Problems solved by technology

[0002] At present, the dyeing and finishing equipment of polyester flat webbing is split type equipment. After coloring and dyeing, it is directly dried for drying. Infrared heating tubes are installed on the inner wall of the oven for direct high-temperature heating. The heating temperature in the oven is not uniform, resulting in polyester flatness. The webbing is deformed, resulting in uneven thickness and large color difference of the polyester webbing

After coloring and dyeing, the polyester flat webbing directly enters the oven, and the colored water on the polyester flat webbing drips into the oven, causing smoke to be generated in the oven during the high-temperature drying process, affecting the color of the polyester webbing, making the webbing black, and seriously affecting the appearance of the webbing.

[0003] In addition, maintenance is inconvenient, especially when replacing the infrared heating tube, the heating tube must be replaced after the oven temperature drops to normal temperature after the power is turned off
