 一、Flow drawing
二、Legend 1. Unreeling Machine The aluminum roll is imposed with certain tension under the function of the magnetic powder arrester. Then drawn by the driving machine, the aluminum roll is unreeled and transported for exercise. Use the splicer platform to connect the heads of relative aluminum reels by leveling it up.
3.1 Degrease slot Use the alkalescence degrease produced by General Motors of the United States to remove the oil dots and the loose oxide on the surface of the aluminum roll, having no pollution to the environment. 3.2 Brush slot Clear away the stubborn oil dots and impurity remained on the surface of the aluminum roll.
3.3 Wash Tank Wash clean the aluminum roll degreased and clean most of the water on its surface. When the aluminum roll is moving forward along the product line after being washed, use the well mixed non-chrome chemical disposal to equally spread and form a film on the face and back of the aluminum roll to make up the surface full of tiny hole like a bee nest. The clinging intensity of the film after this coating should be guaranteed. There should be no pollution to the environment. Dry the drug fluid on the surface of the aluminum up. Blow the heated aluminum roll cold. Draw the aluminum at a uniform speed. The D.C. motor is to control the driving so as to ensure that running is stable with an equal speed and to ensure the rewinding tension. Tidy up the chemical aluminum roll. The auto controll D.C. motor can always keep the rewinding tension unchanged.
