[0020] Through the above technical solution, when the device is in use, the piston valve 6 is opened to put the rubber raw material into the mixing barrel 5, and then the piston valve 6 is plugged again, and then the motor 2 is turned on to drive the rotating frame 4 to rotate. In conjunction with the stirring mechanism, the raw materials inside the mixing barrel 5 can be repeatedly stirred during the turning process.
[0021] Specifically, the stirring mechanism includes a rotating shaft 9 rotatably connected to the inner surface of the mixing barrel 5 , and the outer surface of the rotating shaft 9 is rotatably connected to the inner surface of the rotating frame 4 .
[0022] Through the above technical solution, one end of the rotating shaft 9 passes through the rotating frame 4, and the entire rotating shaft 9 passes through the mixing barrel 5 and can rotate.
[0023] Specifically, a stirring frame 10 is provided on the outer surface of the rotating shaft 9 , and a stirring blade 11 is provided on the outer surface of the rotating shaft 9 .
[0024] Through the above technical solution, the stirring blade 11 cooperates with the stirring frame 10 to stir the rubber raw material in different ways.
[0025] Specifically, the linkage mechanism includes a fixed rod 7 fixedly arranged inside the device frame 1 , and a fixed gear 8 is fixedly connected to the outer surface of the fixed rod 7 .
[0026] Through the above technical solution, the fixed gear 8 is always in a fixed state, and the movable gear 13 can perform a circular motion along the outer side of the fixed gear 8.
[0027] Specifically, the inner surface of the rotating frame 4 is rotatably connected with a through shaft 12 , one end of the through shaft 12 is fixedly connected with a moving gear 13 , and the outer surface of the moving gear 13 is meshedly connected with the outer surface of the fixed gear 8 .
[0028] Through the above technical solution, when the movable gear 13 rotates outside the fixed gear 8 , it can rotate by itself under the action of the fixed gear 8 .
[0029] Specifically, a first meshing wheel 14 is disposed at one end of the through shaft 12 away from the movable gear 13 , and a second meshing wheel 15 is disposed at one end of the rotating shaft 9 close to the first meshing wheel 14 .

During this process, the rotating frame 4 will drive the mixing barrel 5 to continuously flip. During the flipping of the rotating frame 4, the moving gear 13 will make a circular motion along the outer side of the fixed gear 8.
