Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a printing and dyeing drying device. Background Art

[0002] After dyeing and printing, the fabric needs to be dried to fix the dye or paint on the fabric. There are many ways to dry it, such as hot air drying, which transfers heat through hot air convection to evaporate the moisture in the fabric. It is suitable for most textiles, especially those that are temperature sensitive or need to be dried evenly.

[0003] At present, a large number of hot air nozzles are arranged on the hot air ducts laid in the hot air drying devices to blow hot air to the fabrics, and the positions of the hot air nozzles are mostly fixedly distributed, which also makes the blowing position of the hot air fixed, affecting the uniformity of fabric drying. Some drying devices that can control the movement of the hot air nozzles require special power equipment to drive the movement of the nozzles, which increases the drying cost. Therefore, this scheme proposes a printing and dyeing drying device, which is based on the self-service principle and uses the movement of the fabric to provide a power source for the movement of the nozzles.
