[0029] In use, hot melt adhesive can be injected into the inner box 32. The heating module 34 heats the inner box 32 to prevent the hot melt adhesive from cooling and solidifying. Then, the drive motor 232 drives the rotating shaft 233 to rotate. The stirring frame 235 stirs the hot melt adhesive to improve the anti-solidification effect and guide the hot melt adhesive into the bottom tube 231. It is then transported downward through the conveying blades 234 at the outer end of the rotating shaft 233, moved through the transition tube 22 to the conveying main tube 21, and then carried into the dispensing device body 1 by the conveying shaft 212 for normal operation.

[0030] Furthermore, the hot air in the insulation cavity 33 can enter the insulation cavity 236 through the fan at the opening of the insulation cavity 236 to keep the hot melt adhesive in the bottom pipe 231 warm and prevent it from cooling and solidifying during transportation. Similarly, the air inlet pipe 2132 can drive the hot air in the insulation cavity 33 into the insulation cavity 1 213 through the fan in the middle of its interior to keep the hot melt adhesive in the main conveying pipe 21 warm and ensure the smooth transportation of the hot melt adhesive.
