Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, and more specifically, to an explosion-proof liquid filling machine. Background Art

[0002] With the improvement and development of the market economy, the depth and breadth of commodity circulation have been further expanded, and the role and status of the packaging industry in the national economy have become increasingly important. According to the different economic development levels of various countries, the output value of the packaging industry usually accounts for 1.5%-2.2% of the gross national product. The more developed the economy, the greater the proportion of the packaging industry. Filling machines are a type of packaging machinery. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines and granule filling machines; from the perspective of the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] In the prior art, backflow occurs when the bottles are being filled, which results in the inability to install them quantitatively, affects production efficiency, and the filling is not fast enough.

[0004] After searching, a Chinese patent with application number CN201921371134.9 discloses a liquid filling machine, which uses elastic materials to reset. A small amount of liquid cannot flow back through the guide plate, so the liquid flows back into the connecting pipe. The bottom of the V-groove on the liquid outlet pipe is flush with the bottom of the connecting pipe funnel. The liquid flowing back in the connecting pipe flows into the bottle to be filled through the liquid outlet pipe, preventing backflow during the filling process and ensuring quantitative filling.

[0005] When the above-mentioned liquid filling machine is actually used, the bottle is prone to position displacement during the filling process, resulting in the filling head being unable to accurately align with the bottle mouth, thereby affecting the filling accuracy. At the same time, the liquid may splash during filling, causing harmful gases in the liquid to leak out, thereby creating an explosion risk. Utility Model Content
