The outer wall of the engaging collar is connected to the scraping part through a scraping sleeve. A hole groove is opened at the bottom end of the scraping part, and a scraping blade is inserted into the hole groove. A sliding groove for the front end of the scraping sleeve to slide is arranged on the side wall of the scraping part.
[0010] Furthermore, bleaching and dyeing inner grooves are opened on the inner wall of the bleaching and dyeing chamber, and bleaching and dyeing sliders are slidably connected in the grooves of the bleaching and dyeing inner grooves.
[0011] Furthermore, the front end of the bleaching and dyeing slider is rotatably connected with a slider connecting piece, and the surface of the slider connecting piece is rotatably connected with a pressing roller, and the surface of the pressing roller is attached to the polyester-cotton fabric.
[0012] Furthermore, both ends of the left-right hand screw rod are supported on the side wall of the bleaching and dyeing chamber through brackets, and one end of the left-right hand screw rod extends outwards through the bracket to be provided with a turning handle.
[0013] Furthermore, the width of the scraping part is greater than the length of the guide roller, and the front ends of the two groups of scraping parts are attached to the polyester-cotton fabric.
[0014] Further, a limiting insertion cylinder is fixedly arranged at the side wall where the scraping blade extends into the scraping plate opening groove, and a screw hole flush with the port of the limiting insertion cylinder is opened on the surface of the scraping plate part.
[0015] Further, a limiting screw is spirally connected in the screw hole, and a positioning insertion rod inserted into the port of the limiting insertion cylinder is arranged at the front end of the limiting screw.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] Before the polyester-cotton enters the cavity of the bleaching and dyeing bin, the upper and lower two sets of scraping plate parts can scrape the polyester-cotton cloth, so that the fluff on the surface of the polyester-cotton cloth can be scraped off, thereby reducing the influence of the fluff on the dye in the bleaching and dyeing bin and improving the bleaching and dyeing quality. At the same time, the clamping distance at the front ends of the two sets of scraping plate parts can be adjusted at any time, so as to adapt to polyester-cotton cloths with different thicknesses. At the same time, the scraping blade with a quick-release structure can strengthen the work of removing fluff from the polyester-cotton fabric, and through the shape design of the scraping blade, the cotton fluff can move along the scraping blade to both sides, reducing the accumulation of cotton fluff.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4, including: a dyeing and bleaching tank 1, guide rollers 2 installed at both ends of the dyeing and bleaching tank 1 in the grooves, and a pressing roller 6 arranged in the cavity of the dyeing and bleaching tank 1. The polyester-cotton fabric moves from the right side to the left side, is soaked in the dye in the dyeing and bleaching tank 1, and guide rollers 2 are respectively installed at both ends of the dyeing and bleaching tank 1 in the grooves. The upper and lower groups of guide rollers 2 are driven by a motor to enable the guide rollers 2 to clamp and move the polyester-cotton fabric. A dyeing inner groove 3 is opened at the bottom position of the inner wall of the dyeing and bleaching tank 1, and a dyeing slider 4 is slidably connected in the groove of the dyeing inner groove 3. At the same time, the front end of the slider connecting piece 5 is rotatably connected to the slider connecting piece 5, and a pressing roller 6 is rotatably connected to the front end of the slider connecting piece 5. When the polyester-cotton fabric is generally at the bottom of the tank of the dyeing and bleaching tank 1 in the early stage, the entire slider connecting piece 5 and the pressing roller 6 can be rotated to the vertical state by the rotational connection between the slider connecting piece 5 and the dyeing slider 4. After being flattened, the slider connecting piece 5 and the pressing roller 6 can be rotated to the horizontal state, so that the pressing roller 6 can press the polyester-cotton fabric to carry out a certain degree of limiting.
[0025] The scraping part 8 is installed on the outer wall of the dyeing and bleaching tank 1, and two groups of scraping parts 8 are arranged on the upper and lower sides of the polyester-cotton fabric. The left and right hand screw rod 7 is installed on the outer wall of the dyeing and bleaching tank 1. Both ends of the left and right hand screw rod 7 are supported on the side wall of the dyeing and bleaching tank 1 through brackets. An engaging sleeve ring 9 is sleeved on the outside of the left and right hand screw rod 7 in an engaging manner. The outer wall of the engaging sleeve ring 9 is connected to the scraping part 8 through a scraping sleeve member 10. And in order to realize the connection between the scraping sleeve member 10 and the scraping part 8, a chute is opened on the side wall of the scraping part 8, so that the front end of the scraping sleeve member 10 is embedded into the chute, so that the scraping sleeve member 10 can slide radially in the chute and cannot be separated. At the same time, the scraping sleeve member 10 is composed of two sets of sleeve structures that can slide and sleeve. One end of the left and right hand screw rod 7 extends outward through the bracket to set a turning handle. When the turning handle at one end of the left and right hand screw rod 7 is rotated, the two engaging sleeve rings 9 can move simultaneously outside the left and right hand screw rod 7, and the engaging sleeve ring 9 can drive the scraping sleeve member 10, so that the two scraping parts 8 rotate at an angle. Both ends of the scraping part 8 are connected to the outer wall of the dyeing and bleaching tank 1 through a rotating shaft. Therefore, the front end distances of the two scraping parts 8 are different, and polyester-cotton fabrics with different thicknesses can be clamped.
[0026] A hole groove is formed at the bottom end of the scraping plate part 8, and a scraping blade 12 is inserted into the hole groove. The width of the scraping plate part 8 is greater than the length of the guiding roller 2, and the front ends of the two groups of scraping plate parts 8 are in contact with the polyester-cotton cloth. A limiting insertion cylinder 14 is fixedly arranged at the side wall of the scraping blade 12 extending into the groove of the scraping plate opening 11. A screw hole flush with the port of the limiting insertion cylinder 14 is formed on the surface of the scraping plate part 8. A limiting screw rod 15 is spirally connected in the screw hole. A positioning insertion rod 16 inserted into the port of the limiting insertion cylinder 14 is arranged at the front end of the limiting screw rod 15. The edge of the groove of the scraping plate opening 11 can rotate the scraping blade 12 at a certain angle, so that the front end of the scraping blade 12 can contact the polyester-cotton cloth, and the polyester-cotton cloth can be de-fluffed as the polyester-cotton cloth moves. The installation of the scraping blade 12 can be realized by placing the scraping blade 12 into the groove of the scraping plate opening 11, and then spirally connecting the limiting screw rod 15 with the screw hole at the scraping plate part 8, so that the front end of the positioning insertion rod 16 extends into the port of the limiting insertion cylinder 14, and the scraping blade 12 can be limited.
[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
