Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to a color-spun yarn fiber winding device for preventing loosening. Background Art

[0002] Colored spun fibers refer to fibers that are dyed into colored fibers, and then multiple colored fibers of different colors are fully mixed to synthesize fiber yarns with mixed color visual effects. Colored spun fibers use the process of dyeing first and spinning later, which shortens the production and processing process of enterprises, reduces production costs, and achieves cost reduction and efficiency improvement. After the colored spun fibers are synthesized, they need to be wound.

[0003] At present, the working principle of winding equipment is mostly to lead out the color-spun fiber and fix it to the self-reciprocating mechanism, so that the self-reciprocating mechanism reciprocates along the set path, thereby winding the color-spun fiber on the high-speed rotating winding disk. In this way, a roll of color-spun fiber is obtained. However, the obtained color-spun fiber will show the phenomenon of tight at both ends and loose in the middle. Because as far as the winding equipment is concerned, the color-spun fiber is introduced from the outside, when the self-reciprocating mechanism is located at both ends of the winding disk, the corresponding color-spun fiber leads out longer, and when the self-reciprocating mechanism is located in the middle of the winding disk, the corresponding color-spun fiber leads out shorter. Therefore, when the self-reciprocating mechanism moves from both ends to the middle, the color-spun fiber is not as tight as before, so the color-spun fiber finally obtained will show the phenomenon of loose in the middle.

The self-reciprocating mechanism 6 is driven by the driving rod 4 to reciprocate along the driving rod 4 and the guide rod 5 within the path range of the width of the winding disk 2; a top seat 7 is provided on the self-reciprocating mechanism 6, and a main motor 3 for driving the winding disk 2 to rotate is provided on the frame 1, and a driving rod 4 and a guide rod 5 are provided on the driving rod 4 and the guide rod 5. Two vertical rods 8 are opposite to each other in the length direction, and elastic adjustment components 9 are provided on the two vertical rods 8. The elastic adjustment components 9 include a fixed ring 10, a lower spring 11, an adjustment seat 12, an upper spring 13, and a movable ring 14. The fixed ring 10 is fixedly connected to the vertical rod 8, and the adjustment seat 12 is sleeved outside the vertical rod 8. The fixed ring 10 and the adjustment seat 12 are connected by the lower spring 11, and the movable ring 14 and the adjustment seat 12 are connected by the upper spring 13. A detection seat 15 is provided between the adjustment seats 12 of the two elastic adjustment components 9. The detection seat 15 The inner rotation is connected with a detection ring 16 for the colored spinning fiber to pass through, the rotating shaft of the detection ring 16 is parallel to the vertical rod 8 and a rotation angle sensor 17 is arranged at the rotating shaft, and an adjusting motor 18 is arranged above the two vertical rods 8, and the rotating shaft of the adjusting motor 18 is coaxially connected with a lead screw 19, and the movable ring 14 is transmission-connected to the lead screw 19. When the self-reciprocating mechanism 6 performs reciprocating motion, the rotation angle sensor 17 detects the position of the self-reciprocating mechanism 6 in real time, and the two adjusting motors 18 respond to the detection signal of the rotation angle sensor 17 and adjust the position of the self-reciprocating mechanism 6. When the position of the reciprocating mechanism 6 approaches the end of the winding disk 2, the movable ring 14 is driven to move downward along the lead screw 19, and when the position of the reciprocating mechanism 6 approaches the center of the winding disk 2, the movable ring 14 is driven to move upward along the lead screw 19; a guide wheel 20 is also provided on the top seat 7, and the guide wheel 20 is located behind the two vertical rods 8. A support rod 21 is also provided on the frame 1, and the support rod 21 is located above the center of the winding disk 2. A lead ring 22 is provided on the support rod 21, and the colored spun fiber passes through the lead ring 22, the detection ring 16, and the guide wheel 20 and is wound on the winding disk 2.

[0028] In the present embodiment, the winding disk 2 driving principle of the anti-loosening colored spun fiber winding device and the self-reciprocating mechanism 6 driving principle are consistent with the traditional principle. In order to solve the problem that the colored spun fiber will show the middle looseness, the anti-loosening colored spun fiber winding device accurately locates the starting point of the colored spun fiber adjustment by the lead ring 22, and all the colored spun fibers passing through the lead ring 22 are within the range of dynamic adjustment. After determining the starting point of the colored spun fiber, as the self-reciprocating mechanism 6 reciprocates along the driving rod 4 and the guide rod 5, the angle of the detection ring 16 caused by the colored spun fiber passing from the lead ring 22 to the detection ring 16 can be measured by the angle sensor 17. On the other hand, the detection ring 16 is elevated by the adjustment seat 12, and the height of the detection ring 16 is dynamically changed according to the detection value of the angle sensor 17. In the process of the position of the self-reciprocating mechanism 6 near the end of the winding disk 2, the movable ring 14 is driven to move downward along the lead screw 19, so that the height of the detection ring 16 is reduced. When the position of the self-reciprocating mechanism 6 approaches the center of the winding disk 2, the movable ring 14 is driven to move upward along the lead screw 19, so that the height of the detection ring 16 is increased. The lowering and raising processes are driven by the two regulating motors 18, and the height difference of the detection ring 16 is generated to overcome the problem of different tightness of the colored spun fiber when it reciprocates with the self-reciprocating mechanism 6. Therefore, the colored spun fiber finally obtained will not be loose in the middle.
