[0041] In a specific embodiment, the top cover of the first material barrel and the top cover of the second material barrel are both provided with a gas outlet hole for connecting to a venting pipeline. Preferably, the gas outlet hole is connected to the venting pipeline through a back pressure valve. Understandably, generally, the inert gas atmosphere is maintained in the material barrel (including the first material barrel and the second material barrel) by introducing inert gas, and many solutions have volatility, therefore, the pressure in the material barrel and the exhaust gas are adjusted in time by arranging the venting pipeline. The first material barrel and the second material barrel are respectively and independently connected to the venting pipeline.

[0047] In the specific embodiment, the second outlet of the three-way valve (including the first and second three-way valves) is connected to the vent pipeline, which can balance the pressure in the first and second material buckets and maintain the stability of the pressure in the first and second material buckets; in the vent pipeline, a check valve and a hand valve are arranged in the pipeline section connected to the second outlet of the three-way valve (including the first and second three-way valves) to facilitate the control of the outflow of gas from the second outlet of the three-way valve (including the first and second three-way valves); the check valve prevents the backflow of gas in the vent pipeline to the three-way valve (including the first and second three-way valves).

[0048] In the specific embodiment, the nitrogen pipeline upstream of the first and second three-way valves is provided with a switch valve and a PCV valve to control the supply of nitrogen.

[0050] Reference Figure 1 The working process of the utility model is as follows: the inert gas pipeline supplies inert gas (regulated by a PCV valve) to stabilize the system pressure, ensuring that the system maintains a stable inert gas atmosphere and pressure during production; during the production process, for example, the first discharge on-off valve and the diaphragm pump are first opened (at this time, the second discharge on-off valve of the second material barrel is in a closed state), the material in the first material barrel is conveyed to the first feeding cavity through the first feeding gun head and then to the reaction equipment; after the material in the first material barrel is used up, the first feeding cavity has no material, and the first low liquid level tuning fork issues an alarm; at this time, the first discharge on-off valve is closed, and the second discharge on-off valve is opened manually or automatically, the material is supplied from the second material barrel, and the first material barrel is added with material for standby use; it should be noted that during the working process, other valves, such as hand valves and on-off valves, can be opened as needed, and details are not described here.
