Description

Technical Field

[0001] This utility model relates to the field of ceramic 3D printing technology, specifically to a slurry box lifting mechanism for a desktop ceramic 3D printer. Background Technology

[0002] The slurry hopper lifting mechanism of a desktop ceramic 3D printer typically employs an electric or mechanical drive system to ensure precise raising and lowering of the slurry hopper during printing. This mechanism is generally controlled by a stepper motor or electric cylinder. The precision of the lifting mechanism design is crucial for the printing process, ensuring uniform distribution of the ceramic slurry and printing accuracy. Simultaneously, the stability of the mechanism effectively prevents slurry fluctuations or errors from affecting the molding quality during printing.

[0003] The ink cartridge lifting mechanism of the desktop small ceramic 3D printer disclosed in Chinese Patent Publication No. CN215589437U has high precision in controlling the lifting of the ink cartridge with screw drive. Two drive units are set on both sides of the top plate to improve the balance and stability of the ink cartridge during lifting, avoid contact between the drive units and the ink, and extend the service life of the drive units. However, the ink cartridge lifting mechanism has low flexibility in use. After long-term use, the ink cartridge may be deformed or damaged due to pressure or external forces, which will affect the overall stability of the ink cartridge and lifting mechanism and the subsequent printing effect. Utility Model Content

[0004] The purpose of this invention is to provide a slurry box lifting mechanism for a desktop ceramic 3D printer, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slurry box lifting mechanism for a desktop ceramic 3D printer, including a worktable, a base located at the middle of the top of the worktable, a main box body located at the top of the base, lifting components located on both sides of the top of the worktable, a connecting mechanism located on one side of the lifting components, a material layer located inside the main box body, and a mounting bracket fixedly connected to the top of the worktable.

[0006] Preferably, bolts threaded to the base are installed at both ends of the outer side of the workbench, a baffle is fixedly connected to the top of the base, a slot is provided inside the top of the base, and an insertion frame that engages with the slot is fixedly connected to the bottom of the main box.

[0007] Preferably, the lifting assembly includes a slide rod fixedly connected to the middle position of one side of the top of the worktable, a slider slidably connected to the outside of the slide rod, a servo motor installed on one side inside the top of the worktable, a threaded rod installed on the output shaft end of the servo motor, and a threaded block threadedly connected to the outside of the threaded rod.

[0008] Preferably, the connecting mechanism includes a telescopic rod that is fixedly connected to one side of the slider and the threaded block, a slot is provided on one side of the top end of the telescopic rod, and a toggle block is fixedly connected to one side of the top end of the telescopic rod.

[0009] Preferably, the main box body has connecting grooves on both sides of its exterior that engage with telescopic rods, and pull rods are slidably connected to both sides of the top of the main box body. A movable block is fixedly connected to the bottom of the pull rod, a spring is fixedly connected to the top of the movable block, and a locking block that engages with a slot is fixedly connected to the bottom of the movable block.

[0010] Preferably, the material layer includes an elastic layer disposed in the middle of the main box body, an outer protective layer disposed outside the elastic layer, and an adhesive layer disposed inside the elastic layer.

[0011] Preferably, the elastic layer is made of silicone, the outer protective layer is made of polycarbonate, and the bonding layer is made of polytetrafluoroethylene coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The ink cartridge lifting mechanism of this desktop ceramic 3D printer can be connected to the main cartridge by a connecting mechanism on one side of the lifting component. When the telescopic rod on the connecting mechanism is inserted into the connecting slot on the main cartridge, and the locking block inside the main cartridge engages with the slot on the telescopic rod, the installation of the lifting component and the main cartridge can be completed. By pulling the pull rod on the main cartridge, the pull rod can drive the locking block to be pulled out from the slot on the telescopic rod through the movable block. At this time, the main cartridge can be quickly disassembled and replaced. The base can be removed from the worktable and replaced by bolts, thereby improving the functionality of the lifting mechanism while ensuring the stability of subsequent ceramic 3D printing.

[0014] 2. The slurry cartridge lifting mechanism of this desktop ceramic 3D printer features an elastic layer, an outer protective layer, and an adhesive layer within the main cartridge. The elastic layer provides the main cartridge with a certain degree of elasticity, helping to cope with temperature and pressure changes. The outer protective layer provides excellent mechanical strength, allowing it to withstand external pressure, impact, and repeated use. Simultaneously, the adhesive layer within the elastic layer has an extremely low coefficient of friction, significantly reducing friction between the ceramic layer and the interior of the main cartridge, ensuring smoother demolding. This mechanism maintains the strength of the slurry cartridge while improving the demolding performance of ceramic items, effectively extending the service life of both the lifting mechanism and the slurry cartridge.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides two technical solutions:

[0022] Example 1: A slurry cassette lifting mechanism for a desktop ceramic 3D printer includes a worktable 1, a base 2 located at the center of the top of the worktable 1, a main cassette 3 located at the top of the base 2, lifting components 4 located on both sides of the top of the worktable 1, a connecting mechanism 5 located on one side of the lifting components 4, a material layer 7 located inside the main cassette 3, and a mounting bracket 8 fixedly connected to the top of the worktable 1, through which the ceramic 3D printer equipment can be installed.

