Charging tray of EVA (Ethylene Vinyl Acetate) particle weighing machine

The utility model provides an EVA particle weighing machine tray which comprises a tray body, a material cup is arranged on the surface of the tray body, a notch is formed in the surface of the tray body, a groove is formed in the surface of the notch, a fixing mechanism is arranged between the groove and the material cup, and the tray body comprises a base layer. And the upper surface of the base layer is fixedly connected with an anti-fracture layer. Through the use of the fixing mechanism, when a material cup is placed, the material cup is placed in a groove, meanwhile, fixing blocks on the surfaces of the two sides of the material cup slide into the groove from sliding grooves in the surface of a notch, then the material cup is rotated, sliding blocks on the surfaces of the fixing blocks move into mounting grooves through the top of the groove, and springs are driven to deform; and the sliding block on the surface is conveniently propped through the elastic force of the spring, so that the sliding block p
