[0002] Cotton yarn cutting is a common process step in the textile and apparel industry, which refers to cutting or trimming cotton yarn according to design requirements and size specifications.

[0003] Cotton yarn cutting and straightening mechanisms play a key role in the textile and garment manufacturing process, ensuring that the cotton yarn remains flat and straight before cutting.

[0004] The existing cotton yarn cutting and straightening mechanism can usually only straighten the cotton yarn along a single X-axis or Y-axis direction. Although this unidirectional straightening method can improve the flatness of the cotton yarn to a certain extent, due to the complex fiber structure and internal stress distribution of the cotton yarn, the unidirectional straightening often cannot completely eliminate the wrinkles of the cotton yarn, especially when dealing with thicker or longer fiber cotton yarn, the effect of unidirectional straightening is even more limited.

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The two control seats 2 achieve precise straightening of the cotton yarn along the X-axis direction by synchronously approaching or moving away, thereby ensuring uniform stretching of the cotton yarn in the X-axis direction and effectively removing transverse wrinkles; the control seat 2 comprises: a lower positioning part 4 installed on the control seat 2; an upper positioning part 5 installed on the control seat 2, and configured to move closer to or away from the lower positioning part 4, and the upper positioning part 5 is used to move downward When the positioning part 4 is close, the cotton gauze is clamped and fixed, and the upper positioning part 5 moves downward to cooperate with the lower positioning part 4 to form a clamping structure, so that the cotton gauze can be firmly clamped. This clamping method is not only stable, but also suitable for cotton gauze of various thicknesses; the two leveling mechanisms 7 are respectively connected to the two ends of the upper positioning part 5, and are configured to apply a pulling force to the cotton gauze along the Y-axis direction of the cutting table 1 when the upper positioning part 5 approaches the lower positioning part 4, so as to straighten the cotton gauze along the Y-axis direction. After the cotton gauze is clamped, the leveling mechanism 7 applies a pulling force to the cotton gauze along the Y-axis direction, so as to further remove the wrinkles of the cotton gauze in the Y-axis direction, thereby achieving a comprehensive straightening effect.

[0048] Reference Figure 3 The upper positioning part 5 includes: a moving plate 501 connected to the control seat 2, a leveling mechanism 7 connected to the moving plate 501; and a positioning plate 502 installed at the bottom of the moving plate 501.

[0049] Reference Figure 3 and Figure 5 The leveling mechanism 7 includes: a swing plate 701, which is connected to the moving plate 501 and is configured to rotate on the moving plate 501; a connecting seat 702, which is connected to the swing plate 701; a stretching plate 703, which is installed on the connecting seat 702 and is configured to drive the connecting seat 702 to rotate on the swing plate 701 when the moving plate 501 moves downward. The swing plate 701 rotates on the moving plate 501. Through the linkage effect of the swing plate 701, the connecting seat 702 and the stretching plate 703, when the moving plate 501 moves downward, the cotton gauze is straightened in the Y-axis direction.

[0050] Reference Figure 4 The movable plate 501 includes: a first elastic member 503, which is connected to the movable plate 501, and the swinging plate 701 is connected to the first elastic member 503. The first elastic member 503 is used to provide a restoring force for the swinging plate 701 after rotation. The first elastic member 503 provides a restoring force for the swinging plate 701, ensuring that the leveling mechanism 7 can quickly return to the initial position after the action, and prepare for the next straightening operation. The first elastic member 503 adopts a clockwork spring, and can also adopt a coil spring.

[0051] Reference Figure 5 The connecting seat 702 includes: a second elastic member 704, one end of which is connected to the connecting seat 702, and the other end is connected to the swing plate 701. The second elastic member 704 is used to provide a restoring force for the connecting seat 702 after rotation. The second elastic member 704 provides a restoring force for the connecting seat 702, ensuring that the leveling mechanism 7 can quickly return to the initial position after the action, and prepare for the next straightening operation. The second elastic member 704 adopts a clockwork spring, and can also adopt a coil spring.

[0052] Reference Figure 2 The control seat 2 includes: a second power source 6 connected to the control seat 2, a power shaft of the second power source 6 is connected to the moving plate 501, and the first power source 3 provides the control seat 2 with moving power in the X-axis direction.

[0053] Reference Figure 1 , and also includes: two first power sources 3, which are installed on the cutting table 1, and the power shaft of the first power source 3 is connected to the control seat 2, and the second power source 6 drives the movable plate 501 to move up and down to achieve the clamping of the cotton gauze and the straightening in the Y-axis direction. The coordinated use of these two power sources makes the entire straightening process more automated and efficient. The first power source 3 and the second power source 6 both use cylinders, and linear motors can also be used.

[0054] Reference Figure 1 and Figure 2 , the projection shape of the control seat 2 is U-shaped.

[0055] During use, the cotton gauze to be cut is placed in the two control seats 2 to ensure that the cotton gauze is in contact with the lower positioning part 4, and the second power source 6 is started. The second power source 6 drives the movable plate 501 of the upper positioning part 5 to move downward, and the positioning plate 502 moves downward with the movable plate 501, and cooperates with the lower positioning part 4 to form a clamping structure to firmly clamp the cotton gauze. When the movable plate 501 moves downward, the swing plate 701 of the leveling mechanism 7 rotates on the movable plate 501, and the stretching plate 703 is squeezed, driving the connecting plate 502 to move downward. The receiving seat 702 rotates on the swing plate 701, and cooperates with the lower positioning part 4 to apply tension to the cotton gauze along the Y-axis direction of the cutting table 1. This process further removes the wrinkles of the cotton gauze in the Y-axis direction, and starts the two first power sources 3, which respectively drive the two control seats 2 to approach synchronously along the X-axis direction of the cutting table 1. As the control seats 2 approach, the cotton gauze is evenly stretched in the X-axis direction, effectively removing the lateral wrinkles and achieving a comprehensive straightening effect. When the cotton gauze is fully straightened, the cutting operation can be carried out.

[0056] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0057] By straightening along both the X-axis and the Y-axis simultaneously, wrinkles on the cotton gauze can be removed more comprehensively, and a more ideal straightening effect can be achieved, especially for thicker cotton gauze or cotton gauze with longer fibers.

[0058] Through the coordinated use of the first power source 3 and the second power source 6, the entire straightening process is automated and made more efficient, thereby reducing labor costs and improving production efficiency.

[0059] The design that combines clamping and leveling enables the mechanism to adapt to cotton gauze of different thicknesses and fiber lengths, and has strong adaptability and flexibility. The flatness of the cotton gauze that has been fully straightened has been significantly improved, which improves the cutting accuracy and reduces cutting errors and waste caused by uneven fabrics.
