[0003] After searching, for example, the utility model patent with Chinese patent number CN217263032U discloses a feeding device for adhesive products. Through the driving mechanism, the motor is started, and the motor controls the first screw to rotate. The rotation of the first screw drives the first pulley, the belt, the second pulley and the second screw to rotate synchronously, so that the threaded sleeve moves back and forth relative to the first screw and the second screw, driving the connecting rod and the scraper block to move back and forth on the feeding channel, so that the residual rubber can be cleaned and recycled, and the influence of the residual rubber on subsequent production is eliminated, so as to ensure the quality of subsequent products. However, when the device is in use, although the rubber is scraped off from the feeding channel, a part of the rubber will still adhere to the scraper and cannot be removed, and cannot be completely cleaned. Therefore, a butyl rubber feeding device is proposed to solve the above problem. Utility Model Content
