What are the types of dispensers for fluid control equipment?
|
|
The fluid control equipment is divided into:
1, Single liquid dispensing machine
2, Two liquid dispensing machine and single liquid dispensing machine principle:
Put the glue into the barrel, continuously input into the barrel through the air pressure, and cut off the valve to release the glue. When the valve is closed, the glue will flow out. The longer the opening time of the shut-off valve, the larger the amount of glue, and vice versa.
The control mainly controls the opening time and the closing time of the valve body.
The principle of two-liquid dispenser as following:
The AB glue (two-component glue) is separately loaded into the two barrels of AB, and the amount of the glue is controlled by the pump body under the barrel to achieve a certain ratio. The pump body can be selected according to user requirements: gear pump, screw pump, plunger pump and so on. Because the glue properties of different industries are different (there are different viscosities, glue packing, glue ratio, etc.), according to glue, It would be more appropriate to decide which metering pump to use.
The metering pump simultaneously delivers the two-component glue to the mixing head for mixing. The mixing head adopts a dynamic stirring motor to drive the mixing tube inside the mixing tube to rotate at a high speed to automatically mix the glue evenly (the stirring motor can reach 3000 rpm).
After the operation is completed, the mixing part needs to be cleaned immediately. The machine adopts the automatic cleaning function to automatically clean. The cleaning principle is input into the cleaning barrel by pneumatic method to clean the hydraulic pressure to the mixing tube. The high-speed rotation of the dynamic stirring device is used to discharge and rinse the residual glue. clean.
4. In order to be able to use in different environments, the anti-interference factor to the outside is added to the function of the two-liquid glue filling machine. There are mainly heating, stirring, anti-precipitation, vacuum defoaming treatment, etc., which are easier to use and more intelligent. In addition, the equipment increases the automatic pumping function in the loading, and uses the vacuuming function of the storage cylinder to reach the negative pressure in the storage tank, and puts the suction tube into the rubber bucket to realize automatic pumping. The function reduces the manpower link and correspondingly reduces the possibility of dust entering the glue.
