Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a ball mill that prevents aluminum silver paste leakage, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a cylinder 1, a discharge pipe 2 is fixedly connected to the side surface of the cylinder 1, a connecting plate 3 is fixedly connected to the side surface of the discharge pipe 2, a sealing cover 4 is movably connected to one side of the connecting plate 3, a groove 7 is provided on the side of the connecting plate 3 near the sealing cover 4, an ejection groove 8 is provided inside the connecting plate 3 and communicates with the groove 7, and an ejection mechanism is provided on the connecting plate 3.

[0019] The ejection mechanism includes an ejector block 9, the side surface of which slides against the inner wall of the ejection groove 8, a connecting rod 10 is fixedly connected to one side of the ejector block 9, the connecting rod 10 extends to the outside of the connecting plate 3, a spring 11 is sleeved on the side surface of the connecting rod 10, and a limit block 12 is fixedly connected to the side surface of the connecting rod 10.

[0020] The end of the discharge pipe 2 away from the cylinder 1 is flush with one side of the connecting plate 3. A rubber gasket 5 is provided inside the sealing cover 4, and a sealing ring 6 is provided inside the groove 7. One side of the sealing ring 6 is in contact with one side of the rubber gasket 5.

[0021] The side of the top block 9 away from the connecting rod 10 is in contact with the side of the sealing ring 6 away from the rubber pad 5. One end of the spring 11 is fixedly connected to the side of the connecting plate 3 away from the sealing cover 4, and the other end of the spring 11 is fixedly connected to one side of the limiting block 12.

[0022] The cylinder 1 is part of the main body of the ball mill. During use, the sealing cover 4 needs to be fastened to the connecting plate 3. The rubber gasket 5 and the sealing ring 6 increase the sealing between the sealing cover 4 and the connecting plate 3, effectively reducing the possibility of aluminum silver paste leakage during ball mill operation. When the operator replaces the sealing ring 6, they can press the connecting rod 10. The connecting rod 10 can drive the top block 9 to slide in the ejection groove 8. During the sliding process, the top block 9 can push the sealing ring 6 out of the groove 7, which makes it convenient for the operator to replace the sealing ring 6. In addition, when the connecting rod 10 moves, the limiting block 12 will also move synchronously. When the limiting block 12 moves, it can compress the spring 11. After the operator releases the connecting rod 10, the spring 11 will release the pressure and drive the top block 9 of the connecting rod 10 to reset.

[0023] In order to facilitate the staff to press the connecting rod 10, such as Figure 3 , Figure 4 and Figure 5 As shown, a bracket 13 is fixedly connected to the side surface of the discharge pipe 2, and a ring plate 14 is sleeved on the side surface of the discharge pipe 2. The connecting rod 10 passes through the ring plate 14, and one side of the ring plate 14 is in contact with the side of the limiting block 12 away from the spring 11.

[0024] Multiple sets of connecting rods 10 and top blocks 9 are provided. When the operator replaces the sealing ring 6, he can pull the ring plate 14. When the ring plate 14 moves, it can squeeze the limiting block 12. The squeezed limiting block 12 can drive the connecting rods 10 to move, thereby achieving the effect of pressing multiple connecting rods 10 at one time, which improves work efficiency. The bracket 13 is set to provide support for the ring plate 14 and at the same time reduce the possibility of the ring plate 14 separating from the connecting rods 10.

[0025] It should be noted that, in order to improve the smoothness of the movement of the ring plate 14, such as Figure 2 , Figure 4 and Figure 5 As shown, a slide rail 21 is fixedly connected to the side surface of the discharge pipe 2, an mounting plate 19 is fixedly connected to the inner wall of the ring plate 14, a rotating shaft is fixedly connected to the upper part of the mounting plate 19, a roller 20 is rotatably connected to the side surface of the rotating shaft, and the side surface of the roller 20 is in contact with the inner wall of the slide rail 21.

[0026] The rollers 20 and the slide rails 21 provide a guiding effect for the movement of the ring plate 14, reducing the possibility of the ring plate 14 deviating and enabling the ring plate 14 to move along the preset trajectory, thereby improving the stability of the ring plate 14. At the same time, the rollers 20 can effectively improve the smoothness of the movement of the ring plate 14, allowing the staff to easily pull the ring plate 14.

[0027] Furthermore, in order to ensure that the sealing cap 4 can be securely connected to the connecting plate 3, such as... Figure 2 , Figure 4 and Figure 6 As shown, a first connecting block 15 is fixedly connected to the side surface of the connecting plate 3, and a second connecting block 18 is fixedly connected to the side surface of the sealing cover 4. A screw 16 is rotatably connected inside the first connecting block 15, and the screw 16 extends into the interior of the second connecting block 18. A nut 17 is screwed onto the side surface of the screw 16, and one side of the nut 17 is in contact with one side of the second connecting block 18.

[0028] After the sealing cap 4 is fastened onto the connecting plate 3, the screw 16 needs to be rotated so that the screw 16 moves into the interior of the second connecting block 18. Then, the nut 17 is rotated until the nut 17 and the second connecting block 18 are tightly fitted together, thus achieving a firm connection between the sealing cap 4 and the connecting plate 3, which can effectively reduce the possibility of leakage of aluminum silver paste during ball milling.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
