The invention discloses a vehicle-mounted resin rubber mixing mechanism. The vehicle-mounted resin rubber mixing mechanism comprises a vehicle body. A machine frame is arranged on the vehicle body. A first material storage device used for storing epoxy resin, a second material storage device used for storing a curing agent, and a mixing system capable of thoroughly mixing the epoxy resin with the curing agent are arranged on the machine frame, wherein a discharging outlet of the first material storage device and a discharging outlet of the second material storage device communicate with an acting port of the mixing system. A PLC control system capable of controlling the first material storage device, the second material storage device and the mixing system to work is further arranged on the machine frame and is in communication connection with the first material storage device, the second material storage device and the mixing system. Through the mechanism, the epoxy resin and the curing agent can be mixed thoroughly, the labor intensity of operators is relieved, and the production efficiency of wind turbine blades is improved.
