The inclination of the cone section is preferably 45 degrees, and the top of the conical column is R-shaped. The first control head 211-1 and 211-2 and the second control head 221-1 and 221-2 are conical columns. The arrangement from the cone to the root of the column is: cone--column--slope--column. The inclination of the cone section and the slope is preferably 45 degrees, and the top of the conical column is R-shaped.

[0074] like Figure 7 , Fig. 9 As shown, the power device 5 includes a fourth cylinder 51 and a transmission device 52, and the transmission device 52 includes a driving wheel 521, a driven wheel 522, a section wheel 523, a support sleeve 524 and an anti-reverse block 525. The driving wheel 521, the section wheel 523 and the support sleeve 524 are all assembled on the main shaft 526. The section wheel 523 is fixedly connected to the driving wheel 521. The support sleeve 524 is fixedly connected by a first connecting rod 527 and a second connecting rod 528. The other end of the first connecting rod 527 is movably connected to the piston rod of the fourth cylinder 51. The second connecting rod 528 is fixedly connected to the piston rod of the fourth cylinder 51. The other end of 528 is movably connected with the anti-reverse block 525. When the fourth cylinder 51 extends, the support sleeve 524 drives the second connecting rod 528 to rotate under the action of the first connecting rod 527, and the second connecting rod 528 drives the anti-reverse block 525 to rotate in the downward direction. When the fourth cylinder 51 retracts, it drives the anti-reverse block 525 to push the section wheel 523 in the opposite direction, thereby driving the driving wheel 521 to rotate, and the driving wheel 521 drives the driven wheel 522 to drive the sprocket 11 to rotate. The section wheel 523 is provided with an L-shaped fitting structure matching the anti-reverse block.

[0075] Figure 8 As shown, the rotation of the sprocket 11 drives the control positioning members to have a spacing of H1, ensuring that the axis of the control positioning member 4 is aligned with the axis of the upper inner laminated yarn member 21 each time the control positioning member 4 stops.

[0076] Figure 7 As shown, under the action of the double group (circulation) time relay and the electromagnetic valve, when the fourth cylinder 51 extends, the first cylinder 23 and the second cylinder 24 extend downward, and the inner layer pressing yarn member 21 and the middle layer pressing yarn member 22 perform the yarn pressing movement.

[0077] Figure 7 , Figure 8 As shown, when the fourth cylinder 51 retracts, the first cylinder 23 and the second cylinder 24 retract upward and wait. Under the action of the double group (cycle) time relay and the solenoid valve, after the control positioning member 4 is in place, the fourth cylinder 51 extends out and continues to work, and this is repeated to achieve automatic yarn pressing.

[0078] The preferred embodiments 1 and 2 of the utility model both adopt the linkage cooperation of the transmission device and the power device, which can automatically transport the oblique tube dyeing yarn tube to the bottom of the yarn pressing device, automatically unload and collect the yarn after pressing, and complete the yarn pressing process fully automatically, with simple structure, easy operation and low labor intensity.

[0079] The yarn pressing device can automatically and instantly squeeze the inner and middle yarns of the dried oblique tube-dyed yarn tube, reducing the friction between the yarns, effectively avoiding yarn breakage in the subsequent process, increasing yarn production and quality, and improving economic benefits.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
