[0002] Printing is a process of transferring ink onto the surfaces of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, ink application, and pressing for originals like text, pictures, photos, anti-counterfeiting, etc. When a printing press prints various patterns, colors, text, etc. on the surface of materials to be printed (such as wrapping paper, plastic film), if there is dust adsorbed on the surface of the printing material, it is likely to affect the printing effect. Therefore, a dust reduction device for printing materials is needed.

[0003] A dust removal device for printing production disclosed in Chinese Patent CN214027782U includes a box body. Inside the box body, a first sponge roller, a second sponge roller, a first brush roller, and a second brush roller are rotatably connected. The dust attached to the upper and lower surfaces of the printing material is swept up by the first brush roller and the second brush roller, and then sorted out by the first sponge wipe and the second sponge wipe.

[0004] This dust removal device is provided with an exhaust fan. The exhaust fan extracts the floating dust through the first air duct, the second air duct, the air extraction cylinder, and the third air duct, and adsorbs it through the clear water in the water storage tank. When the first brush roller and the second brush roller clean the dust on the surface of the printing material, dust will remain in the brush gaps of the brush rollers, and it is not easy for the air extraction equipment to extract the dust in the brush roller gaps, resulting in a not-so-good cleaning effect.

[0041] Driving assemblies are arranged on both brush rollers 9, and when the brush rollers 9 rotate, the driving assemblies respectively drive the corresponding shunt pipes 16 to swing.

[0044] In the initial state, the upper exhaust ducts 13 are fixed to the bottoms of the corresponding shunt pipes 16, and the lower exhaust ducts 13 are fixed to the tops of the corresponding shunt pipes 16. As a result, the upper exhaust ducts 13 will suck away the dust on the upper surface of the printing material, and the lower exhaust ducts 13 will suck away the dust on the lower surface of the printing material.

[0045] Working principle:

[0046] During use, water is passed into the interior of the water tank 4 through the water inlet pipe 401, and the water level exceeds the air outlet end of the second connecting pipe 8 located in the water tank 4, so that the gas discharged from the second connecting pipe 8 can enter the water.

[0047] Start the first motor 5, the second motor 11, and the air pump 7.

[0048] The first motor 5 drives the rotating shaft connected thereto to rotate, causing the corresponding brush roller 9 to rotate and the corresponding gear 12 to rotate. Since the two gears 12 are meshed, the two gears 12 rotate synchronously, causing the two rotating shafts to rotate synchronously and the two brush rollers 9 to rotate synchronously, and the rotating directions of the two brush rollers 9 are opposite.

[0049] The rotating shaft will drive the lever 14 to rotate. When the lever 14 rotates, it will push the corresponding stop lever 15. Under the action of the thrust, the stop lever 15 will drive the shunt pipe 16 to rotate, causing the torsion spring to be torsionally deformed. When the lever 14 rotates away from the corresponding stop lever 15, under the action of the torsion force of the torsion spring, the stop lever 15 rotates towards the initial position. Then, by repeatedly pushing the stop lever 15 through the lever 14 and under the action of the torsion spring, the shunt pipe 16 swings reciprocally.

[0050] When the shunt pipe 16 swings, it will drive the corresponding exhaust duct 13 to swing, and the exhaust duct 13 will swing towards the corresponding brush roller 9, causing the exhaust duct 13 to extend between the bristles 901 and push the bristles 901.

[0051] The two second motors 11 respectively drive the corresponding sponge rollers 10 to rotate, and the rotating directions of the output shafts of the two second motors 11 are opposite, so that the rotating directions of the two sponge rollers 10 are opposite.

[0052] The air pump 7 sucks air through the first connecting pipe 6, the rotary joint, the shunt pipe 16, and the exhaust duct 13. The exhaust duct 13 will extract the gas at the corresponding brush roller 9 and extract the gas in the box body 1. Moreover, when the exhaust duct 13 swings, it will suck away the gas between the bristles 901.

[0053] The extracted gas enters the second connecting pipe 8, and the second connecting pipe 8 discharges the gas into the water in the water tank 4. The gas in the water is discharged to the top of the water tank 4, and finally the gas is discharged through the pressure relief valve 402.

[0054] The printed material enters the box body 1 through the first through groove 3, and the printed material will pass between two brush rollers 9, between two shunt pipes 16, between two sponge rollers 10, and finally is discharged through the second through groove 2.

[0055] The two brush rollers 9 respectively clean the top and bottom surfaces of the printed material, and the dust after cleaning is sucked away through the corresponding air extraction cylinders 13. Moreover, since the air extraction cylinder 13 will extend between the bristles 901 and push the bristles 901 when swinging, the air extraction cylinder 13 can suck away the dust between the bristles 901. The dust residue on the bristles 901 is reduced, making the cleaning effect better. Since the air extraction cylinder 13 is fan-shaped, the air extraction cylinder 13 can continuously extract air from the surface of the printed material when swinging.

[0056] The two sponge rollers 10 will clean the printed material after cleaning.

[0057] Since the gas sucked away by the air extraction cylinder 13 contains dust, the dust will enter the water along with the second connecting pipe 8, and the dust mixed in the gas is mixed with the water to achieve the purpose of dust reduction. After dust reduction, the gas is discharged from the pressure relief valve 402.

[0058] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
