The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a sandblasting and polishing device for printed parts, such as... Figure 1-5 As shown, the sandblasting and polishing device for printed parts includes: a processing box 1 for polishing the printed parts; a fixing seat 2 assembled in the processing box 1 for fixing the printed parts; a spray gun 3 assembled on the processing box 1 for sandblasting the printed parts fixed on the fixing seat 2; and a cleaning mechanism assembled on the processing box 1 for cleaning the surface of the polished printed parts.

[0024] In this embodiment, the device is equipped with a controller of model ZEN-10C1AR-A-V2. The controller can control the entire device. The spray gun 3 is connected to the corresponding sandblasting equipment. When polishing the 3D printed parts, the printed parts are fixed on the fixed base 2, the baffle on the processing box 1 is closed, and the spray gun 3 is started. The sand sprayed by the spray gun 3 comes into contact with the surface of the printed parts, thereby polishing the surface of the printed parts. After sandblasting and polishing is completed, the cleaning mechanism is started by controlling the start of the cleaning mechanism to clean the dust and impurities remaining on the surface of the polished printed parts. There is no need for the staff to perform separate cleaning operations afterward, which reduces the overall complexity of the printed parts processing, reduces the operational burden of the staff, and improves work efficiency and ease of operation.

[0025] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a cleaning pipe 4 fixedly installed on the inner rear wall of the processing box 1 and having multiple collection ports; a collection box 5 fixedly installed on the outer rear wall of the processing box 1, wherein a collection filter bag 6 for collecting dust and impurities is provided inside the collection box 5; a connecting pipe 7 fixedly installed on the outer rear wall of the processing box 1, wherein both ends of the connecting pipe 7 are respectively connected to the collection box 5 and the cleaning pipe 4; and a fan 8 mounted on one side of the collection box 5, wherein the air inlet of the fan 8 is connected to the collection box 5.

[0026] In this embodiment, when using the cleaning mechanism, the fan 8 is activated by the controller to generate negative pressure. Under the action of negative pressure, the dust and impurities remaining on the surface of the polished printed parts are sucked into the cleaning pipe 4. Then, the dust and impurities are carried by the airflow through the connecting pipe 7 into the collection box 5. The collection box 5 is equipped with a collection filter bag 6. The dust and impurities are intercepted and collected by the collection filter bag 6, while the air is discharged from the air outlet of the fan 8 through the collection filter bag 6. This completes the cleaning operation of the dust and impurities remaining on the surface of the polished printed parts, eliminating the need for staff to perform separate cleaning operations afterward. This reduces the overall complexity of the printed parts processing, alleviates the operational burden on staff, and improves work efficiency and ease of operation.

[0027] In a further preferred embodiment of this utility model, a rotating mechanism is provided on the processing box 1 and the fixed base 2. The rotating mechanism is used to drive the printed part fixed on the fixed base 2 to rotate. The rotating mechanism includes: a mounting base 9 fixedly installed inside the processing box 1, a mounting shaft 11 rotatably mounted on the mounting base 9, the top end of the mounting shaft 11 being fixedly connected to the bottom of the fixed base 2; and a first servo motor 10 fixedly installed on the mounting base 9, the output shaft of the first servo motor 10 being connected to the bottom end of the mounting shaft 11 through a coupling.

[0028] In this embodiment, when polishing the surface of the printed part, the first servo motor 10 is started by the controller, and its output shaft drives the mounting shaft 11 to rotate through the coupling, thereby driving the fixed base 2 and the printed part fixed on the fixed base 2 to rotate together, thereby uniformly polishing the surface of the printed part and improving the polishing effect of the printed part surface.

[0029] In a further preferred embodiment of this utility model, a protective mechanism is provided on the processing box 1. The protective mechanism is used to protect the cleaning pipe 4. The protective mechanism includes: a protective frame 12 fixedly installed on the inner rear wall of the processing box 1, with the cleaning pipe 4 located inside the protective frame 12; and an electric telescopic rod 14 fixedly installed on the processing box 1. A protective plate 13 is fixedly installed on the output shaft of the electric telescopic rod 14. The protective plate 13 is in contact with one side of the protective frame 12, and the protective plate 13 is used to shield the protective frame 12.

