Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and specifically provides a replaceable 3D printing platform for products. Background Technique

[0002] The working principle of a 3D printer is basically the same as that of an ordinary printer. It stacks "printing materials" layer by layer through computer control, and finally turns the blueprint on the computer into a physical object. This technology is often used in the fields of mold manufacturing, industrial design, etc. to manufacture models or for the direct manufacturing of some products. The printing platform is an important part of a 3D printer and is the basic plane that bears the printed object during the printing process, directly affecting the printing quality.

[0003] During the printing process of the existing 3D printing platform for products, it is necessary to heat the printing platform to make the model firmly adhered to the printing platform. However, when it is necessary to demold after printing is completed, it is necessary to wait for the model to cool down before the adhesiveness between the model and the printing platform will decrease. Therefore, if you want to continue using the 3D printing device, you need to manually disassemble and replace the printing platform, resulting in a problem of consuming a lot of manpower during continuous production of products.

The other end of the damping rotating shaft is provided with bevel gears. A rack is arranged on the upper part of the base, and a limiting ring is fixed to the outer end of the upper part of the base.

[0008] Further, a pulley seat is arranged on the top of the limiting ring, and a return spring is connected to the top of the pulley seat. A pin is arranged inside the return spring, and the pin is fixedly connected with the pulley seat. A positioning hole is formed in the middle of the damping rotating shaft, and the end of the positioning hole is conical.

[0009] Further, the pin is slidably connected with the rotating table, and the bottom of the rotating table abuts against the top of the return spring.

[0010] Further, one end of the top plate is connected with a cleaning assembly, and the cleaning assembly includes a first toothed plate. One end of the top plate is provided with a first toothed plate, and a double gear is meshed with one side of the first toothed plate. A second toothed plate is meshed with one side of the upper part of the double gear, and an external toothed nut is meshed with the top of the second toothed plate. A screw rod is threadedly connected inside the external toothed nut, and a moving seat is arranged at one end of the screw rod. A smooth rod is arranged on one side of the moving seat.

[0011] Further, the double gear is rotatably connected with the base, and the guide frame is fixedly connected with the base.

The cross section of the connecting plate is L-shaped, and a second sliding column is slidably connected inside the connecting plate. A second spring is sleeved on the outside of the second sliding column, and one end of the second spring is connected with a scraper seat. The scraper seat is fixedly connected with the second sliding column. A waste box is arranged on one side of the base.

[0015] The replaceable product 3D printing platform provided by the present invention has the following beneficial effects: 1. The present invention realizes continuous printing operation by driving the automatic replacement of the carrier plate system through a dual-axis motor. At the same time, the self-locking structure of the worm reducer ensures the positioning accuracy of the platform. When unloading is required, the push rod can be driven to push the carrier plate made of spring steel to deform, so that the adhesion of the product is significantly reduced, thereby improving the separation effect of the product and the carrier plate. The operator only needs to pull lightly to remove the parts, avoiding the traditional disassembly process, so that the 3D printing operation can be carried out continuously.

[0016] 2. The present invention realizes that after unloading, the carrier plate can be automatically flipped to the top of the cleaning component through the linkage of the bevel gear and the limit ring, which is convenient for subsequent scraping and cleaning of the carrier plate. After cleaning, when the turntable continues to rotate, the carrier plate can be flipped and reset under the action of the bevel gear and the rack, without the need for additional control, which is more convenient. In addition, the linkage cooperation of the limit ring and the latch can be realized to automatically release the lock before flipping, and automatically lock it after reversing, without the need to add an additional control system, which is more convenient.

[0017] 3. The present invention drives the external tooth nut to rotate through the linkage mechanism of the top plate, the tooth plate and the double gear. Under the action of the base limit and the guide of the light rod, the screw drives the scraper seat to complete the automatic scraping and cleaning of the surface of the carrier plate, replacing the traditional manual scraping operation, significantly improving safety and working efficiency. The waste box and the scraper move synchronously to form a closed collection space, effectively preventing debris from splashing and realizing directional recovery. The structural design makes the cleaning action highly coordinated with the equipment operation and reduces additional energy consumption. At the same time, the scraper seat is equipped with a double-spring adaptive system. The first spring continuously applies vertical pressure to ensure that the scraper and the surface of the carrier plate maintain a dynamic and close fit. The second spring is set in an elastic buffer zone. When encountering stubborn attachments, impact inertia is generated through the energy storage and release mechanism, which can not only enhance the instantaneous cleaning force but also shake off the residue on the cutter head. The dual elastic structure enables the device to have constant pressure cleaning and self-maintenance characteristics at the same time, ensuring long-term stable operation.

