Description

Technical Field

[0001] The utility model relates to the technical field of nonwoven fabrics, in particular to a positioning tool. Background Art

[0002] In the nonwoven fabric production line, the electrostatic gun is a very important equipment in the tubular drafting device. Its equipment structure and installation accuracy have a great influence on the dispersion of the yarn bundles, and thus affect the uniformity of the product fabric surface. Among the factors affecting the installation accuracy of the electrostatic gun, the distance from the electrostatic gun duckbill to the oblique baffle of the electrostatic gun and the distance from the lower end of the organic board to the oblique baffle of the electrostatic gun have the greatest influence on the dispersion of the yarn bundles. The distance from the electrostatic gun power supply seat to the adjacent swing plate and the distance from the electrostatic gun oblique baffle to the adjacent swing plate connecting rod have the greatest influence on the dispersion width of the yarn bundle. The prior art, such as patent announcement number CN 105803675 A, discloses an electrostatic wire separation adjustment device for two-component tubular drafting. The present invention mainly installs an adjustment component on the existing tubular drafting device that can move the electrostatic gun in the width direction. In the prior art, the distance from the electrostatic gun power supply seat to the adjacent swing plate and the distance from the electrostatic gun oblique baffle to the adjacent swing plate connecting rod are used to adjust the distance, and the adjustment process is also measured with a steel ruler. During the assembly of the electrostatic gun, the distance from the electrostatic gun duckbill to the oblique baffle of the electrostatic gun and the distance from the glass sheet at the bottom of the organic board to the oblique baffle of the electrostatic gun are also measured with a steel ruler. The disadvantage is that the distance is measured with a steel ruler, which results in errors caused by the observation angle and human vision, thus affecting the installation accuracy of the electrostatic gun and affecting the uniformity of the product surface.
