[0018] See also Figure 3-4 Each of the fixing blocks 20 is in the shape of a truncated cone.

[0019] See also Figure 3The inner diameter of the air outlet pipe 23 is smaller than the thickness of the scraper 21; by setting the fixing block 20, the fixing block 20 is truncated into a cone shape, and the second slot hole 26 is gradually blocked to prevent the paste from adhering to the second slot hole 26 when flowing out of the second slot hole 26. At the same time, the second slot hole 26 is cleaned to prevent blockage and improve the modulation efficiency.

[0020] During operation, the electric cylinder 13 is started to pull up the scraper 21; after opening the cover plate 14, the raw material is poured into the feeding port 12, and the raw material cannot pass through the slot 2 26, and can only slide down from the stirring blade 19 along the gap between the stirring blade 19 and the slot 1 22; the motor 15 is started, and the motor 15 drives the rotating shaft 18 to rotate, and then the rotating shaft 18 drives the stirring blade 19 to rotate, and the raw material paste is thrown to the inside of the mixing tank 10 by the stirring blade 19, and as the raw material is gradually poured in, the raw material paste is stirred during the rotation of the stirring blade 19; then the electric cylinder 13 is started, and the output end of the electric cylinder 13 slowly moves During the slow reciprocating motion, the scraper 21 is pressed down, and the raw material paste flows out from the gap between the slot 1 22 and the stirring blade 19, and the raw material is squeezed out from the slot 2 26, so that the raw material on the lower side of the modulation tank 10 overflows from the lower side to the upper side of the scraper 21. As the slot 2 26 moves downward, the fixed block 20 gradually blocks the slot 26. As the stirring blade 19 rotates, the paste on the lower side is completely turned up, increasing the uniformity of the zinc paste mixing; the harmful gas in the modulation process is extracted by the outlet pipe 23, and after being purified by the filter 17, the emission of harmful gas is reduced, and the modulation is continuously performed and completely mixed.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
