　　设备组成涂装流水线的七大组成部分主要包括：前处理设备、喷粉系统、喷漆设备、烘炉、热源系统、电控系统、悬挂输送链等。

　　The seven major components of the equipment composition coating assembly line mainly include: pre-treatment equipment, powder coating system, spray painting equipment, oven, heat source system, electrical control system, suspension conveyor chain, etc.

　　1、前处理设备喷淋式多工位前处理机组是表面处理常用的设备，其原理是利用机械冲刷加速化学反应来完成除油、磷化、水洗等工艺过程。钢件喷淋式前处理的典型工艺是：预脱脂、脱脂、水洗、水洗、表调、磷化、水洗、水洗、纯水洗。前处理还可采用抛丸清理机，适用于结构简单、锈蚀严重、无油或少油的钢件。且无水质污染。

　　1. The spray type multi station pre-treatment unit is a commonly used equipment for surface treatment. Its principle is to use mechanical flushing to accelerate chemical reactions to complete processes such as oil removal, phosphating, and water washing. The typical process of spray pre-treatment for steel parts is: pre degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing, and pure water washing. Pre treatment can also use shot blasting cleaning machines, which are suitable for steel parts with simple structures, severe corrosion, and no or little oil. And there is no water pollution.

　　2、喷粉系统粉体喷涂中的小旋风+滤芯回收装置是较先进，换色较快的粉末回收装置。喷粉系统的关键部分建议选用进口产品，喷粉室、电动机械升降机等部件全部国产化。

　　2. The small cyclone and filter recovery device in powder spraying of the powder spraying system is a relatively advanced and fast powder recovery device with fast color change. It is recommended to use imported products for the key parts of the powder spraying system, and to localize all components such as the powder spraying room and electric mechanical lift.

　　3、喷漆设备如干式喷漆室、水帘式喷漆室等，广泛运用于机械制造、五金家电、电器、灯饰、塑胶件、大型装载机的表面涂装。

　　3. Spray painting equipment such as dry spray painting rooms and water curtain spray painting rooms are widely used for surface coating in mechanical manufacturing, hardware and household appliances, electrical appliances, lighting fixtures, plastic parts, and large loaders.

　　4、烘炉烘炉是涂装生产线中的重要设备之一，它的温度均匀性是保证涂层质量的重要指标。烘炉的加热方式有：辐射、热风循环及辐射+热风循环等，根据生产纲领可分单室和通过式等，设备形式有直通式和桥式。热风循环烘炉保温性好、炉内温度均匀、热损失少，经测试，炉内温差小于±3oC,达到先进国家同类产品的性能指标。

　　4. Oven drying is one of the important equipment in the coating production line, and its temperature uniformity is an important indicator to ensure the quality of the coating. The heating methods of ovens include radiation, hot air circulation, and radiation+hot air circulation. According to the production schedule, they can be divided into single chamber and through type. The equipment forms include straight through and bridge type. The hot air circulation oven has good insulation, uniform temperature inside the furnace, and low heat loss. After testing, the temperature difference inside the furnace is less than ± 3 ° C, which meets the performance indicators of similar products in advanced countries.

　　5、热源系统热风循环应用较普遍的加热方式，它利用对流传导原理对烘炉进行加热，达到工件的干燥和固化。热源可根据用户的具体情况选择：电、蒸汽、燃气或燃油等。热源箱可根据烘炉的情况而定：置于顶部、底部和侧部。生产热源的循环风机如是特制耐高温风机，则具有寿命长、能耗低、噪声低、体积小等优点。

　　5. The hot air circulation application of the heat source system is a common heating method, which uses the principle of convective conduction to heat the oven and achieve the drying and solidification of the workpiece. The heat source can be selected according to the specific situation of the user, such as electricity, steam, gas, or fuel. The heat source box can be determined according to the situation of the oven: placed at the top, bottom, and sides. If the circulating fan for producing heat sources is a specially designed high-temperature resistant fan, it has the advantages of long service life, low energy consumption, low noise, and small size.

　　6. The electrical control system for painting and painting assembly line has centralized and single row control. Centralized control can use programmable logic controllers (PLCs) to control the host, automatically control each process according to the programmed control program, collect data, and monitor alarms. Single row control is the most commonly used control method in painting production lines. Each process is controlled in a single row, and the electrical control box (cabinet) is located near the equipment, with low cost, intuitive operation, and convenient maintenance.

　　7、悬挂输送链悬输机是工业流水线、涂装线的输送系统，积放式悬输机应用于L=10-14M的仓储货架和异型路灯合金钢管涂装线。工件吊装在专用挂具上（承重达500-600KG），进出道岔平滑，道岔根据工作指令由电气控制进行开合，满足工件在各处理工位的自动输送，在强冷室、下件区域内平行积放冷却，并在强冷区域设挂具识别和牵引报警停机装置。

　　7. Hanging conveyor chain hanging conveyor is a conveying system for industrial assembly lines and painting lines. The stacking hanging conveyor is applied to L=10-14M storage shelves and special-shaped street lamp alloy steel pipe painting lines. The workpiece is lifted on a dedicated hanging fixture (with a load capacity of 500-600KG), and the entry and exit switches are smooth. The switches are electrically controlled to open and close according to work instructions, meeting the automatic conveying of workpieces at various processing stations. Parallel accumulation cooling is carried out in the strong cooling room and the unloading area, and hanging fixture recognition and traction alarm shutdown devices are installed in the strong cooling area.
