Automatic winding device

The utility model discloses an automatic winding device. The automatic winding device comprises a workbench, a winding assembly, a rotating assembly, a lifting assembly and a storage frame wound with a heat preservation felt. The storage rack is rotatably arranged above the workbench; the winding assembly is detachably and rotatably arranged on the lifting assembly, and the winding assembly is used for fixing the starting end of the heat preservation felt; the lifting assembly is arranged above the workbench and used for driving the winding assembly to move up and down. The rotating assembly is rotationally arranged above the workbench and used for forcing the heat preservation felt to make contact with the winding assembly, and therefore the heat preservation felt is forced to be wound around the winding assembly through friction force. By means of the automatic winding device, automatic winding can be achieved, the stress uniformity of thermal field winding and the tightness of dense winding are easily impr
