Technical Field
[0001] This utility model relates to the field of 3D printing consumables technology, and more specifically, to a raw material premixing device for 3D printing. Background Technology
[0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology. It uses a premixing device for 3D printing materials to construct objects by printing layer by layer based on digital model files and using powdered metal or plastic and other bondable materials. During the production process, the consumables for 3D printing need to be mixed by a premixing device to facilitate subsequent processing.
[0003] Based on the above, the inventors have found that existing premixing devices have simple structures and single functions, mainly for premixing and stirring. However, during the stirring process, due to the different particle sizes of different raw materials, the premixing effect is poor. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a raw material premixing device for 3D printing, in order to achieve a more practical purpose.

[0016] 3. Beneficial Effects
[0017] Compared with existing technologies, the advantages of this utility model are:

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1-4 A premixing device for raw materials used in 3D printing includes a premixing tank 1, a feeding valve 2 fixedly connected to one side of the premixing tank 1, a discharging valve 3 fixedly connected to the bottom of the premixing tank 1, a drive motor 4 and a cylinder 5 fixedly connected to the top of the premixing tank 1, a crushing mechanism 6 centrally located inside the premixing tank 1, a guide rod 7 fixedly connected to the output end of the drive motor 4, a stirring roller 8 sleeved on the lower end of the guide rod 7, a connecting sleeve 9 fixedly connected to the top of the stirring roller 8, and a limit ring 10 fixedly connected to the output end of the cylinder 5.
[0028] The crushing mechanism 6 includes a filter plate 13, and a set of crushing rollers 14 and a set of push plates 15 are provided on the top surface of the filter plate 13. The crushing mechanism 6 is provided in order to screen and filter the raw materials and crush the unqualified raw materials.
[0029] See Figure 3 A sliding block is fixedly connected to the bottom end of the guide rod 7, and the stirring roller 8 is slidably connected to the sliding block. The guide rod 7 drives the stirring roller 8 to rotate synchronously through the sliding block to stir the raw materials.
[0030] See Figure 2 The limiting ring 10 is located outside the connecting sleeve 9, and the limiting ring 10 is movably connected to the connecting sleeve 9. The starting cylinder 5 drives the limiting ring 10 to move up and down, and the limiting ring 10, in conjunction with the connecting sleeve 9, drives the stirring roller 8 to move, thereby adjusting the stirring position.
[0031] See Figure 3Guide rods 11 are fixedly connected to both sides of the limiting ring 10. A guide cylinder 12 is fixedly connected to the upper end of the guide rod 11, and the top of the guide cylinder 12 is fixedly connected to the premixing tank 1. The limiting ring 10 works in conjunction with the guide rods 11 to ensure the stability of the movement of the limiting ring 10.
[0032] See Figure 2 The filter plate 13 is located in the center inside the premixing tank 1 and is fixedly connected to the premixing tank 1. The raw material enters the premixing tank 1 through the feed valve 2 and is filtered by the filter plate 13.
[0033] See Figure 2 The stirring roller 8 passes through the middle of the filter plate 13 and is movably connected to the filter plate 13. Raw materials that do not meet the requirements remain on the top surface of the filter plate 13.
[0034] See Figure 4 The crushing roller 14 and the push plate 15 are staggered, and the top of the crushing roller 14 and the top of the push plate 15 are fixedly connected to the stirring roller 8. The rotation of the stirring roller 8 drives the crushing roller 14 and the push plate 15 to rotate synchronously. The crushing roller 14 crushes the raw material on the top surface of the filter plate 13, and then pushes it down to the bottom of the premixing tank 1 by the push plate 15 for premixing.
[0035] In use: Raw materials are fed into the premixing tank 1 through the feed valve 2 and filtered through the filter plate 13. The drive motor 4 is started, causing the guide rod 7 to drive the stirring roller 8 to rotate for premixing. The rotation of the stirring roller 8 also drives the crushing roller 14 and the push plate 15 to rotate synchronously. The crushing roller 14 crushes the raw materials on the top surface of the filter plate 13. Then, the push plate 15 pushes the raw materials to fall to the bottom of the premixing tank 1 for premixing. During the mixing process, the cylinder 5 is started to drive the limit ring 10 to move up and down. The limit ring 10, in conjunction with the connecting sleeve 9, drives the stirring roller 8 to move. The limit ring 10, in conjunction with the guide rod 11, ensures the stability of the movement of the limit ring 10 and adjusts the mixing position, thereby expanding the mixing range and improving the premixing effect of the raw materials. Finally, the mixed raw materials are discharged through the discharge valve 3.
