Description

Technical Field

[0001] The utility model relates to the technical field of yarn equipment, in particular to a knife holder with adjustable positioning of a blade for a yarn machine. Background Art

[0002] Chenille fabric is a fabric made of short fibers or filaments of different fineness and strength twisted together. Due to its plump down, soft touch, thick fabric and light texture, it is widely used in the field of home textiles and knitted clothing, forming a new highlight in product development.

[0003] The production of chenille is like a ring spinning machine. The decorative yarn rotates from the top of the machine into the center of the hollow spindle. The blade on the spindle cuts the decorative yarn at a certain distance. The decorative yarn falls between the core yarns and is output through rollers and guide wheels. In the prior art, the blade is directly and simply connected to the frame through a bracket, and the rear side is supported by a push rod. Since the blade is continuously under pressure during the working process, the blade will retreat a certain distance every time it works for a period of time. The staff needs to manually knock the push rod to push the blade forward. Since there is no benchmark for the knocking process, it relies entirely on the workers' experience, has manual errors, and is time-consuming and labor-intensive. Inaccurate blade adjustment position will affect the quality of subsequent processed products. Utility Model Content
