Description

Technical Field

[0001] The utility model relates to the technical field of nailers, in particular to a cardboard nailer. Background Art

[0002] Packaging cartons are mostly assembled from multiple cardboard sheets. During the production process of cardboard sheets for some larger-sized packaging boxes, multiple cardboard sheets usually need to be spliced together. At this time, a nailer is required to nail and splice multiple cardboard sheets.

[0003] In the prior art, when nailing cardboard, it is mostly that workers hold the nailer for nailing and nail the stacked cardboard sheets to complete the splicing of the cardboard. However, during the actual nailing process, the workers need to move the cardboard for stacking. During the nailing process, if the cardboard is large, multiple nails need to be driven at the stacking position of the cardboard. During the nailing process by the workers, the number of nails and the spacing cannot be accurately controlled, and it is also easy to touch the outer cardboard, resulting in skewed nailing. The quality of nailing and splicing of the overall cardboard needs to be improved. Summary of the Utility Model

[0004] In order to improve the quality of nailing and splicing of cardboard, the present application provides a cardboard nailer.

[0005] The cardboard nailer provided by the present application adopts the following technical solutions:

[0006] A cardboard nailer includes a base and a nail head. The base is provided with a first belt conveyor for transporting cardboard. A first bracket is slidably arranged on the base.
