[0019] 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.

[0020] A centrifugal grinding machine, such as Figure 1 and 2As shown, it includes a frame 1, a horizontally arranged connecting tube 2, and a feeding hopper 3 connected thereto, the connecting tube 2 is fixedly connected to the frame 1, one end of the connecting tube 2 is closed and the other end is open, a guide plate 5 arranged obliquely is fixedly connected to the frame 1, a baffle is located below the open end of the connecting tube 2, the open end of the connecting tube 2 can be opened and closed, a connecting flange is fixedly connected to the outer ring of the open end of the connecting tube 2, the connecting flange is connected to a sealing plate 4 through bolts and nuts, and the sealing plate 4 seals the open end of the connecting tube 2.

[0021] A rotatable swivel assembly is arranged in the connecting tube 2, and the swivel assembly divides the connecting tube 2 into a plurality of rotatable separation spaces, and the separation spaces are used for placing abrasives and ear tubes.

[0022] The rotary assembly includes a connecting shaft 15 which is coaxially rotatable with the connecting cylinder 2, and a plurality of rotating plates 16 which are fixedly connected to the outer ring of the connecting shaft 15. A separation space is formed between adjacent rotating plates 16, and a gap exists between the rotating plates 16 and the inner wall of the connecting cylinder 2. One end of the connecting shaft 15 is coaxially fixedly connected with a rotating shaft 13 which passes through the closed end of the connecting cylinder 2. A driving motor 6 is fixedly connected to the frame 1. The driving motor 6 and the rotating shaft 13 are connected through a transmission assembly. The transmission assembly includes a rotating shaft 2 9 which is rotatably connected to the frame 1, a driving wheel 1 7 which is fixedly connected to the output shaft of the driving motor 6, a driven wheel 10 and a driving wheel 2 11 which are fixedly connected to the rotating shaft 2 9, and a driven wheel 2 14 which is fixedly connected to the rotating shaft 13. The driving wheel 1 7 and the driven wheel 10 are connected through a transmission belt 1 8, and the driving wheel 2 11 and the driven wheel 2 14 are connected through a transmission belt 2 12.

[0023] When the ear tube needs to be polished, the operator only needs to manually extend the ear tube into the open end of the connecting tube 2. Specifically, the ear tube will enter the separation space between the adjacent rotating plates 16. After the ear tube is placed, the sealing plate 4 is connected to the connecting flange by bolts and nuts to complete the sealing of the open end of the connecting tube 2. Then, the abrasive is put into the connecting tube 2 through the feeding hopper 3, so that the space in the connecting tube 2 is filled with the abrasive. Then the driving motor 6 is started, and the driving motor 6 controls the output shaft to rotate slowly. The output shaft of the driving motor 6 drives the driving wheel 7 to rotate, and the driven wheel 10 on the rotating shaft 9 is adjusted to rotate through the transmission belt 8. When the rotating shaft 9 rotates, it will drive the driving wheel 2 11 to rotate, and the driving wheel 2 11 will rotate through the transmission belt 2 12 is transmitted to the driven wheel 2 14. Once the driven wheel 2 14 rotates, it will drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it will drive the connecting shaft 15 to rotate coaxially. During the rotation, several rotating plates 16 rotate together, so that the ear tube and the abrasive in the separation space are centrifugally rotated together. The abrasive can polish and grind the surface of the ear tube during the rotation. After the polishing and grinding is completed, the driving motor 6 is stopped, and then the structure of the bolt and nut is cancelled, so that the connecting tube 2 is opened, the ear tube is taken out of the separation space, and the abrasive is allowed to flow out of the connecting tube 2. The outflow of the abrasive is guided by the guide plate 5 to complete the recovery of the abrasive. In this way, the polishing and grinding of the ear tube can be completed. At the same time, the structure of the centrifugal grinder is simple, and when the ear tube needs to be polished and ground, the work can be completed relatively simply.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
