When using the grinding machine, the raw material is placed on the top of the placing rod, the motor 3 drives the first gear 4 and the round plate 10 to rotate. Since the first gear 4 and the second gear 6 are meshed with each other, the four shafts are driven to rotate simultaneously, and then the grinding blocks 7 are pressed against the top of the raw material by the cylinder 2, so that the grinding efficiency of the lens can be increased to a certain extent.

[0028] Refer to Figure 2 and Figure 3, the limiting device 8, the rubber ring 802. A circular groove 801 is provided at the top of the placing rod. The top of the circular groove 801 is fixedly connected to the rubber ring 802. The inner wall of the circular groove 801 is fixedly connected to a support rod 803. The top of the support rod 803 is fixedly connected to a suction cup 804. When using the limiting device 8, place the raw material on the top of the rubber ring 802 fixed to the top of the circular groove 801, thereby increasing the friction between the raw material and the placing rod to a certain extent. Then, squeeze the raw material, so that the suction cup 804 adsorbs on the bottom of the raw material. In this way, the raw material can be well restricted on the top of the placing rod, thereby avoiding the movement of the raw material during grinding to a certain extent. The bottom of the circular plate 10 is fixedly connected to a damping rod 810. A first spring 811 is sleeved on the surface of the damping rod 810. The top of the first spring 811 is fixedly connected to the top of the circular plate 10. One end of the first spring 811 close to the damping rod 810 is fixedly connected to the bottom of the damping rod 810. When the circular plate 10 approaches the connecting cylinder 11, the bottom of the damping rod 810 presses on the middle of the raw material, which can squeeze the raw material on the top of the placing rod to a certain extent. A connecting groove 805 is provided on the inner wall of the support rod 803. A rubber plug 806 is provided at the top of the connecting groove 805.

The end of the first connecting rope 808 far from the connecting cylinder 11 is fixedly connected to a clamping block 809. Manually pull the first connecting rope 808 through the clamping block 809 to compress the second spring 807, so that the rubber plug 806 is away from the bottom of the suction cup 804. This can facilitate the suction cup 804 to adsorb on the bottom of the raw material and also facilitate the suction cup 804 to move away from the bottom of the raw material. The bottom of the damping rod 810 is fixedly connected to a circular block 812. A positioning groove 813 is provided at the bottom of the circular block 812. A ball 814 is provided on the inner wall of the positioning groove 813. When the damping rod 810 presses on the top of the raw material and the circular plate 10 is driven to rotate, the ball 814 rotates well on the top of the raw material, which can avoid the damping rod 810 affecting the rotation of the circular plate 10 to a certain extent.

[0029] Refer to Figure 4, the mobile device 9 includes a fixed frame 901, the fixed frame 901 is fixedly connected to the inner wall of the connecting cylinder 11 evenly. Round rods 902 are fixedly connected to the inner walls of the fixed frame 901. Rectangular strips 903 are rotatably sleeved on the surfaces of the round rods 902. A third spring 907 is fixedly connected to one side of the rectangular strip 903. The end of the third spring 907 away from the rectangular strip 903 is fixedly connected to the inner wall of the connecting cylinder 11. A second connecting rope 908 is fixedly connected to one side of the rectangular strip 903. The second connecting rope 908 slidably penetrates and is inserted into one side of the connecting cylinder 11. When using the mobile device 9, place the raw materials on the tops of the plurality of rectangular strips 903, and then manually pull the second connecting rope 908 in the direction away from the connecting cylinder 11, so that the third spring 907 contracts, which can, to a certain extent, make the raw materials placed in the middle of the top of the placing rod. The end of the second connecting rope 908 away from the connecting cylinder 11 is fixedly connected to a ring 909. The ring 909 is slidably sleeved on the surface of the connecting cylinder 11. A rubber conical ring 911 is arranged at the bottom of the connecting cylinder 11. The rubber conical ring 911 is fixedly connected to the surface of the connecting cylinder 11. Manually control the ring 909 to move downward on the surface of the connecting cylinder 11, which can well control the second connecting rope 908 to move outward at the same time. Manually slide the ring 909 and squeeze the ring 909 to the bottom of the rubber conical ring 911, which can make the rectangular strip 903 closely adhere to the inner wall of the connecting cylinder 11, thereby avoiding the rectangular strip 903 from affecting the grinding of the raw materials. Grooves 904 are evenly opened on the side of the rectangular strip 903 away from the second connecting rope 908. Connecting rods 905 are fixedly connected to the inner walls of the grooves 904. Rolling cylinders 906 are rotatably sleeved on the surfaces of the connecting rods 905. When the raw materials move on the rectangular strip 903, the rolling cylinders 906 are driven to rotate on the surfaces of the connecting rods 905, which can make the raw materials move well on the surface of the rectangular strip 903. A limiting groove 910 is opened on one side of the support frame 1. The inner wall of the limiting groove 910 is slidably connected to the ring 909. A positioning rod 912 slidably penetrates and is inserted into one side of the ring 909. A fourth spring 913 is sleeved on the surface of the positioning rod 912. One end of the fourth spring 913 is fixedly connected to the bottom of the inner wall of the support frame 1. The end of the fourth spring 913 close to the positioning rod 912 is fixedly connected to the bottom of the ring 909. By squeezing the ring 909 in the direction close to the support frame 1 through the fourth spring 913, the ring 909 can be made to return to its original position.

[0030] Working principle: When using the grinding machine, place the raw material on the top of the placing rod. Drive the first gear 4 and the circular plate 10 to rotate through the motor 3. Since the first gear 4 and the second gear 6 mesh with each other, four shafts are driven to rotate simultaneously. Then, use the cylinder 2 to press the grinding block 7 against the top of the raw material, which can, to a certain extent, improve the grinding efficiency of the lens. When using the limiting device 8, place the raw material on the top of the rubber ring 802 fixed on the top of the circular groove 801, which can, to a certain extent, increase the friction between the raw material and the placing rod. Then, when the circular plate 10 approaches the connecting cylinder 11, the bottom of the damping rod 810 presses against the middle of the raw material. When the damping rod 810 presses against the top of the raw material and the circular plate 10 is driven to rotate, the ball 814 rotates well on the top of the raw material, which can, to a certain extent, prevent the damping rod 810 from affecting the rotation of the circular plate 10. This can, to a certain extent, press the raw material against the top of the placing rod, and then the suction cup 804 adsorbs to the bottom of the raw material, which can well limit the raw material on the top of the placing rod and, to a certain extent, prevent the raw material from moving during grinding. Manually pull the first connecting rope 808 through the clamping block 809, which compresses the second spring 807, so that the rubber plug 806 moves away from the bottom of the suction cup 804, which is convenient for the suction cup 804 to adsorb to the bottom of the raw material and also convenient for the suction cup 804 to move away from the bottom of the raw material. When using the moving device 9, place the raw material on the top of the multiple rectangular strips 903. Manually control the ring 909 to move downward on the surface of the connecting cylinder 11, which can well control the second connecting rope 908 to move outward simultaneously, and then the third spring 907 contracts. Manually slide the ring 909 and press the ring 909 against the bottom of the rubber conical ring 911, which can make the rectangular strips 903 closely adhere to the inner wall of the connecting cylinder 11, thus preventing the rectangular strips 903 from affecting the grinding of the raw material. This can, to a certain extent, place the raw material in the middle of the top of the placing rod.

[0031] It should be noted that all damping rods in this case are telescopic dampers that can absorb energy during the telescopic process.
