[0096] In some embodiments, the two frame members 212 (the first frame member and the second frame member) are configured to be driven by the first driving assembly 5 to rotate around the rotation center line of the carrier 21 to adjust the opening and closing of the second opening 211. In some embodiments, the two frame members 212 (the first frame member and the second frame member) are configured to be driven by the first driving assembly 5 to rotate around the rotation center line of the carrier 21 to make the second opening 211 corresponding to the first opening 121.

[0097] In some embodiments, the two frame members 212 are driven to rotate relative to each other around the rotation center line of the carrier member 21 by the first driving component 5 to open the second opening 211, and the two frame members 212 are driven to rotate around the rotation center line of the carrier member 21 by the first driving component 5 to make the second opening 211 correspond to the first opening 121.

[0098] In this embodiment, two first drive components 5 are provided. The first frame component and the second frame component are each provided with a second transmission connector 22. The first frame component is connected to one of the first drive components 5 via the second transmission connector 22, and the second frame component is connected to the other first drive component 5 via the second transmission connector 22, allowing the two frame components 212 to rotate synchronously or relative to each other. The first drive component 5 drives the two frame components 212 to rotate relative to each other around the rotation center line of the support component 21, causing the second opening 211 to open (when the two frame components 212 rotate relative to each other to...). Figure 15 In the indicated state, the second opening 211 is open, and the first drive assembly 5 drives the two frame members 212 to rotate synchronously around the rotation center line of the carrier member 21, so that the second opening 211 corresponds to the first opening 121 (i.e., corresponds to the printing platform 110 that covers the first opening 121). The printed part falls from the second opening 211 into the first frame member. The first drive assembly 5 drives the two frame members 212 to rotate relative to each other around the rotation center line of the carrier member 21, so that the second opening 211 is closed (when the two frame members 212 rotate relative to each other to...). Figure 14 In the indicated state (with the second opening 211 closed), the printed piece is surrounded between the first frame member and the second frame member (i.e., the carrier member 21). The carrier member 21 is rotated around its rotation center line by the first drive assembly 5 (i.e., the two frame members 212 are synchronously rotated around the rotation center line of the carrier member 21 by the first drive assembly 5), thus achieving print rotation. It should be noted that the drive assembly that adjusts the opening and closing of the second opening 211 by relative rotation of the two frame members 212 around the rotation center line of the carrier member 21, and the drive assembly that synchronously rotates the two frame members 212 around the rotation center line of the carrier member 21, can be the same drive assembly or different drive assemblies for the second opening 211 and the first opening 121. It should also be noted that there are two ways to make the two frame members 212 rotate relative to each other: one is that one frame member 212 remains stationary while the other rotates; the other is that the two frame members 212 rotate simultaneously in opposite directions or asynchronously. The first method is preferred for controlling the opening and closing of the second opening 211.

[0099] In this embodiment, as Figure 13As shown, both frame members 212 are semi-cylindrical tubes, nested inside each other and capable of rotating around the rotation center line of the support member 21. Preferably, the rotation center line of the support member 21 is the axis of the semi-cylindrical tube. In some embodiments, only one frame member 212 may have an opening, while the other frame member 212 may be configured as a cover plate structure. By rotating or moving the two frame members 212 relative to each other, the cover plate frame member 212 can approach or move away from the opening of the other frame member 212. When the cover plate frame member 212 approaches and covers the opening of the other frame member 212, the second opening 211 of the support member closes; when the cover plate frame member 212 moves away from the opening of the other frame member 212, the second opening 211 of the support member opens.

[0100] Continue to refer to Figure 15 In this embodiment, the first drive assembly 5 includes a first motor 53 and a first transmission structure. The first transmission structure includes a first drive wheel 54, a first driven wheel 55, and a first belt 56. The first motor 53 is mounted on the post-processing body 1, and the first drive wheel 54 is mounted on the output shaft of the first motor 53. The first driven wheel 55 is connected to the frame component 212 via a first transmission connector 51. The first belt 56 connects the first drive wheel 54 and the first driven wheel 55.

