Working principle of screw valve dispensing machine
1、 Overview of screw valves for dispensing machines
The screw valve of the dispensing machine is a commonly used dispensing equipment, widely used in fields such as electronics, automobiles, medical devices, etc. It achieves precise dispensing operation by rotating and pushing the screw to press the glue out of the glue storage tank.
2、 Components of screw valves
The screw valve mainly consists of a screw, a valve body, and a driving device. A screw is a helical pushing device, the valve body is a channel for the flow of glue, and the driving device drives the rotation of the screw through an electric motor or pneumatic device.
3、 Working principle of screw valve
1. Glue supply: Firstly, the glue is stored in the glue storage tank and the supply pressure is controlled by a pressure stabilizer. When the dispensing machine starts working, the glue is pushed from the glue storage tank to the screw valve.
2. Screw rotation: After the driving device is started, the screw begins to rotate. The threads on the screw push the glue from the feeding end of the valve body to the dispensing end
3. Glue flow: As the screw rotates, the glue enters the valve body and flows along the channel until it reaches the dispensing end.
4. Glue accuracy control: By adjusting the rotation speed and feed rate of the screw, the flow rate of glue and the accuracy of glue dispensing can be controlled. Different dispensing requirements can be met by adjusting parameters.
4、 Characteristics of screw valves
1. High precision: The screw valve uses a screw to push the glue, which can accurately control the flow rate and dispensing position of the glue, ensuring the accuracy and stability of dispensing
2. Strong adjustability: By adjusting the rotation speed and feed rate of the screw, different dispensing requirements can be achieved, suitable for various dispensing processes of adhesives
3. Wide application range: Screw valves are suitable for various viscosities of adhesives and can be applied in various fields such as electronic packaging, component fixation, and circuit protection
4. Easy to operate: The screw valve is driven by a motor or pneumatic device, which is easy to operate and does not require complex debugging and installation.
5、 Application field of screw valves Screw valves
Widely used in the electronics industry, such as dispensing for electronic products such as mobile phones and tablets; Automotive industry, such as car lights, instrument panels, and other components dispensing: Sealing dispensing for medical device industry, such as syringes, drug packaging, etc
6、 Summary
Screw valve is a commonly used dispensing equipment that achieves precise dispensing operations through the rotation and pushing of the screw. Its working principle is simple and clear, with a wide range of applications, which can meet the dispensing needs of different fields. In the constantly developing field of adhesive applications, screw valves will continue to play an important role.
