At the same time, the anti-agglomeration and anti-contamination effects are poor. Nanoparticles are prone to agglomeration due to electrostatic adsorption and humidity. Furthermore, the pipeline residue and cross-contamination rate are high when multiple materials are combined. Utility Model Content

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a precision small-batch batching system for multiple types of materials, including several independent material conveying channels 1, a confluence cavity 2, a weighing module 3, and a control module 4. Each material conveying channel 1 is provided with a coarse flow velocity control device 11, a fine flow velocity control device 12, and a micro flow velocity control device 13 in sequence along the material flow direction. The top of the confluence cavity 2 is provided with several material inlets 21, and the material inlets 21 correspond to the outlets of the micro flow velocity control devices 13 of different material conveying channels 1. The weighing module 3 is located at the bottom of the confluence cavity 2 and is used to monitor the total weight of the material in the confluence cavity 2 in real time. The control module 4 is electrically connected to the coarse flow velocity control device 11, the fine flow velocity control device 12, the micro flow velocity control device 13, and the weighing module 3.

[0029] This embodiment of the invention configures several independent material conveying channels 1, each channel connected in series with a three-level control device: a coarse-segment flow rate control device 11, a fine-segment flow rate control device 12, and a micro-segment flow rate control device 13. The outlet of each channel is connected to the corresponding inlet of a manifold 2 via a dedicated pipe. A high-precision weighing module 3 is integrated at the bottom of the manifold 2, which collects the total weight of the material in real time and transmits it to the control module 4. The control module 4, based on the logic of the coarse-segment flow rate control device 11 conveying 70%-90% of the target amount, the fine-segment flow rate control device 12 conveying 5%-15%, and the micro-segment flow rate control device 13 supplementing the remaining amount, controls the start and stop sequence of the feeders in each channel via electrical signals, achieving precise mixing of multiple material varieties according to a preset ratio. This achieves independent and precise control of materials with different characteristics, and through real-time weighing feedback and multi-level coordinated adjustment, significantly reduces the weight error of multiple material mixing, meeting the flexible production needs of precision small-material multi-variety manufacturing.

[0030] In one feasible implementation scheme, such as Figure 1 As shown, the inner wall of the material conveying channel 1 is provided with an anti-stick coating 14, which is a superhydrophobic nano-coating. By covering the inner wall of the material conveying channel 1 with the anti-stick coating 14, the coating is made of a composite material with low surface energy and is bonded to the pipe substrate using a special process. After surface treatment, a smooth interface is formed, reducing the adhesion between the material and the inner wall. This effectively reduces the amount of material residue in the pipe, avoids cross-contamination during the switching of multiple material types, reduces cleaning frequency, and improves the continuous operation efficiency of the system.

[0031] In one feasible implementation scheme, such as Figure 1As shown, the coarse section flow rate control device 11 includes a coarse section drive mechanism 111 and a coarse section adjustment component 112. The coarse section drive mechanism 111 is a screw feeder, and the coarse section adjustment component 112 is used to control the material flow rate to reach 70%-90% of the target weight. The fine section flow rate control device 12 includes a fine section drive mechanism 121 and a fine section adjustment component 122. The fine section drive mechanism 121 is an electromagnetic vibrating feeder, and the fine section adjustment component 122 is used to control the material flow rate to reach 5%-15% of the target weight. The micro section flow rate control device 13 includes a micro section drive mechanism 131 and a micro section adjustment component 132. The micro section drive mechanism 131 is a pulse feeder, and the micro section adjustment component 132 is used to control the material flow rate to make up for the remaining weight. By incorporating a spiral feeding structure in the coarse-section flow rate control device 11, the target quantity is rapidly conveyed by adjusting the drive speed. The fine-section flow rate control device 12 employs an electromagnetic vibration feeding structure, adjusting vibration parameters to achieve medium-speed replenishment. The micro-section flow rate control device 13 features a pulse feeding structure, precisely replenishing remaining material through micro-feeding. These three stages achieve seamless switching and coordinated operation via the control module 4. Through this three-stage progressive control—from efficient approximation to error reduction and then to precise correction—the accuracy of single-material batching is significantly improved, solving the problem of precise adjustment of small quantities of material and reducing the weight deviation of traditional single-stage control.

