[0019] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 and Figure 2 and Figure 3 As shown, a circular knitting machine center sleeve angle fine-tuning device includes a drive component 1, a measuring component 2 and a column 3. The drive component 1 and the measuring component 2 are arranged on the inner ring 4 of the large tripod, and the column 3 is arranged on the sleeve 5. The sleeve 5 can rotate on the inner ring 4 of the large tripod.

[0021] The drive assembly 1 includes a motor 11, a screw rod 12, a sleeve 13 and a slider 14. The screw rod 12 is connected to the driving end of the motor 11, the sleeve 13 is threadedly connected to the screw rod 12, and the sleeve 13 is connected to the slider 14. The motor 11 drives the screw rod 12 to rotate. When the screw rod 12 rotates, the sleeve 13 moves on the screw rod 12, and the sleeve 13 drives the slider 14 to move.

[0022] The slider 14 has a slide groove 15, and the column 3 extends into the slide groove 15. The slider 14 can push or push back the column 3. The slider 14 drives the column 3 to move to the set position. The slider 14 can also drive the column 3 to reset. The movement of the column 3 drives the sleeve 5 to rotate. The path of the column 3 moving in the slide groove 15 is a curve.

[0023] The measuring assembly 2 includes a first measuring block 21, a second measuring block 22, a displacement meter 23, a fine-tuning block 24 and an adjusting rod 25. The first measuring block 21 and the second measuring block 22 are slidingly arranged on the adjusting rod 25 at intervals. A movable cavity 26 is formed between the first measuring block 21 and the second measuring block 22. The column 3 passes through the movable cavity 26. The displacement meter 23 is movably arranged on the first measuring block 21, and the fine-tuning block 24 is movably arranged on the second measuring block 22. The fine-tuning block 24 is located within the measuring range of the displacement meter 23.

[0024] In the initial state, the column 3 is in contact with the first measuring block 21 or the second measuring block 22. When the slider 14 drives the column 3 to move, the column 3 drives the sleeve 5 to rotate, that is, the column 3 makes a circular motion in the slide groove 15, and at the same time, the column 3 makes a circular motion in the moving cavity 26. The column 3 pushes the first measuring block 21 or the second measuring block 22 to move, so that the distance between the first measuring block 21 and the second measuring block 22 becomes farther, and correspondingly, the distance between the fine-tuning block 24 and the displacement meter 23 becomes farther. The displacement meter 23 measures the farther distance between the fine-tuning blocks 24, and the displacement meter 23 displays the angle of rotation.

[0025] The driving assembly 1 also includes a base plate 16, the motor 11 is arranged on the base plate 16, the slider 14 is slidably arranged on the base plate 16, and the base plate 16 is arranged on the outer wall of the inner ring 4 of the cauldron. When the motor 11 drives the screw rod 12 to rotate, the sleeve 13 drives the slider 14 to move on the base plate 16.

[0026] The drive assembly 1 also includes a first support plate 17 and a second support plate 18. The first support plate 17 and the second support plate 18 are arranged on the base plate 16. The screw rod 12 is rotatably arranged on the first support plate 17 and the second support plate 18. The first support plate 17 and the second support plate 18 have a supporting function for the screw rod 12.

[0027] The driving assembly 1 also includes a first guide rod 31 and a second guide rod 32, which are arranged on the first support plate 17 and the second support plate 18. The slider 14 is slidably arranged on the first guide rod 31 and the second guide rod 32. When the sliding sleeve 13 drives the slider 14 to move, the slider 14 is prevented from deflecting. The first guide rod 31 and the second guide rod 32 have a guiding function for the slider 14.

[0028] The slider 14 is provided with an avoidance groove 141 , through which the screw rod 12 passes. The screw rod 12 is located between the first guide rod 31 and the second guide rod 32 , and there is no contact between the slider 14 and the screw rod 12 .

[0029] The driving component 1 also includes a first position sensor 161, a second position sensor 162, a first sensing plate 163 and a second sensing plate 164.

[0030] The first position sensor 161 and the second position sensor 162 are both connected to the motor 11 signal. When the slider 14 moves, when the first position sensor 161 detects that the first sensing plate 163 has moved to the set position, it means that the slider 14 has driven the column 3 to the set position, and the motor 11 stops driving at this time. If the second position sensor 162 detects that the second sensing plate 164 has moved to the set position, it means that the slider 14 has driven the column 3 to the set position, and the motor 11 stops driving again at this time.

[0031] like Figure 2 and Figure 4 As shown, the sleeve 13 includes an integrally formed thick portion 131 and a thin portion 132. The thick portion 131 is connected to the slider 14 through a screw.
