When in use, the feed frame is first installed into the interior of the mixing cylinder, and then the material for producing pinacolone is delivered into the delivery slot. Then, the material will fall onto the surface of the weighing platform body through the delivery slot, and the weight of the material can be weighed by the weighing platform body. Then, the weighed data will be displayed on the surface of the display screen body, so that the weight of the material can be accurately known, and the overall accuracy effect is good. When the weighing is completed and the feeding starts, the electric push rod is started, and the moving plate can be driven to move by the electric push rod. Thereby, the moving plate will drive the scraper to scrape the material on the surface of the weighing platform body, and then when the moving plate continues to move, the moving plate will drive the material to contact the front surface of the movable plate, so that the movable plate will move backward, and then the movable plate will contract through the spring body when moving, and then it will be limited by the telescopic cylinder, so that the moving plate and the scraper will push the material as a whole. At this time, the movable plate is squeezed, and the feed chute opens, so that the material will fall into the inside of the feed chute as a whole, and then the material will fall into the inside of the mixing barrel through the feed frame, so that the overall pushing effect of the material after weighing is relatively complete, and the material can be transported as a whole to avoid the material remaining on the surface of the weighing platform body. This design can quantitatively control the delivery of the material that needs to be delivered, which reflects the functionality of the design.

[0019] 2. The quantitative control device for the production of pinacolone, through the set moving block, moving plate, connecting block, connecting rack, gear body, rotating shaft, first bevel gear, second bevel gear, rotating cylinder, arc groove, convex column and telescopic column, when in use, when the electric push rod drives the moving plate to move, the moving plate will also drive the moving block to slide inside the slide groove, so that the moving block will drive the moving plate to move, and the moving plate will drive the connecting block and the connecting rack to move, when the connecting rack moves, the connecting rack will mesh with the gear body, so that the gear body will rotate, when the gear body rotates, the gear body will drive the rotating shaft to rotate, at this time the rotating shaft will drive the first bevel gear to rotate, then the first bevel gear and the second bevel gear will mesh, so that the first bevel gear will drive the second bevel gear to rotate, and then the second bevel gear will drive the rotating cylinder to rotate, and then when the rotating cylinder rotates, the convex column moves inside the arc groove, so that the telescopic column can be driven to rotate in the rotating cylinder. The internal telescopic movement causes the telescopic column to move forward, and the movable plate will move backward. At this time, the telescopic column will hit the back of the movable plate, thereby beating the impurities remaining on the surface of the movable plate. Therefore, the front surface of the movable plate will not accumulate material, and the overall quantitative effect is better. This design can avoid excessive material accumulation on the front surface of the movable plate. The rotating cylinder can be supported by the support ring, and the overall support effect is better. Then the position of the support ring can be fixed by the connecting rod. At the same time, the interior of the second quantitative delivery rack can also complete the above operation. Through the design of the first quantitative delivery rack and the second quantitative delivery rack, different materials can be quantitatively delivered at the same time, and then fall into the interior of the mixing barrel, and then fall into the interior of the guide groove again, and then continue to fall into the interior of the processing barrel through the feeding pipe for processing and production. By being able to mix two or more materials in advance in the mixing barrel and the guide groove, subsequent operations are more efficient, which reflects the ingenuity of the design.