[0101] In the above structure, the first motor 53 drives the frame components to rotate via the first driving wheel 54, the first driven wheel 55, and the first belt 56. By making the two frame components 212 rotate synchronously, the carrier component 21 can be controlled to rotate around the rotation center line, allowing the carrier component 21 to rotate during post-processing such as cleaning, so as to perform efficient and comprehensive post-processing on the printed parts. By making the two frame components 212 rotate relative to each other, the opening and closing, the degree of opening, and the opening position of the second opening 211 can be controlled, so that the second opening 211 opens towards the first opening 121 on the post-processing machine body 1 during the material scraping process, and closes during post-processing such as cleaning, to prevent the printed parts from being thrown out.

[0102] In other embodiments, the opening and closing of the second opening 211 can also be controlled by manually rotating the two frame components 212.

[0103] In some embodiments, the two frame members 212 are in a state where the second opening 211 is open and corresponds to the first opening 121 without any driving force of the driving assembly, or the two frame members 212 rotate or relatively rotate around the rotation center line of the carrier 21 from other states to the state where the second opening 211 is open and corresponds to the first opening 121, and in this state, the two frame members 212 are in a stable and stationary state without any driving force of the driving assembly. In this embodiment, the two frame members 212 rotate or relatively rotate around the rotation center line of the carrier 21 from other states to the state where the second opening 211 is open and corresponds to the first opening 121 due to the action of gravity.

[0104] The carrier assembly 2 is arranged in the processing chamber 11 and corresponds to the first opening 121. In this embodiment, the carrier assembly 2 is in a stable and stationary state without any driving force of the driving assembly, and the second opening 211 is open and corresponds to the first opening 121 (the second opening 211 faces the first opening 121). Of course, the carrier assembly 2 can also be in a stable and stationary state under the driving force of the driving assembly, and the second opening 211 is open and corresponds to the first opening 121 (the second opening 211 faces the first opening 121).

[0105] In some embodiments, the processing chamber 11 is formed with a third opening in the insertion direction of the carrier assembly 2, and the rear processing device 1 is provided with an opening and closing door 16 that covers the third opening. In this embodiment, the insertion direction of the carrier assembly 2 is the front-rear direction of the rear processing device, and the third opening is arranged on the front wall of the processing chamber 11.

[0106] In some embodiments, in order to facilitate the pushing and pulling of the carrier assembly 2, the mounting frame 24 is provided with a push-pull handle 243; when the carrier assembly 2 is inserted into the processing chamber 11, the push-pull handle 243 is located on the side of the mounting frame 24 close to the opening and closing door 16 of the processing chamber 11. When the printing piece processing is completed, the staff can open the opening and closing door 16, and then pull the push-pull handle 243 to take out the carrier assembly 2 from the processing chamber 11. It should be noted that the push-pull handle 243 can also be arranged on the carrier 21.

[0107] When the second opening 211 is in the open state of 180° (i.e. Figure 16(As shown in the diagram), the extension directions of the transmission protrusion 52 and the transmission groove 23 are parallel to the insertion direction, allowing for the installation or removal of the carrier assembly 2. When the second opening 211 is closed or open at other angles, the carrier assembly 2 can only rotate around its rotation center line, resulting in more accurate installation and more efficient operation. Furthermore, when the second opening 211 is open at 180°, the two nested frame members 212 are fully engaged, minimizing the overall height of the carrier assembly 2, thus facilitating the insertion or removal of the carrier member 21 from the post-processing unit 1.

[0108] Reference Figure 2 In some embodiments, the scraping mechanism 3 includes a scraper 31 and a third drive assembly 32, the third drive assembly 32 being used to drive the scraper 31 to move, so as to scrape off the printed parts on the printing platform 110 and allow the printed parts to enter the processing chamber 11.

