[0002] In the process of packaging box printing production, edge printing work is usually used to improve the aesthetics and recognition of product packaging, and can print patterns on the edges or sides of the packaging box, enhancing the market competitiveness of the product. The printed patterns can be text, images, or a combination of both, and are widely used in the printing of packaging boxes in various industries such as food, beverage, cosmetics, medicine, and electronic products.

[0003] For the current field of packaging box processing, the present application has formulated corresponding solutions for the following existing problems:

[0004] In the process of packaging box printing, the packaging box usually undergoes multiple transfer operations and then cooperates with the printing equipment for printing work.

[0039] The working principle of a packaging box side pattern printing device of the present utility model:

[0040] When the packaging box side pattern printing device is in use, the packaging box is placed into the guiding channel formed by the symmetrically distributed side guiding and aligning mechanisms. The guiding wheel and the auxiliary wheels provided in the swing guiding mechanism arranged in an elastic and inclined manner are used to guide the packaging box to move. The adjustable swing frame can be set according to the width of the packaging box. The symmetrically distributed guiding and swinging structures enable the packaging box to be conveyed in the middle of the conveying device. The conveyor belt in the conveying device conveys the packaging box. When the packaging box moves into the working range of the printing device, the printing device will print the two side edges of the packaging box. The packaging box is sent by the conveying device to the next process;

[0041] When the packaging box contacts with the side guiding mechanism, the guiding wheels first contact with the side of the packaging box. The driving motor drives the guiding wheels to rotate, and the packaging box is guided and aligned by the guiding wheels distributed on both sides. The guiding wheels and auxiliary wheels with a certain inclination will apply a continuous downward pressure to the packaging box during transportation, preventing the packaging box from bouncing when contacting the conveyor belt and ensuring the consistency of the posture of the packaging box in subsequent transportation links.

[0042] When the packaging box contacts with the guiding wheels, it will push the swinging guiding structure that is inclined inward in a clamping shape to both sides. The swinging guiding structure performs an arc swinging operation, and the torsion spring provided below the swinging guiding structure realizes the elastic reset effect, enabling the guiding wheels and auxiliary wheels in the swinging guiding structure to be in close contact with the outer surface of the packaging box and ensuring the guiding effect.

[0043] When it is necessary to adjust the elasticity and clamping range of the swinging guiding structure, the swinging range of the swinging guiding structure is restricted by adjusting the installation position of the limit posts.

[0044] When it is necessary to adjust the sliding position of the swinging guiding structure, the driving motor in the pushing seat pushes the moving seat to move, thereby adjusting the working position of the swinging guiding structure installed above the moving seat.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
