[0035] The specific usage and function of this embodiment are as follows:

[0036] When in use, the staff first completes the debugging of the equipment, then pulls the closing cover 6 through the handle 63 to separate it from the feed port 5, and then pours the hot melt adhesive raw material into the tank body 2 through the feed port 5. Then, the first motor 31 starts to drive the stirring rod 32 to stir the raw material, and cooperates with the heating coil 9 to heat the raw material to melt it, and the temperature inside the tank body 2 is monitored in real time through the temperature sensor 8;

[0037] Furthermore, after the raw materials are heated, the closing cover 6 is pulled by the handle 63, and then the first magnet 51 and the second magnet 61 generate magnetic coupling, so that the closing cover 6 and the feed port 5 are attracted to each other, and the O-shaped sealing ring 62 is clamped into the sealing groove 52.

Then, the vacuum pump 4 is started to extract the air inside the tank body 2, and the stirring rod 32 is used to stir the raw materials, so that the bubbles generated in the raw materials are extracted more evenly.

[0038] Furthermore, after the vacuuming work is completed, the cylinder push rod 112 is started to push the baffle 114 to slide in the placement groove through the connecting block 113. When the baffle 114 slides to the specified position, the placement groove is sealed by the seal 115 to prevent external air from flowing into the tank body 2 through the vacuum pump 4. Then the second motor 101 is started to drive the screw rod 102 to rotate. Then the processed hot melt adhesive flows from the discharge pipe 7 into the barrel 103, and through the rotation of the screw rod 102, the processed hot melt adhesive is transported, and then extruded and stored through the extrusion head 104. Further, after the extrusion is completed, the staff opens the closing cover 6 through the handle 63, and then processes the subsequent hot melt adhesive raw materials.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
