Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic slurry 3D printing, and in particular relates to a feeding and scraping mechanism and a printer used for ceramic slurry 3D printing. Background Art

[0002] In the printing process of the sinking light-curing ceramic slurry 3D printing equipment, feeding and scraping are the key processes to ensure the quality of printed parts.

[0003] The feeding and scraping process of existing ceramic slurry 3D printing equipment is as follows: first, the slurry is transported from the storage area to the feeding area by a peristaltic pump; second, the scraper is lifted and moved to the back of the slurry in the feeding area; third, the scraper is lowered and starts scraping, starting from the feeding area, passing through the molding area and finally moving to the overflow position to wait for printing; fourth, the laser starts scanning in the molding area, and the current printed layer is solidified and formed; fifth, after the current layer is printed, the molding table is lowered by one layer thickness, and the above steps are repeated to print the next layer until all layers are printed.

[0004] In the existing process, the scraper moves to the back of the slurry in the feeding area and needs to avoid the slurry accumulated in the feeding area, so the scraper must add a mechanical action of lifting and lowering the scraper, which will introduce repeated positioning errors of the scraper, resulting in an increase in the difference range of the thickness of each layer and a large deviation in the plane accuracy. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides a feeding and scraping mechanism and a printer for ceramic slurry 3D printing. Through the setting of the feeding and scraping mechanism, the problem of repeated positioning errors of the scraper caused by the lifting and lowering actions of the scraper is solved, and the steps of lifting and lowering the scraper are eliminated. A first leveling part is added accordingly. During the movement of the scraper, there is no need to avoid the ceramic slurry supplied from the feeding bin, and the parallelism of the leveling scraper and the molding surface not only reduces the introduction of errors, but also can eliminate mechanical processing and assembly errors through the first leveling part, effectively ensuring the consistency of the thickness of each printed layer and greatly improving the plane accuracy.

[0006] The technical effect to be achieved by the utility model is achieved through the following technical solutions:

[0007] A feeding and scraping mechanism for ceramic slurry 3D printing, comprising a fixed seat, provided with a receiving cavity; a feeding component, embedded and connected to the receiving cavity; and a scraping component, arranged in parallel with the feeding component and connected to the fixed seat;

[0008] The scraping component includes a scraper portion and a first leveling portion, wherein the first leveling portion is arranged at both ends of the scraper portion; the scraper portion is connected to the fixing seat, one end of the first leveling portion is connected to the scraper portion, and the other end of the first leveling portion is connected to the fixing seat.

[0009] The feeding part is used to supply ceramic slurry. The scraping part is used to scrape the ceramic slurry discharged from the feeding part evenly on the surface of the molding surface. The first leveling part is used to adjust the parallelism between the scraper part and the molding surface, so as to reduce the introduction of errors of the scraper part.

[0010] In the utility model, the feeding component and the scraping component are arranged side by side. After the feeding component has discharged material for a certain period of time, the scraping component can move at the same time, and the scraping component follows the movement of the feeding component to scrape the material. This design can eliminate the lifting and lowering actions of the scraping component, effectively simplify the operation process, and improve the rhythm of the operation.

[0011] Wherein, weight-avoiding cavities are arranged on both sides of the fixing seat, and the weight-avoiding cavities are arranged on both sides of the accommodating cavity. Through this arrangement, the weight of the feeding scraping mechanism can be effectively reduced while meeting the strength requirements, and the portability of the mechanism design can be met.

[0012] And by setting the first leveling part, before printing, the two ends of the scraper part are adjusted by the first leveling part so that the scraper part is adjusted to be parallel to the molding surface, thereby effectively reducing the introduction of scraper part errors, effectively ensuring the consistency of the thickness of each printed layer, and greatly improving the plane accuracy. At the same time, the first leveling part also eliminates mechanical processing and assembly errors, with a wide range of applications and high flexibility.

[0013] Furthermore, the first leveling part includes a fixed block, a first adjusting rod and a guide block, the fixed block is fixedly connected to the scraper part, the guide block is fixedly connected to the fixed seat, and the first adjusting rod passes through the fixed block and is arranged corresponding to the guide block.

[0015] The action of the first leveling part to adjust the scraper part upward is: loosen the connection between the scraper part and the fixed seat, rotate the first adjusting rod, so that the first adjusting rod moves down to support the top of the guide block; since the guide block is fixedly connected to the fixed seat, the first adjusting rod moves the scraper part upward to realize the upward movement of the scraper part; after the upward movement is completed, the scraper part and the fixed seat are locked.

[0016] The first leveling part adjusts the scraper part downward by: rotating the first adjusting rod in the opposite direction so that the first adjusting rod moves upward, and the scraper part moves downward under the gravity, so as to realize the downward movement of the scraper part, and then locking the scraper part and the fixing seat after the downward movement is completed.

