Content of the utility model

[0005] In order to reduce the impurities on the surface of the extrusion roller and improve the quality of the cloth, the present application provides a cloth discharging device of an overflow dyeing machine.

[0006] The cloth discharging device of the overflow dyeing machine provided by the present application adopts the following technical scheme:

[0007] A cloth discharging device of an overflow dyeing machine, comprising a rack, two extrusion rollers rotatably connected to the rack, the rack is used to be connected with the body of the dyeing machine, the rack is connected with a rotating piece, the rotating piece is used to drive the extrusion roller to rotate, the two extrusion rollers are distributed in the vertical direction, one side of the extrusion roller is provided with a scraper, the length direction of the scraper is consistent with the length direction of the extrusion roller, one side of the scraper along the width direction is in contact with the circumferential side of the extrusion roller, the scraper is used to scrape off the impurities from the circumferential side of the extrusion roller, the rack is connected with a moving assembly, the moving assembly is used to drive the scraper to move and make the scraper close to or away from the extrusion roller.

[0008] By adopting the above technical scheme, after the cloth dyeing is completed, the cloth passes through the two extrusion rollers, the two extrusion rollers extrude the cloth, so that the excess dye liquid in the cloth is extruded out, thereby reducing the dye liquid in the cloth. After long-term use, impurities are easily adhered to the circumferential side of the extrusion roller. When the impurities are adhered to the circumferential side of the extrusion roller, the moving assembly drives the scraper to move and makes the scraper close to the extrusion roller, so that one end of the scraper is in contact with the extrusion roller. The rotating member drives the extrusion roller to rotate, so that the scraper scrapes off part of the impurities adhered to the surface of the extrusion roller, reduces the impurities on the surface of the extrusion roller, reduces the pollution of the impurities to the cloth, and improves the quality of the cloth.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When impurities adhere to the periphery of the extrusion roller, the moving component drives the scraper to move and bring the scraper closer to the extrusion roller, so that one end of the scraper contacts the extrusion roller. The rotating component drives the extrusion roller to rotate, so that the scraper scrapes away some of the impurities adhering to the surface of the extrusion roller from the surface of the extrusion roller, reducing the impurities on the surface of the extrusion roller, reducing the contamination of the fabric by the impurities, and improving the quality of the fabric.

[0025] 2. When the scraper cleans impurities, the impurities are scraped off from the surface of the extrusion roller and fall into the collection box, which facilitates the winding of impurities and reduces the amount of impurities falling into the surrounding environment, thus reducing the pollution of the surrounding environment by impurities.

[0026] 3. After the extrusion rollers extrude the fabric, excess dye liquor is squeezed out of the fabric and drips into the recycling bin, thereby reducing the amount of dye liquor dripping into the surrounding environment and reducing the pollution caused by the dye liquor. The dye liquor passes through the first filter plate, which filters the dye liquor and reduces impurities in the dye liquor. Attached Figure Description