[0109] Using the above structure, the working process of the scraper mechanism 3 is as follows: After printing is completed, the printing platform 110 is inserted into the first opening 121. At this time, the printed parts (adhered to the printing platform 110) Figure 2 The dotted area in the diagram represents the printed part. At the bottom of the printing platform 110, the second opening 211 of the carrier faces upward and is opposite to the first opening 121. The scraper 31 is located between the carrier and the first opening 121. At this time, the scraper 31 can move horizontally along the printing platform 110 to scrape off the printed part on the printing platform 110. After the scraper mechanism 3 separates the printed part from the printing platform 110, the printed part falls from the second opening 211 onto the carrier 21 under the action of gravity. Then, the cleaning component and the feeding component 6 clean the printed part that has fallen onto the carrier 21.

[0110] Reference Figure 5 and Figure 6 Optionally, a third drive assembly 32 is provided at both ends of the blade 31 along its length to make the blade 31 move more smoothly. In some embodiments, the blade mechanism 3 further includes a guide assembly 33, which includes a guide rail 331 disposed on the post-processing body 1 and a slider 332 slidably connected to the guide rail 331, the slider 332 being connected to the blade 31. Optionally, the guide assembly 33 is provided at both ends of the blade 31 along its length, and the guide assembly 33 can limit the movement trajectory of the blade 31 and prevent the blade 31 from shaking. It should be noted that providing only one third drive assembly 32 can also achieve the purpose of driving the blade 31 to move.

[0111] In some embodiments, the shoveling mechanism 3 further comprises a tensioning assembly 35 for providing elastic force to make the shoveling blade 31 tightly contact the printing platform 110. In the present embodiment, one end of the tensioning assembly 35 is arranged at the shoveling blade 31 and the other end is arranged at the sliding block 332. In the absence of external force, the working end of the shoveling blade 31 is arranged at a height not lower than the height of the forming surface of the printing platform 110 in the state that the printing platform 110 is capped on the first opening 121. Through the above structure, in the state that the printing platform 110 is capped on the first opening 121, the forming surface of the printing platform 110 abuts against the working end of the shoveling blade 31. If the shoveling blade 31 is pressed by the printing platform 110, the reverse force of the tensioning assembly 35 on the shoveling blade 31 makes the working end of the shoveling blade 31 tightly contact the forming surface of the printing platform 110. In some embodiments, the shoveling blade 31 is rotationally connected to the sliding block 332. It should be noted that the tensioning assembly 35 can comprise one or more elastic members such as springs or torsion springs.

[0112] With reference back to Figure 5 and Figure 6 , in the present embodiment, the third driving assembly 32 comprises a third motor 321, a lead screw 322, a third driving wheel 323, a third driven wheel 324 and a third belt 325. The body of the third motor 321 is mounted on the post-processing body 1, and the output shaft of the motor is sleeved with the third driving wheel 323. The lead screw 322 extends along the moving direction of the shoveling blade 31 and is rotationally mounted on the post-processing body 1. One end of the lead screw 322 is sleeved with the third driven wheel 324, and one end of the shoveling blade 31 is directly or indirectly screwed on the lead screw 322. In the present embodiment, the shoveling mechanism 3 comprises a shoveling blade fixing block 34 screwed with the lead screw 322, and one end of the shoveling blade 31 is indirectly screwed on the lead screw 322 through the shoveling blade fixing block 34. The third belt 325 is connected between the third driving wheel 323 and the third driven wheel 324. It should be noted that the shoveling blade fixing block 34 is fixedly connected with the sliding block 332, one end of the elastic member in the tensioning assembly 35 is arranged at the shoveling blade 31 and the other end can be arranged at the shoveling blade fixing block 34, and the shoveling blade 31 can also be rotationally connected to the shoveling blade fixing block 34.

[0113] In some embodiments, the third driving assembly 32 further comprises a tensioning wheel 326 rotationally mounted on the post-processing body 1 and abutting against the third belt 325 to tension the third belt 325.

