The GRACO Merkur bellows plunger pump has a 24:1 pressure ratio and a 9L flow rate. It can quickly switch and recover, is easy to rinse for color changes, and produces minimal pulsing to ensure an even spray.
The high-resolution, high-accuracy grating U.S. Bonner light curtain with solenoid valves automatically detects products, controls the spray range, and switches the spray guns.
The two spray painting axes are independently driven by two servo motors and centrally controlled by a PLC system, ensuring accurate spray motion and precise speed adjustment.
Two opposing spray axes reciprocate for even painting of moving products. The HIWIN silent linear guide rail features an ISHAN automatic lubrication device that injects fresh lubricant and removes waste, ensuring optimal rail performance.
The PE belt features high tensile strength, excellent winding, oil resistance, and easy cleaning. Equipped with an automatic correction device and an internal scraper, it ensures stable long-term operation and lasting double-sided cleanliness.
At the exit of the spray booth, the automatic belt-cleaning trolley scrapes off excess paint for recycling, then pumps thinner on the stainless steel rollers to wash the running belt in two stages, ensuring it is clean and dry during work.
Large fan and filter supply ample fresh air from the spray booth top, forming a pressurized airflow to reduce paint mist and collect paint in the back box for recycling and multiple filtration; all filter layers are easily removable for cleaning or replacement.
