[0026] When the screening device for powder food production is used, Figure 1 , Figure 2 and Figure 3 As shown, when the powdered food needs to be screened, the first motor 2 fixedly connected to the upper end of the base 1 is started to drive the main gear 3 fixedly connected to the front end of the first motor 2 to rotate, and drive the interlocking gear 4 meshingly connected to the right end of the main gear 3 to rotate. When the interlocking gear 4 rotates, the first pulley 5 fixedly connected to the outer side of the interlocking gear 4 rotates at the same time. When the first pulley 5 rotates, it drives the belt body 6 tightly fitted on the outer side of the first pulley 5 to rotate, and the second pulley 7 tightly fitted on the inner side of the right end of the belt body 6 rotates at the same time. The eccentric wheel 8 fixedly connected to the outer sides of the front and rear ends of the pulley 5 rotates, and the eccentric wheels 8 fixedly connected to the outer sides of the front and rear ends of the second pulley 7 rotate simultaneously, so that the screening box 9 tightly fitted to the outer side of the upper end of the eccentric wheel 8 vibrates up and down, and at the same time, the spring 10 fixedly connected to the lower end of the screening box 9 is subjected to pressure and deformed, so that the screening box 9 fixedly connected to the upper end of the spring 10 is constantly shaken, and the powder food dropped from the inside of the screening box 9 is screened, which can make the powder food screened more evenly, avoid dead corners that cannot be screened, and the powder is stuck in the corner;
[0027] like Figure 2 and Figure 4 As shown, when the powder needs to be screened in multiple layers, the screen 11 is fixedly connected inside the screening box 9, and a discharge port 12 is set at the outlet of each layer of the screen 11, and a bag for receiving materials is installed inside the discharge port 12 to avoid dust and air pollution when the powder falls. After being screened by the screen 11, it finally falls into the storage box 14 connected to the internal slot at the lower end of the screening box 9. When the screened powder in the storage box 14 needs to be taken out, the storage box 14 is pulled to the right, so that the outer sides of the front and rear ends of the storage box 14 slide to the right on the inner side of the slot frame 13 until the storage box 14 is separated from the slot connection between the screening box 9, so that the powder food can be screened in multiple layers, and the powders of different specifications can be classified and stored, which is more practical.
[0028] like Figure 2 As shown, when it is necessary to avoid powder agglomeration, the second motor 15 fixedly connected to the right end of the screening box 9 is started, driving the fixed frame 16 fixedly connected to the left end of the second motor 15 to rotate, so that the electric telescopic rod 18 threadedly connected to the outer side of the fixed frame 16 moves to the left or right on the inner side of the threaded rod 17, and the electric telescopic rod 18 is limited, driving the slide plate 19 fixedly connected to the lower end of the electric telescopic rod 18 to scrape above the first layer of screen 11, which can prevent the fallen powder from agglomerating too large and unable to pass through the mesh of the screening net, and can break up the powder and speed up the falling speed of the powder.
