Description

Technical Field

[0001] This utility model relates to the technical field of ceramic 3D printers, and in particular to a 3D ceramic printer scraper that can be adjusted at multiple angles. Background Technology

[0002] A 3D ceramic printer is an instrument that can directly manufacture ceramic products with complex structures. During the printing process, a scraper is used to spread the ceramic slurry. A scraper that cannot be adjusted in height and angle is difficult to handle high-viscosity slurry and is highly dependent on the printing platform. If the platform is slightly tilted, the slurry cannot be spread evenly. Different ceramic materials also have different requirements for the angle of the scraper. Therefore, a 3D ceramic printer scraper that can be adjusted at multiple angles is needed.

[0003] However, most existing 3D ceramic printer scrapers are usually fixed at a fixed angle when spreading the slurry, and cannot be adjusted to multiple angles. The inability to adjust the scraper to multiple angles will significantly limit the stability and shape of the printed ceramics.

[0004] To address the aforementioned issues, a search revealed CN221793139U, a publication titled "A Multi-Angle Adjustable Scraper for a 3D Ceramic Printer." This publication describes a scraper holder comprising a main body, a clamping block, and a lifting assembly mounting base. The multi-angle adjustment assembly includes a lifting assembly, a vertical angle adjustment unit, and a horizontal angle adjustment unit. The lifting assembly includes an adjusting screw, an adjusting knob, and a universal joint. The adjusting screw, in conjunction with the adjusting knob, adjusts the lifting of the scraper unit. The vertical angle adjustment unit includes a first adjusting bolt and a second adjusting bolt. The horizontal angle adjustment unit includes a third adjusting bolt and a fourth adjusting bolt. The extension directions of the first and second adjusting bolts are perpendicular to the extension directions of the third and fourth adjusting bolts, allowing the vertical and horizontal angle adjustment units to adjust the scraper unit from different angles. While the vertical and horizontal angle adjustment units provide a limited range of angle adjustment, they still limit the scraper's tilt angle.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

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. 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.

[0018] Please see Figure 1-6 This utility model provides a technical solution: a 3D ceramic printer scraper that can be adjusted at multiple angles, including a slurry tank 1, a first square groove 2 slidably connected to the side surface of the slurry tank 1, a motor 3 fixedly installed at the top of the first square groove 2, a threaded rod 4 fixedly connected to the output end of the motor 3 through the top of the first square groove 2, an internal threaded block 5 threadedly connected to the outer ring of the threaded rod 4, a support seat 6 rotatably connected to the bottom of the threaded rod 4, a first fixing block 7 fixedly installed on one side of the internal threaded block 5, a connecting rod 8 fixedly installed at the center of the first fixing block 7, a small motor 9 fixedly installed at one end of the connecting rod 8, a fixing plate 10 fixedly installed on the lower surface of the connecting rod 8, a scraper 11 fixedly installed at the lower opening of the fixing plate 10, a second square groove 12 slidably connected to the other side surface of the slurry tank 1, a fixing rod 13 welded inside the second square groove 12, a second fixing block 14 sleeved on the outer ring of the fixing rod 13, and a limit ring 15 fixedly installed at the other end of the connecting rod 8.

[0019] Furthermore, the small motor 9 is supported by an L-shaped connecting block. One end of the L-shaped connecting block is welded to the first fixing block 7, and the other end is fixed to the small motor 9 by bolts. Through the arrangement of the small motor 9 and the first fixing block 7, stability is maintained when the small motor 9 is driven to rotate.

[0020] Furthermore, the fixing plate 10 is H-shaped, and the connecting rod 8 and the scraper 11 are fixed to the upper and lower openings of the fixing plate 10 by bolts respectively. With the setting of the fixing plate 10, the connecting rod 8 and the scraper 11, the scraper 11 can be easily replaced by loosening and removing the bolts. The corresponding scraper 11 is selected according to different ceramic materials.

[0021] Furthermore, the inner ring of the second fixing block 14 is provided with a limiting groove 17 for fitting the limiting ring 15. The limiting ring 15 and the limiting groove 17 fit together, which can provide stability during rotation, so that the scraper 11 does not shift, avoiding problems with the stability and precision of the final ceramic product due to deviation.

[0022] Furthermore, an indicator needle 19 is designed at the end of the connecting rod 8 away from the small motor 9. The side surface of the second fixing block 14 corresponding to the indicator needle 19 is engraved with a degree mark 18. The indicator needle 19 is engraved with a degree mark 18 on the second fixing block 14. With the setting of the indicator needle 19 and the degree mark 18, the indicator needle 19 rotates with the connecting rod 8, and the degree mark 18 engraved on the second fixing block 14 will not rotate, so the specific degree of rotation can be clearly and intuitively seen.

[0023] Furthermore, the tilt sensor 16 is mounted on the side surface of the fixed plate 10. Through the arrangement of the tilt sensor 16 and the fixed plate 10, the tilt sensor 16, model GY25, can detect the tilt angle in the three directions of X-axis, Y-axis and Z-axis, and provide real-time feedback on the current tilt angle according to its matching simulation software.

[0024] Furthermore, the dimensions of the first square groove 2 and the second square groove 12 are matched. With the arrangement of the first square groove 2, the slurry trough 1, the second square groove 12 and the slurry trough 1, when the linear motor drives the horizontal movement, the bottom slides in the groove to maintain the stability of the movement.

[0025] Working principle: First, the slurry is placed into the slurry tank 1. Then, the motor 3 drives the threaded rod 4 to rotate. The threaded rod 4 drives the internal threaded block 5 to move up and down reciprocally. The internal threaded block 5 pulls the first fixed block 7 to adjust the height. Then, when the scraper 11 is adjusted, the small motor 9 drives the connecting rod 8 to rotate. Then, the limiting ring 15 at the other end of the connecting rod 8 rotates in the limiting groove 17 in the second fixed block 14. At the same time, the degree mark 18 on the outer surface of the second fixed block 14 cooperates with the indicator needle 19 on the connecting rod 8. The tilt sensor 16 on the scraper 11 can detect the tilt angle of the scraper 11. According to its matching simulation software, the current tilt angle is fed back in real time. Finally, the first square groove 2 completes the multi-angle adjustment requirements by sliding horizontally in the groove at the bottom, realizing the requirements for different ceramic slurry angles.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
