The coating machine may have some common failures during work, which affect production efficiency and product quality. The following are some common failures and solutions of the coating machine:
First, the coating film is uneven
Failure cause: unbalanced coating rod or scraper, resulting in uneven coating thickness.
Solution: Check the installation of the coating rod and scraper, adjust the coating roller and scraper to ensure their balanced installation.
Second, the coating wrinkles
The cause of the failure: the substrate is not fixed evenly or the pressure of the coating rod is not enough.
Solution: Adjust the position and pressure of the coating rod and pressure roller. If the film substrate is not flat, positive vacuum adsorption can be considered.
Third, the film thickness is insufficient or too thick
The cause of the failure: the coating speed does not match, resulting in insufficient or excessive coating thickness.
Solution: Adjust the coating speed to ensure that the coating thickness meets the requirements.
Fourth, the coating machine stops working
Fault causes: power failure, transmission system failure, etc.
Solution: Check the power supply and transmission system to repair the malfunction.
Five，Insufficient or blocked coating liquid
Fault cause: insufficient coating liquid or pipeline blockage.
Solution: Check the coating liquid supply system to ensure that the coating liquid is sufficient and the pipeline is smooth.
Six，The noise of the coating machine is too loud
Failure cause: There is a problem with the transmission system or coating mechanism.
Solution: Check the transmission system and coating mechanism to repair problems and reduce noise.
The above are the common failures and solutions of the coating machine. Operators should pay attention to regular inspection and maintenance when using the coating machine, detect and resolve faults in a timely manner, and ensure the normal operation of the coating machine.
