Description

Technical Field

[0001] This utility model relates to the field of packaging box blister production technology, and in particular to a packaging box blister device. Background Technology

[0002] Blister packaging boxes are lightweight packaging containers made from thermoplastic sheets such as PVC, PET, and PP. These sheets are softened by heating and then vacuum-formed onto a mold surface. The production process includes mold making, sheet heating and softening, vacuum forming, and subsequent die-cutting and trimming. It features low mold costs and a short production cycle, making it particularly suitable for customized packaging needs of irregularly shaped products.

[0003] After the packaging box is vacuum-formed, it is usually integrated with the sheet material. Therefore, it is necessary to cut the packaging box from the sheet material. However, the current packaging box forming and cutting work is usually carried out in two separate processes, making it difficult to perform continuous forming and cutting processing, which greatly reduces the production efficiency of packaging boxes.
