Background Art

[0002] As is well known, a direct twister is a yarn production device that combines two strands of silk threads and twists them into one strand.

[0004] To solve the above technical problems, it is necessary to provide an innovative direct twister with an actively rotating yarn equalizing device to overcome the defects in the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to the attached drawings in the specification Figure 1 to Figure 2 As shown, the present utility model is a direct twisting machine with an actively rotating yarn evenness regulator, which is used to twist an outer yarn 91 and an inner yarn 92 into a yarn 93, and it is composed of a frame 1, a spindle 2, an inner yarn tensioner 3, a yarn evenness regulator 4, an overfeed roller 5, a yarn guiding mechanism 6, a friction roller 7, a creel 8, etc.

[0018] Among them, the spindle 2, the inner yarn tensioner 3, the yarn evenness regulator 4, the overfeed roller 5, the yarn guiding mechanism 6, the friction roller 7 and the creel 8 are sequentially installed on the frame 1 from bottom to top.

[0019] The outer yarn 91 is placed on the top of the frame 1. The outer yarn 91 sequentially passes through an outer yarn tensioner 11 and a yarn turning tube 12 and enters the spindle 2, and a yarn balloon is formed by the driving of the spindle 2.

[0020] A spindle motor 21 is provided at the bottom of the spindle 2, and the spindle motor 21 can drive the spindle 2 to rotate. Since each spindle 2 is driven by an independent spindle motor 21, each spindle position can be independently controlled.

[0021] An inner yarn 92 is placed inside the spindle 2. The inner yarn 92 is wrapped by a yarn balloon formed by the rotation of the outer yarn 91 and is fed into the doubling twister 4 through the inner yarn tensioner 3.

[0022] The doubling twister 4 is installed on a mounting base 41. The mounting base 41 is fixed to the machine frame 1, and a doubling twister motor 42 is installed thereon. The doubling twister motor 42 can drive the doubling twister 4 to rotate, so that the doubling twister 4 can rotate actively. By the rotation of the doubling twister 4, the outer yarn 91 and the inner yarn 92 are combined and twisted.

[0023] In this embodiment, a pulley 43 is provided on both the doubling twister motor 42 and the doubling twister 4. The two pulleys 43 are connected by a synchronous belt 44, so that the doubling twister motor 42 drives the doubling twister 4 to rotate through the pulley 43 and the synchronous belt 44. Of course, the doubling twister motor 42 can also drive the doubling twister 4 through transmission methods such as gears and sprockets.

[0024] Furthermore, the rotational speed of the spindle motor 21 is matched with the rotational speed of the doubling twister motor 42, so that the rotational speeds of the spindle 2 and the doubling twister 4 are the same, ensuring that the twist of the yarn meets the processing requirements, and the quality of the yarn twisting is good. At the same time, it avoids the breakage of the outer yarn 91 or the inner yarn 92 caused by the inconsistent rotational speeds of the spindle 2 and the doubling twister 4.

[0025] A yarn bobbin 81 is clamped on the creel 8. The yarn bobbin 81 can be in contact with the friction roller 7, so that the friction roller 7 can drive the yarn bobbin 81 to rotate, thereby winding the twisted yarn 93 onto the yarn bobbin 81.

[0026] The working principle of the direct twister with an actively rotating doubling twister of the present utility model is as follows: The outer yarn 91 is sequentially conveyed by the outer yarn tensioner 11 and the yarn turning tube 12, and then enters the spindle 2; the spindle 2 is driven by the spindle motor 21 to make the outer yarn 91 rotate to form a yarn balloon; then, the outer yarn 91 enters the doubling twister 4. The inner yarn 92 is placed inside the spindle 2 and enters the doubling twister 4 after passing through the inner yarn tensioner 3. The doubling twister 4 rotates actively under the drive of the doubling twister motor 42, thereby combining and twisting the outer yarn 91 and the inner yarn 92 to form the yarn 93. The yarn 93 is sent to the yarn guiding mechanism 6 through the overfeed roller 5, and the yarn guiding mechanism 6 guides the yarn back and forth left and right. At this time, the friction roller 7 is in contact with the yarn bobbin 81, making the yarn bobbin 81 rotate, thereby winding the yarn 93 onto the yarn bobbin 81.

[0027] The direct twister with an actively rotating uniform twister of the utility model actively drives the uniform twister 4 through the uniform twister motor 42, enabling the uniform twister 4 to rotate actively without relying on the external yarn 91 to drive the uniform twister 4. As a result, the external yarn 91 is not easily broken, and the strength of the external yarn 91 is not easily damaged, and the equipment can produce finer or lighter yarns.

[0028] The above specific implementation manners are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
