[0001] This utility model relates to the technical field of air-scraper cleaning structures, specifically to an air-scraper cleaning structure for inkjet printers. Background Technology

[0002] Inkjet printers are output devices that use thermal inkjet or piezoelectric inkjet technology to spray ink droplets onto a printing medium to form text or images. They mainly consist of an external casing, control panel, and internal mechanical, electrical, and power systems. They can be classified by color, printing size, and consumable usage. Their advantages include high print quality, support for a wide range of media, low initial investment, and some support for wireless / mobile printing. Their disadvantages include slower printing speed, higher long-term operating costs, poor light and water resistance of dye-based inks, and printhead clogging that requires regular maintenance. They are widely used in home, commercial advertising, artistic creation, and clothing printing. The air scraper cleaning mechanism of an inkjet printer is an important component used to clean residual ink from the printhead surface to ensure the normal operation of the printhead.

[0003] This application improves upon the existing technology. In the existing technology, the air scraper cleaning structure of the existing inkjet printer cleans the inkjet head through a scraper in actual use. However, the scraper can generally only wipe vertically or horizontally, resulting in certain wiping dead corners on the inkjet head and poor cleaning effect. Utility Model Content

[0004] The purpose of this utility model is to provide an air-scraper cleaning structure for inkjet printers, which solves the problem that in the actual use of existing air-scraper cleaning structures for inkjet printers, the scraper can only clean the inkjet head in a vertical or horizontal direction, resulting in certain dead corners on the inkjet head and poor cleaning effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The air-scraper cleaning structure of an inkjet printer includes a printer body with a working cavity extending from its front end; a transmission assembly disposed inside the working cavity, the transmission assembly including a servo motor detachably mounted at the rear end inside the working cavity, a transmission screw fixedly connected to the output end of the servo motor, a moving block threaded on the outer wall of the transmission screw, a limit rod movably disposed through the surface of the moving block; a transmission block fixedly connected to the front end of the moving block, a telescopic cylinder fixedly mounted to the front end of the transmission block, a mounting plate fixedly connected to the output end of the telescopic cylinder, and a scraper movably disposed on the top of the mounting plate.

[0006] Preferably, the upper surface of the mounting plate extends into the interior and has a positioning groove, and a positioning block is movably disposed inside the positioning groove, with the top of the positioning block fixedly connected to the bottom of the scraper.

[0007] Preferably, a positioning hole is provided on the outer wall of the positioning block extending into the interior, and a positioning screw is threaded onto the inner wall of the positioning hole.

[0008] Preferably, a groove is provided at the top of the inner side of the working cavity, a slider is slidably disposed inside the groove, and an inkjet head is fixedly connected to the bottom of the slider.

[0010] Preferably, an anti-slip pad is fixedly connected to the bottom of the threaded sleeve, and the anti-slip pad is made of rubber.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. Through the structural design of the telescopic cylinder, scraper, mounting plate, transmission block, transmission screw, servo motor, moving block, and limit rod, the inkjet head can be easily wiped back and forth and left and right. This can effectively improve the cleaning effect of the inkjet head and solve the problem that the existing air-scraper cleaning structure of inkjet printers can only clean the inkjet head in a vertical or horizontal direction, resulting in certain dead corners on the inkjet head and poor cleaning effect.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 The air-scraper cleaning structure of the inkjet printer includes a printer body 1, and a working chamber 2 is provided inside the front end face of the printer body 1. The transmission assembly is located inside the working chamber 2. The transmission assembly includes a servo motor 14 that is detachably installed at the rear end inside the working chamber 2. The output end of the servo motor 14 is fixedly connected to a transmission screw 13. A moving block 19 is threaded on the outer wall of the transmission screw 13. A limit rod 20 is movably provided through the surface of the moving block 19. A transmission block 12 is fixedly connected to the front end face of the moving block 19, a telescopic cylinder 8 is fixedly installed on the front end face of the transmission block 12, an installation plate 11 is fixedly connected to the output end of the telescopic cylinder 8, and a scraper 10 is movably provided on the top of the installation plate 11. Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, during use, when the inkjet head 9 needs to be wiped and cleaned, the output end of the telescopic cylinder 8 can drive the mounting plate 11 to move back and forth. The movement of the mounting plate 11 drives the scraper 10 to move back and forth, thereby wiping the inkjet head 9 from front to back. The output end of the servo motor 14 can drive the transmission screw 13 to rotate. The rotation of the transmission screw 13 drives the moving block 19 to move. The movement of the moving block 19 drives the transmission block 12 to move. The movement of the transmission block 12 ultimately drives the scraper 10 to move left and right, thereby wiping the inkjet head 9 from side to side. By facilitating the wiping of the inkjet head 9 from front to back and side to side, the cleaning effect of the inkjet head 9 can be effectively improved. This solves the problem that in the actual use of the air scraper cleaning structure of existing inkjet printers, the scraper 10 can only clean the inkjet head 9 in a vertical or horizontal direction, resulting in certain wiping dead corners on the inkjet head and poor cleaning effect.

