Dyeing equipment-SDF silk overflow dyeing machine

SDF silk overflow dyeing machine consists of dyeing tank, silk guide roller, feeding barrel, heat exchanger, filter, silk inlet and outlet rack and various pipelines. The structure is shown in Figure 10-20. When the fabric enters the dyeing tank, the water flow drives the fabric forward smoothly. Each dyeing tube is equipped with two independent silk guide pipes to separate the silk pieces to ensure that the fabric moves in the best condition and allows the fabric to be in contact with or immersed in the dye liquor at any part of the dye tank. The grooves are connected, so the color is even.
This machine adopts a large-diameter silk guide roller whose position can be adjusted up and down in the vertical direction to lift the fabric. The adjustable distance of the silk guide roller is 80mm. Generally speaking, when dyeing lighter and thinner fabrics, the silk guide roller can be adjusted closer to the liquid level in the dye tank, so that the fabric receives less lifting force. When the dyed fabric is thicker, the silk guide roller can be adjusted upward. Although the fabric is subject to greater tension, the distance between the fabric and the overflow pipe entrance increases when it leaves the silk guide roller, so it can be avoided. The fabric creates a blockage there.
The function of the silk guide roller is to prevent the fabric from slipping on the silk guide roller, thereby reducing the possibility of the fabric being scratched on the surface of the silk guide roller. The cross-section of the overflow pipe is oval, which can reduce the entanglement of the fabric and allow the fabric to fully unfold in the overflow pipe to avoid disorder. A reverse liquid feeding device is installed between the liquid level of the dye tank and the silk guide roller, so that the fabric can reach the silk guide roller from the dye solution in an open-width state, thereby reducing wrinkles on the fabric during the dyeing process. At the same time, it can also reduce the temperature difference between the fabric on the silk guide roller and the dye solution to ensure uniform coloring.

The tail of the overflow pipe is higher and gradually tilts forward toward the machine head, which can make the fabric move more naturally to the front of the dye tank during operation, reduce the tension of the fabric, and reduce the friction between the fabric and the dye tank. friction between them. In addition, it is equipped with a flow control valve and a return water regulating valve, which can control the running speed of the fabric in the dye tank to avoid clogging and scratches caused by the fabric running too fast, and also avoid unnecessary damage caused by the fabric running too slow. Additional tension.
The SDF silk overflow dyeing machine is specially designed for dyeing light and thin silk fabrics.
