Rotary clamping mechanism

The utility model discloses a rotary material clamping mechanism which comprises a support, a lifting air cylinder, a first base plate, a rotary air cylinder, a second base plate and four material clamping air cylinders. The first base plate is mounted at the shaft end of the lifting cylinder and is positioned below the bracket; the rotating cylinder is mounted on the first base plate, and the second base plate is mounted at the shaft end of the rotating cylinder; and the four material clamping cylinders are divided into two rows and are distributed on the second base plate front and back. Therefore, the lifting air cylinder, the first base plate, the rotating air cylinder, the second base plate and the four material clamping air cylinders are combined to form the rotating material clamping mechanism, and the mechanism can achieve rotating feeding of the two material clamping air cylinders and rotating discharging of the other two material clamping air cylinders. Therefore, feeding and discharging are carried
