The differential mechanism 1, the weighing mechanism 2, the discharging mechanism 3 and the boxing mechanism 4 are sequentially connected to the support 5 and are controlled and coordinated through the controller, so that a complete conveying mechanism for arranging the flexible bagged materials is formed. The automatic separating and conveying, automatic weighing, automatic discharging and automatic boxing of the flexible bagged material tidying product before final boxing are realized, and when the automatic bagged material tidying device is matched with an automatic production line for use, the production efficiency and the production quality can be obviously improved.

In order to automatically separate the products 6 to be boxed to form individually conveyed products, which facilitates later weighing and boxing, in this example, four conveyor belts 7 connected in sequence are included in the differential mechanism 1, and each conveyor belt 7 is driven by a motor 11, a differential belt 12, a large chain wheel 13 and a small chain wheel 14 to form step-by-step speed-increasing conveying, so that the products 6 to be boxed on the upper conveyor belt are subjected to acceleration conveying when entering the lower faster conveyor belt, and the products 6 to be boxed which first contact the lower conveyor belt are separated from the products which later contact the lower conveyor belt, so that the products 6 to be boxed which are stacked on the conveyor belts 7 are separated one by one in the four-stage conveying process, and the automatic separation process is completed.

In order to further increase the reliability and effectiveness of the separation process, an ejector mechanism 8 is provided in this example below the mouth of each sequentially connected conveyor belt 7. The ejection mechanism 8 is used for separating the products to be boxed 6 which are mutually overlapped or lapped on the conveyor belts 7 under the action of human intervention, so that the conveyor belts 7 at all levels can be further quickly and stably separated. The ejection mechanism 8 comprises an air cylinder 21 fixed on the support 5, a top plate 22 connected to the cylinder rod of the air cylinder, and an electric eye 9 for detecting the length of the product 6 to be boxed on the conveyor belt 7. The top end of the top plate 22 is provided with a rubber pad 23, and the rubber pad 23 can slow down collision damage to the product 6 to be boxed in the ejection process. The electric eye 9 corresponds to the tail end of a higher-level conveyor belt on one side of the connecting port, the electric eye 9 can detect the length of the products 6 to be boxed on the conveyor belt 7 at any time, when the length of the products exceeds the length requirement, the controller controls the air cylinder 21 to work, the top plate 22 moves upwards, the products 6 to be boxed exceeding the length requirement are jacked up, therefore, the products 6 to be boxed are overlapped or lapped to be mutually scattered, and the final one-by-one conveying process is completed under the conveying of the sequentially connected speed-increasing conveyor belts 7.

The weighing mechanism 2 is used for carrying out online weighing on the products 6 to be boxed after differential transmission and online detection on weighing results, and feeding the detection results back to the controller to form action control of the controller on the discharging mechanism 3. The weighing mechanism 2 is positioned at the tail ends of four sequentially connected conveying belts 7, an annular conveying belt 15 which is driven by a synchronous motor 18 and conveys in the horizontal direction is arranged at the top of the weighing mechanism 2, the annular conveying belt 15 corresponds to the output ends of the sequentially connected conveying belts 7 in the differential mechanism 1, the lower part of the annular conveying belt 15 is fixed on a weighing sensor 17 through a supporting block 16, and the weighing sensor 17 is fixed on the support 5. The weighing sensor 17 can automatically weigh the products 6 to be boxed falling onto the endless conveyor belt 15 in the conveying process, and corresponding results are obtained and fed back to the controller by comparing whether the weight of the products 6 to be boxed is one unit.

In order to further ensure the uniqueness of the products 6 to be boxed, which are sent out by the weighing mechanism 2, and meet the actual production requirements. In this case, a photoelectric switch 19 is also provided on the weighing means 2, which photoelectric switch 19 is fixed to the support 5, the photoelectric switch 19 corresponding to the input end of the endless conveyor 15.
