Hydrogel smearing device for cooling patch production

The utility model relates to a hydrogel smearing device for cooling patch production, which comprises a horizontally arranged conveying table with a U-shaped vertical section, and a glue spraying mechanism, a trowelling mechanism and a press-fit forming mechanism for hydrogel forming are sequentially erected on the conveying table. A cooling mechanism communicating with the interior of the conveying table is installed between the press-fit forming mechanism and the trowelling mechanism, a plurality of horizontally-distributed edge pressing wheels are rotationally connected to the positions, located on the two sides of the trowelling mechanism, of the bottom of the interior of the conveying table, and the edge pressing wheels located on the same side of the trowelling mechanism are located on the two sides of the conveying table correspondingly. The trowelling mechanism comprises a first inverted-U-shaped support erected on the conveying table, a trowelling roller with the adjustable height position is install
