Abstract

The work aims to improve the uniformity of working surface temperature of aluminum-plastic heat sealing heating roll and enhance the sealing effect of aluminum-plastic blister packaging machine. The temperature field simulation model of aluminum-plastic heat seal heating roll was constructed and verified through experiment to simulate the working surface temperature of the heating roll. The effect trend of the internal structure of the roll body on its working surface temperature was studied, and the internal structure of the improved heating roll was determined and optimized accordingly. When the thickness of the thermal conductive copper strip d_t was 10 mm and the distance between the heating tube and the heating roll d_s was 14 mm, Δt_max, t_fand T_u were 1.01 ℃, 0.38 ℃ and 0.9957 76 respectively, which increased by 6.39 ℃, 2.19 ℃ and 0.01 respectively compared with the Δt_max, t_f and T_u of traditional heating rollers. This research effectively enhances the heat transfer efficiency inside the heating roller, reduces the uniformity time of the working surface temperature of the heating roller, and lowers the production energy consumption in the aluminum-plastic heat sealing process, providing theoretical support and technical guidance for related research in the field of aluminum-plastic heat sealing.