[0026] Please refer to Figures 1 to 4 , the replaceable product 3D printing platform provided by the present invention includes a base 1 and a material discharging component 5. A dual-axis motor 2 is arranged inside the lower end of the base 1, and one end of the dual-axis motor 2 is connected to a worm reducer 3 through a one-way coupling. The output shaft of the worm reducer 3 is connected to a rotating table 4, and the material discharging component 5 is arranged at the other end of the dual-axis motor 2.

[0027] In some embodiments, the above-mentioned material discharging component 5 includes a bevel gear set 501. The other end of the dual-axis motor 2 is connected to the bevel gear set 501 through a one-way coupling. The top of the bevel gear set 501 is connected to a rotating disk 502 through a rotating shaft. One end of the top of the rotating disk 502 is fixed with a convex column 503, and a top plate 504 is slidably connected to the outside of the convex column 503. A guide frame 505 is slidably connected inside the top plate 504. A damping rotating shaft 506 is rotatably connected to the inside of the outer end of the rotating table 4, and a heating seat 507 is fixed to one end of the damping rotating shaft 506. A carrier plate 508 is arranged on one side of the heating seat 507, and side plates 509 are arranged on both sides of the carrier plate 508. One end of the side plate 509 is rotatably connected to a sliding plate 510, and slide bars 511 are slidably connected to the inside of both ends of the sliding plate 510. A compression spring 512 is sleeved on the outside of the slide bar 511, and the compression spring 512 is in contact with the heating seat 507. A support frame 513 is arranged at the bottom of the heating seat 507, and a top rod 514 is slidably connected to the inside of the support frame 513. The slide bar 511 is fixed to the heating seat 507, and the top rod 514 is slidably connected to the heating seat 507, and a radial flange is provided in the middle of the top rod 514.

[0028] It should be noted that by setting multiple carrier plates 508, after printing the product, the dual-axis motor 2 can be started, which drives the rotating table 4 to rotate through the one-way coupling and the worm reducer 3, so that the carrier plate 508 carrying the product can be removed from under the printer, and the carrier plate 508 can be automatically replaced, which is more convenient. At the same time, the one-way coupling at the other end of the dual-axis motor 2 is in an idling state, and there is no power transmission at this time. The self-locking characteristic of the worm reducer 3 can prevent the rotating table 4 from rotating due to external force, ensuring the positioning stability. When the product on the carrier plate 508 needs to be removed after cooling, the worm reducer 3 can be controlled to rotate in the reverse direction. At this time, under the action of the one-way coupling, there is no transmission between the dual-axis motor 2 and the worm reducer 3, and the dual-axis motor 2 can drive the bevel gear set 501 to rotate the rotating disk 502, so as to push the top plate 504 to slide outside the guide frame 505 through the convex column 503 and make a reciprocating motion; When the top plate 504 contacts the ejector rod 514, the ejector rod 514 can be pushed upward by squeezing the inclined surface of the top plate 504. At the same time, since the material of the carrier plate 508 is spring steel and has a certain deformation ability, when the ejector rod 514 squeezes the carrier plate 508, the carrier plate 508 can be deformed. At the same time, the side plate 509 can rotate, and the sliding plate 510 will slide toward the center on the sliding rod 511, so that the carrier plate 508 has a certain deformation space. Therefore, the bonding strength between the product and the carrier plate 508 can be reduced by the bending deformation of the carrier plate 508. And when the top plate 504 moves reciprocally, multiple groups of ejector rods 514 can be pushed in sequence, so as to change the position of the convex part of the carrier plate 508, and further improve the separation effect between the carrier plate 508 and the product.

[0029] Subsequent personnel only need to gently pull the product to remove it, without disassembling the carrier plate 508, thus improving the convenience during use. And when the top plate 504 is separated from the ejector rod 514, the ejector rod 514 will move downward under the action of gravity, the support frame 513 will limit the stroke of the ejector rod 514, and at the same time, the compression spring 512 will reset the sliding plate 510, and the carrier plate 508 will also be in a flat shape under its own elastic force and fit with the heating base 507, which is convenient for normal heating operation during the next printing.

