Description

technical field

[0001] The invention relates to a packaging box, a corrugated paper semi-finished board and a crease line wheel assembly, in particular to a packaging box, a corrugated paper semi-finished board and a machine for forming crease lines on a corrugated paper semi-finished board Crease wire wheel. Background technique

[0002] Conventionally, boxes made of corrugated cardboard have generally been used for packaging various products. When storing heavy objects in such a packing box and storing them in a relatively high-humidity state, due to the weight of the packing box stacked on the top, such as Figure 26 Shown is a "waist bulge" in which the sides bulge outward. The "lumbar bulge" mentioned here includes not only the case of bulging outward, but also the case of indenting inward or both concave and bulging to form an S-shaped deformation. This occurs because the upper and lower sides of the packing box 501a are distorted when weight is applied from above, a...
