Semi-automatic dispensing machine is a relatively simple dispensing machine equipment, which consists of pedal switch and dispensing machine controller with simple structure. Semi-automatic dispensing machine, also known as dispensing machine, manual dispensing machine, quantitative dispensing machine, 982 dispensing machine, etc. It is a cheap, convenient and practical dispensing machine. 

Semi-automatic dispensing machine is a kind of packaging equipment named according to the degree of automation. Its main characteristics are flexible packaging, low distribution cost and slightly poor packaging accuracy. Its main components include power switch, air pressure regulator, barometer, mode switch, timing control, vacuum control, breathing hole, pedal switch socket, intake pipe and step-by-step drip volume. Now I'll explain the operation guide of semi-automatic dispensing machine for you.

In the operation guide of semi-automatic dispensing machine, its power switch is a well-known component used to control the opening and closing of power supply. When the semi-automatic dispensing machine is working, the power is turned on, the indicator light is on and the position of "on" is displayed. Pneumatic regulators and barometers are used to control and indicate the air pressure added to the machine (the regulator handle should be adjusted after pulling out). When the semi-automatic dispensing machine places the control circuit in automatic or manual dropping mode, the mode switch is used more frequently.

According to the operation guideline of semi-automatic dispensing machine, the vacuum control part used to adjust the dropping time of semi-automatic dispensing machine is mainly used to adjust the vacuum withdrawal strength applied to the air circuit. The breathing hole of the semi-automatic dispensing machine is a fast connected breathing jack. The pedal switch socket is used to turn on the pedal switch. The high-pressure air enters the droplet injection quantity classification through the intake pipe. It is a component used to control the injection time. It is usually divided into four grades.
