AI Technical Summary

Technical Problem

When the membrane is heated by the hot air system, the membrane thickness is prone to change, and thinner areas are more easily damaged, resulting in uneven forming and low yield.

Method used

The drying and forming device is equipped with alternating rotating cooling cylinders and drying mechanisms. Differentiated heat dissipation effects are used to dry film segments of different thicknesses in different areas, avoiding excessive heating and damage to thin-walled areas and ensuring that thick-walled areas are fully dried.

Benefits of technology

It improves the uniformity of membrane material drying and forming and the yield, and solves the problem of poor adaptability of traditional equipment to changes in membrane thickness.

Abstract

The application relates to the technical field of film drying, and discloses a drying and forming device for films, which comprises a shell, two groups of cooling cylinders are rotatably installed in the opposite inner walls of the shell, rotary joints are installed at the two ends of the two groups of cooling cylinders, connecting pipes are installed on the sides, away from the corresponding cooling cylinders, of each rotary joint, and the two cooling cylinders are staggeredly arranged, the two groups of staggeredly rotating cooling cylinders are arranged in the shell, drying mechanisms are arranged on the two sides of the corresponding cooling cylinders, and the film material can be subjected to regional and adjustable drying treatment during movement; when the film passes through the staggeredly arranged cooling cylinders, film sections with different thicknesses can obtain differential heat dissipation effects due to the difference in contact area with the cooling cylinders; in cooperation with the drying mechanisms, the thin-wall region can be prevented from being damaged due to excessive heating, and the thick-wall region can be ensured to be fully dried, so that the uniformity and yield of film material drying and forming are improved, and the problem of poor adaptability of traditional devices to film thickness changes is effectively solved.
