This invention relates to the field of scraper cleaning technology, specifically to a scraper cleaning device and a processing equipment for electrode welding grooves. It includes a liquid inlet assembly, a negative pressure assembly, and a drive unit. The liquid inlet assembly includes a liquid inlet body with a liquid inlet channel. The negative pressure assembly includes a negative pressure body and a scraper. The negative pressure body is movably connected to the liquid inlet body, and a negative pressure chamber is formed within the negative pressure body. The scraper is embedded in the negative pressure body and communicates with the negative pressure chamber, with a portion of the scraper extending out from the negative pressure body. The drive unit is connected to the negative pressure body and drives the negative pressure body to reciprocate on the liquid inlet body, thereby switching the scraper between a working position and a cleaning position. When the scraper is in the cleaning position, the cleaning fluid in the liquid inlet channel flows along the working surface of the scraper to the negative pressure chamber to clean the accumulated material inside the scraper. This significantly improves production continuity, accurately flushes the accumulated material inside the scraper, ensures the cleanliness and geometric consistency of the electrode welding groove, and improves the welding quality and electrical performance of lithium batteries.

It includes: a machine body, with a discharge port fixedly installed on one side of the machine body, and an air-cooling device body fixedly installed on one side of the discharge port. An installation mechanism is provided on one side of the air-cooling device body. In this utility model, by setting up the installation mechanism, the air-cooling device body is fitted onto the outer surface of an installation rod using a fixing ring. A fixing sleeve is fitted onto the outer surface of the installation rod and fixed with a retaining ring. Pushing and rotating a side block threads the threaded sleeve onto the outer surface of the threaded block until the fixing sleeve is fixed on the installation rod, thus completing the installation and fixing of the air-cooling device body. By adding the air-cooling device body to the discharge port of the machine body, the air-cooling device body cools the pellets discharged from the discharge port, preventing the pellets from being discharged at high temperatures and affecting their quality. This provides good cooling and heat dissipation measures when the pellets are discharged, improving the quality of pellet processing by the machine body.
