Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] The following is further described in conjunction with specific embodiments. Figure 1-Figure 5As shown, the utility model is a self-cleaning denture 3D printing device, comprising a body 1, a mounting frame 2, a printer head 3 and a base 4, wherein the mounting frame 2 is fixedly mounted in the body 1, the printer head 3 is arranged on the mounting frame 2, and the base 4 is mounted at the bottom of the body 1 and is located below the printer head 3. A cleaning mechanism 5 is also arranged in the body 1, and the cleaning mechanism 5 comprises a scraper assembly 51, a support beam 52 for supporting the scraper assembly 51, and a driving assembly 53 for driving the support beam 52 to move. After each printing process is completed, the driving assembly 53 drives the support beam 52 to move along the length direction or width direction of the base 4 as a whole, and after each movement, the position of the scraper assembly 51 on the support beam 52 is adjusted and fixed, so that the movement track of the scraper assembly 51 covers the printing area, that is, the residual material on the base 4 after printing is completed can be cleaned, so that the base 4 is kept clean for the next use.

[0025] Reference Figure 1 , Figure 2 As shown, the self-cleaning denture 3D printing device disclosed in this embodiment also includes a waste collection trough 6, a part of the waste collection trough 6 is located in the machine body 1, and the other part is located outside the machine body 1. The part located in the machine body 1 is a guide section 61, and the part located outside the machine body 1 is a receiving section 62. The guide section 61 extends downwardly from the side close to the base 4 to the side close to the receiving section 62. After the cleaning mechanism 5 scrapes the residual material from the base 4, the residual material can fall into the guide section 61 and enter the receiving section 62 through the guide section 61, so as to facilitate the collection of the residual material. Both sides of the waste collection trough 6 are configured with arc-shaped spring pieces 63. When the waste collection trough 6 is clamped on the machine body 1, the arc-shaped spring pieces 63 can be deformed and pressed against the machine body 1, so as to keep the waste collection trough 6 fixed on the machine body 1. When the waste collection trough 6 is full of residual material, the staff can remove the waste collection trough 6 by force to pour out the collected residual material.

[0026] Reference Figure 3 , Figure 4As shown, the scraper assembly 51 includes a scraper seat 511, which is slidably connected to the support beam 52. A positioning member 514 is provided on the scraper seat 511. A plurality of positioning holes 521 for the positioning member 514 to be inserted are distributed along the length direction of the support beam 52. The positioning member 514 includes a positioning rod 5141 and a positioning sheet 5142. The positioning rod 5141 is composed of a cylindrical section and a conical section integrally formed at the bottom end of the cylindrical section. The diameter of the bottom end of the conical section is smaller than the diameter of the positioning hole 521, so that the positioning rod 5141 can be easily inserted into the positioning hole 521. The cylindrical section and the positioning hole 521 are tightly matched, so that the positioning rod 5141 is not easy to slide out after being inserted into the positioning hole 521. A scraper plate 512 is rotatably installed on one side of the bottom of the scraper seat 511, and a tightening member 513 is arranged on the upper part of the scraper plate 512 for driving the bottom end of the scraper plate 512 to obliquely abut against the base 4. Under the action of the pressing member 513, the scraper plate 512 is pressed against the base 4 and is inclined at a certain angle to the base 4. When the support beam 52 is driven by the driving assembly 53 to move, the scraper seat 511 drives the scraper plate 512 to move synchronously and scrapes off the materials remaining on the base 4. Compared with the method of making the scraper plate 512 in a vertical state and scraping off the residual materials, setting the scraper plate 512 in an inclined state can maintain the fit between the bottom of the scraper plate 512 and the base 4, thereby improving the scraping effect of the residual materials.

[0027] Reference Figure 3 As shown, the driving assembly 53 includes a driving seat 531, a driving motor 532, a lead screw 533 and a driving block 534. The lead screw 533 is rotatably connected in the driving seat 531. The driving motor 532 is installed at one end of the driving seat 531 and can drive the lead screw 533 to rotate. The driving block 534 is slidably installed in the driving seat 531 and is threadedly connected to the lead screw 533. One end of the support beam 52 is fixedly connected to the driving block 534. The lead screw 533 is driven to rotate by the driving motor 532, that is, the driving block 534 can drive the support beam 52 to slide along the length direction of the driving seat 531, thereby driving the scraper assembly 51 to scrape the residual materials on the base 4. A guide member 54 is also provided in the body 1 and located on a side of the base 4 away from the driving assembly 53. The guide member 54 includes two fixed blocks 541, a guide rod 542 fixedly connected between the two fixed blocks 541, and a guide block 543 slidably mounted on the guide rod 542. The length direction of the guide block 543 is consistent with the length direction of the lead screw 533. One end of the support beam 52 away from the driving block 534 is fixedly connected to the guide block 543. When the driving assembly 53 drives the support beam 52 to move, the guide member 54 can support and guide the support beam 52, thereby improving the reliability and stability of the support beam 52 during the sliding process.

[0028] Reference Figure 4As shown, the top end of the scraper plate 512 is rotatably connected to the scraper seat 511, and the bottom end of the scraper plate 512 is provided with a scraper slope 5121, so as to better scrape the residual materials; the abutting member 513 includes an abutting seat 5131, and a torsion spring 5132 is connected between the abutting seat 5131 and the scraper plate 512 for driving the scraper plate 512 to flip downward and abut against the base 4. Under the elastic force of the torsion spring 5132, the scraper plate 512 has a tendency to move downward in an inclined manner, so that it can abut against the base 4. When the driving assembly 53 drives the scraper assembly 51 to move as a whole, the scraper plate 512 can maintain a state of pressing downward against the base 4, so that the scraper slope 5121 at the bottom of the scraper plate 512 can conveniently scrape the residual materials.

[0029] Since the adhesion between the residual material and the base 4 may be different after each printing process, it is necessary to provide a pressing force between the scraper plate 512 and the base 4 for some residual materials with strong adhesion. In order to facilitate the adjustment of the pressing force of the scraper plate 512, the pressing seat 5131 is hingedly arranged on the scraper seat 511, and the upper part of the pressing seat 5131 is provided with an adjusting member 515 for adjusting the inclination angle of the pressing seat 5131.

[0030] Reference Figure 4 , Figure 5 As shown, the adjusting member 515 includes a supporting block 5151, which is fixed on the scraper seat 511 and located on the upper part of the clamping seat 5131. The supporting block 5151 is internally threadedly connected with an adjusting bolt 5152. A limiting block 5153 is provided at the bottom end of the adjusting bolt 5152. A limiting groove 5133 is provided on the clamping seat 5131 for the limiting block 5153 to slide. Under the action of the limiting block 5153 and the limiting groove 5133, the position of the clamping seat 5131 can be fixed after each adjustment of the adjusting bolt 5152 is completed. When it is necessary to scrape off residual materials with strong adhesion, tighten the adjusting bolt 5152 and move the limit block 5153 at the bottom of the adjusting bolt 5152 downward, thereby driving the clamping seat 5131 to rotate downward. When the clamping seat 5131 rotates downward, the deformation degree of the torsion spring 5132 will be increased, so that the torsion spring 5132 can apply a greater downward force to the scraper plate 512, thereby increasing the clamping force between the scraper plate 512 and the base 4.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
