An automatic weighing device for cotton which is researched and fabricated can be implement in cotton processing production line. This device mainly includes transmission device

weighing device and bracket.Transmitting device consists of drive motor

transmission shaft and conveyor belt. Weighing devices takes two weighing sensors as measuring element so as to realize weighing combined with measurement and control circuit.The sensor is independently researched and fabricated

which can ensure precision of 0. 05 %. The circuit uses ADS1240 as core

which realizes signal filtering and amplification. 4 # section bar is used to weld pillow block bearing

which supports and connects each parts of device.
