Description

Technical Field

[0001] The present invention relates to the technical field of nozzle cleaning, and particularly to an intelligent nozzle cleaning device. Background Art

[0002] Inkjet printing technology is a modern manufacturing technology that is contactless, highly efficient, and enables precise deposition of materials. With the continuous development of inkjet printing technology, its applications have expanded from the simple printing field to cutting-edge fields such as electronic manufacturing, life science, and additive manufacturing. The liquid hanging on the nozzle head during printing and the solids deposited on the nozzle plane may, on the one hand, clog the nozzle, and on the other hand, also affect the stability of ink droplet generation. Therefore, when using inkjet printing for industrial continuous production, it is necessary to regularly clean the liquid hanging on the nozzle plane and the already deposited solids. In the existing cleaning devices, the cleaning agent is likely to fly around and fall onto the surfaces of other components inside the printer during cleaning, resulting in poor printing and affecting the printing efficiency. After cleaning, it takes a certain amount of time for the cleaning agent to dry, and the cleaning efficiency is relatively low. Therefore, an intelligent nozzle cleaning device is provided to solve the above problems.

[0003] According to the comparative document (patent name: Inkjet Head Cleaning Device and Method, authorization announcement number is CN 106163813 B, application number is 202210002427.X), in this inkjet head cleaning device, the cleaning agent is likely to fly around and fall onto the surfaces of other components inside the printer during cleaning, resulting in poor printing and affecting the printing efficiency. After cleaning, it takes a certain amount of time for the cleaning agent to dry, and the cleaning efficiency is relatively low, making it inconvenient to use. Summary of the Invention

[0055] Specifically, the toothed rail 13 is meshed and connected with the gear 15. A limiting plate is arranged on the upper part of the toothed rail 13. The internal length of the sliding groove 1201 is equal to three times the length of the cleaning bin 701 or the drying bin 1001. The advantages are as follows: the gear 15 and the toothed rail 13 are provided. After the cleaning is completed, the motor five 14 is started to drive the gear 15 to rotate. The toothed rail 13 is meshed and connected with the gear 15, and the toothed rail 13 and the cleaning assembly 7 and the drying assembly 10 move backward until the drying assembly 10 is directly below the nozzle body 5. Then the motor four 1205 is started to drive the cam 1204 to rotate to lift the drying assembly 10 to contact the nozzle body 5 for drying operation. The moving effect is good. When the cam 1204 rotates, the toothed rail 13 and the gear 15 play a lateral limiting effect to ensure that the drying assembly 10 is properly contacted with the nozzle body 5. The internal length of the sliding groove 1201 is three times the length of the cleaning bin 701 or the drying bin 1001, which plays a limiting role when the cleaning bin 701 or the drying bin 1001 moves to align with the nozzle body 5.

[0056] Working principle: First, when the nozzle body 5 needs to be cleaned, the first motor 4 starts to drive the transmission component 3 to rotate, thereby driving the nozzle body 5 to move, and the nozzle body 5 is conveyed above the cleaning component 7. Then, the fourth motor 1205 is started to drive the cam 1204 to rotate until the protruding end of the cam 1204 is in horizontal contact with the lower end of the cleaning component 7. At this time, the upper end of the cleaning component 7 is in tight contact and sealed with the lower end of the nozzle body 5. The first water pump 802 is started to evenly spray the cleaning liquid in the liquid storage tank 803 onto the first cleaning brush 703 through the liquid inlet pipe 801. The second motor 706 is started to drive the first cleaning brush 703 and the first brush head 704 to rotate to clean the inkjet port 6. After the cleaning is completed, the fifth motor 14 is started to drive the gear 15 to rotate. The tooth rail 13 is meshed and connected with the gear 15, and the tooth rail 13, the cleaning component 7, and the drying component 10 move backward until the drying component 10 is directly below the nozzle body 5. The fourth motor 1205 is started to drive the cam 1204 to rotate to lift the drying component 10 into contact with the nozzle body 5. The third motor 1006 is started to drive the second cleaning brush 1003 and the second brush head 1004 to rotate and contact the inkjet port 6 that has been cleaned to sweep off the remaining liquid on the inkjet port 6. At the same time, the fan 1008 and the heat pipe 1007 are started to generate a hot air flow below the inkjet port 6 to improve the air-drying efficiency of the inkjet port 6. At the same time, the second water pump 902 is started to generate suction to suck the waste water into the waste liquid tank 903 to complete the cleaning process. This nozzle intelligent cleaning device is provided with a first sealing gasket 702 and a second sealing gasket 1002 made of soft rubber material, which has a good sealing effect and can prevent the cleaning liquid from splashing during the cleaning and drying operations. The first brush head 704 and the second brush head 1004 made of heat-resistant silica gel material are provided. The material texture is relatively soft and will not damage the inkjet port 6 when contacting the inkjet port 6, and has a good adsorption property for the ink, improving the cleaning effect. Multiple bifurcated nozzles are provided at the front end of the liquid inlet pipe 801. When in use, the cleaning liquid is evenly sprayed, which is convenient for the first brush head 704 to evenly clean the inkjet port 6, with a large cleaning area and a good cleaning effect.
