A multilayer flexible material conveying equipment with uniform speed and constant tension was developed. Through the unwinding mechanism and constant tension control, and by using the automatic deviation rectifying device to realize fine-tuning and precise positioning, the combination of multilayer flexible materials was realized; the servo motor was used to tract the multilayer flexible material, and the encoder was used for tracking and detection in the process so the multi-layer material could be effectively transported to the working position accurately with uniform speed and constant tension.The results show that the organic coordination of mechanical transmission, pneumatic device, electrical control and servo motor drive module makes the transportation of multi-layer flexible materials more stable and reliable.The research results provide reference for the optimization of production equipment innovation and production process of anti-epidemic materials.
