Pouring system capable of automatically controlling net content of square brown sugar

The invention discloses a pouring system capable of automatically controlling the net content of square brown sugar. The pouring system comprises a pouring machine, a first conveying belt, a mold plate, a first photoelectric sensor, a cooling mechanism, a demolding mechanism, a second photoelectric sensor, an arc-shaped baffle, a second conveying belt, a guide column, a third photoelectric sensor,a sugar grabbing mechanism, a weighing device and a controller, wherein the sugar grabbing mechanism and the weighing device are used for automatically grabbing and measuring the demolded square brown sugar; then, the plunger stroke of a plunger type pouring machine is automatically adjusted according to an error of the net content, and the error of the net content of the square brown sugar is controlled within an allowable range, so as to automatically monitor the net content of the square brown sugar by the square brown sugar pouring system. The pouring system solves the problem of low efficiency and automation deg
