[0003] To address the above problems, the following technical solutions are proposed:
[0004] A corrugated cardboard box printing device includes a conveyor belt, a printing device mounted above the conveyor belt, a printing mold, and several printing slots arranged in parallel. Adjacent printing slots are separated by baffles. A film cloth is fixedly connected to the bottom surface of the printing slots. The film cloth has die holes. A first scraper and a second scraper are respectively mounted at both ends of the top of the die holes in the direction of the printing slots. The bottoms of the first scraper and the second scraper abut against the film cloth. The first scraper and the second scraper are fixedly connected by a connecting rod. Two printing slots located at both ends are respectively fixedly connected to mounting platforms. An electric cylinder is mounted on one of the mounting platforms. A connecting rod is fixedly connected to one end of the telescopic rod of the electric cylinder. The top of the first scraper is fixedly connected to the connecting rod. A hydraulic cylinder is fixedly connected to the top of the printing device. A mounting plate is mounted above the printing device. A support foot is fixedly connected to the bottom of the mounting plate. One end of the telescopic rod of the hydraulic cylinder is fixedly connected to the top of the mounting platform. The hydraulic cylinder is mounted to the top of the mounting plate by bolts. One end of the telescopic rod of the hydraulic cylinder passes through the mounting plate.
[0005] Furthermore, a first support plate is also provided on the mounting plate on which the electric cylinder is installed, and a second support plate is provided on another mounting plate. One end of the telescopic rod of the electric cylinder passes through the first support plate, and the end of the connecting rod away from the electric cylinder passes through the second support plate.
[0006] Furthermore, the support plate and the printing groove are fixedly connected by reinforcing ribs.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] A corrugated cardboard box printing device includes a conveyor belt 1, a printing device mounted above the conveyor belt 1, a printing mold, and several printing slots 4 arranged in parallel. Adjacent printing slots 4 are separated by baffles 5. A film cloth 7 is fixedly connected to the bottom surface of the printing slot 4. The film cloth 7 is provided with die holes 71. A first scraper 61 and a second scraper 62 are respectively arranged at both ends of the top of the die holes 71 in the direction of the printing slots 4. The bottoms of the first scraper 61 and the second scraper 62 abut against the film cloth 7. The first scraper 61 and the second scraper 62 are fixedly connected by a connecting rod 63. Two printing slots 4 located at both ends are respectively fixedly connected to the outer side of a mounting platform 41. An electric cylinder 32 is mounted on one of the mounting platforms 41. One end of the extension rod of the electric cylinder 32 is fixedly connected to the electric cylinder 32. A connecting rod 321 is fixedly connected to the top of the first scraper 61. A hydraulic cylinder 31 is fixedly connected to the top of the printing device. A first support plate 421 is also provided on the mounting plate 22 on which the electric cylinder 32 is provided. A second support plate 422 is provided on another mounting plate 22. One end of the telescopic rod of the electric cylinder 32 passes through the first support plate 421, and the end of the connecting rod 321 away from the electric cylinder 32 passes through the second support plate 422. A reinforcing rib is fixedly connected between the support plate and the printing groove 4. A mounting plate 22 is provided above the printing device. A support foot 21 is fixedly connected to the bottom of the mounting plate 22. One end of the telescopic rod of the hydraulic cylinder 31 is fixedly connected to the top of the mounting platform 41. The hydraulic cylinder 31 is installed on the top of the mounting plate 22 by bolts. One end of the telescopic rod of the hydraulic cylinder 31 passes through the mounting plate 22.
[0021] Conveyor belt 1 transports the carton at a uniform speed to the designated position below the printing device. At this time, the hydraulic cylinder 31, installed on the top of the mounting plate 22, is activated, and its telescopic rod extends downward. Since one end of the telescopic rod is fixedly connected to the top of the printing device, the printing device moves downward, causing the film cloth 7 at the bottom of the printing tank 4 to approach the surface of the corrugated carton.
[0022] In the printing tank 4, the electric cylinder 32, located on the mounting plate 22 at one end, begins to operate. The telescopic rod of the electric cylinder 32 performs a linear telescopic motion, driving the connecting rod 321, which is fixedly connected to it, to move. The connecting rod 321 is connected to the top of the first scraper 61, thereby causing the first scraper 61 to move horizontally along the surface of the film cloth 7. The first scraper 61 is fixedly connected to the second scraper 62 via the connecting rod 63, so the second scraper 62 also moves synchronously.
[0023] Since the bottoms of the first scraper 61 and the second scraper 62 abut against the film cloth 7, they scrape the pigment in the printing tank 4 evenly toward the die hole 71 during their movement. The pigment penetrates through the die hole 71 to the surface of the corrugated cardboard box below, completing the printing process.
[0024] In the entire device, the first support plate 421, located on the mounting plate 22 where the electric cylinder 32 is located, provides stable support and guidance for the telescopic rod of the electric cylinder 32, ensuring smooth and precise telescopic movement. Meanwhile, the second support plate 422 on the other end of the mounting plate 22 guides the movement of the connecting rod 321, ensuring the linear movement trajectory of the first scraper 61 and the second scraper 62, thereby achieving uniform pigment distribution and precise printing.
[0025] The reinforcing ribs that are fixedly connected between the support plate and the printing trough 4 further enhance the structural strength and stability of the printing device, effectively resisting various forces and vibrations generated during operation, and ensuring the accuracy and consistency of printing.
[0026] For example, in practical use, if more complex patterns or combinations of different colors need to be printed, the shape and distribution of the die holes 71 can be adjusted as needed, and the ink in the printing tank 4 can be replaced. At the same time, the movement speed, stroke, and force of the hydraulic cylinder 31 and the electric cylinder 32 can be precisely adjusted through the control system to adapt to corrugated boxes of different materials and thicknesses, achieving the best printing effect.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
