Problems solved by technology

At present, in order to make full use of resources and reduce production costs, textile mills often use the leftovers of chemical fiber factories, that is, small and short chemical fiber materials, as raw materials. Short, the difficulty of spinning increases when the conventional twist-stop is used. In addition, the raw material of this kind of chemical fiber has a high oil content, and there is a lot of oil residue when rubbing against the twist-stop. Low, poor sliver shape, poor spinning quality

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 , figure 2 As shown, the twist resistance head of the present invention includes a body 3, the body 3 is a steel body with a longitudinal section of "T" shape, the center of the body 3 is provided with a through hole 4 connecting the upper end surface and the lower end surface of the body 3, the through hole 4 The upper part of the body is a circular arc bell mouth with a large top and a small bottom, and the bottom of the through hole 4 is a straight bell mouth with a small top and a large bottom. The upper end surface of the body 3 is provided with a circular boss 2 coaxial with the through hole 4, The outer diameter of the circular boss 2 is smaller than the outer diameter of the upper end surface of the body 3, and the upper end of the through hole 4 extends to the upper end surface of the circular boss 2...

Abstract

The invention relates to a twisting prevention head which comprises a main body (3); a through hole (4) communicated with the upper end face and the lower end face of the main body (3) is arranged at the center of the main body (3); a round lug boss (2) coaxial with the through hole (4) is arranged on the upper surface of the main body (3); the outer diameter of the round lug boss (2) is smaller than the outer diameter of the upper end face of the main body (3); the through hole (4) extends to the upper end face of the round lug boss (2); and a circularly arced bellmouth tapering downwards is arranged at the upper part of the through hole (4). With the twisting prevention head, the probability of breakage of a sliver is lower, the spinning efficiency is higher and the spinning quality is better.

Description

technical field [0001] The invention relates to the technical field of air spinning, in particular to an anti-twisting head for a rotor spinning machine. Background technique [0002] At present, spinning technology mainly includes rotor spinning and ring spinning. Rotor spinning is through the high-speed rotating rotor and the negative pressure in the cup to complete fiber transportation, cohesion, and twisting into yarn. Compared with ring spinning, spinning has the characteristics of short technological process, large package capacity, high output and high labor productivity, and is the most widely used spinning technology at home and abroad. [0003] On the rotor spinning machine, the main purpose of using the twist navel is to make the yarn arm section (that is, the yarn from the navel to the rotor coagulation groove) The twist on the strip) increases, which can increase the connection force between the yarn arm section and the strip, and reduce the breakage. At prese...
