Description

Technical Field

[0001] This utility model relates to the field of water-circulating yarn high-efficiency spray dyeing device, and more specifically, to a water-circulating yarn high-efficiency spray dyeing device. Background Technology

[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. It is divided into short fiber yarn and continuous filament yarn. Traditionally, after dyeing, yarn is usually squeezed by rollers to remove the residual dye liquor. When the rollers rotate, some of the squeezed dye liquor will be thrown back onto the squeezed yarn, which not only wastes the dye liquor but also makes it inconvenient to dry the yarn afterwards.

[0003] In existing technologies, such as the patent application CN217078011U, a water-circulating high-efficiency yarn dyeing device is disclosed, relating to the field of yarn dyeing technology. This device includes a dyeing box, a dye liquor box fixedly connected inside the dyeing box, a circulating pump fixedly connected inside the dye liquor box, and a water pipe fixedly connected to the output end of the circulating pump. This application utilizes a combination of structures such as extrusion plates, rotating rings, connecting rods, springs, and sliding rods. During use, the two extrusion plates are first separated, and then the yarn passes between the extrusion plates. After the extrusion plates are released, the two extrusion plates, under the elastic force of the springs, squeeze the yarn towards each other to dry the dye liquor. This avoids the problem of existing methods where residual dye liquor is removed from the yarn by roller extrusion. When the roller rotates, some of the squeezed dye liquor is thrown back onto the already squeezed yarn, resulting in waste of dye liquor and inconvenience for subsequent yarn drying.

[0004] In the aforementioned patent, the yarn is introduced into the extrusion plate during the spray dyeing process. The yarn passes between the extrusion plates, and after the extrusion plates are released, the two extrusion plates squeeze the yarn in opposite directions under the elastic force of the spring to squeeze out the dye liquor. However, in use, the extrusion plates rub against the yarn with hard friction, and the yarn has high friction when pulled, making it easy to break. In addition, the extrusion plates are located at the lower end of the spray dyeing mechanism, and after being squeezed dry, they are sprayed again, making it impossible to squeeze dry completely. Furthermore, the circulating pump is located inside and immersed in the dye, making it easy to be damaged and inconvenient to maintain. Utility Model Content
