The strands complete the accumulation process in the airflow guiding device. The airflow guiding device is optimized and modified to increase the stress during the movement of the strands and guide the strands Standardize the accumulation, improve the control of the strands, improve the evenness of the strands, and reduce the spinning triangle to a greater extent, thereby further reducing harmful hairiness.

Contents of the invention

The purpose of this utility model is to provide an airflow guiding device with an arc-shaped air intake channel, by adopting an airflow guiding piece with a certain thickness, and the upper surface of the guiding piece is provided with upper arcs arranged at equal intervals. There are lower arc-shaped grooves arranged at equal intervals on the lower surface, and arc-shaped passages are used to connect the upper and lower arc-shaped grooves, so that negative pressure enters through the upper arc-shaped grooves, arc-shaped passages and lower arc-shaped grooves When entering the gathering area, a clockwise or counterclockwise vortex flow is generated, and then a weak twisting effect is produced on the fiber strands in the gathering area, which plays a role of weak twisting while generating the gathering effect, and improves the yarn quality.

In order to achieve the above object, the technical solution adopted by the utility model is: an airflow guiding device with an arc-shaped air intake passage, including an upwardly embedded pin and an airflow guide piece, the upwardly embedded pin is an arc-shaped structure, including a left arc Shaped upward embedded pin and right arc upward embedded pin, the left arc upward embedded pin and right arc upward embedded pin are respectively fixed on the left and right sides above the airflow guide plate, respectively on the left and right sides below the airflow guide plate A left support pin and a right support pin are installed, and the airflow guide piece is a cuboid structure, and the front side, rear side, left side, right side, upper side and lower side of the airflow guide piece are arc-shaped surface, the upper side and the lower side are both concave arc-shaped surfaces, the thickness of the airflow guide is between 4-6mm, and the upper surface of the airflow guide in the accumulation area is provided with equal intervals The first upper arc-shaped grooves with an inward concave structure or an inward convex structure are arranged, and the first lower arc-shaped grooves with an inward concave structure or an inward convex structure are arranged at equal intervals on the lower surface, and the first The upper arc-shaped groove and the first lower arc-shaped groove are connected by a first arc-shaped channel with an inward concave structure or an inward convex structure, and the airflow guide fins are arranged at equal intervals on the left side of the gathering area. The second upper arc-shaped groove with an inward convex structure or an inward concave structure has a second lower arc-shaped groove with an inward convex structure or an inward concave structure arranged at equal intervals on the right side, and the second The upper arc-shaped groove and the second lower arc-shaped groove are connected by a second arc-shaped passage having an inwardly convex structure or an inwardly concave structure.

When in use, first fix the airflow guiding device on the top roller frame through the left and right arc-shaped upward embedded pins. During spinning, the airflow guiding device is pressed on the hollow front roller, wherein the left support pin and the right support pin are in contact with the front roller. The negative pressure generated in the hollow front roller enters the accumulation area through the first upper arc-shaped groove, the first arc-shaped passage and the first lower arc-shaped groove, and then passes through the second lower arc-shaped groove, the second arc-shaped passage and the second The upper arc-shaped groove flows out, and then generates a clockwise or counterclockwise vortex flow in the accumulation area, and then produces a weak twist accumulation effect on the fiber strands in the accumulation area, and plays a weak twisting effect while generating accumulation , Improve yarn quality.
