The roller coater machine mainly consists of a coating mechanism and a steering support mechanism. The driving of the roller coater machine is divided into collective driving and single-roll driving. Collective driving refers to all the rollers of the roller coater machine being driven by one electric motor, and this driving mode is not easy to change the process technology parameters. Single-roll driving is to configure a dedicated DC motor for each roller, which can change the rotating direction and speed arbitrarily, and it is easy to change the process technology parameters. Roller coater machines with high production speed often set up two coating heads. There are two coating heads on the front of the coiled material, and the purpose of setting two coating heads is to quickly replace the coating and coating rollers.
UV roller coater is widely used, but incorrect usage can reduce the machine life. So, what is the correct method of using UV roller coating machine:
Regularly oil the transmission rollers of the conveyor belt to prevent poor contact between the conveyor belt and the rollers.
After use, pour the washing water into the glue roller and steel roller to clean the glue roller and steel roller until there are no impurities. Turn off the power, adjust the left and right adjustment handwheels of the steel rollers counterclockwise to loosen the glue roller and steel roller until they no longer contact, and then clean the conveyor belt to make it clean and free of impurities.
When painting on the workpiece: first pour a suitable amount of paint between the glue roller and the steel roller. The rotation of the roller will evenly distribute the paint on the glue roller and the steel roller. After fully wetting, place the workpiece on the conveyor belt and roll coating according to the requirements. If a thick coating is needed, roll several times.
Adjust the rotating speed of the UV roller coating machine glue roller according to the viscosity of the paint, and then adjust the conveyor belt to the appropriate speed.
Rotate the left and right adjustment handwheels of the steel roller clockwise to tighten the distance between the steel roller and the glue roller according to the requirements of the thickness of the coating and the viscosity of the paint, and adjust it to the appropriate tightness.
Adjust the height of the glue roller first. Turn the height adjustment handwheel to adjust the distance between the glue roller and the workpiece that needs to be painted. Generally, it is best to adjust it to the point where the roller cannot be pulled out, and then remove the roller plate for backup.
Before using the UV Roller Coater every time, you must observe whether there are any impurities on the glue roller and steel roller. If there are impurities, you need to clean them with UV special washing water.
On the control plane, clockwise rotate the red emergency stop button to pop it out, wait for the digital display screen to stabilize, and then press the motor switch to turn on the power.
