Abstract
Description
technical field
[0001] The invention belongs to the technical field of laser holographic product production equipment, and relates to a coating machine, in particular to an energy-saving device for heat recovery and utilization of the coating machine. Background technique
[0002] During the production process of the laser holographic film, an information layer must be coated on the PET film, and the information layer is composed of about 20% resin and about 80% solvent. In order to dry and solidify the information layer, it must be processed after coating. A drying tunnel about 15 meters long is used for drying. The drying tunnel is divided into five sections, and the heating temperature of the five-section oven is 90°C, 110°C, 135°C, 145°C, and 90°C. Each oven is sent fresh air into the electric heater by a blower fan with an exhaust air volume of 2000 cubic meters per hour, and the hot air heated to the above temperature in the electric heater is sent into the oven to dr...
