Description

Technical Field

[0001] The utility model relates to the technical field of refined wax production, in particular to a highly applicable powder spraying device for modulating refined wax. Background Art

[0002] In the production of refined wax, the wax injection machine is used to make wax molds. When in use, the mold is first evacuated to a vacuum, and then the wax is injected into the mold. After the wax solidifies, the wax mold is taken out. Before injecting the wax liquid, it is often necessary to spray powder into the mold cavity. The invention patent application with application number 201811524957.0 discloses a quantitative powder spraying and wax injection integrated assembly, including a powder feeding mechanism and a composite feeding nozzle mechanism. The composite feeding nozzle mechanism includes a powder spraying head and a wax liquid feeding nozzle. One end of the wax liquid feeding nozzle extends into the powder spraying head. A vacuum tube one-way valve is provided on the powder spraying head, and a wax liquid tube one-way valve is provided on the wax liquid feeding nozzle. The powder feeding mechanism includes two silo parts and two connecting plates. The two silo parts are fixed to the powder spraying head. The two silo parts are respectively provided with concave surfaces on the opposite sides. A quantitative material distribution roller is provided between the two concave surfaces. The quantitative material distribution roller is abutted against the concave surface, and the quantitative material distribution roller is provided with a powder storage tank.

[0003] The above technical solution combines the powder spraying process with the wax injection process, and realizes the quantitative feeding of powder through the quantitative distribution roller, so as to avoid uneven powder spraying in the mold caused by manual powder spraying and improve the qualified rate of wax mold forming. However, the amount of powder sprayed each time is fixed and cannot be adjusted according to different molds. The applicability is limited. Therefore, based on the above technical problems, it needs to be improved. Utility Model Content

At this time, the slide bar slides in the slide groove and drives the adjustable bottom plate to move radially along the feed roller through the connecting rod, thereby realizing the position adjustment of the adjustable bottom plate, and then realizing the adjustment of the powder storage space in the powder storage tank. After the adjustment is completed, the adjusting shaft and the feed roller are fixedly connected by the connecting bolts again.

[0012] The utility model also includes other components that can make a highly applicable modulated refined wax powder spraying device normally used, which are all conventional technical means in the art. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the art.
