Description

Technical Field

[0001] This utility model relates to the field of overflow dyeing machine technology, specifically to an overflow dyeing machine dye recycling device. Background Technology

[0002] An overflow dyeing machine is a machine used for dyeing various knitted fabrics such as pure cotton, pure polyester, cotton-polyester blends, and spandex. Generally, the pre-treated fabric is sent to the overflow dyeing machine, where the dye liquor is applied to the fabric under high temperature and pressure, giving the fabric various colors.

[0003] For example, Chinese Patent CN118374940A discloses an overflow dyeing machine, which includes a dyeing machine body. A fabric outlet box is provided at the fabric outlet of the dyeing machine body. A water-squeezing device is provided on the fabric outlet box. The water-squeezing device includes a first water-squeezing roller, a second water-squeezing roller, and a recovery tank. The first water-squeezing roller and the second water-squeezing roller are arranged vertically and form a water-squeezing channel for the fabric to pass through between the first water-squeezing roller and the second water-squeezing roller. The first water-squeezing roller is located on the second water-squeezing roller and is connected to a driving component. The driving component is used to drive the water-squeezing roller to rise and fall to narrow the water-squeezing channel. The recovery tank is located below the water-squeezing roller. A return pipe is connected to the bottom of the recovery tank. The return pipe is used to guide the dye liquor in the recovery tank back into the overflow dyeing machine. This application reduces the adverse effects of dye liquor on the working environment during fabric output and saves resources. Traditional overflow dyeing machines recycle excess dye after dyeing the fabric and continue to heat it for reuse. However, when the dye is reheated after passing through the heat exchanger, the burrs on the fabric through which the dye passes are easily retained on the surface of the heat exchanger heating components, which can affect the heating efficiency of the heat exchanger heating components in the long run. However, the heating components inside the heat exchanger are inconvenient to disassemble and clean, which is quite troublesome. Therefore, an overflow dye recycling device is proposed to solve the above problems. Utility Model Content
