Description

Technical Field

[0001] The invention belongs to the technical field of printing machines, and in particular relates to a printing device for producing packaging paper boxes. Background Art

[0002] Paper boxes are widely used as important packaging materials for products. They are not only environmentally friendly, but also have the advantages of low cost, light weight, and easy transportation. Paper boxes are now widely used in electronics, food, beverages, alcohol, tea, cigarettes, medicine, health products, cosmetics and other industries. They are indispensable in product packaging. Packaging cartons need to be printed with patterns before they are made into boxes.

[0003] Most common cardboard printing machines use a single printing roller and a fixed workbench, which makes the placement and removal of paper boxes relatively cumbersome during the printing process. In addition, for paper boxes of different sizes, the printing roller needs to be replaced or the workbench needs to be adjusted frequently, which greatly reduces the printing efficiency and flexibility. In addition, when printing deviation and poor printing occur during the printing process of existing paper box printing machines, it is impossible to observe and deal with them in time, thus affecting the printing quality.

[0045] The working principle of this embodiment is as follows. When the entire printing equipment is started, first, the paint in the paint box 1404 is driven by the pump 1406 and flows into the two paint brush wheels 1403 through the conveying pipe 1407, ensuring that the paint brush wheels 1403 are evenly covered with paint. At the same time, the first motor 311 is started, driving the second reel 313 to rotate, and through the friction transmission of the transmission belt 314, the first reel 309 rotates synchronously, thereby driving the paperboard 306 to slide along the second slide rail 304 to achieve continuous conveying of paper.

[0046] As the paper is transported, the printing roller 15 starts to work, and the fourth motor 1512 drives the fourth gear 1511 to rotate, thereby driving the bidirectional rack 1001 and the second gear 1501 on the printing roller 15 to rotate synchronously, thereby realizing the rotational movement of the printing roller 15. The printing roller 15 fits tightly with the paint brush wheel 1403, ensuring that the paper can be evenly coated with paint when passing through.

[0047] During the printing process, in order to ensure the smooth transmission of paper, the paper feeder 11 plays a key role. The first hydraulic push rod 1101 drives the T-shaped slide column 1102 to slide along the middle of the paper feeder 11, thereby driving the I-type plate 1103 and the boat-shaped pressure plate 1105 to move up and down. The elastic force of the spring 1104 ensures that the boat-shaped pressure plate 1105 always maintains a certain pressure on the paper, ensuring that the paper will not deviate during the transmission process.

[0048] In addition, in order to further improve the accuracy and efficiency of printing, the third motor 1508 drives the rotating plate 1509 to rotate, thereby driving the shift block 1510 to slide in the slide groove 1506. The movement of the shift block 1510 is transmitted to the third gear 1502 through the curved rack 1503, so that the meshing relationship between it and the second gear 1501 changes, thereby achieving fine-tuning of the rotation speed and direction of the printing roller 15. This fine-tuning function enables the equipment to cope with paper of different materials and thicknesses, ensuring stable and consistent printing effects.

[0049] During the entire printing process, the operator can observe the printing situation in the brush box 14 in real time through the observation window 1401, and move the position and angle of the brush box 14 through the second handle 1405. By controlling the extension and contraction of the third hydraulic push rod 1308, the angle of the L-shaped pull plate 1307 and the round rod 1309 can be adjusted, so as to adjust the printing parameters in time and ensure the stability and consistency of the printing quality. Through the coordinated work of multiple components, this printing equipment realizes the functions of automatic paper conveying, uniform coating, timely detection and processing of printing deviation and poor printing, etc., which greatly improves the printing efficiency and quality.
