Large-Cyclone Powder Spraying System for Branded Educational Equipment
Equipment Overview

Automated electrostatic powder coating system designed for metal educational equipment, featuring high-efficiency powder recovery and environmentally friendly coating pre-treatment solutions.

Working Principle

PLC-controlled system manages powder spray pressure, electrostatic voltage, and reciprocator stroke. Educational equipment workpieces undergo multiple processing stages including automatic spraying, overspray collection, large-cyclone separation, and secondary fine filtration.

Core Advantages
  • Full Automation: Continuous multi-variety batch production with minimal manual intervention
  • High Precision Coating: Programmable parameters ensure consistent thickness and color on irregular surfaces
  • Energy Efficient Operation: Large-cyclone separation system minimizes powder waste and reduces energy consumption
  • Wide Application Range: Suitable for school furniture, teaching instruments, sports equipment, and electronic enclosures
Process Flow
Loading & Conveying → Electrostatic Powder Booth Entry → Automatic Electrostatic Powder Coating → Manual Touch-Up → Overspray Powder Large-Cyclone Separation → Sieve Machine Recycling → Exhaust Gas Secondary Filtration & Discharge → Curing Oven Transfer → Unloading
