Anti-yarn-winding device

Abstract

The invention discloses an anti-yarn-winding device comprising a main horn-shaped horn mouth body; a separation board arranged inside the main horn-shaped horn mouth body divides the main horn-shaped horn mouth body into two parts; and a leading-in end is arranged above the main horn-shaped horn mouth body and a leading-out end is arranged below the main horn-shaped horn mouth body. A vertical yarn slot is formed in the top front end of the front side of the main horn-shaped horn mouth body, wherein the length of the yarn slot is the half of the overall length of the main horn-shaped horn mouth body. An inclined cutting surface is processed at the leading-out end; the separation board extends to the three-quarter part from the middle of the inside of the main horn-shaped horn mouth body from top to bottom and forms, together with the inclined cutting surface, an observation port. Using the anti-yarn-winding device, a phenomenon that a rough yarn is broken in a yarn slot because of twisting spinning due to winding of the rough yarn at the leading-out end can be avoided. With the reserved observation port, the feed-in situation of the yarn at the observation port can be observed through the observation port and thus the quality situation of the yarn can be determined preliminarily in advance according to the yarn parallel situation based on observation, so that the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a yarn anti-winding device used on a spinning machine. Background technique [0002] In the spinning process, during the twisting process of the yarn from the spool to the roller, the yarn needs to be introduced into the roller through a bell-shaped device. The front side of the existing yarn bell is provided with a top-to-bottom penetrating The yarn groove of the main body of the bell mouth, the disadvantage of this type of design is that the yarn is prone to breakage in the yarn groove. Moreover, the existing yarn bell mouth is a closed design, and it is impossible to observe the yarn in the bell mouth. The internal winding situation cannot preliminarily determine the quality of the yarn. If there is a quality problem with the yarn, it can only be found in the subsequent process, which causes a certain waste of resources in production. In view of the above, how to im...