[0032] In one feasible implementation scheme, such as Figure 1 and Figure 2 As shown, the material inlets 21 of the manifold 2 are uniformly distributed circumferentially. By uniformly distributing the material inlets 21 circumferentially at the top of the manifold 2, with adjacent inlets arranged symmetrically at an angle, and the inlet pipes inclined at an angle to the inner wall of the manifold 2, the material enters the manifold 2 in a non-vertical direction. The uniformly distributed inlet layout and inclined feeding design promote the formation of circulating mixing of multiple materials in the initial stage of confluence, reduce material stratification, and improve the uniformity of confluence.

[0033] In one feasible implementation scheme, such as Figure 2 As shown, the inner wall of the confluence cavity 2 is provided with a vortex rib structure 22, which extends spirally along the axial direction of the confluence cavity 2. By setting the vortex rib structure 22 extending spirally along the axial direction on the inner wall of the confluence cavity 2, the ribs are integrally formed with the cavity wall, and the surface is smoothed to form a continuous flow guiding path. When the material flows through the vortex rib, turbulent disturbance is generated, which enhances the collision and diffusion effect between particles, and forms three-dimensional mixing in combination with the circulation motion, reducing agglomerate residue and improving the uniformity of multi-material mixing.

[0034] In one feasible implementation scheme, such as Figure 2As shown, a mixing component 23 is provided inside the manifold 2. The mixing component 23 includes a rotating disk 231 and a driving component 232. The rotating disk 231 is installed at the bottom of the manifold 2, and the driving component 232 is pulsatorically connected to the rotating disk 231. By installing the mixing component 23 at the bottom of the manifold 2, including the disk structure and the driving component, the driving component drives the disk to rotate. The surface of the disk is provided with a flow guiding structure to promote the diffusion and mixing of materials in the cavity. The centrifugal force and flow guiding effect generated by the rotation accelerate the diffusion of materials towards the cavity wall and form a uniform suspension state, further improving the mixing effect of multiple materials and reducing local concentration deviations.

[0035] In one feasible implementation scheme, such as Figure 2 As shown, an environmental monitoring component 24 is installed inside the manifold 2. This component includes a temperature and humidity sensor 241, an air pressure sensor 242, and a dust concentration sensor 243. By integrating the environmental monitoring component 24, which includes temperature, humidity, air pressure, and dust concentration monitoring elements, into the manifold 2, real-time environmental parameters inside and around the manifold are collected and transmitted to the control module 4. This enables real-time sensing of environmental parameters, providing a basis for the system's environmental adaptability adjustment, reducing the impact of temperature, humidity, and air pressure fluctuations on material flowability, and improving the stability of the batching process.

[0036] In one feasible implementation scheme, such as Figure 1 and Figure 2 As shown, the weighing module 3 consists of several sets of shear beam load cells. By employing multiple sets of shear beam load cells to form the weighing module 3, the sensors are evenly distributed at the bottom of the manifold 2 and connected by circuitry to form a weighing unit, providing real-time feedback of material weight signals. Through coordinated monitoring by multiple sets of sensors, the stability and accuracy of weight detection are improved, single-point measurement errors are reduced, and a reliable feedback benchmark is provided for multi-stage flow rate control.

[0037] In one feasible implementation scheme, such as Figure 1 As shown, the control module 4 has a built-in material characteristic database and an intelligent algorithm module. The built-in material characteristic database stores the physical characteristic parameters of different materials; the integrated intelligent algorithm module dynamically adjusts the action thresholds and timing logic of each level of flow rate control device based on feedback data from the weighing module 3 and environmental parameters. This achieves self-adaptive optimization of system parameters, reduces manual debugging costs, improves the efficiency and accuracy of switching between multiple material types, and enhances the system's adaptability to changes in material characteristics.

