Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to an automatic cleaning device for offset printing machine blankets. Background Technology

[0002] Offset printing is a type of planographic printing machine. During printing, the printed image is first printed onto the rubber roller from the printing plate, and then transferred from the rubber roller to the paper. The rubber roller needs to be frequently changed with different types or colors of ink depending on the type of printed material. Although the surface of the rubber roller is specially treated, under high pressure and high speed, ink will still gradually stick to the surface of the roller, so it needs to be cleaned frequently.

[0003] The existing automatic cleaning device for offset printing press rubber rollers has a relatively simple structure. Generally, it uses a water tank to clean the rollers through a nozzle and a conveyor belt for transmission. During the transmission process, the rubber rollers are placed directly on the conveyor belt. The cleaning mechanism only consists of a water tank and a nozzle. During cleaning, the rubber rollers are moved out after passing under the cleaning mechanism with the conveyor belt. This cannot guarantee that the rubber blanket on the outside of the rubber rollers can be thoroughly cleaned.

[0004] To address the aforementioned technical problems, this application proposes an automatic cleaning device for offset printing press blankets. Utility Model Content

[0028] Example 1

[0029] As attached Figure 1 and attached Figure 6As shown, an automatic cleaning device for offset printing machine blankets includes a mounting frame 1. Two sets of cleaning brushes 13 are installed inside the mounting frame 1. Two sets of water baffles 19 are installed on the side wall of the mounting frame 1. The two sets of water baffles 19 are installed on both sides of the cleaning brushes 13. A motor 20 and a control switch 21 are installed on one set of water baffles 19. The control switch 21 controls the motor 20. The shaft end of the motor 20 passes through the water baffle 19 and is mounted on a mounting base 22. The end of the rubber roller 23 is fixedly installed inside the mounting base 22. The mounting base 22 has a structure of a sleeve and a tightening belt. The tightening belt tightens the sleeve and fixes the end of the rubber roller 23 inside the mounting base 22. The rubber roller 23 is located between the two sets of cleaning brushes 13 and is in contact with the two sets of cleaning brushes 13. The motor 20 drives the rubber roller 23 to rotate, and the two sets of cleaning brushes 13 clean the ink on the surface of the rubber blanket outside the rubber roller 23.

[0030] To clean the outer surface of the rubber blanket of the moving rubber rollers 23 with different radii, as shown in the attached document... Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, a horizontal plate 2 is installed on the top of the mounting frame 1, and a horizontal plate 3 is installed on the lower part of the side wall of the mounting frame 1. Angle adjustment components are respectively installed on the horizontal plate 2 and the horizontal plate 3. The angle adjustment components include an angle adjustment plate 4 and a connecting horizontal plate 5. The lower side of the angle adjustment plate 4 is rotatably connected to the side wall of the mounting frame 1, and the upper side is rotatably connected to the connecting horizontal plate 5. Hand-tightening bolts 6 pass through the horizontal plate 2 and the horizontal plate 3 respectively, and are connected by threads. Rotating the hand-tightening bolts 6 allows them to move through the horizontal plate 2 and the horizontal plate 3. The connecting horizontal plate 5 is provided with a slide 7 for the hand-tightening bolts 6 to slide through. Clamping plates 8 are installed on the outer sides of the upper and lower sides of the connecting horizontal plate 5. The hand-tightening bolt 6 is connected to the connecting horizontal plate 5 through the two sets of clamping plates 8. The hand-tightening bolt 6 slides inside the slide rail 7. The two sets of clamping plates 8 move up and down on the connecting horizontal plate 5, driving the connecting horizontal plate 5 to adjust its height. The connecting horizontal plate 5 drives the angle adjustment plate 4 to rotate. The two sets of cleaning brush plates 13 are slidably installed on the side of the angle adjustment plate 4 in the two sets of angle adjustment components that are close to each other. The connecting horizontal plate 5 drives the cleaning brush plates 13 to adjust their angle. Multiple sets of ball bearings 9 are rotatably installed on the side of the clamping plate 8 that is close to the connecting horizontal plate 5. The multiple sets of ball bearings 9 reduce the moving resistance of the clamping plate 8 on the upper and lower sides of the connecting horizontal plate 5.

[0031] As attached Figure 3 and attached Figure 7As shown, slots 10 are installed on the sides of the two sets of angle adjustment plates 4 that are close to each other. A convex insert 12 is installed at the bottom of the cleaning brush plate 13. The convex insert 12 is inserted into the slot 10. A positioning bolt 11 passes through the angle adjustment plate 4. The positioning bolt 11 is inserted into the convex insert 12 to fix the convex insert 12 inside the slot 10, which facilitates the installation and removal of the cleaning brush plate 13.

[0032] Example 2

[0033] Based on Example 1, in order to facilitate the rinsing of the rubber sheet on the outside of the rubber roller 23 and the collection of wastewater, as shown in the attached... Figure 3 and attached Figure 4 As shown, an inclined plate 14 is installed on the upper set of angle adjustment components. A spray pipe 15 is installed on the side of the inclined plate 14 near the rubber roller 23. The inclined plate 14 is installed on the side of the connecting horizontal plate 5 away from the angle adjustment plate 4. A water supply hose 16 is connected to the spray pipe 15. The water supply hose 16 is connected to a water supply pump body. Water is sent to the spray pipe 15 through the water supply hose 16. The water is sprayed onto the rubber cloth outside the rubber roller 23 through multiple sets of nozzles on the spray pipe 15 for rinsing. A U-shaped groove 17 is provided at the bottom of the mounting frame 1. A water collection frame 18 is built into the U-shaped groove 17. The rinsed water flows downward and falls into the water collection frame 18 for collection.

[0034] A waterproof cover 24 is installed on the upper side of the connecting horizontal plate 5 in the lower set of angle adjustment components. The waterproof cover 24 covers the outside of the slide 7, and the clamping plate 8 slides inside the waterproof cover 24. The waterproof cover 24 prevents water after rinsing from passing through the slide 7 and entering between the clamping plate 8 and the connecting horizontal plate 5. Impurities are trapped between the clamping plate 8 and the connecting horizontal plate 5, affecting the movement of the clamping plate 8.
