The working principle of the infrared heating lamp used in the printing machine is as follows:
Generate infrared: The Infrared heating lamp IR emitter is usually composed of a tungsten filament inserted into an inflated quartz tube. When the current passes through the tungsten filament, the tungsten filament will generate Joule heat due to the resistance and heat the gas in the quartz tube, thereby generating infrared electromagnetic waves.
Emission and radiation: The infrared rays generated radiate outward from the industrial infrared heat lamp, and its propagation speed is extremely fast, and it can penetrate the air and directly act on the surface of the object that needs to be heated in the printing machine, such as the printed cloth, paper, etc., without causing a large amount of heat to the surrounding air, thereby reducing energy loss and improving heating efficiency.
Absorption by the heated object: When infrared rays radiate to the surface of the object, it will cause the molecules and atoms inside the object to resonate. Because different substances have different absorption wavelengths of infrared rays, the wavelength of the infrared heating replacement halogen lamp selected by the printing machine generally matches the wavelength absorbed by the heated material, so that the heated object can absorb a large amount of infrared rays, thereby intensifying the molecular movement inside the object, increasing the vibration frequency, and the temperature of the object will also increase accordingly, thereby achieving the purpose of heating. For example, in a digital direct-injection printer, after the ink is sprayed onto the fabric, the infrared lamp heating lamp halogen bulb irradiates the fabric surface to quickly dry and solidify the ink, thus improving the quality and efficiency of printing.
Temperature control and adjustment: The Infrared lamp industrial infrared heat lamp in the printing machine can generally be adjusted as needed. By changing the current or heating time, the infrared radiation intensity and heating temperature can be controlled to meet the heating temperature requirements of different printing processes and materials, ensuring the consistency and stability of the printing effect.
