Feeding device and feeding method for epoxy resin impregnated material production

The feeding device comprises an inner cylinder, a middle-layer isolation cylinder and an outer cylinder, a feeding port is formed in the top of the inner cylinder, an auger is arranged in the inner cylinder, a discharging port is formed in the bottom of the inner cylinder, the middle-layer isolation cylinder enables epoxy resin to be in a molten state and defoamed, and a heating rod is arranged on the cylinder wall of the middle-layer isolation cylinder. A spiral stirring rod coaxially rotating with the inner cylinder is arranged between the outer cylinder and the inner cylinder, a heating module is installed on the top of the outer cylinder, a telescopic buffer cylinder is arranged at the bottom of the outer cylinder, the telescopic buffer cylinder can adjust the volume through stretching and retracting, overlarge pressure is avoided, a butterfly valve is arranged at a finished material discharging port, and epoxy resin is stirred by the stirring rod to be defoamed after being melted, overflows to the outer
