Description

Technical Field

[0001] The invention relates to the technical field of corrugated board processing, and in particular to an automatic printing device and process for corrugated board processing. Background Art

[0002] Corrugated cardboard is used in various fields due to its light weight, impact resistance and environmentally friendly raw materials. The main field is the packaging industry, where it is used to protect and contain internal products, and to cushion impact during transportation to prevent internal goods and products from being damaged. At the same time, in some cases, it is also necessary to print patterns on the surface of the corrugated paper. Usually, these patterns are printed uniformly as a necessary representation of product packaging and can play a role in beautifying and promoting products.

[0003] When printing, professional printing equipment is required to print the patterns. For example, the Chinese invention patent document with application number CN202110568734.X discloses an environmentally friendly green printing process for corrugated cardboard and its equipment, including a base, an isolation plate is symmetrically fixed on one side of the top of the base, and an installation groove is opened on the top of the end of the base away from the isolation plate.

[0004] The above invention drives the rotating rod to rotate by the rotation of the first motor, drives the connecting rod to rotate by the limiting of the first limit hole and the first limit rod, and then enables the push block to push the corrugated cardboard at the bottom into the fixed frame, thereby realizing the sequential feeding of the corrugated cardboard. At the same time, the rotation of the second motor will drive the rotation of the first rotating rod and the second rotating rod. On the one hand, the rotation of the second rotating rod will drive the limiting block to move back and forth along the circular groove, and will drive the wiping sponge on the sliding rod to scrub the corrugated cardboard. On the other hand, the rotation of the first rotating rod will cause different suction holes to absorb dust to prevent the first rotating rod from being blocked, and the dust in the fixed frame will be absorbed by the dust suction device to clean the corrugated cardboard, thereby improving the quality of the printed product.

[0005] However, although the surface of the corrugated cardboard is cleaned by the first rotating roller and the wiping sponge in the above document, the cleaning effect of only relying on negative pressure to absorb impurities and dust is poor, and a strong negative pressure source is required as a supply, and the stability of the printed corrugated cardboard itself needs to be considered.

[0006] For example, the Chinese invention patent document with application number CN202111555988.4 discloses a corrugated cardboard printing device, including a support seat, a pair of connecting plates fixedly connected to the bottom of the support seat, a cleaning brush fixedly connected to the surface of the connecting plate, a pair of support legs fixedly connected to the bottom of the connecting plate, a conveyor belt rotatably provided on the support seat, the surface of the conveyor belt abuts against the surface of the cleaning brush, a pair of support frames fixedly connected to the side walls of the support seat, a protective cover fixedly connected between the support frames, and a printing mechanism rotatably provided inside the protective cover; compared with the prior art.

[0007] In the above invention, when the corrugated cardboard and the surface of the printing roller are squeezed against each other, the printing roller moves in a circular motion, which can cause the connecting spring to shift in position under the action of the driving ball, and can pull the position of the movable shaft, that is, it can ensure that the elastic shaft stirs the internal ink during the movement, and can also cause the elastic ball to knock on the inner wall of the ink outlet plate, which can cause the internal ink to move, avoid uneven coloring of the ink, and ensure the quality of printing.

[0008] However, the above invention points out that uneven printing, i.e. blank space, may occur during printing, and the above invention reduces the difficulty of printing by improving the ink discharge and cleaning the ink plate to ensure the flatness of the ink plate. However, this method still has defects because the structural defects of the corrugated cardboard itself have not been solved, so there is still a situation where the corrugated cardboard is partially sunken. Summary of the invention

[0009] In order to overcome the technical defects of the prior art, the present invention provides an automated printing device and process for corrugated cardboard processing, which can clean the surface of the corrugated cardboard and print it flat.

During cleaning, the positive pressure tube on one side is used to blow airflow to the corrugated cardboard, and then the impurities will move with the airflow to ensure the cleanliness of the surface of the corrugated cardboard, and the absorption tube can absorb these impurity-containing gases. Since it is necessary to leave a space for the corrugated cardboard to pass through at the bottom of the absorption shell, in order to better guide the flow of the airflow, a guide block is arranged on one side of the absorption shell, and the bottom of the guide block can better guide the flow of the airflow. Compared with the traditional method, which only uses negative pressure for single absorption, the device can better avoid impurity residues;

[0024] When the corrugated cardboard body moves to the bottom of the printing body, in the traditional way, the printing body starts to press down on the corrugated cardboard for printing. At this time, the upper surface of the corrugated cardboard sinks, which will produce blank space and affect the printing quality. The telescopic cylinder can drive the flattening component on the carrier to move, and when in use, high-pressure gas is filled in the sealing plate, and then the rotating ring belt is close to the two sides of the corrugated cardboard. The lifting column close to the corrugated cardboard is attracted and raised by the wing plate, and then the gas can lift the gap part of the corrugated cardboard through the through hole, and the lifting column on the side away from the corrugated cardboard body can be pushed into the rotating ring belt to avoid gas leakage. The upper surface of the corrugated cardboard body is lifted up to ensure that it does not sink during printing, thereby ensuring the printing quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A process for processing corrugated paperboard, S1: preparing the corrugated paperboard to be printed, and ensuring that the direction of the cavity below the printing surface of the corrugated paperboard is perpendicular to the traveling direction of the conveyor belt 202;

[0045] S2: Apply tough glue to the upper surfaces of both sides of the corrugated cardboard, using PVP glue, and then dry it;

[0046] S3: placing the corrugated cardboard on the conveyor belt so that the two side edges of the corrugated cardboard are just located on the soft belt 203, and then passing through the cleaning component 8 to be cleaned, the attached impurities are blown off, and absorbed and transferred to ensure the cleanliness of the upper surface of the corrugated cardboard;
