Description

Technical Field

[0001] The utility model relates to the technical field of dyeing equipment, in particular to a polyester fabric dyeing and finishing device based on one-bath dyeing. Background Art

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester formed by the polycondensation of organic dibasic acid and diol. It is a polymer compound. It is the largest variety of synthetic fiber at present. The biggest advantage of polyester fiber is its good wrinkle resistance and shape retention, and it has high strength and elastic recovery ability.

[0039] Working principle: the fabric to be bath-dyed is passed between the fixed conveying roller 4 and the movable transmission roller 5. The movable transmission roller 5 can automatically adjust its height according to the thickness of the fabric. Then the fabric is passed through the bottom of the rotating roller 8 close to the fixed conveying roller 4. Then the fabric falls to the top of the tensioning roller 12. Then the fabric is pulled from the top of the tensioning roller 12 to the bottom of the second set of rotating rollers 8. Then the fabric is pulled from the bottom of the rotating roller 8 to between the two sets of pressure rollers 14. The fabric is passed between the two sets of pressure rollers 14 to be stretched into a "W" shape. Dye liquid is injected into the bath dye pool 1. The minimum water level of the dye liquid should be above the top of the rotating roller 8. The fixed conveying roller 4 and the pressure roller 14 are rotated to drive the fabric. When the fabric passes from the bottom of the rotating roller 8 , will come into contact with the dye liquid, and the dye liquid will dye the fabric. The height of the tensioning roller 12 can be adjusted by the hydraulic cylinder 10, so as to adjust the tension of the fabric. When the fabric passes through the inside of the pressing roller 14, it is squeezed by the two groups of pressing rollers 14 to reduce the dye liquid on the surface of the fabric, which is convenient for subsequent drying of the fabric. When the fabric is dyed, the motor 21 can be started, so that the motor 21 drives the movable block 22 to move through the screw rod 20, thereby driving the first filter screen 24 to salvage and filter the impurities floating in the dye liquid, and the second filter screen 27 can be extended according to the width between the fixed conveying roller 4 and the tensioning roller 12, so as to filter and salvage the impurities in the dye liquid to a greater extent.
