[0002] The tension spring type discharging device is usually composed of a silo, a discharging port, a tension spring and a control mechanism. When the material in the silo reaches a certain weight or pressure, it will overcome the tension of the tension spring, causing the discharging port to open and the material to be discharged. After the material is discharged, the weight or pressure in the silo decreases, and the tension of the tension spring closes the discharging port, thereby achieving control over the discharging.

For some production processes that require extremely high discharge accuracy, it may not be able to meet the needs. For this reason, we propose a tension spring type discharge device.
