By rotating the screwing member 433, the compression of the first spring 431 can be adjusted, thereby changing the pressure of the pressure plate 429 on the discharge roller 423, and thus adjusting the rotational speed of the discharge roller 423.

[0045] See Figure 8 The roll-to-roll printing assembly 42 also includes a clamping adjustment member 434, a fixing post 435, and a second spring member 436 located within the housing 428. One end of the clamping adjustment member 434 is fitted with a first pressure roller 424, and a slotted hole is provided on the roll-to-roll moving member 422 corresponding to the first pressure roller 424 for insertion, allowing the first pressure roller 424 to move within the slotted hole under the action of the clamping adjustment member 434. The fixing post 435 is mounted on the roll-to-roll moving member 422. One end of the second spring member 436 is hung on the clamping adjustment member 434, and the other end is used to movably hang the fixing post 435. By adjusting the position of the second spring member 436 on the fixing post 435, the distance between the first pressure roller 424 and the second pressure roller 425 at the same end can be adjusted to accommodate roll-to-roll printing of different thicknesses.

[0046] See Figure 9 and Figure 10 The cylindrical printing assembly 44 includes an abutment frame 441, a movable bracket 442, a fourth drive member 443, a support member 444, and an abutment member 445. The abutment frame 441 abuts against the lower end of the chassis 10, providing support for the entire cylindrical printing assembly 44. The movable bracket 442 is located inside the abutment frame 441. The fourth drive member 443 is fixed inside the abutment frame 441 to an electrical connection connector 32. It is located at one end of the movable bracket 442 and is used to tilt one end of the movable bracket 442 at a preset angle to accommodate cylindrical products of different diameters.

[0047] The system comprises two support members 444, each positioned at one end of the movable bracket 442, and two abutment members 445, fixed to the two support members 444 for contacting the cylindrical product. The abutment frame 441 can be a metal frame, providing good strength; the movable bracket 442 is an adjustable structure for easy angle adjustment; the fourth drive member 443 can be a servo motor for precise angle control; the support members 444 can be metal rods; and the abutment members 445 can be rubber blocks to increase the contact area and friction with the cylinder.

[0048] Furthermore, the cylindrical printing assembly 44 also includes two fifth driving components 446, each located within one of the two support members 444 and electrically connected to the connector 32. The driving end of the fifth driving component 446 drives the abutment member 445 to rotate via the third conveyor belt 447, thereby rotating the cylindrical product for printing. The addition of the fifth driving component 446 enables the cylindrical product to rotate automatically during the printing process, achieving omnidirectional printing.

[0049] Additionally, see Figure 3 and Figure 12 The multi-functional UV printing equipment also includes a lifting assembly 50, located at the lower end of the chassis 10, and comprising a first drive component 51 and a lifting component 52. The first drive component 51 is fixed to the chassis 10, and the lifting component 52 passes through a fixed slot 31, wherein the first drive component 51 connects to and drives the lifting component 52 to move the fixed slot 31 up and down. The function of the lifting assembly 50 is to adjust the printing height of the platform printing assembly 41 or the roll-to-roll printing assembly 42 relative to the printhead assembly 22.

[0050] When using the platform printing assembly 41 or the roll-to-roll printing assembly 42, depending on the thickness of the printing material or printing requirements, the first driving component 51 can drive the lifting component 52 to raise or lower the fixed slot 31, thereby adjusting the distance between the printing assembly and the printhead assembly 22 to ensure print quality. The first driving component 51, as shown in the diagram... Figure 12 The diagram shows the drive structure of the motor and conveyor belt. Of course, this is not limited to this; for example, it could also be an electric push rod, which has the characteristics of simple structure and reliable operation. The lifting component 52 can be a screw and nut mechanism, which can achieve precise lifting control.

[0051] In addition, see Figure 2 and Figure 13The ink jetting mechanism 20 also includes an ink stack assembly 24 and a drive assembly 25. The ink stack assembly 24 is located inside the housing 10 and close to the printhead assembly 22, and is electrically connected to the control box assembly 21. Its function is to maintain and service the printhead assembly 22, such as cleaning the printhead and replenishing ink. The drive assembly 25 is located inside the housing 10 and is used to connect to and drive the printhead assembly 22 to reciprocate horizontally, allowing the printhead assembly 22 to print over a larger area and expanding the printing area.

[0052] The printhead assembly 22 can be configured with two units, each containing ink cartridges of different materials or colors. The addition of the ink stack assembly 24 improves the lifespan and print quality of the printhead assembly 22, and reduces printhead clogging and other problems. Alternatively, the ink stack assembly 24 can also correspond to the printhead assembly 22, also configured as two units, located on either side of the drive assembly 25. The drive assembly 25 allows the printhead assembly 22 to move flexibly in the horizontal direction, increasing printing flexibility and coverage.

[0053] The implementation principle of this embodiment is as follows: The multi-functional UV printing device provides overall support and installation structure through the chassis 10, the ink jetting mechanism 20 achieves precise ink jetting, the adapter component 30 provides a guarantee for the installation and fixation of different printing components, and the three different printing components in the printing mechanism 40 can be installed in rotation according to different printing needs. This design overcomes the shortcomings of traditional printing devices that can only work for specific types of printing tasks, realizing the function of one device to meet multiple printing needs. Users no longer need to purchase multiple different types of printing devices, reducing equipment purchase and maintenance costs, and also saving space. The quick replacement and installation of different printing components improves work efficiency, making the device more versatile and flexible, and suitable for more application scenarios.

[0054] The addition of the lifting assembly 50 further enhances the adaptability and print quality of the equipment. By adjusting the height between the printing assembly and the printhead assembly 22, it can better accommodate printing materials of different thicknesses, avoiding problems such as blurry prints or ink splatter caused by improper distance. Simultaneously, this adjustable design allows the equipment to more flexibly adjust printing parameters when facing different types of printing tasks, improving its versatility and practicality, and further reducing user operating costs and maintenance difficulties.

[0055] By adjusting the rotation speed of the feeding roller 423 in the roll-to-roll printing assembly 42, the feeding speed of the printing roll can be better controlled, avoiding problems such as excessive slack or tension of the roll and ensuring the stability of print quality. Simultaneously, adjusting the distance between the first pressure roller 424 and the second pressure roller 425 can accommodate printing rolls of different thicknesses, enabling the equipment to handle more types of roll-to-roll printing tasks, further improving the equipment's versatility and practicality, and meeting the diverse printing needs of users.

[0056] By incorporating a fifth drive element 446 within the cylindrical printing assembly 44, the efficiency and quality of cylindrical printing can be significantly improved. By rotating the cylindrical product, the printhead assembly 22 can continuously print on the cylindrical surface, avoiding the hassle of repeatedly adjusting the cylinder's position required in traditional printing methods, reducing printing time, and increasing work efficiency. Simultaneously, rotational printing ensures uniformity and consistency in the printing, resulting in more aesthetically pleasing and precise prints, further enhancing the equipment's performance and competitiveness in cylindrical printing.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
