Detailed ways

The technical solutions in the embodiments of the present utility model will be described clearly and completely in combination with the implementation of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

In the embodiment of the utility model, a weighing mixer with adjustable discharge capacity includes a mixing shell 1, a top cover 2 is installed on the upper side of the mixing shell 1, and a bolt is passed through the upper middle of the top cover 2 A stirring motor 3 is installed to provide stirring power. The lower side of the stirring motor 3 is equipped with a rotating shaft 4, and the lower side of the rotating shaft 4 is equipped with a stirring blade 5. The stirring motor 3 drives the stirring blade 5 to rotate at a high speed to mix the materials. The top cover 2 A vacuum feeder 8 is installed on the upper side, and a plug-in valve 9 is installed on the inlet of the mixing shell 1 on the lower side of the vacuum feeder 8. The size of the plug-in valve 9 is adjusted to control the cutting speed. The larger the adjustment of the plate valve 9 is, the faster the discharge speed, and the smaller the adjustment of the inserting plate, 9, the lower the discharge speed. The side of the vacuum feeder 8 is connected to the raw material hopper 6 through the suction pipe 17, and the raw material hopper 6 and the vacuum feeder 8 are matched with at least three pairs to meet the mixing ratio of a variety of powder and granular materials. A platform scale 7 is installed on the lower side of the raw material hopper 6, and a weighing sensor is installed inside the platform scale 7 to detect the raw material hopper 6 The weight of the powder and granular material in the mixing shell 1 is convenient for accurate proportioning. The lower side of the mixing shell 1 is welded with a bracket 11, and a PLC control cabinet 12 is installed on the side of the bracket 11, and the stirring motor 3, the vacuum feeder 8 and the insert The plate valve 9 is electrically connected to the PLC control cabinet 12, which is convenient for overall control. The lower side of the mixing shell 1 is equipped with a discharge port 13, and the lower side of the discharge port 13 is installed with a butterfly valve 14 in the middle of the lower side to facilitate the control of the mixed material. discharge;

There are feet on the underside of the raw material hopper 6, and pulleys on the underside of the feet;

The plug-in valve 9 is composed of a valve seat 901, a connecting seat 902, a plug-in plate 903, a telescopic rod 904, and a cylinder 905. The connecting seat 902 is installed on the side of the valve seat 901, and the valve seat 901 and the connecting seat 902 are provided with sliding grooves.
