[0031] The lower heat treatment assembly 3 includes a bottom air inlet bin 301 disposed in the middle of the bottom end of the roller conveyor frame body 1 , and the sides around the bottom air inlet bin 301 are connected to a hot air flow conveying pipe 302 .

[0032] The top end of the hot air flow conveying pipe 302 is connected to the top drying chamber 201 , and a bottom connecting plate 303 is provided in the bottom air inlet chamber 301 , and a plurality of hot air flow dispersion holes 304 are opened on the bottom connecting plate 303 .

[0033] The inner wall of the top heating chamber 203 is symmetrically and obliquely provided with two air guide plates, which are located above the heating resistance wire 205 .

[0034] The hot air generated by the fan 204 when it is started can be blown toward the heating resistor wire 205 in a more concentrated manner.

[0035] The middle connecting plate 208 is in a triangular shape with a raised middle portion and curved sides.

[0036] The hot air entering the top of the middle connecting plate 208 can be transported downward through the air flow holes 209 and can also be introduced into the hot air flow conveying pipe 302 connected to the side of the air volume dispersion bin 207.
