The working process of the automatic tire scraping device of the embodiment is that the tire to be scraped is horizontally placed on the surface of the belt feeder 11, the tire is moved to the top along with the movement of the belt feeder and slides into the input station frame 12, and the tire is changed from a horizontal state to a vertical state. The tire moves from the input station frame 12 into the shaving mechanism, and the two driving rollers 23 rotate in the same direction under the driving of the main motor 231 to drive the tire to rotate at a high speed. The tire tread burr scraping knife component is driven by the tire tread scraper driver to contact the tire tread and separate left and right, and tire burrs are inserted into the cutting edge by means of high-speed rotation of the tire and speed difference between scrapers, so that the tire burrs are separated from the tire body. Meanwhile, the sidewall scraper component is driven by the sidewall scraper driver to contact the sidewall and move from bottom to top along the profile of the sidewall to remove sidewall tire hair. Because the tire moves at a high speed, the tread scraping knife and the sidewall scraping knife move slowly, and when the horizontal movement distance of the scraping knife is less than the contact length of the scraping knife and the tread, the tire rotates at a high speed for more than 1 week, so that the scraping knife can completely contact all areas of the tread and the sidewall of the tire. When the tread scrapes the hair and moves to both sides to the centre promptly, can accomplish the child hair of whole tire tread and clear away, when the tire side scrapes the hair sword and moves to the tire shoulder from the bottom up, can accomplish the child hair of whole tire side wall and clear away. And the tread scraping knife assembly moves to the tire shoulder part, and the tread scraping knife assembly is lifted to return. And moving the tire side burr scraping knife component to the tire shoulder, and finishing removing the tire burrs. And (4) driving the roller to decelerate until the roller stops rotating, starting the tire removing mechanism to work, and conveying the tire to an output station frame to finish a cycle. And restarting the tire hair removal work of the next tire to ensure that the tire hair removal cycle time is completed in a short time. In addition, the fetal hair collecting device is arranged to prevent the fetal hair from splashing, and the absorption pipe of the fetal hair collecting device is a vacuum suction pipe. The scraped lanugo can be sucked into the lanugo collecting box in time, and the lanugo in the collecting box is cleaned regularly.
