Abstract
Description
Technical Field
[0001] This application relates to the technical field of dyeing and printing, and in particular to a yarn dyeing apparatus. Background Technology
[0002] Cone yarn is the product of the winding process in spinning mills in the textile industry. It is the yarn that falls from the spinning machine or twisting machine in the previous process. According to the requirements of the subsequent processes of yarn use in weaving factories, knitting factories, or towel factories, the yarn length is extended and defects and impurities on the yarn are removed. On the winding machine, it is rewound into a larger volume of cone yarn with or without edges, wound into a certain shape (such as conical or cylindrical), and with a certain winding density. It is commonly referred to as "cone yarn".
[0003] Depending on the color requirements of the packaged yarn processing, the packaged yarn needs to be dyed. Traditional packaged yarn dyeing equipment involves immersing the packaged yarn in dye and relying on the natural penetration of the dye to complete the dyeing process. During the dyeing process, the dye is in a static state, the dyeing time is relatively long, the penetration effect is poor, and the dye will settle due to prolonged static state, resulting in uneven dyeing.
[0004] Regarding the aforementioned technologies, the inventors believe that the dyeing process involves soaking the yarn in dye and allowing it to naturally penetrate, which requires a long dyeing time, results in poor penetration, and causes the dye to settle and precipitate, leading to uneven dyeing.

[0035] The cylinder body 2 and cylinder cover 3 together form the shell of the dyeing cylinder 1. The chassis 241, the lifting rod on the chassis 241 and the multiple sleeve rods 243 together form the yarn frame module 24 as a whole. The drive module 22 in the dyeing cylinder 1 provides power for the rotation of the rotating shaft 21. The chassis 241 is located above the support plate 23. The lifting rod 242 is set in the axial direction of the chassis 241. By acting on the lifting rod 242, the entire yarn frame module 24 can be moved.

The sleeve rod 243 is installed on the base 241 through the connection holes 2411. Workers can install multiple sleeve rods 243 according to the thickness of the yarn package 246, making better use of the space in the base 241. The dye can sequentially pass through the cavity of the support plate 23, the connecting pipe 248, and the cavity of the base 241, enter the connection hole 2411, and flow into the sleeve rod 243. The dye liquor flows through multiple flow holes 2431 to different heights on the yarn package 246 installed on the sleeve rod 243, gradually flowing to both sides of the yarn package 246 for dyeing, ensuring uniform dyeing and good penetration of the dye liquor.

The tank cover 3 is then closed, and the yarn cones 246 are dyed automatically within the tank 2. After dyeing, the tank cover 3 is opened, and the trolley removes the yarn frame module 24 to the next process unit via the hook 2421.
[0045] Several rollers 232 are installed at the bottom of the chassis 241. A rotating groove 231 is provided on the support plate 23.

The dye in the dyeing cylinder 4 is introduced into the base plate 241 through the support plate 23 and then transported to multiple sleeve rods 243 on the base plate 241. The dye flows through multiple flow holes 2431 on the sleeve rods 243 to the corresponding yarn packages 246, enabling layer-by-layer dyeing. The flow guiding component 247 inside the sleeve rods 243 guides the flow and distribution of the dye, ensuring that the dye can cover the entire yarn package 246, further ensuring the uniformity of dyeing. When a certain amount of dye is introduced into the dyeing cylinder 1, the rotating shaft 21... The rotational motion of the yarn carrier module 24 drives the overall rotational motion of the yarn carrier module 24, ensuring that the dye in the cylinder 2 does not settle, while accelerating and fully contacting the yarn package 246 with the dye, improving the penetration speed and effect, thereby reducing the dyeing time required, ensuring uniform dyeing, and improving the dyeing effect; the guide plate 2473 is wound inside the sleeve rod 243, which can guide the flow state of the dye liquor in the sleeve rod 243, so that the dye liquor can fully dye different positions of multiple yarn packages 246 on the sleeve rod 243, thereby covering the entire yarn package 246, ensuring the uniformity of dyeing, and improving the dye penetration speed and dyeing effect.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
