Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a raw material metering and statistical scale. Background Art

[0002] A hopper scale is a type of metrological and statistical scale. Its structure mainly includes a hopper, a gravity sensor, a material gate, a material gate drive device and a control system. The hopper is set on the gravity sensor, the material gate drive device is installed on the hopper, and the material gate is set at the discharge port of the hopper. The switch is controlled by the material gate drive device. When the gravity detected by the gravity sensor reaches a preset value, the control system will control the feeding device to stop feeding, and at the same time control the material door driving device to open the material door for discharging. This type of hopper scale has the advantages of simple structure and easy operation, but still has the following defects: First, the existing hopper scale generally adopts a hinged material door designed at the discharge port, and uses a cylinder to control the material door to rotate and open, and the inside of the hopper is designed to be an inclined surface to facilitate the sliding of materials, but the rotation and opening of the material door requires sufficient avoidance space, so it is not suitable for places with small spaces, and the hopper with an inclined surface will cause the volume of the hopper to decrease. In order to obtain sufficient volume, the volume of the hopper needs to be increased, but this will further increase the space occupied by the hopper; second, the existing hopper scale will stop feeding after the weight of the material in the hopper reaches a preset value, and then open the material door of the hopper for discharging, which will cause the weighing process to be interrupted, and continuous operation cannot be carried out, which is not conducive to improving weighing efficiency.

[0010] The utility model provides a raw material metering and statistical scale, which has the advantages that: the utility model cancels the existing material door design, and controls the discharge of the hopper by adding a transmittable material blocking belt on the hopper, which not only does not require avoidance space, but also does not require a material dropping inclined surface, so it is more suitable for narrow spaces and has a larger available volume than existing hoppers of the same volume. The utility model passes the material blocking belt horizontally through the hopper, so that the hopper can still carry out material adding operations during the discharge process, thereby ensuring the continuity of the weighing process and improving the weighing efficiency.