[0038] In the specific implementation of the multi-variety material precision batching system provided in this embodiment of the utility model, before the system is started, the operator enters the variety of materials to be batched, the preset ratio, and the target total weight into the control module 4 according to production needs. The control module 4 calls the built-in material characteristic database, matches the physical characteristic parameters of each material, and, in conjunction with the intelligent algorithm module, initially sets the action threshold of each level of flow rate control device. The coarse-section flow rate control device 11 needs to complete 70%-90% of the target weight conveying, the fine-section flow rate control device 12 is responsible for 5%-15% of the medium-speed replenishment, and the micro-section flow rate control device 13 accurately replenishes the remaining weight. At the same time, the shear beam type weighing sensor group at the bottom of the manifold 2 completes zero-point calibration, the environmental monitoring component 24 starts preheating, collects initial environmental parameters in real time and transmits them to the control module 4, providing reference data for subsequent adjustments. Each independent material conveying channel 1 starts according to the instructions of the control module 4, realizing three-level progressive conveying for different material characteristics:

[0039] Rapid conveying of coarse section: The screw feeder of the coarse section flow rate control device 11 is started, and the control module 4 adjusts the screw drive speed according to the material characteristic database, so that the material passes through the material conveying channel 1 covered with superhydrophobic nano anti-stick coating 14 at a high flow rate, reducing material residue in the initial conveying and quickly completing the conveying task of 70%-90% of the target amount.

[0040] Medium-speed feeding in the fine section: When the weighing module 3 reports that the material in a certain channel is close to the target threshold of the coarse section, the control module 4 triggers a switching signal, the coarse section screw feeder stops, and the electromagnetic vibrating feeder of the fine section flow rate control device 12 starts. By adjusting parameters such as vibration frequency and amplitude, the material is continuously conveyed at a medium speed to complete 5%-15% of the target amount of feeding. At this time, the anti-stick coating 14 further reduces the risk of material adhesion at the channel turning point.

[0041] Precise replenishment in micro-segments: When the target total amount is approached, the precision segment electromagnetic vibratory feeder stops, and the pulse feeder of the micro-segment flow rate control device 13 starts. Based on the real-time feedback of the total weight deviation of the manifold 2 from the weighing sensor, the control module 4 replenishes the remaining trace amount of material step by step through precise control of the pulse frequency and the amount of feed per cycle, ensuring that the conveying error of a single material is controlled within the minimum range.

[0042] After undergoing three-stage control, the materials in each channel enter the manifold 2 through the material inlets 21, which are evenly distributed circumferentially at the top of the manifold 2. The inlet pipes are inclined at an angle to the cavity wall, creating a circulating foundation for the initial entry of the materials. During the descent, the materials flow through the spirally extending vortex rib structure 22 on the inner wall, where the ribs guide the flow and generate turbulent disturbances, enhancing particle collisions and diffusion. Simultaneously, the mixing component 23 at the bottom of the manifold 2 is activated, and the drive component 232 drives the rotating disk 231 to rotate. The guiding structure on the surface of the disk, combined with centrifugal force, propels the materials to diffuse towards the cavity wall and form a uniform suspension state, effectively avoiding material stratification and local concentration deviations. Throughout the material conveying and mixing process, the system enters a closed-loop control state. Multiple shear beam weighing sensors at the bottom of the manifold 2 collect the total weight of the material inside the chamber in real time, and the data is synchronously transmitted to the control module 4. The control module 4 compares the actual weight with the preset value and dynamically corrects the pulse parameters of the micro-segment flow rate control devices 13 in each channel to ensure that the total weight deviation meets the precision requirements. The environmental monitoring component 24 continuously monitors the temperature, humidity, air pressure, and dust concentration inside the chamber. If the parameter fluctuations exceed the threshold, the intelligent algorithm module automatically adjusts the action sequence of each feeder to ensure stable material flow. When the weighing module 3 reports that the total weight has reached the preset value, the control module 4 instructs all micro-segment flow rate control devices 13 to stop working, completing this batching. The mixing component 23 continues to run for a preset time to ensure that the material is fully mixed before being discharged from the manifold 2. If it is necessary to switch material types, because the superhydrophobic nano anti-stick coating 14 on the inner wall of the material conveying channel 1 reduces residue, the control module 4 automatically calls the characteristic parameters of the new material and repeats the above process to enter the next batching cycle. Through the synergy of three-level precision delivery, multi-dimensional mixing and enhancement, real-time monitoring and feedback, and intelligent algorithm control, the system achieves high-precision proportioning and efficient production of various small materials, meeting the dual requirements of precision and efficiency for flexible manufacturing.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
