[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-2 , a 3D printer material tray structure, including a mounting frame 1, an outer wall of the mounting frame 1 is provided with a bearing 8, the outer wall of the bearing 8 is fixedly connected to a rotating cylinder 2, the outer wall of the rotating cylinder 2 is penetrated with a sliding hole 3, a plurality of sliding holes 3 are provided, and the plurality of sliding holes 3 are distributed in a circular array on the outer wall of the rotating cylinder 2, the rotating cylinder 2 is slidably connected with a sliding column 4 through the plurality of sliding holes 3, the number of sliding columns 4 corresponds to the number of sliding holes 3, the tops of the plurality of sliding columns 4 are fixedly connected with a resistance block 6, one end of the resistance block 6 is provided with an arc, the top of the arc is higher than the outer wall of the resistance block 6, so that when the plurality of resistance blocks 6 are distributed in a circular array along the circumference of the rotating cylinder 2, the ends of the plurality of resistance blocks 6 with the arc are surrounded into a circle, the outer walls of the plurality of sliding columns 4 are wound with a return spring 5, and one end of the plurality of resistance blocks 6 is fixedly connected with a blocking block 7;

[0023] During use, since the central part of the material tray is generally in the shape of a circular hole and of different sizes, the staff can compress the multiple resistance blocks 6 toward the central part of the rotating drum 2, so that material trays of different sizes can pass through the curved end of the multiple resistance blocks 6. Further, the multiple resistance blocks 6 are loosened and moved away from the rotating drum 2 under the action of the multiple return springs 5, so that the top outer walls of the multiple resistance blocks 6 are in contact with the inner wall of the material tray, thereby fixing the material tray.

[0024] Reference Figure 3 The outer walls of the multiple blocking blocks 7 are fixedly connected with adjustment columns 9, and the outer wall of the mounting frame 1 is rotatably connected with a limiting plate 10. The outer wall of the limiting plate 10 is penetrated by a limiting groove 11. The number of the limiting grooves 11 is equal to the number of the adjusting columns 9, and the outer walls of the multiple adjusting columns 9 are respectively adapted to the inner walls of the multiple limiting grooves 11. The user can adjust the height of the multiple interference blocks 6 through the multiple adjusting columns 9, thereby facilitating the installation of material trays of different sizes.

[0025] Reference Figure 3The outer wall of the mounting frame 1 is rotatably connected with an adjusting disk 12, and the adjusting disk 12 is located on the side of the limit plate 10 away from the conflicting block 6. The outer wall of the adjusting disk 12 is penetrated by an adjusting arc groove 13. The number of adjusting arc grooves 13 is the same as the number of adjusting columns 9, and the inner walls of the plurality of adjusting arc grooves 13 are respectively adapted to the outer walls of the plurality of adjusting columns 9, and the plurality of adjusting arc grooves 13 are all provided with curvatures. When the operator needs to adjust the positions of the plurality of conflicting blocks 6, the adjusting disk 12 can be rotated. Since the plurality of adjusting columns 9 are respectively located inside the plurality of adjusting arc grooves 13, and the plurality of adjusting arc grooves 13 have curvatures, as the adjusting disk 12 rotates, the plurality of adjusting columns 9 move along the adjusting arc grooves 13 and gradually approach the center part of the adjusting disk 12, thereby driving the plurality of conflicting blocks 6 to approach the center part of the rotating cylinder 2, thereby achieving the effect of adjusting the plurality of conflicting blocks 6.

[0026] Reference Figure 4 The outer wall of the mounting frame 1 is penetrated with a receiving groove 14, and the receiving groove 14 is located in the center of the rotating cylinder 2. The outer wall of the mounting frame 1 is provided with a slide groove 15, and the slide groove 15 is located in the center of the rotating cylinder 2, and there are two of them. The mounting frame 1 is slidably connected with an extrusion block 16 through the two slide grooves 15. The two extrusion blocks 16 are both semi-cylindrical. When the flat surfaces of the two extrusion blocks 16 are close to each other, they are combined into a cylindrical shape, and the diameter of the cylinder is the same as the inner diameter of the receiving groove 14. When it is necessary to fix the position of the rotating cylinder 2, the operator can pull the extrusion block 16 out of the receiving groove 14, and further separate the extrusion block 16, so that the outer walls of the two extrusion blocks 16 are respectively fitted with the inner wall of the rotating cylinder 2, thereby reducing the rotation speed of the rotating cylinder 2, and under the action of friction, until the rotating cylinder 2 stops and the position is fixed.

[0027] Reference Figure 4 The inner walls of the two extrusion blocks 16 are fixedly connected with springs 17. When the two extrusion blocks 16 are separated, they move toward the inner walls of the rotating cylinder 2 under the action of the two springs 17 until the outer walls of the two extrusion blocks 16 collide with the inner wall of the rotating cylinder 2. The two springs 17 provide force for the two extrusion blocks 16, thereby limiting the position of the rotating cylinder 2, making it convenient for the staff to effectively adjust the position of multiple conflicting blocks 6 when rotating the adjustment disk 12.

[0028] Reference Figure 4 A telescopic connecting rod 18 is fixedly connected to the outer side walls of the two extrusion blocks 16, and the two ends of the telescopic connecting rod 18 are respectively located on the outer side walls of the two extrusion blocks 16. When the two extrusion blocks 16 are separated, the telescopic connecting rod 18 is gradually extended under the action of the two extrusion blocks 16. Since the telescopic connecting rod 18 is located outside the two extrusion blocks 16, the staff can pull the telescopic connecting rod 18 to adjust the position of the two extrusion blocks 16.

[0029] Working principle:

[0030] When in use, the two squeezing blocks 16 are pulled out by the telescopic connecting rod 18. Under the action of the two springs 17, the outer side walls of the two squeezing blocks 16 respectively contact and squeeze the inner side walls of the rotating cylinder 2, so that the position of the rotating cylinder 2 is fixed under the action of friction. The adjusting disk 12 is rotated. Since the plurality of adjusting columns 9 are respectively located inside the plurality of adjusting arc grooves 13, and the plurality of adjusting arc grooves 13 have curvatures, as the adjusting disk 12 rotates, the plurality of adjusting columns 9 move along the adjusting arc grooves 13 and gradually approach the center of the adjusting disk 12, thereby driving the plurality of adjusting columns 9 to move. The multiple resistance blocks 6 are moved toward the center of the rotating cylinder 2, thereby achieving the effect of adjusting the multiple resistance blocks 6. At this time, since the center of the material tray is generally in the shape of a circular hole and of different sizes, when in use, the staff can compress the multiple resistance blocks 6 toward the center of the rotating cylinder 2, so that material trays of different sizes can all pass through the curved end of the multiple resistance blocks 6. Further, the multiple resistance blocks 6 are loosened and moved away from the rotating cylinder 2 under the action of the multiple return springs 5, so that the top outer walls of the multiple resistance blocks 6 are in contact with the inner wall of the material tray, thereby fixing the material tray.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
