Description

Technical Field

[0001] This utility model relates to the field of dyeing equipment technology, and in particular to a dyeing device for colored yarn. Background Technology

[0002] The term "textile" originally referred to the general concepts of spinning and weaving. However, with the continuous development and improvement of textile knowledge and disciplines, especially with the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, it has expanded beyond traditional hand spinning and weaving to include nonwoven fabric technology, modern three-dimensional weaving technology, and modern electrostatic nano-web forming technology for producing clothing, industrial, and decorative textiles. Yarn is an indispensable material in the textile process. When yarn is produced from a spinning machine, it is usually white. For aesthetic purposes, major textile factories currently use dyeing devices to dye the yarn.

[0003] When using the above technology, the following technical problems were found in the existing technology: The dyeing device of the existing technology usually uses a nozzle to spray dye on the passing yarn. At this time, the bottom end of the yarn cannot be effectively dyed. Therefore, this method cannot effectively and evenly immerse the yarn, which easily leads to uneven dyeing and color difference, and there will be dyeing dead corners, thus affecting the dyeing quality. To this end, we designed a dyeing device for colored yarn to provide another technical solution to the above technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A dyeing apparatus for colored yarn includes a dyeing roller, a U-shaped frame slidably connected inside the dyeing roller, pressure rollers rotatably connected to both ends of the bottom of the U-shaped frame, a feed roller rotatably connected to one end of the dyeing roller, a take-up roller rotatably connected to the other end of the dyeing roller, a conveyor roller A rotatably connected to one end of the inner side of the dyeing roller, a guide box fixed to the other end of the inner side of the dyeing roller, a conveyor roller B rotatably connected to one end of the top of the guide box, guide blocks II fixed to both ends of the bottom of the inner side of the dyeing roller, a dyeing box slidably connected to the inner side of the guide blocks II, and a lifting and adjusting mechanism for driving the U-shaped frame and the spun yarn to be immersed in dyeing at the top of the inner side of the dyeing roller.

[0006] As a preferred embodiment of the dyeing device for spun yarn provided by this utility model, the lifting and adjusting mechanism includes a linkage rod, a sliding seat, a second U-shaped frame, and a reverse synchronization component. A T-shaped guide groove is provided at the top of the inner side of the dyeing roller and above the first U-shaped frame. Sliding seats are slidably connected to both sides of the T-shaped guide groove. A linkage rod is rotatably connected to the inner side of the sliding seat. The end of the linkage rod away from the sliding seat is rotatably connected to the first U-shaped frame.

[0007] As a preferred embodiment of the dyeing device for spun yarn provided by this utility model, the opposite synchronization component includes a U-shaped frame, a toothed block, an L-shaped rack, a gear, and a B conveying roller. One end of one of the sliding seats is fixed with a toothed block, and one end of the other sliding seat is fixed with an L-shaped rack. The toothed block and the L-shaped rack are meshed with a gear at their close ends, and the top of the gear is rotatably connected to the dyeing roller.

[0008] In a preferred embodiment of the dyeing device for spun yarn provided by this utility model, a U-shaped frame two is fixed to the top of the inner side of the dyeing roller, and a servo motor is assembled at the bottom of the U-shaped frame two. The output end of the servo motor passes through the U-shaped frame two and is fixed to a gear.

[0009] In a preferred embodiment of the dyeing device for spun yarn provided by this utility model, a guide rail is provided on one side of the inner side of the dyeing roller, and a guide block is fixed on the other side of the inner side of the dyeing roller. The guide rail and the guide block are slidably connected to a U-shaped frame.

[0010] In a preferred embodiment of the dyeing device for spun yarn provided by this utility model, the bottom of the inner side of the guide box is inclined at an angle.

[0011] As a preferred embodiment of the dyeing device for spun yarn provided by this utility model, the other end of the inner side of the dyeing roller is provided with a drying mechanism for fixing the dyed yarn. The drying mechanism includes a fan and a drying box. A rectangular groove is opened at the other end of the inner top of the dyeing roller. A fan is installed on the inner side of the rectangular groove. A drying box is fixed at the bottom end of the rectangular groove. A plurality of heating tubes are installed on the inner side of the drying box.

[0012] In a preferred embodiment of the dyeing device for spun yarn provided by this utility model, a protective sleeve is provided on the outer side of the A conveyor roller, and absorbent cotton is provided on the outer side of the B conveyor roller.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0015] This utility model provides a dyeing device for spun yarn. By starting a servo motor to drive a gear to rotate, the gear drives a toothed block and an L-shaped rack to move away from each other. In turn, the toothed block and the L-shaped rack drive two sliding seats to slide away from each other. The two sliding seats squeeze the linkage rod, and the linkage rod drives a U-shaped frame and a pressure roller to apply pressure downwards along the guide rail and guide block. This causes the pressure roller to bring the spun yarn into contact with the dyeing liquid inside the dyeing box, so that the dyeing liquid inside the dyeing box can immerse the spun yarn and improve the uniformity of the dyeing of the spun yarn.

