Description

Technical Field

[0001] The utility model relates to the technical field of edge trimming machines, in particular to an edge trimming machine for processing a packaging box. Background Art

[0002] After injection molding, the outer wall of the plastic packaging box is prone to have excess convex edges. In the prior art, a fully automatic hydraulic trimming machine is used to cut the convex edges of the plastic packaging box. That is, the trimming knife set there is adjusted to a position in contact with the outer wall of the plastic packaging box, the cutting knife is controlled to rotate, and at the same time, the device supporting the plastic packaging box is controlled to rotate, so as to evenly trim the outer wall of the plastic packaging box.

[0003] However, when trimming a plastic packaging box or a plastic packaging box with an irregular shape, the convex edges at different positions of the plastic packaging box cannot be trimmed simultaneously.

[0004] The main reason for the above problems is that the existing fully automatic hydraulic trimming machine is only equipped with one set of trimming knives for trimming operations. If multiple sets of trimming knives are required, a corresponding number of drive devices are required for control, which may easily cause unnecessary waste of energy. In addition, for irregular plastic packaging boxes molded by injection, the convex edges at different positions are at different distances from the trimming knives. Therefore, multiple sets of trimming knives in coaxial positions cannot achieve simultaneous cutting of the convex edges of the outer wall of the irregular plastic packaging box, which has great limitations. To address the above problems, we propose a packaging box processing and trimming machine. Utility Model Content
