A cooling device for upper calender rolls

Abstract

This utility model discloses a cooling device for an upper calendering roll, including one or more side air guns. Each side air gun includes an air duct, one end of which is an air inlet connected to a wind control system, and the other end of which is an air outlet pointing towards a corresponding position on the upper calendering roll. The side air gun is mounted on an adjustable bracket, which includes height, forward / backward, and angle adjustments, allowing for adjustments to the height, forward / backward direction, and airflow angle of the side air gun. When installed in the appropriate position, this utility model effectively cools the upper calendering roll, reducing the adhesion of volatiles and other substances, and better preventing glass defects and production hazards caused by roll sticking or wrapping.
