Description

Technical Field

[0001] The present invention relates to a liquid agitator, and more particularly to an active liquid agitator. Background Art

[0002] With the advancement of technology, electronic products are becoming increasingly smaller and more sophisticated. Automatic dispensing machines, also known as glue dispensers or coating machines, are a type of automated equipment developed specifically for the packaging industry. They control the colloid by applying it to workpieces or products, achieving product packaging. With the advancement of industrialization, automatic dispensing machines have reduced the use of human resources, alleviating labor shortages to a certain extent. Currently, dispensing machines are widely used across various industries and are an indispensable packaging device for the electronics industry.

[0003] Two-liquid mixed adhesives can effectively control the curing time and improve dispensing accuracy, so their current application areas are becoming increasingly widespread. In order to fully mix the original two liquids and obtain the full performance of the colloid, a high-efficiency liquid agitator is necessary.

[0004] However, the agitators commonly used in current dispensing machines mostly employ passive mixing. These passive agitators use pressure to push the liquid colloid into the agitator to mix it. While simple in structure, the mixing uniformity is often insufficient. Therefore, to achieve more thorough mixing, the required pushing pressure is increasing.

[0005] Therefore, how to improve the uniformity of the colloid mixed by the agitator and reduce the pressure of the liquid colloid will help improve the quality and production efficiency of the bonded parts. Summary of the Invention

[0006] This summary is intended to provide a simplified summary of the present disclosure so that readers can have a basic understanding of the present disclosure. This summary is not a complete overview of the present disclosure and is not intended to identify important / critical elements of the present invention or to define the scope of the present invention.

[0007] One object of the present invention is to provide an active liquid agitator to improve the uniformity and efficiency of liquid mixing.

[0008] To achieve the above objectives, one technical aspect of the present invention relates to an active liquid agitator comprising an outer cylinder, a first spiral, a stirring rod, and a second spiral. The outer cylinder has a mixing chamber, the first spiral is fixed to the mixing chamber, and the stirring rod is disposed within the mixing chamber and can actively move up and down within the mixing chamber. Furthermore, the second spiral is fixed to the stirring rod and moves up and down with the stirring rod.

[0009] In some embodiments, the first spiral and the second spiral each comprise a spiral wire.

[0010] In some embodiments, the outer cylinder includes a cylinder body, a fixing flange connected to the cylinder body, and a connecting portion connected to the fixing flange.

[0011] In some embodiments, the connecting portion includes an inlet connected to the mixing chamber, and the inlet is used to receive two or more liquids into the mixing chamber for mixing.

[0012] In some embodiments, the stirring rod includes a shaft, and the second spiral is disposed on a surface of the shaft, and the shaft has a hemispherical end surface.

[0013] In some embodiments, the outer cylinder further includes a tapered surface for tightly fitting with the hemispherical end surface of the shaft.

[0014] In some embodiments, the outer tube further includes a nozzle formed at the top of the conical surface for outputting the mixed liquid.

[0015] Therefore, the active liquid agitator can utilize the relative motion of the two helices to effectively mix two or more liquids, and propel the liquid through the spiral mixing structure, so that it moves from the inlet to the nozzle. Compared with the passive agitator, it can effectively reduce the pressure required to push the liquid and further improve the uniformity of the mixed liquid, thereby enhancing the quality and efficiency of dispensing.
