[0008] Preferably, the connector includes two flanges, which are respectively fixedly connected to the output end of the motor and the end of the rotating roller. The flanges of the motor and the rotating roller are correspondingly arranged and both are located outside the dyeing tank. The corresponding flanges are fixedly installed by bolts.

[0009] Preferably, the scraping assembly is rotatably installed inside the dyeing tank by a second motor. The scraping assembly includes two side scrapers and an arc-shaped scraper fixedly connected between the two side scrapers. The side scrapers are in contact with the inner sidewall of the dyeing tank, and the arc-shaped scraper is in contact with the inner bottom wall of the dyeing tank.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] A high color fastness printing and dyeing device for fabrics, such as Figures 1 to 3 As shown, the apparatus includes a dyeing box 1, an input roller 2 and an output assembly 3 mounted on both sides of the top of the dyeing box 1. Two fixed plates are welded to the top of the dyeing box 1. The input roller 2 is mounted between the two fixed plates via a motor. The output end of the motor passes through one of the fixed plates and is welded to one end of the input roller 2. The motor is mounted on one of the fixed plates via fastening bolts. A dyeing tank 4 for containing dye is opened at the top of the dyeing box 1. The inner bottom wall of the dyeing tank 4 is an arc-shaped concave surface that contacts the dye. A horizontally arranged rotating roller 5 is rotatably connected inside the dyeing tank 4. Stirring paddles 6 are welded to both ends of the rotating roller 5. The stirring paddles 6 are located inside the dyeing tank 4 and do not contact the inner wall of the dyeing tank 4. A conveying cylinder 7, coaxially arranged with the rotating roller 5, is welded to the outer peripheral wall of the rotating roller 5. The conveying cylinder 7 is located between the two stirring paddles 6, and its bottom is flush with the dye. The dye in the dyeing tank 4 is in contact with the dye. A scraping component 8 is rotatably installed inside the dyeing tank 4. The scraping component 8 abuts against the inner bottom wall and the inner side wall of the dyeing tank 4 respectively. The rotating roller 5 is rotatably installed inside the dyeing tank 4 by a motor 9. The top of the dyeing box 1 is provided with a receiving groove 10 to accommodate the rotation of the end of the rotating roller 5. There are two receiving grooves 10. The inner bottom wall of the receiving groove 10 is an arc-shaped concave surface and fits against the end of the rotating roller 5. The motor 9 is installed on the outer side wall of the dyeing box 1 by a fastening bolt 2. The output end of the motor 9 and the end of the rotating roller 5 are fixedly installed by a connector. The connector includes two flanges 11. The two flanges 11 are welded to the output end of the motor 9 and the end of the rotating roller 5 respectively. The flanges 11 of the motor 9 and the rotating roller 5 are correspondingly arranged and are both located outside the dyeing tank 4. The corresponding flanges 11 are fixedly installed by bolts.

[0020] The scraping assembly 8 is rotatably installed inside the dyeing tank 4 by a second motor 12. The scraping assembly 8 includes two side scrapers 801 and an arc-shaped scraper 802 welded between the two side scrapers 801. The side scrapers 801 are in contact with the inner side wall of the dyeing tank 4, and the arc-shaped scraper 802 is in contact with the inner bottom wall of the dyeing tank 4. The second motor 12 is installed on the outer side wall of the dyeing box 1 by a third fastening bolt. The output end of the second motor 12 passes through the side wall of the dyeing box 1, and the output end of the second motor 12 is welded to one of the side scrapers 801. The stirring paddle 6 does not contact the side scrapers 801 and the arc-shaped scraper 802 respectively. The first motor 9 and the second motor 12 are located on the outer side walls of the dyeing box 1, and both the first motor 9 and the second motor 12 are servo motors.

[0021] A heating frame 13 is placed at the bottom of the dyeing box 1, with an open top. The outer bottom wall of the dyeing box 1 and the dyeing tank 4 are respectively formed by arc-shaped convex surfaces. The inner wall of the heating frame 13 fits against the arc-shaped convex surface of the dyeing box 1. An inlet pipe and an outlet pipe are welded to one side of the heating frame 13, and valve one is installed on both the inlet pipe and the outlet pipe. A discharge pipe is welded to the outer wall of the dyeing box 1, and valve two is installed on the discharge pipe. Both valve one and valve two are existing technologies. Multiple support feet for contact with the ground are welded to the bottom of both the dyeing box 1 and the heating frame 13. The output assembly 3 includes an output roller 301, a pressure roller 302, and a guide plate 303. The pressure roller 302 is located directly above the output roller 301, and the two are axially parallel. Two mounting brackets are welded to the top of the dyeing box 1. Mounting plate 14, pressure roller 302 and output roller 301 are respectively set between two mounting plates 14. Pressure roller 302 and output roller 301 are in contact. Output roller 301 is mounted between the two mounting plates 14 by a second motor. The output end of the second motor passes through one of the mounting plates 14 and is welded to the end of the output roller 301. The second motor is mounted on one of the mounting plates 14 by a fourth fastening bolt. Pressure roller 302 is mounted between the two mounting plates 14 by a rotating shaft. Guide plate 303 is welded between the two mounting plates 14 and is inclined. Guide plate 303 is located below output roller 301 and its height gradually increases in the direction away from dyeing tank 4. The bottom of guide plate 303 extends into the interior of dyeing tank 4.

