The invention relates to a plate edge sealing treatment device for plane design, which comprises a back plate, a guide
assembly, a belt supply
assembly and a shearing
assembly. The front surface of the back plate is attached to the back surface of a plate, the guide assembly is attached to the front surface of the plate, and an n-shaped
lap joint piece is in
lap joint with the upper end of the plate; the device is pushed to move from one end of a plate to the other end of the plate, in the moving process, a glue solution stored in a glue solution storage box drips on a glue
coating wheel through a glue supply
pipe, the glue
coating wheel rotates under the action of
friction force, the upper end of the plate is evenly coated with the glue solution, the front end of an edge sealing belt is bent backwards under the blocking action of a baffle and the side edge of the plate, and the edge sealing belt is fixed. The edge sealing belt is pressed below the pressing roller, the edge sealing belt is pasted on a plate for edge sealing under the
extrusion effect of the pressing roller, after edge sealing is completed, the edge sealing belt is
cut off through the shearing assembly, deflection or bubbles cannot occur between the edge sealing belt and the plate, the attractiveness of a finished product is good, and the small-batch edge sealing requirement of a plane designer during home decoration design is met.
