The roller coater sends the coating to the spray gun through the transmission system, and atomizes the coating by compressing it to the spray gun to spray it evenly on the workpiece surface. This machine is generally used for finishing artificial leather and synthetic leather, which can meet the production requirements of different decoration processes. What is the reason why roller coater is widely used?
1. The coating is standard, fast and convenient, and the quality is stable. Because the roller coater automatically sprays according to the set procedure in the spraying process, it effectively avoids the uneven coating surface caused by inconsistent gun walking or inconsistent spraying distance and height in the manual spraying process. The quality of the workpiece sprayed by the roller coater is particularly stable.
2. Good spraying effect and cost saving. Roller coater is an independent automatic coating equipment. It can be produced according to the specific spraying requirements of customers. Roller coater generally adopts multi axis and multi spray gun spraying, which can complete the spraying of multiple workpieces at one time. Compared with manual spraying, it not only improves the spraying efficiency of the workpiece, but also greatly saves the labor cost.
3. The coating utilization rate is particularly high. Generally, mixed atomized coatings are used, which not only improves the working efficiency of coatings, but also effectively reduces the traditional air atomization overspray phenomenon and paint mist rebound.
Operation method of roller coater:
1. First adjust the coating to the required construction viscosity and construction humidity.
2. Then start the test run of paint delivery pump and painting machine, adjust the narrow seam width of painting head, and start normal production after meeting the requirements.
3. Open the conveyor and adjust the transmission speed ratio.
4. Finally, the test piece shall be coated first to determine the coating thickness and the effect after coating. Production can be carried out normally only after meeting customer requirements.