[0022] The dye is poured into the dyeing tank 4 through the top of the dyeing box 1. At this point, the dye contacts the bottom wall and both inner side walls of the dyeing tank 4, allowing it to settle at the bottom. The input roller 2 is driven to rotate by a starting motor, which in turn drives the rotating roller 5. The rotating roller 5 rotates the conveyor cylinder 7 and the agitator 6. The fabric is then conveyed into the dyeing tank 4 through the input roller 2. The fabric is then conveyed to the bottom of the conveyor cylinder 7 and comes into contact with the dye for dyeing. This process, where the fabric is dyed by the rotating conveyor cylinder 7, simultaneously agitates and disperses the dye inside the dyeing tank 4 through the rotation of the agitator 6, reducing the likelihood of sedimentation or clumping and improving the dyeing efficiency. To improve the uniformity of the dyeing effect, increase the color fastness of the fabric, and enhance the dyeing effect, the fabric is conveyed to the conveyor cylinder 7 without contacting the stirring paddle 6. The scraping component 8 is rotated 180 degrees from bottom to top inside the dyeing tank 4 by the starting motor 12. At this time, the two side scrapers 801 contact the inner side walls of the dyeing tank 4, and the arc-shaped scraper 802 contacts the inner bottom wall of the dyeing tank 4. The scraping component 8 scrapes off the dye attached to the inner bottom wall and inner side wall of the dyeing tank 4, thereby increasing the dye utilization effect. During the rotation of the scraping component 8, the stirring paddle 6 and the fabric do not contact the side scrapers 801 and the arc-shaped scraper 802. After the fabric is dyed in the dyeing tank 4, it is conveyed to the output component 3 for export through the conveyor cylinder 7.

[0023] When the fabric is conveyed to the output component 3, the output roller 301 is driven to rotate by starting the motor 2, and the pressure roller 302 is in contact with the output roller 301. The pressure roller 302 is rotatably installed between the two mounting plates 14, so that when the output roller 301 rotates, it drives the pressure roller 302 to rotate, which can convey the fabric between the pressure roller 302 and the output roller 301. The pressure roller 302 squeezes the fabric to squeeze out excess water, reducing the amount of water that drips directly onto the ground when the fabric is discharged from the dyeing tank 4. When the fabric is squeezed by the pressure roller 302, the water squeezed out from the fabric will drip onto the guide plate 303. Because the height of the guide plate 303 is gradually increased in the direction away from the dyeing tank 4, and the lower end of the guide plate 303 extends into the dyeing tank 4, the water dripping onto the guide plate 303 will flow back into the dyeing tank 4 along the inclined direction of the guide plate 303 for collection.

[0024] By opening valve one on the inlet pipe and introducing hot water or other heating liquid into the heating frame 13 through the inlet pipe, the liquid in the heating frame 13 can heat the dye that is in contact with the bottom wall of the dyeing tank 4 and located at the bottom of the dyeing tank 4. The dye at the bottom of the dyeing tank 4 can be heated to a suitable temperature. In conjunction with the stirring paddle 6, the dye in the dyeing tank 4 is stirred, so that the dye in the dyeing tank 4 is heated evenly, shortening the dyeing and fixing time of the fabric and improving the dyeing efficiency of the fabric.

[0025] When the agitator 6 and the conveyor cylinder 7 need to be cleaned or replaced, first remove the bolts to disconnect them from the output end of the motor 9 and the flange 11 on the rotating roller 5 respectively. Then lift the rotating roller 5 upward and drive the conveyor cylinder 7 and the agitator 6 to move respectively until the end of the rotating roller 5 no longer contacts the inner bottom wall of the receiving tank 10 and is removed from the receiving tank 10, so that the rotating roller 5 can be removed from the dyeing box 1 for cleaning or replacement of the conveyor cylinder 7 and the agitator 6.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
