As consumer demands for product packaging continue to rise, the precision, efficiency, and cost control of color box printing have become key focuses for the industry.

[0003] In the process of color box printing, the color box is transported to the bottom of the printing unit by the feeding mechanism. Since it is mainly completed by the conveyor belt, the color box is prone to movement during the printing process, which leads to the color box printing being skewed and has certain defects. To address this, we propose a color box printing device. Utility Model Content

The worktable serves as the supporting base of the apparatus. The feeding mechanism is located on top of the worktable and is used to feed the color box into the printing position. The support mechanism is located on top of the worktable, and the feeding mechanism is located directly below the support mechanism. The adjustment mechanism is installed on the inner top of the support mechanism, and the laser printhead is installed at the bottom of the adjustment mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A printing apparatus for color boxes includes a worktable 1, a feeding mechanism 2, a support mechanism 3, an adjustment mechanism 4, and a laser printhead 5. The worktable 1 serves as the supporting base of the apparatus. The feeding mechanism 2 is located on top of the worktable 1 and is used to feed the color box into the printing position. The support mechanism 3 is located on top of the worktable 1, and the feeding mechanism 2 is located directly below the support mechanism 3. The adjustment mechanism 4 is installed on the inner top of the support mechanism 3, and the laser printhead 5 is installed at the bottom of the adjustment mechanism 4. The support mechanism 3 is used to adjust the height of the laser printhead 5, and the adjustment mechanism 4 is used to adjust the horizontal position of the laser printhead 5.

[0023] In one embodiment, the feeding mechanism 2 includes a base 21, a first motor 22, a first threaded post 23, a first slider 24, a feeding plate 25, an adjusting rod 26, a second slider 27, and a limiting plate 28. The first motor 22 is mounted on the side of the base 21. The output shaft of the first motor 22 is inserted into the interior of the base 21 and connected to the first threaded post 23. The first slider 24 is threadedly connected to the first threaded post 23. The top of the first slider 24 is connected to the feeding plate 25. The adjusting rod 26 is installed inside the feeding plate 25. The two ends of the adjusting rod 26 are threadedly connected to the second slider 27. The limiting plate 28 is mounted on the top of the second slider 27. The first slider 24 is slidably connected to the interior of the base 21, and the second slider 27 is slidably connected to the feeding plate 25. The threads at both ends of the adjusting rod 26 have opposite directions of rotation. The feeding mechanism, support mechanism, and adjusting mechanism are combined with the laser print head. In terms of printing precision, the traditional conveyor belt feeding method that easily causes the color box to move is abandoned. The feeding mechanism drives the first threaded column to rotate through the first motor, which drives the first slider and the feeding plate to move and feed precisely. The adjustment rod and the second slider adjust the distance between the limit plate, which stabilizes and restricts the position of the color box, effectively avoids printing skew, and ensures accurate printing of patterns and text.

[0024] In one embodiment, the support mechanism 3 includes a support plate 31, a second threaded post 32, a first threaded sleeve 33, a first bevel gear 34, a first housing 35, a second motor 36, a second bevel gear 38, and a rotating shaft 37. The second threaded post 32 is mounted on the support plate 31, and the first threaded sleeve 33 is threadedly connected to the second threaded post 32. The first housing 35 is rotatably mounted on the first threaded sleeve 33, and the first bevel gear 34 is mounted on the first threaded sleeve 33. The second motor 36 is mounted on the first housing 35, and the output shaft of the second motor 36 is connected to the rotating shaft 37. The second bevel gear 38 is mounted on the rotating shaft 37. The first bevel gear 34 and the second bevel gear 38 are meshed and driven. The two first bevel gears 34 are installed in opposite directions, and the two second bevel gears 38 are installed in opposite directions. The adjustment mechanism 4 is installed at the bottom of the first housing 35. The support mechanism uses the second motor to drive the rotating shaft, bevel gear, and threaded post to precisely adjust the height of the laser print head, adapt to the printing needs of color boxes of different thicknesses, ensure uniform and stable printing pressure, and further improve printing quality.

