Description

Technical Field

[0001] The utility model relates to the field of 3D printers, in particular to a 3D printer feeding box. Background Art

[0002] 3D printers, also known as three-dimensional printers, are a type of rapid prototyping equipment. There are two common types of 3D printers: desktop 3D printers and light-curing 3D printers. When using a light-curing 3D printer, resin consumables are used. Most existing light-curing 3D printers are generally equipped with a feed box for holding resin consumables to feed the light-curing 3D printer.

[0003] There are many types and colors of resin consumables for light-curing 3D printers. When using a light-curing 3D printer, the resin consumables are generally replaced according to the requirements of the printed object. If multiple objects need to be printed continuously and the required resin consumables are different, it will take a lot of time to replace the consumables. Utility Model Content

The upper end of the column is slidably connected to the hexagonal top frame. A second spring is fixed to the lower end of the hexagonal top frame, and the lower end of the second spring is fixed to the column.

[0008] Preferably, the plane of the outer ring of the hexagonal plate corresponds to the angle of the inner wall of the hexagonal ring, and the angle at the bent portion of the bent plate is the same as the angle between two adjacent end faces of the inner wall of the hexagonal ring.

[0009] Preferably, a groove is provided at the upper end of the bearing seat, and a rubber layer is provided on the inner wall of the groove of the bearing seat.

[0010] Preferably, a front cover is installed at the front end of the box body, a transparent glass plate is fixed in the middle of the front cover, and an embedded handle is installed on the front end surface of the front cover.

[0027] The feeding mechanism includes a hexagonal ring 2, which is fixed to the bottom of the box body 1. A rotating frame 21 is provided in the middle of the hexagonal ring 2, and the rotating frame 21 is rotatably connected to the box body 1. A hexagonal plate 22 is fixed to the upper end of the rotating frame 21. The six end faces of the hexagonal plate 22 are fixed with telescopic rods 23. The telescopic end of the telescopic rod 23 is fixed with a bending plate 24. The plane of the outer ring of the hexagonal plate 22 corresponds to the angle of the inner wall of the hexagonal ring 2, and the angle at the bending point of the bending plate 24 is the same as the angle of the two adjacent end faces of the inner wall of the hexagonal ring 2. The outer ring of the telescopic rod 23 is provided with a first spring 25, and an electric push rod 26 is installed inside the hexagonal plate 22. The telescopic end of the electric push rod 26 is fixed with a hexagonal base frame 27. A bearing seat 28 is fixed at each angle of the outer ring of the hexagonal base frame 27. A groove is provided on the upper end of the bearing seat 28, and a rubber layer is provided on the inner wall of the groove of the bearing seat 28. A supporting mechanism is placed on the upper end of the bearing seat 28. The material storage barrel 3 is provided on the upper end of each supporting seat 28. The outer wall of the material storage barrel 3 is provided with a labeling groove 31. The upper end of the material storage barrel 3 is fixed with a feeding port 32. A column 29 is fixed in the middle of the upper end of the hexagonal bottom frame 27. The upper end of the column 29 is slidably connected to the hexagonal top frame 210. The lower end of the hexagonal top frame 210 is fixed with a second spring 211, and the lower end of the second spring 211 is fixed to the column 29. The upper end of the hexagonal top frame 210 is fixed with a second spring 211. The lower end of the second spring 211 is fixed to the column 29. A through hole 212 is provided at the end corresponding to the feed port 32 at the upper end of each storage barrel 3, and a threaded tube 33 is threadedly connected to the upper end of the box body 1. An insertion block 34 is fixed to the lower end of the threaded tube 33, and the outer ring of the insertion block 34 is provided with a rubber layer, and the outer ring size of the insertion block 34 corresponds to the inner ring size of the feed port 32; the threaded tube 33 is threadedly connected to the box body 1, and when the threaded tube 33 is rotated, the threaded tube 33 and the insertion block 34 can be lowered.

[0028] Working principle: Before using the device, first open the front cover 11, then remove all the storage barrels 3 and load different resin consumables into them. After loading, label the corresponding resin consumable name on the labeling groove 31 on the outer wall of each storage barrel 3. Finally, install the storage barrel 3 on the supporting seat 28. After the preparation is completed, start the electric push rod 26 to drive the hexagonal bottom frame 27 to rise. At this time, the rising hexagonal bottom frame 27 and the column 29 will drive the hexagonal top frame 210 to rise, so that the feeding port 32 at the upper end of the storage barrel 3 extends into the The through hole 212 is formed, and then the hexagonal top frame 210 will support the inner wall of the upper end of the box body 1. At this time, the sliding connection between the column 29 and the hexagonal top frame 210 is formed. As the second spring 211 continues to rise, it will be compressed. After the second spring 211 is fully compressed, the threaded tube 33 is rotated to make the threaded tube 33 drive the insertion block 34 to descend. Then, the insertion block 34 can be pushed into the feed port 32 of the storage barrel 3 below it. During operation, the extraction tube of the light-curing 3D printer is inserted into the storage barrel 3 at the lower end through the threaded tube 33. In this way, the material can be fed to the operation of the light-curing 3D printer. When the next object to be printed by the light-curing 3D printer needs to be replaced with other resin consumables, the threaded tube 33 is first rotated in the opposite direction to make the insertion block 34 disengage from the storage barrel 3 at its lower end. Then the electric push rod 26 drives the hexagonal base 27 to reset. Finally, the rotating rack 21 is connected to the box body 1 by rotation, and the rotating rack 21 is rotated sixty degrees or multiples of sixty degrees so that the storage barrel 3 containing the required consumables is located directly below the threaded tube 33. In this way, the material can be fed to the operation of the light-curing 3D printer. When the next object to be printed by the light-curing 3D printer needs to be replaced with other resin consumables, the threaded tube 33 is first rotated in the opposite direction to make the insertion block 34 disengage from the storage barrel 3 at its lower end. Then, the electric push rod 26 drives the hexagonal base 27 to reset. Finally, the rotating rack 21 is connected to the box body 1 by rotation, and the rotating rack 21 is rotated sixty degrees or multiples of sixty degrees so that the storage barrel 3 containing the required consumables is located directly below the threaded tube 33. The resin consumables can be replaced by unloading, thereby making the use of the light-curing 3D printer more convenient. In addition, due to the elasticity of the first spring 25 and the angle at the bending point of the bending plate 24 being the same as the angle between the two adjacent end faces of the inner wall of the hexagonal ring 2, when the rotating frame 21 rotates sixty degrees, the telescopic rod 23 and the first spring 25 will drive the bending plate 24 to hit the angle of the inner wall of the hexagonal ring 2, so that the rotation of the rotating frame 21 will produce a certain sense of frustration, thereby facilitating the determination of the rotation angle of the rotating frame 21 when the resin consumables are replaced.
