An environment-friendly EPE foamed packaging material preparation device according to claim 3, wherein the feeding frame (101) and the discharging frame (102) have the same structure, the feeding frame (101) or the discharging frame (102) comprises a U-shaped frame (103) fixedly connected to the upper surface of the supporting frame (1), a plurality of rolling columns (104) are rotatably installed at the bottom in the U-shaped frame (103), and U-shaped limiting plates (106) positioned above the rolling columns (104) are detachably connected to two sides in the U-shaped frame (103) through fixing bolts (105).

7. The EPE foam packaging material preparation equipment in environmental protection according to claim 6, wherein the horizontal height of the bottom in the feeding frame (101) is larger than the height of the upper surface of the carrying plate (12), and the horizontal height of the bottom in the discharging frame (102) is smaller than the height of the upper surface of the carrying plate (12) and is arranged obliquely downwards opposite to the carrying plate (12).

8. The preparation method of the environment-friendly EPE foaming packaging material is characterized by comprising the following steps:

conveying the prepared foamed packaging plate to a conveying belt (3);

the plate is conveyed to a plate limiting position opposite to the feeding frame (101) through a limiting baffle (301) on the conveyor belt (3), and then the plate is pushed to enter the range of the bearing plate (12) through the feeding frame (101) through a push rod piece (15);

at the moment, the limiting frame (13) is pushed by the electric push rod (14) to rise to a position capable of wrapping the bearing plate (12) in the upper direction for positioning the plate; after the positioning is finished, the limiting frame (13) can fall back through the electric push rod (14), so that the limiting frame (13) moves to the position below the bearing plate (12);

then the push component (4) can drive the mounting frame (2) and the connecting frame (6) to vertically displace downwards, so that the electric heating strips (9) connected between the electric sliding blocks (8) on the electric heating strips can penetrate through the plate and enter the bearing plate (12) along with the falling of the electric heating strips, and the mounting frame (2) and the connecting frame (6) can also completely displace to the position below the bearing plate (12);

at the moment, the push rod piece (15) pushes and puts the plate again to enter the discharging frame (102), then the push rod piece (15) retracts after the plate falls into other collecting equipment, and the limiting frame (13) also restores to the position above the bearing plate (12); the work is carried out in a reciprocating way.
