The utility model has the advantages that:
the inner cavity of the weighing hopper is provided with a suspension ball for closing or opening the outlet of the weighing hopper, the suspension ball is suspended at the front end of the lever plate, and the rear end of the lever plate is connected with a power device; when a product processed in real time enters the weighing hopper, the weighing sensor measures the weight in real time, when the weight reaches a set weight value, the product processed in real time stops entering, the power device pulls the rear end of the lever plate to enable the lever to pull up the suspension ball, the suspension ball is separated from the outlet of the weighing hopper, the outlet of the weighing hopper is opened, and the product flows out; the product has the advantages of simple structure, large measuring range, low manufacturing cost and convenient use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is an exploded schematic view of the present invention;
fig. 2 is a schematic cross-sectional view of the present invention;
fig. 3 is a schematic diagram of the present invention showing a cross section partially enlarged.
Detailed Description
Referring to fig. 1 and 2, the weighing hopper with the outlet automatically opened and closed comprises a weighing hopper 1, wherein the weighing hopper 1 is fixed on a weighing sensor 8, and the weighing sensor 8 adopts a resistance strain gauge type; the inside of the weighing hopper 1 is provided with a suspension ball 2 for closing or opening the outlet of the weighing hopper 1, and the opening diameter of the outlet of the weighing hopper 1 and the suspension ball 2 matched with each other are selected according to different products; the suspension ball 2 is suspended at the front end of the lever plate 3, and the rear end of the lever plate 3 is pulled by the power device 4; when the device works, a product processed in real time enters the measuring hopper 1, the weighing sensor 8 measures the weight in real time, when the weight value reaches a set weight value, the product processed in real time stops entering, the power device 4 pulls the rear end of the lever plate 3 to enable the lever to pull the suspension ball 2 upwards, the suspension ball 2 leaves the outlet of the measuring hopper 1, the outlet of the measuring hopper 1 is opened, and the product flows out; the product has the advantages of simple structure, large measuring range, low manufacturing cost and convenient use.
Referring to fig. 3, a fixed support plate 5 is movably mounted at a fulcrum of a lever plate 3, the fixed support plate 5 is fixed on the inner side wall of a weighing hopper 1, a rotating block 7 is mounted on a power device 4, the rotating block 7 is connected with the rear end of the lever plate 3 through a hinge 6, when a weight value measured by a weighing sensor 8 reaches a set value, the power device 4 starts to rotate the rotating block 7, and the rotating block 7 pulls the rear end of the lever plate 3 downwards through the hinge 6, so that a suspension ball 2 is separated from an outlet of the weighing hopper 1; the power unit 4 can rotate the rotary block 7 by a motor, a pulley, a sprocket, or the like.
Fixed extension board 5 is including being fixed in fixed plate 51 on the internal side wall of weighing hopper 1, with lever plate 3 fulcrum swing joint's fulcrum plate 52, fulcrum plate 52 cartridge is on fixed plate 51, makes to form crisscross setting between fulcrum plate 52 and fixed plate 51, makes the face of fixed plate 51 can paste tightly fixedly with weighing hopper 1 internal side wall, and the face of fulcrum plate 52 then can keep the state of pasting tightly with the lateral wall of lever plate 3, increases the stability of the installation of lever plate 3.
