Description

Technical Field

[0001] This utility model belongs to the field of 3D printer technology, specifically relating to a waste ink collector for a 3D printer. Background Technology

[0002] During the operation of a 3D inkjet printer, the printhead precisely jets printing material onto the printing platform, and the leveling roller then meticulously smooths the printing material. However, during this process, printing ink easily adheres to the leveling roller and the area around the nozzles of the printhead. If this residual ink is not cleaned in time, it will seriously contaminate the critical components inside the printing equipment. For example, nozzle clogging will cause uneven ink droplet ejection, which will lead to problems such as "ink dripping" and "ink leakage" that seriously affect the printing quality during subsequent printing. To effectively solve this problem, a scraper is usually installed in the equipment to specifically scrape the roller surface of the leveling roller and the area around the nozzles of the printhead. The scraped-off waste ink is then guided to the waste ink collector.

[0003] Currently, most 3D inkjet printers use bolt-fixed blades, where the blade is mounted on the blade holder, which is then fixed to a designated position on the printer. However, this method has significant drawbacks: the blade edge wears down over time, reducing its cleaning effectiveness and requiring regular maintenance, replacement, or cleaning. These operations necessitate first removing the bolts from the blade holder to remove it from the printer before the blade can be detached. This cumbersome process prolongs printer downtime and reduces printing efficiency. To address these issues, this application proposes a waste ink collector for 3D printers. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a waste ink collector for 3D printers, which is characterized by easy blade replacement and maintenance.

[0014] The bottom of the fixed box has a limiting hole for inserting the U-shaped lifting frame.

[0015] Preferably, a mounting rod is fixed to the top of the movable block, and the top end of the mounting rod passes through the U-shaped lifting frame and is fixed with a fixing plate;

[0016] The outer wall of the mounting rod is fitted with a second return spring. The top end of the second return spring is connected to the bottom of the fixing plate, and the bottom end is connected to the top of the U-shaped lifting frame.

[0030] 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.

[0031] Example

[0032] Please see Figures 1-5The present invention provides the following technical solution: a waste ink collector for a 3D printer, including a mounting frame 1, a mounting groove 2 on the mounting frame 1, a support frame 3 and a blade holder 5 inside the mounting groove 2; a leveling roller body 4 is rotatably connected to the support frame 3, and a scraper body 6 for scraping the outer surface of the leveling roller body 4 is provided on the blade holder 5; two sets of connecting components are provided on both sides of the blade holder 5 for detachably installing the blade holder 5 in the mounting groove 2 of the mounting frame 1;

[0033] The connecting assembly includes a pair of positioning holes 19 formed in the mounting slot 2, and a fixed housing 7 is provided on one side of the tool holder 5; a pair of moving rods 8 are horizontally passed through the fixed housing 7, and the moving rods 8 can be inserted into the positioning holes 19; a moving block 9 is fixed to the part of the moving rod 8 inside the fixed housing 7, and a pair of insertion holes 21 are formed on one side of the moving block 9; a first return spring 10 is fitted on the outer side of each moving rod 8, and the two ends of the first return spring 10 abut against the moving block 9 and the inner wall of the fixed housing 7, respectively.

[0034] In use, when it is necessary to move the blade holder 5 into the mounting slot 2 of the mounting bracket 1, an inward pushing force is applied to the single-sided moving block 9. The first return spring 10 is compressed and deformed. The moving block 9 drives the moving rod 8 back into the through hole on the fixed housing 7. Then, the blade holder 5 is placed in the mounting slot 2 so that the positioning hole 19 corresponds to the moving rod 8. The moving block 9 is released, the first return spring 10 is reset, and the moving block 9 is pushed to move, causing one end of the moving rod 8 to be inserted into the positioning hole 19, thereby realizing the quick installation of the blade holder 5. When it is necessary to disassemble the blade holder 5, the same pushing force is applied to the single-sided moving block 9 to move the moving rod 8 out of the positioning hole 19, and the blade holder 5 can be removed from the mounting slot 2. The operation is convenient, effectively shortens the printer's downtime for maintenance, and improves printing efficiency.

