Description

Technical Field

[0001] The utility model relates to the technical field of tin powder mixers, in particular to a tin powder mixer with a screening function. Background Art

[0002] The tin powder mixer uses high-speed stirring blades to separate the tin powder and solvent, ensuring the dispersion of the tin powder and achieving a more perfect printing and reflow soldering effect. On the basis of replacing manual stirring, it greatly improves work efficiency and work quality.

[0003] For example, publication number CN213528268U discloses a solder paste stirring device, including a stirring barrel, a cover, a solenoid valve, a stirring device, a feeding device and a storage and cleaning device. The stirring device is arranged in the stirring barrel, the feeding device and the storage and cleaning device are symmetrically arranged on the outer wall of the stirring barrel, the cover is arranged on the top of the stirring barrel, and the solenoid valve is fixed on the bottom of the stirring barrel. The tin powder mixer can make each sub-gear stable by arranging the outer teeth of each sub-gear in the groove, and the stirring device can stir more evenly and quickly. After the stirring is completed, The solder paste is taken out by opening the solenoid valve, and the cleaning agent in the storage and cleaning device is opened to enter the mixing barrel to prevent the solder paste from hardening after a long time. If it is not cleaned in time, it will accumulate after a long time, which is very troublesome to clean and causes unnecessary damage. However, there are other shortcomings when using the tin powder mixer. First of all, before stirring the tin powder, the tin powder mixer needs to perform some basic screening treatment on the tin powder manually, which is time-consuming and manpower-consuming. As a result, the tin powder mixer does not have the effect of screening and stirring the tin powder. Therefore, there are still certain shortcomings when using the device. Utility Model Content
