3results about How to "Avoid synchronous rotation" patented technology

The utility model discloses a mixing device for plastic production, which belongs to the technical field of plastic product production and comprises a mixing bin, a motor is fixedly connected to the top of the mixing bin, a driving gear is fixedly connected to an output shaft of the motor, a rotating shaft is fixedly connected to the bottom of the driving gear, and the rotating shaft is fixedly connected to the top of the mixing bin. Long scraping plates are rotationally connected to the two sides of the bottom of the gear ring, a first connecting rod is fixedly connected to the inner end face of one long scraping plate, a first crushing ball is fixedly connected to the front face of the first connecting rod, a second connecting rod is fixedly connected to one side of the rotating shaft, and a second crushing ball is fixedly connected to the front face of the second connecting rod. And by arranging a linkage gear, a first crushing ball and a second push plate, the rotating direction of a gear ring is opposite to that of a driving gear, so that the rotating direction of the first crushing ball is opposite to that of the second crushing ball, large raw materials can be crushed, and the situation that the crushing balls push the large raw materials to synchronously rotate, and consequently crushing is not thorough is prevented.
