[0028] Specifically, the starch-rich crop raw materials such as corn and wheat are crushed, screened and pretreated, the pretreated raw materials are fermented to produce lactic acid, the lactic acid is subjected to polymerization reaction to generate PLA, the PLA is melted and extruded into a film or a film blanket, an aluminum layer is plated on the PLA film or film blanket to form an aluminum heat insulation film blanket, and then a PLA type aluminum heat insulation film is made. After the PLA film is produced, it is placed on the conveying device 2 for conveying. The PLA film is conveyed into the aluminum plating device body 1. The aluminum plating device body 1 evaporates aluminum molecules and attaches them to the PLA film to achieve the effect of aluminum plating on the PLA film. Then the PLA film is conveyed into the drying box 3. The drying device body 5 produces drying gas, which is transmitted to the air collecting box 11 through the communication pipe 10. The drying gas is conveyed into the dispersion pipe 12 and dried through the gas outlet head 13. When different widths of PLA films need to be dried, the driving motor 14 is started. The output end of the driving motor 14 drives one of the transmission wheels 16 to rotate. The transmission wheel 16 drives the other transmission wheels 16 to rotate through the transmission belt 17. The two transmission wheels 16 drive the bidirectional screw rod 15 to rotate. The screw teeth on the inside surface of the bidirectional screw rod 15 are symmetrical and opposite. When the bidirectional screw rod 15 rotates, it drives the two sliding blocks 7 to move towards or away from each other. The sliding blocks 7 drive the blocking strips 8 to move in the moving grooves 18. The spacing between the two blocking strips 8 is adjusted to be suitable for the width of the PLA film. The two blocking strips 8 block the moving opening 4, thereby reducing heat loss and reducing the cost of producing the PLA type aluminum heat insulation film.

[0030] Specifically, when the sliding block 7 moves, the moving plate 19 is moved, the space in the drying box 3 is reduced, and the loss generated during drying is further reduced. When the moving plate 19 moves and abuts against one end of the dispersion pipe 12, the moving plate 19 extrudes one end of the dispersion pipe 12, one end of the dispersion pipe 12 is rotationally connected with the air collecting box 11, so that the dispersion pipe 12 is extruded and rotated. At this time, the elastic element 21 is compressed, the elastic element 21 is a spring, and the space in the drying box 3 can be further reduced. The PLA film after being plated with aluminum can be dried. When it is necessary to dry the PLA film after being plated with aluminum again, the driving unit 9 is started again to drive the sliding block 7 to move in the opposite direction. At this time, the tension of the elastic element 21 drives the two dispersion pipes 12 to rotate in the opposite direction. The dispersion pipes 12 return to the starting position, the sealing strip 22 improves the sealing effect of the sealing strip 8 after sealing the moving opening 4, and the guide roller 23 is used for guiding the PLA film during conveying.
