[0010] Beneficial effects

[0011] Compared with the prior art, the utility model has at least the following advantages: The hot air flows through the interlayer of the stirring cylinder and the cavity of the convex column and then uniformly heats the side wall and the middle part of the stirring cylinder, and returns to the air inlet pipe through the air outlet pipe and enters the heating cylinder to continue heating, so as to carry out hot air circulation heating on the materials inside the stirring cylinder; The liquefied resin is output by the resin circulation output pipe under the action of the pump body, heated by the heating cylinder and then circulated back into the stirring cylinder again, realizing the circulating heating of the resin flow, and further increasing the uniform heating of the resin during stirring.
