[0030] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the drawings.

[0031] Please refer toFigures 1-3 As shown in the figure, this embodiment is a pneumatic clutch for a rod mill, including:

[0032] A clutch assembly, which includes a clutch body 11;

[0033] A protection assembly, which includes a fixing ring 21, a telescopic spring 22, a movable plate 23, a baffle 24, a through hole 25, a limiting groove 26, a first filter screen 27, and a fixing block 28;

[0034] The fixing ring 21 is fixedly connected to one side position on the outer surface of the clutch body 11. The telescopic spring 22 is fixedly connected to the peripheral position inside the fixing ring 21. The movable plate 23 is fixedly connected to the outer end position of the telescopic spring 22. The baffle 24 is fixedly connected to the outer end position inside the fixing ring 21. The through hole 25 is opened at the peripheral position of the baffle 24. The limiting groove 26 is opened at the peripheral position inside the baffle 24. The first filter screen 27 is placed on the outer surface position of the clutch body 11. The fixing block 28 is fixedly connected to the peripheral position on the outer side of one end of the first filter screen 27;

[0035] The fixing ring 21 is used to support the telescopic spring 22. The telescopic spring 22 is used to reset the movable plate 23. The movable plate 23 is used to support the fixing block 28. The baffle 24 is used to block the fixing block 28. The through hole 25 is used to penetrate the fixing block 28. The limiting groove 26 is used to place the fixing block 28. The first filter screen 27 is used to block the dust outside the clutch body 11;

[0036] The clutch assembly further includes an air inlet hole 12;

[0037] The air inlet hole 12 is opened at one end position of the clutch body 11;

[0038] The air inlet hole 12 is used to inject compressed gas into the interior of the clutch body 11;

[0039] The through hole 25 and the limiting groove 26 are opened relative to the fixing block 28, and the inner side of one end of the first filter screen 27 is in contact with the outer side of one end of the clutch body 11;

[0040] The fixing block 28 can enter the inner side position of the baffle 24 through the through hole 25 and enter the interior of the limiting groove 26 after rotation;

[0041] The movable plate 23 is located inside the baffle 24, and the movable plate 23 is in contact with the outer side of the first filter screen 27;

[0042] When the outer side of the movable plate 23 and the inner side of the baffle 24 are respectively in contact with both sides of the fixing block 28, the fixing block 28 is fixed between the movable plate 23 and the baffle 24;

[0043] When it is necessary to protect the clutch body 11, the first filter screen 27 is sleeved on the outer surface of the clutch body 11, and the fixing block 28 moves through the through hole 25 towards the inside of the fixing ring 21. The inward movement of the fixing block 28 drives the movable plate 23 to move inward, and the inward movement of the movable plate 23 drives the telescopic spring 22 to be compressed. When the fixing block 28 is located at one end of the baffle 24, the first filter screen 27 is rotated, so that the first filter screen 27 drives the fixing block 28 to rotate to a position corresponding to the limiting groove 26. At this time, under the elastic force of the telescopic spring 22, the movable plate 23 moves outward, and the movable plate 23 drives the fixing block 28 to enter the inside of the limiting groove 26, so that the movable plate 23 and the baffle 24 clamp and fix the fixing block 28, thereby fixing the first filter screen 27 at the outer position of the clutch body 11;

[0044] When it is necessary to remove the first filter screen 27, just operate the above steps in reverse.

[0045] Please refer to Figure 4 As shown in the figure, on the basis of the above embodiment, this embodiment further includes:

[0046] An activity component, which includes a hollow groove 31, a second filter screen 32, a fixing column 33, a scraping plate 34 and a fixing nut 35;

[0047] The hollow groove 31 is opened at the outer end of the first filter screen 27, the second filter screen 32 is sleeved inside the first filter screen 27, the fixing column 33 is fixedly connected to the outer side of the second filter screen 32, the scraping plate 34 is fixedly connected to the outer end of the fixing column 33, and the fixing nut 35 is threadedly connected to the outer surface of the fixing column 33;

[0049] There is a thread structure on the outer surface of the fixing column 33 relative to the scraping plate 34, and the inner side surface of the scraping plate 34 is attached to the outer surface of the first filter screen 27;

[0050] When the fixing column 33 moves inside the hollow groove 31, the fixing column 33 drives the second filter screen 32 to rotate inside the first filter screen 27, and the scraping plate 34 scrapes on the outer surface of the first filter screen 27;

[0051] Working principle: By turning the fixing nut 35 outwards, the fixing nut 35 no longer fixes the fixing column 33. Then, apply a rotational force to the fixing column 33 to make the fixing column 33 rotate along the hollow groove 31. While the fixing column 33 rotates, it drives the second filter screen 32 and the scraper 34 to rotate. The overlapping area between the rotation of the second filter screen 32 and the filter holes of the first filter screen 27 is changed, so that dust of different sizes can be blocked. The scraper 34 scrapes on the outer surface of the first filter screen 27, so that the dust attached to the outer surface of the first filter screen 27 is scraped off, thereby realizing the cleaning of the first filter screen 27.
