The invention provides a uniform solution feeding system for multi-nozzle electrospinning mass production equipment. The system comprises a spinning solution preparing device, a spinning solution distributing device and a spinning unit, wherein the spinning solution distributing device comprises a spinning solution distributing tank, a row of solution distributing ports are formed in the distributing tank at equal intervals, a return pipe is arranged and connected to the head end and tail end of the distributing tank, a solution distributing valve is arranged at the position, near the tail end of the distributing tank, of the return pipe, and a pressure sensor capable of controlling opening and closing of the solution distributing valve is arranged in the distributing tank; the spinning unit comprises a spinning pipe connected with the distributing tank, a row of spinning nozzles are arranged on the spinning pipe at equal intervals, and a depressurization port is formed in the end, away from the distributing tank, of the spinning pipe. By means of the spinning solution preparing device, the spinning solution distributing device and the spinning unit which are arranged in an integrated mode, preparation and uniform distribution of spinning solutions can be achieved, solutions can be fed to tens of thousands of spinning nozzles uniformly at the same time, so that the spinning solutions sprayed out of the tens of thousands of spinning nozzles have the same pressure and same flow rate, and mass production of electrospinning is achieved.
