Automatic metal removing mechanism for Chinese herbal medicine screening machine

Abstract

The invention discloses an automatic metal removing mechanism of a traditional Chinese medicinal material screening machine, which comprises a conveyor belt, a rotating shaft, a motor, a pillar, a first detection mechanism, a coil, an alarm, an alarm light, a rejecting mechanism, a rejecting box, a baffle, a pole, A distance sensor, a second detection mechanism, a cylinder, a push rod, a rejecting plate, a main drive wheel, an auxiliary drive wheel, a bracket and an electric push rod. The metal automatic removal mechanism of the Chinese medicinal material screening machine of the present invention has changed the traditional detection and removal method, adopts the conveyor belt to convey the detection and removal, and adjusts the rotation speed of the conveyor belt through the motor, which can make the Chinese medicinal materials flow smoothly and improve the accuracy of the detection during the metal detection process. The rate is high, and the unqualified products are alarmed in time; the rejecting mechanism is equipped with a distance sensor and a rejecting confirmer, which can judge the position of unqualified products in Chinese herbal medicines and remove them in time, and ensure the rejecting rate and the pass rate of the product. Good economic and production benefits, suitable for popularization and use.

Description

technical field [0001] The invention relates to a rejecting mechanism, in particular to a metal automatic removing mechanism of a screening machine for Chinese herbal medicines, and belongs to the technical field of screening equipment for Chinese medicinal materials. Background technique [0002] Chinese medicinal materials refer to medicinal materials produced in a region with specific natural conditions and ecological environment; in the processing and production of Chinese medicinal materials, metal foreign matter and metal powder may be mixed in Chinese medicinal materials, which affects the quality of Chinese medicinal materials, and even affect the user's health. [0003] In the prior art, the metal removal method used in the screening of Chinese herbal medicines is the drop type. This method of removal is relatively high in terms of detection and removal costs, and the rejection rate is low. Since the falling speed of Chinese medicinal materials cannot be stably cont...

Problems solved by technology

[0003] In the prior art, the metal removal method used in the screening of Chinese herbal medicines is the drop type. This method of removal is relatively high in terms of detection and removal costs, and the rejection rate is low. Since the falling speed of Chinese medicinal materials cannot be stably controlled , it is not convenient to remove metal-containing Chinese herbal medicines
