[0024] First, the operator puts the rubber material 11 between the L-shaped plates 7 on the left and right sides, and then the elastic sheet 8 contacts the rubber material 11 to fix it, and then places an appropriate amount of weight 10 on the fixing plate 9. The guide rod 4 moves downward to drive the horizontal plate 5 to move downward, the first spring 6 stretches, the horizontal plate 5 moves downwards and the L-shaped plate 7 drives the rubber material 11 to move downwards, and the rubber material 11 moves downwards and When the grinding wheel 16 touches, the drive motor 15 can be started. The drive motor 15 rotates to drive the grinding wheel 16 to rotate. The grinding wheel 16 rotates to polish the rubber material 11, and then conduct abrasion resistance test. The rubber slag that appears during grinding is easy to shoot , And then the arc-shaped baffle 13 blocks the projected rubber slag, and prevents the rubber slag projecting from causing injury to surrounding workers. When the rubber material 11 is tested, the guide rod 4 can be pulled up to move, and then the L-shaped plate 7 moves up to drive the rubber material 11 to move up. When the rubber material 11 moves up and does not contact the grinding wheel 16, the pulling guide can be stopped. Rod 4, remove the rubber material 11, and place another rubber material 11 between the left and right L-shaped plates 7 for abrasion resistance test. After the rubber material 11 has all undergone abrasion test, the driving motor 15 can be turned off.
