Since the ears at the opening of the box body are flush, using the existing bending mechanism will squeeze and damage the adjacent ears, affecting the appearance of the packaging box. Summary of the Utility Model

[0003] The purpose of the embodiments of this application is to provide a packaging box processing device to solve the technical problem that the bending mechanism in the prior art will squeeze and damage the adjacent ears.

[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide a packaging box processing device for hemming the ears of a box body, including:

The hemming mechanism 30 is used to hem the ear portion 91 of the box body 90. The hemming mechanism 30 includes a first pressing plate 31, a second pressing plate 32, a first driver 33, a first support 34, a second driver 35, and a second support 36; the first pressing plate 31 is used to push against the ear portion 91 of the box body 90 so that the ear portion 91 is bent inwardly towards the box body 90; the second pressing plate 32 is used to abut against the outer side of the box body 90 and adjacent to the bending line 92 of the ear portion 91 (please refer to Figure 1) position; the first driver 33 is used to drive the first pressing plate 31 and the second pressing plate 32 to cooperate to clamp the position of the ear part 91 and the box body 90 adjacent to the folding line 92. The power output end of the first driver 33 is connected to the first pressing plate 31; when the first driver 33 drives the first pressing plate 31 away from the second pressing plate 32, the first pressing plate 31 and the second pressing plate 32 are displaced along the width direction of the second pressing plate 32 (which can be understood as the length direction of the box body 90); the first support 34 supports the first driver 33 and the second pressing plate 32; the second driver 35 is used to drive the first support 34 to approach or move away from the box body 90, and the power output end of the second driver 35 is connected to the first support 34; the second support 36 supports the second driver 35. When the second driver 35 drives the first support 34 to approach the box body 90, the first pressing plate 31 and the second pressing plate 32 are respectively located on both sides of the folding line 92 (i.e., displaced along the length direction of the box body 90). The first pressing plate 31 first contacts the ear part 91 and pushes the ear part 91 to bend towards the inner side of the box body 90 along the folding line 92 until the second pressing plate 32 abuts against the surface of the box body 90; at this time, the first driver 33 drives the first pressing plate 31 to move towards the direction close to the second pressing plate 32, and the first pressing plate 31 drives the ear part 91 to fold until it is tightly attached to the inner wall of the box body 90, so that the corresponding position of the ear part 91 and the box body 90 is clamped by the first pressing plate 31 and the second pressing plate 32.

The second pusher 2144 is installed on the other side of the sliding seat 213, and the power output end of the second pusher 2144 is connected to the second clamping plate 2143. The second pusher 2144 is used to drive the second clamping plate 2143 to approach the first clamping plate 2141. In this way, the box body 90 can be clamped or released. The first clamping plate 2141 and the second clamping plate 2143 can be vacuum suction plates, so that the box body 90 can be prevented from sliding.

[0071] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
