AI Technical Summary
Existing aramid fabric dyeing equipment requires workers to immerse their hands in dye solution when installing the fabric, which is harmful to health and may stain clothing. In addition, the dyeing is uneven and the dye utilization rate is low.
The design incorporates pressing, tensioning, scraping, and filtering mechanisms. A motor-driven screw pulley presses down the fabric, automatically adjusting the tension, scraping off excess dye, and filtering back the dye. This prevents workers from coming into contact with the dye liquor, ensuring uniform dyeing and dye recycling.
Protect workers' health, improve dyeing quality and dye utilization, reduce environmental pollution, and enhance dyeing uniformity and efficiency.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This aramid fabric dyeing device, by setting up a pressing mechanism, uses a motor-driven screw to cause a movable block to drive a pressure roller to press down the fabric. When installing the fabric, the worker's hands do not need to be immersed in the dye solution, thus ensuring the worker's health. At the same time, the tensioning mechanism can automatically adjust the fabric tension to avoid the fabric being too loose or too tight, ensuring dyeing uniformity and significantly improving the dyeing quality.

[0024] 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.
[0025] like Figure 1-4 As shown, this utility model provides a technical solution:
[0026] A dyeing apparatus for aramid fabric includes a dye tank 1. A back frame 2 is vertically arranged at the top back of the dye tank 1. Two guide rollers 3 are arranged side by side on the lower left side of the front of the back frame 2. A pressing mechanism is arranged on the front of the back frame 2, near the upper ends of the two guide rollers 3. The pressing mechanism includes a guide groove 5. The guide groove 5 is opened on the left side of the front of the back frame 2. A lead screw 6 is vertically arranged inside the guide groove 5. A motor 7 is arranged at the top left side of the back frame 2. The output shaft of the motor 7 is fixedly connected to the lead screw 6. A movable block 8 is threadedly connected to the outside of the lead screw 6. A hanging device is vertically arranged on the outside of the movable block 8. A pressure roller 10 is horizontally arranged at the bottom front of the frame 9 and a guide roller 4 is horizontally arranged below the center of the front of the back frame 2. A tensioning mechanism is arranged between the upper end of the guide roller 4 and the right guide roller 3. The tensioning mechanism includes a movable groove 11. The movable groove 11 is opened in the center of the front of the back frame 2. A movable block 12 is movably arranged in the center of the inner side of the movable groove 11. The upper and lower ends of the movable block 12 are movably connected to the movable groove 11 by springs 13. A hanger 14 is vertically arranged on the outer side of the movable block 12. A tensioning roller 15 is horizontally arranged below the front of the hanger 14.
[0027] In this embodiment, by setting up a pressing mechanism, the motor 7 drives the lead screw 6 to make the movable block drive the pressure roller 10 to press down the fabric. When installing the fabric, the worker's hands do not need to be immersed in the dye solution, which protects the worker's health. At the same time, the tensioning mechanism can automatically adjust the fabric tension to avoid the fabric being too loose or too tight, ensuring dyeing uniformity and significantly improving dyeing quality.
[0028] like Figure 3 and Figure 4 As shown, a scraping mechanism is provided on the right side of the front of the back frame 2. The scraping mechanism includes a horizontal plate 16. The horizontal plate 16 is horizontally arranged at the upper right side of the front of the back frame 2. An electric push rod 17 is fixedly installed at the top center of the horizontal plate 16. A triangular scraper 18 is provided at the output shaft end of the electric push rod 17. A triangular scraper 19 is horizontally arranged at the lower right side of the front of the back frame 2. The triangular scraper 19 and the triangular scraper 18 are angularly offset. A filtration mechanism is provided in the middle of the front of the dye pool 1. The filtration mechanism includes a filter pool 20. The filter pool 20 is connected to the middle of the front of the dye pool 1. Several placement slots 21 connected to the inside of the filter pool 20 are arranged vertically and side by side at the upper end of the filter pool 20. A filter plate 22 is vertically arranged between the placement slot 21 and the filter pool 20. A handle 23 is fixedly installed at the top center of the filter plate 22. A drain pipe 24 is connected to the lower front of the filter pool 20.
[0029] In this embodiment, the triangular scraper 19 and triangular scraper 2 18 in the scraping mechanism are set at different angles. During the fabric conveying process, they can effectively scrape off excess dye and avoid excessive clamping that could damage the fabric. The filtration mechanism filters the returned dye, which improves the quality of dye recycling and reduces environmental pollution.
[0030] Working principle: When dyeing aramid fabric, the fabric is passed sequentially through the upper ends of two guide rollers 3, then through the lower end of tension roller 15, then through the upper end of guide roller 4, and finally exits between triangular scrapers 18 and 19, winding onto the outer take-up roller. Then, motor 7 is started, driving screw 6 to rotate. Screw 6 drives movable block 8 to descend. Movable block 8, through hanger 9, drives pressure roller 10 to press down the fabric between the two guide rollers 3, immersing the fabric in the dye bath 1 below, where it is dyed. This eliminates the need for workers to immerse their hands in the dye bath when installing the fabric. The fabric will also experience some slack during transport. When the fabric relaxes, spring 13 pushes movable block 12 down, causing tension roller 15 to move downward, increasing the tension on the fabric. During fabric conveying, electric actuator 17 is activated, controlling triangular scraper 18 to descend. This creates a staggered tension between triangular scraper 18 and triangular scraper 19, with the upper surface of the fabric moving against the lower end of triangular scraper 18 and the lower surface moving against the upper surface of triangular scraper 19. This avoids over-clamping and damage to the fabric, while also scraping out excess dye from the fabric. The scraped-out dye flows back down and enters the filter tank 20, where it is filtered through several filter plates 22.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
