[0023] Embodiment 1

[0024] As shown in the attached Figures 1 to 4 A high-efficiency printing and feeding mechanism for cartons is shown, including a bottom plate 1. The bottom plate 1 is made of metal material and plays a supporting role, providing a relatively flat working platform for the device. Support plates 2 are arranged on both sides of the top of the bottom plate 1. These support plates 2 provide a stable foundation for the entire feeding mechanism. Its technical effect is to ensure the stability of the equipment during high-speed operation, reducing problems such as errors or inaccurate printing caused by vibration or deviation. Maintenance holes 3 are arranged on the outer walls of the support plates 2. These maintenance holes 3 facilitate the observation and maintenance of internal components.

[0025] Two groups of support plates 2 are provided with transverse support plates 4 through the inspection holes 3. There are several groups of transverse support plates 4, and each group of transverse support plates 4 is evenly arranged along the horizontal direction of the support plate 2. The design of the transverse support plate 4 makes the conveying mechanism 5 more stable, reduces the shaking and deviation during the conveying process, and improves the feeding accuracy and reliability. A conveying mechanism 5 is arranged on one side of the transverse support plate 4. This design enables the cardboard box to move smoothly and continuously in the feeding channel, improving the feeding speed and accuracy. A sliding rod mechanism 6 is arranged on the top of the support plate 2. The design of this sliding rod mechanism 6 enables the printing roller 7 to be adjusted as needed, so that it can operate stably at different height positions. A printing roller 7 is arranged at the center of the two groups of sliding rod mechanisms 6. The printing roller 7 can be adjusted and positioned flexibly to adapt to the printing requirements of cardboard boxes of different sizes and shapes. Pressing mechanisms 8 are arranged on both sides of the printing roller 7. The design of the pressing mechanism 8 ensures that the cardboard box can be stably held on the conveying mechanism during the printing process, preventing it from moving or shifting, thus ensuring the accuracy and consistency of printing. A positioning device 9 is arranged on one side of the printing roller 7. The design of this positioning device 9 enables the cardboard box to be accurately positioned during the printing process, ensuring the accuracy and consistency of printing. By adjusting the position of the positioning baffle, it can adapt to the printing requirements of cardboard boxes of different sizes and shapes.

[0026] Embodiment 2

[0027] Based on Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, see the following description for details:

[0028] As a preferred embodiment, the conveying mechanism 5 includes a drive shaft 10 and a conveyor belt 11. The conveyor belt 11 is arranged on the outer wall of the drive shaft 10. Further, since the conveyor belt 11 can perform circular motion around the transverse support plate 4, this makes the conveying process more stable, reduces the shaking and deviation of the cardboard box during the conveying process. In addition, by optimizing the design of the conveying mechanism 5, the phenomenon of material jamming is effectively reduced, ensuring the continuity and stability of the feeding process.

[0029] As a preferred embodiment, the transverse support plate 4 is fixed to the inspection hole 3 by bolts, so that the conveyor belt 11 performs circular motion around the transverse support plate 4. Further, by fixing the transverse support plate 4 to the inspection hole 3 with bolts, it can ensure that the conveyor belt 11 maintains the correct position and tension during operation, thus reducing the swing or deviation of the conveyor belt 11. Adjusting the position of the transverse support plate 4 through the inspection hole 3 can also adjust the tension of the conveyor belt 11, so that the device can adapt to different cardboard boxes.

[0030] As a preferred embodiment, the slide bar mechanism 6 includes a vertical plate 12, a slide rail 13, a slider 14 and a manual knob 15. A slide rail 13 is arranged inside the vertical plate 12, a slider 14 is arranged on the outer wall of the slide rail 13, and a manual knob 15 is arranged on the top of the slide rail 13. By rotating the manual knob 15, the slide rail 13 can perform circular motion, so that the slider 14 moves up and down along the outer wall of the slide rail 13. Further, the design of this slide bar mechanism 6 enables the printing roller 7 to be adjusted as needed, so that it can operate stably at different height positions. By adjusting the position of the slider 14 through the manual knob 15, the contact pressure between the printing roller 7 and the carton can be accurately controlled, thus ensuring the printing quality.

[0031] As a preferred embodiment, a support rod 22 is arranged at the inner center of the printing roller 7. The printing roller 7 is composed of multiple groups of elliptical printing cylinders, and it rotates independently with the support rod 22 as the center. Further, this design enables the printing roller 7 to transfer the ink to the surface of the carton more evenly, improving the printing quality. The combined form of multiple groups of elliptical printing cylinders can provide more stable and uniform pressure during the printing process, ensuring the consistency and clarity of the ink on the surface of the carton.

[0032] As a preferred embodiment, the pressing mechanism 8 includes a connecting frame 16 and a pressing roller 17. A pressing roller 17 is arranged at the bottom of the connecting frame 16. The pressing roller 17 makes the carton closely fit with the conveying mechanism 5. Further, the pressing roller 17 is made of rubber material. The design of the pressing roller 17 enables the carton to be firmly fixed on the conveying mechanism 5, thus ensuring the accuracy and consistency of printing. By adjusting the position and pressure of the pressing roller 17, cartons of different thicknesses and materials can be adapted, improving the applicability and flexibility of the equipment.

[0033] As a preferred embodiment, the positioning device 9 includes columns 18, adjusting rods 19, positioning baffles 20 and rotary pins 21. There are four groups of columns 18, and every two groups of columns 18 are evenly arranged along the horizontal direction of the support plate 2. An adjusting rod 19 is arranged on the outer wall of the column 18, a positioning baffle 20 is arranged on one side of the adjusting rod 19, and a rotary pin 21 is arranged above the adjusting rod 19. By rotating the rotary pin 21, the adjusting rod 19 can be telescoped along the horizontal direction of the column 18, so that the position of the positioning baffle 20 on the conveying mechanism 5 can be adjusted. Further, the design of this positioning device 9 enables the carton to be accurately positioned during the printing process, ensuring the accuracy and consistency of printing. By adjusting the position of the positioning baffle 20, the printing requirements of cartons of different sizes and shapes can be adapted. The design of the rotary pin 21 enables the staff to quickly and conveniently adjust the positioning baffle 20, improving the work efficiency.

[0034] The working process of this utility model is as follows: First, the cardboard box to be printed is fed into the conveying mechanism 5, and the conveyor belt 11 starts to move, driving the cardboard box to move forward. During the conveying process, the adjusting rod 19 and the positioning baffle 20 of the positioning device 9 will be adjusted according to the size and shape of the cardboard box. The adjusting rod 19 is telescoped by rotating the plug pin 21, so as to accurately position the cardboard box and ensure the accuracy of printing. As the cardboard box moves, the pressing roller 17 at the bottom of the connecting frame 16 of the pressing mechanism 8 closely fits the cardboard box with the conveying mechanism 5. When the cardboard box is accurately positioned and fixed, the sliding rod mechanism 6 starts to work. The support rod 15 inside the printing roller 7 ensures that each group of elliptical printing cylinders can rotate independently, realizing uniform ink transfer and printing effect. The above is the working principle of this high-efficiency printing and feeding mechanism for cardboard boxes.
