Problems solved by technology

[0006] Among them, the method of spinning fancy yarn with grooves in the rotor is to process the grooves on the fiber sliding surface of the rotor to make them have a certain width and depth, so that the fibers can accumulate in the grooves, and can be processed according to the grooves. The pattern of the grooves can produce certain regular fancy yarns, but the fine details of the fancy yarns spun in this way are not obvious, and because the grooves are prone to dust accumulation, the yarn sliver in the spinning process Increased end-break rate affects the quality of the spun yarn

Embodiment Construction

[0051] The present invention will be further described below in combination with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0052] A kind of rotor cup of the present invention, as figure 1 As shown: it includes a cup body 2 and a cup shaft 1. The cup body 2 is composed of a cup bottom 3 and a cup edge 4. The cup bottom 3 is connected to the cup shaft 1. The back of the cup bottom 3 includes a bottom surface and a On the side, the cup edge 4 circles the cup bottom 3 and intersects to form a condensation groove 6. The bottom surface of the cup...

Abstract

The invention discloses a revolving cup. The revolving cup comprises a cup body and a cup shaft, wherein the cup body consists of a cup bottom and a cup edge; the cup edge and the cup bottom are intersected to form a coagulation groove; the bottom surface of the cup bottom is averagely divided into two halves; one half is provided with at least one narrow seam; a damping block is inlaid in the coagulation groove of the other half along the periphery direction of the cup bottom; and the narrow seams penetrate in the cup bottom. By the revolving cup, the longitudinal linear density of spun yarns is changed in a controlled manner, the tightening twist of a thin portion is great, the fluffy twist of a thick portion is small, and the rule of distribution of thick knots and thin knots conforms to the inlaying law of the open seams and the damping block of the revolving cup.

Description

technical field [0001] The invention belongs to the technical field of spinning equipment, and relates to a rotor, in particular to a slotted rotor. A rotor cup with a damping block embedded in the condensation groove in the circumferential direction of the cup bottom. Background technique [0002] Rotor spinning belongs to the field of open-end spinning. It has the characteristics of high spinning speed, large package capacity, good spinnability and the ability to spin high-quality and low-quality raw materials. It has become the most mature technology and the most widely used spinning technology among new spinning technologies. Wide and economical spinning form. [0003] Rotor spinning can be divided into two types: self-exhausting type and suction type in terms of the cause of the negative pressure in the rotor and the flow direction of the airflow. Among them, the diameter of the rotor used in the self-exhausting rotor spinning machine is relatively large, and there ar...
