[0002] In the modern packaging industry, the printing process of packaging boxes is very important. It not only affects the appearance quality of the packaging boxes, but also directly affects the market image of the product and the purchasing experience of consumers. In particular, hard packaging boxes are widely used in gift packaging, high-end product packaging and other fields due to their durability and high-end texture.

[0003] The production of rigid packaging boxes mainly includes two core processes: printing and assembly. However, if the pattern is printed on the flat surface of the rigid material first and then assembled, the precision differences during the assembly process may cause the printed pattern to be misaligned or deformed on the assembled packaging box, thus affecting the overall image and market value of the product.

[0004] Therefore, it is particularly urgent to design a device that can perform efficient and high-quality printing on the hard packaging boxes that have been processed and formed. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Referring to Figure 1 , the present utility model provides a packaging box printing device, which includes a frame 1. Above the frame 1, multiple belt conveyors 2 are installed. A number of printing mechanisms 8 are arranged on the multiple belt conveyors 2. Below the printing mechanism 8, a lifting mechanism 7 is installed. The lifting mechanism 7 lifts the packaging box on the multiple belt conveyors 2 to facilitate the printing mechanism 8 to print the corresponding surface. A flipping mechanism 4 is provided between the two printing mechanisms 8. The main function of this mechanism is to flip the packaging box 90° during the transfer process between the two printing mechanisms 8 so as to continuously print different surfaces of it.

[0019] A rectifying mechanism is provided at the feeding port of each printing mechanism 8; the main function of this mechanism is to adjust the position and posture of the packaging box before it enters the printing area to ensure that the packaging box enters the printing area in the correct manner. Specifically, the rectifying mechanism includes a rectifying bracket 3, an adjusting nut 9 and a guiding plate 5. The rectifying bracket 3 is installed on the frame. The adjusting nut 9 is installed on the rectifying bracket 3 by threaded connection. The guiding plate 5 is connected to the adjusting nut 9. One end of the guiding plate 5 away from the printing mechanism 8 extends to the outside of the multiple belt conveyors 2 to facilitate the packaging box to enter between the two guiding plates 5. By adjusting the adjusting nut 9, the position of the guiding plate 5 can be changed, thereby guiding the packaging box to enter the printing area in the correct posture.

[0020] Referring to Figure 2 , the flipping mechanism 4 includes a flipping motor 401, a speed reducer 402, a flipping shaft 403 and flipping support blocks 404. The speed reducer 402 is connected to the output shaft of the flipping motor 401. The output end of the speed reducer 402 is connected to the flipping shaft 403 to transmit the decelerated power to the flipping shaft. A number of flipping support blocks 404 are provided on the flipping shaft 403. The cross-section of the flipping support blocks 404 is square and is aligned with the gap of the multiple belt conveyors 2. Flipping support rods 405 are provided on the side surfaces of the flipping support blocks 404; when the flipping motor 401 is started, the flipping shaft 403 is driven to rotate through the speed reducer 402, and the flipping support blocks 404 rotate accordingly to flip the packaging box that has completed printing on one side so as to perform printing on the other side.

[0021] Referring to Figure 3, the lifting mechanism 7 includes a support platform 701. Above the support platform 701, there is a lifting platform 703. A number of guide columns 702 are arranged on the lifting platform 703. The lower ends of the guide columns 702 penetrate through the support platform 701 to ensure the stable lifting of the lifting platform 703. A lifting cylinder 704 is arranged on the support platform 701. The piston rod of the lifting cylinder 704 is connected to the support platform 701. By controlling the expansion and contraction of the lifting cylinder 704, the lifting and lowering of the lifting platform 703 are realized.

[0022] The lifting platform 703 is composed of a translation slide rail 705, a fixed support 706, and two moving supports 707. The fixed support 706 is fixedly arranged on the lifting platform 703. The two moving supports 707 are located on the translation slide rail 705 on both sides of the fixed support 706 and can move horizontally along the slide rail. A push plate 710 and a stepping motor 708 are arranged on the fixed support 706. A screw rod 709 is arranged on the output shaft of the stepping motor 708. The push plate 710 is slidably connected to the fixed support 706 and is in threaded cooperation with the screw rod 709. When the stepping motor 708 rotates, the push plate 710 moves along the length direction of the fixed support 706, driving the connecting rod 711 rotatably connected to it, thereby pushing the moving support 707 to move outward or inward, realizing the adjustment of the distance between the fixed support 706 and the two moving supports 707 to adapt to packaging boxes of different sizes. In actual application, the gaps between the fixed support 706 and the two moving supports 707 are exactly opposite to those of the multi - belt conveyor 2.

[0023] Lifting support plates 712 are arranged at the tops of the fixed support 706 and the moving support 707. A number of suction cups 713 are arrayed along the length direction of the lifting support plate 712. The suction cups 713 are used to adsorb and fix the packaging box to ensure stability during the printing process.
