Production Description:
Hot melt gluing machine temble:
Dispenser thimbles, also commonly known as dispensing valves or thimble dispensing valves, are a key component in a dispensing machine. The following is a detailed analysis of the dispenser thimble:
I. Definition and Function
Dispenser thimble is a firing type glue valve with piston rebound self-protection function, normally in the closed position. Its main function is to control the outflow of glue to achieve accurate dispensing operations. The amount of glue dispensed depends on the length of time the valve is open, the size of the supply pressure, the type of needle and the viscosity of the fluid.
Second, the principle of work
Closed state: in the absence of starting air pressure, the piston and the needle assembly composed of the needle by the spring compression force, downward force, so that the head of the needle and the needle internal plane part of the close contact to prevent the flow of fluid through the needle, so that the glue valve in the closed state.
Open state: when applying a certain valve pressure (usually not less than 0.45MPa), the piston drives the needle upward movement, the needle and the needle separation, the fluid in the supply pressure through the nozzle and the needle outflow, so that the glue valve is in the open state.
Closing process: when a dispensing action is completed, start the air pressure is reduced or closed, the piston under the force of the spring quickly drive the needle downward movement, the air in the valve body is also discharged from the air inlet, to achieve the purpose of a clean and rapid break off the glue.
Application Scenario
Dispenser thimble is widely used in industries that require precise dispensing, such as electronics, semiconductor, LED, automotive, medical and other fields. It is suitable for all kinds of viscosity fluids, including glue, paint, ink and so on.
IV. Features and Advantages
High precision: High-precision dispensing operation can be realized by precisely controlling the valve opening time and supply pressure.
High efficiency: Used with pneumatic dispensing controller, dispensing time can be set and dispensing pressure can be adjusted to realize automatic dispensing process and improve production efficiency.
Stability: With piston rebound self-protection function, it can effectively prevent glue backflow and leakage.
Durability: made of high quality material, it has good wear resistance and corrosion resistance to prolong the service life.
V. Maintenance and care
Regularly check the wear and tear of the and needle, and replace the parts with serious wear and tear in time.
Regularly clean and maintain the thimble of the dispenser to keep its internal cleanliness and lubrication.
Pay attention to check the stability of the air pressure system and the accuracy of the supply pressure to ensure the stability and accuracy of the dispensing operation.
