[0025] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model: a fabric tensioning device during the dyeing process of denim, including a bottom plate 1. A dyeing tank 3 is fixedly connected to the upper part of the bottom plate 1. A first connecting frame 23 is fixedly connected to the upper left side of the dyeing tank 3. A third motor 19 is arranged outside the first connecting frame 23. A belt drive assembly 20 is fixed to the output end of the third motor 19. A feeding roller 21 is installed inside the first connecting frame 23. The feeding roller 21 is fixedly connected to the output end of the third motor 19. A second connecting frame 24 is fixedly connected to the upper right side of the dyeing tank 3. A discharging roller 22 is installed inside the second connecting frame 24. The other end of the belt drive assembly 20 is fixedly connected to the outside of the second connecting frame 24. A fixing frame 5 is fixedly connected to the upper part of the dyeing tank 3. An installation block 6 is fixedly connected to the upper part of the fixing frame 5. A first motor 8 is arranged outside the installation block 6. A gear 9 is fixedly connected to the output end of the first motor 8. A rack plate 10 is meshed and connected to the outside of the gear 9. A cross plate 11 is fixedly connected to the bottom of the rack plate 10. A tensioning roller 13 is installed inside the cross plate 11. An anti-sedimentation component 16 is arranged at the rear side outside the dyeing tank 3. The anti-sedimentation component 16 can prevent the pigment from precipitating inside the dyeing tank 3. Installation holes 2 are respectively opened at the four corners inside the bottom plate 1. An L-shaped plate 7 is fixedly connected to the outside of the installation block 6. The first motor 8 is fixedly connected inside the L-shaped plate 7. Telescopic rods 14 are fixedly connected to both sides inside the fixing frame 5. The tops of the two telescopic rods 14 are fixedly connected to the upper part of the cross plate 11. Pool inner rollers 17 are installed on both sides inside the dyeing tank 3. Discharge ports 4 are installed on the front side outside the dyeing tank 3. Valves are installed outside the discharge ports 4. A fixing ring 18 is fixedly connected to the outside of the first connecting frame 23. The third motor 19 is fixedly connected inside the fixing ring 18.

[0027] During the dyeing process of denim, when it is necessary to adjust the tension of the denim, the first motor 8 is started. After the first motor 8 is started, it drives the gear 9 with a fixed output end to start rotating. The rotation of the gear 9 further drives the externally meshed rack plate 10 to move downward. As the rack plate 10 moves downward, the cross plate 11 fixed to its bottom also moves downward accordingly. During the movement of the cross plate 11, the mounting bracket 12 connected to its lower part is also driven to move downward. The movement of the mounting bracket 12 drives the tension roller 13 installed inside to move downward. When the tension roller 13 moves downward, it applies a downward pulling force to the denim in the dyeing tank, thereby increasing the tension of the denim. This enables the denim to maintain a flat and unfolded state in the dyeing tank 3, avoiding wrinkles and overlapping phenomena. Through such adjustment, not only can the dyeing process be made more uniform, reducing color difference and spots, but also the quality of the dyed denim fabric can be significantly improved.

[0028] Refer to Figure 2 and Figure 5 As shown in and

[0028] , the anti-precipitation component 16 includes a second motor 1601. The second motor 1601 is arranged at the outer rear side of the dyeing tank 3. The output ends of the second motor 1601 are fixedly connected with first transmission wheels 1602. Both sides inside the dyeing tank 3 are fixedly connected with rotating rods 1605. Second transmission wheels 1604 are fixedly connected to the outer parts of the two rotating rods 1605. The two first transmission wheels 1602 are connected to the two second transmission wheels 1604 through two transmission belts 1603. Stirring rods 1606 are fixedly connected to the outer peripheries of the two rotating rods 1605. An installation ring 15 is fixedly connected to the outer rear side of the dyeing tank 3. The second motor 1601 is fixedly connected inside the installation ring 15.

[0029] When pouring the dyeing pigment into the interior of the dyeing tank 3, the second motor 1601 is started, which drives the two first transmission wheels 1602 fixed to the output end to start rotating. As the first transmission wheels 1602 rotate, the two transmission belts 1603 connected thereto will also operate synchronously, thereby driving the two second transmission wheels 1604 to rotate. The rotation of the second transmission wheels 1604 further drives the two rotating rods 1605 fixed inside to rotate. When these two rotating rods 1605 rotate, they drive the stirring rods 1606 fixed around the outside to rotate. The rotation of the stirring rods 1606 can fully stir the pigment inside the dyeing tank 3. In this way, during the process of pouring the pigment into the interior of the dyeing tank 3, it can be ensured that the pigment is evenly stirred and distributed. The stirring process can not only prevent the pigment from depositing at the bottom or on the walls of the tank, but also ensure the uniformity of the entire dye solution. The design of the stirring rods 1606 enables them to cover the entire interior area of the dyeing tank 3, so that the pigment can be evenly distributed throughout the tank. It is possible to perform the stirring operation in real time during the dyeing process, avoiding the unevenness and low efficiency of manual stirring. In addition, through this mechanized stirring method, the workload of manual operation can be greatly reduced, the production efficiency can be improved, and the stirring ensures the stability and consistency of each batch of dyeing operations. The finally produced denim not only has uniform color but also higher quality.

[0030] Working principle: When it is necessary to adjust the tension of the denim, by starting the first motor 8, the first motor 8 drives the gear 9 with a fixed output end to rotate. The rotation of the gear 9 drives the externally meshed rack plate 10 to move downward. The downward movement of the rack plate 10 drives the bottom-fixed horizontal plate 11 to move downward. When the horizontal plate 11 moves, it drives the lower-fixed mounting bracket 12 to move. The movement of the mounting bracket 12 drives the tension roller 13 installed inside to move downward. When the tension roller 13 moves, it drives the denim in the tank to move downward to increase the tension of the denim, achieving the convenience of adjusting the tension of the denim during the dyeing process of the denim, ensuring that the denim can be smoothly unfolded in the dyeing tank 3, avoiding wrinkles and overlaps, making the dyeing process more uniform, reducing color differences and spots, and improving the quality of the dyed denim. When pouring the dyeing pigment into the inside of the dyeing tank 3, by starting the second motor 1601, the second motor 1601 drives the two first transmission wheels 1602 with fixed output ends to rotate. The rotation of the two first transmission wheels 1602 drives the two second transmission wheels 1604 to rotate through the two transmission belts 1603. The rotation of the two second transmission wheels 1604 drives the two rotating rods 1605 fixed inside to rotate. The rotation of the two rotating rods 1605 drives the stirring rods 1606 fixed around the outside to rotate. Just stir the pigment inside the dyeing tank 3 through the rotation of the stirring rods 1606, achieving the convenience of stirring the pigment inside the dyeing tank 3 when pouring the pigment into the inside of the dyeing tank 3. Stirring can make the pigment evenly distributed in the dyeing tank 3, prevent the pigment from depositing at the bottom or on the wall of the tank, and ensure the uniformity of the dye solution.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
