[0002] In the fine chemical industry, achieving high-precision batching for small additives or small-batch production is a key step in achieving flexible, automated, and intelligent production. However, traditional batching equipment has the following problems: 1. Poor batching accuracy, typically 0.1% or even 1% of system accuracy, which cannot meet the required accuracy of 1g or even 0.2g for a batch of approximately 10kg. 2. Inability to batch ingredients simultaneously, with most using the gain-in-weight method, requiring queues for batching, long batching times, and low production efficiency. 3. Narrow scope of application, demanding high material requirements, making it difficult to achieve high viscosity, highly corrosive materials, or meet requirements for no cross-contamination. 4. Batching with manual floor scales or electronic scales cannot be automated, making data difficult to save.

[0027] Reference Figure 1-Figure 3 , the embodiment of the utility model provides a high-precision loss-in-weight batching station.

[0028] Specifically, the high-precision loss-in-weight batching station includes a support platform 5 and a weighing system. The weighing system is arranged at the top of the support platform 5. The weighing system includes multiple weighing units 2. Each weighing unit 2 is connected to a storage tank 3. A feed valve 1 is provided on the top of the storage tank 3, and a discharge valve 4 is provided at the bottom of the storage tank 3. The feed valve 1 is connected to the feed pipe. When the feed valve 1 is opened, the material is allowed to enter the corresponding storage tank 3 to wait for batching. When the discharge valve 4 is opened, the material is allowed to flow out of the corresponding storage tank 3 for batching. The weighing unit 2 detects the weight of the connected storage tank 3 in real time. When batching, the weight reduction of the storage tank 3 is used as the weight of the outflowing material.

[0032] In some embodiments, the feed valve 1 is located at the top of the storage tank 3 near the outer side; the discharge valve 4 is located at the bottom of the storage tank 3 near the inner side.

[0033] In some embodiments, the bottom surface of the storage tank 3 is tilted so that the height of the bottom surface close to the outer side surface is higher than the height of the bottom surface close to the inner side surface, and the material in the storage tank 3 automatically converges to the inner side surface where the discharge valve 4 is located.

[0034] In some embodiments, the discharge valve 4 is pneumatically controlled. Under the action of the air source pressure, the opening and closing and the opening degree of the discharge valve 4 are controlled by adjusting the size of the air source signal. When mixing materials, a large opening can be used for rapid feeding in the first half, and a small opening can be used for fine feeding in the second half to meet the feeding accuracy requirements.

[0035] In a specific implementation, the discharge valve 4 adopts a pneumatic angle seat plunger valve.

[0036] In some embodiments, a PLC control unit is also included, which is connected to the feed valve 1, the weighing system and the discharge valve 4. The PLC control unit obtains the weighing data of each weighing unit 2 of the weighing system and controls the opening and closing and opening degree of the feed valve 1 and the discharge valve 4.

[0037] In some embodiments, a batching barrel 6 is further included. The batching barrel 6 is disposed below the discharge valve 4 to collect the material flowing out of the discharge valve 4 .

[0038] In some embodiments, a power track 7 is further included, and the support platform 5 allows the power track 7 to pass through. The batching barrel 6 is set on the power track 7 and is driven by the power track 7 to move to the bottom of the discharge valve 4, thereby realizing a fully automatic batching process.

[0039] In summary, the high-precision loss-in-weight batching station provided by the utility model is equipped with multiple storage tanks 3, and weighing units 2, feed valves 1 and discharge valves 4 are arranged corresponding to the storage tanks 3, so as to realize the separate batching of materials in each storage tank 3 at the same time; the opening and closing and opening degree of the discharge valve 4 are controllable, and during batching, the material can be quickly added with a large opening in the first half and finely added with a small opening in the second half, thereby meeting the feeding accuracy requirements.

[0040] Furthermore, the present invention realizes the coordinated control of the weighing unit 2 and the discharge valve 4 through the PLC control unit, and simultaneously realizes the storage of the weighing data of the weighing system.
