Energy-saving and environment-friendly coating device capable of efficiently controlling coating injection volume

The invention provides an energy-saving and environment-friendly coating device capable of efficiently controlling the coating injection volume. The device comprises a main body; discharging pipes arearranged in the main body; a fixing part is arranged on the outer side of the corresponding discharging pipe; a groove is formed in the corresponding fixing part; a fixing piece is fixedly arranged on the inner wall of the corresponding groove; a spring mechanism is connected to the right side of the corresponding fixing piece; and a movable part is fixedly connected to the right end of the corresponding spring mechanism. According to the energy-saving and environment-friendly coating device capable of efficiently controlling the coating injection volume, fixed gear rods are driven to move outwards through meshing connection of driving gears, so that movable baffles are mutually opened, coating injection is facilitated, the coating injection amount is determined through the opening size of the movable baffles, an
