Semi-Automatic Vertical Powder Packaging Machine

Product Overview

The Keypack Intelligent Semi-Automatic Vertical Powder Packaging Machine is designed for precise filling and sealing of pre-made bags with powdered and granular materials. It delivers ±0.2% packing accuracy with servo-driven screw control, PLC touchscreen interface, and GMP-compliant stainless steel construction. Ideal for milk powder, protein powder, flour, pharmaceutical powders, chemical powders, and seasoning packaging across food, pharmaceutical, and chemical industries.

This semi-automatic powder filling machine combines manual bag placement with automated weighing, clamping, filling, and sealing operations. The Keypack Intelligent (Kunbupack) vertical packaging machine features a gross weight measurement method with valve feeding and spiral supplement filling modes, supporting packing weights from 5-25kg and 10-50kg ranges at speeds of 2-5 bags per minute.

Key Features and Machine Characteristics

Full Stainless Steel Construction with GMP Compliance

The entire powder packaging machine is constructed from stainless steel, with 304 stainless steel used for all product contact surfaces. This design satisfies GMP standards, food hygiene certifications, and corrosion-resistant requirements for chemical powder packaging applications. The sealed air-damped glass and stainless steel combination hopper provides clear visibility of material flow while preventing dust leakage, maintaining a clean workshop environment.

PLC Touchscreen Interface with Weighing Sensor Feedback

The PLC screen control system offers stable operation, high interference resistance, and precise weighing accuracy. The intuitive touchscreen HMI simplifies parameter adjustment and monitoring. The weighing sensor provides specific gravity tracking feedback, compensating for material density variations to maintain consistent packing weights and overcome weight fluctuations caused by powder bulk density changes.

Servo Motor-Driven Filling System

This auto powder filling machine utilizes servo motor drive for the filling screw, delivering high positioning accuracy, strong torque, extended service life, and adjustable rotation speed. The servo-driven system ensures precise and repeatable dosing for both free-flowing and poor-flowing powders, from ultra-fine powders to larger granular materials.

Maintenance-Free Stirring Motor

The agitator employs a Taiwan-made maintenance-free reduction motor featuring low noise, long service life, and lifetime maintenance-free operation, reducing downtime and operational costs.

Flexible Operation with Recipe Storage

The semi-automatic powder filling machine allows stepless adjustment during packaging operations, enabling operators to switch working states freely for convenient operation. The system stores up to 10 product-specific parameter recipes for quick changeovers between different powder formulations, supporting versatile production requirements.

Interchangeable Screw Accessories for Various Materials

By replacing screw accessories, the powder packing machine adapts to a wide range of materials from ultra-fine powders to large granules. This flexibility makes it suitable for diverse applications including detergent powder, instant drink powder, spice powder, and chemical powder packaging.

Advanced Control Functions

Select models feature overshoot suppression, drop compensation, over-tolerance alarm functions, and timed automatic cleaning. The dual-section PVC conveyor belt facilitates easy residue removal, and the screw can be directly pulled out for independent cleaning, simplifying maintenance procedures.

Dust Collection and Environmental Protection

The filling outlet is equipped with a dust collection device to protect the workshop environment and ensure operator safety when handling fine powders such as flour, seasoning, or pharmaceutical powder.
