[0038] In one embodiment, Figure 1 , Figure 2 and Figure 7As shown, the material preparation bin 200 has an open end with two opposite centering components, the centering components include a fixed side shaft 230, a centering frame 240, a centering roller body 250 and a centering spring 260, the fixed side shaft 230 is fixed on the side wall of the material preparation bin 200 and the middle part of the centering frame 240 is rotatably arranged on the fixed side shaft 230, one end of the centering frame 240 extends to one end side of the material preparation bin 200 and the other end is connected to the side wall of the material preparation bin 200 through the centering spring 260, the centering roller body 250 is arranged on the centering frame 240 and extends to the end of the material preparation bin 200; the two centering roller bodies 250 are arranged on the centering frame 240 and extend to the end of the material preparation bin 200; The centering springs 260 in the components have the same elastic coefficient; in the implementation of the present invention, when the box plate 400 is pushed into the interior of the material preparation bin 200, the box plate 400 is located between the two centering components. Under the elastic force of the centering spring 260, the centering roller body 250 rolls against the side of the box plate 400. Since the elastic coefficients in the two centering components are the same, the two centering roller bodies 250 push the box plate 400 to the middle position of the material preparation bin 200 in a rolling clamping manner, thereby ensuring that the box plate 400 is accurately positioned when it is pushed between the upper pressing component 600 and the lower supporting pressing component 700.
