Product Overview
The Keypack Intelligent Vertical Granule Packaging Machine is designed for precise weighing and filling of granular materials into pre-made bags. It delivers ±0.1%-0.2% packing accuracy with servo-driven lifting system, automatic weighing, and PLC touch screen control. Ideal for rice, pet food, sugar, fertilizer granules, and other free-flowing or poor-flowing granular products across food, pet food, and agricultural industries.
This vertical packaging machine combines gross weight measurement with pneumatic bag clamping and servo-controlled lifting for dust-free, high-precision granule packaging. The Keypack Intelligent (Kunbupack) automatic bag packaging machine features gate feeding with vibration supplement or optional dual vibration feeding modes, supporting packing weights from 10-25kg (standard model) and 10-50kg (large model) at speeds of 1-2 bags per minute.
Key Features and Machine Characteristics
Pneumatic Bag Clamping with High-Speed Weighing System
The pneumatic bag clamping device and support bracket are mounted on weight sensors, enabling fast and slow filling based on preset weights. The high-response automatic weighing system ensures high packing accuracy of ±0.1%-0.2%, making this premade bag filling and sealing machine suitable for precise granule dosing applications.
Servo-Driven Lifting System for Dust-Free Operation
A servo motor drives the tray lifting mechanism with adjustable lifting speed settings. During filling, the system operates with minimal dust emission, protecting the workshop environment. This vertical packaging machine design is particularly effective for handling granular materials that require dust-free powder handling and clean packaging conditions.
Servo Motor and Drive Control for Stable Performance
The servo motor and servo drive control the screw mechanism, delivering stable performance and high precision. This ensures consistent filling accuracy across different granular materials, from free-flowing rice and sugar to poor-flowing pet food and fertilizer granules.
PLC Touch Screen Control for Simple Operation
The PLC touch screen control system provides an intuitive human-machine interface for easy operation and parameter adjustment. Operators can quickly switch between quantitative mode (faster speed, standard accuracy) and real-time weighing mode (higher accuracy, moderate speed) to optimize production efficiency based on product requirements.
Full Stainless Steel Construction with Easy Cleaning
The entire bag feeding machine features full stainless steel construction. The combined or open-type hopper design allows for convenient cleaning and maintenance, meeting GMP standard requirements for food and pharmaceutical applications. The fixed screw installation structure ensures filling operations do not affect material properties.
Adjustable Filling Head for Multiple Specifications
The filling head is equipped with a hand wheel for height adjustment, enabling easy adaptation to multiple packaging specifications. This flexibility allows the premade pouch fill and seal machine to handle various bag sizes and filling requirements without complex changeover procedures.
Dual Device Options for Bags and Canisters
The machine offers pneumatic bag clamping device and canister device options. By selecting different devices, the automatic bag packaging machine can satisfy both bag packaging and canister packaging requirements, providing versatile production capabilities for different packaging formats.
Switchable Working Modes for Optimized Performance
Two working modes are available: quantitative mode offers faster speed with standard accuracy, while real-time weighing mode provides higher accuracy with moderate speed. This flexibility allows operators to balance speed and precision based on product specifications and quality requirements.
