Further, the described pin device that seesaws of scraping also comprises and scrapes the pin front-rear linkage, an end connect scrapes before and after the pin in the middle of swing arm, the other end connects scrapes swing arm before and after the pin; Describedly scrape that swing arm has an obtuse angle polyline shaped body before and after the pin; Described have the tractive spring in the swing arm in the middle of scraping before and after the pin, makes not break away from during swing arm campaign in the middle of scraping before and after the pin to scrape pin front and back cam.
Further, the described pin device that moves up and down of scraping also comprises and scrapes the pin upper and lower strut, an end connect scrapes pin up and down in the middle of swing arm, the other end connects scrapes the pin pumping arm action; Described scrape the pin pumping arm action have be " U " font body, " U " word two ends connect respectively scrape pin up and down in the middle of swing arm and scrape the pin connecting rod; The described pin of scraping has the tractive spring in the swing arm in the middle of up and down, makes to scrape pin and do not break away from during swing arm campaign in the middle of up and down and scrape cam about the pin.
Further, the described pin front and back cam of scraping has a sectional wheel profile; Described scrape pin up and down cam have a circular wheel profile.
The utility model when work, the driven by motor camshaft, thereby make be fixed on the camshaft scrape before and after the pin cam and scrape pin up and down cam rotate thereupon.At first, because scraping the profile radius of pin front and back cam changes at first, so scraping the pin device that seesaws starts working earlier, middle swing arm is because the tractive of spring before and after scraping pin this moment, passive around scraping the cam outline motion of pin front and back, middle swing arm is scraped pin front and back swing arm by scraping the drive of pin front-rear linkage before and after scraping pin, makes it to move around arm shaft; Scrape that the pin holder of scraping in the swing arm seesaws before and after the pin thereby make to be installed in, make and scrape scraping needle plate and can arrive below the knitting needle pin of needle-bar is called in person on the pin holder;
When then, scraping pin up and down cam forward the profile radius to and changes; Scrape the middle up and down swing arm of pin because the tractive of spring, passive around scraping pin cam outline motion up and down, scrape the middle up and down swing arm of pin and scrape the pin pumping arm action by scraping the drive of pin upper and lower strut, make it to move around arm shaft, drive simultaneously to be fixed on to scrape and scrape the pin link motion in the pin pumping arm action, terminally rotate around bearing pin with scraping the pin holder of scraping that the pin connecting rod links to each other thereby allow, make and below the knitting needle pin is called in person, scrape the needle plate heel of upwards pushing pin, make the needle latch on the knitting needle open, the coil knocking over.
