TECHNICAL FIELD

[0002] A packaging box generally comprises a paperboard carton and a face paper pasted on the outer surface of the paperboard carton. The paperboard carton is formed by a corresponding corner pasting machine, and the face paper is automatically pasted on the outer surface of the paperboard carton by a forming machine after being glued. In the process of pasting the face paper on the outer surface of the paperboard carton, the side edge of the face paper needs to be bent and pasted on the side wall of the paperboard carton, which is called ear folding.

[0003] In the prior art, a Chinese patent document with the number 202421334527.3 discloses a push-ear structure suitable for different sizes and a packaging box forming device. The push-ear structure comprises a push-ear assembly and a push-ear adjusting assembly. The push-ear adjusting assembly comprises an adjusting column, a height adjusting piece, a front and rear adjusting piece, and a push-ear connecting piece. The front and rear adjusting piece is connected to the adjusting column through the height adjusting piece.

The spacing between the two left push-ear mechanisms, the spacing between the two right push-ear mechanisms, and the spacing between the left and right push-ear mechanisms are adjusted by the first and second adjustment mechanisms to accommodate packaging boxes of different sizes.

During the process of the push-ear plate pushing the side edge of the outer paper, if there is pressure between the push-ear plate and the side wall of the box body (e.g., slight interference due to dimensional errors), the buffer module acts as a buffer, ensuring that the push-ear plate presses the side edge of the outer paper tightly against the side wall of the box body and making the movement of the push-ear plate smoother, thus ensuring the quality of the ear-folding to a certain extent. Furthermore, the angle adjustment component is adjustable, thereby adjusting the angle of the ear-folding plate to accommodate the ear-folding process on the sides of the face paper of various irregularly shaped boxes. The ear-folding plate of this invention provides cushioning, resulting in smoother movement, better folding quality, and an adjustable angle, offering good adaptability. It can fold ears not only for boxes of different sizes but also for irregularly shaped boxes. Attached Figure Description
