The automatic reciprocating spray painting robotic arm equipment for large die-casting parts consists of a dry spray painting room, an automatic spray painting system, a paint mixing room, etc.
1. Dry spraying room:It consists of a room body, air supply system, exhaust system, exhaust gas treatment system, lighting system, electrical control system, combustible gas detection and alarm device, video surveillance device, electrostatic discharge device and other structures.
The dry spraying room adopts an upper air supply and side exhaust method, which ensures the cleanliness of the dry spraying room. Compared with the upper air supply and lower exhaust method, the air volume is reduced, which can save more than 30% of energy.
Exhaust gas treatment: dry filter+UV photolysis+activated carbon adsorption+high exhaust chimney above 15m, exhaust gas emissions comply with GB16297-1996 "Comprehensive Emission Standards for Air Pollutants"
Air supply filtration: blinds → wet curtains → dry curtains → primary filter cotton → G4 primary filter → F8 medium efficiency bag filter

2. Automatic spraying system:Automatic spraying device (four axis)Spray reciprocating machine）The structure consists of a rotating car for conveying parts, a paint supply and spraying system (spray gun, diaphragm pump), an electrical control system, etc.
The automatic spraying system adopts a four axis reciprocating machine, which sprays on the side and uses side exhaust for ventilation. The reciprocating machine has less pollution and is easy and fast to maintain and repair. It has intelligent programming function, and the spraying program can be automatically generated by inputting the product diameter, product length, and spraying times. The spraying method can be either step-by-step or continuous, and can be chosen freely. Left and right travel of 11000MM, rack bearing capacity of 10KG, speed range of 0-1.5m/s, reciprocating positioning accuracy of ± 2MM.

3. Paint mixing room:It consists of a room body, exhaust system, lighting system, combustible gas detection and alarm device, electrical control room and other structures.
The paint mixing room adopts a ventilation method of natural air intake and mechanical exhaust. The fresh air supplement outlet is equipped with air filter cotton and inlet louvers, and the exhaust system is sharedDry spraying roomThe exhaust and exhaust gas treatment system has an exhaust volume that meets a ventilation rate of 100 times per hour. Designed according to fire and explosion prevention requirements, it is safe, energy-saving, and easy to maintain and replace.
