Description

Technical Field

[0001] The utility model relates to the technical field of creasing equipment, in particular to a shock absorbing structure for a single creasing line for producing packaging cartons. Background Art

[0002] Packaging cartons are used to package many products. Most of the existing packaging cartons are made of corrugated cardboard. The corrugated line is a production line used to produce corrugated cardboard. When producing single-corrugated cardboard, it needs to be indented to facilitate the subsequent folding of the packaging cartons.

[0003] In order to improve the accuracy of creasing corrugated cardboard, the prior art has made many improvements to cardboard creasing equipment. For example, patent publication number CN215620296U discloses a shock-absorbing structure for a single-wafer creasing line for producing packaging cartons, comprising a workbench, wherein support plates are fixedly connected to the left and right sides of the upper end of the workbench, damping blocks are fixedly connected to the front and rear ends of the inner side of the support plate, and shock-absorbing blocks are fixedly connected to the upper and lower ends of the inner side of the support plate. A shock-absorbing spring is provided inside the shock-absorbing block, and a gasket is slidably connected to the inner side of the shock-absorbing block. In this utility model, by providing the shock-absorbing block, shock-absorbing spring, gasket and damping block, when the equipment is running, the support rod slides in the damping block in the support plate, and the inner side of the damping is provided with an arc-shaped setting, and the damping block is made of a flexible material, which can improve the damping effect between the support rod and the support rod, reduce the running speed, and when the support rod contacts the gasket, the gasket squeezes the shock-absorbing spring and the shock-absorbing block is deformed. This arrangement improves the shock-absorbing effect of the equipment and reduces the service life of the parts in the equipment.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, a combination of shock-absorbing blocks, shock-absorbing springs, gaskets and damping blocks is used to achieve a shock-absorbing effect on the creasing equipment. The above-mentioned comparative document performs a creasing treatment on the corrugated cardboard by moving the folding knife downward, while in the prior art, the efficiency of using a folding knife that moves up and down to creasing the corrugated cardboard is relatively slow. Many prior arts use roller-type creasing rollers to creasing the corrugated cardboard, while the shock-absorbing structure in the above-mentioned comparative document is not suitable for roller-type creasing of corrugated cardboard. Therefore, this field urgently needs to improve the shock-absorbing structure for the single-corrugated line for producing packaging cartons, so as to solve the defects of the prior art. Utility Model Content
