Features: insulation decorative plate coating production line machine configuration profile: Panasonic machine configuration programmable controller (PLC), independent control of the gun in the workpiece by the situation began to paint in order to save the amount of paint. (Optional) automatic gun standard configuration using imported Japanese Iwata .37 caliber gun, spray volume size, angle can be pre-adjusted, each gun individually controlled. Selection gun configuration (optional high-pressure spray gun, air gun or low pressure and medium pressure mixed gas gun), to meet the different efficiency of spray use. An exhaust gas purification system processing machine configuration, to avoid the exhaust gas treated before discharge, the greater the degree of efficiently generated in the painting environment contamination. Conveying speed variable frequency adjustment, suitable for coating requires different speeds. Standard configuration of a large-capacity fuel system of the United States by the diaphragm and the regulator, providing a steady flow for the paint to make paint job is more stable, and more convenient to replace the paint. Different wide lines, through feed inlet means to adjust the limit of its feed position, to prevent the feed deviation phenomenon.
