[0039] The edge of the bottom opening of the discharging hopper 4 is also outwardly formed with a connecting plate 41.

[0040] Working principle: the modified plastic particles are poured into the inside of the feeding cylinder 1 through the top opening of the feeding cylinder 1, then fall into the top of the cylinder cover 32 in the material storage device 3 through the bottom opening of the feeding cylinder 1, and then spread around along the slope of the top of the cylinder cover 32, a part of the modified plastic particles enter the first material cabin 34 through the top opening of the first material cabin 34 in the corresponding material storage unit after sliding through each distribution plate 21 until the first material cabin 34 is filled, and the remaining modified plastic particles directly fall into the discharging hopper 4 through each discharging channel 22.

[0041] A weighing tool is arranged below the discharging hopper 4, and a receiving container is placed on the weighing tool, the top opening of the receiving container is arranged directly below the bottom opening of the discharging hopper 4, and the modified plastic particles in the discharging hopper 4 fall into the receiving container through the bottom opening of the discharging hopper 4 until the weight of the modified plastic particles in the receiving container approaches the set value.

[0042] The pouring of the modified plastic particles is stopped, and then the control valve on the first hopper 34 in one of the storage units is opened to make the modified plastic particles in the first hopper 34 all fall into the second hopper 35 below it. Since the volume of the first hopper 34 is greater than that of the second hopper 35, the falling modified plastic particles will all fall into the discharge hopper 4 and then into the receiving container after the second hopper 35 is filled, and the weight of the modified plastic particles in the receiving container is slightly increased, but still less than the set value.

[0043] Then the control valve on the second hopper 35 is opened to make the modified plastic particles in the second hopper 35 all fall into the discharge hopper 4 and then into the receiving container, so as to further increase the weight of the modified plastic particles in the receiving container, and then the other storage units are operated in turn until the weight of the modified plastic particles in the receiving container accurately reaches the set value.

[0044] The opening principle of the control valve on the first hopper 34 is as follows: the other end of the L-shaped pull plate 310 in the first opening mechanism is pressed downward, and then the first baffle 36 is swung by the first connecting rod 311, so that the second baffle 37 is pushed in the opposite direction by the second connecting rod 312, and then the swinging side of the first baffle 36 and the swinging side of the second baffle 37 are gradually separated, so that the bottom opening of the first hopper 34 is opened to make the modified plastic particles fall.

[0045] The opening principle of the control valve on the second hopper 35 is as follows: the other end of the straight pull plate 314 in the second opening mechanism is pressed downward, and then the first baffle 36 is swung by the third connecting rod 315, so that the second baffle 37 is pushed in the opposite direction by the fourth connecting rod 316, and then the swinging side of the first baffle 36 and the swinging side of the second baffle 37 are gradually separated, so that the bottom opening of the second hopper 35 is opened to make the modified plastic particles fall.

[0046] In addition, the opening of the control valve can be automatically completed. When operating, the servo motor 318 in the electric module is started to make its rotating shaft rotate counterclockwise, and then the swing arm 313 swings towards the other end of the L-shaped pull plate 310 or the other end of the straight pull plate 314. When the pin shaft 313 contacts the other end of the L-shaped pull plate 310 or the other end of the straight pull plate 314, it will gradually press the other end of the L-shaped pull plate 310 or the other end of the straight pull plate 314 downward to finally realize the opening of the control valve. When the pin shaft 313 leaves the other end of the L-shaped pull plate 310 or the other end of the straight pull plate 314, the L-shaped pull plate 310 and the straight pull plate 314 will contact the elastic return function of themselves to reverse and reset, and finally make the swinging side of the first baffle 36 and the swinging side of the second baffle 37 press again to automatically close the control valve.

[0047] The utility model discloses can store the part modified plastics granule in each storage unit in the discharging process, and can according to the difference size of actual weight and set weight in turn put out the modified plastics granule in several storage units in batches, and then gradually and automatically increase the actual weight of modified plastics granule in small amount to gradually reduce the difference between the actual weight of modified plastics granule and set weight, until both reach the consistency, and then save the necessary of manual adjustment discharge weight after discharging, thereby simplify the packing step of modified plastics granule to reach the effect of time saving and labor saving, and then improve work efficiency.

[0048] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the utility model, rather than limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
