Description

Technical Field

[0001] The utility model relates to the technical field of container cargo packaging and transportation, in particular to an IBC liner bag unloading tool. Background Art

[0002] IBC stands for Intermediate Bulk Container, generally called container barrel. It is usually square and needs to be used with IBC liner bags made of plastic film. Its specifications are 820L, 1000L, and 1250L. IBC container barrels can be reused many times, and the advantages reflected in filling, storage and transportation can significantly reduce costs. In order to prevent leakage during transportation, although this IBC liner bag is preset with a valve interface for unloading, the valve interface is welded on the side wall of the bag body by heat sealing, and the interface itself is not connected to the bag body. When unloading, after opening the cover on the valve interface, it is necessary to use a special opener to pierce the plastic film inside the valve interface, connect the valve interface with the bag body, and then connect the unloading valve and the unloading container, and transfer the goods in the IBC liner bag to the unloading container through the unloading valve. In this way, leakage is likely to occur at the moment when the opener pierces the plastic film inside the valve interface to the moment when the unloading valve is connected, resulting in a small amount of cargo loss. For example, Chinese patent application 201110074091X discloses "A Rotary Bag Opener", with publication number CN102689718A, which includes an upper cover and an annular base that can rotate and cooperate with each other, and an annular rotary cutter. The rotary cutter is pulled by an elastic member and is located in the circular space of the base. It is linked to the upper cover. The rotary cutter rotates with the upper cover, and its blade extends from the bottom of the base. A sticky body is provided on the bottom surface of the base. The opener can be directly bonded to the packaging bag. After rotating the upper cover, a hole can be cut in the packaging bag, and the product in the packaging bag can be poured out through the hole. However, this opener can only play the role of opening the plastic packaging bag and pouring out the goods in the bag. When used for IBC liner bags with larger volumes, it is still impossible to achieve leak-free docking between the opening and the transit goods. Summary of the invention

[0003] The utility model aims to provide an IBC liner bag unloading tool which has a simple structure, is easy to use and can realize the docking of goods without leakage.