[0030] Please refer to Figure 4 and Figure 5, the other end of the damping rotating shaft 506 is connected to a turning-over assembly 6, and the turning-over assembly 6 includes a bevel gear 601. The other end of the damping rotating shaft 506 is provided with the bevel gear 601. A rack 602 is arranged on the upper part of the base 1, and a limiting ring 603 is fixed to the outer end of the upper part of the base 1. A pulley seat 604 is arranged on the top of the limiting ring 603, and a return spring 605 is connected to the top of the pulley seat 604. A latch 606 is arranged inside the return spring 605, and the latch 606 is fixedly connected to the pulley seat 604. A positioning hole 607 is formed in the middle of the damping rotating shaft 506, and the end of the positioning hole 607 is conical. The latch 606 is slidably connected to the rotating table 4, and the bottom of the rotating table 4 abuts against the top of the return spring 605. One end of the top plate 504 is connected to a cleaning assembly 7, and the cleaning assembly 7 includes a first toothed plate 701.

[0031] When the rotating table 4 rotates, the bevel gear 601 can also be driven by the damping rotating shaft 506 to engage with the rack 602, so as to control the carrier plate 508 to turn over half a circle. After unloading, the carrier plate 508 can be automatically turned over above the cleaning assembly 7, which is convenient for subsequent scraping and cleaning of the carrier plate 508. After cleaning, when the rotating table 4 continues to rotate, the carrier plate 508 can be turned over and reset under the action of the bevel gear 601 and the rack 602 without additional control, which is more convenient. And before turning over, the pulley seat 604 can move to the concave part of the limiting ring 603, and the return spring 605 will push the pulley seat 604, so that the latch 606 is automatically separated from the positioning hole 607, releasing the rotation restriction of the damping rotating shaft 506. After turning over, the pulley seat 604 will be pushed to the convex part of the limiting ring 603, and can automatically insert into the positioning hole 607 to lock the rotation angle of the damping rotating shaft 506. And the end of the positioning hole 607 expands outwards, having a certain guiding and deviation-correcting function to improve the stability of the carrier plate 508 during the working process. Therefore, during the use process, the functions of automatic turning over and locking can be realized without adding an additional control system.

[0032] Please refer to Figure 3 , Figures 6 to 7, one end of the top plate 504 is provided with a first toothed plate 701, and a double gear 702 is engaged with one side of the first toothed plate 701. A second toothed plate 703 is engaged with the upper side of the double gear 702, and an external toothed nut 704 is engaged with the top of the second toothed plate 703. A screw rod 705 is threadedly connected inside the external toothed nut 704, and a moving seat 706 is arranged at one end of the screw rod 705. A smooth rod 707 is arranged on one side of the moving seat 706. The double gear 702 is rotatably connected to the base 1, and the guide frame 505 is fixedly connected to the base 1. The bottom convex part of the second toothed plate 703 is an isosceles trapezoid, and the second toothed plate 703 is slidably connected to the base 1. The external toothed nut 704 is rotatably connected to the base 1, and the smooth rod 707 is slidably connected to the base 1. A first sliding column 708 is slidably connected to the top of the moving seat 706. A first spring 709 is sleeved on the outside of the first sliding column 708, and the top of the first spring 709 is connected to a connecting plate 710, and the connecting plate 710 is fixedly connected to the first sliding column 708. The cross-section of the connecting plate 710 is L-shaped, and a second sliding column 711 is slidably connected inside the connecting plate 710. A second spring 712 is sleeved on the outside of the second sliding column 711, and one end of the second spring 712 is connected to a scraper seat 713, and the scraper seat 713 is fixedly connected to the second sliding column 711. A waste box 714 is arranged on one side of the base 1.

