Equipment for applying polytetrafluoroethylene to stainless steel water tank inner container and application method of equipment

The invention belongs to the field of manufacturing of stainless steel water tank inner containers, in particular to equipment for applying polytetrafluoroethylene to a stainless steel water tank inner container. The equipment comprises a fixed workbench, a guide rail and an auxiliary workbench, wherein the guide rail is connected with the fixed workbench, and the auxiliary workbench is mounted onthe guide rail in a sliding manner. A transmission mechanism is arranged inside the fixed workbench. A driving chuck is arranged outside the fixed workbench. The transmission mechanism is in transmission connection with the driving chuck. The auxiliary workbench is provided with a driven chuck. Compared with the prior art, the equipment is simple and steady in structure and capable of well fixingthe stainless steel water tank inner container to the portion between the driving chuck and the driven chuck; the transmission mechanism can drive the driving chuck to rotate, and thus the stainlesssteel water tank inner cont
