Porous plastic sealing ring production equipment

The porous plastic sealing ring production equipment comprises a supporting frame, supporting legs are fixedly connected to the bottom end of the supporting frame, a conveying belt with holes is installed on the supporting frame, and a portal frame is fixedly connected to the supporting frame; according to the multi-hole type plastic sealing ring production equipment, by arranging the positioning assembly and the cutting assembly, when the sealing ring is positioned, the hydraulic cylinder drives the push rod to move, so that the positioning assembly is pushed to move downwards, the sealing ring is cut, and the sealing ring is cut. The cylindrical air bag is expanded through starting of the motor, so that the positioning plate is diffused along the axis, the inner ring of the sealing ring is attached to the outer wall of the positioning plate, and the edge of the sealing ring is cut and trimmed through the action of the cutting blade; therefore, the problem that in the prior art, due to inaccurate positioning
