Title:
SUCTION CUP FOR USE IN DOUBLE-LAYER BAG PRODUCTION, SUCTION CUP ASSEMBLY, AND MANUFACTURING APPARATUS FOR DOUBLE-LAYER BAG
Document Type and Number:
WIPO Patent Application WO/2024/051505
Kind Code:
A1
Abstract:
Provided in the present application are a suction cup for use in double-layer bag production, a suction cup assembly, and a manufacturing apparatus for a double-layer bag. The suction cup for use in double-layer bag production comprises a suction cup body, a carrying component and a buffer pad, wherein the suction cup body has a cavity located on the inside and a first contact surface located on the outside, the first contact surface is configured to come into contact with an outer surface of a double-layer bag, and a portion of the first contact surface is recessed in the heightwise direction of the suction cup body to form a positioning recess; the carrying component can be detachably arranged in the positioning recess; the buffer pad is connected to the carrying component, the surface of the buffer pad facing away from the carrying component forms a second contact surface that is configured to come into contact with the outer surface of the double-layer bag, and the buffer pad matches with the positioning recess; and first suction holes for suctioning the outer surface of the double-layer bag are formed in the first contact surface and/or the second contact surface, and the first suction holes are in communication with the cavity. By means of the present application, the efficiency of removing and replacing the buffer pad can be improved, thereby conducive to reducing the impact on the production efficiency due to the removal and replacement of the buffer pad.