[0035] Preferably, by Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, a U-shaped lifting frame 11 is vertically slidably connected to the movable block 9; guide rods 13 are welded to both sides of the movable block 9, and guide grooves 12 that slide with the guide rods 13 are opened on both side walls of the U-shaped lifting frame 11. The guide rods 13 slide along the guide grooves 12 to ensure that the U-shaped lifting frame 11 rises and falls vertically; a limiting hole 14 is opened at the bottom of the fixed box 7 for the bottom of the U-shaped lifting frame 11 to be inserted, and the vertical height of the U-shaped lifting frame 11 is greater than the vertical height of the fixed box 7 to ensure that the top of the U-shaped lifting frame 11 can extend out of the fixed box 7 for easy operation;

[0036] Preferably, by Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, a mounting rod 15 is fixed to the top of the movable block 9. The top end of the mounting rod 15 passes through the U-shaped lifting frame 11 and is fixed with a fixing plate 17. A second return spring 16 is sleeved on the outer wall of the mounting rod 15. The top end of the second return spring 16 is connected to the bottom of the fixing plate 17, and the bottom end is connected to the top of the U-shaped lifting frame 11. When the movable rod 8 is inserted into the positioning hole 19, the first return spring 10 is in the initial state (uncompressed), and its thrust acts directly on the movable block 9, so that the movable rod 8 tightly abuts against the inner wall of the positioning hole 19, thereby achieving a stable fixation of the movable rod 8. At this time, the U-shaped lifting frame 11 is in the state of being disengaged from the limiting hole 14, and the second return spring 16 remains in a compressed state due to the position of the U-shaped lifting frame 11.

[0037] When the moving rod 8 disengages from the positioning hole 19, the moving block 9 drives the U-shaped lifting frame 11 to move towards the limiting hole 14. After the U-shaped lifting frame 11 is aligned with the limiting hole 14, the second return spring 16 releases pressure (resets), pushing the U-shaped lifting frame 11 downward to insert into the limiting hole 14. The position of the moving rod 8 is indirectly fixed by the fixed moving block 9, preventing the moving rod 8 from accidentally resetting under the pushing force of the first return spring 10. This ensures that the tool holder 5 can be stably removed during disassembly. During subsequent installation, simply pull the U-shaped lifting frame 11 upward to disengage from the limiting hole 14, and the first return spring 10 can push the moving rod 8 back into the positioning hole 19.

[0038] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, inclined grooves 20 are provided on both sides of the movable block 9 to facilitate the insertion of fingers into the fixed box 7 to push the movable block 9. Arc-shaped openings 18 are provided on both sides of the fixed box 7 to provide space for finger operation.

[0039] Preferably, by Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the length of the moving rod 8 is greater than the horizontal length of the fixed box 7, ensuring that the moving rod 8 can fully extend and be inserted into the positioning hole 19.

[0040] Components not described in detail in this article are existing technologies.

[0041] The working principle and usage process of this utility model are as follows: When the 3D printer is started, the print head sprays printing material onto the printing platform. The leveling roller body 4 rotates accordingly to level the printing material. During this process, excess printing ink will adhere to the outer surface of the leveling roller body 4. As the leveling roller body 4 continues to rotate, the scraper body 6 on the blade holder 5 comes into close contact with the outer surface of the leveling roller body 4. In the relative movement between the two, the scraper body 6 scrapes off the ink adhering to the surface of the leveling roller body 4. The scraped waste ink slides down along the scraper body 6 and the blade holder 5 under the action of gravity and is finally collected in the preset waste ink collection area (not shown in detail because it belongs to the prior art), realizing the centralized collection of waste ink and avoiding waste ink contamination of other parts of the equipment.

[0042] When the scraper body 6 needs to be replaced or cleaned, the operation procedure is as follows: First, pull the U-shaped lifting frame 11 upward so that its bottom is disengaged from the limiting hole 14. The second return spring 16 is compressed. Insert your finger through the arc-shaped opening 18 and press it against the inclined groove 20 of the moving block 9. Apply an inward pushing force to the moving block 9. The first return spring 10 is compressed. The moving block 9 drives the moving rod 8 to be pulled out from the positioning hole 19. While the moving block 9 moves, it drives the U-shaped lifting frame 11 to move synchronously. When the moving rod 8 is completely disengaged from the positioning hole 19, the U-shaped lifting frame 11 moves just above the limiting hole 14. The second return spring 16 releases the pressure and pushes the U-shaped lifting frame 11 downward into the limiting hole 14 to fix the position of the moving block 9 and the moving rod 8. At this time, the fixed relationship between the blade holder 5 and the mounting bracket 1 is released. The blade holder 5 can be taken out from the mounting groove 2 to replace or clean the scraper body 6.

[0043] After the operation is completed, simply reinstall the tool holder 5 back into the mounting slot 2 according to the above installation steps. The entire process does not require tools, enabling quick disassembly and assembly of the tool holder 5, shortening maintenance time, and ensuring the printing quality of the equipment.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
