[0002] Paper box packaging is largely used to promote and beautify products with its exquisite shape and decoration to improve the competitiveness of products. Since the shape and structural design of paper boxes are often determined by the shape characteristics of the packaged goods, there are many styles and types, including rectangular, square, polygonal, special-shaped paper boxes, cylindrical, etc., but their manufacturing process is basically the same, that is, selecting materials-designing icons-making templates-die cutting and stamping-joining into boxes.

[0003] After die-cutting and stamping, the waste generated by die-cutting needs to be cleared to facilitate the next process. Currently, the waste on the edge of the paper can only be cleared semi-automatically or manually, which is slow, requires a huge space for operation, has a poor working environment, is polluted by dust and gas, has high labor intensity, and has high labor costs. In addition, with the development requirements of packaging products, the corresponding die-cutting layout is becoming more and more complicated, and the difficulty of semi-automatic and manual waste cleaning is increasing, and the waste cleaning effect is becoming more and more difficult to guarantee.

[0004] At present, there are also some waste cleaning devices that can clean cardboard and improve the efficiency of waste cleaning. Most of the existing waste cleaning devices use rollers to rotate the cleaning points to clean the waste. During the waste cleaning process, when cleaning cardboard with a tongue structure, the roller is easy to touch the position of the tongue, causing it to tilt, affecting subsequent processes such as cleaning and bonding, thereby affecting the quality of the product.
