Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0035] like Figure 1-7 As shown, an environmentally friendly printing device for color printing of wear-resistant corrugated cardboard boxes, according to an embodiment of the present invention, includes a conveyor base 3 and a printing component 9. The bottom of the conveyor base 3 is fixed with a support leg 2, which provides stable support for the conveyor base 3. The printing component 9 is located above the conveyor base 3. The printing component 9 uses existing conventional technology and is only required to print on the cardboard 10; no further limitations or elaborations are provided. It also includes:
[0036] The printing component 9 is connected to the conveyor seat 3 via the lifting assembly. The lifting assembly is used to support the printing component 9 and drive it to rise and fall.
[0037] The conveyor roller 5 and the conveyor roller 6 are provided. The top of the conveyor seat 3 is provided with a conveying groove 4. Multiple conveyor rollers 6 are evenly arranged on the conveyor seat 3 below the printing component 9. Air holes 8 are provided on the conveyor rollers 6. Multiple conveyor rollers 5 are evenly arranged on the conveyor seat 3 on both sides of the conveyor rollers 6. Both the conveyor rollers 5 and the conveyor rollers 6 protrude from the surface of the conveying groove 4.
[0038] A drive assembly is mounted on the conveyor base 3. The drive assembly is used to drive all the conveyor rollers 5 and 6 to rotate synchronously and in the same direction.
[0039] A negative pressure assembly is installed on the conveyor seat 3. The negative pressure assembly is connected to all the conveyor rollers 6 and draws air through the air holes 8.
[0040] The feeding end of the conveyor seat 3 is also equipped with a material guiding component. The material guiding component is located on the upper side of the conveyor roller 5 and is used to assist in centering the paperboard 10.
[0041] In this embodiment of the invention, the lifting component is specifically designed to support the printing component 9 and precisely control its lifting action to ensure efficient printing on paperboard 10 of different thicknesses.
[0042] The combination of conveyor roller 5 and conveyor roller 6, under the precise control of the drive assembly, enables all rollers to rotate synchronously and in the same direction, thereby ensuring smooth printing and conveying of the paperboard 10.
[0043] It is worth mentioning that the position of the second conveyor roller 6 corresponds to that of the printing assembly 9, ensuring the accuracy of the printing process. The negative pressure assembly is connected to all the second conveyor rollers 6, and effectively draws air through the air holes 8, allowing the cardboard 10, which passes through the center of the guide assembly, to be stably conveyed and closely adhered to the second conveyor roller 6 for smooth transport. This design not only improves the stability of the cardboard 10 during the conveying process, but also significantly improves the printing quality of the cardboard 10 by the printing assembly 9.
[0044] like Figure 1 , 3 As shown in Figure 7, in a preferred embodiment of the present invention, the lifting assembly includes a fixed block 11 and a vertical telescopic cylinder 12. A fixed block 11 is fixed at each of the front and rear ends of the printing assembly 9. A vertical telescopic cylinder 12 is fixed at the lower side of the fixed block 11. The lower end of the vertical telescopic cylinder 12 is fixed to the top of the conveyor seat 3. The two vertical telescopic cylinders 12 and the fixed block 11 cooperate to support the printing assembly 9 and drive it to lift.
[0045] The first conveyor roller 5 and the second conveyor roller 6 have the same diameter. The conveyor base 3 has several roller grooves 23 for accommodating the first conveyor roller 5 and the second conveyor roller 6. Both the first conveyor roller 5 and the second conveyor roller 6 are rotatably connected to the roller grooves 23. Both ends of the first conveyor roller 5 and the second conveyor roller 6 are also rotatably connected to the conveyor base 3. This ensures that any leaking air holes 8 are sucked in, resulting in high reliability. It should be noted that the height of the first conveyor roller 5 and the second conveyor roller 6 protruding from the surface of the conveyor groove 4 is not limited, as long as it allows for stable conveying of the cardboard 10.
