Description

Technical Field

[0001] This utility model relates to the field of stacking device technology, specifically a lifting device for stacking corrugated cardboard. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is a multi-layered adhesive. It consists of at least one corrugated core paper layer and one cardboard layer. After production, corrugated cardboard needs to be stacked, which requires the use of stacking equipment.

[0003] To facilitate the stacking of corrugated cardboard, existing technologies have made numerous improvements to lifting devices for corrugated cardboard stacking. For example, patent publication number CN217626738U discloses a lifting device for corrugated cardboard stacking, which includes a frame and a lifting platform mounted on the frame. The lifting platform is equipped with a support plate for placing corrugated cardboard. The frame is equipped with multiple limiting components for limiting the position of the corrugated cardboard on the support plate. Each limiting component includes a limiting plate and a pushing member that moves the limiting plate. The pushing member is mounted on the frame, and the limiting plate abuts against the side of the corrugated cardboard stacked on the support plate. This application effectively reduces the offset of the corrugated cardboard on the support plate.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the aforementioned comparative documents, cardboard is stacked on a support plate, and the corrugated cardboard is lifted and stacked using a lifting platform that can move up and down. However, in reality, corrugated cardboard is produced by gluing the face sheet and the core sheet together, and the edges of the cardboard may curl after production. After the corrugated cardboard is produced, it needs to be shaped. However, the aforementioned comparative documents do not have the function of shaping the cardboard, requiring subsequent processing, which reduces the efficiency of stacking corrugated cardboard. Therefore, there is an urgent need in the art to improve the lifting device for stacking corrugated cardboard to overcome the shortcomings of the prior art. Utility Model Content
