The invention discloses automatic bristle loading equipment for a paint brush head in the technical field of paintbrush bristle loading machines. The automatic bristle loading equipment comprises a support frame, wherein a PLC control module is arranged on the surface of a left upright post of the support frame; a servo motor is arranged at the center of a cross beam of the support frame; a support plate is arranged at the top of the support frame; a disk penetrates in the top surface of the support plate; a bristle shaving and drawing combing mechanism neatly cuts broken filaments stretching from the end surface of an iron box; a push block of a filling and plugging mechanism pushes a small piece of rubber strip to move rightward; an electric fixture clamps the broken filaments to move rightward to finish bristle loading; finally, a manipulator transfers a finished product to a conveying belt, and the finished product is conveyed out and collected. The components of the device are distributed circularly, so that the overall structure is more compact; meanwhile, eight processes are finished through the disk rotation; the structural stability is high; the vibration is reduced; the automation degree is high; the use of labor force is reduced; the production cost is lowered; the market prospect is very broad.
