[0027] The surface of the pushing plate 10 is provided with a material stacking assembly for preventing the material from falling out of the open rectangular port 9 and the discharge port 6, the material stacking assembly comprises a first stacking plate 16 fixedly installed on one side of the pushing plate 10 and two second stacking plates 17 located on the other side of the pushing plate 10, the surface of the pushing plate 10 is symmetrically provided with rotating ports, rotating rods 18 are rotatably installed in the rotating ports, the two second stacking plates 17 are fixedly connected to one end of the two rotating rods 18, respectively, threaded grooves 19 are formed in the other end of the rotating rods 18 away from the second stacking plates 17, threaded rods 20 are threadedly installed in the threaded grooves 19, the threaded directions of the two threaded rods 20 are opposite, one end of the threaded rods 20 is connected to the groove wall of the threaded groove 19 through an expansion component, the expansion component comprises an expansion spring 21, the two ends of the expansion spring 21 are fixedly connected to one end of the threaded rod 20 and the groove wall of the threaded groove 19, respectively, the threaded rod 20 is limited from rotating through a limiting component, the limiting component comprises an installation plate 22 fixedly installed on one end of the threaded rod 20, the surface of the pushing plate 10 is symmetrically provided with slide rods 23, the two installation plates 22 are slidably sleeved on the two slide rods 23, respectively, the two threaded rods 20 are controlled from rotating relative to each other through a pressing component, the pressing component comprises two L-shaped pressing plates 24 fixedly installed on one side of the machine body 1, and the two pressing plates 24 correspond to the positions of the two installation plates 22, respectively.
[0028] In the initial state, the first stack plate 16 is located outside the machine body 1, the ends of the two threaded rods 20 are respectively abutted against the two abutment plates 24, the telescopic spring 21 is in the contracted state, and the two second stack plates 17 are in the symmetrical inclined state. The material falling from the hollow column 2 falls through the gap between the two second stack plates 17 and then falls on the upper surface of the weighing plate 8. When the weight of the material measured by the weighing sensor 7 reaches the set value, the output shaft of the driving motor 13 is controlled to rotate forward. At this time, the first stack plate 16 gradually moves into the machine body 1 along with the movement of the pushing plate 10, and the two second stack plates 17 gradually extend from the discharge port 6. In the extending process, the abutting pressure force provided by the abutment plate 24 to the threaded rod 20 gradually decreases and disappears, and the threaded rod 20 moves back to the original position under the elastic potential of the telescopic spring 21. Since the threaded rod 20 cannot rotate, the two mounting rods 18 relatively rotate with the two second stack plates 17 under the cooperation of the threads, and the two second stack plates 17 rotate to the parallel state.
[0029] After the material is pushed out of the discharge port 6 by the pushing plate 10, the output shaft of the driving motor 13 is controlled to rotate reversely by the weighing sensor 7. At this time, the baffle 5 also moves to no longer cover the bottom of the hollow column 2. The material in the feeding hopper 3 falls from the bottom opening of the hollow column 2 and falls on the upper surface of the first stack plate 16 or the two second stack plates 17 in the parallel state, so as to avoid the material from falling from the discharge port 6 or the rectangular port 9. After the rectangular plate 11 and the pushing plate 10 move back to the original position, the first stack plate 16 also moves to the outside of the machine body 1. The material originally stacked on the upper surface of the first stack plate 16 is blocked by the inner wall of the machine body 1 and falls on the upper surface of the two second stack plates 17. Since the two threaded rods 20 are abutted against the two abutment plates 24 at this time, the two threaded rods 20 move into the threaded grooves 19, and the two mounting rods 18 relatively rotate with the two second stack plates 17. The two second stack plates 17 rotate to the inclined state, and the material on the upper surface of the second stack plate 17 falls through the gap between the two second stack plates 17 and then falls on the upper surface of the weighing plate 8.
[0030] In the initial state, before the material is weighed, the baffle 5 does not cover the bottom of the hollow column 2, and the pushing plate 10 is located in the rectangular port 9, and the rectangular plate 11 is located in the discharge port 6, at this time, the material is poured into the hollow column 2 from the feeding hopper 3, and falls onto the weighing plate 8, and is measured by the weighing sensor 7, when the material weight measured by the weighing sensor 7 reaches the set value, the output shaft of the driving motor 13 with the gear 14 is controlled to rotate in the positive direction, the two rack rods 15 meshed with the gear 14 are moved relatively with the baffle 5 and the pushing plate 10, the baffle 5 covers the bottom opening of the hollow column 2 during movement, so that the material cannot fall again, and the pushing plate 10 moves with the rectangular plate 11 during movement, and pushes the material accumulated on the upper surface of the weighing plate 8 out of the discharge port 6, so as to complete the discharging, then the weighing sensor 7 measures that there is no material on the weighing plate 8, controls the output shaft of the driving motor 13 with the gear 14 to rotate in the reverse direction, moves the baffle 5 and the pushing plate 10 to reset, the pushing plate 10 moves into the rectangular port 9 again, the rectangular plate 11 is located in the discharge port 6, and the baffle 5 does not cover the bottom of the hollow column 2, at this time, the material in the feeding hopper 3 falls from the bottom of the hollow column 2 to the upper surface of the weighing plate 8, and the above weighing steps are repeated, the feeding and discharging of the material can be automatically performed, and the weight of the material to be poured can be accurately controlled, manual weighing is not required, the labor burden of workers is reduced, the weighing error can be avoided, and the qualified rate of the final product is improved.
