Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of corrugated paper corner punching machines, in particular to a feeding limiting mechanism of the corrugated paper corner punching machines. Background Art
[0002] In corrugated paper, "pit" refers to the wavy or concave-convex paper core structure inside, which is the key part of corrugated paper in providing cushioning and supporting force.
[0003] In the process of processing corrugated paper, it is usually necessary to use a pit forming and cornering machine to stick tape on the four sides of the pit to fix it into shape. During operation, a material-taking suction cup is used to take away the topmost pit and put it on the work station of the cornering machine. Due to the shaking of the pit forming and cornering machine during operation, it is easy to cause the position of the remaining pits to shift, so that the pit position will be skewed when the material-taking suction cup takes the material next time, resulting in uneven box mouth of the finished product and substandard product quality.
