[0025] In this embodiment, when the started electric push rod 42 pushes the vertical plate 43 to drive the plastic packaging bag on the first placement plate 49 to move out, the winding drum 47 can be pulled to rotate through the connecting rope 46 to reel in the other end of the connecting rope 46, thereby pulling the second placement plate 49 and the clamping block 410 at its upper end to slide into the processing warehouse 2, so as to realize automatic unloading and automatic loading at the same time.

[0026] Among them, a number of ventilation holes are opened inside the first placement plate 45 and the second placement plate 49, and the ventilation holes are evenly distributed on the first placement plate 45 and the second placement plate 49. Through the ventilation holes, the plastic packaging bags placed on the first placement plate 45 and the second placement plate 49 can be evenly heated and dried.

[0027] In addition, a connecting groove located on the outside of the support spring 44 is opened on the side of the second placement plate 49 close to the support spring 44, and the number of the first placement plates 45 and the second placement plates 49 are three, and the three first placement plates 45 and the second placement plates 49 are equidistantly distributed on the processing warehouse 2, so that the three first placement plates 45 and the second placement plates 49 can be staggered and equidistantly distributed on the processing warehouse 2 from top to bottom.

[0028] Secondly, there are six support springs 44, which are symmetrically distributed in groups of two on the inner wall of the processing chamber 2, and each group of support springs 44 supports a second placement plate 49. The second placement plate 49 is supported by groups of two support springs 44, so that the second placement plate 49 can slide stably laterally.

[0029] Then, the upper ends of the first placement plate 45 and the second placement plate 49 are fixedly connected with U-shaped blocks, and the clamping block 410 is rotatably connected to the inner side of the U-shaped block through a rotating shaft.
