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

[0050] 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.

[0051] 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 around the cup bottom 3 and intersects to form a concave condensation groove 6. On the bottom ...

Abstract

The invention discloses a rotary cup which comprises a cup body and a cup shaft, wherein the cup body is composed of a cup bottom and a cup edge; the cup edge and the cup bottom are crossed and formed into a condensation slot; at least two narrow seams are uniformly arranged on the periphery of the bottom surface of the cup bottom; a damping block is embedded into the condensation slot along the peripheral direction of the cup bottom; the narrow seams pass through the cup body. A yarn which is spun by utilizing the rotary cup provided by the invention is in a special style of controllable change in longitudinal yarn density, a tight and high-twist thin part and a fluffy and low-twist rough part. The appearing law of the rough thin sections is consistent with the embedding the law of the seams and the damping block of the rotary 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, in particular to a rotor with symmetrical gaps on the body of the rotor, which are condensed along the circumferential direction of the bottom of the rotor. A rotor cup with a damping block embedded in the slot. 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...
