Problems solved by technology
[0004] It takes a certain amount of time to start and stop the motor and to accelerate and decelerate. Therefore, in the control system that realizes the feeding speed and forms a closed loop through speed regulation, it often affects the accuracy of measurement and output; the screw processing and assembly requirements are high; the drive Part of the structure is complex and bulky, and the complex structure also causes problems such as cleaning and disinfection, inconvenience of installation and maintenance, and high failure points

The invention discloses a feeding mechanism of a metering racking machine, which comprises a rotary racking valve; the rotary racking valve comprises a big rotor; a small rotor is arranged in the big rotor; the big rotor and the small rotor are coaxial in center of gyration; the drive shaft of the big rotor is connected with a pneumatic actuator; and the drive shaft of the small rotor is connected with a pneumatic motor. The big rotor and the small rotor are driven by the pneumatic actuator and the pneumatic motor which take compressed air as power to respectively realize rapid and accurate feeding. The feeding mechanism of the metering racking machine has a simple structure, convenience in speed regulation and accuracy in metering.
Description
technical field [0001] The invention relates to a metering and dispensing machine, in particular to a feeding mechanism of the metering and dispensing machine. Background technique [0002] The feeding mechanism is one of the key components of the metering and dispensing machine. The feeding mechanism and its driving mode directly affect the dispensing accuracy, output, cleaning and disinfection and reliability of the metering and dispensing machine. [0003] The metering and dispensing machine in the prior art uses a motor to drive the screw for feeding, which specifically has the following disadvantages: [0004] It takes a certain amount of time to start and stop the motor and to accelerate and decelerate. Therefore, in the control system that realizes the feeding speed and forms a closed loop through speed regulation, it often affects the accuracy of measurement and output; the screw processing and assembly requirements are high; the drive Part of the structure is compl...