[0017] The upper surface of the mounting plate 11 extends into the interior and is provided with a positioning groove 17. A positioning block 16 is movably disposed inside the positioning groove 17, and the top of the positioning block 16 is fixedly connected to the bottom of the scraper 10. A positioning hole 15 extends into the outer wall of the positioning block 16, and a positioning screw 18 is threaded on the inner wall of the positioning hole 15. A sliding groove 7 is provided at the top of the interior of the working cavity 2, and a slider 6 is slidably disposed inside the sliding groove 7. An inkjet head 9 is fixedly connected to the bottom of the slider 6. Threaded sleeves 4 are provided at the four corners of the bottom of the printer body 1. Threaded posts 3 are threaded on the inner wall of the threaded sleeves 4, and the top of the threaded posts 3 is fixedly connected to the bottom of the printer body 1. An anti-slip pad 5 is fixedly connected to the bottom of the threaded sleeves 4. The anti-slip pad 5 is made of rubber. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, during use, the positioning screw 18 can be rotated until one end of the positioning screw 18 disengages from the positioning hole 15. Then, the scraper 10 is moved upward until the positioning block 16 disengages from the positioning groove 17, thereby completing the disassembly of the scraper 10. Similarly, the scraper 10 can be installed. By facilitating the disassembly, cleaning, and replacement of the scraper 10, its cleaning effect can be effectively guaranteed. At the same time, by appropriately rotating the threaded sleeve 4, the length of the threaded post 3 inside the threaded sleeve 4 can be adjusted, thereby facilitating the reasonable adjustment of the overall height of the printer body 1, and thus better meeting the usage needs of different scenarios.

[0018] Working principle: In this application, when the inkjet head 9 needs to be wiped and cleaned, the output end of the telescopic cylinder 8 can drive the mounting plate 11 to move back and forth. The movement of the mounting plate 11 drives the scraper 10 to move back and forth, thereby wiping the inkjet head 9 back and forth. Furthermore, the output end of the servo motor 14 can drive the transmission screw 13 to rotate. The rotation of the transmission screw 13 drives the moving block 19 to move. The movement of the moving block 19 drives the transmission block 12 to move. The movement of the transmission block 12 ultimately drives the scraper 10 to move left and right, thereby wiping the inkjet head 9 left and right. By facilitating the back-and-forth and left-and-right wiping of the inkjet head 9, inkjet output efficiency can be effectively improved. The cleaning effect of the head 9 is improved. Secondly, by rotating the positioning screw 18 until one end of the positioning screw 18 disengages from the positioning hole 15, the scraper 10 is moved upward until the positioning block 16 disengages from the positioning groove 17, thus completing the disassembly of the scraper 10. Similarly, the scraper 10 can be installed. By facilitating the disassembly, cleaning, and replacement of the scraper 10, its cleaning effect can be effectively guaranteed. At the same time, by appropriately rotating the threaded sleeve 4, the length of the threaded post 3 inside the threaded sleeve 4 can be adjusted, thereby facilitating the reasonable adjustment of the overall height of the printer body 1, and thus better meeting the usage needs of different scenarios.
