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 comprises an impregnation wheel set, a first scraper and a second scraper. A plurality of yarn guide grooves are concavely formed in the surface of an impregnation idler wheel, the yarn guide grooves in the lower edge of the impregnation idler wheel are soaked in resin liquid of a resin tank, thefirst scraper is arranged between the impregnation roller and a front guide wheel, the first scraper is provided with a scraper plane, the scraper plane is used for scraping a large amount of resin liquid adhered to the surface of the impregnation idler wheel, the second scraper is arranged between the impregnation idler wheel and the front guide wheel, the second scraper is far away from the resin tank relative to the first scraper, the second scraper is provided with a scraper edge, a plurality of convex parts are convexly arranged on the edge of the scraper, the second scraper is inserted into the yarn guide grooves of the impregnation idler wheel through the convex parts, and the convex parts are used for controlling the resin amounts of the yarn guide grooves with high precision.

Description

technical field [0001] The invention relates to a single-bundle fiber impregnation structure, in particular to a high-speed and high-precision single-bundle fiber impregnation machine for impregnation and gluing with a rated amount of glue. Background technique [0002] Now, a known cloth dipping device mainly includes a yarn feed roller, a yarn outlet roller, a dipping roller and a glue tank, and also includes an adjustable scraping roller and a pressure roller, and the dipping roller is arranged on The upper end of the rubber tank, wherein the rubber dipping roller is externally connected with a power device so that the rubber dipping roller can rotate around the central axis. The distance between the roller and the glue roller and the edge of the dip roller is smaller than the distance between the yarn feed roller and the edge of the glue roller, wherein the glue roller is set on the upper end of the adjustable scraping roller, and the yarn output roller is set on the dip...

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.
