Vertical Packing Machine for Powder and Granule Products

Product Introduction

The Vertical Packing Machine for Powder and Granule Products is designed to automate weighing, feeding, bag forming, filling, sealing, and finished-package discharge within one continuous packaging process. Combined with a 10-head weighing system and material conveying equipment, it provides an efficient solution for manufacturers seeking consistent packaging performance with reduced manual handling.
The machine supports multiple sealing formats, including back sealing, three-side sealing, and four-side sealing, and works with common packaging films such as OPP/CPP, OPP/PE, NY/PE, and PE. For the 420 mm configuration, finished bag widths range from 60–200 mm and bag lengths from 80–300 mm, with packaging speeds of approximately 5–60 bags per minute depending on bag dimensions and product characteristics.
PLC control, material-level sensing, precise weighing, stable film forming, and controlled heat sealing help maintain reliable operation throughout production. Optional functions including nitrogen filling, date printing, gas flushing, and bag punching can be added according to individual packaging requirements.

7. Stable Bag Forming
The bag-forming structure guides packaging film through the forming process and helps reduce material interference around the sealing area. Forming components can be customized according to bag requirements.

8. Controlled Heat Sealing
The sealing system applies consistent heat to the packaging film to support reliable bag closure. Sealing parameters can be adjusted according to the selected film material.

9. Flexible Packaging Film Compatibility
Suitable film options include OPP/CPP, OPP/PE, NY/PE, and PE, allowing the machine to accommodate different product and packaging requirements.

10. Optional Packaging Functions
Optional configurations include nitrogen filling, gas flushing, date printing, and punching devices, allowing the machine to be adapted to different production processes.

Technical Specifications

 

How the Vertical Packing Machine Works

The packaging process can be organized as:
Material Feeding → Elevator Conveying → Multihead Weighing → Film Forming → Product Filling → Bag Sealing → Cutting → Finished Product Discharge
Bulk material is first supplied to the feeding system and transferred upward by the material elevator. The weighing system portions the required amount before releasing the product into the forming tube.
At the same time, packaging film is pulled through the forming structure and shaped into a bag. The measured product enters the formed package, after which the sealing system closes and cuts the bag. Finished packages are then discharged for downstream handling.

Main Component Details

PLC Control Panel
The PLC-based control system provides centralized management of packaging parameters. Operators can adjust settings such as filling quantity and operating speed through the interface, while multilingual display options can be configured for different markets.

Intelligent Sensor
The sensor detects material levels during production and works with the feeding system to help maintain an appropriate product supply to the weighing unit.

10-Head Multihead Weigher
The weighing system combines multiple weighing heads to determine the required product quantity before discharge. This configuration supports efficient portion control and helps improve packaging consistency.

Bag Forming Device
Packaging film passes around the forming structure to create the required bag shape before filling. The forming components can be adapted according to bag width and packaging requirements.

Sealing System
The heat-sealing area closes the formed bag after filling. Temperature settings can be adjusted according to film characteristics to help produce consistent seals.

Material Conveying Elevator
The elevator continuously transfers bulk product from the lower feeding hopper to the weighing system positioned above the packaging machine, reducing the need for manual material loading at height.

Finished Product Conveyor
After sealing and cutting, finished bags are discharged from the vertical packaging machine and transferred away from the packaging area for collection or connection with downstream equipment.

 

Application Industries

Food Processing
