Abstract
This utility model provides a double-sided computer-controlled high-density jacquard device, including a Z-shaped jacquard piece, which comprises a vertically arranged main body piece; a left wing plate extending from the upper left side of the main body piece, with a circular lever fulcrum on the left side of the left wing plate for engaging with the upper jacquard needle plate; multiple needle feet on the right side of the middle part of the main body piece; a right wing plate extending from the lower right side of the main body piece, with a locking slot on the right side of the right wing plate for engaging with the middle needle; and a locking block at the top of the main body piece for engaging with the reset triangle. The double-sided computer-controlled high-density jacquard device, through the Z-shaped jacquard piece + L-shaped needle plate layout + adjustable needle selector design, collaboratively solves the three major technical bottlenecks of high-density stitch adaptability, operational stability, and production efficiency, enabling the upper and lower jacquard devices to perform double-sided upper and lower jacquard processing simultaneously, resulting in high processing efficiency.
