The end of the arm 32 away from the material clamp 31 is provided with a second rotating motor 321, and the second rotating motor 321 is fixedly connected to the rotating chassis 33. The material clamping cylinder 311 drives the material clamp 31 to clamp or release, and the first rotating motor 312 is used to change the clamping angle of the material clamp 31, so as to facilitate the clamping of the rubber sleeve. The second rotating motor 321 adjusts the up and down rotation angle of the arm 32, and the rotating chassis 33 is used to adjust the horizontal angle of the arm 32. The arm 32 and the rotating chassis 33 cooperate to adjust the position of the material clamp 31, so as to facilitate the transfer of the material clamp 31 from the vibration plate 2 to the material pusher 4.
