Dust Proof Automatic Weighing Machine

The Dust Proof Automatic Weighing Machine is a specialized quantitative batching system developed for melamine tableware production lines. It performs automatic weighing and discharging of melamine molding powder. Its fully enclosed dust-proof structure effectively prevents powder from escaping during feeding and weighing.

Equipped with a high-precision weighing sensor and a PLC touch-screen control system, the machine replaces traditional manual weighing. It ensures stable feeding weight, reduces raw material waste, and improves workshop cleanliness. It can be paired with a melamine preheating machine and a hydraulic molding press to form a complete automatic melamine production line.

• Excellent Dust-Proof Design: Fully sealed hopper and feeding channel structure greatly suppress powder flying, reduce material loss, keep the workshop clean, and lower equipment cleaning frequency.
• High Weighing Accuracy: A high-precision load cell sensor keeps weighing error within ±1–2 g. Consistent material weight per batch lowers the defective rate of finished melamine tableware.
• Intelligent PLC Touch Control: Multiple weight formulas can be stored in the system, allowing quick recipe switching for bowls, plates, cups, and trays when changing molds. Operation is simple for workers.
• Stable Vibratory Feeding: Dual-speed vibration feeding combines fast coarse feeding with slow fine feeding, balancing weighing speed and precision for long-time continuous industrial operation.
• Easy Disassembly & Cleaning: Quick-release structure for the hopper and flow channel makes it convenient to take apart, clean, and switch between different types of melamine powder without cross contamination.

1. Set the target weight on the touch screen according to the mold requirement.
2. Start the machine; the vibrator feeds powder into the weighing hopper.
3. Coarse feeding begins first, then switches to fine feeding as the target weight is approached.
4. Feeding stops automatically once the preset weight is reached.
5. The quantitative powder is discharged automatically.
6. The weighed powder is sent to the high-frequency preheating machine.

Mainly used in melamine dinnerware factories for quantitative batching of melamine powder, including the production of melamine bowls, plates, dishes, trays, children's tableware, and canteen tableware.
