[0002] A laser 3D printer, also known as a selective laser sintering (SLS) 3D printer, is a special type of 3D printing technology. Its working principle involves using a high-power laser to sinter tiny powdered metal or plastic particles into a solid structure based on a 3D model. The support platform of the 3D printer, also called the printing platform, is used to hold the printing material. During printing, the laser 3D printer lays layers of powder material on the support platform, and it needs to be cleaned after printing.

[0003] Existing easy-to-clean laser 3D printer support platforms are not convenient for collecting residues during scraping and cleaning, causing them to fall around the equipment and making cleaning difficult; furthermore, they are not convenient for easy disassembly and assembly of the scraper, and damaged scrapers cannot be replaced, making the device somewhat inadequate.

[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] Reference Figures 1-6 An embodiment of this utility model provides: a laser 3D printer support platform that is easy to clean, including a housing 1, a first cylinder 2 fixedly connected to the bottom of the housing 1, a support platform body 3 fixedly connected to the top of the first cylinder 2, a second cylinder 23 fixedly connected to the side wall of the housing 1, a connecting block 17 fixedly connected to the output end of the second cylinder 23, a detachable component connected inside the connecting block 17, and a collection component connected inside the support platform body 3;

[0032] The collection component includes a collection drawer 6. The support platform body 3 has a through groove 4 and a limiting groove 5. There are four sets of through grooves 4. The collection drawer 6 is slidably connected in the limiting groove 5. A fixed rod 7 is rotatably connected to the top of the through groove 4. A turntable 8 is fixedly connected to the bottom of the fixed rod 7. An arc-shaped groove 9 is opened in the turntable 8. There are four sets of arc-shaped grooves 9. A sliding rod 10 is slidably connected in each of the four sets of arc-shaped grooves 9. A limiting plate 24 is fixedly connected to the top of the sliding rod 10. A connecting plate 11 is fixedly connected to the bottom of the sliding rod 10. A collection plate 12 is fixedly connected to one end of the connecting plate 11. The collection plate 12 slides in the through groove 4. A drive component is connected to the outside of the fixed rod 7 to facilitate the rotation of the fixed rod 7.

[0033] The detachable components include a slide plate 19, a groove 18 is provided in the connecting block 17, the slide plate 19 is slidably connected in the groove 18, a threaded groove 21 is provided on the outside of the connecting block 17, a fixing bolt 22 is threadedly connected in the threaded groove 21, a positioning hole is provided in the slide plate 19, one end of the fixing bolt 22 slides in the positioning hole, and a scraper 20 is fixedly connected to the bottom of the slide plate 19; the drive components include a worm gear 16, the worm gear 16 is fixedly connected to the outside of the fixing rod 7, a fixing block 13 is fixedly connected to the top of the through groove 4, a worm 14 is rotatably connected in the fixing block 13, and the worm 14 meshes with the worm gear 16; one end of the worm 14 passes through a set of collection plates 12 and is fixedly connected to a crank 15, the crank 15 rotates in the set of collection plates 12; the scraper 20 is parallel to the support platform body 3; the turntable 8 is parallel to the support platform body 3; the bottom of the inner side of the collection plate 12 is inclined to facilitate the collection of residual materials into the collection drawer 6.

[0034] Working principle: In the easy-to-clean laser 3D printer support platform, turning the crank handle 15 drives the worm gear 14 to rotate, the worm gear 14 drives the worm wheel 16 to rotate, the worm wheel 16 drives the fixed rod 7 to rotate, and the fixed rod 7 drives the turntable 8 to rotate. This causes the four sets of sliding rods 10 to slide in the arc groove 9, which in turn moves the connecting plate 11. This causes the four sets of collecting plates 12 to slide on the through groove 4. The second cylinder 23 is activated to drive the scraper 20 to reciprocate and scrape away the material remaining on the top of the support platform body 3. The scraper 20 then falls onto the inclined edge at the bottom of the collecting plate 12 at the edge of the support platform body 3, and then falls into the collecting drawer 6 for easy collection, preventing it from splashing around and being difficult to clean. Unscrewing the fixing bolt 22 from the threaded groove 21 allows the slide plate 19 to slide out of the sliding groove 18, making it easy to disassemble and replace the damaged scraper 20 without affecting subsequent use.

[0035] All electrical components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein.