[0016] The dyed yarn is transported to the surface of the absorbent cotton for adsorption. Then, the heating tube is activated, and the fan is activated simultaneously to blow air onto the heating tube. This facilitates the transfer of heat generated by the heating tube to the surface of the yarn for drying, effectively increasing the positioning effect of the dyed yarn. Attached Figure Description

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Please refer to Figures 1-4 A dyeing apparatus for colored yarn includes a dyeing roller 1, a U-shaped frame 10 slidably connected inside the dyeing roller 1, a guide rail on one side of the inner side of the dyeing roller 1, and a guide block 20 fixed on the other side of the inner side of the dyeing roller 1. The guide rail and the guide block 20 are slidably connected to the U-shaped frame 10. Pressure rollers 11 are rotatably connected to both ends of the bottom of the U-shaped frame 10. A feeding roller 3 is rotatably connected to one end of the dyeing roller 1, and a take-up roller 7 is rotatably connected to the other end of the dyeing roller 1. An A-type roller is rotatably connected to one end of the inner side of the dyeing roller 1. The other end of the inner side of the conveying roller 6 and the dyeing roller 1 is fixed with a guide box 5. The bottom of the inner side of the guide box 5 is at an inclined angle. The top end of the guide box 5 is rotatably connected to the B conveying roller 18. The outer side of the A conveying roller 6 is provided with a protective sleeve. The outer side of the B conveying roller 18 is provided with absorbent cotton. Both ends of the bottom of the inner side of the dyeing roller 1 are fixed with guide blocks 2. The inner side of the guide blocks 2 is slidably connected to the dyeing box 4. The top of the inner side of the dyeing roller 1 is provided with a lifting adjustment mechanism for driving the U-shaped frame 10 and the yarn to be immersed in dyeing.

[0028] In use, the spinning roller is placed on the surface of the feeding roller 3, and one end of the spinning yarn passes through the A conveying roller 6, the pressure roller 11 and the B conveying roller 18 to wind and take up the yarn with the take-up roller 7. Then, the dyeing liquid is injected into the inside of the dyeing box 4. Then, the lifting and adjusting mechanism drives the U-shaped frame 10 to slide down along the guide block 20 and the guide rail. The U-shaped frame 10 drives the pressure roller 11 and the spinning yarn to move towards the inside of the dyeing box 4. Then, the dyeing liquid inside the dyeing box 4 impregnates the spinning yarn. This method helps to improve the dyeing uniformity of the spinning yarn. Then, the absorbent cotton on the surface of the B conveying roller 18 absorbs the dyeing liquid on the surface of the spinning yarn. The liquid absorbed by the absorbent cotton falls into the inside of the guide box 5. The guide box 5 effectively guides the liquid into the inside of the dyeing box 4, and then circulates in sequence to avoid waste and pollution of the dyeing liquid.

[0029] The lifting and adjusting mechanism includes a linkage rod 12, a sliding seat 13, a U-shaped frame 14, and a reverse synchronization component. A T-shaped guide groove is provided at the top of the inner side of the dyeing roller 1 and above the U-shaped frame 10. The sliding seats 13 are slidably connected to both sides of the T-shaped guide groove. The linkage rod 12 is rotatably connected to the inner side of the sliding seat 13. The end of the linkage rod 12 away from the sliding seat 13 is rotatably connected to the U-shaped frame 10.

[0030] The opposite synchronization component includes a U-shaped frame 14, a toothed block 15, an L-shaped rack 16, a gear 17, and a B conveyor roller 18. One end of a sliding seat 13 is fixed with a toothed block 15, and one end of another sliding seat 13 is fixed with an L-shaped rack 16. The gear 17 is meshed with the ends of the toothed block 15 and the L-shaped rack 16 that are close to each other. The top end of the gear 17 is rotatably connected to the dyeing roller 1. The top end of the inner side of the dyeing roller 1 is fixed with a U-shaped frame 14. The bottom end of the U-shaped frame 14 is equipped with a servo motor 19. The output end of the servo motor 19 passes through the U-shaped frame 14 and is fixed with the gear 17.

[0031] Specifically, when it is necessary to drive the spinning yarn for dyeing, the servo motor 19 drives the gear 17 to rotate, and the gear 17 drives the tooth block 15 and the L-shaped rack 16 to move away from each other. Then, the tooth block 15 and the L-shaped rack 16 drive the two sliding seats 13 to slide away from each other. The two sliding seats 13 squeeze the linkage rod 12, and the linkage rod 12 drives the U-shaped frame 10 and the pressure roller 11 to apply pressure downward along the guide rail and the guide block 20, so that the pressure roller 11 drives the spinning yarn to contact the dyeing liquid inside the dyeing box 4, so that the dyeing liquid inside the dyeing box 4 can immerse the spinning yarn.

[0032] The other end of the inner side of the dyeing roller 1 is provided with a drying mechanism for fixing the dyed yarn. The drying mechanism includes a fan 8 and a drying box 9. A rectangular groove is opened at the other end of the inner top of the dyeing roller 1. The fan 8 is installed inside the rectangular groove. The drying box 9 is fixed at the bottom of the rectangular groove. Several heating tubes are installed inside the drying box 9.

[0033] Furthermore, the dyed yarn is transported to the surface of the absorbent cotton for adsorption, and then the heating tube is activated, and the fan 8 is activated simultaneously to blow air to the heating tube, so that the heat generated by the heating tube can be transferred to the surface of the yarn for drying, effectively increasing the positioning effect of the yarn dyeing.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
