The arranged connecting assembly 9 is used to connect the fixing plate 6 and the cylinder 5, and at the same time, the fixing plate 6 rotates at the output end of the cylinder 5. Thus, during the use process, the cylinder 5 drives the hopper door 4 to rotate at the bottom of the weighing hopper 3 to complete the opening and closing of the discharge port of the weighing hopper 3. The cross-section of the arranged fixing plate 6 is triangular.

[0021] Specifically, the feeding assembly 7 includes a moving frame 701 arranged on one side of the workbench 1. A first vibrating plate 702 is fixedly connected to the top end of the moving frame 701. A second vibrating plate 703 is fixedly connected to the top end of the moving frame 701 and on one side of the first vibrating plate 702.

[0022] It should be noted that the arranged moving frame 701 is used to fix the positions of the first vibrating plate 702 and the second vibrating plate 703. The support legs of the first vibrating plate 702 and the second vibrating plate 703 are connected and fixed to the top surface of the moving frame 701 by bolts. Both the first vibrating plate 702 and the second vibrating plate 703 are feeding plates of model BY-JD.

[0023] Furthermore, when weighing the materials, first, 80% to 90% of the materials are directly conveyed into the weighing hopper 3 through the first vibrating plate 702, then the specific weight of the materials is measured by the weighing assembly, and then the materials are conveyed into the weighing hopper 3 one by one through the second vibrating plate 703 until the required weight is completed. Through this design, the weight of the packaged materials is accurately controlled.

[0024] Specifically, the connecting assembly 9 includes a connecting block 901 fixedly connected to the output end of the cylinder 5, a connecting groove 902 is provided at the bottom of the connecting block 901, a fixing plate 6 is inserted and connected inside the connecting groove 902, sliders 903 are symmetrically fixedly connected on both sides of the fixing plate 6, sliding grooves 904 are symmetrically provided on the inner walls on both sides of the connecting groove 902, the slider 903 is inserted and connected inside the sliding groove 904, a positioning bolt 905 is inserted and connected on one side of the connecting block 901, the positioning bolt 905 is inserted and connected in the middle of the slider 903, the positioning bolt 905 is inserted and connected in the end of the fixing plate 6, and a positioning nut 906 is provided on the middle thread sleeve of the positioning bolt 905.

[0025] It should be noted that the setting connection block 901 is fixedly connected to the output end of the cylinder 5 by welding, and the connection groove 902 opened at the bottom end of the connection block 901 is used for the fixing plate 6 to penetrate the bottom of the connection block 901.
