Liquid material preparing and blending cylinder

The utility model relates to the technical field of material blending equipment, and discloses a liquid material preparing and blending cylinder which structurally comprises a blending cylinder, a motor arranged at the top end of the blending cylinder, a driving part arranged on one side of the motor, a mounting groove formed in the inner wall of the blending cylinder, and a suction part mounted in the mounting groove. The liquid mixing device has the advantages that the driving mechanism is additionally arranged at the top end of the mixing cylinder to drive the piston in the suction assembly on one side of the cylinder wall to move in the connecting pipe in a reciprocating mode through the cam, so that liquid materials are sucked into the suction port in the coil pipe at the bottom end, the filter screen is arranged in the suction port, and therefore the liquid materials can be effectively mixed. The connecting pipe is pushed by the piston, so that the liquid in the coil pipe is flushed out, in conclusion,
