The support plates are installed in the slide grooves opened inside the inlet and outlet 16, and the container 15 is supported by the slide grooves. The bottom of the recycling box 17 falls on the baffle fixed in the middle of the container 15, and the isolation plate is also fixed at the position corresponding to the baffle inside the recycling box 17, so that two spaces are also formed inside the recycling box 17; the lower collecting port 18 is installed above the container 15, the top is flush with the height of the box body 1, and the two sides are fixed to the inner wall of the connecting plate 2; the upper collecting port 19 is symmetrically installed above the lower collecting port 18; the connecting accessories are installed between the container 15 and the recycling box 17 and the lower collecting port 18; the fan 24 is respectively installed in the two spaces divided by the container 15.The connecting accessories include a first air duct 20, a second air duct 21, a fixing block 22 and a second supporting frame 23, wherein one end of the first air duct 20 is fixed to the bottom of the lower collecting port 18, and the other end is connected to one of the through holes opened at the top of the container 15. When the grey cloth passes over the lower collecting port 18, the fan 24 is started, and the negative pressure strength inside the container 15 is increased by the fan 24, so that the first air duct 20 at the top of the container 15 adsorbs the bottom of the grey cloth through the lower collecting port 18, collects dust, thread ends and other impurities on the surface of the grey cloth, and the impurities are driven by the negative pressure and fall from the bottom of the lower collecting port 18 through the first air duct 20 to the filter net at the bottom of the recovery box 17, and the filtered air is discharged again from the bottom of the recovery box 17. The second air duct 21 connects the container 15 and the upper collecting port 19, and a ventilation pipe is installed on the top of the through hole through another through hole at the top of the container 15 away from the first air duct 20, so that the ventilation pipe extends to The side of the connecting plate 2 is connected to one end of a hose on the ventilation pipe, and the other end of the hose is connected to the ventilation pipe at the top of the upper collecting port 19. When the fan 24 is started, the negative pressure inside the container 15 is transmitted to the upper collecting port 19 through the second air duct 21, and the dust and impurities on the upper surface of the grey cloth are adsorbed through the upper collecting port 19, thereby preventing the dust and impurities carried on the surface of the grey cloth from being immersed in the interior of the box body 1 along with the grey cloth. A fixed block 22 is fixed in the middle of both sides of the upper collecting port 19, and a second support frame 23 is installed on both sides of the upper collecting port 19. The bottom of the second support frame 23 is fixed to the top of the connecting plate 2, and a guide groove is provided on the side of the second support frame 23 corresponding to the position of the fixed block 22. The fixed block 22 is installed in the guide groove provided in the second support frame 23. The fixed block 22 can move back and forth through the guide groove. When the grey cloth passes between the lower collecting port 18 and the upper collecting port 19, the upper collecting port 19 can be moved to facilitate the stretching of the grey cloth.

[0033] A first guide roller 3 is installed on the top of the side of the connecting plate 2 away from the box body 1, and two groups of mutually symmetrical second guide rollers 4 are installed inside the box body 1.

A slide groove is provided on the side of the movable support plate 5, and the rotating shaft of the tensioning wheel 6 is installed inside the slide groove. A connecting frame 7 is sleeved on the rotating shaft at both ends of the tensioning wheel 6. A first support frame 8 is installed on the side of the movable support plate 5 away from the connecting plate 2. The bottom of the first support frame 8 is fixed to the top of the box body 1, and an electric telescopic rod 9 is fixed in the middle of the top of the first support frame 8. The telescopic end of the electric telescopic rod 9 is fixed to the center of the tensioning wheel 6, and the grey cloth is stretched from the surface of the first guide roller 3 to the surface of the tensioning wheel 6, and then passes through the bottom of the second guide roller 4 from the surface of the tensioning wheel 6. The connecting frame 7 is driven by the electric telescopic rod 9 to move, thereby changing the position of the tensioning wheel 6, adjusting the tension of the grey cloth, and keeping the grey cloth flat all the time.

