Twisting equipment for wool yarn

Abstract

The invention provides twisting equipment for wool yarn and belongs to the technical field of textile machinery. The equipment comprises a yarn return twisting disc, yarn return cylinders, a hairinessyarn removal ring, a drafting guide wheel, a yarn guide shaft and a swing-type yarn guide ring. The yarn return twisting disc is coaxially fixed to the upper end of a yarn return twisting supportingshaft, the four yarn return cylinders are evenly distributed on the yarn return twisting disc, and a fixing-type yarn guide ring is located above the four yarn return cylinders; a swing-type yarn guide rack is located above the fixing-type yarn guide ring, the hairiness yarn removal ring is located above the swing-type yarn guide rack, and the drafting guide wheel is located above the hairiness yarn removal ring; the swing-type yarn guide ring is installed on a swing-type yarn guide ring supporting shaft, the left end of a first swing rod is hinged to the right end of the swing-type yarn guidering supporting shaft, the right end of a second swing rod is hinged to an L-shaped supporting base, and the lower end of a swing driving piston rod of a swing driving air cylinder is hinged to the right end of the first swing rod and the left end of the second swing rod. According to the twisting equipment, the wool yarn can be quickly twisted, and yarn hairiness can be removed.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a wool yarn twisting device. Background technique [0002] Textile machinery covers all processing equipment from fiber weaving to garment molding, including chemical fiber machinery, spinning machinery, weaving machinery, knitting machinery, dyeing and finishing machinery, non-woven machinery, clothing machinery and textile equipment, etc. Twisting is a common process in textiles. If one end of spinning is held and the other end is turned, yarn can be formed. This process is called twisting. Twisting is the process of using rotary motion to twist the stretched thin sliver like twisting a towel when washing your face, so as to fix the longitudinal connection between fibers. The sliver is twisted around its own axis, which is called adding a twist. Twisting utilizes the bending and twisting of fibers, with bending creating coils and twisting creating twists. If one en...

Problems solved by technology

However, the structure of the common two-for-one twisting machine at present is relatively complicated, and the wool yarn formed after twisting has a lot of yarn hairiness, which seriously affects the quality of wool yarn
