Principles and Design of the Automatic Strapping Equipment for Solid Propellants

Abstract

To ensure the positional accuracy of the product after assembly, grouped rod-like solid propellants must be pre-strapped with cotton thread. The current manual operation involves operators being exposed to hazardous and explosive materials over long periods, suffers from limited efficiency, and presents high operational difficulty. To address these issues, an automatic strapping equipment for solid propellants was designed. This equipment employs a PLC as the control core and utilizes hardware components such as servo motors, cams, and cylinders to achieve an automatic strapping speed of 4 minutes per bundle. This significantly improves strapping efficiency and consistency while reducing operational difficulty.
