As an embodiment of the invention, a bent protection plate 61 is arranged at the top end of the second arc-shaped plate 6, the protection plate 61 can protect the side surface of the driven wheel 4 close to the driving wheel 3, and the top end of the first arc-shaped plate 5 is provided with an inclined plate 51 which is gradually far away from the driven wheel 4; in operation, because the material on the driven wheel 4 near the driving wheel 3 is easy to adhere to the outer surface of the second gear 41 or between two adjacent second gear 41 when directly contacting the second gear 41, thereby influencing the matching action of the second gear teeth 41, the first gear teeth 31 and the conveying groove 32, and at the moment, by arranging a bent protection plate 61 at the top end of the second arc-shaped plate 6, so that the protection plate 61 can protect the side surface of the driven wheel 4 close to the driving wheel 3, reduce the contact of the material with the second gear teeth 41 at the position and enable the material to be more accurately and effectively matched with the first gear teeth 31 and the conveying groove 32, the inclined plate 51 that sets up simultaneously can play the guide effect and make its smooth efficient whereabouts to the conveyer trough 32 position department on action wheel 3 top to the inside material of storage case 1 to the effectual conveying quality who improves storage case 1.

As an embodiment of the invention, the outer edges of the first gear tooth 31 and the second gear tooth 41 are in arc transition, and the outer end of the scraper 36 is always located inside the conveying trough 32 in the process of movement; the during operation, through setting the form of circular arc transition to the outward flange department with a teeth of a cogwheel 31 and a teeth of a cogwheel 41, can make a teeth of a cogwheel 31 and a teeth of a cogwheel 41 carry out more easily effectual meshing and effect, reduce the cooperation difficulty or the card phenomenon that a teeth of a cogwheel 31 and a teeth of a cogwheel 41 appear when the meshing, the outer end through setting up the scraper blade 36 of motion is located inside the conveyer trough 32 all the time simultaneously, it stretches out to the conveyer trough 32 outside and leads to the interference that a teeth of a cogwheel 31 and a teeth of a cogwheel 41 produced when intermeshing to die with the card to reduce the scraper blade 36 outer end, thereby make a teeth of a cogwheel 31 and a teeth of a cogwheel 41 stabilize effectual cooperation, thereby further improvement the stability of storage case 1 when using.

During operation, at first, the material that will be used for printing is stored inside storage case 1, the material is filled inside the conveyer trough 32 of the one side of the top of action wheel 3 under the action of self gravity this moment, when needing to print the product, the controller drives the action wheel 3 of the other end of pivot 22 to rotate synchronously through the rotation of control motor 21, action wheel 3 can drive from the synchronous rotation of driving wheel 4 through the meshing of a number of teeth of a cogwheel 31 and a number two teeth of a cogwheel 41 when rotating this moment, action wheel 3 also can transport the conveyer trough 32 that the top was filled with the material to the position department that meshes with a number two teeth of a cogwheel 41 simultaneously, the inside material of this number two teeth of a cogwheel 41 outer end can mesh inside conveyer trough 32 notch and store inside this conveyer trough 32 in conveyer chamber 42 this moment, when this conveyer trough 32 moves to action wheel 3 bottom and is not meshing with a number two teeth of a cogwheel 41, the inside material of this moment filled in this conveyer trough 32 falls into on collecting chamber 11 lateral 37 into the interior of the feeding box 12, and then the material can flow into the interior of the feeding hose 13 and be ejected from the nozzle 15 by the air pressure in the inflation air pipe 14 for printing; at the moment, the conveying mechanism 2 is arranged in the storage box 1, so that the driving wheel 3 and the driven wheel 4 in the conveying mechanism 2 can uniformly convey materials in a rotating mode, and meanwhile, the material conveying speed can be effectively adjusted and controlled through the rotating speed of the rotating shaft 22, so that the printer can uniformly and efficiently print the products, the production quality of the printed products is greatly improved, and the service life of the printed products is greatly prolonged; simultaneously when the defeated material speed and the operating condition of needs to storage case 1 are adjusted, the user can send remote signal to the central processing unit who connects through bluetooth or wiFi this moment to make the user can long-rangely carry out high-efficient swift regulation and control to printing material conveying system, and then improved the remote monitoring and the operating capability of the 3D printing material conveying system of bluetooth or wiFi control.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
