Technical Field

[0001] This utility model relates to the field of 3D printing material premixing technology, specifically to a material premixing device for a 3D printing apparatus. Background Technology

[0002] Traditional material premixing devices on the market mix 3D printing materials by pouring all the raw materials into the device at once and feeding them in a stacked manner. This method fails to ensure that the various materials are mixed evenly, resulting in increased premixing time, low mixing efficiency, and poor mixing effect.

[0003] In the prior art, Chinese patent document CN221736720U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: A material premixing device for 3D printing, comprising: an annular seat. In this material premixing device for 3D printing, the material is continuously fed into the premixing cylinder while the premixing cylinder is rotating, which allows the material to be more evenly and comprehensively dispersed inside the premixing cylinder. At the same time, different materials fall together alternately, so that the material is mixed more evenly during feeding.

[0004] However, there are still situations where the equipment uses a lot of motors, which leads to high energy consumption and high maintenance costs in the later stages. Utility Model Content

[0005] The purpose of this invention is to provide a material premixing device for 3D printing apparatus to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A material premixing device for a 3D printing apparatus includes a premixing tank, a material guiding assembly inside the premixing tank, a stirring mechanism on the top of the premixing tank, and a transmission assembly on the surface of the premixing tank. The material guiding assembly and the transmission assembly each have four sets of components.

[0008] The transmission assembly includes a material conveying unit and a tapping unit. The tapping unit is disposed on the surface of the stirring mechanism and includes a mounting rod, a spring rod, and a tapping ball.

[0009] A further improvement of the present invention is that the premix tank includes a support frame, a premix main tank is fixedly installed in the middle of the support frame, and four sets of storage auxiliary tanks are fixedly installed inside the support frame near the surface of the premix main tank.

[0010] A further improvement of this utility model is that the material guiding assembly includes a support ring frame fixedly installed on the inner wall of the storage sub-tank. A material guiding pipe is fixedly installed on the surface of the support ring frame, and the bottom of the material guiding pipe is located inside the storage sub-tank. A discharge pipe is fixedly installed on the top of the material guiding pipe. By inserting the material guiding pipe into the storage sub-tank, the stored material can be discharged upward through the discharge pipe in conjunction with the transmission assembly.

[0011] A further improvement of this utility model is that the stirring mechanism includes a reduction motor fixedly installed in the middle of the top surface of the support frame. The output end of the reduction motor is rotatably mounted with a stirring frame. The stirring frame is slidably connected to the inner wall of the support frame through a bearing.

By installing the rotating gear on the stirring frame, the reduction motor for stirring can be used to drive the rotating gear to rotate, thereby driving the transmission component to operate and transport materials under meshing action, thus effectively saving the use of motor.

[0012] A further improvement of this utility model is that the material conveying unit includes a transmission gear disc that penetrates the top plate of the support frame. The surface of the transmission gear disc is slidably connected to the surface of the support frame. A material conveying screw is fixedly installed on the surface of the transmission gear disc. By setting the transmission gear disc to install the material conveying screw, it can be driven to rotate under the action of meshing with the rotating gear disc. This enables a single motor to drive multiple structures to operate, effectively reducing the use of motors.

[0013] A further improvement of this utility model is that: the top surface of the mounting rod is fixedly connected to the bottom surface of the rotating gear disk, one end of the spring rod is fixedly connected to the surface of the mounting rod, and the surface of the striking ball is fixedly connected to the spring end of the spring rod. By setting the striking unit, the mounting rod can be rotated while the rotating gear disk drives other components to operate, so that the striking ball, in conjunction with the spring rod, continuously strikes the discharge pipe, thereby promoting the flow of materials and preventing blockage.

[0014] A further improvement of this utility model is that the bottom heights of the four sets of discharge pipes are different, the transmission gear disc and the rotating gear disc are meshed and connected, and the bottom of the conveying screw is located inside the guide pipe. By using discharge pipes of different heights, the material in different storage tanks can be discharged at different positions, thereby achieving staggered mixing.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a material premixing device for a 3D printing apparatus. By installing a rotating toothed disc on the mixing rack, a geared motor for mixing can be used to drive the rotating toothed disc to rotate, thereby driving the transmission components to operate and transport materials under meshing action, thus effectively saving the use of motors.

