[0014] (III) Beneficial effects
[0015] Compared with the prior art, the utility model provides a weighing controller, which has the following beneficial effects:
[0016] 1. The weighing controller is provided with a feeding component. The rice is placed in the feeding hopper and then fed into the weighing bin. When the electric push rod controls the adjusting plug to be away from the upper end of the middle bin, the feeding is relatively rapid. When it is gradually approached to the upper end of the middle bin, the feeding will gradually slow down until the feeding is completely closed. In this way, when quantitatively weighing the rice, the rice is first completely fed to quickly form a certain weight. When the weight is close to the weight to be quantitatively determined, the feeding speed begins to slow down until the closer it is to the specified weight, the slower the feeding speed. In this way, the feeding amount can be reduced in a uniform linear manner, and a more accurate effect can be achieved when quantitatively determining the weight.
[0017] 2. The weighing controller is provided with a handle, a motor and a scraper. The handle can drive the slide plate and the entire feeding assembly to move. When feeding, the rice can fill the entire feeding hopper. Then the swing of the motor can always swing back and forth to feed. When the slide plate moves, the paddle can also flatten the arched rice, which can further improve the accuracy of subsequent weighing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the related art, the feeding speed of rice is very fast, so that the weighing device of the weighing and packaging device cannot display the weighed weight in time, resulting in inaccurate weighing results. When it is necessary to weigh the rice quantitatively, it is difficult to control the precise feeding amount, and the uneven distribution of rice in the weighing frame will also affect the final weighing accuracy.
[0028] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a weighing controller. When it is needed, the rice only needs to be placed in the discharge hopper 301, and then used to discharge the rice into the weighing bin 1. When the electric push rod 306 controls the adjusting plug 307 to move away from the upper end of the intermediate bin 302, the discharge is relatively rapid, and when it is gradually moved closer to the upper end of the intermediate bin 302, the discharge will gradually slow down until the discharge is completely closed. When discharging the rice, the handle 5 can drive the slide plate 4 and the entire discharging assembly 3 to move, and the swing of the motor 7 can always achieve reciprocating left and right swinging for discharging the rice. The paddle 6 can also flatten the arched rice. When the weight is close to the weight required for quantitative measurement, the discharging speed begins to slow down until the closer it is to the limited weight, the slower the discharging speed.
