[0027] The usage method of this embodiment is as follows: pour the biscuits to be packaged into the conical biscuit storage box 2, pre-set the starting weight value of the servo motor 5 according to the packaging weight requirement using the PLC controller 6, and set the servo motor 5 to start half a circle each time, start the small vibration motor 17 to vibrate and transmit a hard shock force to the conical biscuit storage box 2 to assist the biscuits in the conical biscuit storage box 2 to fall down better, and the biscuits fall into the right side of the stopper 8 through the discharge tube 15, the elastic rubber ring 16 and the feeding hole 14 on the right side in turn, and the weighing sensor 12 weighs the biscuits entering the right side of the stopper 8 through the weighing pan 11 and transmits the weight value to the PLC controller 6. When the preset weight value is reached, the PLC controller 6 controls the servo motor 5 to start half a circle, the servo motor 5 drives the rotating shaft 4 to rotate half a circle, the rotating shaft 4 drives the turntable 13 to rotate half a circle, and the turntable 13 drives the two feeding holes 14 to rotate and exchange positions. When the feeding tube 15 is staggered, the turntable 13 will temporarily block the feeding tube 15 at the bottom until the feeding hole 14 on the left rotates to the right for alignment and connection. When the rotating shaft 4 rotates, the two stopper sleeves 8 are driven to rotate and exchange positions through the two connecting rods 7. When the stopper sleeve 8 on the right rotates to the left, the biscuits are driven to rotate to the left position. At this time, the biscuits are discharged downwardly by the discharge hole 9 onto the belt conveyor 100 for transportation. At this time, the biscuits continue to fall downward into the stopper sleeve 8 rotated to the right and are weighed again. When the preset weight value is reached, the discharge and feeding operations are switched again. By analogy, the effect of accurately separating the piles of biscuits by weight is achieved, so as to facilitate the accurate packaging of the biscuits by the personnel at the rear of the belt conveyor 100. The method of separating the biscuits into piles of the same weight by weighing is not affected by the shape or tilt of the biscuits, which is convenient for accurate packaging of biscuits of different shapes and improves applicability.

[0028] In addition, since the weighing pan 11 itself has a certain weight, when the PLC controller 6 is used to set the control start weight value, the weight value can be set to the total weight of the weighing pan 11 and the biscuits to be packaged, so that the biscuits discharged are of the required weight.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
