Product Overview

The Keypack Intelligent Semi-Automatic Vertical Granule Packaging Machine with Lifting System is a high-precision, semi-automatic solution designed for metering and packaging free-flowing and poor-flowing granular materials. It is suitable for rice, grains, cat food, dog food, white granulated sugar, soft white sugar, monosodium glutamate (MSG), flavors and fragrances, chemical fertilizer granules, and other granular products.
This vertical packaging machine integrates weighing, filling, and controlled lifting into one stable system. By combining a high-response weighing system with servo-driven screw filling and tray lifting, the machine ensures accurate automatic weighing while effectively controlling material dispersion during filling. Equipped with PLC touch screen control, it is ideal for manufacturers seeking a semi-automatic vertical granule packaging machine with reliable performance for bagging or container filling applications.

Key Features and Machine Characteristics

• High-Precision Automatic Weighing System
  The pneumatic bag clamping device and support bracket are mounted directly on the load cell, enabling automatic switching between fast filling and slow filling according to the preset target weight. This design ensures stable and accurate automatic weighing performance for granular packaging applications.

• Servo-Controlled Lifting with Clean Operation
  The tray lifting system is driven by a servo motor with adjustable lifting speed. During filling, material dispersion is effectively reduced, helping to maintain a cleaner working environment and supporting dust-controlled packaging for granular products.

• Servo-Driven Screw Filling System
  A servo motor and servo drive control the screw filling mechanism, providing stable operation and high filling precision. The fixed screw installation structure ensures that material properties are not affected during the filling process.

• PLC Touch Screen Control
  The Keypack Intelligent (Kunbupack) vertical granule packaging machine is equipped with a PLC control system and touch screen HMI, allowing easy operation, parameter setting, and stable control throughout the packaging process.

• Full Stainless Steel Structure
  The machine features a full stainless steel construction with a combined or open-type hopper, ensuring durability and allowing convenient cleaning. This structure supports hygienic operation for food granules and meets the requirements of GMP-standard weighing and packaging environments.

• Adjustable Filling Head for Multiple Specifications
  The filling head height can be adjusted via a handwheel, enabling quick adaptation to different bag sizes and packaging specifications.

• Flexible Bagging and Canning Configuration
  Optional pneumatic bag clamping devices or tank holding devices allow the machine to meet both bagging and canning requirements. The system can be used in granular bag packaging, pre-made bag filling and sealing, or other bag feeding machine applications.

• Dual Working Modes
  The machine supports two selectable modes:

  • Fixed-Quantity Mode, offering higher packaging speed with slightly lower precision

  • Real-Time Weighing Mode, providing higher accuracy with slightly reduced speed
