Electric piston type paste pump

The utility model relates to the field of space composite membrane material production, in particular to an electric piston type paste pump which comprises a motor, a swing piece, a swing rod, a piston rod, a piston cylinder, a one-way piston ball and a one-way resistance ball. The motor is connected with one end of the swing piece, and the two ends of the swing rod are hinged to the other end of the swing piece and one end of the piston rod respectively. The other end of the piston rod is arranged in the piston cylinder in a sliding mode, and the one-way piston ball is arranged at the other end of the piston rod. A paste inlet hole and a paste outlet hole are respectively formed in two ends of the piston cylinder; and the one-way resistance ball is arranged at the paste inlet hole. The electric piston type paste pump is accurate in control, capable of achieving frequency conversion control, accurate in control over high-viscosity, small-flow and short-distance conveying, capable of reducing mass, convenient
