Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fully drawn yarns, in particular to a uniform cooling structure of ultra-high hollow flexible FDY fully drawn yarns. Background Art
[0002] In the textile industry, the production of fully drawn yarn (FDY) is an important link, and its quality directly affects the performance of the final product. Ultra-high hollow flexible FDY fully drawn yarn has excellent flexibility, high tensile strength and unique hollow structure, and is widely used in clothing, home textiles and industrial materials.
[0003] In the prior art, for example, the patent with publication number CN219951350U discloses a POY polyester yarn compact heat stretching device, in which a cleaning box is fixed on the side of the polyester yarn heating box and the stretching box, so that the polyester yarn can enter the polyester yarn heating box and the stretching box for stretching after being cleaned by the cleaning block inside the cleaning box, thereby ensuring that there is no large amount of dust on the surface of the polyester yarn before the stretching begins. After the polyester yarn is stretched, it passes through the cleaning block to clean the dust attached to the surface of the polyester yarn. After the polyester yarn is completely cooled, the dust cannot be removed, and a ventilation fan is fixed on the lower right side of the stretching box to drive the suspended dust to move downward, thereby reducing the possibility of adhering to the surface of the polyester yarn.
[0004] As described in the above patent, in the process of stretching textile yarns, the yarns are first heated and then stretched, and finally cooled to shape, while the traditional cooling method usually adopts water spray cooling or air cooling, but these methods are often difficult to achieve uniform cooling of ultra-high hollow flexible FDY fully stretched yarns. Water spray cooling may cause water droplets to remain on the surface of the yarn bundle, affecting the drying effect of the yarn; and the air cooling method may cause inconsistent cooling speed inside and outside the yarn bundle due to uneven wind speed or unstable wind temperature, which in turn causes excessive temperature difference between the inside and outside of the yarn, affecting the tensile performance and structural stability of the yarn. For this reason, the utility model provides a uniform cooling structure for ultra-high hollow flexible FDY fully stretched yarns. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a uniform cooling structure for ultra-high hollow flexible FDY fully stretched yarn, which solves the problem that traditional cooling methods usually adopt water spray cooling or air cooling, but these methods are often difficult to achieve uniform cooling of ultra-high hollow flexible FDY fully stretched yarn.
[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions: a uniform cooling structure of ultra-high hollow flexible FDY fully drawn yarn, including a cooling box, a cooling mechanism is arranged inside the cooling box, and the cooling mechanism includes:

[0008] The dehydration assembly is arranged on the upper part of the cooling box and is used for dehydrating the fully drawn yarn in the cooling box.

[0026] The dehydration assembly 22 is disposed on the upper portion of the cooling box 1 and is used to dehydrate the fully drawn yarn in the cooling box 1 .
[0027] By starting the motor 213 on one side, the motor 213 drives the drawing roller 212 to rotate after being powered on, and the two groups of drawing rollers 212 rotate in the same direction, and then the fully drawn wire is drawn. The triangular structure composed of the folding roller 214 and the two groups of drawing rollers 212 allows the fully drawn wire to be in full contact with the cooling water, and is evenly cooled by left and right traction (the specific model of the motor is AM34HD0404-08 stepper motor, which is a four-phase winding. When working, the order of the electric pulse signal applied to the winding is controlled. When the electric pulse signal is applied to the winding in the order of A→B→C→D, the motor will rotate in one direction, that is, forward rotation. If the phase sequence is changed and the electric pulse signal is applied in the order of A→D→C→B, the motor will rotate in the opposite direction, that is, reverse rotation).
[0028] In this embodiment, the dehydration component 22 includes a connecting rod 228 fixedly connected to one side of the support frame 211, and the other side of the connecting rod 228 is fixedly connected to a frame plate 221. A slide plate 222 is slidably installed on the inner wall of the frame plate 221. A limited slider 223 is integrally formed on both sides of the slider 222. A directional slide groove for the limited slider 223 to slide up and down is provided on both sides of the frame plate 221. The inner walls of the upper and lower ends of the frame plate 221 are fixedly connected to support columns 225, and a sleeve 224 is slidably sleeved on the outer wall of the support column 225. A compression spring 226 sleeved on the outside of the support column 225 is installed between the sleeve 224 and the frame plate 221. A water-absorbing roller 227 is installed between horizontally adjacent slide plates 222, and a positioning bar 229 is rotatably installed on the connecting rod 228. When the positioning bar 229 is rotated to a vertical position, it supports the upper and lower limit sliders 223. The positioning bar 229 is rotated to separate the support state between it and the limit slider 223. The compression spring 226 is previously in a compressed state. After releasing the limit slider 223, the water-absorbing roller 227 (the water-absorbing roller 227 is specifically composed of a central roller body and an absorbent cotton sleeve mounted on the outside) fits up and down to clamp the fully stretched yarn, so that the water droplets on its surface are wiped off when the fully stretched yarn is pulled.

By opening the valve, the cooling water in the cooling box 1 flows into the liquid storage tank 3. After the cooling box 1 is emptied, the fully stretched wire continues to be pulled by the motor 213.
[0030] In this embodiment, a control valve is installed on the first conduit 4 , and a pump is installed on the second conduit 5 .

After the motor 213 is powered on, it drives the drawing roller 212 to rotate, and the two groups of drawing rollers 212 rotate in the same direction, and then the fully stretched wire is pulled. The triangular structure composed of the folding roller 214 and the two groups of drawing rollers 212 enables the fully stretched wire to be fully in contact with the cooling water and is evenly cooled by left and right pulling. After cooling is completed, the cooling water in the cooling box 1 is opened by opening the valve, and then the cooling water in the cooling box 1 flows into the liquid storage tank 3. After the cooling box 1 is emptied, the fully stretched wire continues to be pulled by the motor 213. Before this, the positioning bar 229 is rotated to separate it from the supporting state between it and the limit slider 223. The compression spring 226 was previously in a compressed state. After releasing the limit slider 223, the water-absorbing roller 227 fits up and down to clamp the fully stretched wire, so that the water droplets on its surface are wiped off when the fully stretched wire is pulled.
