DETAILED DESCRIPTION
[0016] like Figure 1-4 As shown: A chopstick grinding machine includes a cart 1. The top rear side of the cart 1 is fixedly connected to two fixed seats 2 that are symmetrically distributed on the left and right. A support seat 3 is fixedly connected between the tops of the two fixed seats 2. The inner side wall of the support seat 3 is rotatably connected to a fixing ring 9 through a bearing 4. The front side wall of the fixing ring 9 is fixedly connected to a large gear 8. The front side wall of the large gear 8 is fixedly connected to an outer cylinder 10. The center of the inner wall of the rear side of the support seat 3 is fixedly connected to a fixed shaft 11. The fixed shaft 11 passes through the middle of the large gear 8. The fixed shaft 11 is rotatably connected to the large gear 8. The front end of the fixed shaft 11 is fixedly connected to a fixed gear 12. The fixed gear 1 2 has four moving gears 14 on the outside, which are located on the inside of the outer cylinder 10. The moving gears 14 are meshed with the fixed gear 12. The middle part of the rear side wall of the moving gear 14 is fixedly connected with a rotating shaft 13, which is rotatably connected to the large gear 8. The front side wall of the moving gear 14 is fixedly connected with a grinding cylinder 15, and a cylinder cover 16 is inserted into the inner wall of the front end of the grinding cylinder 15. The cylinder cover 16 slides with the grinding cylinder 15. The top of the support seat 3 is fixedly connected with a fixing frame 18, and the rear side wall of the fixing frame 18 is fixedly installed with a motor 19. The front end of the output shaft of the motor 19 is fixedly connected with a small gear 20, which meshes with the large gear 8.
[0017] The outer walls of the four grinding cylinders 15 are rotatably connected to the inner wall of the outer cylinder 10 through bearing three 17.
[0018] The top front side of the cart 1 is fixedly connected to two symmetrically distributed fixing seats 2 5, and a support ring 6 is fixedly connected between the tops of the two fixing seats 2 5. The inner side wall of the support ring 6 is rotatably connected to the outer cylinder 10 through the bearing 2 7.
[0019] First, the chopsticks to be polished are placed into each polishing cylinder 15 and covered with the cylinder cover 16. The sliding fit design of the cylinder cover 16 and the polishing cylinder 15 ensures the stable placement of the chopsticks and is convenient for taking and placing.
[0020] When the power is turned on and the motor 19 is started, the output shaft of the motor 19 drives the pinion 20 to start rotating.
[0021] The small gear 20 is meshed with the large gear 8 , so the rotation of the small gear 20 drives the large gear 8 and the outer cylinder 10 fixedly connected thereto to rotate synchronously. This rotation action causes the entire outer cylinder 10 and the four grinding cylinders 15 inside to revolve around the fixed axis 11 .
[0022] Due to the rotation of the large gear 8, the four movable gears 14 connected to it through the rotating shaft 13 also rotate accordingly. These movable gears 14 not only revolve with the large gear 8, but also rotate on their own through the meshing relationship with the fixed gear 12. This combined motion of revolution and rotation causes the chopsticks in each grinding cylinder 15 to continuously roll and rub against each other in the cylinder, thereby achieving an efficient and uniform grinding effect.
[0023] As the motor 19 continues to operate, the above-mentioned revolution and rotation process is repeated until the desired polishing effect is achieved. This utility model only protects the mechanical part, and the functions realized by the software control part are not within the scope of protection of this utility model.
