Automatic gluing machine capable of accelerating cooling of glue layer

The utility model relates to the technical field of coating equipment, in particular to an automatic glue coating machine capable of accelerating cooling of a glue layer. The hot glue coating device comprises a supporting frame and a glue coating plate, the glue coating plate is assembled on the inner side of the supporting frame, an adjusting mechanism is assembled between the supporting frame and the glue coating plate and used for adjusting the position of the glue coating plate, and a cooling mechanism is assembled on the inner side of the adjusting mechanism and used for cooling hot glue coated on the metal surface. The adjusting mechanism comprises a horizontal adjusting assembly and a vertical adjusting assembly. Through the structural design of the adjusting mechanism and the cooling mechanism, the device can be used for conveniently coating a thicker metal plate, meanwhile, when a coating with higher temperature is used for coating, the cooling of hot glue can be accelerated during coating, the worki
