Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, and in particular relates to a weighing quantitative feeding device. Background Art

[0002] A conveyor-type weighing scale is a device used to weigh and discharge materials. It generally includes a hopper with a feed port, a barrel connected to the bottom of the hopper, and a weighing sensor disposed at the bottom of the hopper. Materials are fed into the barrel through the feed port of the hopper, and discharged outward through a screw disposed in the barrel. At the same time, the weighing sensor disposed at the bottom of the hopper measures the weight of the materials. However, the existing conveyor-type weighing scale cannot effectively control the discharge flow rate of the materials, nor can it control the speed of the materials being discharged, which results in poor weighing accuracy and control precision.

[0003] The patent publication number CN220536971U discloses a weighing bucket quantitative feeding device, including a bottom silo, the bottom of the silo is connected to a spherical silo, a discharging screw feeder is connected to the bottom of the spherical silo, and the discharging screw feeder is fixed on a weighing platform; the discharging screw feeder is connected to a servo motor through a transmission mechanism, and the servo motor is electrically connected to a controller. The utility model uses a static weighing sensor to weigh and detect the weight measured in the silo. When the silo is full, the static weighing sensor can weigh the weight of each discharge and transmit it to the control panel of the control display box, and then the servo motor controls the rotation of the discharging screw to accurately feed the material.

[0004] However, when the material in the spherical bucket of the equipment reaches the lower limit of weighing, the discharging screw feeder fixes the discharging amount according to the rotation speed at that time, and at the same time controls the material in the silo to quickly drop into the spherical bucket. It is impossible to determine whether the material in the spherical bucket has reached the lower limit of weighing. Therefore, the spherical bucket cannot be relied on to further improve the weighing accuracy and control precision. In addition, the equipment structure is complex and it is not convenient for subsequent maintenance and repair. Utility Model Content
