Description

Technical Field

[0001] This utility model relates to the technical field of yarn dyeing equipment, specifically to a baking and color-fixing device for yarn dyeing. Background Technology

[0002] After dyeing, yarn needs to be fixed and dried to ensure the color fastness. Yarn dyeing drying and fixing equipment is an important piece of equipment in the textile printing and dyeing industry for completing the color fixing treatment after yarn dyeing. Its main function is to raise the temperature of the fabric through dry hot airflow, so that the dye and yarn fibers can react chemically, thereby making the dye firmly bonded to the yarn fibers, so as to improve the color fastness and stability of the dyed products.

[0003] The existing baking and color-fixing equipment for yarn dyeing has a relatively simple structure. The baking and color-fixing equipment directly blows the yarn to dry it. Since the yarn is absorbent, a lot of dyeing liquid will adhere to the yarn. Using only hot air drying is slow, time-consuming and has poor drying effect, which will reduce the color-fixing effect of the yarn. Therefore, in order to solve the above problems, a baking and color-fixing equipment for yarn dyeing is proposed. Utility Model Content

The drain pipe 28 can guide the dyeing liquid into the waste liquid pool. The guide plate 23 is trapezoidal in frontal view and inverted teardrop shape in side view. The guide plate 23 is composed of a metal plate and an elastic rubber strip fixedly connected to the upper end of the metal plate.

The lower end face of the first limiting seat 31 is in contact with the upper end face of the second limiting seat 33. The first extrusion roller 32 and the second extrusion roller 36 are both metal rollers and covered with a metal plate. The outer rubber coating layer of the roller is formed. The dyeing liquid in the yarn can be squeezed out by the first extrusion roller 32 and the second extrusion roller 36 without causing excessive compression to the yarn. The center of the first extrusion roller 32 and the center of the second extrusion roller 36 are both located on the vertical central axis of the guide plate 23 in the side view. The upper end of the elastic rubber strip of the guide plate 23 is in contact with the lower end of the rubber coating layer of the second extrusion roller 36. The upper end of the rubber coating layer of the second extrusion roller 36 is in contact with the lower end of the rubber coating layer of the first extrusion roller 32. The dyeing liquid can be collected in the collection tank 21 by the first extrusion roller 32, the second extrusion roller 36 and the guide plate 23.

[0030] Work process: This device needs to be connected to the yarn dyeing production line. The device should be installed on the discharge port side of the yarn dyeing device. The device needs to provide power for the movement of the yarn through the yarn traction device. The device needs to treat the waste gas generated during drying through the yarn dyeing waste gas treatment device. Before use, the power should be turned on and the exhaust port of the exhaust fan 17 should be connected to the yarn dyeing waste gas treatment device. The lower pipe of the drain pipe 28 should be connected to the waste liquid pool. The device is equipped with an external controller. The external controller of the device is electrically connected to the hot air blower 15, the exhaust fan 17, and the switching valve 27 respectively. The operating status of the hot air blower 15, the exhaust fan 17, and the switching valve 27 can be adjusted by manually operating the external controller. All of the above are existing technologies.When using this device, the operator first introduces multiple dyed yarns into the fixing chamber 12 through the opening on the rear side of the fixing chamber 12. The yarns pass between the first compression roller 32 and the second compression roller 36, then around multiple support rollers 14, and finally exit the fixing chamber 12 through the opening on the front side of the fixing chamber 12. The ends of the yarns are then fixed to the yarn traction device, which moves the yarns from back to front and winds them around the yarn traction device. Subsequently, the operator starts the hot air blower 15 and the exhaust fan 17 via an external controller. The moving yarns are first squeezed by the elastic rubber coating of the first compression roller 32 and the second compression roller 36. Since the first squeezing roller 32, which is limited by the first limiting seat 31, cannot move up or down, while the sliding seat 35, which is limited by the second limiting seat 33, can exert an upward force on the second squeezing roller 36 with the help of the elastic force of the second spring 34, the first squeezing roller 32 and the second squeezing roller 36 can squeeze out the dyeing liquid in the yarn without causing excessive squeezing of the yarn. The yarn moves at a relatively slow speed, and the squeezed dyeing liquid flows downward along the first squeezing roller 32 and the second squeezing roller 36 due to its own weight. The positioning plate 22 in the liquid collection tank 21 can limit the sliding shaft 25. The vertically distributed sliding shaft 25 can be supported by the support block 24 to keep the guide plate 23 in place. Vertically distributed, the first spring 26 located between the positioning plate 22 and the support block 24 can give the guide plate 23 an upward force, causing the elastic rubber strip of the guide plate 23 and the lower end of the rubber coating layer of the second extrusion roller 36 to contact, thus allowing the dyeing liquid to flow down along the guide plate 23 and preventing the dyeing liquid from being reabsorbed by the yarn. The dyeing liquid can be collected in the collection tank 21. If necessary, the switch valve 27 can be opened to allow the dyeing liquid to flow into the waste liquid pool through the drain pipe 28. The yarn after the dyeing liquid has been squeezed out continues to move under the support of multiple support rollers 14. At the same time, air can be drawn in and heated by the hot air blower 15, and the air is discharged through the first air guide shell 16. Hot air is sent into the color-fixing chamber 12, which is fixed by the mounting base 11. The hot air can heat and dry the yarn that is bent and stretched in the color-fixing chamber 12. The support roller 14 can make the yarn in the color-fixing chamber 12 longer, thereby increasing the drying time of the unit yarn. The exhaust fan 17 can create negative pressure in the second air guide shell 18, which can suck away the hot air and the dyeing liquid in the air. The exhaust fan 17 transports the exhaust gas to the yarn dyeing exhaust gas treatment device for treatment. If the device needs to be inspected or maintained, the disassembly plate 13 can be removed to inspect or maintain the internal components of the color-fixing chamber 12.This device uses a second spring 34 to provide an upward squeezing force to the second squeezing roller 36. The second squeezing roller 36 and the first squeezing roller 32 squeeze the yarn to remove the dyeing solution. The first spring 26 also provides an upward squeezing force to the guide plate 23. The guide plate 23, which contacts the second squeezing roller 36, guides the squeezed-out dyeing solution into the collection chamber 21, preventing the yarn from reabsorbing the dyeing solution. Hot air is then discharged through the hot air fan 15 and the first air guide shell 16 to dry the yarn tensioned by multiple support rollers 14. Exhaust gas is recovered through the exhaust fan 17 and the second air guide shell 18. This device can first squeeze out the dyeing solution and then dry the yarn with hot air. It has higher drying efficiency, shorter overall drying time, and a better and more thorough drying effect, ensuring the colorfastness of the yarn.
