[0032] Please refer to Figure 2 and Figure 3 , a fixed plate 4 is fixedly connected to the outer surface of the sieve 3. A sealing piece 5 is fixedly connected to the back surface of the fixed plate 4. The back surface of the sealing piece 5 contacts the inside of the feeding cylinder 2 to seal the gap between the feeding cylinder 2 and the sieve 3, preventing the tin melt from flowing out through the gap.

[0033] Please refer to Figure 3 , a limiting ring 9 is fixedly sleeved on the outer circumferential surface of each control rod 6. The outer circumferential surface of the limiting ring 9 is rotatably connected to the inside of the feeding cylinder 2 to limit the control rod 6 and prevent the control rod 6 from sliding and shifting, increasing the stability of the movement of the control rod 6.

[0034] Please refer to Figure 3, two limiting plates 10 are fixedly connected to the outer circumferential surface of the threaded tube 7. The outer surface of each limiting plate 10 is slidably connected to the blanking tube 2 through an empty groove formed inside the blanking tube 2, restricting the threaded tube 7 to prevent it from rotating with the control rod 6, and prompting the threaded tube 7 to always move horizontally.

[0035] Please refer to Figure 1 and Figure 4 , two fixed seats 11 are fixedly connected to the upper surface of the blanking tube 2. A positioning rod 12 is slidably inserted into each fixed seat 11. Two positioning pieces 13 are fixedly connected to the upper surface of the atomizing tube 1. The outer circumferential surface of the positioning rod 12 is slidably inserted into the inside of the positioning piece 13 respectively. The blanking tube 2 is positioned and restricted by the positioning rod 12 and the positioning piece 13, which is convenient for disassembling and maintaining the blanking tube 2.

[0036] Please refer to Figure 4 , a spring 14 is fixedly connected to the side of the positioning rod 12 away from the positioning piece 13. The other end of the spring 14 is fixedly connected to the inside of the fixed seat 11. Relying on the elastic force of the spring 14, the positioning rod 12 can automatically move back and insert into the positioning piece 13, thereby completing the positioning operation of the blanking tube 2.

[0037] Please refer to Figure 4 , a dial 15 is fixedly connected to the outer circumferential surface of the positioning rod 12. The outer surface of the dial 15 is slidably connected to the fixed seat 11 through an empty groove formed inside the fixed seat 11. A plug rod 16 is slidably inserted into the dial 15. An insertion hole 17 is formed inside the fixed seat 11. The positioning rod 12 can be moved through the dial 15, and the plug rod 16 can be inserted into the insertion hole 17 to restrict the positioning rod 12 to prevent it from moving back under the action of the spring 14, thereby facilitating the removal of the positioning restriction on the blanking tube 2 and facilitating the disassembly of the blanking tube 2.

[0038] Please refer to Figure 1 and Figure 2 , equally spaced auxiliary rods 23 are fixedly connected to the upper surface of the atomizing tube 1. The outer circumferential surface of each auxiliary rod 23 is slidably connected to the inside of the blanking tube 2. The auxiliary rods 23 can assist in the installation of the blanking tube 2, facilitate the docking of the positioning rod 12 and the positioning piece 13, and increase the stability of the blanking tube 2.

[0039] In a tin powder atomizing device in this embodiment, by rotating the control rod 6 to drive the threaded tube 7 to move, the threaded tube 7 drives the positioning plate 8 to move, thereby completing or releasing the positioning operation of the sieve 3, achieving the effect of facilitating the disassembly and replacement of the sieve 3 and reducing the labor intensity of workers, and solving the problem that when replacing the sieve 3 in the existing tin powder atomizing device, the blanking tube 2 needs to be removed first, which is rather troublesome and increases the labor intensity of workers.

[0040] It should be noted that the sealing sheet 5 is made of high-temperature resistant material to avoid being easily damaged by high temperature during the operation.

[0041] The working principle of the above embodiment is as follows:

[0042] When it is necessary to replace the sieve 3 with different sizes of blanking holes, rotate the control rod 6 to drive the threaded tube 7 to move forward, the threaded tube 7 drives the positioning plate 8 to move forward, and then the positioning restriction of the sieve 3 is cancelled. After that, rotate the positioning plate 8 to one side, and the sieve 3 can be removed. After replacing the new sieve 3, rotate the positioning plate 8 back, and then rotate the control rod 6 in the reverse direction to drive the positioning plate 8 to move back through the threaded tube 7, so that the positioning plate 8 presses both sides of the new sieve 3. When it is necessary to disassemble and maintain the blanking cylinder 2, the dial 15 can be toggled to drive the positioning rod 12 to move out of the positioning piece 13, and the insertion rod 16 is inserted into the insertion hole 17 to prevent the spring 14 from pushing the positioning rod 12 to move back automatically. Then the positioning restriction of the blanking cylinder 2 is cancelled, and the blanking cylinder 2 can be directly removed. When installing the blanking cylinder 2, only need to pull up the insertion rod 16, and the positioning rod 12 will move back into the positioning piece 13 under the action of the spring 14 to position the blanking cylinder 2.
