Embodiment Construction

[0013] The specific implementation manner of the present utility model is described in further detail below.

[0014] like figure 1 As shown, a pipe elbow false twister of the present invention includes a cylindrical drum 2 and an elbow 1 located inside the drum 2, and the inlet 5 and the outlet 6 provided on the elbow 1 are respectively located at both ends of the drum 2. , the elbow 1 is provided with three bends 3, and the elbow 1 is fixedly connected to the inner wall of the drum 2 at the bend 3. The cross section of the pipe 1 is circular, and the inlet 5 and the outlet 6 are trumpet-shaped openings; the wall of the elbow 1 is also provided with an air inlet 4, and the air inlet 4 cuts into the wall of the elbow obliquely or vertically, and points to the wall of the elbow. One end of the outlet of the tube 1 and one end of the air inlet 4 are located outside the drum 2 .

[0015] In one embodiment of the present utility model, a driving device of the elbow false twister...

Abstract

The invention discloses a curved pipe false twister, which comprises: a curved pipe and a rotating cylinder, characterized in that the rotating cylinder is fixedly connected to the inner wall of the curved pipe, the cross section of the curved pipe is circular, and at least one Bending, one end of the elbow is provided with an inlet, and the other end is provided with an outlet, the inlet is located at one end of the drum, and the outlet is located at the other end of the drum. The curved tube false twister of the present invention is equipped with a curved tube bent multiple times, which can gently hold the yarn in each small partial section, reduce yarn damage, and increase the grip of the false twister on the yarn at the same time The holding length of the yarn is relatively large as a whole, and the false twisting efficiency can be increased. The structure of the present invention is simple and universal, and can be used in active false twisting and passive false twisting devices.

Description

technical field [0001] The utility model belongs to the field of chemical fiber spinning, in particular to an elbow false twister. Background technique [0002] In the textile industry, false twisting is a special processing technology, both ends of the yarn are controlled, twisting between the two ends, the same number of twists can be produced on the sliver, but the twist direction is opposite, and finally the overall The twist added to the yarn is zero. On the roving frame, the strength of the same section as the designed twist direction of the sliver (that is, the strength of the roving spinning section) can be increased, but the other section (the roving winding section) produces untwisting; After heat-setting a section of temporarily twisted silk yarn, the two ends are merged and untwisted to keep the overall twist at zero. In the prior art, the structure of the false twisting device is relatively complicated. One type is better in gripping the yarn, but wears the yar...
