The distance between the bottom plate 51 and the second positioning plate 53 is greater than the diameter of the pressing rod 33. The pressing rod 33 is located between the bottom plate 51 and the second positioning plate 53, which facilitates the pressing cylinders 3 on both sides to synchronously drive the two pressing materials to pass between the bottom plate 51 and the second positioning plate 53, thereby ensuring the clamping and positioning of both sides of the material tray 5 and ensuring the positioning accuracy.

[0049] Usage Process
