AI Technical Summary
Existing carton ink printing machines operate in a single-sided mode, which leads to extended production cycles. Furthermore, the lack of effective limiting mechanisms in the conveyor belt area causes the cartons to easily shift laterally or tilt longitudinally during travel, resulting in printing defects such as misregistration of images and text, and uneven ink layer thickness.
The design incorporates a double-sided printing assembly with a limiting component. The carton is conveyed via a conveyor belt for printing on both sides. A motor drives a rotating plate to flip the carton, and the limiting plate prevents the carton from shifting. It is compatible with different carton sizes and uses quick-drying ink and a heating plate to dry the ink. A suction system is also included to handle dust.
It enables simultaneous printing on both sides of the carton, reduces manual flipping steps, improves production efficiency, prevents carton misalignment, ensures printing quality, adapts to different carton sizes, reduces ink contamination, and speeds up drying.

Abstract
Description
A type of carton ink printing machine Technical Field
[0001] This utility model relates to the printing field, and more specifically, to a carton ink printing machine. Background Technology
[0002] The emergence of carton printing machines is closely related to the industrialization process of the packaging industry. With the expansion of global trade and the rise of e-commerce logistics, the market demand for carton packaging has surged. Against this backdrop, automated carton printing machines that integrate functions such as plate making, inking, printing, and slotting have emerged. They have significant advantages: fast printing speed, accurate registration, small color difference, adaptability to different specifications of cartons, and support for personalized customization. They greatly improve production efficiency and reduce labor costs, becoming the core equipment of the modern packaging industry.
[0003] A search revealed that Chinese Patent Publication No. CN219650809U discloses "a carton ink printing machine, including a carton conveyor belt and multiple printing components. Mounting slides extend along the conveying direction of the carton conveyor belt on both sides. Multiple printing components are movably mounted on the mounting slides. One end of each printing component is equipped with a rotating component that is rotatably connected to one side of the mounting slide. This carton ink printing machine allows for cleaning by lifting the end of the printing component with the sliding component, causing the printing component to swing around the mounting slide and be positioned on one side of the carton conveyor belt via the rotating component, thus reversing the entire printing component for easy cleaning. Furthermore, the multiple printing components allow for simultaneous cleaning and printing by using other printing components while one needs cleaning. The distance between adjacent printing components can be adjusted by sliding the sliding component and the rotating component on the mounting slide, ensuring they do not interfere with each other." However, the following drawbacks still exist:
[0004] (1) In actual use, the equipment is limited by the single-sided operation mode and can only complete the printing of one side of the plate. Afterwards, it is necessary to manually collect each piece, flip it over and then put it on the machine again. This operation prolongs the production cycle and is difficult to match the demand for efficient production.
[0005] (2) In actual use, the current equipment has a design shortcoming in the conveying process. The conveyor belt area is not equipped with an effective limiting mechanism, which makes the cartons prone to lateral displacement or longitudinal skew during the movement. This unrestrained displacement can easily lead to printing defects such as misregistration of graphics and text and uneven ink layer thickness. To address this, a carton ink printing machine is proposed. Summary of the Invention
[0006] The purpose of this utility model is to address the current limitations of the equipment in actual use. Due to its single-sided operation mode, the equipment can only complete printing on one side of the plate. Afterward, it is necessary to manually collect each piece, flip it over, and then re-print it on the machine. This operation prolongs the production cycle and is difficult to match the needs of efficient production. At the same time, the current equipment has design shortcomings in the conveyor link. Its conveyor belt area is not equipped with an effective limiting mechanism, which makes the cartons prone to lateral displacement or longitudinal skew during the movement. This unrestrained displacement can easily lead to printing defects such as misregistration of graphics and text and uneven ink layer thickness.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] As shown in Figure 1, this embodiment proposes a carton ink printing machine, including a conveyor belt 1, a double-sided printing component 2 for printing on both sides of a carton, and a limiting component 3 for limiting the printed carton.
[0030] As shown in Figures 2 and 4, the double-sided printing assembly 2 includes a first printing machine 201 fixedly connected to the conveyor belt 1 for printing on cartons. A second printing machine 202 is fixedly mounted on the bottom of the first printing machine 201 for printing. A protective shell 203 is fixedly mounted on one side of the first printing machine 201 and the second printing machine 202. A support base 204 is welded to one side of the protective shell 203. A motor 205 is fixedly mounted inside the support base 204 for providing power. A rotating block 206 is fixedly mounted on the output end of the motor 205. A rotating plate 207 is welded to the periphery of the rotating block 206 for driving the cartons. The carton is flipped over. Inside the protective shell 203, a second conveyor belt 208 is fixedly installed. The middle part of the second conveyor belt 208 is hollowed out to prevent ink contamination. Inside the second printing machine 202, a third conveyor belt 209 is fixedly connected. In use, the carton is transported by the conveyor belt 1 and printed by the first printing machine 201. Quick-drying ink is used to prevent ink transfer and contamination. The motor 205 drives the rotating plate 207 to rotate back and forth, thereby flipping the carton after the first printing. The carton is then carried into the second printing machine 202 for printing by the second conveyor belt 208 and the third conveyor belt 209.
