AI Technical Summary

Technical Problem

When switching between different yarn counts, the existing jacquard machines have inconvenient needle selection modules and blade arrangement changes, resulting in poor equipment versatility and inability to meet the diverse needs of weaving mills.

Method used

The eccentric wheel double-opening mechanism allows for flexible adjustment of the number and arrangement of heddles and jacquard heddles by adjusting the position and length of the swing shaft wall plate. Combined with the transmission connection of the eccentric wheel and push rod, it enables the independent movement of heddles and jacquard heddles, adapting to weaving needs with different hedles counts.

Benefits of technology

It improves the ease of adjustment of the loom, adapts to a wider range of heddle fabric weaving needs, and enhances the equipment's versatility and production flexibility.

Abstract

This utility model relates to the field of jacquard loom technology, and in particular to an eccentric wheel double-opening mechanism and jacquard loom, including a frame, a swing shaft wall plate on a connecting frame, a first heddle swing shaft and a first jacquard heddle swing shaft respectively arranged between the swing shaft wall plates at both ends and a first bottom beam, and a second heddle swing shaft and a second jacquard heddle swing shaft respectively arranged between the swing shaft wall plates at both ends and a second bottom beam. This utility model also discloses a jacquard loom. The eccentric wheel double-opening mechanism and jacquard loom obtained by this utility model, by adjusting the position of the swing shaft wall plate to match the appropriate length of the first heddle swing shaft, the first jacquard heddle swing shaft, the second heddle swing shaft, and the second jacquard heddle swing shaft, can adjust the number and arrangement of the lifting blades of the heddles and the jacquard heddles. Simultaneously, the opening of the jacquard heddles and the opening of the heddles can be adjusted according to actual needs, improving the ease of adjustment of the loom and making it suitable for a wider range of heddle fabric weaving needs.
