Analysis of the Application of Pneumatic Dispensing Controllers

1. Introduction

The pneumatic dispensing controller, as an important component of the dispensing system, achieves the quantitative and precise coating of glue by accurately controlling air pressure, which is significant for improving product quality, production efficiency, and reducing costs. This article will delve into the principles, characteristics, and application analysis of pneumatic dispensing controllers in various fields.

2. Basic Principles of Pneumatic Dispensing Controllers

The pneumatic dispensing controller mainly uses compressed air as the power source, controlling the flow and pressure of gas through precision pressure regulating valves and solenoid valves, thereby driving the dispensing valve to achieve quantitative extrusion of glue. The core lies in the pressure control system, which can quickly adjust the air pressure according to preset programs or external signals, achieving precise control over dispensing volume, speed, and path. In addition, some high-end pneumatic dispensing controllers are equipped with closed-loop feedback systems that monitor the dispensing status in real-time through sensors, further improving the precision and stability of dispensing.
