Embodiment Construction

[0014] like figure 1 and 2 As shown, the twisting mechanism of the semi-worsted roving frame according to this embodiment includes a flyer 1, a spindle 2 with a roving bobbin 5 on the outer cover, and a presser palm 4, and the top of the flyer 1 has a side hole for the sliver to pass through. 10, and a notch 13 is opened at the top. The flyer 1 includes a hollow arm 11 and a solid arm 12 arranged symmetrically, and a yarn guide groove 3 extending along the length direction of the hollow arm 11 is opened on the hollow arm 11 . The pressure palm 4 includes a pressure palm rod 40 with one end connected to the lower end of the hollow arm 11 and arranged horizontally, and a pressure palm leaf 41 rotatably disposed on the other end of the pressure palm rod 40 around the hollow arm 11 . The sliver is drawn and wound on the roving bobbin 5 through the pressing palm leaf 41, and the number of turns of the roving wound on the pressing palm leaf 41 will affect the tension change an...

Abstract

The invention relates to a twisting mechanism of a semi-worsted roving machine. The twisting mechanism comprises a flyer and a spindle, wherein the top end of the flyer is provided with side holes for sliver passing; the flyer comprises a hollow arm and a solid arm which are symmetrically arranged; a yarn guiding groove is opened on the hollow arm, and extends along the length direction of the hollow arm; the twisting mechanism further comprises a presser mounted at the lower end of the hollow arm; and the top end of the flyer is opened with a notch groove for performing false twisting to sliver. In the twisting mechanism provided by the invention, the notch groove is opened on the top end of the flyer, which exerts a certain friction torque to the sliver while the sliver passes through, so that the sliver is returned around the axis of the sliver to obtain the false twisting, so as to improve the twisting effect, reduce unexpected extending, reduce the end breakage rate, reduce the flying matter, and improve the quality of output yarn.

Description

technical field [0001] The invention relates to a twisting mechanism of a semi-worsted roving frame. Background technique [0002] The roving frame is a spinning machine that makes fiber sliver into roving. Its main function is drafting and twisting, and winding the roving into a certain package to meet the processing requirements of the spinning frame. After the advent of the wing spindle spinning frame at the end of the 18th century, due to the limited draft of the spinning frame, the spun yarn must be spun into roving first, so the roving frame appeared in the early 19th century. This type of roving frame is similar to the flyer spinning frame, which uses a rotary flyer for twisting, and gradually adopts a conical wheel (commonly known as iron) and a manual speed change mechanism to control the winding and variable speed movement of the roving. At the end of the 19th century, the drafting mechanism was still very crude and the drafting capacity was very small. The rovin...
