Description

Technical Field

[0001] This utility model relates to the field of photopolymer 3D printing technology, and in particular to a resin recovery device for photopolymer 3D printing equipment. Background Technology

[0002] Photopolymer 3D printers use resin as the printing material. During printing, the molding platform is pressed into the resin tank, and the molding platform solidifies the resin to print the designed model. After printing, a large amount of resin material will stick to the molding platform. Since resin material is relatively expensive, it is necessary to recycle the resin stuck to the molding platform in order to avoid resource waste.

[0003] Chinese Patent CN220661744U discloses a resin recovery device for a photopolymerization 3D printing equipment. The device includes a worktable with a frame fixedly connected to its top. The frame has a sliding rail for a power-operated slide table inside, and a mounting frame is fixedly connected to its outer wall. A cleaning mechanism is installed both inside and outside the mounting frame. This invention, by setting up a cleaning mechanism and a collection mechanism, allows a moving scraper to remove resin adhering to the bottom of the molding platform. The residual resin scraped off by the scraper falls into a collection box. The collection box, rotating 90 degrees counterclockwise, pours the received residual resin into a collection container. This allows for unified recycling of the residual resin received by the collection container, achieving the effect of simultaneously scraping and collecting resin adhering to the molding platform, avoiding waste of resin resources, and reducing the workload of the operator.

[0004] Existing photopolymer 3D printing equipment uses a collection box to collect the recycled resin. However, the collection box is open, allowing dust from the working environment to enter the box, and oxygen and moisture from the air to come into contact with the recycled resin. The collection box does not have a light-shielding function, which causes the resin recycling to trigger a curing reaction, resulting in the resin becoming thicker, clumping, or even completely curing, thus affecting the quality of the recycled resin.

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] Example 1

[0031] like Figure 1 - Figure 5 As shown, this utility model proposes a resin recycling device for a photopolymerization 3D printing equipment, comprising: a worktable 1, a frame 2, a recycling component, a central assembly, and a multifunctional assembly; the frame 2 is connected to the worktable 1; the recycling component is connected to the frame 2; the central assembly is connected to the recycling component; the central assembly includes a collection box 4, a splicing frame 401, a support plate 402, a gear b403, a rotating shaft 404, a motor b405, a base plate 406, a moving groove 407, and two sets of sealing components; the collection box 4 is connected to the recycling component via the splicing frame 401, and the splicing frame 401... 1. A support plate 402 is connected to one side, which in turn connects to a base plate 406. The base plate 406 connects to a motor b405, which in turn connects to a rotating shaft 404. A gear b403 is connected to the outer periphery of the rotating shaft 404. The base plate 406 connects to a moving groove 407. Two sets of seals are connected to both sides of the inner wall of the collection box 4. A multi-functional component is connected to the collection box 4. The multi-functional component includes a moving cover 5, a fixed plate 501, and a rack b502. The moving cover 5 is connected to the fixed plate 501, which is connected to the rack b502 and has a guide block connected below it. The collection box 4 and the moving cover 5 are made of opaque material to avoid the resin recycling process being triggered by light sources in the working environment, which could lead to resin thickening, clumping, or even complete curing. This improves the performance of the components of the resin recycling device.

[0032] To further explain, the guide block is connected within the moving groove 407, and the tooth groove of the rack b502 meshes with the gear b403. Openings are provided on both sides of the collection box 4, connecting to the moving cover 5. The moving cover 5 is connected to two sets of seals on both sides. The fixed plate 501 moves via the rack b502 and gear b403, causing the guide block to move along the inner wall of the moving groove 407 during movement, thus facilitating increased stability and improving the connection between the moving cover 5 and the collection box 4.

[0033] To further explain, the two sets of sealing components include a sealing strip 408 and a sealing plate 409, respectively. The sealing strip 408 and sealing plate 409 are connected to the inner wall of the collection tank 4, with the sealing strip 408 connected above the opening and the sealing plate 409 connected below the opening. The sealing strip 408 and sealing plate 409 have the same size and thickness. The sealing strip 408 is connected to the upper surface of the movable cover 5, and the sealing plate 409 is connected to the lower surface of the movable cover 5. Through the connection of the sealing strip 408 and sealing plate 409, when the movable cover 5 is moved to the collection tank 4 and closed, the sealing components connect with the upper and lower surfaces of the movable cover 5, achieving a sealing effect and preventing dust or oxygen and moisture in the air from contacting the recycled resin, thus conveniently improving the quality of resin recycling.

