Moreover, the glue has been heated before entering the dispensing tube, and the excess heat of the heated glue is not well recycled. The heat generated by the heated glue will diffuse into the air, increasing production costs. Utility Model Content

[0030] Working principle: When in use, the glue heater 6 and the dispensing tube 13 are both structures on the dispensing machine. The reason why the glue heater 6 and the dispensing tube 13 are marked on this device is to clarify the installation position of the first fixed shell 2 and the second fixed shell 9. The radiator 7 is installed inside the first fixed shell 2, and the first fixed shell 2 is installed inside the first insulation cover 1. The two sets of first insulation covers 1 are put on the glue heater 6. The first fixing ears 3 are fixed together by bolts, and then the four sets of air intake covers 5 are installed on the first fixed shell 2 to complete the fixation of the first insulation cover 1. The second fixed shell 9 is installed inside the second insulation cover 8, and the two sets of second insulation covers 8 are put on the dispensing machine. Tube 13, fix the second fixing ear 10 together with a bolt, thereby fixing the second insulation cover 8 to the dispensing tube 13, and installing the four sets of air outlet covers 12 on the second insulation cover 8, thereby completing the installation of the second insulation cover 8, inserting the first air pipe 14 into the first fixed pipe 4, inserting the second air pipe 15 into the second fixed pipe 11, connecting the first air pipe 14 and the second air pipe 15 through the connecting pipe 16, the length of the connecting pipe 16 is determined according to the distance between the first air pipe 14 and the second air pipe 15, and then putting the insulation cover 17 on the outer surface of the first air pipe 14, the second air pipe 15 and the connecting pipe 16, and connecting the insulation cover 17 and the first air pipe 1 4 is fixed to the middle of the first fixed tube 4, and the second air pipe 15 and the insulation cover 17 are fixed to the middle of the second fixed tube 11.

The air is heated in the heat release space, and the servo motor 19 drives the fan blade 20 to rotate, so that the heated air inside the first fixed shell 2 enters the first air pipe 14. After the airflow inside the first fixed shell 2 flows into the first air pipe 14, the outside air enters the heat release space inside the first fixed shell 2 from the air intake cover 5, continues to be heated, and enters the air inside the first air pipe 14. The gas enters the second air pipe 15 along the connecting pipe 16, and the gas entering the second air pipe 15 is heated again by the heating pipe 21, so that the hot air enters the second fixed shell 9, heats the glue dispensing tube 13, and thus heats the glue inside the glue dispensing tube 13. By recovering the waste heat, the energy required for reheating the glue is reduced, saving costs. The gas that then enters the second fixed shell 9 flows from the air outlet hood 12 to the outside, forming an air circulation.