[0033] During the reciprocating movement of the top plate 504, the first toothed plate 701, the double gear 702, and the second toothed plate 703 can also drive the external toothed nut 704 to rotate. At this time, the base 1 will limit the position of the external toothed nut 704, and the rotation of the screw rod 705 will be restricted by the smooth rod 707 and the moving seat 706. Therefore, when the external toothed nut 704 rotates, the moving seat 706 can be driven by the screw rod 705 to move, driving the upper scraper seat 713 to scrape and clean the surface of the loading plate 508. There is no need for personnel to operate with a spatula, which is safer and more convenient. At the same time, the waste box 714 can be used to cover the outside, facilitating the collection of debris. And during the scraping and cleaning process, the first spring 709 will push the connecting plate 710 under the limit of the first sliding column 708, so that the scraper seat 713 can closely adhere to the surface of the loading plate 508, which is beneficial to improving the cleaning effect. When encountering attachments with relatively strong adhesion, the second spring 712 will contract under the action of resistance, so that the thrust of the scraper seat 713 gradually increases. When the thrust exceeds the adhesion threshold and the impurities fall off, the second spring 712 will push the scraper seat 713 to quickly reset, using inertia to shake off the residual debris, so that the scraper seat 713 has a certain self-cleaning ability, which is beneficial to maintaining the scraping and cleaning effect of the scraper seat 713.

[0034] In summary, when using the 3D printing platform of this product, after printing the product, first start the dual-axis motor 2, which drives the rotating table 4 to rotate through the one-way coupling and the worm reducer 3, so that the carrier plate 508 carrying the product can be moved away from under the printer, and the carrier plate 508 can be automatically replaced, facilitating continuous 3D printing on the next carrier plate 508; Next, when the product on the carrier plate 508 needs to be removed after cooling, the worm reducer 3 can be controlled to rotate in the reverse direction. At this time, under the action of the one-way coupling, there is no transmission between the dual-axis motor 2 and the worm reducer 3. The dual-axis motor 2 can drive the bevel gear set 501 to rotate the rotating disc 502, so that the convex column 503 pushes the top plate 504 to slide outside the guide frame 505 and make a reciprocating motion. And when the top plate 504 contacts the ejector rod 514, the ejector rod 514 can be squeezed by the inclined surface of the top plate 504 to move upward and squeeze the carrier plate 508, causing the carrier plate 508 to deform. At the same time, the side plate 509 can rotate, and the sliding plate 510 will slide towards the center on the slide bar 511, so that the carrier plate 508 has a certain deformation space. Therefore, the bonding strength between the product and the carrier plate 508 can be reduced through the bending deformation of the carrier plate 508. And when the top plate 504 moves reciprocally, multiple groups of ejector rods 514 can be pushed in sequence, thereby changing the position of the convex part of the carrier plate 508 and further improving the separation effect between the carrier plate 508 and the product. Subsequently, the operator only needs to gently pull the product to remove it; Then, when printing the next product, repeat the above operations. At this time, when the rotating table 4 rotates, the pulley seat 604 can move to the concave part of the limit ring 603, and the return spring 605 will push the pulley seat 604, causing the latch 606 to automatically separate from the positioning hole 607, releasing the rotation restriction of the damping rotating shaft 506. During this process, the rotating table 4 will also drive the bevel gear 601 to engage with the rack 602 through the damping rotating shaft 506, so as to be able to control the carrier plate 508 to flip half a circle, so that after unloading, the carrier plate 508 can be automatically flipped above the cleaning assembly 7. After flipping, the pulley seat 604 will be pushed to the convex part of the limit ring 603 again, and can automatically insert into the positioning hole 607 to lock the rotation angle of the damping rotating shaft 506. Then, when stripping the previous product, the top plate 504 will also drive the external tooth nut 704 to rotate through the first toothed plate 701, double gear 702, and second toothed plate 703. At this time, the base 1 will limit the position of the external tooth nut 704 and restrict the rotation of the screw 705 through the optical rod 707 and the moving seat 706. Therefore, when the external tooth nut 704 rotates, it can drive the moving seat 706 to move through the screw 705, driving the scraper seat 713 above to scrape and clean the surface of the carrier plate 508. And during the scraping and cleaning process, the first spring 709 will push the connecting plate 710 under the limit of the first sliding column 708, so that the scraper seat 713 can closely adhere to the surface of the carrier plate 508, which is beneficial to improving the cleaning effect. When encountering more firmly adhered attachments, the second spring 712 will contract under the action of resistance, so that the thrust of the scraper seat 713 gradually increases. When the thrust exceeds the adhesion threshold and impurities fall off, the second spring 712 pushes the scraper seat 713 to quickly reset, using inertia to shake off residual debris, so that the scraper seat 713 has a certain self-cleaning ability. At the same time, the waste box 714 can be used to mask the outside. Finally, after cleaning, when the rotating table 4 continues to rotate, similarly, the carrier plate 508 can be flipped and reset under the action of the bevel gear 601 and the rack 602.
