[0026] Among them, the weighing structure is achieved by placing the packaging bag in the placement rack 8, the opening of the packaging bag can be mounted on the top of the placement rack 8, and a weight 17 is arranged on the connecting plate 9, so that the connecting plate 9 falls to the lowest end due to gravity and the valve 10 is opened, and the chloroacetic acid particles fall into the packaging bag. When the weight reaches a weight greater than the weight 17, the placement rack 8 is pressed down by gravity, driving the connecting plate 9 to move upward through the cable 12, and the valve 10 is pushed closed.

[0027] Furthermore, the top end of the fixing column 14 is fixedly connected to the bottom end of the fixing platform 5 , the stabilizing ring 15 is fixedly connected to the outer wall of the placement rack 8 , and the fixing column 14 and the stabilizing ring 15 are slidably connected.

[0032] When the first rack 18 rises, the second rack 23 drives the valve 10 to move into the feed hopper 6 to close the feed hopper 6. When the first rack 18 descends, the second rack 23 drives the valve to move outward to open the feed hopper 6 to let the chloroacetic acid particles fall.

[0033] Working principle: When using the instrument, first start the conveyor belt 4, then put the packaging bag in the placement rack 8, the opening of the packaging bag can be set at the top of the placement rack 8, at this time, a weight 17 of appropriate weight is placed on the connecting plate 9, the connecting plate 9 is pressed to the lowest end, the connecting plate 9 drives the first rack 18 to descend, the first rack 18 drives the second gear 22 to rotate through the first gear 21, the second gear 22 drives the second rack 23 to move outward, and drives the valve 10 to open, at this time, put the chloroacetic acid particles into the feed hopper 6, and then you can start filling the bag, and then when the weight of the packaging bag is greater than the weight of the weight 17, put The rack 8 moves downward under the force of gravity, driving the cable 12 to move, and then drives the connecting plate 9 to move upward through the first guide wheel 11 and the second guide wheel 16. The connecting plate 9 therefore drives the first rack 18 to move upward, and the first rack 18 drives the second rack 23 to move into the feed hopper 6, and pushes the valve 10 to close. After no more chloroacetic acid particles fall, the filled packaging bag is promptly removed and a new packaging bag is connected, and then the above process is repeated, so that the valve 10 can be automatically closed after the chloroacetic acid particles are packaged and weighed, and under the influence of the weight 17, it can be ensured that the weight in the packaging bag is relatively balanced, and it is also relatively simple to use.
