as shown in fig. 7-10, fig. 12, the driving fluted disc 111 drives the driving gear 1111 to rotate, and drives the first bevel gear 225 to rotate through the clutch wheel 224, the first bevel gear 225 drives the third bevel gear 2274 to rotate through the second bevel gear 226, the third bevel gear 2274 drives the first rotating shaft 2273 to rotate through the first belt 22731, the first rotating shaft 2273 drives the first scraping knife 22721 to scrape the burrs on the upper surface of the concave part in the forming part through the first rotating belt 2272, the first rotating shaft 2273 drives the second rotating shaft 2275 to rotate through the second belt 22732, the second rotating shaft 2275 cleans burrs which are mixed in the first scraping knife 22721 through the second scraping knife 22751, and simultaneously scrapes burrs which are relatively concentrated at the corners of the forming concave part, and the burrs which are cleaned in the second scraping knife 22751 are staggered through the first cleaning plate 22752, and the burrs which are cleaned fall into the first accommodating frame 2276 to be recovered, so that the scraping part can be automatically arranged, and the scraping part cannot be continuously scraped by the scraping part can be prevented from being continuously blocked;
as shown in fig. 9 and 11, when the second rotating shaft 2275 rotates, the second rotating shaft 2275 drives the third rotating shaft 2281 to rotate through the third belt 22753, the third rotating shaft 2281 drives the third hooking blade 2283 to rotate through the second rotating belt 2282 so as to scrape burrs on the outer surface of the formed part, and then the burrs are cleaned at the second cleaning plate 2284 which is staggered with the third hooking blade 2283, and the cleaned burrs fall into the second accommodating frame 2285 and are collected, so that the effect of synchronously scraping the sealing ring formed part in multiple directions by adopting a mode of transversely supplementing the formed part to longitudinally scrape the scraped part is achieved, and the scraping is more sufficient and has no dead angle;
as shown in fig. 10 and 12, according to the present invention, a first accommodating frame 2276 and a second accommodating frame 2285 are respectively disposed below a second rotating shaft 2275 and below a second cleaning plate 2284, and the length of a second hooking knife 22751 is sequentially shortened from two sides of the second rotating shaft 2275 to the middle of the second rotating shaft 2275, so as to, when an actual sealing ring molded part is discharged, more burrs are formed at the outer circular arc of the annular molded part near the inner concave part, and the second hooking knife 22751 formally cleans the burrs near the outer circular arc located at the concave part of the molded part, so that the length of the second hooking knife 22751 is sequentially shortened from two sides of the second rotating shaft 2275 to the middle of the second rotating shaft 2275, so that the second hooking knife 22751 is fully contacted with the outer circular arc, the removed burrs are ensured to be more fully discharged into the first accommodating frame 2276 in a short time, and the more burrs treated by the second hooking knife 22751 are prevented from interfering with the second scraping part 228 to treat the outer circular surface with less burrs;
it should be added that, when the forming part is driven to rotate by the positioning column 113, the burrs at the corners of the concave parts are difficult to fully extend due to the size of the equipment, and can be carried out by the corner cleaning piece 22711, and the burrs at the shorter transition sections of the second rotating shaft 2275 and the third rotating shaft 2281 are scraped off by the transverse scraping plate 22761 and fall into the first accommodating frame 2276.
After the burr is removed, the cylinder in the guide post 313 drives the driving block 316 to separate from the push rod 220 and move upwards through the pressing piece 315, as shown in fig. 7, at this time, the thrust spring 223 pushes the mounting frame 221 to move, so that the mounting frame 221 drives the clutch wheel 224 to separate from the driving fluted disc 111 to return to the initial position.
