Description

Active liquid agitator

This model relates to a liquid stirrer. Especially with regard to an active liquid agitator.

With the development of technology, the size of electronic products is getting smaller and smaller, and their precision is getting higher and higher. The automatic dispensing machine is an automated equipment developed for the packaging industry, which realizes the packaging of the product by controlling the colloid to drip or coat the colloid on the workpiece. It is also called a glue dispenser or a glue spreader. With the development of industrialization, automatic dispensers have reduced the use of human resources, which has eased the shortage of manpower to a certain extent. At this stage, dispensers have been widely used in all walks of life, and are more indispensable packaging equipment in the electronics industry.

Two-component glue can effectively control the hardening time and improve the accuracy of dispensing. Therefore, the current application fields are becoming more and more extensive. In order to fully mix the original two-liquid and obtain the complete performance of the colloid, a high-performance liquid agitator is necessary.

However, the most commonly used agitators in dispensers currently use passive agitation. This type of passive agitator uses pressure to push the liquid colloid to mix in the agitator. Although the structure is simple, the uniformity of mixing is usually insufficient. . Therefore, in order to be able to mix colloids more fully, the pushing pressure required is also increasing.

Therefore, how to improve the uniformity of the colloid mixed by the agitator while reducing the pressure of the liquid colloid is really helpful to improve the quality and production efficiency of the glued parts.
