Automatic Ice Cube Pouch Weighing and Packaging Machine

Application:
The LD-720AS Vertical Weighing Packaging Machine is designed for efficiently packing a wide range of free-flowing or slightly sticky products. It is ideal for ice cubes, frozen fruits, vegetables, and seafood, as well as large granular items such as sugar, salt, coffee beans, pet food, and small snacks.

Package Type:
The LD-720AS is designed for pillow bags, gusseted bags, and back sealing pouches, providing flexible packaging styles for different product sizes. It supports single or multiple weight packs according to production needs. The finished bags are strong, neat, and airtight, ensuring excellent protection for ice cubes or granular products.

Wide Application Range: 
The LD-720AS Vertical Weighing Packaging Machine is a high-performance model designed for packing heavy, irregular, or wet products such as ice cubes and frozen foods. Built with a durable stainless-steel structure and waterproof design, it ensures reliable performance in cold or humid environments. Equipped with a precision multi-head weigher and servo-driven film system, it delivers stable operation, accurate weighing, and strong sealing for extended product freshness.

This machine is widely used in the frozen food and cold-chain packaging industries, offering a versatile solution for a wide range of granular or block-type products, including:

Ice Products: Such as cube ice, crushed ice, and tube ice

Frozen Fruits & Vegetables: Diced mango, pineapple, mixed berries, peas, and corn

Seafood Products: Shrimp, scallops, small fish, squid rings, and other frozen seafood 

Frozen Prepared Foods: Dumplings, meatballs, and other ready-to-cook frozen products

Workflow: 

1. Product Feeding: Ice cubes or other granular materials are lifted from the ground hopper to the top of the machine by a Z-type elevator, ensuring smooth and continuous product feeding without damage or melting.

2. Accurate Weighing: A high-precision multi-head weigher automatically measures the target weight for each pack, providing both speed and accuracy while minimizing product loss.

3. Bag Forming: The film roll is pulled down by a servo-driven system and shaped into a bag through the forming tube. The system supports various bag types and sizes for different packaging needs.

4. Product Filling: The weighed ice cubes or granular products are dropped precisely into the formed bag, with anti-stick and anti-splash design to maintain cleanliness and product integrity.

5. Sealing and Cutting: The machine performs reliable heat sealing and cutting simultaneously, creating air-tight, neat seals that protect the product from leakage, moisture, and contamination.

6. Finished Product Output: Packed bags are discharged onto the output conveyor, ready for weighing check, boxing, or palletizing, ensuring a smooth and efficient end-to-end workflow.

Working Principle of LD-720AS Vertical Packaging Machine:

The LD-720AS works with a two-head linear weigher to achieve precise and automatic weighing. Ice cubes or granular materials are lifted by a Z-type elevator and evenly fed into the weighing hoppers. The linear weigher accurately measures the set weight and discharges the product into the vertical form-fill-seal system. The machine then forms the bag, fills the product, seals it with heat, and cuts it into individual packs. The entire process runs smoothly, ensuring accuracy, speed, and perfect sealing performance.

Feature:

Z-Type Elevator Feeding System The Z-type elevator gently lifts ice cubes or granular materials from the ground hopper to the weighing unit. Its sturdy stainless-steel structure and smooth conveying buckets prevent melting, sticking, or product damage while ensuring a continuous, stable feeding process.
	Two-Head Linear Weigher Equipped with dual weighing hoppers for alternating operation, this system provides accurate and stable weighing performance at a cost-effective level. It is ideal for larger or heavier particles such as ice cubes, frozen vegetables, or pet food. Each head works independently for consistent output and precise portion control.
Vertical Form-Fill-Seal Structure The main unit integrates film pulling, bag forming, filling, sealing, and cutting in one compact design. A servo-driven film transport system ensures smooth movement and precise bag length control, reducing film waste and improving sealing alignment.
	Advanced Sealing and Cutting System The machine uses high-efficiency heat sealing jaws with uniform temperature distribution, guaranteeing tight and durable seals even in cold or humid environments. The system minimizes leakage, air penetration, and contamination — keeping products fresh and presentable.
Smart & Simple Control Interface Equipped with a PLC and color touchscreen, the control system allows operators to easily adjust weighing parameters, bag sizes, and sealing temperatures. Its intuitive interface includes real-time monitoring, alarm functions, and quick troubleshooting for easy operation and minimal downtime.
