Design of a Fully Automatic Three-Dimensional Loom Control System Based on PLC

This study proposes a PLC-based fully automatic control system for 3D flat looms to address the limitations of current domestic 3D textile production equipment. First, the shortcomings of existing control systems (e.g., low efficiency and mechanical instability) are analyzed. Subsequently, the hardware and software designs of the proposed system are elaborated, including the selection of key components such as the Haoxin H226IM PLC and Sqeldt CS1-U magnetic switches. Experimental results demonstrate that the system achieves a weaving efficiency of 120 mm/h for shallow crossbend fabrics under fully automatic operation.
