Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically to a clamping mechanism for a powder-liquid dual-chamber bag. Background Technology

[0002] In the existing technology, after the powder cavity is cut with an opening, it is mounted on a fixture to open the opening at the next station. When opening the powder cavity opening, it mainly relies on movable suction cups spaced apart on both sides of the fixture. The suction cups move closer to the powder cavity and stick to the film used to construct the powder cavity on both sides. Then the suction cups move away from the powder cavity and open the opening located at the top of the cavity. However, in this process, it mainly relies on the pulling force of the movable suction cups to open the fixture. The suction force of the suction cups and the pulling force of the suction cups to pull the film outward may interfere with the force of the fixture, which may cause the suction cups to detach from the film, making it impossible to complete the opening of the powder cavity. This affects the opening process of the powder cavity and the entire production process of the product. Utility Model Content
