Description

Technical Field

[0001] This utility model relates to the field of printer technology, and more particularly to 3D resin printers. Background Technology

[0002] 3D printing is a revolutionary technology that builds objects by stacking materials layer by layer based on three-dimensional model data. Compared with traditional subtractive manufacturing, it has significant advantages such as manufacturing complex structures, personalized customization, high material utilization, and short production cycle.

[0003] Photopolymer 3D printers use resin materials, which are cured by irradiating liquid resin with light of a specific wavelength, resulting in a smooth surface on the printed product. Resin-based 3D printers have a resin tank at the bottom of the cavity, and a printing plate is placed above the resin tank. As the printing plate rises, the printing layers are stacked. However, existing printing plates are usually fixed to the moving mechanism with bolts. When the printing plate needs to be replaced, cleaned, or maintained, disassembly requires other tools, making disassembly inconvenient. Therefore, we propose a 3D resin printer to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a 3D resin printer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A 3D resin printer includes a printer body with a resin storage box inside. A guide frame is fixedly installed at the middle of the inner side of the printer body. A sliding seat is placed on the side of the guide frame. A servo motor is fixedly installed at the top of the guide frame, and a rotating lead screw is fixedly installed at the bottom of the servo motor. A mounting seat is fixedly installed at the end of the sliding seat, and a printing plate is placed at the bottom of the mounting seat. Mounting plates are fixedly installed on both sides of the top of the printing plate, and mounting slots are formed at the ends of the mounting plates. Mounting clips are fixedly installed on both sides of the mounting seat, and the mounting clips and mounting slots are mutually compatible. It allows the printing plate to be disassembled horizontally without the need for auxiliary tools, thus improving the efficiency of disassembly, cleaning, and maintenance.

[0006] Preferably, the mounting plate has a mounting hole groove at its end, and a connecting rod is fixedly installed at the middle position of the end of the mounting hole groove, with a limit block sleeved on the outside of the connecting rod; After the mounting slotted sleeve is attached to the outside of the mounting plate, the limiting block moves and presses against the side wall of the mounting plate, thereby increasing the stability of the printing plate after installation.

[0007] Preferably, a circular groove is formed at the end of the mounting slot, and the limiting block is adapted to the circular groove at the end of the mounting slot; The limiting block can be moved and embedded into the circular groove at the end of the mounting slot, which prevents the mounting slot from detaching from the mounting plate, thus improving the stability of the printing plate after installation.

[0008] Preferably, the connecting rod is hexagonal, and the limiting block is adapted to the connecting rod; This can improve the stability of the limit block's movement and prevent the limit block from rotating.

[0009] Preferably, a movable block is placed inside the connecting rod, and connecting blocks are fixedly installed on all four sides of the outer wall of the movable block. A sliding groove is opened on all four sides of the outer wall of the connecting rod, and the connecting block passes through the sliding groove and is fixedly connected to the inner wall of the limiting block. This can further improve the stability of the limit block's movement, thus enabling the limit block to perform its limiting function better.

[0010] Preferably, a pull rod is inserted into the end of the connecting rod, the pull rod has a T-shaped cross-section, and the end of the pull rod is fixedly connected to the moving block; Personnel can pull the lever from the outside, causing the lever to move the moving block and the limiting block, thus facilitating the disassembly of the printing plate by removing the limiting block from the circular groove at the mounting end.

[0011] Preferably, a support spring is sleeved on the outside of the pull rod, one end of the support spring is fixedly connected to the inner wall of the connecting rod, and the other end of the support spring is fixedly connected to the moving block; The support spring can support the moving block, thereby allowing the limiting block to be better positioned inside the circular groove at the mounting slot end.

[0012] Preferably, the end of the limiting block is inclined, and the inclined surface of the limiting block is adapted to the side of the mounting plate; During installation, the mounting plate is squeezed out from the inclined surface of the limiting block, causing the limiting block to move along the inclined surface. It then returns to its original position via the support spring, making the installation of the printing plate more convenient.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model allows the limiting block to move by pulling the pulling rod, thereby disengaging the limiting block from the circular groove at the end of the mounting slot. This allows the printing plate to slide directly away from the mounting base, completing the disassembly of the printing plate without the need for other tools, making disassembly more convenient and improving the efficiency of printing plate disassembly.

