Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of full-automatic covering yarn machines, in particular to a full-automatic covering yarn machine. BACKGROUND

[0002] The full-automatic covering yarn machine is a textile machine for producing covering yarn. The full-automatic covering yarn machine produces covering yarn with specific structure and performance by continuously rotating and winding the outer wrapping fiber filament on the core filament (such as spandex) being uniformly stretched, so that the outer wrapping yarn covers the core yarn in a spiral manner.

[0003] However, the spindle design of the covering yarn machine in the prior art has certain limitations. In actual production process, the diameter and length of the thread winding bobbin will change due to different production requirements, raw material specifications and processing technology, etc. However, the spindle structure of the widely used covering yarn machine is relatively fixed and cannot be flexibly adjusted according to the specific size of the thread winding bobbin.

[0004] When the diameter and length of the thread winding bobbin are not well adapted to the spindle, a series of problems will occur during the rotation of the thread winding bobbin driven by the spindle. On the one hand, due to the size mismatch, the cooperation between the spindle and the thread winding bobbin is not tight enough, which causes the thread winding to loosen easily during high-speed rotation. This loosening not only affects the winding quality of the yarn, causes the tension of the yarn to be unstable, and causes the tension to be uneven, thereby affecting the forming effect and performance of the covering yarn, but also can cause the thread winding to displace on the spindle or even separate from the spindle, affecting the continuity and stability of production, increasing the risk of equipment failure, and reducing production efficiency.

[0005] On the other hand, the thread winding on the spindle is also prone to up-and-down jumping. This is mainly because the structure of the spindle cannot fully adapt to the size change of the thread winding bobbin. During rotation, the thread winding is affected by centrifugal force and the force generated during yarn winding, etc., and cannot stably maintain at the predetermined position on the spindle, thereby causing up-and-down jumping. The jumping phenomenon also causes fluctuations in yarn tension, affects the uniformity and surface quality of the yarn, causes defects in the covering yarn such as thick and thin sections, increased hairiness, etc., and reduces the pass rate of the product.

The top of the second spring 20 is connected to the inner wall of the first telescopic groove 19, and the bottom of the second spring 20 is connected to a telescopic extrusion plate 21. The tension of the second spring 20 is greater than the contraction force of the first spring 10. The outer side surface of the telescopic extrusion plate 21 is provided with a protruding plate 22 which protrudes from a through groove arranged on the outer side surface of the extrusion plate 18 and is parallel to the outer side surface of the extrusion plate 18. The inside of the pressing block 16 and the first connecting plate 17 is provided with a second telescopic groove 24, and a third spring 26 is arranged in the second telescopic groove 24.

[0021] In actual use, when the spool is installed on the hollow spindle 5, the extrusion plate 18 connected to the first connecting plate 17 by the pressing block 16 is first removed from the cavity 9 by the pressing block 16, so that the extrusion plate 18 and the telescopic extrusion plate 21 cancel the extrusion of the top-holding block 11, and the first spring 10 shrinks the top-holding block 11 into the cavity 9 by the contraction force.

Further, the tension of the second spring 20 in the first telescopic slot 19 at the bottom of the extrusion plate 18 is greater than the tension of the first spring 10, so that the telescopic extrusion plate 21 will not shrink into the first telescopic slot 19 when it is lowered due to the extrusion of the top-holding block 11. Then, according to the length of the bobbin of the spool, the pressing block 16 is continuously pressed down, so that the pressing block 16 holds on the top surface of the spool. At this time, the bottom of the cavity 9 extrudes the telescopic extrusion plate 21, so that the telescopic extrusion plate 21 shrinks into the first telescopic slot 19 by a distance. Further, the lug plate 22 provided on the middle part of the outer side surface of the telescopic extrusion plate 21 is stretched out from the through slot starting from the middle part of the outer side of the extrusion plate 18, and is parallel to the outer side surface of the extrusion plate 18, so as to prevent the extrusion of the top-holding block 11 by the extrusion plate 18 and the telescopic extrusion plate 21 from being deviated. Then, the rotating ring 23 is loosened, so that the second connecting plate 25 in the second telescopic slot 24 stretches out the limiting plug 27 inside the second connecting plate 25 from the through hole inside the second telescopic slot 24, and inserts the limiting plug 27 into the corresponding fixed slot 28 on one side of the positioning clamping groove 15, so as to fix the pressing block 16 on the top of the bobbin of the spool, and limit the top of the bobbin of the spool, so as to prevent the bobbin of the spool from jumping up and down on the hollow spindle 5.