[0017] By adjusting the distance between the scraper part and the molding surface, the distance and parallelism between the scraper and the molding surface can be adjusted. The operation is simple and quick. The position of the scraper part can be flexibly adjusted according to actual printing needs to adapt to various needs with high flexibility.

[0018] Furthermore, the scraping components are arranged on both sides of the feeding component and are fixedly connected to the fixing seat. With this arrangement, the feeding component is located in the middle, and the scraping components are installed on both sides. After the feeding component discharges materials for a certain period of time, the scraping components can move at the same time and follow the movement of the feeding component to scrape the materials, so that two-way feeding can be realized, effectively shortening the time of feeding and scraping materials, and improving printing efficiency.

[0019] Furthermore, the first adjustment rod is a micrometer head adjustment rod. The micrometer head is a measuring instrument that reads the axial movement of the micrometer screw and has an installation position. Through this setting, the movement of the first adjustment rod can be accurately grasped to ensure the accuracy of the scraper position adjustment.

[0020] Furthermore, the scraper part includes a blade body and a scraper frame, wherein the blade body is fixedly connected to the lower end of the scraper frame. The lower end of the blade body is inclined, which can reduce the contact area between the bottom surface of the blade body and the slurry and reduce the adhesion of the blade body while ensuring the structural strength of the blade body.

[0021] Furthermore, the scraper frame includes a frame body and a mounting groove, wherein the mounting groove is arranged at the lower end of the frame body corresponding to the blade body. The mounting groove is used as an installation reference, and the blade body can be quickly installed by inserting the blade body into the mounting groove and then fixedly connected, so that the installation position of the blade body can be quickly found, the installation is simple and efficient, and it is also convenient for subsequent updating and maintenance of the blade body.

[0022] Furthermore, the feeding component includes a feeding part and a second leveling part, and the second leveling part is fixedly connected to both ends of the feeding part. The second leveling part drives the feeding part to adjust up and down, so as to change the distance between the feeding part and the molding surface, thereby ensuring the quality of the feeding.

[0023] Furthermore, the feeding part includes a feeding bin and a cover plate, the cover plate is connected to the upper end of the feeding bin; the feeding bin includes a bin body, a material loading cavity and a material discharging slit, the material loading cavity is arranged on the bin body, the material discharging slit is arranged under the bin body, and the material discharging slit is communicated with the material loading cavity.

[0024] The cover plate is provided with a feed port and an observation window. To ensure that the liquid level of the feeding silo quickly reaches the same height in the length direction, there are no less than 3 feed ports. To facilitate observation of the storage conditions, there are no less than 2 observation windows, which are made of transparent plexiglass.

[0025] One end of the material placement cavity communicating with the material discharging slit is in an arc shape, which is convenient for cleaning after the slurry flows.

[0026] The depth of the discharge seam is 15-20mm. This setting, combined with the existing positive pressure feeding system, can effectively improve the accuracy of the feeding amount and reduce material waste.

[0027] Through the arrangement of the above-mentioned feeding part, the feeding process is to inject the slurry into the placing cavity, and then use the existing positive pressure feeding system to make the slurry discharged through the discharge slit after being pressurized. Through this operation, the convenience of discharging is improved, the accuracy of the feeding amount is guaranteed, and the waste of slurry is greatly avoided.

[0028] Furthermore, the second leveling part includes an adjustment block and a second adjustment rod, the second adjustment rod penetrates and connects the adjustment block, and the second adjustment rod is arranged corresponding to the fixing seat. The adjustment block is an inverted L-shaped adjustment block. The second adjustment rod is a micrometer adjustment rod to ensure the precise adjustment of the distance between the feeding part and the forming surface.

[0029] Through the above arrangement, the adjustment action of the second leveling part is to rotate the second adjustment rod so that the lower end of the second adjustment rod is pressed against the fixed seat, so that the adjustment block drives the feeding part to move upward, thereby increasing the distance between the feeding part and the forming surface. Conversely, the second adjustment rod is rotated in the opposite direction, and the lower end of the second adjustment rod is away from the fixed seat, that is, the second adjustment rod moves upward, and the feeding bin moves downward under gravity, thereby reducing the distance between the feeding bin and the forming surface. The adjustment process is simple and quick, ensuring the parallelism between the feeding bin and the forming surface, improving the balance of the discharge, and ensuring the discharge quality.

[0030] The printer includes the above-mentioned feeding and scraping mechanism. The setting of the printer can effectively improve the printing efficiency and ensure the printing quality at the same time.

[0031] To sum up, the utility model has at least the following benefits: through the setting of the feeding and scraping mechanism, the problem of repeated positioning errors of the scraper caused by the lifting and lowering actions of the scraper is solved, the steps of lifting and lowering the scraper are eliminated, and the first leveling part is added accordingly.
