Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, specifically to a support component for 3D printing. Background Technology

[0002] The support component used in 3D printing is the printing table. A 3D printer is a machine that uses rapid prototyping technology. It is a technology that uses a digital model file as a basis and employs powdered metal or plastic and other bondable materials to construct objects on the printing table by printing layer by layer.

[0003] As disclosed in authorization announcement number CN209599880U, a 3D printing table capable of rapid cleaning includes a printing table body, in which a platform is installed. A cleaning groove is formed on the upper surface of the platform, and a limiting groove is formed on one side of the upper surface of the platform, located to one side of the cleaning groove. A threaded post is fixedly connected to one end of the platform, and fixed threaded holes are formed at all four corners of the platform. The beneficial effects of this utility model using the above technical solution are: rapid cleaning with excellent cleaning effect.

[0004] Although the aforementioned patent allows for rapid cleaning, the limiting plate rotates around an axis while the scraper moves horizontally. When the limiting plate rotates to a certain angle, there is motion interference between the two, resulting in cleaning dead corners on the printing table. Utility Model Content

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A support component for 3D printing includes a printing table 1, with a horizontal bar 2 movably mounted on its upper end. A cleaning mechanism is provided below the horizontal bar 2. The cleaning mechanism includes a rubber scraper 14 horizontally fixed to the lower back of the horizontal bar 2 and triangular scraper heads 15 fixed at equal intervals to the lower front of the horizontal bar 2. A stop bar 16 is fixedly connected to both sides of the top of the printing table 1. A fixed seat 11 is fixedly connected to the top of the movable block 5. Bolts 12 are threaded to both ends of the horizontal bar 2. A threaded groove 13 matching the bolts 12 is opened at the top of the fixed seat 11. A horizontal pulling mechanism cooperates with the cleaning mechanism.

[0027] In this embodiment, the detachable threaded connection between the horizontal bar 2 and the fixed base 11 facilitates quick disassembly and replacement of easily damaged parts such as the rubber scraper 14 or the triangular scraper head 15, significantly reducing equipment maintenance costs.

[0028] like Figure 3 and Figure 4 As shown, the rod base 3 is fixedly connected to the four corners of the printing table 1. A horizontal pulling mechanism is provided between each pair of rod bases 3. The horizontal pulling mechanism includes a guide rod 4 fixed horizontally between the two rod bases 3 and a movable block 5 movably sleeved outside the guide rod 4. The bottom end of the movable block 5 is fixedly connected to a bushing 6. The bottom end of the front rod base 3 is fixedly connected to a bushing 7. The front of the bushing 6 is fixedly connected to a horizontal pull rod 8. The ends of the two pull rods 8 away from the bushing 6 pass through the bushing 7 and are connected to a handle 9. A spring 10 is movably sleeved between the bushing 7 and the bushing 6 and outside the pull rod 8.

[0029] In this embodiment, the synchronous horizontal linear movement of the rubber scraper 14 and the triangular scraper head 15 is achieved through the use of the horizontal pulling mechanism and the rigid connection of the horizontal bar 2, making the cleaning operation more convenient and efficient, completely eliminating the cleaning dead corners on the surface of the printing table 1, and solving the problem of incomplete removal of residual materials caused by structural interference in the prior art.

[0030] Working principle: When support cleaning is required, the operator pulls the lever 8 outward through the handle 9. The lever 8 drives the movable block 5 to move outward along the guide rod 4. At this time, the spring 10 is compressed and stores energy. The movable block 5 drives the fixed seat 11 to move synchronously. Since the horizontal bar 2 is fixedly connected to the threaded groove 13 at the top of the fixed seat 11 by the bolt 12, the horizontal bar 2 moves outward. The triangular scraper head 15 on the front of the horizontal bar 2 first contacts and uses its sharp edge to peel off the hard support structure on the surface of the printing table 1. Then, the rubber scraper 14 on the back of the horizontal bar 2 scrapes off the remaining soft support material through elastic deformation. The stop bar 16 limits the splash range of the scraped waste. When the handle 9 is released, the spring 10 releases its elastic force to push the bushing 6 to reset, driving the lever 8, movable block 5 and horizontal bar 2 to return to their original positions, completing one cleaning cycle. By repeatedly pulling, the support material on the surface of the printing table 1 can be completely removed.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
