粉体喷涂线集中供粉中心是粉体喷涂生产线的核心供粉枢纽，主要负责对粉末涂料进行集中储存、精准分配与稳定输送，为整条生产线的多个喷涂工位（如手动喷涂室、自动喷涂机器人）提供持续且均匀的粉末原料。

从结构来看，该中心通常包含粉末储存罐（配备料位监测与防尘装置）、负压输送系统（由真空泵、输送管道组成，避免粉末堵塞）、粉末分配阀（可按需调节各工位供粉量）及控制系统（实时监控供粉压力、流量，确保参数稳定）。其工作流程为：粉末涂料先存入储存罐，经负压输送系统输送至分配阀，再由分配阀将粉末精准分配至各喷涂工位的供粉桶，全程实现自动化管控。

该设备的核心优势在于：一是提升供粉稳定性，避免分散供粉时各工位粉末浓度差异导致的涂层色差，保障产品质量一致性；二是提高粉末利用率，集中回收输送过程中的残留粉末，减少浪费；三是优化生产管理，通过集中控制可实时调整供粉参数，且便于统一进行粉末种类切换，适配多品种工件的喷涂需求。目前广泛应用于汽车零部件、家电外壳、五金件等规模化粉体喷涂生产线，尤其适合喷涂工位较多、对涂层质量要求高的生产场景。

The Centralized Powder Supply Center for Powder Spray Line is the core powder supply hub of the powder spray production line. It is mainly responsible for centralized storage, precise distribution and stable transportation of powder coatings, providing continuous and uniform powder raw materials for multiple spraying stations (such as manual spray booths and automatic spray robots) in the entire production line.

In terms of structure, this center usually includes a powder storage tank (equipped with a level monitoring and dust-proof device), a negative pressure conveying system (composed of a vacuum pump and conveying pipelines to avoid powder blockage), a powder distribution valve (which can adjust the powder supply volume of each station as needed) and a control system (which monitors the powder supply pressure and flow in real time to ensure stable parameters). Its working process is as follows: the powder coating is first stored in the storage tank, then transported to the distribution valve through the negative pressure conveying system, and then the distribution valve accurately distributes the powder to the powder supply barrels of each spraying station, realizing automatic control throughout the process.

The core advantages of this equipment are: first, it improves the stability of powder supply, avoids coating color difference caused by the difference in powder concentration between stations during decentralized powder supply, and ensures the consistency of product quality; second, it improves the powder utilization rate by centrally recovering the residual powder during transportation and reducing waste; third, it optimizes production management. Through centralized control, the powder supply parameters can be adjusted in real time, and it is convenient to uniformly switch powder types to adapt to the spraying needs of multi-variety workpieces. At present, it is widely used in large-scale powder spray production lines for auto parts, home appliance casings, hardware parts, etc., especially suitable for production scenarios with many spraying stations and high requirements for coating quality.
