Description

Technical Field

[0001] The utility model relates to the technical field of all-in-one gluing and nailing machines, in particular to a paper feeding structure of an all-in-one gluing and nailing machine. Background Art

[0002] As we all know, in the existing carton packaging and related industries, the stability and efficiency of the paper feeding structure of the all-in-one gluing and nailing machine, as an automated equipment integrating gluing and fixing functions, has a vital impact on the smooth operation of the entire production line and product quality. Traditional paper feeding structures often have problems such as cardboard stacking, uneven feeding, and paper jams. These problems not only reduce production efficiency, but may also lead to a decline in product quality, increase scrap rate, and thus increase production costs.

[0003] Specifically, traditional paper feeding structures mostly use simple mechanical pushing or vibration conveying methods, which make it difficult to accurately control the conveying speed and position of the cardboard, and it is easy for cardboard to stack or shift during the conveying process. In addition, for cardboards of different sizes and thicknesses, the traditional paper feeding structure has poor adaptability and requires frequent adjustment or replacement of parts, which increases the difficulty of operation and downtime.
