Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. It can be seen that the described implementation examples replace the embodiments of the present invention, rather than all the embodiments. The embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without attempting to carry out labor reforms, fall within the protection scope of the present invention.

, A Gravimetric blender with adjustable discharge capacity, comprising a blending shell 1, a top cover 2 is installed on the upper side of the blending shell 1, and a blending motor 3 is installed on the upper middle of the top cover 2 through bolts, It is used to provide blending power. The lower side of the blending motor 3 is equipped with a rotating shaft 4, and the lower side of the rotating shaft 4 is installed with a blending blade 5. The blending motor 3 drives the blending blade 5 to rotate at a high speed to mix the materials. The upper end of the top cover 2 is equipped with vacuum feeding Machine 8, the lower side of the vacuum feeder 8 is equipped with a plug-in valve 9 on the inlet of the blending shell 1, and the size of the plug-in valve 9 is adjusted to control the cutting speed. The greater the adjustment of the plug-in valve 9, The faster the feeding speed, the smaller the adjustment of the board, 9 and the lower the feeding speed. The vacuum feeder 8 frequency converter is connected to the raw material hopper 6 through the suction pipe 17, and the raw material hopper 6 is matched with the vacuum feeder 8 At least three pairs are provided to meet the blending 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 weight of the powder and granular materials in the raw material hopper 6, The weight is appropriately proportioned.
