Description

Technical Field

[0001] The utility model relates to a mixing cylinder, in particular to a multi-purpose powder mixing cylinder. Background Art

[0002] Stirring is required during the production and filling of welding powder, and conventional welding powder mixing barrels generally use conventional simple stirring shafts for mechanical stirring. However, this conventional stirring device is not only difficult to fully mix the various components in the welding powder, but also due to the characteristics of welding powder, during the stirring process, due to external environmental factors, the welding powder is very likely to be damp and affect the use. At the same time, the welding powder is also prone to caking and accumulation due to moisture, which reduces the mixing effect of the welding powder. Conventional drying devices are very likely to burn due to the combustion aid inside the welding powder, affecting the safety of welding powder drying. At the same time, conventional welding powder mixing barrels can only be exported once after the welding powder is fully mixed. During filling, it can only be weighed by other devices, and the welding powder content cannot be accurately discharged, affecting the processing convenience of welding powder production.
