Yarn swinging plate for producing nonwoven fabric

Abstract

The invention discloses a yarn swinging plate for producing a nonwoven fabric, and belongs to the field of nonwoven fabric machinery. The yarn swinging plate comprises a bottom plate and a swinging plate, wherein the bottom plate is fixedly arranged on a swinging arm; the swinging plate is fixedly arranged on the bottom plate through bolts; a groove is formed in the surface, contacting with yarns, of the swinging plate; a yarn swinging block is arranged in the groove; tows are sprayed onto the yarn swinging block through an airflow drafting tube; the swinging plate is made from a glass material, a spiral metal coil is sealed in the swinging plate, a conductive plate is connected in series with the spiral metal coil, positive and negative leads of the spiral metal coil extend out of the swinging plate, and are connected in parallel with a power supply and a connecting indicator lamp. According to the yarn swinging plate, the yarn swinging block made from a strong-strength and abrasion-proof material is arranged in the groove to solve the problem that the yarn swinging plate is abraded or ruptured by the continuous high-speed spraying of the fiber tows onto the yarn swinging plate, reduce the abrasion or the ruptures of the yarn swinging plate and strengthen the strength of a spraying point; an alarming device is arranged, so that the influence of separation of the yarn swinging block on the quality of the product is reduced.

Description

technical field [0001] The invention relates to a spinning plate used in the manufacture of non-woven fabrics, which belongs to the field of non-woven fabric machinery. Background technique [0002] In the non-woven fabric manufacturing process, after the tow is sprayed out through the air drafting tube, it enters a device for dispersing the tow under the air drafting tube, so that the fiber filaments are scattered and fall on the laminating machine to form fibers The net is then further needle-punched and rolled into a non-woven fabric. At present, most of the yarn swinging devices are used, including a swinging swinging plate and a bottom plate for fixing the swinging plate, and the bottom plate is fixed on the action device. The existing problem is that the ejected tow hits the swinging plate, the speed is extremely high and the If the hitting position is the same, the pendulum plate is easy to wear or break. If it is not replaced in time, it will affect the produc...

AI Technical Summary

Problems solved by technology

At present, most of the yarn swing devices are used, including a swinging swing plate and a bottom plate that fixes the swing plate, and the bottom plate is fixed on the action device. The problem that exists is that the ejected tow hits the swing plate, and the speed is extremely high and The striking position is the same, the pendulum plate is easy to wear or break, and if it is not replaced in time, it will affect the product quality, and if it is replaced frequently, it will affect the production efficiency
