[0002] Loom, also known as weaving machine, spinning machine, loom, cotton spinning machine, etc., early looms were all driven by manpower. With the development of mechanical structure, the current looms are basically mechanically driven or CNC automatic looms. To make a certain fabric, the loom must divide the warp yarn into two layers, forming a shed for the weft insertion device to pass through. The opening movement of the warp yarn determines the organization of the fabric, affects the weft insertion process, and affects the variety, quality and weaving efficiency of the fabric. The opening mechanism of the existing industrial core loom is generally opened by a single-sided multi-arm lifting heald frame. With the needs of production development and the increase in the width of the loom, the requirements for core fabrics are getting higher and higher. The warp tension of core fabrics is large. The existing looms are single-sided multi-arm openings, and often have problems such as insufficient power, unstable opening, and high failure rate. The loom cannot operate reliably.