[0034] Example 2

[0035] like Figure 1 and Figure 2As shown, this utility model proposes a resin recycling device for a photopolymerization 3D printing equipment. Based on the above embodiments, this embodiment also details the specific components of the frame 2 and the recycling part, as well as their arrangement.

[0036] Further explanation: The recycling components include a mounting frame 3, a motor a301, a screw 302, a moving block 303, an L-shaped rod a304, a scraper 305, a connecting plate 306, an L-shaped rod b307, a collection box 308, a gear a309, and a rack a310. The motor a301 is connected to one side of the mounting frame 3. The motor a301 is connected to the screw 302. The screw 302 is threadedly engaged with the moving block 303. The moving block 303 is connected to the L-shaped rod a304. The L-shaped rod a304 is connected to the scraper 305 and is connected to the connecting plate 306. The connecting plate 306 is connected to the L-shaped rod b307. One end of the L-shaped rod b307 is connected to the collection box 308, and the other end is externally connected to the gear a309. The gear a309 and the rack a310 are meshed together. Mounting bracket 3 is connected to one side of frame 2. Mounting bracket 3 has two strip slots. The upper strip slot is connected to screw 302, and the lower strip slot is axially slidably connected to one end of L-shaped rod b307. Guide rods are slidably connected to the upper and lower sides of moving block 303. The guide rods are connected in the extension slot, and the extension slot extends onto the upper strip slot. The length of rack a310 is sufficient for gear a309 to rotate along the track. The rotation causes L-shaped rod b307 to drive collection box 308 to rotate downward 90 degrees, so that the recycled resin is concentrated in collection box 4. After the photopolymerization 3D printing equipment is used, by starting motor a301, motor a301 drives screw 302 to rotate. Screw 302 slides the guide rod and moves moving block 303 downward toward the molding platform 7. The moving block 303 drives the L-shaped rod a304, which in turn drives the scraper 305 to move along the bottom surface of the molding platform 7, scraping the resin off the bottom of the molding platform 7. The L-shaped rod a304 drives the L-shaped rod b307 to move via the connecting plate 306. The L-shaped rod b307 drives the collection box 308, which then collects the scraped resin. After the resin is scraped and collected, the motor a301 is controlled to move the screw 302 in the opposite direction. The L-shaped rod b307 drives the gear a309 to move and connect with the rack a310, causing the gear a309 to rotate along the rack a310 and drive the L-shaped rod b307 to rotate. The L-shaped rod b307 drives the collection box 308, which rotates to automatically drop the collected resin into the collection tank 4.

[0037] To further explain, frame 2 is connected to a slide rail, which in turn connects to an electric slide table 6. The electric slide table 6 is connected to a molding platform 7. A resin tank 8 is connected to the worktable 1, and the resin tank 8 corresponds to the molding platform 7. The recyclable part is movably connected to the lower surface of the molding platform 7, allowing the resin adhering to the bottom of the molding platform 7 to be scraped off and recycled.

[0038] The working principle of this utility model is as follows: During the process of the resin recovered by the collection box 308 moving in the opposite direction towards the collection tank 4, the motor b405 is started. The motor b405 drives the rotating shaft 404 to rotate, which in turn drives the gear b403. The gear b403 drives the rack b502, causing the fixed plate 501 to move. The fixed plate 501 then drives the movable cover 5 to move towards the gear b403, opening the collection tank 4. After opening, the collection box 308 rotates, and the resin recovered by the collection box 308 falls into the collection tank 4 for collection and processing. After the recovered resin is collected in the collection tank 4, it is then... The collection box 308 moves through the recycling components to recycle resin from the photopolymer 3D printing equipment. During the resin recycling process, the movable cover 5, through the cooperation of components such as the fixed plate 501, rack b502, and gear b403, moves in the opposite direction, passing through the opening and connecting to the opening of the collection box 4. This closes the opening of the collection box 4, preventing dust from entering the collection box and affecting resin recycling. It also prevents oxygen and moisture in the air from contacting the recycled resin, slowing down the resin oxidation and moisture absorption process, improving the quality of resin recycling, and enhancing the use of the resin recycling device in the photopolymer 3D printing equipment.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