[0014] 2. This utility model allows the end of the mounting plate to press against the limiting block during installation after the printing plate has been cleaned and maintained. This causes the limiting block to move along the inclined surface. Subsequently, the mounting slot is fitted onto the outside of the mounting plate, and the support spring drives the limiting block to return to its original position, so that the limiting block is embedded in the circular groove at the end of the mounting slot, thereby completing the limiting installation of the printing plate and making the installation of the printing plate more convenient.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-6The 3D resin printer shown has a resin placement box 2 inside the cavity of the printer body 1, where liquid resin can be placed. A guide frame 3 is fixedly installed at the middle of the side of the inside of the printer body 1. A sliding seat 4 is placed on the side of the guide frame 3, and a groove is formed on the surface of the guide frame 3, so that a protrusion at the end of the sliding seat 4 extends into the groove. A servo motor 5 is fixedly installed at the top of the guide frame 3, and a rotating screw 6 is fixedly installed at the bottom of the servo motor 5. The rotating screw 6 extends into the groove in the middle of the inside of the guide frame 3, so that the sliding seat 4 is threadedly connected to the rotating screw 6. The rotation of the rotating screw 6 can drive the sliding seat 4 to rise and fall. A mounting base 7 is fixedly installed at the end of the sliding seat 4, and a printing plate 8 is placed at the bottom of the mounting base 7. Mounting plates 9 are fixedly installed on both sides of the top of the printing plate 8, and the area of ​​the printing plate 8 is adapted to the area of ​​the resin placement box 2.

[0019] For a detailed description of the mounting plate 9 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4 A mounting slot 10 is provided at the end of the mounting plate 9, and a circular groove is provided at the end of the mounting slot 10. Mounting plates 11 are fixedly mounted on both sides of the mounting base 7, so that the mounting plates 11 and the mounting slot 10 are mutually adapted. A mounting hole 12 is provided at the end of the mounting plate 11, and a connecting rod 13 is fixedly mounted at the middle position of the end of the mounting hole 12. The connecting rod 13 is hexagonal, and a limiting block 14 is sleeved on the outside of the connecting rod 13, so that the limiting block 14 and the circular groove at the end of the mounting slot 10 are mutually adapted. A movable block 15 is placed inside the connecting rod 13. Connecting blocks 16 are fixedly installed on all four sides of the outer wall of the connecting rod 13, and sliding slots 17 are opened on all four sides of the outer wall of the connecting rod 13, so that the connecting blocks 16 pass through the sliding slots 17 and are fixedly connected to the inner wall of the limiting block 14. Finally, a pulling rod 18 is inserted into the end of the connecting rod 13. The cross-section of the pulling rod 18 is T-shaped, so that the end of the pulling rod 18 is fixedly connected to the moving block 15. A support spring 19 is sleeved on the outside of the pulling rod 18, so that one end of the support spring 19 is fixedly connected to the inner wall of the connecting rod 13, and the other end of the support spring 19 is fixedly connected to the moving block 15. Meanwhile, the side of the limiting block 14 is inclined.

[0020] Working principle: When using this utility model, by pulling the pulling rod 18, the pulling rod 18 drives the limiting block 14 to move through the moving block 15 and the connecting block 16, so that the limiting block 14 disengages from the groove at the end of the mounting slot 10. At this time, the printing plate 8 can move laterally directly, so that the mounting slot 10 on the mounting plate 9 disengages from the mounting clip 11, thus completing the disassembly, cleaning and maintenance of the printing plate 8.

[0021] After maintenance and cleaning, the printing plate 8 can be placed under the mounting base 7 along with the mounting plate 9, so that the mounting slot 10 corresponds to the mounting plate 11, and the mounting slot 10 fits onto the outside of the mounting plate 11. The end of the mounting plate 9 contacts the inclined surface of the limiting block 14, causing the limiting block 14 to move along the inclined surface. Then, the moving block 15 is driven by the support spring 19 to return to its original position, so that the limiting block 14 is locked inside the circular groove at the end of the mounting slot 10 to complete the limiting, making the installation of the printing plate 8 more convenient.