[0114] The third motor 321 drives the screw 322 to rotate through the third driving wheel 323, the third driven wheel 324 and the third belt 325 in the working process of the shoveling mechanism 3. The screw 322 drives the shoveling blade 31 to translate. As the shoveling blade 31 slowly translates, the printed product on the printing platform 110 is shovelled off and falls into the bearing member. The radius of the third driven wheel 324 is greater than that of the third driving wheel 323. The rotation speed of the third driven wheel 324 is lower than that of the third driving wheel 323. The design can increase the output torque. In the automatic shoveling process, the printed product may be very firmly stuck. The third driven wheel 324 needs to output greater torque to drive the screw 322 to rotate, so that the shoveling blade 31 shovels off the firmly stuck printed product. Moreover, the slower rotation speed improves the stability of the transmission in the shoveling process.

[0115] In other embodiments, the third driving assembly 32 can also be in other driving forms such as hydraulic driving or pneumatic driving. The third driving assembly 32 includes a piston cylinder (which can be a pneumatic piston cylinder or a hydraulic piston cylinder). The cylinder body of the piston cylinder is installed on the post-processing machine body 1. The piston rod of the piston cylinder is connected to the shoveling blade 31. Thus, the piston rod of the piston cylinder drives the shoveling blade 31 to translate in the process of extension and retraction.

[0116] With reference to Figures 7 to 9 In this embodiment, the tensioning assembly 35 specifically includes a compression spring. The two ends of the compression spring are respectively connected to the shoveling blade fixing block 34 and the shoveling blade 31. The shoveling blade fixing block 34 and the shoveling blade 31 are oppositely arranged on one side and are respectively provided with spring limiting grooves. The two ends of the compression spring are respectively inserted into the spring limiting grooves on the shoveling blade fixing block 34 and the shoveling blade 31. The two spring limiting grooves can limit the two ends of the compression spring to avoid falling off.

[0117] In this embodiment, the opposite two sides of the shoveling blade 31 along the width direction are respectively a fixed side and a floating side. The fixed side is rotationally connected to the shoveling blade fixing block 34. The floating side is configured to tightly contact the printing platform 110 under the elastic force of the elastic member. In the above structure, the shoveling blade 31 and the printing platform 110 are in line contact (i.e., only the edge of the floating side contacts the printing platform 110) in the shoveling process.

[0118] In other embodiments, the shoveling blade 31 has a shoveling plane for abutting the printing platform 110. The shoveling plane is configured to integrally contact the printing platform 110 under the elastic force of the elastic member. In the above embodiment, the shoveling blade 31 and the printing platform 110 are in surface contact (i.e., the shoveling plane integrally contacts the printing platform 110) in the shoveling process.

[0119] Compared with the shovel mode of the face contact between the shovel blade 31 and the printing platform 110 in the shoveling process, the shovel mode of the line contact between the shovel blade 31 and the printing platform 110 in the shoveling process is adopted in the embodiment, which reduces the contact area of the shovel blade 31 and the printing platform 110, thereby reducing the moving resistance of the shovel blade 31, and making the movement of the shovel blade 31 more stable and smooth.

[0120] Optionally, the edge of the floating side of the shovel blade 31 is provided with a blade edge 311; and / or, the shoveling mechanism 3 further comprises a transfer shaft 36, and the fixed side of the shovel blade 31 is rotationally connected with the shovel blade fixing block 34 through the transfer shaft 36. In the embodiment, the edge of the floating side of the shovel blade 31 is provided with the blade edge 311, which can tightly adhere to the material loading surface of the printing platform 110 under the elastic force of the tensioning assembly 35 in the shoveling process, and the material on the printing platform 110 can be easily shovelled off due to the sharpness of the blade edge 311. The shoveling mechanism 3 further comprises the transfer shaft 36, which extends along the length direction of the shovel blade 31 and penetrates the fixed side of the shovel blade 31 and the shovel blade fixing block 34, so that the floating side of the shovel blade 31 can rotate around the fixed side of the shovel blade 31.

