[0042] The feeding driving rod of the embodiment can realize feeding of the liquid silicone when moving upwards and downwards, and the feeding efficiency is greatly improved.

[0046] The second pressing plate 420 can be suitable for a material barrel with a larger internal diameter, when the internal diameter of the material barrel changes and the first pressing plate 49 cannot be tightly matched with the inner wall of the material barrel, the second pressing plate 420 which is matched with the internal diameter of the material barrel can be additionally arranged, and flexibility is improved.

[0047] In summary, the structure of the utility model is reasonable in design, small in size and capable of saving land occupation, the feeding can be realized in 1:1 ratio, the ratio error is small, the operation is stable and reliable, and the operation is convenient.

[0048] The above embodiment is a preferred embodiment of the utility model, but the embodiment of the utility model is not limited by the above embodiment, and any change, modification, replacement, combination and simplification which does not deviate from the spirit and principle of the utility model should be equivalent replacement, and all are included in the protection scope of the utility model.
