How to control the dispensing amount of the fully automatic glue dispenser

When enterprises purchase fully automatic glue dispensers, they all hope to control the amount of glue produced, which is also a concern for them. If the control is good, it can save materials for the enterprise. For fully automatic glue dispensers, if they want to control the standard amount of glue produced, operating in a formal way can bring some control to the enterprise and also bring higher work efficiency, Below, the editor of Helishi will share various methods for controlling the amount of glue produced:

Firstly, the piston pressure
The present invention adopts a closed annular dispensing machine, relying on matching columns and columns. After determining the amount of glue applied in the column volume, it moves downwards inside the column to push the glue solution, which can obtain a certain amount of glue and shape.

The advantage of this method is that it is faster than the first two methods and can transport high-pressure oil. The outlet flow rate can be adjusted by controlling the air pressure, and the time required for extrusion will not change due to the size of the droplet point, thus maintaining a certain work efficiency. It is easier to achieve fast and accurate dispensing, and can be repeated. It is suitable for dripping liquids with different high-pressure oilsDisadvantages: Automatic glue dispensers require frequent cleaning, the cleaning process is complex, and equipment investment is high; This method is not suitable for use when the glue contains large particles

Secondly, the time pressure method
This is the earliest method applied to T-T, which obtains the predetermined amount of glue and the diameter of the glue point by controlling time and air pressure. Usually, the amount of glue increases with the increase of pressure and time, and the allocated volume of glue droplets is a function of the pressure and time acting on the syringe glue liquid.

You can spray some glue
This is a newly developed dispensing technology. Its basic principle is similar to the inkjet principle of an inkjet printer. By applying sufficient force to the liquid, the material can automatically separate. Under the action of colloid pressure, the colloid fills the gap between the spray needle and the syringe

Firstly, the spray needle moves upwards under the action of air pressure and stays at the highest position for a certain period of time. Under the action of spring force, the spray needle moves downwards, and the end spherical surface collides with the base. The flowing glue is cut off, and the glue is sprayed out at high speed from the nozzle, forming glue droplets. Next, the spray needle stays in the lowest position for a period of time, and then moves upwards to start the next cycle of movement

The batching method of the screw pump
The present invention adopts a rotary pump pressurization technology to drive the coating, which has high repeatability and accuracy and can be used for the adhesive with the worst coating performance.
. The device adopts thrust drive to rotate the screw at a precise distance or angle, and its working mode can produce repeatable adhesive droplets with specific pressure

I hope that through the summary of the above four points by the Helishi editor, we can help enterprises control the dispensing volume of the dispensing machine, bring better work efficiency to enterprises, and effectively support the relevant operational knowledge of fully automatic dispensing machines.
