Description

Technical Field

[0001] The utility model relates to the technical field of textile cloth processing, in particular to a textile cloth dyeing device. Background Art

[0002] Exhaust dyeing is the most commonly used dyeing method for dyeing cotton with reactive dyes. Exhaust dyeing can be divided into three dyeing methods: one-bath one-step method, one-bath two-step method, and two-bath method. Specifically, the tied fabric is placed in the prepared dye solution and soaked for a certain period of time. After dyeing, it is rinsed with clean water, untied, and ironed.

[0003] Under existing conditions, a mechanical structure is used to replace the traditional manual operation method. For example, a textile fabric dyeing device disclosed in the announcement number CN210506793U can ensure the stable movement of the first support rod while the lifting cylinder drives the lifting rod to lift and lower. At the same time, a rotatable stirring member is provided to stir the dyeing liquid. However, the textile fabric itself has a long structure and a light and soft texture. It is very easy to wrinkle and overlap in the dyeing liquid, resulting in differences in the degree of occurrence of the dyeing liquid in various parts. The stirring member with a fixed structure can only drive the stirring blade to stir in a single direction, and it is difficult to fully contact the dyeing liquid in the dyeing equipment, especially the solute is very easy to precipitate at the bottom position, and it is difficult to achieve uniform dyeing processing of the textile fabric.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 3 A textile fabric dyeing device comprises a chassis 1 with an upper chamber 101 and a lower chamber 102, a three-way pipe 103 for connecting the upper chamber 101 and the lower chamber 102 is opened at the middle end of the chassis 1, and one-way valves are provided at the middle end opening of the three-way pipe 103 extending outside the chassis 1 and the upper end opening connecting the upper chamber 101, the one-way valve at the middle end opening allows the air outside the chassis 1 to enter the three-way pipe 103 in one direction when the booster piston 12 moves downward, and the one-way valve at the upper end opening allows the air in the three-way pipe 103 to enter the upper chamber 101 in one direction when the booster piston 12 moves upward.

[0025] Steering rollers 2 for pulling the textile cloth are symmetrically arranged on both sides of the upper chamber 101, and a long guide hole 3 is opened in the middle of the upper chamber 101. The chassis 1 is provided with a driving cylinder 4 and a lifting frame 5 driven by the driving cylinder 4 to lift and lower through the long guide hole 3, and a booster roller 6 for applying downward pressure to the textile cloth is arranged on the lifting frame 5. By staggering the steering rollers 2 and the booster rollers 6, the textile cloth can be located in the upper chamber 101 in an inverted Ω shape, achieving large-area contact with the dyeing liquid, and at the same time achieving tension support for the textile cloth, so that the textile cloth located in the dyeing liquid always maintains a smooth open state.

[0026] The chassis 1 is provided with a driving motor 7 and a driving shaft 8 driven to rotate by the driving motor 7 through the lower chamber 102 and the upper chamber 101, and the chassis 1 is provided with a driving mechanism for accelerating the movement of the dyeing liquid through the driving shaft 8. For details, refer to the attached manual. Figure 2 , further explained:

[0027] On the one hand, the driving mechanism includes a traction roller 9 fixedly mounted on the lower section of the driving shaft 8, an annular groove 10 is provided on the surface of the traction roller 9, and a lifting rod 11 slidably connected to the annular groove 10 is fixedly connected to the lower end of the boosting piston 12, and a boosting piston 12 movably pulled by the traction roller 9 is slidably mounted in the lower end opening of the three-way pipe 103 connected to the lower chamber 102. By arranging the boosting piston 12 that can reciprocate up and down in the three-way pipe 103, the boosting piston 12 accelerates the airflow outside the chassis 1 to enter the upper chamber 101, thereby driving the lifting plate 21 and the precipitated solute to move upward to ensure the concentration of the dye solution;

[0028] On the other hand, the driving mechanism also includes a strong spring 13 welded in the lower end of the upper cavity 101, and a lifting sleeve 14 movably mounted on the upper section of the driving shaft 8 is welded on the strong spring 13, a rotating sleeve 15 is rotatably mounted on the lifting sleeve 14, a tensioning plate 16 is installed on the pin at the upper end of the driving shaft 8, and a limit groove 17 is provided in the tensioning plate 16, a limit spring 18 and a limit slider 19 welded to each other are arranged in the limit groove 17, a lifting plate 21 corresponding to the upper end opening of the three-way pipe 103 is connected to the pin on the limit slider 19, and a traction link 20 is connected to the lifting plate 21 by a pin between the rotating sleeve 15 and the lifting plate 21. It should be noted that the tensioning plate 16, the lifting plate 21 and the traction link 20 are arranged equidistantly circumferentially in a one-to-one correspondence, and the three are synchronously adjusted in the opening and closing state during the rotation process, thereby improving the contact degree with the dyeing liquid, achieving full mixing of the solute and the solution, ensuring the concentration of the dyeing liquid, and realizing uniform dyeing processing of the textile cloth by the dyeing liquid.

[0029] Please refer to the instruction manual for details Figure 1 The driving cylinder 4 is fixedly mounted on the chassis 1, and the lifting frame 5 is slidably mounted in the guide long hole 3. The booster roller 6 is located below the two steering rollers 2 to ensure that the textile cloth is in a taut state, so that it contacts the dyeing liquid smoothly, avoiding the textile cloth from being impregnated in place or fuel clogging and accumulation.

[0030] The driving motor 7 is fixedly disposed in the lower chamber 102 , and the driving shaft 8 is rotatably installed in the lower chamber 102 and the upper chamber 101 .

[0031] The limit spring 18 is welded in the lower end of the limit groove 17, and the limit slider 19 is slidably mounted in the limit groove 17. Under the traction and support of the limit spring 18 and the strong spring 13, the opening and closing plate 16, the lifting plate 21 and the traction connecting rod 20 can perform a resettable opening and closing movement to achieve a high degree of contact with the dyeing liquid and ensure the stirring drive effect.

[0035] The driving motor 7 is controlled to be turned on, and the output end of the driving motor 7 drives the driving shaft 8 to rotate, and the driving shaft 8 drives the traction roller 9 to rotate synchronously, and drives the booster piston 12 to move up and down in the three-way pipe 103 through the annular groove 10 and the lifting rod 11 to accelerate the airflow into the upper chamber 101, and drives the lifting plate 21 to move upward while driving the precipitated solute to move upward;

[0036] The driving shaft 8 drives the opening and closing plate 16 to rotate, so that the opening and closing plate 16 deflects up and down, and the lifting plate 21 drives the limit slider 19 to slide in the limit groove 17 to apply pressure to the limit spring 18. The lifting plate 21 that moves up and down drives the rotating sleeve 15 to rotate synchronously through the traction connecting rod 20, and drives the lifting sleeve 14 to move up and down;

[0037] The rotating opening and closing plates 16, the lifting plates 21 and the traction connecting rods 20 are continuously opened and closed during the rotation process to fully stir the dyeing liquid so that the dyeing liquid can be fully mixed to dye the textile fabric.