[0046] The drive assembly includes a conveyor motor 1, pulleys 20, and a transmission belt 21. A transmission cavity 19 is provided on one side of the conveyor seat 3. One end of conveyor roller 5 and conveyor roller 6 extends into the transmission cavity 19. The conveyor motor 1, which is connected to one of the conveyor rollers 5 or 6, is fixed on the conveyor seat 3. Pulleys 20 are fixed on both conveyor roller 5 and conveyor roller 6 in the transmission cavity 19. Two adjacent pulleys 20 are connected by the transmission belt 21. When the conveyor motor 1 drives the conveyor roller 5 to rotate, the transmission of the pulleys 20 and the transmission belt 21 enables all conveyor rollers 5 and 6 to rotate synchronously and in the same direction, ensuring the reliability of conveying the cardboard 10.
[0047] The negative pressure assembly includes a suction fan 7. A connecting cavity 22 is provided on the other side of the conveyor seat 3. The other end of the second conveyor roller 6 extends into the connecting cavity 22, and the end of the second conveyor roller 6 located within the connecting cavity 22 is open. The connecting cavity 22 communicates with the air hole 8 through the inner cavity of the second conveyor roller 6. The suction fan 7 is fixed to the conveyor seat 3 and communicates with the connecting cavity 22. Thus, when the suction fan 7 operates, it generates negative pressure in the air hole 8, causing the cardboard 10 to adhere to the second conveyor roller 6, improving the stability of the conveying process and the reliability of the printing. Furthermore, the shape of the air hole 8 is not limited; it can be evenly distributed on the second conveyor roller 6. The rotational connection between the second conveyor roller 6 and the roller groove 23 ensures the reliability of the suction fan 7 in drawing air from the air hole 8.
[0048] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the material guiding assembly includes an inverted U-shaped frame 13, a second vertical telescopic cylinder 14, a pressing wheel 15, a wheel frame 16, a horizontal telescopic cylinder 17, and a conical guide column 18. Several horizontal telescopic cylinders 17 are fixed on both sides of the feeding end of the conveying seat 3, and the horizontal telescopic cylinders 17 on both sides of the conveying seat 3 are arranged in a one-to-one correspondence. The output end of the horizontal telescopic cylinder 17 is rotatably mounted with a conical guide column 18. The conical guide column 18 is horizontally arranged, and the conical guide column 18 has a conical structure with a larger end near the horizontal telescopic cylinder 17 and a smaller end away from the horizontal telescopic cylinder 17. An inverted U-shaped frame 13 is also installed across the feeding end of the conveying seat 3. A second vertical telescopic cylinder 14 is fixed in the middle of the inverted U-shaped frame 13. A wheel frame 16 is fixed at the lower end of the second vertical telescopic cylinder 14, and a pressing wheel 15 is rotatably mounted on the wheel frame 16.
[0049] Preferably, the inverted U-shaped frame 13 can be adjusted in position along the length of the conveyor seat 3. The specific adjustment structure is not limited, which is beneficial to changing the position of the pressing roller 15 and improving the pressing and guiding effect.
[0050] Preferably, the horizontal telescopic cylinders 17 on both sides of the conveyor seat 3 are synchronously telescopic, which facilitates the stable and reliable conveying of the paperboard 10 using the structure of the conical guide column 18, and keeps the paperboard 10 centered.
[0051] Preferably, the distance between the corresponding conical guide columns 18 on both sides of the conveyor seat 3 gradually decreases from the feed position toward the printing assembly 9. The purpose of this arrangement is to use the structure of the conical guide columns 18 to gradually center the cardboard 10, improve the overall conveying reliability, avoid jamming, and thus reliably guide the cardboard 10 to the area where the conveyor roller 6 is located.
[0052] Furthermore, the control of each component can be achieved using a PLC controller disclosed in the existing technology. There are no specific limitations on the model and circuit connection of each component, and they can be flexibly configured in practical applications.
[0053] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
