AI Technical Summary
The prior art cannot perform adaptive limit treatment for cloth of different widths, resulting in adverse phenomena such as slip edge curling at the edges of the cloth during the winding process.
A polypropylene pad winding mechanism including a base frame, a reel, an adapter and a scraper mechanism is designed. The adapter mechanism adjusts the spacing between the limit discs on both sides of the reel through pre-installed grooves and adjustment components, and the scraping mechanism smoothes and scrapes the cloth through the motor-driven screw and the continuous carriage.
By adjusting the spacing of the limit plate and adjusting the spacing of the scraper, it can effectively avoid the slip edge rolling of the edges of the cloth during the winding process, ensuring the quality of the winding.
