The invention discloses a pressing pasting device for assisting the plate-type edge sealing technology, and belongs to the technical field of plate-piece edge sealing devices. The pressing pasting device is characterized by comprising a base; an installing plate is arranged on the base, and a horizontal adjusting mechanism is connected to the installing plate; a plurality of edge sealing pressing mechanisms are sequentially arranged on the installing plate in the advance direction of a to-be-sealed plate material, and a first horizontal micro-adjusting mechanism is connected to each the edge sealing pressing mechanism; the edge sealing pressing mechanisms are mainly composed of installing frames, fixing swinging rods arranged on an installing frames in the vertical direction and pressing pasting wheels movably arranged on the fixing swinging rods; the lower ends of the fixing swinging rods are hinged to the installing frames, and the upper ends of the fixing swinging rods are connected with the installing frames through a second horizontal micro-adjusting mechanism. The pressing pasting device for assisting the plate-type edge sealing technology is reasonable in structure, flexible in using and good in pressing pasting effect and is used for plate-piece edge sealing.
