A method of creating a design on complex curves and irregular contours of a protective helmet, quickly and without having to first disassemble the helmet. A design is transferred to a clear film/acetate, which is then exposed onto a photoresist mask, transferring the design to the photoresist mask. The mask is washed out creating blast-able areas in the design mask. The mask is adhered to an area of the helmet, which is otherwise covered with a sealed protective bag. Sandblasting/abrasive-blasting etches portions of the helmet surface through the blast-able area of the mask. Various colors or other special effects may be painted/applied onto the etched portions of the helmet surface. The protective bag and photoresist mask can be removed, and the painted areas buffed/polished in a final step.

A material pickup mechanism for automatic hat-making production line equipment includes an installation seat, a servo motor, and a rotating seat. A control box is arranged on one side of the installation seat through bolts. The servo motor is arranged at a bottom end of the installation seat through a positioning plate and positioning screw. The rotating seat is arranged at an output shaft of the servo motor through bolts. Top and bottom ends of the rotating seat are both connected with an installation plate through a fixed shaft. Adjusting holes are formed at a top of the installation plate. A hollow screw penetrates the adjusting hole. A bottom of the hollow screw is connected with an air outlet end of at least one sucking disc. The material pickup mechanism can continuously pick up materials to improve production efficiency. It is convenient to adjust positions between sucking discs.
