[0002] Cleaning 3D printed parts is an important part of the 3D printing post-processing workflow, especially for parts printed using photopolymerization technologies (such as SLA, DLP, etc.). The main purpose of cleaning is to remove uncured resin residue on the surface of the printed parts, as well as support structures or other impurities that may be attached to the printed parts. If these residues are not thoroughly cleaned, they will be cured during the subsequent curing process, thereby affecting the surface quality and performance of the printed parts.

[0003] Referring to the authorized announcement number "CN220242427U", a 3D printed part cleaning device is disclosed, which describes the technical problem of "the use of a cleaning box, a support plate, an electric push rod, a connecting component, a fixed plate, a cleaning basket, an adjusting component, a limiting plate and a limiting through groove to drive the limiting plate to slide, which can be adjusted according to the different heights of the printed objects, so as to facilitate the individual limiting of the printed objects. Then, by activating the electric push rod, the fixed plate and the cleaning basket are pushed up and down. The impact force of water pushes the cleaning basket and multiple printed objects to slide up and down, so as to achieve a cleaner surface cleaning of the printed objects".

[0004] In the process of implementing this patent, the applicant discovered the following technical problems:

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] As in the background art, the cleaning device in this patent achieves the cleaning effect by placing the printed parts inside the device and then immersing them. During this process, the cleaning water is in a static state, which makes it difficult to remove impurities from the surface of the printed parts, thus reducing the cleaning effect on the printed parts. At the same time, the device does not perform any drying or air-drying treatment on the cleaned printed parts, which reduces the cleaning efficiency of individual printed parts.

[0029] To solve this technical problem, this utility model provides a print cleaning device. By agitating the cleaning liquid when the print is placed inside the cleaning device, the cleaning state of the liquid inside the cleaning device can be changed, thereby enabling the cleaning liquid to flow and rinse the surface of the print, thus improving the cleaning effect on the surface of the print.

[0030] For details, please refer to Figures 1-2 A printing cleaning device specifically includes a fixed box 1. A first movable groove is provided at one end of the top of the fixed box 1, and a second movable groove is provided at the other end of the top of the fixed box 1. A cleaning component 2 is provided at the end of the top of the fixed box 1 near the first movable groove, and the bottom of the cleaning component 2 extends into the inner side of the first movable groove. A drying component 3 is provided inside the second movable groove.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please refer to Figures 1-2 A print cleaning device includes a fixed box 1, a first movable groove is provided at one end of the top of the fixed box 1, a second movable groove is provided at the other end of the top of the fixed box 1, a cleaning component 2 is provided at the end of the top of the fixed box 1 near the first movable groove, and the bottom of the cleaning component 2 extends into the inner side of the first movable groove, and a drying component 3 is provided in the inner side of the second movable groove.

[0034] When in use, place cleaning liquid inside the first active slot. The cleaning liquid includes, but is not limited to, liquids such as alcohol that can clean the surface of the printed parts.

[0035] Subsequently, the cleaning component 2 is used to move the printed parts up and down inside the first movable tank. The cleaning component 2 can agitate the liquid inside the first movable tank while the printed parts are moving up and down, thereby further improving the cleaning effect on the printed parts.

[0036] After cleaning the printed materials, they can be removed and, depending on the actual work needs, placed inside the drying component 3 if they need to be dried quickly. The drying component 3 can then be used to dry the printed materials, thereby improving the cleaning efficiency.

[0037] Example 2:

[0038] This embodiment 2 further discloses the specific structure of the cleaning component 2 based on the above embodiments. By cooperating with the structure in the above embodiments, the cleaning liquid is agitated when the printed parts are placed inside the cleaning device, thereby changing the cleaning state of the liquid inside the cleaning device. This allows the cleaning liquid to flow and rinse the surface of the printed parts, thereby improving the cleaning effect on the surface of the printed parts.

