Description

Glue solution feeding mechanism of coating machine Technical Field The utility model relates to the technical field of coating, in particular to a glue feeding mechanism of a coating machine. Background In the coating field, the coater is used as a core device, and the running stability and the coating quality are important. The glue solution is used as a key material in the coating process, and the accurate monitoring and effective control of the liquid level directly affect the normal development of the coating operation and the quality of the final product. Traditional coater glue level monitoring often relies on manual operation. The worker needs to go to the coater site regularly, and estimates the glue level by directly observing the scale marks on the glue storage container or using a simple measuring tool. This approach not only consumes a lot of manpower and time, but also results in a larger error in liquid level monitoring due to the influence of human factors such as observation angle, light conditions, personal judgment differences, and the like. Once the liquid level judgment is inaccurate, the problems of coating interruption caused by insufficient glue solution or glue solution waste and environmental pollution caused by excessive overflow of the glue solution can occur, and the production efficiency and the product quality are seriously affected.
