[0029] Embodiment 1

[0030] Combined with Figure 1 , Figure 5 and Figure 6 , an anti-knotting textile yarn rack with adaptive tension, comprising a spun yarn 1, a base 2 and a bracket 3 connected to the base 2, the base 2 is rotatably connected with a plurality of positioning shafts 4, the positioning shafts 4 can cooperate with a plurality of winding drums 5 with different diameters, the positioning shafts 4 are a multi-layer cylindrical stepped structure, the through holes 15 are evenly arranged in an array along the axis direction of the positioning shaft 4, the base 2 is connected with a positioning component for positioning the winding drum 5, the positioning component includes a cavity 13 connected to the base 2, the base 2 is connected with an air inlet pipe 14 on the side away from the positioning shaft 4, the positioning shaft 4 is hollow and communicated with the cavity 13, and the positioning shaft 4 is evenly arranged in an array circumferentially A plurality of through holes 15 are connected, and a limiting bead 16 is provided in the through hole 15 through a spring connection. A spring seat for spring installation is connected to the inner side of the through hole 15, and a gap is reserved on the spring seat for gas to pass through. A limiting groove 17 cooperating with the limiting bead 16 is relatively connected on the inner wall of the winding drum 5; a winding drum 5 is provided on the positioning shaft 4, and a telescopic cylinder 6 is connected between the two positioning shafts 4 on the bracket 3, and a connecting frame 7 is connected to the power end of the telescopic cylinder 6, and guide rods 22 are respectively connected on both sides of the connecting frame 7 or on the outer shell 8, and the guide rods 22 are slidably arranged through the bracket 3, and guide components are respectively connected at both ends of the connecting frame 7;

[0031] By setting the positioning shaft 4 and the positioning assembly in the above structure, the winding drum 5 with different inner diameters can be positioned by the positioning shaft 4, which not only improves the application range of the positioning shaft 4, but also prevents the winding drum 5 from sliding relative to each other during the winding process and affecting the winding effect.

[0032] Combined with Figure 5 A driving assembly that can drive the positioning shaft 4 to rotate synchronously is connected to the base 2, and the driving assembly includes a motor 18 connected to the base 2. The power output end of the motor 18 rotates and seals through the base 2 and is connected to a driving wheel 19 in the cavity 13. The positioning shaft 4 extends into the cavity 13 and is connected to a driven wheel 20 at one end. A synchronous belt 21 is respectively connected between the driving wheel 19 and the adjacent driven wheel 20, and between the adjacent driven wheels 20.

[0033] The arrangement of the driving assembly facilitates the multiple positioning shafts 4 to drive the winding drums 5 to perform winding operations synchronously, thereby improving the winding efficiency.

[0034] Embodiment 2

[0035] Based on the first embodiment, combined with the attached Figure 2 , Figure 3 , Figure 7 and Figure 8 The guide assembly includes a shell 8 connected to the end of the connecting frame 7 and a self-tensioning assembly. The shell 8 is rotatably connected to the top and bottom of the self-tensioning assembly respectively with guide wheels 9. The spun yarn 1 passes through the shell 8 and passes around the guide wheel 9 and the self-tensioning assembly and is connected to the winding drum 5 at the end. The self-tensioning assembly includes a U-shaped frame 10 that slides through the middle of the shell 8. A tensioning wheel 11 is rotatably connected to the U-shaped frame 10. The middle of the guide wheel 9 and the tensioning wheel 11 are respectively connected with an annular wire groove 30. The U-shaped frame 10 is sleeved with a first spring 12 on both sides. The shell 8 is connected with a fine-tuning assembly that can adjust the tension of the self-tensioning assembly.

[0036] The coordinated arrangement of the self-tensioning component and the fine-tuning component facilitates maintaining the appropriate tension of the spun yarn 1 during the winding process, thereby preventing the spun yarn 1 from being broken due to excessive tension or being collapsed due to excessive looseness.

[0037] Combined with Figure 3 , Figure 7 and Figure 8 The fine-tuning assembly includes an adjusting block 23 that slides with the tensioning wheel 11, and the adjusting block 23 is rotatably connected to a side of the tensioning wheel 11 with a plurality of balls 29, and a U-shaped plate 24 is slidably connected to the outside of the adjusting block 23, and ear plates 31 are respectively connected to both sides of the U-shaped plate 24, and the U-shaped frame 10 slides through the ear plate 31, and the first spring 12 is connected between the U-shaped frame 10 and the ear plate 31, and a second spring 25 is connected between the U-shaped plate 24 and the adjusting block 23, and a connecting pipe 26 is connected to the U-shaped plate 24, and the connecting pipe 26 slides through the shell 8 and is provided with a threaded tube 27 with an end seal at the end through a threaded connection, and the adjusting block 23 is connected to a push rod 28 on the inner side of the second spring 25, and the other end of the push rod 28 penetrates the connecting pipe 26 and abuts against the threaded tube 27 at the end.

[0038] The length of the first spring 12 can be adjusted through the fine-tuning component, thereby changing the extension and contraction degree of the tensioning wheel 11 after being stressed, thereby facilitating fine-tuning of the adaptive tension.

[0039] The specific usage is as follows:

[0040] The winding drum 5 is sleeved on the outside of the corresponding positioning shaft 4 step, and the spring drives the limiting bead 16 to pass through the through hole 15 and cooperate with the limiting groove 17 on the winding drum 5, so that the positioning shaft 4 can temporarily position the winding drum 5, and then by ventilating the air inlet pipe 14, the air pressure in the cavity 13 increases and drives the limiting bead 16 outward and seals with the through hole 15, and engages with the limiting groove 17 of the winding drum 5 to prevent the winding drum 5 from sliding relative to each other during the driving process of the driving component and affecting the winding effect.

[0041] By starting the motor 18, the motor 18 drives the driving wheel 19, and the driving wheel 19 drives the driven wheel 20 to rotate synchronously through the synchronous belt 21, so as to facilitate the multiple positioning shafts 4 to drive the winding drum 5 to perform the winding operation synchronously. The reciprocating extension and contraction of the guide component and the telescopic cylinder 6 can also guide the spun yarn 1, so that the spun yarn 1 can be evenly wound on the winding drum 5 during the winding process, thereby improving the uniformity of the winding.

[0042] In a natural state, the spun yarn 1 passes through the outer shell 8 and is wound between the guide wheel 9 and the tensioning wheel 11, and the tensioning wheel 11 can automatically realize tension adjustment through the first spring 12 and the sliding penetration cooperation between the U-shaped frame 10 and the outer shell 8; the length of the first spring 12 can be adjusted to change its stiffness through the setting of the fine-tuning component, and then the telescopic degree of the tensioning wheel 11 can be fine-tuned to meet the needs of use, by rotating the threaded cylinder 27, the threaded cylinder 27 is connected with the connecting tube 26 by a thread and rotates while moving along the direction of the connecting tube 26, because the push rod 28 is always against the inner bottom wall of the threaded cylinder 27 under the action of the second spring 25, as the threaded cylinder 27 moves, the push rod 28 drives the adjustment block 23 to move along the direction of the push rod, and then the length of the first spring 12 is adjusted to keep the spun yarn 1 at a suitable tension during the winding process, to avoid the situation where the spun yarn 1 is too tight and broken or too loose and collapsed.
