High-speed and high-precision single-bundle fiber impregnation machine

Abstract

The invention provides a high-speed and high-precision single-bundle fiber impregnation machine, which includes: an impregnation wheel set is concavely provided with a plurality of yarn guide grooves on the surface of the impregnation roller, and the yarn guide grooves at the lower edge of the impregnation roller are soaked in the resin tank In the resin liquid, a first scraper is arranged between the impregnation roller and the front guide wheel, and the first scraper is formed with a scraper plane, and the scraper plane is used to scrape off a large amount of resin adhering to the surface of the impregnation roller liquid, a second scraper is arranged between the impregnation roller and the front guide wheel, and the second scraper is farther away from the resin tank than the first scraper, and the second scraper is formed with a scraper edge, and the scraper edge A plurality of convex parts are protruded, and the second scraper is inserted into the yarn guide groove of the impregnating roller with the convex part, and the convex part is used to control the resin amount of the yarn guide groove with high precision.

Description

technical field [0001] The invention relates to a single-bundle fiber dipping structure, in particular to a high-speed and high-precision single-bundle fiber impregnation machine for impregnation and gluing with a rated glue amount. Background technique [0002] Today, a cloth dipping device is known, which mainly includes a yarn feeding roller, a yarn outputting roller, a dipping roller and a glue tank, and also includes an adjustable squeegee roller and a gluing roller, and the dipping roller is arranged on the The upper end of the glue tank, where the external power device of the dipping roller enables the dipping roller to rotate around the central axis, the yarn feeding roller, the adjustable rubber squeegee roller and the gluing roller are arranged on one side of the rubber dipping roller, wherein the adjustable rubber squeegee The distance between the roller and the rubber roller and the edge of the dipping roller is smaller than the distance between the yarn feed rol...

AI Technical Summary

Problems solved by technology

Looking at the above-mentioned known structures in detail, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: the temperature difference between the arrangement and the glue is too large, and the temperature of the glue will drop rapidly when they are in contact with each other, which will affect the fluidity of the glue. and adhesion, resulting in insufficient dipping amount and the inability to increase the speed of gluing. On the other hand, although the adjustable scraping roller can scrape the dipping roller, due to the high viscosity of the glue itself, in fact, when the yarn feeds When the speed or the speed of the dipping roller is close to 30 m / min, the glue will form a huge resistance to the adjustable squeegee roller, so it will form a wavy overflow of glue (the adjustable squeegee roller jumps), resulting in uneven glue application and The technical problem that the processing speed cannot be improved. Furthermore, when the glue contacts the arrangement and leaves the dipping roller, it will immediately cool down, so that the glue is only soaked on the surface of the arrangement, and there is no dipping inside the arrangement, thereby reducing its dipping quality.
