[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the present invention, a positioning mechanism for printing packaging boxes includes a support platform 1 and a screen 6. A guide rod 2 protruding upwards is fixed at the four corners of the top of the support platform 1. A sliding ear 3 is slidably connected to the outer periphery of the guide rod 2. One end of the sliding ear 3 is integrally formed with a first connecting plate 4. Two connecting plates 5, connected to the first connecting plate 4, are integrally formed at both ends of the edge portion of the screen 6. A handle 8 is fixedly installed at the front end of the edge portion of the screen 6. Four sets of rollers 7 are provided at the top of the support platform 1. The rollers 7 are connected to the support platform 1 via a sliding assembly. A rotation mechanism for driving the sliding assembly to move synchronously is installed at the bottom of the support platform 1.

[0018] In this embodiment: First, based on the width of the packaging box, the rotating mechanism drives the sliding component to slide, which in turn drives the rollers 7 to move until the width of the symmetrical rollers 7 is equal to the width of the packaging box. Then, the screen 6 is lifted upward by the handle 8. The screen 6 drives the sliding ear 3 to move upward along the outer wall of the guide rod 2 through the first connecting plate 4 and the second connecting plate 5. Then, the packaging box is placed on the top of the support platform 1. At this time, the four sets of rollers 7 limit the two ends of the packaging box. When pushing the packaging box, the packaging box can only move axially to avoid deviation during the movement of the packaging box until the top surface of the packaging box is pushed directly under the screen 6. Then, the force applied to the handle 8 is removed, and the bottom end of the screen 6 contacts the top end of the packaging box. Then, the printing operation can be performed.

[0019] It should be noted that when printing on packaging boxes of different sizes, the bolts connecting the No. 1 connecting plate 4 and the No. 2 connecting plate 5 can be removed, and then the screen printing plates of different sizes can be replaced.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The rotating mechanism includes a worm gear 16 rotatably mounted on the bottom of the support platform 1 via a bracket. One end of the worm gear 16 is integrally formed with an outwardly extending crank handle 15. A worm wheel 14 meshes with the outer periphery of the worm gear 16. One end of the crank handle 15 has a "Z" shaped structure.

[0021] In this embodiment: when adjusting the distance between the left and right sets of rollers 7, the crank handle 15 is turned, the crank handle 15 rotates and drives the worm gear 16 to rotate, the worm gear 16 rotates the worm wheel 14 to rotate, and the worm wheel 14 can drive the sliding component to move.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The sliding assembly includes a gear 13 coaxially connected to the bottom of the worm gear 14. Both sides of the outer periphery of the gear 13 are meshed with racks 12. The top of each rack 12 is fixedly connected to a support plate 11. The sliding assembly also includes a sliding column 10 rotatably installed at both ends inside the support plate 11. The top of the sliding column 10 extends through to the top of the support platform 1 and is fixedly connected to the bottom of the roller 7.

[0023] In this embodiment: when the worm gear 14 rotates, the rotation of the worm gear 14 can synchronously drive the gear 13 to rotate. When the gear 13 rotates, it drives the two racks 12 to move towards each other or in opposite directions. The racks 12 drive the support plate 11 connected to them to move synchronously. The support plate 11 can then drive the two sets of rollers 7 above it to move synchronously through the sliding column 10, thereby realizing the spacing between the left and right rollers 7 to meet the adjustment purpose, and thus positioning the packaging boxes of different widths left and right.

[0024] Please refer to this carefully. Figure 1 The support platform 1 has a groove 9 inside for the sliding column 10 to slide, and the bottom end of the roller 7 is in contact with the top end of the support platform 1.

[0025] In this embodiment: during the movement of the sliding column 10, the sliding column 10 can move along the slot 9.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
