1. The operator should understand the structure, performance, principle, and operating procedures of the coating line before they can be employed.

 

2. Prepare the preparation before painting and start the heating device; when the temperature rises to the set temperature, start the conveyor to start the fan and open the conveying lubrication device.

 

3. Before use, check that all parts have no problem before use; check the fasteners and tightening of the catenary regularly, and clean the rack regularly.

 

4. When starting the conveyor, the speed regulation should be smooth, the chain speed should be gradually increased from low, and the chain speed should be adjusted to zero when shutting down, so as to avoid the sudden start-up damage to the rectifier components.

 

5. The hanging workpiece should be firm and stable, and the workpiece size specified by the catenary should not be exceeded (the workpiece diagonal angle ≤ 1m); the workpiece quality that cannot be passed over the catenary is ≤ 50kg; the wire speed specified by the catenary cannot exceed 1.5m.

 

6. Select the set temperature and line speed according to the thickness of the workpiece; the thicker the workpiece, the higher the temperature and the slower the chain speed.

 

7. The paint temperature is set at 130-140 ° C, the temperature is 30-40 minutes, the spray temperature is set at 190-200 ° C, and the temperature is 15-20 minutes.

 

8. The workpiece enters the front wall of the water curtain spray booth and is evenly coated with butter. Add the curing agent to the water, then turn on the water pump, fan and lighting in turn, and start spraying when the workpiece is fed. Clean the wall of the chamber and remove the paint in the sink before leaving work. Clean the water pump filter in time and turn off the power and air supply.

 

9. The thickness of the water curtain in the spray booth should be ≥ 2mm and uniform. The water level of the sink should not be higher than the water filter screen and should not be too low.

 

10. Before the workpiece enters the powder spraying chamber, turn on the fan, illuminate, spray the main power supply, and start spraying when the workpiece is fed. Clean the powder path of the spray machine before work, collect the recovered powder, put it into the powder drum or the powder box after sieving, turn off the power and air source; clean and check the filter element regularly.

 

11. The drying room should be kept clean and the damaged quartz tube should be replaced in time. When replacing the quartz tube, the terminal should be tightened.

 

12. Five emergency stop buttons arranged on the painting line, so that there is a problem in production and stop in time. After checking the problem, unscrew the emergency stop button and continue working.
