Description

Technical Field

[0001] The utility model belongs to the technical field of loom dobby shedding, and relates to a loom servo dobby shedding structure. Background Art

[0002] Loom shedding refers to the action performed by the shedding mechanism during the weaving process, separating the warp yarns to form the shed, allowing the weft yarns to pass through. This shedding action is accomplished by the shedding mechanism, which controls the order in which the warp yarns are raised and lowered, according to the fabric weave requirements. During loom operation, shedding dobby adjustment is crucial to ensuring stable and precise shuttle movement. Failure to maintain this adjustment, resulting in the shuttle's inability to maintain stable movement, can lead to a range of problems.

[0003] During the weaving process, the shuttle must weave between the warp threads at a fixed time and position to interweave the weft threads. If the shuttle's movement is unstable, the position and tension of the weft threads will be affected, resulting in quality issues such as weft skew and weft bend in the fabric. These issues not only affect the appearance of the fabric but can also affect its performance.

[0004] If the shuttle is subjected to unstable forces during its movement, friction between it and the machine parts will increase, accelerating equipment wear. Over time, this unstable movement may also cause equipment failure, affecting production efficiency and safety. Therefore, there is an urgent need for a loom servo dobby shedding structure to solve the above problems. Utility Model Content
