Problems solved by technology

[0002] The existing wrapping paper cutting step is usually to cut the wrapping paper into a suitable rectangular sheet, and then use a cutting device to cut the rectangular sheet into various packaging shapes (for example: the shape of a shoe box). This cutting method not only The packaging cardboard needs to be cut into rectangular pieces of paper first, and manual feeding is required. Therefore, the production efficiency is low. At the same time, due to the defect of poor precision in manual feeding, in order to ensure the cutting yield, the general practice is to Leave enough margin on the edge of the paper sheet (that is, the area of ​​the rectangular paper sheet will be larger than the effective die area) for subsequent trimming, thus increasing the production cost;
[0003] Not only that, in order to improve the air-dispersing effect of the current packaging box, holes are usually punched on the packaging box, but the existing step is generally carried out after the packaging box is formed, and after the packaging box is formed, in order to avoid damage to the packaging box, This process is generally done manually, therefore, there is a disadvantage of low efficiency