[0039] The print cleaning apparatus provided in Example 1 is further optimized, specifically, as follows: Figures 3-5 As shown, the cleaning assembly 2 includes a fixed vertical plate 4, a fixed horizontal plate 5, a first motor 6, a first screw 7, a first fixing rod 8, a strainer frame 9, a movable block 10, and a baffle 11. Fixed vertical plates 4 are fixedly connected to both sides of the top of the fixed box 1, and the fixed vertical plates 4 are located on both sides of the outer side of the top of the first movable groove. Fixed horizontal plates 5 are fixedly connected to the top of the two fixed vertical plates 4. A first motor 6 is fixedly connected to one side of the top of the fixed horizontal plate 5. The output end of the first motor 6 extends below the fixed horizontal plate 5 and is fixedly connected to the first screw 7. The bottom of the first screw 7 extends to the inner side of the first movable groove and connects to the bottom of the inner side of the first movable groove. The part is configured for rotational connection. A first fixed rod 8 is fixedly connected to the other side of the bottom of the fixed horizontal plate 5, and the bottom of the first fixed rod 8 extends to the inner side of the first movable groove and is fixedly connected to the bottom of the inner side of the first movable groove. A sluice frame 9 is provided inside the first movable groove. Movable blocks 10 are fixedly connected to both sides of the outer side of the sluice frame 9. One movable block 10 is threadedly connected to the first screw 7, and the other movable block 10 is slidably connected to the first fixed rod 8. One end of the sluice frame 9 is provided with an opening. The end of the sluice frame 9 with the opening is rotatably connected to a stop door 11 through a hinge, and the stop door 11 serves to block the opening.

[0040] The cleaning assembly 2 also includes a toothed plate 12, a first rotating rod 13, a transmission gear 14, a second rotating rod 15, a fan blade 16, and a bevel gear set 17. The toothed plate 12 is fixedly connected to both ends of one side of the drain frame 9. The first rotating rod 13 is rotatably connected to both ends of the inner side of the first movable groove near the toothed plate 12. The transmission gear 14 is fixedly connected to the side of the first rotating rod 13 near the toothed plate 12, and the transmission gear 14 is meshed with the toothed plate 12. The second rotating rod 15 is rotatably connected to the center position of both ends of the first movable groove. The fan blade 16 is fixedly connected to the end of the second rotating rod 15 near the drain frame 9. The bevel gear set 17 is provided on the outer side of the side of the first rotating rod 13 near the second rotating rod 15, and the first rotating rod 13 drives the second rotating rod 15 to rotate through the bevel gear set 17.

[0041] The cleaning assembly 2 also includes a second fixed rod 18, a first movable platform 19, and a limiting block 20. A third movable groove is provided at the bottom inner side of the drain frame 9. The second fixed rod 18 is fixedly connected to the inner side of the third movable groove. The first movable platform 19 is fitted with a gap at the bottom inner side of the drain frame 9. The limiting block 20 is fixedly connected to the bottom of the first movable platform 19 away from the stop door 11. The limiting block 20 extends to the inner side of the third movable groove and is fixedly connected to the second fixed rod 18.

[0042] Specifically, by flipping the stop 11 and removing the obstruction effect on the opening of the stencil 9, the first movable platform 19 can be pulled out from the inside of the stencil 9. At this time, the first movable platform 19 can drive the bottom limiting block 20 to move synchronously outside the second fixed rod 18. The second fixed rod 18 can connect the limiting block 20, and the limiting block 20 can limit the first movable platform 19, thereby preventing the first movable platform 19 from being pulled out from the inside of the stencil 9. Then, the printed part can be placed on top of the first movable platform 19, and then the first movable platform 19 can be pushed to move the printed part to the inside of the stencil 9, and the stop 11 can be closed.

[0043] Then, by turning on the first motor 6 and driving the first screw 7 to rotate, the first screw 7 is connected to one of the movable blocks 10 by a thread, which can drive the stencil 9 to move up and down inside the first movable slot. The stencil 9 can also drive the printed part to move inside the first movable slot. At the same time, the stability of the stencil 9 moving up and down can be improved by sliding the other movable block 10 to the first fixed rod 8.

