Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning production technology, and more specifically, to a coloring device for multi-colored elastic polyester yarn. Background Technology
[0002] Spinning, also known as chemical fiber forming, is a process in which polyester yarn is resistant to chemicals and frequent washing, reducing fading and discoloration of clothing. Hotel uniforms, stonewashed denim, sportswear, and children's clothing are all made of polyester yarn. Dyeing is an important step in the production of polyester yarn.
[0003] For example, the existing patent CN213389270U discloses a rapid dyeing device for polyester filament production. The device heats the dye with a heating plate to prevent the dye from solidifying. When a large amount of dye drips, a second motor is started. The second motor drives the lead screw to rotate. The lead screw controls the movement of the adjusting block, which in turn drives the scraper to move and push the dripping dye back into the dyeing tank. This allows for convenient dye recovery and avoids waste.
[0004] When dyeing the spinning yarn, the yarn is passed through the dyeing box. After prolonged immersion, the dyeing solution settles downwards, causing the color of the dyeing solution to fade and thus failing to achieve the desired effect.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in the related technologies, this utility model proposes a coloring device for multi-colored elastic polyester yarn to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A coloring device for multi-colored elastic polyester yarn includes a dyeing box, a support base at the bottom of the dyeing box, a cover plate movably connected to the top of the dyeing box, and through pipes for polyester yarn to pass through the openings on both sides of the dyeing box. A stirring shaft one and a stirring shaft two are symmetrically arranged and movably connected inside the dyeing box. The dyeing box is equipped with a stirring mechanism for driving the stirring shaft one and the stirring shaft two.
[0008] Preferably, the stirring mechanism includes a housing located on one side of the dyeing box, one end of stirring shaft one and stirring shaft two extending to the housing and fitted with driven gears, and a transmission gear meshing with the driven gears is provided inside the housing and between the two sets of driven gears.
[0009] Preferably, the transmission gear is movably connected to the housing via a drive shaft, and the housing contains a motor for driving the drive shaft.
[0010] Preferably, the first stirring shaft is provided with a vertically arranged stirring frame, and the second stirring shaft is provided with a horizontally arranged stirring frame.
[0011] Preferably, both sides of the first and second stirring racks are provided with a number of evenly distributed, inclined paddles.
[0012] Preferably, the dyeing chamber is provided with a mounting plate that is movably connected to the first stirring shaft and the second stirring shaft, and the mounting plate is movably connected to the first stirring shaft and the second stirring shaft via bearings.
[0013] Preferably, the bottom of the dyeing box is provided with a discharge pipe for draining liquid, and the discharge pipe is equipped with a valve.
[0014] The beneficial effects of this utility model are as follows: through the cooperative arrangement of stirring shaft one and stirring shaft two with the stirring mechanism, the motor drives the transmission gear to rotate and two sets of driven gears to mesh and drive stirring shaft one and stirring shaft two to rotate. Stirring shaft one and stirring shaft two drive stirring frame one and stirring frame two to rotate. Since stirring frame one and stirring frame two are arranged in a cross shape, stirring frame one and stirring frame two rotate alternately in the dyeing box to mix the dyeing liquid of elastic polyester yarn, avoiding the precipitation of the dyeing liquid of elastic polyester yarn, which would affect the dyeing of elastic polyester yarn.
