[0002] Blister packaging boxes are made through the blister process. The main principle of this process is to heat and soften the flat plastic hard sheet, then use vacuum adsorption on the mold surface, and then cool it to form. The raw materials of blister packaging boxes mainly include PVC, PS, PP, PET, PETG and other plastic materials. These materials have good plasticity and durability and are suitable for making packaging boxes. During the production process of blister packaging boxes, there will be gaps between the molds, resulting in some burrs on the produced packaging boxes. At this time, the packaging box burr processing device will be used.

[0003] However, in actual applications, when the existing packaging box burr processing device is used, since the packaging box is usually made of plastic material and has poor hardness, when cutting the burr, the cutting surface lacks support, resulting in irregular jagged burrs formed on the cut edge, which not only affects the overall aesthetics of the product, but also may have an adverse effect on the packaging quality. In addition, the packaging box is easily skewed during transportation, resulting in an uneven cut end surface of the packaging box. Based on the above problems, the present application provides a packaging box burr processing device.
