Flexible substrate surface coating preheating and cooling system

Abstract

This invention provides a preheating and cooling system for surface coating of flexible substrate, comprising: a feeding wheel for fixing untreated flexible substrate; a receiving wheel for pulling and stacking the surface-treated flexible substrate; a first guide wheel located downstream of the feeding wheel, which allows the flexible substrate to abut against the surface and changes the conveying direction of the flexible substrate, and the first guide wheel collectively defines a heating path; a heating unit disposed between the heating paths, which heats the flexible substrate; a main heating wheel located downstream of the first guide wheel, which allows the flexible substrate to be bonded and wound around the substrate, and which heats the flexible substrate; a second guide wheel located downstream of the main heating wheel and upstream of the receiving wheel, which allows the flexible substrate to abut against the surface and changes the conveying direction of the flexible substrate, and the second guide wheel collectively defines a cooling path; and a cooling unit disposed between the cooling paths, which cools the flexible substrate.

Claims