[0017] 2. This utility model provides a material premixing device for a 3D printing apparatus. By installing a transmission gear plate for the feeding screw, the screw can be driven to rotate under the action of meshing with the rotating gear plate.

[0025] The present invention will be further described in detail below with reference to embodiments: Example

[0026] like Figure 1-5As shown, this utility model provides a material premixing device for a 3D printing apparatus, including a premixing tank 1. The premixing tank 1 includes a support frame 11, and a premixing main tank 12 is fixedly installed in the middle of the support frame 11. Four sets of material storage auxiliary tanks 13 are fixedly installed inside the support frame 11 near the surface of the premixing main tank 12. A material guiding component 2 is provided inside the premixing tank 1, a stirring mechanism 3 is provided on the top of the premixing tank 1, and a transmission component 4 is provided on the surface of the premixing tank 1. The material guiding component 2 and the transmission component 4 each have four sets of components. The transmission component 4 includes a material conveying unit and a tapping unit. The tapping unit is located on the surface of the stirring mechanism 3 and includes a mounting rod 43, a spring rod 44, and a tapping ball 45. By setting the tapping unit, the mounting rod 43 can be driven to rotate while the rotating toothed disc 33 drives other components to operate. This allows the tapping ball 45 to work with the spring rod 44 to continuously tap the discharge pipe 23, thereby promoting the flow of materials and preventing blockage. Example

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the material guiding component 2 includes a support ring frame 21 fixedly installed on the inner wall of the storage sub-tank 13, a material guiding pipe 22 fixedly installed on the surface of the support ring frame 21 and the bottom of the material guiding pipe 22 is located inside the storage sub-tank 13, and a discharge pipe 23 fixedly installed on the top of the material guiding pipe 22. The stirring mechanism 3 includes a reduction motor 31 fixedly installed in the middle of the top surface of the support frame 11, and a stirring frame 32 rotatably installed at the output end of the reduction motor 31. The stirring frame 32 is slidably connected to the inner wall of the support frame 11 through a bearing. A rotating gear disk 33 is fixedly installed on the central shaft surface of the stirring frame 32. By installing the rotating gear disk 33 on the stirring frame 32, the reduction motor 31 for stirring can be used to drive the rotating gear disk 33 to rotate, thereby driving the transmission component 4 to operate and transport materials under meshing action, thus effectively saving the use of motor. Example

[0028] like Figure 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the material conveying unit includes a transmission gear disc 41 that penetrates the top plate of the support frame 11. The surface of the transmission gear disc 41 is slidably connected to the surface of the support frame 11. A material conveying screw rod 42 is fixedly installed on the surface of the transmission gear disc 41. The top surface of the mounting rod 43 is fixedly connected to the bottom surface of the rotating gear disc 33. One end of the spring rod 44 is fixedly connected to the surface of the mounting rod 43. The surface of the striking ball 45 is fixedly connected to the spring end of the spring rod 44. The bottom heights of the four sets of discharge pipes 23 are different. The transmission gear disc 41 and the rotating gear disc 33 are meshed. The bottom of the material conveying screw rod 42 is located inside the guide pipe 22. By setting the transmission gear disc 41 to install the material conveying screw rod 42, it can be driven to rotate under the action of meshing with the rotating gear disc 33. Thus, a single motor can drive multiple structures to operate, effectively reducing the use of motors.

[0029] The following section will explain the working principle of the material premixing equipment used in 3D printing devices.

[0030] like Figure 1-5 As shown, when the material premixing equipment is in use, the materials are poured into the corresponding storage auxiliary tank 13, the reduction motor 31 is started to drive the stirring frame 32 to rotate, and at the same time the rotating toothed disc 33 rotates and drives the transmission toothed disc 41 to rotate under the meshing action, so that the conveying screw 42 can rotate in the guide pipe 22 and drive the material to move upward. Then the material can be introduced into the premixing main tank 12 through the discharge pipe 23, and then rotated and stirred by the stirring frame 32.

[0031] When the rotating toothed disc 33 rotates, the mounting rod 43 can rotate along with it, driving the spring rod 44 to strike the ball 45, which can then strike the discharge pipe 23, thereby preventing pipe blockage.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
