Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, and in particular to a yarn winding mechanism. Background Art

[0002] In order to ensure the quality of the yarn and the smooth progress of subsequent processes, the processed yarn needs to be wound and reeled in an orderly manner. Specifically, the yarn processed by the previous process is introduced into the yarn guide device and guided to the surface of the package through the yarn guide hole or the yarn guide needle. Before the yarn enters the package, the tension of the yarn is adjusted by the tension control system to ensure that it is wound under an appropriate tensile state. The yarn guide device moves back and forth along the axial direction of the package under the action of the transverse movement mechanism, so that the yarn is evenly distributed on the surface of the package, forming a tight and regular package structure.

[0003] For example, the Chinese patent with application number CN202411037759.7 discloses a cutting-resistant yarn winding device with an adjustment mechanism, including a working frame, a servo motor is fixedly installed on the top surface of the working frame, a winding column is arranged on the top surface of the working frame, operating frames are fixedly installed on both sides of the working frame, and an adjustment frame is arranged inside the operating frame; a rotating mechanism for rotating the winding column is arranged on the top surface of the working frame; the yarn twisting is prevented by adjusting the tension state of the cutting-resistant yarn, so as to improve the winding effect of the cutting-resistant yarn. However, although the yarn twisting can be prevented by adjusting the tension state of the cutting-resistant yarn, the yarn is continuously wound on the winding column. With the change of the winding diameter, the axial tensile stress of the yarn will become higher and higher, especially at the alternation of adjacent interlayer yarns, which is prone to stress mutation. Under the gradual winding of the outer layer of yarn, the yarn will be tightly clamped on the winding column, affecting the arrangement neatness of the yarn and the convenience of unloading. Summary of the invention

[0004] In view of this, the purpose of the present invention is to propose a yarn winding mechanism to solve the technical problem that in the prior art, the yarn is continuously wound onto a winding cylinder. As the winding diameter changes, the axial tensile stress of the yarn will become higher and higher, especially at the alternation of adjacent layers of yarn, where stress is prone to sudden changes. As the outer layer of yarn is gradually wound, the yarn will be tightly clamped on the winding cylinder, affecting the neatness of the yarn arrangement and the convenience of unloading.

[0056] As the diameter of the yarn package on the winding rod 3 gradually increases, in order to maintain a constant linear speed, the real-time rotation speed of the rotating shaft 18 is controlled by the servo motor 15, and the rotation speed of each winding rod 3 on the regulating frame 2 is then controlled to slow down accordingly.

During the flipping and adjustment process of the horizontal and vertical states, the yarn passing through the rotatable threading head 10 can be kept in a tensioned state, and the yarn coils wound on each layer of the winding column 3 can be pressed against each other. At the alternation of adjacent interlayer yarns, the tensile stress of the outer layer yarn and the adjacent inner layer yarn are kept consistent, thereby ensuring the neatness of the yarn arrangement.

[0065] In this embodiment, a relief opening 24 is formed at the upper end of the connecting plate 21 , and the wire pushing frame 4 is slidably disposed in the relief opening 24 .

[0066] In this embodiment, the guide opening 7 is arranged obliquely upward on the side facing the tensioning plate 8. When the output end of the cylinder 19 is in an extended state, the sliding head 22 is placed at the highest point of the guide opening 7, the pushing frame is placed in the telescopic opening 5, and the tensioning plate 8 is in an upright flipped state.

[0067] In this embodiment, the yarn winding area is between the pushing frame and the tensioning plate 8 on the winding column 3. When the output end of the cylinder 19 is in a retracted return state, the sliding head 22 is placed at the lowest point of the guide opening 7, the wire pushing frame 4 extends out of the telescopic opening 5 and pushes the yarn to the yarn winding area, and the tensioning plate 8 is in a horizontally flipped state.

[0068] In this embodiment, when the tensioning plate 8 is in a horizontally flipped state, the upper end surface of the tensioning plate 8 does not exceed the upper end surface of the winding column 3 .

[0072] A guide rail 27, wherein the guide rail 27 is mounted on the work frame 1;

[0073] The sliding frame 28 is slidably disposed on the guide rail 27 . The sliding frame 28 is also threadedly mounted on the lead screw 26 . The yarn guide cylinder 11 is mounted on the sliding frame 28 .

[0074] When the yarn is wound, the drive component three can drive the yarn guide drum 11 to slide toward the side close to the winding column 3, that is, the output end of the servo motor 25 drives the lead screw 26 to rotate, and then drives the yarn guide drum 11 on the sliding frame 28 to slide along the guide rail 27. At this time, each tensioning plate 8 is in a horizontal state. For the winding area between the wire pushing frame 4 and the tensioning plate 8 on the winding column 3, the yarn will lose the limiting effect of the tensioning plate 8 and automatically transfer to the yarn guide drum 11 to complete the automatic unloading of the winding disk.
