A printing tray is fixedly connected to the top surface of the printer main body. A scraping component is arranged on the top surface of the printer main body. A cleaning component is arranged inside the scraping component. A collection component is arranged on the bottom surface of the printer main body. A support component is arranged on the bottom surface of the printer main body. By setting the scraping component and the cleaning component, by holding the handle and then pulling it to one side, the movable clamping block can move inside the movable clamping groove, and drive the scraper on the bottom surface of the top plate to scrape the waste adhered to the top surface of the printing tray. And during the movement of the scraper, the fixed connecting plate can move along with the scraper, and the brush can clean some fine debris powders on the top surface of the printing tray, thus realizing the purpose of replacing manual cleaning and avoiding the problems of poor manual cleaning effect and low efficiency in the prior art. However, there are still the following deficiencies in actual use: Starting from reality, when the device performs debris cleaning, it usually needs to wait until the 3D printed model is completely formed and removed before cleaning, resulting in reduced cleaning efficiency. At the same time, after 3D printing is completed, the model cannot be quickly cooled and formed, resulting in the need for subsequent processing to lag behind, reducing the practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a 3D printing post-processing device, including an operating table 1, a printing device 2 and a printing platform 3. The printing device 2 is provided with a mounting column 201 for mounting on the operating table 1. A printing platform 3 is arranged above the operating table 1 and below the printing device 2. Fixing rods 301 are fixedly connected to the four sides of the printing platform 3. An air outlet mechanism 4 is arranged on the operating table 1 for blowing air above the printing platform 3. A collection mechanism 5 is arranged on the operating table 1 outside the printing platform 3 for collecting debris. The printing platform 3 is connected to the collection mechanism 5 through the fixing rods 301.

[0023] Further, as Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the air outlet mechanism 4 includes a movable slot 401. The movable slot 401 is formed on the mounting post 201 and symmetrically arranged on the left and right sides of the operation table 1. A connecting block 402 is slidably arranged in the movable slot 401. A screw rod 403 is threadedly connected to the connecting block 402. The screw rod 403 is rotatably mounted in the movable slot 401 through a bearing. The bottom end of the screw rod 403 is fixedly connected to a motor 404 and fixedly installed on the mounting post 201. One side of the connecting block 402 close to the printing platform 3 is fixedly connected to an air supply pipe 405. An air outlet 406 is installed on one side of the upper end of the air supply pipe 405 close to the printing platform 3. A ventilation chamber 407 is arranged inside the operation table 1 at the bottom end of the air supply pipe 405. A blower 408 is fixedly installed at the bottom of the movable slot 401 at the bottom of the operation table 1. A dust-proof net 409 is fixedly connected to the bottom of the blower 408 at the bottom of the operation table 1. The air supply pipe 405 is slidably arranged on the operation table 1 and penetrates into the operation table 1. The air outlet 406 is arranged above the printing platform 3 through the air supply pipe 405 at a certain height.

[0024] During use, debris is blown by the operation of the blower 408, so that an air flow is formed in the ventilation chamber 407 and discharged through the air supply pipe 405 at the air outlet 406. As a result, the debris is moved by the air flow above the printing platform 3 and moves to the front and rear sides of the printing platform 3, and is collected in the collection mechanism 5. At the same time, as the printing height increases, the motor 404 can be operated to drive the screw rod 403 to rotate at this time, so that the connecting block 402 moves on the screw rod 403, thereby causing the air supply pipe 405 to slide upward, so that the height of the air outlet 406 is adjusted with the printing height. By adjusting, the printed model can be quickly cooled, thereby improving its forming efficiency, facilitating subsequent processing work, and improving its printing efficiency.

[0025] According to the above working process, it can be seen that: after the 3D model is printed and formed by the printing device 2, the air outlet mechanism 4 provided can blow the generated debris at the same time, so that it is collected by the collection mechanism 5, greatly improving the cleaning efficiency of the debris and facilitating the normal progress of the printing work.

[0026] Furthermore, as shown in Figure 2 、 Figure 3 and Figure 4 it is worth specifically explaining that the collection mechanism 5 includes a collection table 501. The collection table 501 is arranged below the printing platform 3 and fixedly connected to the inside of the operation table 1. A collection frame 503 is slidably installed in the collection table 501 and penetrates through the front side of the operation table 1. A guide plate 502 is fixedly connected to the upper part of the collection table 501. The guide plate 502 is arranged in an inclined plane and a gap is left between it and the printing platform 3 for debris to enter the collection frame 503. There is a spaced arrangement between the collection table 501 and the operation table 1.

[0027] During use, through the air outlet mechanism 4, the debris is moved by the airflow above the printing platform 3 and moves towards the front and rear sides of the printing platform 3. Guided by the guide plate 502, it falls into the collection box 503 arranged in the collection table 501 for collection, so that there is no debris above the printing platform 3, thereby ensuring the cleanliness of the printing process.

[0028] This solution has the following working process: When this device is in use, the 3D model of the printing platform 3 is printed on the upper part of the printing platform 3 through the printing device 2. During printing, the generated debris is caused by the operation of the fan 408, so that an air flow is formed in the ventilation chamber 407 and discharged through the air supply pipe 405 at the air outlet 406. As a result, the debris is moved by the air flow above the printing platform 3 and moves towards the front and rear sides of the printing platform 3. Guided by the guide plate 502, it falls into the collection box 503 arranged in the collection table 501 for collection, so that there is no debris above the printing platform 3, thereby ensuring the cleanliness of the printing process. As the printing height increases, at this time, the motor 404 can be operated to drive the screw 403 to rotate, so that the connecting block 402 moves on the screw 403, thereby causing the air supply pipe 405 to slide upward, so that the height of the air outlet 406 is adjusted according to the printing height. By adjusting, the printed model can be quickly cooled, thereby improving its forming efficiency, facilitating subsequent processing work, and improving its printing efficiency.

[0029] In summary: By setting the air outlet mechanism 4, after the printing device 2 forms the 3D model, it can simultaneously blow the generated debris, so that it is collected through the collection mechanism 5, greatly improving the cleaning efficiency of the debris and facilitating the normal progress of the printing work; by setting the air outlet mechanism 4, during the process of printing the 3D model by the printing device 2, the height position of the air outlet can be adjusted to facilitate the rapid cooling of the model, improve its forming efficiency, and then improve its printing efficiency, facilitating subsequent work.
