[0002] In the production process of lithium battery adhesives, the conveying and transfer system is responsible for transporting the completed adhesive product from the reactor to the next processing step or storage area. The conveying and transfer system can automate the conveying task, and the closed conveying system can reduce material leakage and volatilization, thereby reducing environmental pollution and safety risks.
[0003] However, existing conveying and transfer systems have obvious defects and limitations in actual use. The material conveying capacity of these systems is limited by the viscosity of the material; excessively viscous materials may clog the conveying pipes, affecting production efficiency and creating safety hazards. Furthermore, adhesive materials may generate air bubbles, affecting quality.
[0004] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

The anti-stick coating 260 is provided on the surface of the fluid microchannel 240 and the guide vane 250. The fluid microchannel 240 has a corrugated structure.
[0021] The feeding device 300 includes: a screw pump 310, a feeding screw 320, a coupling 330, and a drive motor 340. One side of the screw pump 310 is connected to the hopper 100, and the other side of the screw pump 310 is connected to the inlet end of the first pipe 210.

[0022] The principle of this utility model is to set three pipes on the same straight line, with the pipe diameter increasing segment by segment. The first pipe 210, the second pipe 220 and the third pipe 230 are respectively provided with fluid microchannels 240. The fluid microchannels 240 are embedded in the inner wall of the pipe as an embedded structure to ensure the smooth passage of the adhesive. The width of the fluid microchannels 240 is set in the pipe in a gradually changing form inside the pipe so as to maintain good flow characteristics at different flow rates and reduce dead corners and stagnation areas.
[0023] In operation, the feeding device 300 extracts the adhesive from the silo 100 via a screw pump 310 and then conveys it into the conveying pipeline 200. The adhesive is gradually accelerated in the first pipeline 210, the second pipeline 220, and the third pipeline 230. The design of the fluid microchannel 240 and the guide vanes 250 reduces eddies and dead zones, ensuring smooth flow of the adhesive. The application of the anti-stick coating 260 reduces adhesive adhesion to the inner wall of the pipeline, lowering resistance and material loss. The sealing flange 270 ensures the system's airtightness and prevents material leakage. The temperature control device 400, connected to the conveying pipeline 200, controls the temperature of the adhesive, ensuring it remains within an appropriate temperature range during transport and preventing viscosity changes due to temperature variations. The control system 500 is an existing PLC control system; since PLC control systems are existing technology, they will not be described in detail here. The control system centrally manages the silo 100, the conveying pipeline 200, the feeding device 300, and the temperature control device 400, ensuring coordinated system operation. The control system 500 can achieve automated control and monitoring, ensuring the safe and stable operation of the system.
[0024] This invention reduces the flow resistance of lithium battery adhesive materials by adding segmented conveying pipes and gradually increasing the internal diameter of the pipes in each segment. This reduces the risk of blockage of highly viscous materials during the conveying process. In addition, the addition of fluid microchannels increases the internal surface area of the pipes, thereby improving the fluidity and uniformity of the adhesive.
[0025] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
