Description

Technical Field

[0001] The present application relates to the technical field of edge trimming of blister boxes, and in particular to an edge trimming tool for finishing blister boxes. Background Art

[0002] Blister is a plastic processing technology. The main principle is to heat and soften the flat plastic hard sheet, then use vacuum adsorption to the mold surface, and then cool it to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. Blister box in a broad sense refers to all bubble shells, and in a narrow sense, it is just a type of bubble shell. During the production process, the hot-melt plastic needs to be molded. The edge of the molded blister box will produce overflow or burrs, so the blister box needs to be sheared.

[0003] After searching, the patent number CN220840406U discloses a trimming device for processing blister boxes, wherein an L-shaped support assembly is provided on one side of the upper end of the base, a first T-limiting groove is provided in the middle of the upper end of the base, a bottom plate is provided in the middle of the upper end of the base, a first T-shaped limiting portion is provided in the middle of the lower end of the bottom plate, a positioning mold is provided in the middle of the upper end of the bottom plate, a pressing plate is provided in the middle of the inside of the ring cutting frame, a triangular cross-section ring cutting knife is provided at the lower end of the ring cutting frame, a connecting assembly is provided in the middle of the upper end of the ring cutting frame, a limiting pin is provided on the connecting assembly, and a hydraulic rod is provided in the middle between the upper end of the connecting assembly and the L-shaped support assembly. In this patent, the ring cutting frame slides into the second T-shaped limiting groove on the connecting assembly for limiting, and the ring cutting frame is closed downward with the positioning mold by driving the hydraulic rod. The lower end of the ring cutting frame is provided with a triangular cross-section ring cutting knife, which can trim the four sides of the blister box at the same time.
