AI Technical Summary
Traditional PVC film shaping mechanisms are cumbersome and time-consuming to adjust the distance between the pressure roller and the cooling roller, making it difficult to adapt to the production needs of films of different thicknesses. Furthermore, the film is prone to stretching deformation or breakage due to sudden tension changes during high-speed production, affecting production efficiency and finished product quality.
The design employs a ratchet and pawl adjustment mechanism and a buffer mechanism. The pawl and ratchet engage to achieve rapid and precise adjustment of the distance between the pressure roller and the cooling roller. The elastic element absorbs the instantaneous tension fluctuations of the film during the traction process, ensuring the flatness and stability of the film.
It enables rapid and precise adjustment of the gap between the pressure roller and the cooling roller, improving production efficiency and equipment adaptability, reducing film stretching deformation and breakage, and improving the stability of finished product quality. It is especially suitable for high-speed continuous production.
