Description

Technical Field

[0001] The utility model relates to the field of raw material metering bins, in particular to a material discharging mechanism for raw material metering bins. Background Art

[0002] The weighing bin is a measuring instrument used for trade settlement and must comply with national standards. Since it is an electronic scale assembled on site from purchased components and self-made parts, standard weight calibration must be carried out at any weighing section of the full scale, and the raw materials need to be discharged through the discharge mechanism after being measured.

[0003] According to a Chinese patent with publication number CN217845351U, a discharge mechanism for a raw material metering bin is disclosed. The utility model enables the material to fall completely through the inclined surface on the top of the metering plate, thereby achieving the purpose of complete convenience. In conjunction with a reset spring, since the reset tension of the reset spring is greater than the total gravity of the metering plate and the connecting rod, it can drive the metering plate and the connecting rod to move upward, thereby achieving the reset effect. During the reset process, it can also play a vibrating role, thereby improving the efficiency of material discharge.

[0004] With regard to the above-disclosed patent content, a metering plate and a connecting rod are provided so that the raw materials fall onto the metering plate for weighing, and then the metering plate is moved downward after weighing. At this time, the raw materials will slide from the metering plate to the lower part of the inside of the metering box, and then be discharged through the discharge pipe. Although this method can weigh and discharge the raw materials, a small amount of the raw materials may adhere to the metering plate and be difficult to clean and fall downward, so that the weighed raw materials cannot be completely discharged, thereby reducing the discharge efficiency of the raw materials.
