Novel prepreg presoaking device

Abstract

The invention discloses a novel prepreg presoaking device. The novel prepreg presoaking device comprises a glue tank and a conveying roller, wherein the conveying roller comprises a presoaking rollerarranged inside the glue tank and a first transmission roller arranged above the glue tank; at least two glue scraping rollers are arranged between the first transmission roller and the presoaking roller, and the glue scraping rollers are arranged on two sides of the transmission direction respectively so as to scrape glue on positive and negative surfaces; a scraper blade is arranged on each gluescraping roller, each glue scraping roller is connected with a driving device so as to drive the corresponding glue scraping roller to rotate actively; and simultaneously, the rotation directions ofthe glue scraping rollers are opposite to the transmissions of the glue scraping rollers. In the device, glass fabric is conveyed by a conveying roller, the glass fabric is guided into the glue tank for glue soaking by the presoaking roller, after glue soaking of the glass fabric, the glue scraping rollers rotate actively, the scraper blades are driven to scrape a glue solution on the glass fabric, simultaneously, the glue scraping is more uniform due to the arrangement of the scraper blades, and simultaneously, foreign matters such as broken filaments on the glass fabric can be scraped.

Description

technical field [0001] The invention relates to a prepreg processing device in the copper clad laminate industry, in particular to a prepreg prepreg device. Background technique [0002] In the processing of prepreg, the glass fiber cloth is impregnated by the prepreg device first, and then enters the main dipping system for processing to form a prepreg. During the production process of the prepreg, due to the short immersion time, the glue solution penetrates unevenly, and there is still a large amount of glue solution unevenly on the surface of the glass fiber cloth after the glue is scraped, which is shown as alternating along the longitudinal direction of the glass fiber cloth. The presence of streaks which cannot be repaired after the main dip. Moreover, it is easy to accumulate glue on the squeegee rod. If the glue hangs for too long to make the solid content increase to a certain extent and then drips and adheres to the glass fiber cloth, it will form a piece on the ...

[0002] In the processing of prepreg, the glass fiber cloth is impregnated by the prepreg device first, and then enters the main dipping system for processing to form a prepreg.

The presence of streaks that cannot be repaired after the main dip

Moreover, it is easy to accumulate glue on the squeegee rod. If the glue hangs for too long to make the solid content increase to a certain extent and then drips and adheres to the glass fiber cloth, it will form a piece on the thin prepreg with a darker color than other glues. area and thicker than other bad areas
