Structure and Working Principle of Single-Axis Online Spray Coating Equipment for High-End Watch Case Surface Treatment

The single-axis online automatic spray coating equipment is equipped with a precision conveyor chain, a professional moving servo axis, and an intelligent spray gun system. Relying on the stable reciprocating and uniform speed movement of the spray gun, it performs full-coverage spray coating on continuously flowing workpieces on the conveyor line, ensuring uniform paint film thickness and high coating consistency. It is suitable for batch online coating production of various regular workpieces such as switch panels and plastic parts.

The equipment adopts a compact modular design, with a simple and reasonable structure, small footprint, and high production smoothness. A high-precision pressure equalization purification box is installed above the spraying area, continuously supplying clean fresh air to effectively purify the spraying environment, preventing dust and impurities from adhering to the workpiece surface, and significantly improving paint surface smoothness and product yield.

A dedicated paint collection box is installed at the bottom of the equipment to centrally collect excess paint and reduce material waste; a dedicated paint mist exhaust channel is reserved on the side to promptly dissipate paint mist generated during operation, improving the workshop working environment and meeting environmental protection production standards.

The machine is equipped with an adjustable speed drive motor, which can flexibly adjust the conveying and spraying speed according to the workpiece material, spraying process, and production capacity to adapt to the coating needs of different products. Combined with a PLC intelligent touch control operating system, it features visualized parameter adjustment, one-button start/stop, and simple and convenient operation. The equipment operates stably with a low failure rate, and even beginners can quickly learn to operate it, truly achieving high-efficiency, high-precision, easy-to-operate, and labor-saving automated online spraying production.
