Technical Field
[0001] The utility model relates to the technical field of coil unwinding, in particular to a coil preheating device. Background Art
[0002] At present, coils need to be unwound by unwinding machines for subsequent processing and production. However, due to the different material properties of coils, there are still some problems in unwinding under conventional natural temperature environments: 1. Because some materials are relatively hard at relatively low temperatures, unwinding is not smooth; 2. Some coils are metal coils, such as aluminum coils, which can be used in the production of aluminum composite panels. The surface of aluminum coils is generally painted to make the surface color of the composite panels diverse. Then, because the force on the coils is very large when they are curled, the paint between the coils will have a certain viscosity. After unwinding at room temperature, there will be paint indentations on the surface of the coils, affecting the surface quality. At present, there is no preheating device to preheat the unwound coils. Utility Model Content
