A fixed frame is installed on the surface of the first bevel gear 52, and the top of the fixed frame is fixedly connected to the two groups of fixed rings 536 respectively. The fixed ring 536 is fixedly connected to the body 1. The fixed ring 536 provides support for the rotating rod 53 and provides stability for the first bevel gear 52. The connecting piece 58 is connected to the connecting ring 42. Through the rotation of the first bevel gear 52, the second bevel gear 54 and the third bevel gear 55 can be driven to move in opposite directions. The positive and negative rotations can increase the contact area between the printed part and the polishing material, thereby improving the polishing degree of the printed part. A feed port is opened on the surface of the cover plate 41, and the top cover is not shown in the figure.

[0031] A pipe 574 is provided inside the rotating rod 53 and the airbag 57, and they are connected. An air pump 573 is installed at the other end of the rotating rod 53, which is away from the airbag 57. The air pump 573 is located inside the body 1. The airbag 57 and the air pump 573 are connected through the pipe 574. The size of the airbag 57 can be changed through the air pump 573 to adapt to prints of different specifications, and the contact area with the prints can be increased, thereby improving the smoothness of the surface of the prints.

[0032] A sleeve rod 56 is fixedly connected to one side of the third bevel gear 55, and the sleeve rod 56 is movably connected to the rotating rod 53. The sleeve rod 56 is located at an end away from the second bevel gear 54. The movably connected sleeve rod 56 and the rotating rod 53 can realize a motor 51 driving the connecting piece 58 and the airbag 57 to rotate synchronously in the opposite direction, so as to improve the polishing speed and quality.

[0033] The connecting member 58 includes a load-bearing rod 581 fixed on the surface of the sleeve rod 56, and a connecting plate 583 is movably connected to the inner side of the load-bearing rod 581. Slide blocks 585 are fixedly connected to both sides of the connecting plate 583. A slide groove 582 is opened on the inner side of the load-bearing rod 581. The slide block 585 is located inside the slide groove 582 and is movably connected thereto to improve the stability of the connecting plate 583 when moving.

[0034] The bottom of the connecting plate 583 is fixedly connected with a connecting column 584, which is located inside the connecting ring 42 and is movably connected thereto. The inside of the load-bearing rod 581 is rotatably connected with a screw 586, which is located inside the connecting plate 583 and is threadedly connected thereto. The top of the screw 586 extends to the top of the load-bearing rod 581 for easy operation. The screw 586 is used to drive the lifting and lowering of the connecting plate 583, and a circular array of connecting holes is provided on the surface of the connecting ring 42. The connecting column 584 is located inside the connecting hole, and the connecting hole and the connecting column 584 are each provided with three groups to form a triangular structure to enhance stability. The connecting piece 58 is connected to the roller 4 through the connecting ring 42, which can increase the stability and firmness of the roller 4, thereby avoiding the shaking and deformation of the roller 4 during operation.

[0035] During use, the polishing material and the printed work are placed inside the roller 4 through the feed port on the surface of the cover plate 41, and then it is sealed through the top cover. Then, according to the specifications of the printed work, the air pump 573 is started to transport the gas to the inside of the airbag 57 through the pipeline 574, so that it slowly expands until the gap between the airbag 57 and the polishing material is minimized. Then, the motor 51 is started to drive the first bevel gear 52 to rotate, and the second bevel gear 54 and the third bevel gear 55 are driven to rotate through the first bevel gear 52. During the rotation, the second bevel gear 54 will drive the rotating rod 53 and the airbag 57 to rotate, so that the airbag 57 rotates along the inside of the roller 4. During the rotation, the third bevel gear 55 will drive the cover plate 41 to rotate in the opposite direction along the surface of the rotating rod 53, so that The roller 4 rotates along the surface of the auxiliary roller 3 and rotates in the opposite direction to the airbag 57. During this period, the airbag 57 rotates in the opposite direction to the roller 4. The resulting movement can make the polishing material and the silicone block 571 placed inside the roller 4 move relative to each other, so that the polishing effect is uniform, and the inflatable airbag 57 can compress the polishing material placed inside the roller 4 and move the silicone block 571 toward the polishing material, thereby generating a high-pressure rotating polishing effect, thereby making the polishing effect stronger. In summary, the airbag 57 rotates in the opposite direction to the roller 4, the polishing efficiency is higher, and the polishing is sustainable, so that the printed part can be polished efficiently in a short time, thereby solving the problem of uneven polishing of the printed part surface or substandard surface quality caused by uneven distribution of the polishing material;

[0036] When positioning the cover plate 41, the screw rod 586 is directly screwed to make it rotate along the inside of the load-bearing rod 581, and drive the connecting plate 583 to descend, so that the connecting plate 583 descends along the inside of the slide groove 582 through the slider 585, which can make it more stable when moving, until the connecting clamping column 584 at the bottom of the connecting plate 583 is completely fitted with the connecting hole on the surface of the connecting ring 42, so that the stability and firmness of the Zhengjia roller 4 can be ensured, and the problem of deformation of the roller 4 during operation is further avoided. Moreover, since the connecting ring 42 is fixedly connected to the cover plate 41, there is no need to drill holes directly on the surface of the cover plate 41, so it will not affect the structural integrity and safety of the cover plate 41.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
