The buffer containers 11 are provided with a feeding mechanism 12, a discharge on-off valve 13, and a docking interface 14 for docking the carrier container 2. The bracket 3 is provided with a first weighing module 31 for weighing the carrier container 2. The lifting mechanism 4 is provided with a second weighing module 42 for weighing the bracket 3. The feeding mechanism 12 is preferably a vacuum feeding mechanism that uses negative pressure to suck the material into the buffer container 11. Of course, in other embodiments, a mechanical lifting type feeding mechanism can also be used, which will not be described in detail. The discharge on-off valve 13 is preferably an electric rotary valve, which is convenient for automatic control and has a corresponding high speed. The storage platform 1 can be provided with a staircase 15 to facilitate workers to go up and down the storage platform 1 for installation, maintenance, repair, and other operations. At the same time, a guardrail 16 is provided on the storage platform 1 to ensure the safety of the workers. The carrier container 2 is preferably a square funnel-shaped structure with a large opening at the upper part for easy docking with the docking interface 14 for feeding, and a small opening at the lower part for easy transfer to the granulation system 300 after the material is mixed evenly.

[0044] In operation, the feeding mechanism 12 feeds the corresponding material into the buffer container 11, the bracket 3 supports the carrier container 2, and the lifting mechanism 4 and the translation mechanism 5 drive the bracket 3 and the carrier container 2 supported thereby to move, thereby sequentially docking with the docking interfaces 14 of the respective buffer containers 11.

After the weighing is completed, the two sets of weighing modules obtain the weight data of the material, which is compared to obtain the precise set material amount, thereby being beneficial to ensuring the accuracy of the material weighing, having a simple and reliable structure, low cost, convenient docking of the carrier container 2, and wide application occasions.

[0045] Further, in the embodiment, the bracket 3 comprises a bracket body 34 and a pair of bracket arms 32 arranged on the bracket body 34, the bracket arms 32 are horizontally arranged, and the first weighing modules 31 are installed at two ends of the bracket arms 32 and the installation surfaces are located at the same horizontal plane. The main factor of the accuracy of the first weighing modules 31 is the horizontal degree of the bracket arms 32, and meanwhile, it is ensured that no other components interfere with the bracket 3. The horizontal arrangement of the bracket arms 32 and the installation surfaces of the first weighing modules 31 located at the same horizontal plane are beneficial to ensure the accuracy of the first weighing modules 31. Preferably, the bracket body 34 is arranged along the vertical direction, so as to form the bracket 3 with the bracket arms 32 in an L-shaped structure.

When the load container 2 needs to be lifted, the lifting driving component 45 drives the lead screw 44 to rotate, the nut seat on the lead screw 44 is lifted along the lead screw 44, and the nut seat drives the weighing frame 43 and the bracket 43 to lift through the second weighing module 42. Since the weighing frame 43 is provided with a through hole for the lead screw 44 to pass through, the weighing frame 43 can be fully in contact with the second weighing module 42, which is beneficial to ensure that the whole weight of the bracket 3 acts on the second weighing module 42 through the weighing frame 43, and the structure is simple and reliable.

[0048] As a preferred embodiment, the lifting guiding assembly 6 is arranged between the bracket 3 and the lifting mechanism 4, which can be a slide rail and slide block assembly, a slide rail and roller assembly, or a guide column and guide sleeve assembly, and the like, which will not be described herein.

When the material loading container 2 needs to be moved, the translation driving assembly 53 drives the translation bracket 52 to move along the translation slide rail 51, and the lifting mechanism 4, the carrier 3, and the material loading container 2 move as a whole with the translation bracket 52. The translation slide rail 51 can provide a guiding effect for the translation bracket 52, ensure smooth movement, and avoid deviation, and the structure is simple and effective.

[0050] Further, in the embodiment, the translation driving assembly 53 comprises a translation driving part 531 (for example, a speed reducer motor), a driving gear 533, and a rack 532 matched with the driving gear 533, the translation driving part 531 is arranged on the translation bracket 52, the driving gear 533 is connected with the translation driving part 531, and the translation slide rail 51 is arranged on both sides of the rack 532. When the material loading container 2 needs to be moved, the translation driving part 531 drives the driving gear 533 to rotate, the driving gear 533 moves along the rack 532 while rotating, and the translation bracket 52 moves along the translation slide rail 51 accordingly. The translation slide rail 51 is arranged on both sides of the rack 532, has good symmetry, is beneficial to force balance of the translation bracket 52, and has good dynamic stability.

[0051] As a preferred embodiment, the material loading container 2 is arranged on a material loading trolley 21, manual transfer of the material loading container 2 is facilitated, the trolley 21 is provided with a carrier connecting part 22, and the carrier 3 is provided with a trolley limiting part 35.

[0055] S2, the second cache container 11 ingredients: translation mechanism 5 drive load container 2 to move to the second cache container 11 below, lifting mechanism 4 load container 2 to rise and the second cache container 11 docking interface 14 docking, the second cache container 11 discharge switch valve 13 open to add material to the load container 2, until the first weighing module 31 and the second weighing module 42 obtained weight data respectively reach the corresponding value, the discharge switch valve 13 is closed, lifting mechanism 4 drive load container 2 down;

[0058] Preferably, initially, the discharge switch valve 13 is fully open, the corresponding batching speed is V1, so the value of V1 is maximum, which is beneficial to ensure the batching efficiency; as the material in the load container 2 gradually approaches the first target value (for example, 25 kg), the discharge switch valve 13 is partially closed, the corresponding batching speed is V2, V2 is a relatively large value and V2 < V1; as the material in the load container 2 gradually approaches the second target value (for example, 28 kg), the discharge switch valve 13 is further closed, or nearly completely closed, the corresponding batching speed is V3, so V3 is very small, V3 < V2, until the material in the load container 2 approaches the final target value (for example, 30 kg), the discharge switch valve 13 can be completely closed in a very short time, and the corresponding cache container 11 completes the batching, which is beneficial to accurately control the batching amount of different materials and avoid causing different materials to be scrapped due to batching error.
