The ink tray is mounted on a mounting frame. The ink delivery roller is connected to a driven gear. The driven gear is driven by a driving gear. The driving gear is driven by an ink delivery power source. The mounting frame is height-adjustable. The ink delivery roller is connected to a bearing. The bearing is equipped with a lifting seat. The lifting seat is connected to the output shaft of a lifting cylinder. The lifting cylinder is connected to the mounting frame. The mounting frame is connected to a gear seat. The driving gear and the ink delivery power source are both mounted on the gear seat.

[0005] In this design, the lifting base drives the ink delivery roller to rise and fall via bearings, moving it closer to or further away from the ink tray for easy cleaning. The mounting frame drives the ink tray and ink delivery roller to rise and fall as a whole, allowing adjustment of the distance between the ink delivery roller and the printing roller.

[0006] Preferably, a rack is provided below the mounting bracket, the rack meshes with an adjusting gear, and the adjusting gear is connected to an adjusting power source.

[0007] In this scheme, the power source is adjusted by adjusting the gears that drive the rack and pinion and the mounting bracket to lift and lower.

[0008] Preferably, the gear seat is mounted on the lifting cylinder body.

[0009] This design features a compact structure.

[0010] Preferably, a transition gear is connected between the driving gear and the driven gear, and the transition gear is mounted on the gear seat.

[0011] In this design, there is a gap between the ink delivery roller and the ink delivery power source, and the ink delivery power source will not interfere with the ink tray or the mounting bracket.

[0012] Preferably, the lifting seat is provided with a through groove for accommodating the bearing, the groove opening is provided with a pin, and the two side walls of the through groove are provided with pin holes for the pin to pass through.

[0013] In this design, the bearing is fixed by a pin fitting into the groove bottom.

[0014] Preferably, the lifting base is connected to a protective cover by fasteners, and the protective cover has a U-shaped opening for the ink delivery roller to pass through.

[0015] This design prevents ink from splashing into the channel.

[0016] The beneficial effects of this utility model are as follows: the lifting seat drives the ink delivery roller to rise and fall via bearings, moving it closer to or further away from the ink tray for easy cleaning; the mounting frame drives the ink tray and ink delivery roller to rise and fall as a whole, allowing adjustment of the distance between the ink delivery roller and the printing roller; the lifting cylinder, drive gear, and ink delivery power source are all connected to the mounting frame, resulting in a simple and compact structure with low noise. Therefore, this utility model has substantial features and progress compared to the prior art. Attached Figure Description

[0027] See appendix Figure 1-3 In this embodiment, a compact ink delivery roller device includes an ink disk 1 and an ink delivery roller 2. The ink disk 1 is mounted on a mounting frame 3. The ink delivery roller 2 is connected to a driven gear 4. The driven gear 4 is driven by a driving gear 5. The driving gear 5 is driven by an ink delivery power source 6.

[0028] The mounting frame 3 has a rack 11 below it, which meshes with an adjusting gear. The adjusting gear is connected to an adjusting power source. The ink delivery roller 2 is connected to a bearing 7. The lifting seat 8 has a through groove 13 for accommodating the bearing 7. A pin 14 is provided at the opening of the through groove 13. The two side walls of the through groove 13 have pin holes for the pin 14 to pass through. The lifting seat 8 is connected to the output shaft of the lifting cylinder 9. The lifting cylinder 9 is connected to the mounting frame 3. The driving gear 5 and the ink delivery power source 6 are both mounted on the gear seat 10. The gear seat 10 is mounted on the main body of the lifting cylinder 9. A transition gear 12 is connected between the driving gear 5 and the driven gear 4. The transition gear 12 is mounted on the gear seat 10. The lifting seat 8 is connected to a protective cover 16 by fasteners 15. The protective cover 16 has a U-shaped opening for the ink delivery roller 2 to pass through.

[0029] In this embodiment, during cleaning, the printing roller can move to create space for the ink delivery roller 2 to rise and fall, or the mounting frame 3 can descend. During work preparation, the power source (not shown in the figure) is adjusted to drive the rack 11 to rise and fall through the gear (not shown in the figure). The mounting frame 3 drives the ink delivery roller 2 and the ink tray 1 closer to the printing roller. When disassembling the ink delivery roller 2, first unscrew the fastener 15, remove the cover 16, and then pull out the pin 14. The bearing 7 leaves the slot. The power source is an electric motor, and the ink delivery power source 6 is a pneumatic motor.
