通入冷却水的辊筒称为冷却辊。 用途1：压延薄膜或胶黏带涂布时，在成品成卷时为了减少热材料冷却时收缩引起的变形，在成卷前 将材料 通过冷却辊使其降温来达到减少材料的变形。 用途2：冷却辊位于卷筒纸干燥装置后边的辊子，用于将卷筒纸的温度降低到热固型油墨的固化温度 上。 用途3：镭射模压机上的冷却推力辊及UV冷却辊。 冷却辊分类：内管冷却、螺旋及双螺旋冷却。
Cooling roller:
Cooling water is injected into the roller called cooling roller.
Uses: calendered film or adhesive tape coating, refined into a roll in order to reduce the thermal cooling shrinkage caused
by the deformation, in rolls of materialThe deformation of the material is reduced by cooling the cooling roller.
Uses: cooling rollers located behind the web drying device roller for would reduce the temperature of the web to the curing
temperature of the thermosetting ink.
Uses: cooling thrust roller and the cooling roller UV laser molding machine.
Cooling roll classification: internal cooling, screw and double screw cooling.
