Therefore, the pressing plate 804 presses the hot melt adhesive solution downward, and the hot melt adhesive solution without impurities can be squeezed out from the filter screen plate 903, and the impurities are left above the filter screen plate 903. At this time, the pressing plate 804 is rotated and removed, and the servo motor 807 is started to drive its output shaft to drive the I-shaped shaft 812 to rotate inside the rotating hole 811. At the same time, the rotating rod 813 and the rotating blade 814 are driven to rotate.
