PVA Powder Packaging Machine

Valve-type automatic weighing and quantitative packing scale is commonly used for packaging powdery materials with high gas content or light specific gravity and poor fluidity, such as carbon black, talc powder, calcium carbonate, and ceramic powder. The scale integrates automatic breaking, weighing, bagging, and sealing, significantly reducing subsequent workload and minimizing dust emission during packaging.

Main Features:

◆ Fast and slow feeding is controlled by PLC program; fast program is used initially, switching to slow feeding when 90% of the rated weight is reached.

◆ High-precision screw feeding, the feeding nozzle is equipped with a dust-proof device to prevent dust emission; optional bag-matching screw mechanism for different bag sizes.

◆ Bag vibrating during packaging to accelerate speed and ensure a neat, smooth bag appearance.

◆ Automatic tare, zero reset, and data self-correction function for using bags of different sizes or weights.

◆ Low material level alarm and automatic stop of packaging, system enters standby program automatically.

◆ Breaking function during feeding ensures continuous, smooth material flow into the conveying screw and bag.

◆ The instrument has a counting function; a printer can be equipped if printing is required.

◆ Instrument with RS232 or RS485 interface.

◆ Integrated cabinet design for easy installation and movement.
