[0021] The driving shaft 32 and the driven shaft 33 are provided to drive the conveyor belt 34 to perform a circular motion, and due to the structure of the driving shaft 32 and the driven shaft 33, the end of the conveyor belt 34 is an arc-shaped structure, which is more conducive to the separation of the printed parts. If the printed parts are not separated from the conveyor belt 34, the installed shovel assembly 5 can also be used to forcibly separate the printed parts, and the separated printed parts will fall into the collection box 8 for collection. The residual material on the conveyor belt 34 during the circulation process can be cleaned by the provided belt pressing assembly 6, and the conveyor belt 34 can be smoothed after passing through the belt pressing assembly 6, thereby ensuring that the conveyor belt 34 in the printing area is closely fitted with the hot bed plate 2, and the provided printing assembly 7 can realize printing in three-dimensional space.

[0022] The driving assembly 4 includes a driving motor 41 , which is fixedly connected to the heated bed mounting frame 11 . The driving motor 41 is disposed below the heated bed plate 2 , and a driving wheel 42 is fixedly connected to an output end of the driving motor 41 .

[0023] A driving belt shaft 31 is fixedly connected to the driving shaft 32, and the driving belt shaft 31 is arranged in the middle of the driving shaft 32. A driving belt 43 is connected to the driving belt shaft 31 and the driving wheel 42. A belt groove 13 is opened on the mounting shaft frame 12, and the driving belt 43 is arranged through the belt groove 13.

[0024] The driving motor 41 is provided to drive the driving wheel 42 to rotate, and the power is transmitted to the driving belt shaft 31 through the transmission belt 43, thereby driving the driving shaft 32 to rotate, thereby realizing the overall movement of the conveyor belt 34.

[0025] The shoveling assembly 5 includes a shoveling inclined plate 51, and both ends of the shoveling inclined plate 51 are fixedly connected to a side fixing plate 52. The two side fixing plates 52 are each provided with a first positioning mounting hole 53. The two side fixing plates 52 are fixedly connected to a mounting shaft frame 12 through the first positioning mounting hole 53. The shoveling inclined plate 51 is set close to the conveyor belt, and the shoveling inclined plate 51 is set tangent to the arc surface of the conveyor belt.

[0026] The shovel inclined plate 51 fits tightly with the conveyor belt 34 and is tangent to the arc surface of the conveyor belt 34, which can effectively shovel the printed parts on the conveyor belt 34, facilitate the separation of the printed parts, and achieve the purpose of automatic separation and collection of the printed parts.
