Product Overview

The Keypack Intelligent Semi-Automatic Vertical Granule Packaging Machine is a semi-automatic packaging solution designed for metering and filling 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 automatic weighing and screw filling into a compact structure. With a weighing feedback system and PLC touch screen control, the machine delivers stable packaging accuracy while adapting to different material characteristics. It is an ideal choice for manufacturers seeking a semi-automatic vertical granule packaging machine for reliable bag packaging and weighing applications.

Key Features and Machine Characteristics

• Full Stainless Steel Structure with Hygienic Design
  The Keypack Intelligent (Kunbupack) vertical granule packaging machine features a full stainless steel structure and a combined or open-type transparent hopper. The hopper can be easily disassembled and cleaned without tools, supporting hygienic operation and meeting GMP-standard weighing and packaging requirements.

• Servo-Driven Screw Filling System
  A servo motor and servo drive are used to control the screw filling mechanism, ensuring stable performance and precise control during granular material filling.

• PLC Touch Screen Control System
  The machine adopts PLC control with a touch screen human-machine interface (HMI), enabling easy operation, parameter adjustment, and reliable control throughout the packaging process.

• Weighing Feedback with Specific Gravity Tracking
  Designed with a weighing feedback system that tracks material specific gravity, the machine effectively overcomes packaging weight variation caused by changes in material density, improving automatic weighing accuracy for granular products.

• Recipe Storage for Multiple Products
  Adjustment parameters and formulas for different products can be stored for later use, with support for up to 10 product formulas, allowing quick changeover between various granular materials.

• Wide Material Adaptability via Screw Replacement
  By replacing screw accessories, the machine can adapt to a wide range of materials, from ultra-fine powder to small granules, enhancing flexibility across different packaging applications.

• Load-Cell-Mounted Bag Clamping Structure
  The pneumatic bag clamping device and support bracket are mounted directly on the load cell, ensuring stable force transmission and consistent weighing performance during bag packaging operations.
