Automatic weighing device for traditional Chinese medicine decoction pieces

Abstract

The invention relates to an automatic weighing device for traditional Chinese medicine decoction pieces. The automatic weighing device comprises impellers and a driving motor which are horizontally placed; the upper portions of the impellers are partially blocked; a base plate horizontally fixed is arranged below the impellers; an opening is formed in the base plate; the opening is located below ablocking piece; a weighing hopper is further arranged below the opening; one side of the weighing hopper is fixed onto a weighing sensor; the weighing sensor is fixed onto a device structural body; the bottom part of the weighing hopper is provided with a movable door; the movable door is provided with a stop plate; a door opening motor is further fixed onto the device structural body; a shaft ofthe door opening motor is provided with a shifting block; a controller is further arranged in the device; under the control of the controller, a medicine material enters from parts, not blocked, of the upper portions of the impellers, is driven by the impellers rotating, falls from the position of the opening in the base plate, and enters the weighing hopper; the weight of the medicine material in the weighing hopper is measured in real time by the controller, and the speed of the driving motor for the impellers is controlled; when the weight of the medicine material reaches or approaches toa preset target value, the impellers stop rotating; the door opening motor is started, and the stop plate on the movable door is shifted by the shifting block, so that the movable door is opened, andthe medicine material in the weighing hopper is delivered out; and the controller of the device is connected with a dispensing system through an industry network, receives a control command from the dispensing system, and executes tasks of weighing and medicine delivery.
