Protective edge sealing device for plate manufacturing

The utility model relates to the technical field of edge sealing, in particular to a protective edge sealing device for plate manufacturing, which comprises a base and a top plate, the base is fixedly connected with the top plate through support columns, a positioning mechanism is arranged above the top plate, the upper surface of the top plate is fixedly connected with a protective shell, and a protective mechanism is arranged above the top plate. When the sliding rod is pushed upwards, the spring is compressed, the sliding rod moves between the pin rod and the pressing plate, the cylinder drives the pin rod to move, the pin rod drives the sliding rod to move, the pressing plate rotates while moving upwards, the pressing plate drives the first clamping block to move, the plate is placed on the second clamping block, the sliding rod is loosened, and the spring drives the sliding rod to slide reversely under the elastic effect. The first clamping block is attached to the upper surface of the plate, the first c
