What is the control of the adhesive amount for Screw breaking valve
1、 The principle of controlling the amount of glue in the Screw breaking valve
The Screw dispensing valve uses a screw as the driver to control the glue to flow out from the screw outlet and complete the dispensing process. There are various ways to control the amount of adhesive, as described below.
2、 Manually adjust the adhesive amount
Manual adjustment is the most primitive control method, which manually rotates the handle to control the rotational speed of the screw, thereby adjusting the flow of glue. This method is simple and easy to understand, but requires experienced technical personnel to operate, which is prone to errors.
3、 Digital control
Digital control can adjust the rotational speed of the screw according to the set parameters to achieve precise control of the adhesive amount. Digital control can improve production efficiency and control real-time flow, making it less prone to errors. However, digital control equipment is expensive and requires professional maintenance.
4、 Weight control
Weight control uses a quality sensor to measure the weight change in the container and calculate the flow rate of glue, thereby controlling the amount of glue. This method is relatively accurate and can easily achieve automated control, but attention should be paid to the accuracy of the sensor and the sensitivity of the weight sensor to prevent errors.
5、 Advantages, disadvantages, and applicable scenarios
Manual adjustment of the adhesive amount is very flexible, suitable for small amounts of dispensing processes with low strength requirements, while digital control and weight control are suitable for large amounts of dispensing processes with high precision requirements. However, digital control and weight control equipment are expensive and require significant investment in costs; The application range of manually adjusting the adhesive amount is narrow and not suitable for mass production.
In summary, there are various ways to control the adhesive amount of Screw breaking valve, and choices can be made according to different requirements and scenarios
