In today's manufacturing industry, the appearance and performance of products are the focus of concern for enterprises. Especially in the field of plastic products, how to ensure that the coating of the shell is both beautiful and durable has become a key link in production and manufacturing. For this reason, the automatic dust-free coating production line has emerged, designed specifically for the surface coating of plastic shells. It can achieve an integrated system of automatic ground transportation, automatic spraying, and automatic drying, ensuring efficient and accurate coating.
1. Characteristics of production line
This production line not only includes basic painting processes, but also incorporates advanced technologies such as painting workshop purification, indoor cooling, and secondary exhaust gas treatment systems. Specifically, it is combined with the coating production process of PU/UV paint, making the coating stronger and brighter.
2. Design highlights
-Workshop layout: This production line clearly distinguishes different functional areas such as product suspension area, online and offline packaging area, dust removal area, and spraying and curing area, ensuring that the entire production process is orderly.
-Spray environment: The spray operation environment in the purification workshop and clean room reduces dust and impurities, ensuring the quality of the coating.
-Line structure and conveying method: According to customer needs, the line structure can be designed as one coating and one baking, two coatings and two baking, or even three coatings and three baking. The automatic rail chain conveyor system can adjust the conveying speed according to product characteristics and production requirements, ranging from 0.5-6m/min, while the design speed is 2.5m/min.
-Spraying and baking: using fixed wooden compartment automatic spraying technology, equipped with positive and negative rotation mechanism devices. The baking part adopts infrared electric heating and ultraviolet UV light curing to ensure that the coating is cured quickly and uniformly.
3. Process flow
Starting from manual dust removal, then to fixture assembly and transportation, automatic electrostatic dust removal, primer spraying, leveling, curing, topcoat spraying, leveling, curing, and finally UV curing and quality inspection packaging, every step is strictly controlled to ensure production efficiency and product quality.
conclusion
This automatic spraying production line provides an advanced and efficient solution for plastic shell coating, ensuring the continuity of production and the quality of coating. With the continuous advancement of production technology, it is believed that there will be more innovations and breakthroughs in the future to make coating technology more perfect.
