Large-flow glue coating double-screw pump

The utility model discloses a high-flow glue coating double-screw pump, and belongs to the technical field of double-screw pumps. The two main pump bodies are arranged in parallel, the belt wheels are upwards arranged on the gears of the pump bodies, operation of the two main pump bodies can be achieved through a single driving motor, the two pumps are driven by one motor to work, the output pressure of the two pumps can be consistent, and then the output pressure is stable; the surfaces of the two-head driving screw and the three-head driven screw are coated with hydrogenated butadiene rubber, so that the overall wear resistance of the two-head driving screw and the three-head driven screw can be effectively improved, and the service life is prolonged; the horn-shaped grooves and the bevel grooves are formed in the shaft necks of the two-head driving screw and the three-head driven screw, lubricating oil can be added into the horn-shaped grooves and the bevel grooves, the shaft neck positions are lubricated,
