Screw Powder Automatic Packaging Machine

HTL-D Series Intelligent Vertical Packaging Machines

Main Performance and Structural Features

The HTL-D series represents a new generation of intelligent vertical packaging equipment designed for efficiency, automation, and reliability. These machines integrate seamlessly with metering devices to fully automate the entire packaging cycle—from measuring and feeding to filling, bag forming, sealing, and finished product output.

Key Features:

• Robust and Rational Design: The overall mechanical structure is compact and logically arranged, making daily operation, adjustment, and maintenance highly convenient.
• Advanced Film Transport System: Equipped with a servo-driven film pulling system and synchronous belt mechanism, ensuring precise, smooth, and stable film transport.
• Automatic Film Correction Function: Automatically corrects alignment deviations during operation, reducing film waste, saving time, and enhancing the overall reliability and intelligence of the packaging process.
• Multiple Alarm and Protection Functions: Includes built-in safety mechanisms that alert operators of abnormalities—significantly improving machine safety and energy efficiency.
• Fully Integrated Process Automation: The machine, when paired with appropriate metering devices, can automatically complete:
• Product weighing
• Feeding
• Filling
• Bag forming
• Date printing
• Gas flushing or exhaust
• Final product discharge
• Flexible Bag Types: Supports various packaging styles including pillow bags, vertical (gusseted) bags, and hanging hole bags, offering versatility for a wide range of applications.

Available Models and Technical Specifications

HTL-D420

Designed for medium-volume packaging tasks, this model supports bag sizes between 80–300 mm in length and 80–180 mm in width. The measuring range is from 50 to 1000 ml. It operates at a speed of approximately 30 packs per minute, depending on film quality and product characteristics. Measurement accuracy is maintained within ±1.5g. This model is compatible with film of standard thickness and is ideal for common pouch packaging needs.

HTL-D520

This higher-capacity model accommodates larger bag sizes, with lengths between 80–350 mm and widths from 100–250 mm. Its measuring capacity ranges from 150 to 2000 ml. Like the D420, it also runs at a speed of around 30 packs per minute with an accuracy of ≤1.5g. Suitable for bulkier products or applications requiring larger pouch dimensions, while maintaining the same performance reliability and automation benefits.