[0030] In this embodiment, when polishing the printed parts, the protective plate 13 is located on one side of the protective frame 12, shielding the cleaning tube 4 inside the protective frame 12 to prevent sand particles or other debris from entering the cleaning tube 4 during sandblasting. When cleaning is required, the electric telescopic rod 14 is activated to move the protective plate 13 away from the protective frame 12 and no longer shield the protective frame 12. At this time, the collection port of the cleaning tube 4 is exposed, and dust and impurities on the surface of the printed parts can be normally adsorbed and collected.

[0031] In a further preferred embodiment of this utility model, a feeding rack 15 is symmetrically arranged on the processing box 1. The feeding rack 15 is used to guide the sand used for polishing the printed parts to the bottom of the processing box 1. A sealing mechanism is provided between the processing box 1 and the two feeding racks 15. The sealing mechanism is used to seal the two feeding racks 15.

[0032] In this embodiment, the function of the unloading rack 15 is to guide the sand used for polishing the printed parts to the bottom of the processing box 1, so as to facilitate the collection and subsequent processing of the sand. When the sandblasting and polishing operation is in progress, the unloading rack 15 is in the open state, so as to facilitate the guiding of the sand used for polishing the printed parts to the bottom of the processing box 1. When it is necessary to clean the surface of the polished printed parts, the unloading rack 15 is sealed by the sealing mechanism, so as to facilitate the cleaning treatment of the polished parts surface.

[0033] In a further preferred embodiment of the present invention, the sealing mechanism includes: a rotating shaft 17 rotatably mounted on the processing box 1 and the two unloading racks 15, two stops 16 fixedly sleeved on the rotating shaft 17, the two stops 16 respectively being adapted to the inner walls of the two unloading racks 15; and a second servo motor 18 fixedly mounted on the outer wall of one side of the processing box 1, the output shaft of the second servo motor 18 being connected to one end of the rotating shaft 17 via a coupling.

[0034] In this embodiment, when performing sandblasting and polishing, the second servo motor 18 is started, causing its output shaft to drive the rotating shaft 17 to rotate, thereby causing the stop block 16 to rotate away from the position that is in contact with the inner wall of the unloading rack 15. At this time, the stop block 16 is released from the blockage of the unloading rack 15, thus facilitating the delivery of the sand used for polishing the printed parts to the bottom of the processing box 1. When it is necessary to clean the surface of the polished printed parts, the second servo motor 18 is started again, causing its output shaft to drive the rotating shaft 17 to rotate in the opposite direction. The stop block 16 then rotates to the position that is in close contact with the inner wall of the unloading rack 15, blocking the channel of the unloading rack 15, thus facilitating the cleaning of the polished parts surface.

[0035] In a further preferred embodiment of the present invention, a guide rod 19 is fixedly installed on the rear inner wall of the processing box 1, and a guide block 20 is fixedly installed on the protective plate 13. The guide block 20 and the guide rod 19 are slidably connected.

[0036] In this embodiment, when the protective plate 13 moves, the protective plate 13 will drive the guide block 20 to slide along the guide rod 19, thereby improving the stability of the protective plate 13 when it moves.

[0037] In a further preferred embodiment of the present invention, a slider is fixedly installed at the bottom of the fixed base 2, and the ball nested at the bottom of the slider is in contact with the bottom of the mounting base 9.

[0038] In this embodiment, during the rotation of the fixed base 2, the ball bearings roll along the bottom of the mounting base 9, providing auxiliary support and guidance for the rotation of the fixed base 2, so that the fixed base 2 can rotate more smoothly and steadily, thereby driving the printed parts fixed on it to rotate stably.

[0039] In summary, compared with related technologies, this device can perform sandblasting and polishing on 3D printed parts, and can also clean the surface of the polished printed parts, reducing the overall complexity of the printed parts processing, while also reducing the operational burden on staff and improving work efficiency and ease of operation.
