What is a Bag Opener Machine?

The bag opener (bag breaker) machine is used to open plastic bags, woven bags, and other types of waste bags, then convey the material to the sorting and crushing system. This equipment replaces traditional manual bag-cutting, improving sorting efficiency.
The bag opener machine utilizes main and auxiliary bag opener blades of different shapes that rotate at varying speeds in opposite directions to cut through plastic bags, woven bags, and other materials. It features a user-friendly stepless speed control design, and PLC control allows for easy forward rotation for bag breaking and reverse rotation for releasing tangled materials.

Application areas

Municipal Waste Management: Opening and emptying household waste bags for sorting and recycling.

Industrial Waste Processing: Handling large volumes of bagged industrial waste, such as packaging materials and production scraps.

Recycling Facilities: Preparing bagged recyclables for further processing and separation.

Composting Operations: Opening bags of organic waste for composting processes.

Hazardous Waste Management: Safely opening and processing bags of hazardous materials to ensure proper disposal.

Bag opener machines are commonly used as the first processing step in a turnkey MSW sorting plant. Their primary function is to open waste bags without excessive shredding, allowing downstream sorting equipment to operate more efficiently.

In integrated MSW sorting solutions, bag openers are selected based on waste characteristics, throughput requirements, and plant layout, ensuring smooth material flow and improved sorting performance throughout the entire system.

Working Principle Of the Bag Opener

Through the rotating movement between the rotating movable knife and the fixed knife, a working gap is used to ensure that the rotating knife does not collide with the fixed knife, and the bagged garbage is broken to achieve the effect of separating the garbage from the plastic bag. When the material is too large, the force of the fixed knife changes. When the external force is greater than the spring thrust, the gap between the fixed knife and the movable knife will increase accordingly to ensure normal work
