Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a device for uniform dyeing of high-elastic colored yarn packages. Background Technology

[0002] High-elasticity colored yarn is a tubular yarn that has undergone dyeing treatment and possesses high elasticity. It is made from thermoplastic chemical fiber filaments through a false twisting process, with each monofilament in the yarn arranged in a spiral shape. It adopts an environmentally friendly dyeing process, achieving a color fastness of level 4 or higher, ensuring that it is not easy to fade after washing. It meets the requirements of medical accessories, socks, and other applications with high color fastness requirements. The yarn is wound into a tubular shape, which facilitates continuous processing by automated equipment, improves production efficiency, and reduces yarn splices, thereby reducing the breakage rate.

[0003] A search revealed that Chinese Patent CN217419013U discloses a uniform dyeing device for high-elasticity yarn packages. This device addresses the problems of existing common yarn package dyeing machines, where dye molecules come into contact with and exchange with fibers at different points along with the liquid flow. These problems result in uneven and inconsistent flow rates and intensities, difficulty in controlling temperature differences between different layers of dye liquor within the dye bath, and inconsistent immersion times. Consequently, these machines produce large color differences between inner and outer layers of the same yarn package, significant color differences between different yarn packages within the same dye bath, and long dyeing times with low efficiency. Therefore, this device offers more uniform yarn package dyeing, higher dyeing efficiency, a more stable structure, and safer operation.

[0004] The above-mentioned yarn package dyeing improves dyeing uniformity through the circulation of liquid. However, in the prior art, the yarn package is stationary during the dyeing process, which easily leads to uneven dyeing of the yarn package due to the accumulation of yarn in the package, the magnitude of the dye flow rate, and the uneven distribution of dye inside the dyeing barrel. This results in a reduction in the dyeing quality of the yarn package. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform dyeing device for high-elasticity colored yarn packages.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a uniform dyeing device for high-elastic colored yarn, including a dyeing barrel, a barrel cover hinged to the upper surface of the dyeing barrel, a drain pipe connected through one side of the dyeing barrel, a liquid-blocking cap threaded to one end of the drain pipe, a protective shell fixedly connected to the lower surface of the dyeing barrel, a plurality of heat dissipation grooves opened on the lower surface of the protective shell, and a rotating component provided on the lower surface of the dyeing barrel. The rotating assembly includes a sealing turntable, which is rotatably connected to the lower surface of the dyeing barrel, and a toothed ring is fixedly connected to the outside of the sealing turntable.

[0007] As a further description of the above technical solution: The sealing turntable is disposed inside the protective shell, and a first variable speed motor is fixedly installed inside the protective shell. The output end of the first variable speed motor is fixedly connected to a first gear.

[0008] As a further description of the above technical solution: The first gear and the gear ring are meshed together. A second variable speed motor is fixedly installed on the lower surface of the sealing turntable, and a second gear is fixedly connected to the output end of the second variable speed motor.

[0009] As a further description of the above technical solution: The lower surface of the sealing turntable is rotatably connected to multiple driven gears, which are meshed with the second gear. The upper surface of the driven gears is fixedly connected to a limiting column via a rotating shaft, and a mounting column is provided on the outside of the limiting column.

[0010] As a further description of the above technical solution: The dyeing tank is connected to two sides by a double-ended pipe, and a conveying pipe is connected to the middle of the double-ended pipe. Both ends of the double-ended pipe are connected to a U-shaped pipe, and multiple spray heads are connected to the inner wall of the U-shaped pipe.

[0011] As a further description of the above technical solution: The mounting post has an internal mounting assembly, which includes a slot at one end of the mounting post. The mounting post has a threaded connection to a limit ring on its exterior, and multiple recesses are formed on its exterior. Sealing limit rings are fixedly connected to the inner walls of the recesses.

[0012] As a further description of the above technical solution: A spring is fixedly connected inside the recessed hole. The spring is coated with epoxy paint. A blocking plate is fixedly connected to one end of the spring. A pushing block is fixedly connected to one side of the blocking plate. A silicone pad is provided on one side of the pushing block.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the setting of the rotating component, utilizes the rotation of the sealed turntable to facilitate the revolution of multiple yarn packages installed on the mounting columns. The limiting square column facilitates the revolution of the mounting columns while simultaneously generating their own rotation. During the rotation of the mounting columns, the yarn packages pass through the interior of the U-shaped tubes on both sides in sequence and are sprayed with dye by the spray head. Furthermore, the cyclical rotation of the mounting columns facilitates the improvement of the uniformity of yarn package dyeing, thereby improving the dyeing quality of the yarn packages.

[0014] 2. This utility model, through the setting of the installation components, utilizes the square shape of the limiting column to facilitate the limiting of the installation column by the four corners of the square when it is inserted into the slot, so that the installation column can rotate together with the limiting column. The pusher block applies a large outward pushing force, and the friction of the silicone pad, under the limiting effect of the limiting ring, makes it easy for the yarn package to be firmly installed on the outside of the installation column and rotate together with the installation column.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As attached Figure 1-7As shown, one embodiment of this utility model is provided: a uniform dyeing device for high-elasticity colored yarn, including a dyeing barrel 1, a barrel cover 2 hinged to the upper surface of the dyeing barrel 1, a drain pipe 3 connected through one side of the dyeing barrel 1, a liquid blocking cover 4 threaded to one end of the drain pipe 3 to facilitate the discharge of dye liquor, a protective shell 5 fixedly connected to the lower surface of the dyeing barrel 1, a plurality of heat dissipation grooves 6 opened on the lower surface of the protective shell 5 for heat dissipation of the motor, and a rotating component provided on the lower surface of the dyeing barrel 1. The rotating assembly includes a sealing turntable 7, which is rotatably connected to the lower surface of the dyeing barrel 1. A gear ring 8 is fixedly connected to the outside of the sealing turntable 7 to facilitate connection to the first gear 10.

