Description

Technical Field

[0001] This utility model relates to the field of knitted fabric dyeing, and in particular to a knitted fabric dyeing device. Background Technology

[0002] Knitted fabrics are loved for their comfort, elasticity, breathability and softness. However, knitting mainly involves interlocking loops, and its unstable structure makes it prone to unraveling, deformation, poor wear resistance and snagging. Therefore, in the dyeing of knitted fabrics, manufacturers often use airflow dyeing equipment with low tension and low friction.

[0003] The air overflow dyeing equipment moves the fabric through airflow and nozzles. The fabric is dyed by the overflow dye liquor and the spray of dye particles from the airflow, which reduces friction and achieves uniform dyeing. After dyeing, the fabric is exported and stored through a swing structure.

[0004] The swing structure requires a relatively high height to unload and store the fabric. However, common swing structures are fixed to the top of the dyeing vat by a structural frame. The dyeing vat of the air overflow dyeing equipment is a large piece of equipment, and a fixed structural frame is very inconvenient for unloading the fabric after dyeing. Therefore, a knitted fabric dyeing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a knitted fabric dyeing device, which aims to improve the problem that the structural frame of the swing structure of the existing knitted fabric dyeing device cannot move up and down.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A knitted fabric dyeing device includes a dyeing cylinder, a support frame fixedly connected to the top of the dyeing cylinder, a housing fixedly connected to the top of the support frame, a fixed shaft fixedly connected inside the housing, a gear rotatably connected to the outside of the fixed shaft, a telescopic cylinder fixedly connected inside the housing, a rack fixedly connected to the output end of the telescopic cylinder, the rack meshing with the gear, a structural frame fixedly connected to the top of the gear, and a swing mechanism installed at the end of the structural frame.

The outer side of the top block is slidably connected to the inside of the fixed shell. A scraper is fixedly connected to the end of the top block.

[0016] As a further description of the above technical solution:

[0017] A heating wire is fixedly connected to the inner wall of the mixing tank.

[0018] As a further description of the above technical solution:

[0019] A dye tank is fixed to the top of the mixing tank. A second motor is fixedly connected to the top of the dye tank. A spiral shaft is fixedly connected to the output end of the second motor. A connecting frame is fixedly connected to the middle of the spiral shaft. Baffles are fixedly connected to both sides of the connecting frame.

[0020] As a further description of the above technical solution:

[0021] A feed pipe is fixedly connected to the bottom of the dye tank, and the spiral shaft is rotatably connected to the inner side of the feed pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the telescopic cylinder drives the fixed rack to move back and forth, and the meshing gear rotates on the fixed shaft, causing the structure frame of the swing structure fixed on the top of the gear to rotate, thereby achieving the purpose of adjusting the structure frame of the swing structure up and down, so that the dyed fabric can easily pass through the swing mechanism that falls to the lowest point, and then the swing mechanism is adjusted to rise to the highest point for swing storage.

[0024] 2. In this utility model, the dye inside the mixing tank is squeezed by the spring telescopic structure fixed on both sides of the mixing rod, causing the scraper to stick tightly to the inner wall. When the motor is working, the dye on the inner wall is scraped off, and at the same time, the internal heating wire heats up, so that the dye is heated and stirred evenly, reducing dye loss.

[0025] 3.

A support frame 21 is fixedly connected to the top of the dyeing cylinder 1. The support frame 21 supports the lifting structure of the structural frame 20. A housing 15 is fixedly connected to the top of the support frame 21. The housing 15 is used to fix and protect the internal structure from environmental influences. A fixed shaft 18 is fixedly connected inside the housing 15. A gear 17 is rotatably connected to the outside of the fixed shaft 18. The fixed shaft 18 causes the gear 17 to rotate around the shaft. A telescopic cylinder 19 is fixedly connected inside the housing 15. A rack 16 is fixedly connected to the output end of the telescopic cylinder 19. When the telescopic cylinder 19 telescopically moves, it drives the fixed shaft 18 to rotate. The rack 16 fixed at the output end moves back and forth, and the rack 16 meshes with the gear 17. Driven by the telescopic cylinder 19, the telescopic rack 16 drives the meshing gear 17 to rotate. A structural frame 20 is fixedly connected to the top of the gear 17. When the rack 16 drives the gear 17 to rotate at a certain angle, the structural frame 20 fixed to the top of the gear 17 rotates at the same time at a certain angle, so that the structural frame 20 can be adjusted up and down. A swing mechanism 22 is installed at the end of the structural frame 20, so that the swing mechanism 22 can be adjusted up and down, so that the dyed fabric can easily pass through the swing mechanism 22 that falls to the lowest point, and then the swing mechanism 22 is adjusted to rise to the highest point for swinging and storage.

