PURPOSE: A material supplying and mixing proportion adjusting device always maintains the amount of material supplied to a hopper to improve convenience and efficiency of injection molding. CONSTITUTION: A device comprises a first and a second material supplying pipes(10-1, 10-2), a first and a second suction pipes(20), material amount detecting sensors "B"(50), a warning indicator(60), a first and a second air supplying devices(30-1, 30-2), timers(T1, T2), a material amount detecting sensor "A"(40) and a control part(70). The material supplying pipes(10-1, 10-2) supply material into a hopper(80). The suction pipes(20) are connected with the material supplying pipes(10-1, 10-2) to suck in material in a material storage(110). The material amount detecting sensors "B"(50) are installed under the suction pipes(20) to detect the amount of material in the material storage(110). The warning indicator(60) shows the amount of material in the material storage(110). The air supplying devices(30-1, 30-2) supply compressed air to the suction pipes(20) to supply material in the material storage(110) to the hopper(80). The timers(T1, T2) control the driving of the air supplying devices(30-1, 30-2) independently to adjust the mixing proportion of the material supplied to the hopper(80). The material amount detecting sensor "A"(40) is installed in the hopper(80) to detect the amount of material inputted.
