The utility model relates to the field of belt wheel transmission devices, and particularly discloses an adjustable belt tensioning device which comprises a wheel seat, a swing arm assembly with a swing arm and a tensioning wheel seat, a tensioning wheel with a counting hole, an infrared sensor, an adjusting assembly with a first rotating block, a second rotating block and a connecting rod, a first nut assembly and a second nut assembly. And the elastic assembly is provided with a spring and a third nut assembly. The tensioning wheel is installed at the end of the swing arm assembly, the rotating angle of the swing arm assembly can be conveniently adjusted and positioned through the adjusting assembly, so that the position of the tensioning wheel is changed, the swing arm assembly can elastically float through the elastic assembly, and therefore the tensioning wheel can be adjusted conveniently. The elastic hardness of the tensioning wheel can be adjusted by adjusting a nut assembly in the elastic assembly, t
