Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a printer nozzle cleaning and drying mechanism. Background Art

[0002] A printer is one of the output devices of a computer. It is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element hits the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] The basic working principle of an inkjet printer is to first generate small ink droplets, and then use the inkjet head to guide the tiny ink droplets to the set position. The smaller the ink droplets, the clearer the printed image.

[0004] When the printer is in use, the inkjet head is prone to clogging. For example, tiny objects in the ink enter the nozzle and block the ink outlet, or when the printer has not been used for a long time, the ink dries up in the inkjet head and causes clogging. In addition, some inks have poor defoaming properties and bubbles will be generated in the ink. Once the bubbles enter the nozzle, it is difficult for them to come out, causing air blockage. When the printer uses inks of different properties, inks of different properties may also cause chemical reactions, causing colloids to block the nozzle.

[0005] A clogged printer nozzle will directly reduce the quality of printing, such as the appearance of horizontal lines or blurred printing, which not only wastes paper but also affects the normal operation of the work. Therefore, the printer nozzle needs to be cleaned regularly. When the clog is serious, the nozzle cleaning program that comes with the printer has a poor cleaning effect on the nozzle. In the prior art, when cleaning and drying a seriously clogged printer nozzle, the ink cartridge is usually removed, and then the inkjet head is soaked in alcohol for a period of time to dissolve the ink in the nozzle and flow out. However, this method of cleaning the nozzle requires that the alcohol liquid level can only soak the nozzle but not enter the ink cartridge, and the soaking of the print head takes a long time, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0006] The utility model provides a printer nozzle cleaning and drying mechanism, which solves the problem in the prior art that when cleaning a seriously clogged printer nozzle, the ink cartridge and the nozzle need to be manually removed for manual cleaning, which is inefficient and requires attention to protecting the ink cartridge from being contaminated by cleaning agents.

[0007] The technical solution of the utility model is as follows:

[0043] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] like Figure 1 to Figure 5 As shown, this embodiment proposes a printer nozzle cleaning and drying mechanism, which is applied to a printer body 1, and also includes a nozzle 2, a liquid storage mechanism, a liquid storage box 3, a cleaning mechanism, a suction cup 4 and a starting component. The nozzle 2 is fixedly connected to the printer body 1, the liquid storage mechanism is installed in the printer body 1, the liquid storage box 3 is slidably connected to the printer body 1, the liquid storage box 3 is located below the nozzle 2, the cleaning mechanism is installed at the bottom end of the liquid storage box 3, a plurality of suction cups 4 are provided, and a plurality of suction cups 4 are slidably connected in the liquid storage box 3, and the starting component is installed at the bottom end of the liquid storage box 3. When the nozzle 2 is blocked, alcohol is injected into the liquid storage box 3 to clean the nozzle 2. To clean the nozzle 2, then start the component, move the liquid storage box 3 to the bottom of the nozzle 2, start the cleaning mechanism, make the suction cup 4 close to the inner wall of the printer body 1 around the nozzle 2, the part where the suction cup 4 contacts the inner wall of the printer body 1 is made of rubber material, and has a certain sealing performance, and then the cleaning mechanism presses the alcohol in the liquid storage box 3 into the nozzle 2, the amount pressed is small, and the amount is controlled not to enter the ink cartridge, and then the alcohol is sucked out and pressed into the nozzle 2 again, and the nozzle 2 is repeatedly cleaned. The alcohol evaporates quickly, and the nozzle 2 dries quickly, and finally the nozzle 2 is cleaned with higher efficiency.

[0045] Among them, the liquid storage mechanism includes an input pipe 5 and an electric valve 6. There are multiple input pipes 5, and the multiple input pipes 5 are slidably connected in the liquid storage box 3. There are multiple electric valves 6, one end of each input pipe 5 is connected to an electric valve 6, and the other ends of the multiple electric valves 6 are connected to the suction cup 4. During operation, alcohol enters the nozzle 2 through the input pipe 5. When the nozzle 2 is blocked too seriously, the electric valve 6 can be closed to prevent the alcohol from returning to the input pipe 5 and stay in the nozzle 2 for a period of time to soak the blocked nozzle 2.

[0046] Secondly, the cleaning mechanism comprises a mounting plate 7, a rubber plug 8, a push rod 9, a cylinder 10 and a liquid inlet assembly. There are multiple mounting plates 7, and the bottom end of each input tube 5 is fixedly connected to a mounting plate 7. There are multiple rubber plugs 8, and each input tube 5 is slidably connected to a rubber plug 8. There are multiple push rods 9, and each input tube 5 is slidably connected to a push rod 9, and each push rod 9 is fixedly connected to a rubber plug 8. There are multiple cylinders 10, and multiple cylinders 10 are fixedly mounted on the mounting plate 7. The output ends of multiple cylinders 10 are fixedly connected to the push rod 9. The liquid inlet assembly is mounted on the liquid storage box 3. When working, the cylinder 10 is started, and the cylinder 10 pushes the push rod 9 and the rubber plug 8 to slide in the input tube 5, and then the push rod 9 and the rubber plug 8 are pulled back. Alcohol is sucked into the suction cup 4 and the input tube 5 through the liquid inlet assembly, and the push rod 9 and the rubber plug 8 are pushed again, and the alcohol is squeezed into the nozzle 2 to clean the nozzle 2. The alcohol will not splash into the printer body 1, and the efficiency is higher.

[0047] Again, the starting component includes a rack 11, a gear 12 and a motor 13.

The output end of the motor 13 is fixedly connected to the gear 12. The starting component is used to send the liquid storage box 3 and the cleaning mechanism to the position of the nozzle 2. The motor 13 is started first, driving the gear 12 to start, thereby driving the rack 11 meshing therewith to slide, and driving the liquid storage box 3 to move.

[0048] Among them, the liquid inlet component includes a liquid inlet pipe 14 and a one-way valve 15. The liquid inlet pipe 14 is connected to the bottom end of the suction cup 4, and the one-way valve 15 is connected to the liquid inlet pipe 14. Under the action of the cleaning mechanism, alcohol enters the suction cup 4 and the input pipe 5 from the liquid storage box 3 through the one-way valve 15. Then, when the cleaning mechanism pushes the alcohol into the nozzle 2, due to the setting of the one-way valve 15, the alcohol will not flow back into the liquid storage box 3.

[0049] Finally, a notch is provided on one side of the liquid storage box 3 close to the nozzle 2 to match the shape of the nozzle 2 so that the liquid storage box 3 can be smoothly moved under the nozzle 2 .

[0050] In this embodiment, when the nozzle 2 needs to be cleaned, the motor 13 is first started, driving the gear 12 to rotate, thereby driving the rack 11 to move, moving the liquid storage box 3 to the bottom of the nozzle 2, and the suction cup 4 is pressed against the inner wall of the printer body 1 around the nozzle 2. Then the cylinder 10 is started, driving the push rod 9 to push the rubber plug 8 to move, and alcohol is sucked into the suction cup 4 and the input tube 5. Then the cylinder 10 pushes the push rod 9 and the rubber plug 8, and the alcohol is pressed into the nozzle 2 under the action of pressure. Then the cylinder 10 extracts the push rod 9 and the rubber plug 8, thereby extracting the alcohol again, and then pushes the push rod 9 and the rubber plug 8 again, and the alcohol is pressed into the nozzle 2 again, and the nozzle 2 is repeatedly cleaned.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