[0044] As the squeegee 9 moves downward, it can drive the toothed plate 12 to move downward synchronously. Through the meshing connection between the toothed plate 12 and the transmission gear 14, when the toothed plate 12 moves downward, it can drive the first rotating rod 13 to rotate inside the first movable groove through the transmission gear 14. At the same time, through the connection of the bevel gear set 17, the first rotating rod 13 can drive the second rotating rod 15 to rotate synchronously. Thus, the second rotating rod 15 can drive the fan blade 16 to rotate and agitate the cleaning liquid inside the first movable groove, thereby breaking the calm effect of the liquid inside the first movable groove and generating water flow to wash the surface of the printed parts inside the squeegee 9.

[0045] At the same time, by controlling the first motor 6 to drive the first screw 7 to rotate intermittently in the forward and reverse directions, the squeegee 9 can be driven to move up and down inside the first movable groove, and the two fan blades 16 can be driven to rotate synchronously and alternately, thereby improving the cleaning effect on the printed parts inside the squeegee 9.

[0046] All the motors mentioned above are motors with power-off self-locking capability, such as servo motors.

[0047] Example 3:

[0048] This embodiment 3 further discloses the specific structure of the air-drying component 3 based on the above embodiments. By cooperating with the structure in the above embodiments, the air-drying component 3 can shorten the processing time of the printed parts and improve the cleaning efficiency of the printed parts by setting the ability to air-dry the cleaned printed parts.

[0049] The print cleaning apparatus provided in Embodiment 1 and Embodiment 2 has been further optimized, specifically, as follows: Figures 6-7 As shown, the air-drying assembly 3 includes a second motor 21, a second screw 22, a third fixing rod 23, and a second movable platform 24. A fourth movable slot is provided on both sides of the inner side of the second movable slot. The top of the fixed box 1 is fixedly connected to the second motor 21, which is located at the top of one of the fourth movable slots. The output end of the second motor 21 extends to the inner side of the corresponding fourth movable slot and is fixedly connected to the second screw 22. The bottom of the second screw 22 is rotatably connected to the bottom of the inner side of the fourth movable slot. A third fixing rod 23 is fixedly connected to the inner side of the other fourth movable slot. A second movable platform 24 is provided inside the second movable slot. One side of the second movable platform 24 extends to the inner side of one of the fourth movable slots and is threadedly connected to the second screw 22. The other side of the second movable platform 24 extends to the inner side of the other fourth movable slot and is slidably connected to the third fixing rod 23.

[0050] The air drying assembly 3 also includes a blower module 25 and a ventilation duct 26. A fifth movable slot is provided on the inner side of the fixed box 1 near the second movable slot. The fifth movable slot is located below the second movable slot. The blower module 25 is fixedly connected to the inner side of the fifth movable slot. Multiple ventilation ducts 26 are fixedly connected to both ends of the blower module 25. The blower module 25 is connected to the inner side of the second movable slot through the multiple ventilation ducts 26.

[0051] Specifically, when the printed parts need to be dried, the printed parts can be placed on top of the second movable platform 24, then the second motor 21 is turned on and the second screw 22 is driven to rotate, thereby driving the second movable platform 24, which is threadedly connected to the second screw 22, to move up and down inside the second movable groove. At the same time, the stability of the second movable platform 24 moving up and down in the second movable groove can be improved by setting the third fixing rod 23.

[0052] The blower module 25 can be a CCR-50 blower or a similar model. When the blower module 25 is turned on, air is blown into the inside of the second movable slot through the ventilation duct 26, thereby drying the printed parts on the top of the second movable platform 24. In addition, the second movable platform 24 moves the printed parts, which further improves the drying effect of the printed parts.

[0053] All the motors mentioned above are motors with power-off self-locking capability, such as servo motors.
