Vacuum alarm device of capsule filling machine

The utility model relates to a vacuum alarm device of a capsule filling machine, the vacuum alarm device of the capsule filling machine comprises a vacuum device, an alarm device and a metering and filling device of the capsule filling machine, and the vacuum device, the alarm device and the metering and filling device of the capsule filling machine are sequentially connected through a vacuum pipeline. A pneumatic pressure switch is installed on a vacuum pipeline, when the vacuum degree of a vacuum pump cannot reach a set value of the pneumatic pressure switch, a signal is output to an intermediate relay, after the intermediate relay is powered on, a normally-open contact is closed, a buzzer sounds, a worker adjusts the vacuum degree after hearing an alarm sound of the buzzer, and then the vacuum pump is started to work. And the problem that the capsule filling quantity difference is too large is solved. 本发明涉及一种胶囊填充机真空报警装置，所述胶囊填充机真空报警装置包括真空装置、报警装置以及胶囊填充机计量填充装置，所述真空装置、报警装置以及胶囊填充机计量填充装置通过真空管道依次连接，本实用新型结构简单，通过在真
