The invention relates to a
coating device, in particular to an automatic interfacial agent
coating device for a
thermal insulation plate. The automatic interfacial agent
coating device comprises a material feeding part, a material coating part and a supporting frame; the material feeding part is used for feeding a material to the material coating part; the material coating part is supported through the supporting frame and comprises a driving motor, a material coating connection rod and a material coating
brush; the material coating connection rod comprises a cranking bar, a
coupling, a V-shaped rod, a connection rod and a coating rod; one end of the cranking bar is connected with a rotary shaft of the driving motor, and the other end of the cranking bar is connected with one end of the V-shaped rod through the
coupling; the V-shaped rod is connected with the coating rod through the connection rod, and the inflection point position of the V-shaped rod is movably connected with the supporting frame through a connection ring; the middle of the coating rod is movably connected with the supporting frame through a connection ring; and the coating rod fixes a material coating
brush and inclines downwards, and the material coating
brush communicates with the feeding part through a feeding
pipe. According to the automatic interfacial agent coating device for the
thermal insulation plate, a groove does not need to be carved in the
thermal insulation plate, the adhesion fastness is ensured while automatic coating of an interfacial agent for the thermal insulation plate is achieved, the production cost is reduced, and the production efficiency is improved.
