Technical Field

The invention relates to the field of textile machinery equipment, in particular to a yarn joint element.

Background

In the textile field, the joint quality of the yarn directly affects the production efficiency and the cloth cover quality of the next process, so the joint quality of the yarn is a key technology in the technical field of yarn winding. In a yarn winding apparatus, when a yarn defect on a yarn is removed or a cop is replaced, a bobbin suction nozzle and a cop suction nozzle feed the yarn on the bobbin and the cop to a yarn processing device and a yarn splicing member fed to the yarn processing device, respectively. Two yarns are untwisted in a yarn preparation element of the yarn processing device under the action of air flow, and then the two yarns are twisted together under the action of air flow in a joint element.

There are two types of yarn splicing elements in the past, one of which must use a cover to ensure that the yarn does not escape from the yarn path under the action of the air flow. The drawback of such a joint element is that the cover is subject to wear and the mechanical mechanism in which the cover is located is complex and prone to lint. The yarn connector also has a connector element, a cover is not used, but the center lines of the two air flow channels pass through the center line of the yarn channel, so that air flow is not easy to form cyclone after entering the yarn channel, and the quality of the yarn connector is not influenced.

The technical scheme of the invention is as follows:

a yarn joint element comprises a yarn channel I and a yarn channel II, wherein the yarn channel I and the yarn channel II are respectively positioned at two sides of the joint element and do not penetrate through the joint element, and parts of the yarn channel I and the yarn channel II are crossed and overlapped to form a yarn guide-in channel; the upper sides of the first yarn channel and the second yarn channel are respectively a first slope-shaped yarn leading-in surface and a second slope-shaped yarn leading-in surface; the lower parts of the first yarn channel and the second yarn channel are provided with airflow inlet openings which are communicated with the first yarn channel and the second yarn channel through the first airflow channel and the second airflow channel on the left side and the right side; yarn blocking plates are arranged on the left side and the right side of the first yarn channel and the second yarn channel and are in sliding connection with the yarn joint elements.

Furthermore, the central line of the yarn channel I of the air channel-connecting channel is staggered with the central line of the yarn channel I of the yarn channel III; the central line II of the yarn channel II of the second communicating channel of the airflow channel is staggered with the central line IV of the yarn channel II (4 b).

Furthermore, an elliptical hole is formed in the yarn blocking plate, a fastening screw is arranged on the yarn joint element, the elliptical hole slides left and right under the limit of the fastening screw, and the yarn blocking plate can be fastened to a proper position.

The invention achieves the following beneficial effects:

the yarn joint element provided by the invention does not use a cover, and in order to enable air flow to easily form cyclone after entering the yarn channel, the central lines of the two air flow channels are designed to be at the positions which are deviated from the central line of the yarn channel. The main air supply port is arranged at the bottom, and then the main air supply port is divided into two paths, enters the airflow channel and then enters the yarn channel. The yarn joint element provided by the invention is provided with the yarn blocking plate, the position of the yarn blocking plate is adjustable, and the size of the outlet of the yarn channel can be controlled according to the joint requirement of the yarn.
