The utility model relates to a packaging mechanical device, in particular to a heating conductive and pressure adjusting device for a gluing machine. The utility model comprises a heating conduction device and a pressure adjustment device. The heating conduction device comprises a roller shaft (1) covered with an insulation jacket (12) and a spiral heating wire (13) wound around the insulation jacket (12). Its structural features are: the outer surface of the heating wire (13) is covered with a rubber surface (7), the two ends of the roller shaft (1) are covered with a conductive sleeve (6), and the heating wire (13) and the conductive sleeve ( 6) riveting, the conductive sleeve (6) is in contact with the conductive block (8) attached to the conductive block (9) on the base (11), and the conductive strip (9) is fixed on the base (11) Conductive screws (10) are connected. The utility model solves the shortcomings of the prior art, and has the advantages of good conductive contact, good heating effect, convenient pressure adjustment, installation and maintenance among the rollers, and long service life.
