Among them, the pressing mechanism 200 is disposed on the top side of the frame 100, and the conveying mechanism 300 is cooperatively disposed at both ends of the pressing mechanism 200. Thus, the conveying mechanism 300 can convey a plurality of stacked EVA sheets to be pressed to the output end of the pressing mechanism 200 and convey the pressed product from the pressing mechanism 200 to an external blanking device. Specifically, the pressing mechanism 200 includes a first pressing component 210, a second pressing component 220 and a limiting component 230. The first pressing component 210 is disposed on the top of the frame 100, the second pressing component 220 is disposed on the bottom of the frame 100, and the limiting component 230 is disposed between the first pressing component 210 and the second pressing component 220; both ends of the limiting component 230 are respectively connected to the conveying mechanism 300, so that a plurality of cooperatively stacked EVA sheets to be pressed can be conveyed to the limiting component 230 for limited conveying. The EVA sheets move and are positioned between the first pressing component 210 and the second pressing component 220 through the limiting component 230. At this time, the first pressing component 210 can cooperate with the second pressing component 220 to perform pressing treatment on a plurality of stacked EVA sheets. Subsequently, the pressed product is output through the conveying mechanism 300 at the other end.

Thus, the first pressing cylinder 212 can drive the pressing block 213 to cooperate with the corresponding material supporting tray 233 to complete the pressing process of the EVA sheet. Specifically, the horizontal moving assembly 211 includes a horizontal driving cylinder 2111 and a horizontal linear guide rail 2112.
