Detailed Embodiment

[0022] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] As Figures 1 - 3 shown, an embodiment of the present utility model provides a material adding device for a 3D printer, which includes a base 1, a material adding component, and several adding amount adjusting components: a fixing hole is provided in the middle of the base 1, and an adding funnel 2 is fixedly connected to the inner side of the fixing hole; the material adding component includes an annular adding cylinder 3 rotatably connected to the base 1 through a rotating disk. An inlet 13 is provided at the top of the annular adding cylinder 3, and a closing plug is provided at the inlet 13. The inner diameter size of the annular adding cylinder 3 is equal to the diameter size of the upper end of the adding funnel 2. An auxiliary material conveying bottom plate 11 is provided on the inner bottom surface of the annular adding cylinder 3. The cross section of the auxiliary material conveying bottom plate 11 is arranged in an inclined structure. Several material conveying ports 4 are provided on the inner side wall of the annular adding cylinder 3. A rotation driving component is provided on the base 1. The rotation driving component includes a rotation motor 8 fixedly connected to the lower part of the base 1. The output end of the rotation motor 8 penetrates the base 1 and is fixedly connected to a transmission gear 9. A transmission gear ring 10 is fixedly connected to the outer side wall of the annular adding cylinder 3, and the transmission gear ring 10 meshes with the transmission gear 9;

[0024] The rotation motor 8 drives the transmission gear 9 to rotate, and then drives the annular adding cylinder 3 to rotate through the meshing of the transmission gear 9 and the transmission gear ring 10. The material in the annular adding cylinder 3 leaks into the adding funnel 2 through the material conveying ports 4. Since the annular adding cylinder 3 is in a rotating state at this time, the material can be suspended and conveyed into the adding funnel 2 through the material conveying ports 4, so as to adjust the adding rate of the material by adjusting the rotation speed of the annular adding cylinder 3, avoid blockage of the adding funnel 2 caused by too fast material adding rate, and ensure the smoothness of the material adding for the 3D printer.

[0025] As Figures 1 - 3 shown, each adding amount adjusting component includes an adjusting plate 5 slidably connected to the material conveying port 4. The outer surface of the adjusting plate 5 is provided with a sealing coating, and the adjusting plate 5 is arranged in an arc structure. A support plate 6 is fixedly connected to the upper end of the adjusting plate 5. An adjusting screw 7 is threadedly connected through the middle of the support plate 6. The upper end of the adjusting screw 7 is fixedly connected to a knob 12, and the lower end of the adjusting screw 7 is rotatably connected to the top of the annular adding cylinder 3 through a bearing;

[0026] By rotating the knob 12 to drive the adjusting screw 7 to rotate, the support plate 6 threadedly connected to the adjusting screw 7 starts to move up and down, so that the support plate 6 drives the adjusting plate 5 to move up and down relative to the annular adding cylinder 3 at the material conveying port 4, so as to adjust the conveying space size of the material conveying port 4, thereby enabling free adjustment of the adding amount of the material, avoiding material waste, and facilitating subsequent printing operations.

[0027] The detailed working process of the present utility model is as follows:

[0028] 1. When in use, with the material inlet 4 closed, materials are fed into the annular addition cylinder 3 through the feed inlet 13. When the 3D printer needs to add materials, open the material inlet 4 and start the rotary motor 8. Drive the transmission gear 9 to rotate through the rotary motor 8, and then drive the annular addition cylinder 3 to rotate through the meshing of the transmission gear 9 and the transmission ring gear 10. The materials in the annular addition cylinder 3 leak into the addition funnel 2 through the material inlet 4. Since the annular addition cylinder 3 is in a rotating state at this time, the materials can be suspended and conveyed to the addition funnel 2 through the material inlet 4, so as to adjust the addition rate of the materials by adjusting the rotation speed of the annular addition cylinder 3, avoid blockage of the addition funnel 2 caused by too fast material addition rate, and ensure the smoothness of material addition for the 3D printer.

[0029] 2. If it is necessary to adjust the material addition amount according to the size of the object printed by the 3D printer, the adjusting screw 7 can be driven to rotate by turning the knob 12, so that the support plate 6 threadedly connected to the adjusting screw 7 starts to move up and down, and the support plate 6 drives the adjusting plate 5 to move up and down relative to the annular addition cylinder 3 at the material inlet 4, so as to adjust the conveying space size of the material inlet 4, thereby enabling free adjustment of the material addition amount, avoiding material waste, and facilitating subsequent printing operations.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
