Background technology
Field of industrial production can use various glue to cohere parts, sealing etc..Dispensing operation traditionally passes through gas
Dynamic adhesive dispensing device manually completes, and operation principle is that the thrust for pushing push rod to generate moment using air pressure squeezes sebific duct, completes to squeeze
Glue, then point arrive specified position, this kind of operation process efficiency is slow, and non-constant due to air pressure, dispensing amount is uneven, it is difficult to ensure
The stabilization of product quality manually can not then accomplish if necessary at least two glue mixing dispensings.With automatization level into
Step, some enterprises can complete dispensing operation using automatic dropping glue equipment, but due to being difficult to constant air pressure, dispensing amount is not
Uniform problem still has.It is unstable due to dispensing amount for mixing dispensing in the glue short time, it is basic it cannot be guaranteed that mixed
Composition and division in a proportion example can not still accomplish.In actual production, in order to reduce the time for frequently replacing sebific duct, frequently with large capacity sebific duct
