[0020] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0021] This application provides a spinning cooling channel device, which is installed below the side blowing device of the spinning production equipment for the drawn yarn to pass through.

[0022] like Figure 1 , 2 As shown, the cooling channel device includes an upper flange 1, a channel body 2, and a lower flange 3 arranged sequentially from top to bottom. The upper flange 1 is connected to the side blowing device. The channel body 2 includes an upper channel 21 and a lower channel 22 connected vertically. The cross-sectional area of ​​the lower channel 22 gradually decreases from top to bottom, and several circular through holes 23 are opened on the lower channel 22.

[0023] like Figure 1 , 3 As shown in Figure 5, the upper flange 1 is detachably connected to the top of the upper passage 21 by several screws 4, and the lower flange 3 is connected to the bottom of the lower passage 22 by argon arc welding.

[0024] like Figure 1 , 4 As shown, the upper passage 21 includes a pair of first side walls 211 arranged in front and back opposite each other and a pair of second side walls 212 arranged in left and right opposite each other. The second side walls 212 are perpendicular to the first side walls 211, the pair of first side walls 211 are parallel to each other, and the pair of second side walls 212 are parallel to each other.

[0025] The lower passageway 22 includes a pair of third sidewalls 221 arranged front-to-back and a pair of fourth sidewalls 222 arranged left-to-right. The fourth sidewalls 222 are perpendicular to the third sidewalls 221, the pair of third sidewalls 221 are parallel to each other, and the distance between the pair of fourth sidewalls 222 gradually decreases from top to bottom. The distance between the pair of second sidewalls 212 is greater than the distance between the pair of first sidewalls 211, and the distance between the pair of fourth sidewalls 222 is greater than the distance between the pair of third sidewalls 221. In this embodiment, the upper passageway 21 and the lower passageway 22 are a single piece.

[0026] A pair of first sidewalls 211 and a pair of second sidewalls 212 define a first channel with a rectangular longitudinal cross-section, and a pair of third sidewalls 221 and a pair of fourth sidewalls 222 define a second channel with a trapezoidal longitudinal cross-section. The first and second channels are connected to allow the yarn output from the spinning production equipment to pass through. The cross-sectional area of ​​the second channel in the lower passage 22 for yarn passage gradually decreases, causing the airflow velocity through the lower passage 22 to gradually increase.

[0027] like Figure 1 , 2 As shown, several circular through holes 23 are formed on a pair of third sidewalls 221. These circular through holes 23 are evenly arranged on the pair of third sidewalls 221, and all circular through holes 23 are of the same size. When the filament passes through the second channel, heat is rapidly dissipated through the circular through holes 23 on the lower passageway 22 along with the accelerated airflow, improving heat dissipation efficiency. This makes it easier for heat in the passageway body 2 to diffuse and cool down, effectively improving the cooling effect and stability of the passageway body 2.

Those skilled in the art should understand that this application is not limited to the above embodiments.
