[0027] ​The driving mechanism 8 comprises a feeding port 801 fixedly arranged on the upper surface of the defoaming filling machine 1, a stirring motor 802 fixedly installed at the middle of the upper surface of the defoaming filling machine 1, a transmission shaft 803 fixedly connected to the transmission end of the bottom end of the stirring motor 802 and penetrating through the defoaming filling machine 1, stirring blades 804 fixedly arranged on the outer surface of the transmission shaft 803, a scraper 805 connected to the outer surface of the transmission shaft 803 above the stirring blades 804 and fully matched with the inner wall of the defoaming filling machine 1, and a discharge pipe 806 fixedly arranged at the bottom end of the defoaming filling machine 1. The purifying mechanism 9 comprises a vacuum pump 901 fixedly installed on the upper surface of the defoaming filling machine 1, a gas feeding pipe 902 fixedly connected to the upper surface of the vacuum pump 901, a gas washing liquid tank 903 arranged on one side of the upper surface of the defoaming filling machine 1, and an activated carbon adsorption plate 904 arranged in the interior of the gas washing liquid tank 903 and below the end of the gas feeding pipe 902 away from the vacuum pump 901. An exhaust pipe 905 is fixedly arranged on the upper surface of the gas washing liquid tank 903.

The stirring motor 802 is started, and the transmission end drives the transmission shaft 803 to rotate, and the stirring blades 804 on the transmission shaft 803 rotate, so that the silica gel adhesive in the defoaming filling machine 1 is fully stirred. In the stirring process, the bubbles in the silica gel adhesive are disturbed, and are more easily separated from the silica gel and rise.