[0023] Bolts 201, which are threadedly connected to the base 2, are installed at both ends of the outer side of the workbench 1. A baffle 202 is fixedly connected to the top of the base 2. A slot 203 is provided inside the top of the base 2. An insertion frame 301 that engages with the slot 203 is fixedly connected to the bottom of the main box 3. The baffle 202 can be used for auxiliary positioning of the main box 3. The baffle 202 is made of transparent glass, which helps the light source to shine through the bottom to the paste during photopolymerization printing, ensuring that the ceramic paste can be fully cured and ensuring the molding quality of each layer. At the same time, rubber pads are provided at the connection between the insertion frame 301 and the slot 203 to increase the sealing of the connection between the base 2 and the main box 3.

[0024] The lifting assembly 4 includes a slide rod 101 fixedly connected to the middle position of one side of the top of the worktable 1. A slider 102 is slidably connected to the outside of the slide rod 101. A servo motor 401 is installed on one side inside the top of the worktable 1. A threaded rod 402 is installed on the output shaft end of the servo motor 401. A threaded block 403 is threadedly connected to the outside of the threaded rod 402. When the servo motor 401 is started, it can drive the threaded rod 402 to rotate. At this time, the threaded block 403 on the threaded rod 402 can drive the main box 3 to move up and down through the connecting mechanism 5. At the same time, the main box 3 can drive the slider 102 to slide on the slide rod 101 through another set of connecting mechanisms 5. At this time, the slide rod 101 and the slider 102 can play a role in stabilizing and limiting the main box 3.

[0025] The connecting mechanism 5 includes a telescopic rod 501 that is fixedly connected to the slider 102 and the threaded block 403 on one side. A slot 502 is provided on one side of the top end of the telescopic rod 501. A toggle block 503 is fixedly connected to one side of the top end of the telescopic rod 501. The toggle block 503 can pull one side of the telescopic rod 501 to move. When one side of the telescopic rod 501 is inserted into the connecting slot 302 on the main box 3, and at the same time the locking block 603 in the main box 3 is engaged in the slot 502 on the telescopic rod 501, the connection between the main box 3 and the connecting mechanism 5 can be completed.

[0026] The main box 3 has connecting slots 302 on both sides of its exterior that engage with the telescopic rod 501. Pull rods 6 are slidably connected to both sides of the top of the main box 3. A movable block 601 is fixedly connected to the bottom of the pull rod 6. A spring 602 is fixedly connected to the top of the movable block 601. A locking block 603 that engages with the slot 502 is fixedly connected to the bottom of the movable block 601. Pulling the pull rod 6 will cause the pull rod 6 to compress the spring 602 through the movable block 601. At the same time, the movable block 601 can drive the locking block 603 to lift upward. By releasing the pull rod 6, the locking block 603 can be reset by the reaction force of the spring 602 being compressed through the movable block 601.

[0027] Example 2 differs from Example 1 mainly in that:

[0028] A slurry box lifting mechanism for a desktop ceramic 3D printer includes an elastic layer 701 disposed in the middle of the main box body 3 in the material layer 7, an outer protective layer 702 disposed outside the elastic layer 701, and an adhesive layer 703 disposed inside the elastic layer 701.

[0029] The elastic layer 701 is made of silicone, which gives the slurry box a certain degree of elasticity to help cope with temperature and pressure changes. At the same time, silicone has good high temperature resistance, making it suitable for use in high temperature curing or heating processes.

[0030] The outer protective layer 702 is made of polycarbonate, which has good mechanical strength and can withstand external pressure, impact and repeated use. At the same time, it exhibits good corrosion resistance in common ceramic slurry environments.

[0031] The bonding layer 703 is made of polytetrafluoroethylene coating, which has an extremely low coefficient of friction. This can greatly reduce the friction between the ceramic layer and the slurry box, ensuring smoother demolding. It also has strong corrosion resistance and can adapt to corrosive components that may be present in the ceramic slurry. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] In this embodiment, the slurry is poured into the interior of the main box 3, and the ceramic 3D printer mounted on the mounting bracket 8 can print the slurry inside the main box 3. After a single layer is printed, the servo motor 401 is started to drive the threaded rod 402 to rotate. The threaded block 403 on the threaded rod 402 can lift the main box 3 through the connecting mechanism 5. At this time, the thickness of the top layer of ceramic slurry can be precisely adjusted by lifting the main box 3, and the next layer can be printed by the ceramic 3D printer. At the same time, as the main box 3 is lifted, the ceramic material printed at the bottom of the main box 3 can protrude from the bottom of the main box 3. At this time, the external light source shines on the slurry layer through the enclosure 202 to solidify the ceramic slurry, helping the printed object to be formed layer by layer, and completing the ceramic object printing work.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
