Technical Field
[0001] This utility model relates to the field of ink scraping maintenance technology, specifically to an ink scraping maintenance mechanism for inkjet head assemblies of printing presses. Background Technology
[0002] A wiper is a device used to maintain and clean the printhead of an inkjet printer. Its main function is to physically remove ink residue from the printhead, preventing the ink from drying and clogging the printhead, thereby ensuring print quality and the normal operation of the printer.
[0003] Authorized announcement number CN218463302U discloses a doctor blade mechanism for an offset printing machine, including a support base. A printing roller is rotatably mounted between two support bases. A fixed base is provided on one side of the support base, and a guide seat is fixedly mounted on one side of the fixed base. By installing the guide seat on the fixed base on one side of the support base, and installing a doctor blade at the front end of the guide seat, the front end of the doctor blade is positioned below one side of the printing roller. At the same time, an inclined guide groove is opened at the upper end of the doctor blade, so that the excess ink scraped from the printing roller by the doctor blade can be discharged through the guide groove. A storage groove is opened on the guide seat. When excess ink cannot be discharged in time through the guide groove, it is guided into the storage groove by the guide seat for storage. Thus, the doctor blade mechanism with this structure can guide the ink scraped by the doctor blade, thereby avoiding ink splashing during the doctor blade process.
[0004] Based on existing technical solutions and actual production and processing, current ink scraping maintenance mechanisms still have the following drawbacks: It is inconvenient to apply cleaning fluid to the inkjet head during use, making it difficult for the device to clean and scrape off the solidified ink stains on the inkjet head surface, thus reducing the cleaning effect. Furthermore, it is inconvenient to collect and process the scraped ink during use, causing the fallen ink to easily remain on the device surface, affecting maintenance and cleaning costs and reducing cleaning efficiency. Therefore, this utility model provides an ink scraping maintenance mechanism for printing press inkjet head assemblies to solve the above-mentioned problems. Utility Model Content

[0014] In one possible implementation, the second positioning block is engaged with the sealing ring.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The ink scraping maintenance mechanism for the inkjet head assembly of this printing press facilitates the application of cleaning fluid to the inkjet head during use, making it easier to clean and scrape off solidified ink stains on the inkjet head surface, improving the cleaning effect. Simultaneously, it facilitates the collection and processing of scraped ink during use, preventing fallen ink from accumulating on the device surface, reducing maintenance and cleaning costs, and improving cleaning efficiency, resulting in a better overall performance. Specific details are as follows:
[0016] The drive motor, in conjunction with the drive rod, pushes the mounting plate and connecting block to move horizontally along the guide rod inside the support frame, so that the scraping head can apply the absorbed cleaning liquid to the surface of stubborn ink stains to soften and clean them, thereby improving the cleaning effect of the device.
[0017] The collection trough is fixed to the upper side of the mounting plate by the third positioning block and the limiting rod, so that the collection trough can collect and process the fallen ink stains, making it easier for the device to collect and recycle the fallen ink stains, reducing material consumption and cleaning costs of the device.
[0018] By using the second positioning block in conjunction with the sealing ring to seal the connection gap between the scraper and the support frame, the liquid inside the storage tank is less likely to dry out quickly or leak outwards during use, thus improving the stability of the device.

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.
[0026] Please see Figure 1-5 This utility model provides a technical solution: a scraper maintenance mechanism for inkjet head assembly of a printing press, comprising: a support frame 1, and a mounting plate 3 disposed inside the support frame 1, and further comprising:
[0027] The drive assembly 2 is installed inside the support frame 1. The mounting plate 3 has a first positioning block 4 inside, and a scraping plate 5 is installed inside the first positioning block 4. The scraping plate 5 has an extraction machine 6 inside, and an infusion pipe 7 is installed on the upper side of the extraction machine 6. An application scraping head 8 is installed on the upper side of the infusion pipe 7. The lower end of the scraping plate 5 has a suction pipe 9, and a liquid storage tank 10 is opened on the lower side of the suction pipe 9. The lower end of the mounting plate 3 has an inlet pipe 11, and the outer side of the mounting plate 3 has a collection tank 14. The lower end of the collection tank 14 has a third positioning block 15, and a limit rod 16 is installed on the upper side of the collection tank 14, thus forming a complete ink scraping maintenance mechanism.
[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly 2 includes a drive motor 201 mounted on the rear right side of the support frame 1, and a drive rod 202 connected to the left side of the drive motor 201. A connecting block 203 is provided in the middle of the drive rod 202, and a guide rod 204 is provided at the front end of the support frame 1. The drive rod 202 and the connecting block 203 are threadedly connected, and the connecting block 203 is symmetrically arranged about the central axis of the support frame 1. The guide rod 204 is slidably arranged relative to the connecting block 203, and the longitudinal section of the guide rod 204 is an "I" shaped structure. During the process, the drive motor 201 drives the drive rod 202 to rotate on the rear side of the support frame 1, so that the drive rod 202 pushes the connecting block 203 and the mounting plate 3 to move horizontally along the first positioning block 4 on the inner side of the support frame 1. At this time, the mounting plate 3 drives the scraper 5 and the smearing scraper head 8 to scrape and clean the inkjet head. At the same time, the extractor 6, together with the suction pipe 9, transports the cleaning liquid stored in the liquid storage tank 10 upward, so that the smearing scraper head 8 absorbs the cleaning liquid and applies it to the surface of stubborn ink stains to soften and clean them, thereby improving the cleaning effect of the device.
[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the collection tank 14 and the third positioning block 15 are engaged with each other, and the limiting rod 16 is threadedly connected to both the collection tank 14 and the mounting plate 3. During the use of the device, the ink stains are scraped off to the outside by the scraping head 8, so that the collection tank 14 can collect and process the fallen ink stains, making it easier for the device to collect and recycle the fallen ink stains, reducing material consumption and cleaning costs of the device.
[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the first positioning block 4 is engaged with the scraping plate 5, and the first positioning block 4 is symmetrically arranged about the central axis of the scraping plate 5. A second positioning block 12 is provided on the outer side of the scraping plate 5, and a sealing ring 13 is provided at the lower end of the second positioning block 12. The second positioning block 12 and the sealing ring 13 are engaged with each other. By installing the sealing ring 13 along the second positioning block 12 on the outer side of the scraping plate 5, the scraping plate 5 is then installed along the first positioning block 4 on the upper side of the mounting plate 3. This allows the scraping plate 5 and the mounting plate 3 to clamp the sealing ring 13 between them. At this time, the sealing ring 13 seals the connection between the scraping plate 5 and the mounting plate 3, preventing the liquid inside the liquid storage tank 10 from drying out quickly or leaking to the outside during use, thus improving the stability of the device.