[0034] Two groups of squeezing rollers 10 are installed on the top of the box body 1 away from the tensioning wheel 6. The bleached and dyed knitted fabric passes through the two groups of squeezing rollers 10 to squeeze the excess dye on the knitted fabric to avoid waste of dye.

[0035] A group of first stirring rods 11 are fixed in the middle position inside the box 1, and rotating shafts are arranged at both ends of the first stirring rods 11. One end of the rotating shaft is connected to the inner wall of the box 1, and the other end extends to the outside of the box 1. The horizontal position of the first stirring rod 11 is higher than the two groups of second guide rollers 4, so that when the knitted fabric passes through the bottom of the second guide rollers 4, it will not contact the first stirring rod 11. The two groups of second guide rollers 4 are fixed with second stirring rods 12 at the positions close to the sides of the inner wall of the box 1. The dye liquid inside the box 1 is stirred by the first stirring rod 11 and the second stirring rod 12 to avoid stratification of the dye liquid.

[0036] One end of the first stirring rod 11 is connected to a motor 13, and a support plate is provided at the bottom of the motor 13, and the support plate is fixed to the outer wall of the box body 1. The motor 13 is connected to the two groups of second stirring rods 12 through a transmission belt 14. The motor 13 drives the first stirring rod 11 to rotate, so that the first stirring rod 11 stirs the dye liquid between the two groups of second guide rollers 4. The first stirring rod 11 rotates while driving the transmission belt 14, and the transmission belt 14 drives the second stirring rod 12 to rotate, and stirs the dye liquid on both sides of the second guide roller 4, so as to achieve high-efficiency stirring of the dye liquid inside the box body 1 and ensure the uniformity of the dye liquid.

[0037] Working principle: the knitted fabric to be bleached and dyed is passed from the top of the first guide roller 3 between the lower collecting port 18 and the upper collecting port 19. When the knitted fabric cannot pass directly, the upper collecting port 19 can be moved in the guide groove of the second support frame 23 through the fixing block 22, so that the operator can get closer to the knitted fabric, which is convenient for moving the knitted fabric. When the knitted fabric passes between the lower collecting port 18 and the upper collecting port 19, the two sets of fans 24 are started, and the fans 24 generate negative pressure inside the container 15, and the container 15 passes through the first air duct 20 and the second air duct. The negative pressure is transmitted to the lower collecting port 18 and the upper collecting port 19 through the lower collecting port 18 and the upper collecting port 19, and the negative pressure removes impurities from the surface of the knitted fabric, so that the impurities on the surface of the knitted fabric are adsorbed by the lower collecting port 18 and the upper collecting port 19, and fall from the first air duct 20 and the second air duct 21 into the recovery box 17 installed above the fan 24, and the impurities are collected by the filter net installed at the bottom of the recovery box 17. When cleaning the impurities collected in the recovery box 17, the recovery box 17 can be opened from the sides of the container 15 and the connecting plate 2. The knitted fabric passing through the lower collecting port 18 and the upper collecting port 19 is pulled out from the top of the tension wheel 6, and then passed through the bottom of the two sets of second guide rollers 4, so that the dye liquid flows over the top of the second guide rollers 4, so that the knitted fabric is bleached and dyed by the dye liquid. During the bath dyeing, the motor 13 is started, and the motor 13 drives the first stirring rod 11 to rotate to stir the middle section of the dye liquid. While the first stirring rod 11 rotates, it drives the transmission belt 14, and the transmission belt 14 drives the second stirring rod 12 to rotate. The second stirring rod 12 rotates to stir the two sides of the dye solution, so that the dye solution is mixed more evenly, thereby improving the bleaching and dyeing effect of the knitted fabric. During bleaching and dyeing, the distance between the tensioning wheel 6 and the second guide roller 4 can be controlled by the electric telescopic rod 9, so as to adjust the tension of the knitted fabric, so that the knitted fabric can be kept flat, which is conducive to uniform bleaching and dyeing of the knitted fabric. The bleached and dyed knitted fabric passes between the two groups of squeezing rollers 10, and the excess bleaching and dyeing liquid on the surface of the knitted fabric is squeezed by the squeezing rollers 10, which is conducive to the subsequent drying of the knitted fabric.
