Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D printing granular material barrel. Background Art

[0002] At present, the pellet material 3D printer molding technology on the market is becoming more and more perfect, and the market demand for it is also showing a significant growth trend. However, traditional pellet material containers have exposed some problems during use, especially when the air compressor port is directly inserted into the container, it is easy to break the material during the printing process; this problem of breaking the material is usually caused by the inability to ensure the negative pressure balance and stability in the air compressor port; if the air compressor port is inserted too deep, it will be blocked due to poor air circulation, thus causing the material to break; and if the air compressor port is inserted too shallowly, during the continuous suction process, the lack of sufficient pellet material supply near the air compressor port will also cause the material to break.

[0003] Moreover, conventional granular material containers generally lack a drying function and cannot ensure that the temperature and humidity of the granular material in the container reach the standard state; such fluctuations in temperature and humidity will directly affect the basic properties of the material, and thus affect the printing quality and product stability; the above defects are problems that need to be urgently solved by technical personnel in this field. Utility Model Content

[0007] Preferably, the guide mechanism is an inclined mesh guide plate, and an opening corresponding to the suction box is provided on the wall of the storage barrel corresponding to the lower end of the mesh guide plate; an electric heating blower is installed below the mesh guide plate corresponding to the storage barrel, and an air inlet is provided at the bottom of the storage barrel.

[0008] Preferably, the guide mechanism is an inclined guide plate, and a transition slot box is provided at the lower end of the guide plate, one side of which is connected to the suction box. An electric blower for blowing hot air into the transition slot box is installed on the side of the transition slot box away from the suction box, and an isolation net is provided at the air outlet of the electric blower.

[0009] Preferably, a limiting frame with a hollow structure is provided on the inner wall of the suction box corresponding to the position of its feed inlet.

[0014] The utility model discloses a 3D printing granular material barrel with a simple structure and convenient use. When in use, a negative pressure suction pipe can be inserted into a suction box to perform negative pressure suction. As the 3D printing granular material in the suction box is continuously sucked away, the 3D printing granular material in the storage barrel flows into the suction box along a guide mechanism under the action of its own gravity for replenishment. This solves the problem in the prior art that the negative pressure suction pipe is directly inserted into the barrel, and the negative pressure balance in the negative pressure suction pipe cannot be guaranteed, which easily leads to material breakage.
