Problems solved by technology

[0002] An automatic drug dispensing device uses a negative pressure pump to control the suction nozzle to absorb pills. Due to the different sizes and shapes of the pills, two pills may be sucked at a time. The industry usually adjusts the air pressure of the negative pressure pump by changing the current and voltage. However, the negative pressure The pressure pump responds slowly to this adjustment and cannot effectively adjust the air pressure of the negative pressure pump

Abstract

An air pressure adjusting device of an automatic dispensing device comprises a fixed support, a drive unit and an adjusting through-pipe. The air pressure adjusting device also contains an eccentric wheel. The drive unit contains a rotating shaft which is fixed to the eccentric wheel. The fixed support contains a support body and a first interconnecting piece and a second interconnecting piece which extend from the support body. The eccentric wheel is mounted between the first interconnecting piece and the second interconnecting piece. The adjusting through-pipe is arranged on the eccentric wheel and two ends of the adjusting through-pipe are respectively installed on the first interconnecting piece and the second interconnecting piece. The rotating shaft of the drive unit is used for rotating in a first rotation direction to drive the eccentric wheel to rotate so as to make the eccentric wheel squeeze the adjusting through-pipe and rotating in a second rotation direction, which is opposite to the first rotation direction, to drive the eccentric wheel to rotate so as to make the eccentric wheel relax the adjusting through-pipe, thus adjusting air pressure in the adjusting through-pipe.

Description

technical field [0001] The invention relates to an air pressure regulating device, in particular to an air pressure regulating device of an automatic medicine dispensing device. Background technique [0002] An automatic drug dispensing device uses a negative pressure pump to control the suction nozzle to absorb pills. Due to the different sizes and shapes of the pills, two pills may be sucked at a time. The industry usually adjusts the air pressure of the negative pressure pump by changing the current and voltage. However, the negative pressure The pressure pump responds slowly to this adjustment and cannot effectively adjust the air pressure of the negative pressure pump. Contents of the invention [0003] In view of the above, it is necessary to provide a device that can effectively adjust the air pressure. [0004] An air pressure regulating device of an automatic drug dispensing device, comprising a fixed bracket, a driving device and an adjusting through pipe, the a...