[0035] Reference Figure 2 and Figure 5 A conveying pipe 14 is fixedly connected to the top of the dyeing tank 1. A water pump 23 is fixedly connected to the end of the conveying pipe 14. A stirring tank 2 is fixedly connected to the end of the conveying pipe 14. The water pump 23 is used to draw the dye liquor that has been stirred and processed in the stirring tank 2 and transport it to the dyeing tank 1 through the conveying pipe 14. A motor 4 is fixedly connected inside the stirring tank 2. A stirring rod 5 is fixedly connected to the output end of the motor 4. When the motor 4 starts, it drives the stirring rod 5 fixed to the output end to rotate. Fixed housings 24 are fixedly connected to both sides of the stirring rod 5. Springs 6 are fixedly connected inside the fixed housings 24. To fix the spring 6 and reduce the influence of the dye liquor on the spring 6, a top block 25 is fixedly connected to the end of the spring 6. The outer side of the top block 25 is slidably connected to the inside of the fixed shell 24. A scraper 7 is fixedly connected to the end of the top block 25. The scraper 7 fixed on the top block 25 fits tightly against the inside of the stirring tank 2 under the action of the spring 6. Driven by the motor 4, the dyeing dye is stirred. The scraper 7 scrapes the dye off the inner wall to achieve the purpose of uniform stirring. A heating wire 3 is fixedly connected to the inner wall of the stirring tank 2. While stirring, the dye is heated by the heating wire 3, which can achieve uniform heating of the dye.

[0036] Reference Figure 4A dye tank 9 is fixedly connected to the top of the mixing tank 2. Dye powder is dropped in a timed and quantitative manner, which can reduce working time and more accurately prepare suitable dyes. A motor 10 is fixedly connected to the top of the dye tank 9. A spiral shaft 11 is fixedly connected to the output end of the motor 10. When the motor 10 starts, it drives the spiral shaft 11 fixed at the output end to rotate. A connecting frame 12 is fixedly connected to the middle of the spiral shaft 11. The fixed connecting frame 12 rotates together with the spiral shaft 11. Baffles 13 are fixedly connected to both sides of the connecting frame 12. When the baffles 13 rotate, they can scrape the dye powder and squeeze the powder towards the spiral shaft 11. A feed pipe 8 is fixedly connected to the bottom of the dye tank 9. The spiral shaft 11 is rotatably connected to the inside of the feed pipe 8. Driven by the motor 10, the spiral shaft 11 drives the dye powder to rotate and fall evenly into the mixing tank 2 through the feed pipe for mixing.

[0037] Working principle: First, start motor 10 to drive the spiral shaft 11 to rotate, causing the baffle 13 to rotate and press the dye powder tightly against the spiral shaft 11. At the same time, the rotating spiral shaft 11 drives the dye powder to fall evenly into the interior of the mixing tank 2 through the feed pipe 8. Then, start motor 4 to drive the stirring rod 5 to rotate. At the same time, the scraper 7 scrapes off the dye on the inner wall of the mixing tank 2 to evenly stir the dye liquor. While stirring the dye, the heating wire 3 evenly heats the dye. The heated and evenly stirred dye liquor is transported to the dyeing tank 1 through the conveying pipe 14 by the water pump 23 for overflow to dye the fabric.

[0038] When the fabric is dyed in the dyeing tank 1, the telescopic cylinder 19 is activated to retract the rack 16 fixed at the output end, which drives the meshing gear 17 to rotate, causing the structural frame 20 fixed at the top of the gear 17 to rotate and fall to the lowest point, passing the dyed fabric through the swing mechanism 22. Then, the telescopic cylinder 19 is activated to extend the rack 16 fixed at the output end, causing the structural frame 20 to rotate and rise to the highest point for swing storage.
