[0002] In the field of quantitative dosing technology, the current quantitative dosing of admixtures can present problems such as inaccurate dosing, poor continuity, and instability in the dosing process. Some existing quantitative dosing devices can struggle to precisely control the volume of admixture dispensed each time, leading to errors in the dosage. Alternatively, during operation, limitations in structural design can lead to air path entanglement and breakage, impacting the device's normal operation and the accuracy of quantitative dosing. Furthermore, maintenance and adjustment can be difficult, making it difficult to adapt to the demands of varying dosage specifications. Summary of the Invention

DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] like Figures 1-4 As shown, the precise quantitative dosing device for admixtures described in the present invention includes an outer shell 1, and the top and bottom of the outer shell 1 are fixedly connected with a feed funnel 2 and a discharge funnel 3 respectively. A support frame 4 is fixed on one side of the outer shell 1, and a servo motor 5 is installed on the support frame 4. The output end of the servo motor 5 is movable through the support frame 4 to extend to the interior of the outer shell 1 and is fixed with a first side plate 6. The first side plate 6 is rotatably connected to the interior of the outer shell 1, and a traveling swivel 7 is installed on the side of the first side plate 6 away from the servo motor 5. A plurality of feeding slots 8 are opened on the outer wall of the traveling swivel 7, and an ejection column 9 is slidably inserted into the interior of each feeding slot 8. A second side plate 11 is installed on the other side of the traveling swivel 7, and an airbag 12 is arranged between the second side plate 11 and the first side plate 6. The airbag 12 is located inside the traveling swivel 7. A limiting block 10 is fixed to the end of the ejector column 9 close to the center of the accompanying swivel 7, and the end of the limiting block 10 away from the ejector column 9 contacts the airbag 12. The diameter of the limiting block 10 is larger than the inner diameter of the feeding slot 8. The setting of the limiting block 10 can prevent the ejector column 9 from sliding out of the feeding slot 8. The two ends of the airbag 12 contact the first side plate 6 and the second side plate 11 respectively, which can enable the airbag 12 to extend or contract radially when expanding and contracting, so that the airbag can always contact the limiting block 10. The end of the airbag 12 close to the second side plate 11 is connected to a connecting tube 13, which is fixed through the second side plate 11. The setting of the connecting tube 13 can make the airbag 12 more convenient when inflating and deflating. The connecting tube 13 passes through the outer tube wall of one end of the second side plate 11 and is rotatably sleeved with an external tube 14. The rotatably sleeved external tube 14 allows the airbag 12 to be fully inflated normally while rotating with the accompanying swivel 7, so that the device can adjust the delivery amount without stopping. The first side plate 6 and the second side plate 11 are both connected to the accompanying swivel 7 by bolts, making the first side plate 6 and the second side plate 11 more convenient to assemble and disassemble. The servo motor 5 is electrically connected to the external power supply through the PLC controller. The TB6600 type PLC controller can effectively control the speed and direction of the servo motor 5, which can effectively ensure that the device can be driven normally.

[0017] Specifically, power transmission: servo motor drives the accompanying swivel to move in a circular motion The servo motor 5 is fixed on the support frame 4 , and its output shaft passes through the first side plate 6 , driving the accompanying swivel 7 to rotate around the interior of the outer shell 1 .

[0018] A feeding slot 8 is provided on the outer wall of the accompanying swivel 7. The slot rotates with the swivel and passes through the feeding funnel 2 (loading area) and the discharging funnel 3 (unloading area) in sequence, thus realizing the cycle of "loading → transporting → unloading".

[0019] Quantitative control: air bag + ejector column locks the feeding volume The ejector column 9 is embedded in the feeding groove 8, and the diameter of the limit block 10 at one end is larger than the inner diameter of the groove to prevent the ejector column from sliding out; the other end is close to the center of the rotating ring.

[0020] The airbag 12 is sandwiched between the first side plate 6 and the second side plate 11 and has radial expansion and contraction capabilities: The airbag always contacts the limit block 10 and fixes the position of the ejector post in the through slot by elastic force, so that the "material filling space" in the through slot (through slot volume minus the volume occupied by the ejector post) is constant.

[0021] When the swivel rotates, the airbag expands / contracts synchronously with the change in the distance between the side plates, continuously maintaining resistance to the limit block, ensuring that the volume of each loading is consistent and achieving quantitative loading.

[0022] Air circuit protection: connecting tube + external tube to maintain airbag pressure One end of the connecting tube 13 is connected to the airbag 12, and the other end passes through the second side plate 11 and is rotatably connected to the external tube 14: The external tube is fixed to the outside of the device and connected to the air source. When the connecting tube rotates with the swivel, the external tube allows it to rotate 360° to ensure the continuity of airbag inflation / pressure maintenance, avoid air path entanglement or breakage, and maintain the stability of the airbag elastic force.

[0023] Structural assistance: disassembly and adjustment to optimize operational stability The first side plate 6 and the second side plate 11 are connected to the accompanying swivel 7 by bolts, which facilitates disassembly, maintenance and spacing adjustment (adapting to swivels or air bags of different specifications), ensuring long-term stable operation of the device.

[0024] The device achieves precise quantitative dosing of admixtures through a closed-loop process of "servo motor driven rotary circulation → air bag locking the ejector column position → constant volume loading → rotary operation and unloading": Quantitative: The elastic resistance of the airbag 12 keeps the ejector post 9 in a fixed position, and the effective charging volume of the feeding channel 8 is constant; Continuity: The swivel circulation motion and the air path design ensure the continuous operation of loading and unloading; Stability: The bolt connection and the limit structure lifting device have the flexibility of disassembly and assembly and the reliability of operation.

[0025] In use, the admixture to be dosed is added to the inside of the feed hopper 2, the inflation diameter of the air bag 12 is adjusted according to the amount of admixture to be added, after the inflation and deflation of the air bag 12 is completed, the dosing amount is related to the length of the ejection column 9 inserted into the inside of the feeding channel 8, when the length of the ejection column 9 inserted into the inside of the feeding channel 8 is longer, then the feeding channel 8 can accommodate less admixture, and vice versa, the amount of admixture that can be accommodated is increased, after the adjustment is completed, the servo motor 5 can be started, when the servo motor 5 is started, the first side plate 6, the traveling ring 7, the second side plate 11 and the air bag 12 can be synchronously rotated, in the process of rotating the traveling ring 7, the feeding channel 8 can be filled with admixture after being communicated with the feed hopper 2, and when the feeding channel 8 is communicated with the discharge hopper 3, the admixture in the inside of the feeding channel 8 will be discharged, the ejection column 9 set under the action of gravity can more efficiently and sufficiently push the additive out of the feeding channel 8, and can avoid the additive remaining in the inside of the feeding channel 8.
