DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a bleaching device for processing polyester knitted dyed fabrics, such as Figure 1-3 As shown, it includes a bleaching box 1, a first guide roller 2 is arranged on the top left side of the bleaching box 1, a second guide roller 3 is arranged on the top right side of the bleaching box 1, a third guide roller 4 is arranged in the middle of the inside of the bleaching box 1, a lifting plate 7 is arranged above the third guide roller 4, the bottom of the lifting plate 7 is fixedly connected to two symmetrically arranged mounting frames 6, the mounting frames 6 are rotatably connected to the pressure rollers 5, and the bleaching box 1 is provided with a lifting mechanism for adjusting the height of the lifting plate 7.

[0024] The bottom of the bleaching box 1 is fixedly connected with a water outlet pipe 16 , on which a valve is provided.

[0025] The lifting mechanism includes a vertical rod 8, a fixed seat 15, a top plate 9, a screw 14, a driving motor 11, a driving wheel 10, a driven wheel 12, and a transmission belt 13. The lifting plate 7 is provided with a sliding hole matching the vertical rod 8 and a screw hole matching the screw 14. The vertical rod 8 is slidably fitted in the sliding hole, and the screw 14 is threadedly fitted in the screw hole. The fixed seat 15 is fixedly connected to both sides of the bleaching box 1. A top plate 9 is arranged above the lifting plate 7. The two ends of the vertical rod 8 are respectively fixedly connected to the top plate 9 and the fixed seat 15. The bottom end of the screw 14 is rotatably connected to the fixed seat 15, and the top end of the screw 14 passes through the top plate 9 and is fixedly connected to the driven wheel 12. The top plate 9 is fixedly connected to the driving motor 11, and the output end of the driving motor 11 is fixedly connected to the driving wheel 10. A transmission belt 13 is transmission-connected between the driving wheel 10 and the driven wheel 12.

[0026] When the fabric needs to be bleached, the drive motor 11 is turned on, and the drive motor 11 drives the screw 14 to rotate. The rotation of the screw 14 causes the lifting plate 7 to move upward along the vertical rod 8 until the pressing roller 5 completely leaves the bleaching box 1, and then the fabric passes over the first guide roller 2 and the second guide roller 3, and the drive motor 11 is turned on again. The drive motor 11 reverses and drives the screw 14 to reverse, so that the lifting plate 7 descends, and the lifting plate 7 drives the pressing roller 5 to descend until the pressing roller 5 completely immerses the fabric in the bleaching box 1, so that the fabric immersion operation can be conveniently performed, which is easy to use.

[0027] The length of the lifting plate 7 is greater than the width of the bleaching tank 1 .

[0028] The inclination angle of the mounting frame 6 is greater than thirty degrees and less than sixty degrees.

[0029] The length of the vertical rod 8 is greater than the depth of the bleaching tank 1 .

[0030] When the pressing roller 5 and the bleaching box 1 need to be cleaned regularly, the pressing roller 5 can be lifted up to completely leave the bleaching box 1, and then the pressing roller 5 can be cleaned conveniently, thereby improving the cleaning efficiency.

[0031] Working principle: when the fabric needs to be bleached, the drive motor 11 is turned on, and the drive motor 11 drives the screw 14 to rotate. The rotation of the screw 14 causes the lifting plate 7 to move upward along the vertical rod 8 until the pressure roller 5 completely leaves the bleaching box 1, and then the fabric passes over the first guide roller 2 and the second guide roller 3, and the drive motor 11 is turned on again. The drive motor 11 reverses and drives the screw 14 to reverse, so that the lifting plate 7 descends, and the lifting plate 7 drives the pressure roller 5 to descend until the pressure roller 5 completely immerses the fabric in the bleaching box 1, so that the fabric immersion operation can be conveniently performed, which is easy to use.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
