemblies 6 corresponding to each set of forced twisting mechanisms 3. The bottom of the retwisting mounting frame 5 is provided with a mounting plate 8. The mounting plate 8 is provided with a take-up frame 10 corresponding to each electric roller assembly 6. A motor 9 is provided on one side of the take-up frame 10. The motor 9 drives the take-up roller of the take-up frame 10 to rotate.
[0038] The forced twisting mechanism 3 includes a roller rocker arm shaft 31, which is rotatably mounted on the initial twisting mounting frame 1. A roller 32 is mounted on the shaft of the roller rocker arm shaft 31 away from the initial twisting mounting frame 1.

A general-purpose motor 4 for driving the rotation of the roller rocker arm shaft 31 is mounted on the upper end of the frame.
[0039] In addition, the roller rocker arm shaft 31 includes a cavity 311 opened in the middle of the shaft body, a guide wheel 312 is rotatably arranged in the cavity 311, and a yarn feeding channel 313 is opened through one side of the cavity 311. The guide wheel 312 facilitates the yarn to be guided to the roller.
[0040] Furthermore, a bearing seat 315 is rotatably mounted on the other end of the roller rocker arm shaft 31 away from the initial twisting mounting frame 1. The bearing seat 315 is mounted on the suspension plate 33, and a connecting flange 37 is mounted on one side of the bearing seat 315. A threading head 36 is provided at the center of the connecting flange 37. A center sleeve 314 is provided on the outer wall of the middle part of the roller rocker arm shaft 31. A roller 32 is provided on the center sleeve 314. The roller 32 facilitates the increase of yarn stroke, thereby effectively increasing the tension of the yarn when it is twisted on the roller.
[0041] In addition, the yarn breakage alarm mechanism 2 includes a yarn breakage alarm component 23. A first yarn guide component 21 is arranged above the yarn breakage alarm component 23, and a second yarn guide component 22 is arranged on one side of the first yarn guide component 21. The first yarn guide component 21 and the second yarn guide component 22 are located on the same horizontal plane. Both the first yarn guide component 21 and the second yarn guide component 22 are composed of existing yarn guide hooks and yarn guide wheels, which facilitates the guidance of yarn.
[0042] Furthermore, the yarn breakage alarm component 23 includes a rotating seat 232, which is installed on both sides of the front frame of the initial twisting mounting frame 1. A tension swing rod 231 is rotatably mounted on the rotating seat 232, and a swing rod tension shaft 233 is connected to the tension swing rod 231. The swing rod tension shaft 233 extends into the interior of the front frame of the initial twisting mounting frame 1. A U-shaped limiting rod 24 is provided on the outside of the tension swing rod 231. The U-shaped limiting rod 24 is installed on the side wall of the front frame of the initial twisting mounting frame 1, and the U-shaped limiting rod 24 can play a good limiting role.
[0043] In addition, the electric roller assembly 6 includes a mounting box 61, which is installed on the upper part of the retwisting mounting frame 5. A rotary motor 7 is installed inside the mounting box 61. A first traction wheel 62 and a second traction wheel 63 are symmetrically rotatably arranged on one side wall of the mounting box 61. A guide wheel frame 64 is provided on the upper part of the mounting box 61 where the first traction wheel 62 is located. The first traction wheel 62 and the second traction wheel 63 facilitate the traction function.
[0044] Furthermore, a third gear 71 is mounted on the output end of the rotary motor 7. The third gear 71 is located between the first traction wheel 62 and the second traction wheel 63. The rotary motor 7 drives the first traction wheel 62 and the second traction wheel 63 to rotate. The first traction wheel 62 includes a first gear 621, which is located on one side of the third gear 71 and meshes with it. The second traction wheel 63 includes a second gear 631, which is located on the other side of the third gear 71 away from the first gear 621 and meshes with it. The rotary motor 7 enables the automated rotation of the roller.
[0045] In this embodiment, after the yarn comes out of the unwinding frame 35, it is first guided by the guide plate 34 to the hole on the threading head 36, and then enters the yarn feeding channel 313. After coming out of the yarn feeding channel 313, it is connected to the corresponding yarn breakage alarm mechanism 2 through the guide wheel 312. During this process, the yarn will come into contact with the roller 32, so that when the roller rocker arm shaft 31 rotates, the roller 32 can increase the yarn stroke, thereby increasing the yarn tension.
[0046] When the yarn enters the yarn breakage alarm mechanism 2, it is guided by the first guide yarn assembly 21 and the second guide yarn assembly 22 to the lower yarn breakage alarm assembly 23. The yarn will wrap around the guide yarn wheel of the tension swing rod 231. The tension swing rod 231 can be adjusted in distance via the rotating seat 232, thereby changing the yarn tension. Originally, the tension swing rod 231 rests on the bottom of the U-shaped limit rod 24. During the twisting process, the yarn will pull the tension swing rod 231 to swing upward, placing it at the top. Once the yarn breaks, it will detach from the tension swing rod 231. At this time, without the pull, the tension swing rod 231 will fall and rest on the U-shaped limit rod 24. The tension shaft 233 of this swing rod will rotate and change position. An alarm device that will sound when the tension shaft 233 rotates to a specified position can be connected to the tension shaft 233. Thus, when the tension swing rod 231 falls and rotates, the alarm device can sound and stop the machine, promptly alerting the surrounding operators to conduct timely inspections.
[0047] The yarn coming out of the yarn breakage alarm mechanism 2 will first pass through the uppermost guide wheel of the guide wheel frame 64, then pass through the second traction wheel 63 to the first traction wheel 62, and then be guided by another guide wheel of the guide wheel frame 64 to the lower winding frame 10. The winding frame 10 is driven by the motor 9 to wind up the twisted yarn.
[0048] During the winding process, the rotary motor 7 rotates, driving the third gear 71 to rotate, thereby enabling the first gear 621 and the second gear 631 on both sides to rotate actively, thus performing traction work. Compared with semi-automatic rollers, this automatic rotating roller makes traction smoother and has a longer service life. Compared with semi-automatic rollers, this automatic roller can further prevent yarn wear.
[0049] In this invention, by setting a roller 32 at the unwinding frame 35 where the yarn is released, the tension of the yarn is increased, thereby ensuring that the yarn will not loosen during twisting. The yarn breakage alarm mechanism 2 on one side can effectively detect the yarn breakage in time, thereby triggering an alarm and stopping the machine. Moreover, the yarn breakage alarm component 23 also has the effect of increasing tension. The roller located above the winding frame 10 is set to be electric, driven by the rotary motor 7 to rotate actively, thereby preventing the yarn from being worn when it passes through the roller assembly.
[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
