The solution of stepper motors in the field of precise control of pharmaceutical filling machines
1. Introduction
Pharmaceutical filling machine has an important position in the pharmaceutical industry, and has high requirements for its operation accuracy and speed. The use of stepper motor to automatically control the pharmaceutical filling machine can improve the equipment performance and production efficiency. This article discusses how to realize the automatic control of stepper motors using stepper motors in pharmaceutical filling machines from the perspective of engineering developers.

2. System composition
The automatic control system of pharmaceutical filling machine using stepper motor is mainly composed of the following parts:
(1) Stepper motor and driver;
(2) sensors and actuators;
(3) Host controller (such as single-chip microcomputer or PLC);
(4) Man-machine interface (such as touch screen);
(5) Electrical components and power supply.
3. System design principles
When designing the automatic control system of the stepper motor for the pharmaceutical filling machine, the following principles should be followed:
(1) High integration: close integration of all parts to reduce system volume and reduce costs;
(2) Easy maintenance: the system structure is simple, easy to maintain and troubleshoot;

(3) Reliability: the use of components with high reliability to ensure the long-term stable operation of the system;
(4) Extensibility: It has good scalability, which is convenient for later upgrades and function expansion.
4. System function module
According to the functional requirements of the pharmaceutical filling machine, the automatic control system is divided into the following modules:
(1) Measurement module: use sensors to measure the flow, pressure and other parameters of the filling liquid in real time to provide real-time data for the control system;

There are several methods to control the filling volume of liquid filling machine:
1. Manual adjustment. It needs to be carried out by personnel with operating experience, and the adjustment can only be made to the general capacity, and it also needs to be accurately measured with a measuring cup.
2. Electric or computerized adjustment. The equipment is equipped with a non-digital display capacity panel, only the stainless steel measuring cup is excellent and reasonable, the error is within the specification, and there is no need for measuring cup.
3. Overall adjustment. All filling valves of the liquid filling machine adjust the volume consistently, and are equipped with a capacity display, which is easy to control in operation.

4. Adjust independently. Each filling valve on the equipment needs a single adjustment, the capacity scale is a reference, and the measuring cup calculation measurement adjustment is generally required.