[0121] Through the above structure, when the printing platform 110 is in the state of covering the first opening 121, the printing platform 110 presses the floating side of the shovel blade 31 downward, at this time, the reverse force of the tensioning assembly 35 on the shovel blade 31 makes the floating side of the shovel blade 31 tightly adhere to the forming surface of the printing platform 110. Since the edge of the floating side of the shovel blade 31 is provided with the blade edge 311, the blade edge 311 can tightly adhere to the forming surface of the printing platform 110 under the elastic force of the tensioning assembly 35 in the shoveling process, and the printing piece on the printing platform 110 can be easily shovelled off due to the sharpness of the blade edge 311.

[0122] Reference Figures 10 to 12In some embodiments, the 3D post-processing device further comprises a drying assembly arranged on the post-processing body 1. In this embodiment, the drying assembly comprises a heater 8 arranged on the air supply channel 42, and a second air passage 152 is formed between the air supply channel 42 and the processing chamber 11, and the air heated by the heater 8 is sent into the processing chamber 11 through the second air passage 152 to perform hot air drying on the printed part. That is, the drying assembly is composed of the heater 8 and the air supply assembly 4, which is used to spray the cleaning material to the surface of the printed part during the cleaning process, and is used to provide hot air to the processing chamber 11 during the drying process to dry the printed part. Of course, the heater 8 can also not be arranged on the air supply channel 42, and the air supply assembly 4 can be used to supply air to the processing chamber 11 for air drying; two sets of air supply assemblies 4 can also be arranged, one set for cleaning and the other set for drying; in addition, the drying assembly can also be direct heating, infrared heating or other heating forms, without warm air heating through the air supply assembly 4.

In this embodiment, the heater 8 is preferably a PTC heater 8.

[0123] In the above arrangement, the air supply assembly 4 has two working modes. The first working mode of the air supply assembly 4 is the cleaning mode, specifically: during the cleaning process, the air flow control member 41 (which can be a blower) sends air into the air supply channel 42, and the air is sprayed out of the first air passage along the air supply channel 42, and the impact force of the gas is used to spray the cleaning liquid in the cavity to the surface of the printed part to wash the printed part; in this working mode, the heater 8 can work or not work. The second working mode of the air supply assembly 4 is the drying mode, specifically: after the cleaning is completed, the heater 8 works, and the blower sends air into the air supply channel 42, and the air is heated by the heater 8 when passing through the heater 8, and the heated air is sent in from the second air passage 152 to dry the printed part.

Figure 2 and Figure 8As shown, the working end of the scraper 31 is tightly attached to the forming surface (i.e. the side carrying the printed part) of the printing platform 110 under the reverse force of the tensioning component 35. Before the shovel mechanism 3 shovels material, the control device controls the first drive assembly 5 to drive the two frame components 212 to rotate relative to each other, so that the second opening 211 of the bearing component 21 opens and faces the first opening 121 (e.g., Figure 2 (As shown); then, the control device controls the third drive assembly 32 to drive the scraper 31 to move horizontally along the printing platform 110 to scrape off the printed parts on the printing platform 110.

After cleaning, the control device controls the first control valve, airflow control element 41 and heater 8 on the air supply channel 42 to open. The airflow control element 41 sends air to the heater 8 for heating. Hot air is sprayed from the air inlet 142 into the processing chamber 11 and dries the clean printed parts. At this time, the carrier 21 will continue to rotate to make the printed parts dry more thoroughly. During the cleaning and drying of the printed object, the air passage 18 at the top of the post-processing machine body 1 can ensure the air in and out of the processing chamber 11; After the drying is completed, the control device controls the first driving assembly 5 to drive the two frame members 212 to rotate relative to each other, so that the second opening 211 of the carrier 21 is opened by 180° (as shown in Figure 16 The opening and closing door 16 is opened, and the mounting rack 24 and the carrier 21 connected thereto are taken out; at the same time, the conveying device 200 puts the printing platform 110 back on the printer body 120, and waits for the next printing operation.
