Automatic putty powder production line

The invention relates to the technical field of putty powder production, in particular to an automatic putty powder production line which comprises a storage tank, supports are arranged on the two sides of the bottom end of the storage tank, a discharging pipe is arranged at the bottom end of the storage tank, a first feeding mechanism is arranged at the bottom end of the discharging pipe, and a stirring tank is arranged on one side of the storage tank. Raw materials are guided into the first feeding mechanism through the discharging pipe and then guided into the stirring tank through the first feeding mechanism, then the electromagnetic valve is opened, stirring ingredients in the ingredient tank are sequentially guided into the second feeding mechanism, then the second feeding mechanism is guided into the stirring tank through the connecting pipe, and the ingredients can be quantitatively added through the electromagnetic valve; and after stirring is completed, putty powder is guided into a pneumatic pipeli