[0025] In one embodiment, the adjustment mechanism 4 includes a first movable frame 41, a fourth motor 42, a third threaded post 43, a third slider 44, a second movable frame 45, a fourth threaded post 46, and a drive mechanism 47. The second movable frame 45 is installed at the bottom of the first housing 35. The fourth motor 42 is installed on the first movable frame 41. The third threaded post 43 is installed inside the first movable frame 41 and connected to the output shaft of the fourth motor 42. The third slider 44 is threadedly connected to the third threaded post 43 and fixed to the second movable frame 45. The fourth threaded post 46 is installed inside the second movable frame 45. The drive mechanism 47 is installed on the fourth threaded post 46. The laser print head 5 is installed at the bottom of the drive mechanism 47. The drive mechanism 47 includes a second threaded sleeve 471 threadedly connected to a fourth threaded post 46. A third bevel gear 472 is fixedly sleeved on the second threaded sleeve 471. A second housing 473 is mounted on the second threaded sleeve 471. A third motor 474 is mounted on the side of the second housing 473. The output shaft of the third motor 474 is inserted into the interior of the second housing 473 and connected to a fourth bevel gear 475. The third bevel gear 472 and the fourth bevel gear 475 are meshed and driven. The laser print head 5 is mounted at the bottom of the second housing 473. The design of the adjustment mechanism can achieve fine adjustment of the laser print head in the horizontal direction, and can quickly position it to the ideal printing position to meet the registration requirements of complex patterns and multi-color printing.

[0026] In use, first place the color box on the feeding plate 25 of the feeding mechanism 2, rotate the adjusting rod 26. Since the threads at both ends of the adjusting rod 26 are turned in opposite directions and are threadedly connected to the second slider 27, the second slider 27 is slidably connected to the feeding plate 25. Rotating the adjusting rod 26 can cause the second sliders 27 on both sides to drive the limiting plates 28 to move towards or in opposite directions. Adjust the spacing of the limiting plates 28 to match the width of the color box and firmly clamp the color box. Start the first motor 22 of the feeding mechanism 2. Its output shaft drives the first threaded column 23 to rotate. Since the first slider 24 is threadedly connected to the first threaded column 23 and connected to the feeding plate 25, and the first slider 24 is slidably connected to the inside of the base 21, the rotation of the first threaded column 23 causes the first slider 24 to drive the feeding plate 25 to move horizontally along the base 21, transporting the color box to the printing position.

[0027] In the support mechanism 3, the second motor 36 starts, and its output shaft drives the rotating shaft 37 to rotate. The second bevel gear 38 on the rotating shaft 37 meshes with the first bevel gear 34 installed on the first threaded sleeve 33. The two first bevel gears 34 and the two second bevel gears 38 are installed in opposite directions, realizing the lifting and lowering movement of the first threaded sleeve 33 on the second threaded post 32. This, in turn, drives the entire adjustment mechanism 4 and the laser print head 5 to rise or fall, adjusting to a printing height suitable for the current carton thickness, ensuring the optimal distance and pressure between the laser print head 5 and the carton surface during printing. When the fourth motor 42 of the adjustment mechanism 4 works, it drives the third threaded post 43 to rotate. The third slider 44 is threadedly connected to the third threaded post 43 and fixed to the second movable frame 45. The rotation of the third threaded post 43 causes the third slider 44 to drive the second movable frame 45 to move horizontally, realizing the initial horizontal position adjustment. Subsequently, the third motor 474 of the drive mechanism 47 starts, and its output shaft drives the fourth bevel gear 475. When rotated, the fourth bevel gear 475 meshes with the third bevel gear 472, causing the second threaded sleeve 471 to rotate. The second threaded sleeve 471, through its threaded transmission with the fourth threaded post 46, causes the second housing 473 to drive the laser print head to move axially along the fourth threaded post 46, thereby precisely adjusting the horizontal position of the laser print head 5 and ensuring that the printed pattern is accurately printed at the designated position on the color box.

[0028] In summary, compared to existing technologies, this utility model utilizes a feeding mechanism, a support mechanism, and an adjustment mechanism in conjunction with a laser printhead. Regarding printing accuracy, it abandons the traditional conveyor belt feeding method that easily causes the color box to shift. The feeding mechanism uses a first motor to drive a first threaded column to rotate, causing the first slider and feeding plate to move precisely for feeding. This, combined with the adjustment rod and second slider, adjusts the distance between the limiting plates, firmly restricting the color box's position and effectively preventing printing skew, ensuring accurate printing of patterns and text. Simultaneously, the support mechanism uses a second motor to drive a rotating shaft, bevel gear, and threaded column transmission to precisely adjust the height of the laser printhead, adapting to the printing needs of color boxes of different thicknesses, ensuring uniform and stable printing pressure, and further improving printing quality. Furthermore, the adjustment mechanism allows for fine adjustment of the laser printhead in the horizontal direction, enabling rapid positioning to the ideal printing position and meeting the registration requirements of complex patterns and multi-color printing.

[0029] 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.
