[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A printhead scraping device includes a mounting frame 1, a scraping drive mechanism 2, a scraping cartridge 3, and a scraper blade 5. The mounting frame 1 is fixedly installed inside the printer; the scraper drive mechanism 2 is installed on the mounting frame 1, and the bottom of the scraper cartridge 3 is symmetrically fixedly equipped with connecting blocks 31, which are connected to the moving end of the scraper drive mechanism 2. like Figure 4 As shown, an installation structure 32 is installed on the upper side of the scraper cartridge 3, and a lower collection groove 33 is opened on the lower side of the scraper cartridge 3; a scraper blade 5 for scraping ink is installed in the installation structure 32; an adjustable flow guide mechanism 4 for adjusting the liquid flow direction is installed in the lower collection groove 33; a nozzle for cleaning the scraper blade 5 is fixedly installed on the upper side of the mounting frame 1 inside the printer.

The sealing plate 47 is symmetrically fixedly installed on the upper side of the lower collection tank 33, and the sealing strip 48 is fixedly installed at the bottom of the sealing plate 47. When the guide channel frame 41 is raised, the inner bottom of the guide channel frame 41 abuts against the sealing strip 48.

[0027] like Figure 7 As shown, a plate 51 is fixedly installed on the lower side of the scraper 5, and slots 52 are symmetrically opened on the plate 51; the plate 51 is inserted into the slot 322, and the slots 52 are engaged with the plate 324.

[0028] like Figure 2 and Figure 4 As shown, the follow-up manifold structure 6 includes a manifold component and a follow-up component; the follow-up component is installed on the ink collection box 71 and the liquid collection box 72, and the manifold component is installed on the ink collection box 71, the liquid collection box 72 and the follow-up component; The follow-up assembly includes pulleys 64, a conveyor belt 65, and a rigid pipe 66. Two pulleys 64 are symmetrically and rotatably mounted on the ink collection box 71. The conveyor belt 65 is sleeved between the two pulleys 64, and the two pulleys 64 are connected by the conveyor belt 65. One end of the rigid pipe 66 is fixedly connected to the conveyor belt 65, and the other end of the rigid pipe 66 is fixedly connected to the ink scraper box 3. The other end of the rigid pipe 66 is fixedly connected to the other end of the connecting pipe 46. The rigid pipe 66 and the connecting pipe 46 are connected. Two pulleys 64 are symmetrically and rotatably mounted on the liquid collection box 72. A conveyor belt 65 is sleeved between the two pulleys 64, and the two pulleys 64 are connected by the conveyor belt 65. The manifold assembly includes a lower fixing plate 61, an upper fixing plate 63, and a discharge pipe 67. The lower fixing plate 61 is fixedly installed on the ink collection box 71 and the liquid collection box 72 on the lower side of the conveyor belt 65. A liquid collection tank 62 is opened on the lower fixing plate 61. Both ends of the upper fixing plate 63 are rotatably connected to the pulley 64 respectively. One end of the discharge pipe 67 is fixedly connected to the lower fixing plate 61, and the other end of the discharge pipe 67 is fixedly connected to the ink collection box 71 and the liquid collection box 72. The ink collection box 71 is connected to the liquid collection tank 62 through one discharge pipe 67, and the liquid collection box 72 is connected to another liquid collection tank 62 through another discharge pipe 67.

[0029] In this embodiment, the insert plate 51 at the bottom of the scraper 5 is inserted into the slot 322. The insert plate 51 presses down on the retaining plate 324, causing the spring 323 to bend. After the insert plate 51 is fully inserted into the slot 322, the retaining plate 324 aligns with the slot 52. The spring 323 resets, causing the retaining plate 324 to engage in the slot 52, thus fixing the insert plate 51 and the scraper 5. When replacing the scraper 5, the unlocking block 327 is pressed, which drives the push block 326 and the moving block 326. The moving rod 325 moves horizontally, compressing the spring 328; the push block 326 pushes the upper side of the clamping plate 324 to move, so that the clamping plate 324 is no longer stuck in the slot 52, the scraper 5 is raised, and the insert plate 51 moves upward a certain distance, then the unlocking block 327 is released, the spring 328 returns to its original position, driving the moving rod 325 and the push block 326 to return to their original positions; at this time, the insert plate 51 is blocked on one side of the clamping plate 324; continue to pull the scraper 5 until the insert plate 51 is completely disengaged from the slot 322; The servo motor 21 drives a rotating shaft 22 to rotate through the transmission assembly 23. The rotating shaft 22 drives another rotating shaft 22 to rotate through the synchronous pulley 24 and the conveyor synchronous belt 25. This causes the conveyor synchronous belt 25 to move between the synchronous pulleys 24. The movement of the conveyor synchronous belt 25 causes the scraper cartridge 3 to move horizontally under the limiting action of the guide rod 26. This causes the scraper blade 5 to move horizontally through the mounting bracket 321 and the insert plate 51. The scraper blade 5 scrapes off the residual ink on the print head. During normal use, electromagnet 44 is off; at this time, the guide rail frame 41 tilts towards the side closer to the counterweight 42 under the gravity of the counterweight 42; this causes the scraped residual ink to flow into the guide rail frame 41, then flow to one side of the guide rail frame 41, and is collected by the collection hopper 45, and discharged into the collection tank 62 through the connecting pipe 46 and the rigid pipe 66, and then flows into the ink collection box 71 through the discharge pipe 67, where it is collected; during cleaning, electromagnet 44 is turned on, and electromagnet 44 attracts the iron block 43, causing the guide rail frame 41 to tilt to the other side; thus, during tilting... After the cleaning fluid falls into the guide trough 41, it flows to the other side and is collected by the collection hopper 45 on the other side. It is then discharged into the collection tank 62 on the other side through the connecting pipe 46 and the rigid pipe 66, and then flows into the collection box 72 through the discharge pipe 67, where it is collected. During this process, the movement of the scraper cartridge 3 drives the rigid pipe 66 to move, and the movement of the rigid pipe 66 drives the conveyor belt 65 to move between the pulleys 64. This allows the residual ink to be discharged into the collection tank 62 at any position in a timely manner, and avoids the residual ink from being exposed to the outside and causing pollution. This facilitates the subsequent collection and utilization of the residual ink.
