[0025] Working principle: When the device is in use, the copolyester hot melt adhesive powder raw material and the mixed material are poured into the device body 1 through the feed port 9, and the exhaust pump 12 is turned on at the same time. When the exhaust pump 12 is turned on, the air inside the device body 1 is discharged through the air pipe 15, so that the inside of the device body 1 is in a negative pressure, and the air at the feed port 9 is sucked into the device body 1, so as to avoid dust when the feed port 9 is added. When the exhaust pump 12 discharges the air inside the device body 1, the air passes through the filter plate 14 on the top of the filter box 13, and the dust in the air can be filtered through the filter plate 14. Driven by the second motor 18, the brush roller 17 can rotate, and the rotating brush roller 17 will brush and clean the filter plate 14 to avoid dust blocking the filter plate 14.

The slot 16 allows the material slot 16 to be disassembled. After mixing, the solenoid valve 5 is opened to allow the material inside the device body 1 to be discharged through the discharge pipe 6. At the same time, the air intake pump 11 will pump air into the device body 1. The material inside the device body 1 can be discharged from the discharge pipe 6 faster under the push of the top air pressure, which is beneficial to improve the discharge efficiency. While discharging the material, the second electric heating coil 19 will heat the discharge pipe 6 to prevent the hot melt adhesive inside from solidifying and causing blockage when it contacts the discharge pipe 6 with a lower temperature. When the stirring frame 4 stirs and mixes the internal materials, the cover plate 8 and the feed port 9 remain sealed. The exhaust pump 12 will extract the air inside the device body 1, so that the inside of the device body 1 is in a vacuum state, and then the bubbles generated during the stirring process of the hot melt adhesive can float upward in a vacuum state, thereby reducing the bubbles inside the hot melt adhesive and achieving a defoaming effect, thereby preventing excessive bubbles inside the hot melt adhesive from affecting use.