[0019] As attached Figure 3 As shown, the sealing turntable 7 is disposed inside the protective shell 5. A first variable speed motor 9 is fixedly installed inside the protective shell 5. A first gear 10 is fixedly connected to the output end of the first variable speed motor 9. The first gear 10 and the gear ring 8 are meshed, which facilitates the rotation of the sealing turntable 7 and provides a seal during rotation. A second variable speed motor 11 is fixedly installed on the lower surface of the sealing turntable 7. A second gear 12 is fixedly connected to the output end of the second variable speed motor 11. Multiple driven gears 13 are rotatably connected to the lower surface of the sealing turntable 7. The multiple driven gears 13 and the second gear 12 are meshed, which facilitates the rotation of the limiting column 14.

[0020] As attached Figure 4 As shown, the upper surface of the driven gear 13 is fixedly connected to a limiting square post 14 via a rotating shaft. The rotating shaft is rotatably connected inside the sealing turntable 7. It is sealed when rotating, and the square shape facilitates the limiting of the mounting post 15 through the slot 16.

[0021] As attached Figure 6 As shown, the limiting column 14 has an installation column 15 on its outside for installing the yarn package. The dyeing barrel 1 has a double-ended pipe 24 that runs through both sides to facilitate the double-ended delivery of dye. The middle of the double-ended pipe 24 is connected to a delivery pipe 25. Both ends of the double-ended pipe 24 are connected to U-shaped pipes 26 to facilitate the passage of the installation column 15 and to ensure that both sides of the yarn package are sprayed with dye. The inner wall of the U-shaped pipe 26 is connected to multiple spray nozzles 27. The installation column 15 has an installation component inside, which includes a slot 16 that matches the height and shape of the limiting column 14. The slot 16 is opened at one end of the installation column 15. The installation column 15 has a threaded connection to a limiting ring 17 on its outside to block and limit the bottom of the yarn package. The installation column 15 has multiple recesses 18 on its outside. The inner wall of the recesses 18 is fixedly connected to a sealing limiting ring 19 to reduce moisture erosion and limit the movement of the blocking plate 21.

[0022] As attached Figure 7As shown, a spring 20 is fixedly connected inside the recess 18, which pushes the baffle plate 21 and the push block 22. The outside of the spring 20 is coated with epoxy paint, which protects the spring 20 from moisture. One end of the spring 20 is fixedly connected to the baffle plate 21, which prevents the push block 22 from moving and also prevents moisture from corroding the spring 20. The push block 22 is fixedly connected to one side of the baffle plate 21, which makes it easy to push and tighten it against the inner wall of the yarn package. A silicone pad 23 is provided on one side of the push block 22 to increase friction and improve the tightness of the yarn package installation.

[0023] Working principle: When in use, first connect the conveying pipe 25 to the dyeing liquid tank pipe of the external conveying dyeing liquid. When taking the installation column 15 out of the dyeing barrel 1, first rotate the limiting ring 17 to remove the limiting ring 17 from one end of the installation column 15. Then, put multiple yarn packages one by one longitudinally on the outside of the installation column 15. After the yarn packages are installed, the inner wall will squeeze the multiple silicone pads 23 on the outside. The silicone pads 23 generate friction on the inner wall of the yarn packages and are pressed against the push block 22. The push block 22 is pressed against the spring 20 through the baffle plate 21. Then the spring 20 is pressed and rebounds. The multi-faceted push block 22 applies a pushing force outward to press the inner wall of the yarn packages tightly, so that the yarn packages are installed securely. Then, screw the limiting ring 17 back to the outside of the installation column 15 to limit the bottom of the yarn packages. Insert one end of the mounting post 15 into the outside of the limiting post 14 using the slot 16, so that the mounting post 15 is limited by the limiting post 14. Then close the lid 2. Use the controller to start the first speed motor 9 and the second speed motor 11. When the output end of the first speed motor 9 drives the first gear 10 to rotate, the first gear 10 will mesh with the gear ring 8, driving the gear ring 8 to rotate, which in turn drives the sealing turntable 7 to rotate. The sealing turntable 7 indirectly drives the multiple limiting posts 14 to revolve. When the output end of the second speed motor 11 drives the second gear 12 to rotate, the second gear 12 meshes with the driven gear 13. The combined action drives multiple driven gears 13 to rotate, which in turn drives the limiting column 14 via the rotating shaft, thereby causing the mounting column 15 to rotate. This causes multiple yarn packages to rotate while revolving around the central axis, and then the dye is transported to the inside of the conveying pipe 25. After being transmitted through the double-ended pipe 24 and the U-shaped pipe 26, the dye is transported to the inside of the spray head 27 and sprayed out. When the yarn packages revolve and rotate through the inside of the U-shaped pipe 26, they will be sprayed with dye by the spray head 27. When a large amount of dye accumulates inside the dyeing tank 1 and the liquid level rises, the uniformity of dyeing is further improved during the rotation of the yarn packages.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
