Description

Technical Field

[0001] The invention belongs to the technical field of inkjet printing, and more specifically, relates to a cleaning device. Background Art

[0002] Inkjet printer is a large printer series product, which uses solvent-based or UV fixed ink. Solvent-based ink has a strong odor and corrosiveness. In the printing process, the ink penetrates into the inner part of the printing material through corrosion, making the image not easy to fade. Therefore, it has the characteristics of waterproof, anti-radiation and anti-scratch. It is widely used in industries such as glass, decoration, signage, murals or display boards.

[0003] The inkjet printer sprays ink droplets of various colors onto the fabric through the nozzle to form a printed pattern. Since it uses solvent-based ink with high volatility, the ink is easy to dry, condense, and agglomerate on the nozzle hole, so that the ink cannot be sprayed out smoothly from the nozzle hole, which seriously affects the printing quality. Therefore, in order to ensure the printing quality, a scraper is usually set to scrape off the solid ink at the nozzle hole of the nozzle. After cleaning, some dirt will be attached to the scraper, such as ink, particles in the ink, residue formed by drying ink, and dust in the air covering the scraper.

[0004] Currently, in order to clean the scraper, the scraper is usually cleaned manually by using a cleaning cloth dipped in water, which is difficult to operate, time-consuming and labor-intensive, and has low cleaning efficiency.

[0005] The scraper is mounted on a synchronous belt or a chain structure, and immersed in a water tank. The scraper is driven to move back and forth by the synchronous belt or the chain structure so that the water in the water tank cleans the scraper. However, this method has the problem that the impact force of the water in the water tank on the scraper is not enough. It can only clean the liquid ink on the scraper, but it is difficult to clean the particles or residues formed after the ink solidifies on the scraper, and the cleaning effect is poor.

[0031] Please also read Figures 1 to 3, the cleaning device provided by the present invention is now described. The cleaning device is used to clean the scraper 1. It should be noted that the scraper 1 is set in the inkjet printer and the label machine. Specifically, the scraper 1 is used to scrape off the solid ink remaining at the nozzle of the inkjet printer and the nozzle of the label machine. In this embodiment, the application scenario of the scraper 1 is not limited to a single one. The scraper 1 has a first blade surface 11 and a second blade surface 12 that are relatively arranged. After the scraper 1 is cleaned, some dirt will be attached to the first blade surface 11 and the second blade surface 12, such as ink, particles in the ink, and residue formed by drying of the ink; the cleaning device includes a mounting assembly 100 and a liquid supply assembly 200.

[0032] The mounting assembly 100 is used to mount the scraper 1. The mounting assembly 100 has a first water outlet groove 110 and a second water outlet groove 120 which are arranged at intervals. The scraper 1 is arranged between the first water outlet groove 110 and the second water outlet groove 120. The first water outlet groove 110 can discharge liquid in the direction of the first blade surface 11, and the second water outlet groove 120 can discharge liquid in the direction of the second blade surface 12. Specifically, the first water outlet groove 110 and the second water outlet groove 120 are arranged at intervals. The extension direction of the first water outlet groove 110 is the same as the extension direction of the first blade surface 11, and the extension direction of the second water outlet groove 120 is the same as the extension direction of the second blade surface 12. Moreover, the notch direction of the first water outlet groove 110 faces the first blade surface 11, and the notch direction of the second water outlet groove 120 faces the second blade surface 12, so that the cleaning liquid flowing out of the first water outlet groove 110 and the second water outlet groove 120 can flow to the first blade surface 11 and the second blade surface 12 respectively.

[0033] The liquid supply assembly 200 is connected to the mounting assembly 100 and is used to supply liquid to the first water outlet groove 110 and the second water outlet groove 120.

One end of the flow guide mechanism 230 is connected to the water outlet end. The first water outlet groove 110 and the second water outlet groove 120 are both connected to the other end of the flow guide mechanism 230. Specifically, the cleaning liquid can be water or a mixed liquid. The extraction mechanism 220 can extract the cleaning liquid in the liquid storage mechanism 210 from the water inlet end and discharge it from the water outlet end to the flow guide mechanism 230. Then, the cleaning liquid is introduced from the flow guide mechanism 230 to the first water outlet groove 110 and the second water outlet groove 120 in the installation assembly 100, so as to supply liquid to the first water outlet groove 110 and the second water outlet groove 120.