[0031] As shown in Figures 2 and 4, two fixing plates 301 are fixedly installed on the side of the first printing press 201 away from the protective shell 203. A first bidirectional screw 302 is rotatably connected to the two fixing plates 301. A second bidirectional screw 303 is rotatably connected inside the protective shell 203. A third bidirectional screw 304 is rotatably connected to the rotating plate 207 for adjusting the limiting plate 305. Two limiting plates are threaded to the periphery of the first bidirectional screw 302, the second bidirectional screw 303, and the third bidirectional screw 304, respectively. Plate 305 is used for limiting the position. The protective shell 203 is hinged to a door 306 with a latch on the side near the motor 205 to prevent the protective shell 203 from blocking the user from adjusting the second bidirectional screw 303. In use, the limiting plate 305 limits the printed carton to prevent the carton from shifting and deviating. The limiting plate 305 can be adjusted by the first bidirectional screw 302, the second bidirectional screw 303 and the third bidirectional screw 304 to facilitate limiting the position of cartons of different sizes.
[0032] As shown in Figure 4, a heating plate 4 is fixedly installed inside the protective shell 203. Four fixing blocks 5 are welded inside the protective shell 203. Two blower fans 6 are fixedly installed on the top of the fixing blocks 5. In use, in order to adapt to ordinary non-fast-drying inks, the heating plate 4 facilitates ink drying, and the blower fans 6 continuously output hot air to the area where the ink is printed. At the same time, the air drying further accelerates the speed at which the ink dries.
[0033] As shown in Figures 2 and 5, a suction shell 7 is welded to the side of the first printing machine 201 and the second printing machine 202 away from the protective shell 203. A suction fan 8 is fixedly installed at the end of the suction shell 7 near the motor 205. A dust blocking plate 9 is snapped into the inside of the suction shell 7. A dust collection box 10 is fixedly installed at the bottom of the dust blocking plate 9. In use, the dust and other substances generated during the printing process are collected by the suction fan 8 and centrally collected and processed by the dust collection box 10.
[0034] As shown in Figures 4 and 5, a first observation hole 11 is provided on the side of the protective shell 203 away from the conveyor belt 1, and two second observation holes 12 are provided on both sides of the protective shell 203. Tempered glass 13 is fixedly installed inside the first observation hole 11 and the second observation hole 12. When in use, the user can easily see the internal situation of the equipment through the tempered glass 13, and the observation can make it easier to adjust the limit plate 305.
[0035] As shown in Figures 4 and 5, two support plates 14 are fixedly installed on the side of the second printing machine 202 away from the protective shell 203. The two support plates 14 are used in conjunction with the conveyor belt 1. A support block 15 is fixedly installed on the side of the second printing machine 202 away from the support plates 14. During use, the support plates 14 share the pressure of the conveyor belt 1, and the support block 15 supports the rotating plate 207 to prevent the motor 205 from running continuously and reducing its lifespan.
[0036] As shown in Figure 4, a blocking block 16 is welded to the top of the rotating plate 207. The blocking block 16 is used for limiting the position of the carton. When in use, the blocking block 16 can support the carton during rotation to prevent displacement that could lead to printing errors.
[0037] Specifically, in use, this carton ink printing machine works as follows: Cartons are conveyed via conveyor belt 1 and printed on the first printing press 201. Quick-drying ink is used to prevent ink transfer and contamination. Motor 205 drives rotating plate 207 to reciprocate, thus flipping the initially printed cartons. The second conveyor belt 208 and the third conveyor belt 209 carry the cartons into the second printing press 202 for printing (as shown in Figures 2 and 4). A limiting plate 305 limits the printed cartons to prevent displacement deviation. The limiting plate 305 can be adjusted using the first bidirectional screw 302, the second bidirectional screw 303, and the third bidirectional screw 304 to facilitate limiting cartons of different sizes (as shown in Figures 2 and 4). To accommodate ordinary non-quick-drying inks, a heating plate 4 facilitates ink drying. A blower fan 6 continuously outputs hot air to the ink-printing area, further accelerating the ink drying process (as shown in Figure 4).
[0038] All technical features in this embodiment can be freely combined according to actual needs.
[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
