Technical Field

[0001] The utility model relates to an opening device for an edge-letter jacquard machine, belonging to the technical field of textile machinery. Background Technique

[0002] The edge-letter jacquard machine is a textile machine that can weave words or patterns at the edge of the fabric; the working principle of the edge-letter jacquard machine is to control the interweaving mode of the warp and weft to form a specific pattern or text at the edge of the fabric. When the warp and weft are interwoven, the heald lifting movement needs to be realized through an opening device, that is, according to the requirements of the fabric organization, the warp is divided into upper and lower layers to form a shed so that the weft can be introduced for interweaving.

[0003] The existing opening device makes a uniform circular motion with a circular positioning disk, and drives the connecting heald frame to realize the heald lifting movement through a connecting rod; due to the uniform circular motion, when the heald is lifted, the stationary time of the opening is short, and the size of the opening is fixed, resulting in the sword head often scraping and breaking the color threads on both sides when weaving the edge-letter variety, seriously affecting the weaving speed and efficiency, increasing the weaving cost, not only increasing the workload of the weavers on the machine, but also bringing quality problems such as broken defects and wrong threading to the woven products.
