Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] The appearance of the concentrator is tubular, and the contour line of the section at the entrance is composed of arc R1, line segment a, and arc R2. The contour line of the cross-section at the exit is composed of circular arc R3, line segment b, and circular arc R4, which are smoothly and seamlessly connected. The length of the collector is 2 mm in thickness. The radius of the arcs R1, R2 is 5 mm, and the radius of the arcs R3, R4 is 2.5 mm. The inclination angles α and β are 8°, and the total length h is 1.5 mm. Spun yarn collectors are different from traditional collectors in terms of shape, size and quality. The section shape of the collector is similar to a circle, and the radian of the contact between the collector and the surface of the top roller is appropriately increased, and the two-point contact of the original collector is changed to a circular arc c...

Abstract

The invention discloses a spun yarn collector. The section of the spun yarn collector is similarly circular, the radius of a contact arc of the collector and the surface of a roller is properly increased, and a double-point contact mode of the original collector is replaced by an arc contact mode, so that the problem of high friction factor due to obvious corner angles of the traditional collector is solved, sliver squeezing frequency of the inner wall of the collector is reduced, the yarn quality is improved, the width of each sliver is effectively reduced, spinning triangular space is reduced, the slivers are compact in structure and smooth in appearance, hairiness is reduced, and the yarn strength is improved. Compared with the traditional collector, the spun yarn collector has the advantages that the width of an outlet of the collector is reduced, and sliver collecting and finishing effects are good on the premise that the yarn quality is guaranteed.

Description

technical field [0001] The invention relates to a spinning device in the field of textiles, in particular to a collector used for spun yarns in a textile machine. Background technique [0002] Although the concentrator on the spinning frame is small, its function is not small. It can reduce the width of the fiber strands, sort out the floating fibers, reduce fly and the cots and piles produced by the electrostatic adsorption of the drafting cots. , reduce raw material consumption, significantly reduce yarn hairiness, and improve yarn quality. The application of the new collector is more conducive to improving the yarn quality. At present, the shape of the entrance of the common spun yarn collector is approximately rectangular. When the yarn passes through the collector, the collector squeezes the yarn, and the inner wall of the collector rubs against the yarn, which affects the yarn quality. The traditional collector is made of plastic material that continuously rubs again...
