[0033] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0034] Embodiment 1:

[0035] As Figure 1-4 shown, a UV inkjet printer with an automatic dust removal function includes a machine 1, and an inkjet component 2 and a cleaning component 3 provided on the top of the machine 1.

[0036] The cleaning component 3 includes two slide blocks 4 that are drivingly and cooperatively connected to both sides of the top of the machine 1 through a driving component. A brush roller 6 is rotatably connected to the relative side of the two slide blocks 4 through a linkage component. The driving component includes a lead screw 7 and a rotating shaft 9. The lead screw 7 is rotatably connected to the inner wall of the machine 1, and one of the slide blocks 4 is in threaded cooperation with the lead screw 7, and the other slide block 4 is slidably cooperated with the inner wall of the machine 1. Belt pulleys 8 are fixedly connected to the outer walls of the lead screw 7 and the rotating shaft 9, and the same transmission belt 10 meshes with the outer walls of the two belt pulleys 8. The rotating shaft 9 is fixedly connected to a motor 11 through a coupling, and the motor 11 is fixed to the inner wall of the machine 1 by bolts.

[0037] The starting motor 11 drives the rotating shaft 9 and one of the belt pulleys 8 to rotate. The transmission belt 10 is in transmission cooperation to drive the lead screw 7 and the other belt pulley 8 to rotate, so that the slider 4 drives the brush roller 6 to move linearly, and the brush roller 6 rotates to clean the surface of the machine table 1.

[0038] By arranging the brush roller 6, the driving assembly is used to drive the brush roller 6 to move linearly back and forth. The brush roller 6 is in rolling contact with the surface of the machine table 1 to remove the dust, paper scraps and ink stains attached to the surface of the machine table 1, ensuring the normal operation of the device and the cleanliness and appearance quality of the printing material.

[0039] As Figure 5 shown, the spraying and painting assembly 2 includes two sliding plates 12 slidably fitted to the outer walls on both sides of the machine table 1 through electric slide rails. Electric push rods 13 are fixedly connected to the tops of the two sliding plates 12. The telescopic ends of the electric push rods 13 are fixedly connected with a guide plate 14, and a UV spraying and painting head 15 is slidably fitted to the guide plate 14 through an electric slide rail.

[0040] The positions of the UV spraying and painting head 15 in the horizontal direction can be adjusted by using the sliding plate 12 and the guide plate 14. The electric push rod 13 can adjust the height of the UV spraying and painting head 15. And when it is necessary to clean the surface of the machine table 1, starting the electric push rod 13 to drive the guide plate 14 and the UV spraying and painting head 15 to rise can avoid the cleaning assembly 3.

[0041] As Figure 2 shown, the same liquid storage tank 5 is detachably installed on the tops of the two sliders 4. A cover plate is installed on the top of the liquid storage tank 5 through a hinge. A plurality of liquid leakage holes are formed in the inner wall of the brush roller 6, and the brush roller 6 is communicated with the liquid storage tank 5 through a liquid infusion assembly.

[0042] The liquid storage tank 5 stores cleaning liquid, which can continuously provide cleaning liquid for the brush roller 6, further improving the cleaning effect.

[0043] As Figure 6 、 7 shown, the liquid infusion assembly includes two symmetrically arranged transition rings 16, a hose 18 and a connecting ring 19. Hollow shafts 17 are fixedly connected and communicated with the inner walls on both sides of the brush roller 6. The transition rings 16 are movably fitted to the inner walls of the hollow shafts 17, and the hollow shafts 17 are rotatably connected to the inner walls of the sliders 4.

[0044] A receiving groove is formed in the inner wall of the slider 4. The hose 18 is arranged on the inner wall of the receiving groove. The connecting ring 19 is fixedly connected to the outer wall of the hollow shaft 17, and a plurality of rollers 20 are rotatably connected to the outer wall of the connecting ring 19 through a connecting frame. The rollers 20 are in rolling extrusion cooperation with the outer wall of the hose 18.

[0045] One end of the hose 18 is fixedly connected and communicated with the liquid storage tank 5, and the other end of the hose 18 is fixedly connected and communicated with the transition ring 16.

[0046] When the brush roller 6 and the hollow shaft 17 rotate, the connecting ring 19 and all the rollers 20 rotate accordingly. The rollers 20 roll and squeeze the hose 18, extracting the cleaning liquid in the liquid storage tank 5 and transporting it through the transition ring 16 and the hollow shaft 17 to the inside of the brush roller 6, and finally flowing out through the liquid leakage holes on the brush roller 6, improving the cleanliness of the surface of the machine table 1.

[0047] Embodiment 2:

[0048] A UV inkjet printer with an automatic dust removal function. The following improvements are made to this embodiment on the basis of Embodiment 1, as Figure 1-8 shown:

[0049] The linkage assembly includes two symmetrically arranged one-way ratchets 21 and racks 22. The inner wall of the one-way ratchet 21 is fixedly connected to the outer wall of the hollow shaft 17, the outer wall of the one-way ratchet 21 meshes with the rack 22, and the rack 22 is fixedly connected to the top of the machine table 1.

[0050] When the slider 4 drives the hollow shaft 17 and the brush roller 6 to move linearly, the meshing of the one-way ratchet 21 and the rack 22 causes the one-way ratchet 21 to drive the hollow shaft 17 and the brush roller 6 to rotate. At the same time, the connecting ring 19 drives the rollers 20 to rotate and roll and squeeze the hose 18 to realize the transportation of the cleaning liquid. After cleaning, the slider 4 moves in the reverse direction and all components return to their original positions.

[0051] By setting the one-way ratchet 21 and the rack 22, the cooperation between the two enables the brush roller 6 to rotate while moving linearly with the slider 4. The rotation of the brush roller 6 can realize the automatic transportation of the cleaning liquid, reducing the layout of the power source.

[0052] Working principle: The UV inkjet head 15 is driven to move by the slide plate 12 and the guide plate 14 to realize the inkjet operation. After the inkjet is completed, the electric push rod 13 is started to drive the guide plate 14 and the UV inkjet head 15 to rise to avoid the cleaning component 3. Subsequently, the motor 11 is started to drive the rotating shaft 9 and one of the belt pulleys 8 to rotate. The transmission belt 10 is in transmission cooperation to drive the lead screw 7 and the other belt pulley 8 to rotate, so that the slider 4 drives the brush roller 6 to move linearly. When the brush roller 6 moves, due to the meshing of the one-way ratchet 21 and the rack 22, the one-way ratchet 21 drives the hollow shaft 17 and the brush roller 6 to rotate. The connecting ring 19 and the rollers 20 rotate with the hollow shaft 17. The rollers 20 roll and squeeze the hose 18, extracting the cleaning liquid in the liquid storage tank 5 and transporting it through the transition ring 16 and the hollow shaft 17 to the inside of the brush roller 6, and finally flowing out through the liquid leakage holes on the brush roller 6. The brush roller 6 performs rolling brush cleaning on the surface of the machine table 1 while moving linearly and rotating. After cleaning, the slider 4 is made to move in the reverse direction to drive all components to return to their original positions, and the number of cleaning times can be selected according to needs.

[0053] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
