TECHNICAL FIELD
[0001] The present application relates to the technical field of adhesive mixing devices, more particularly to a mixing device for large-torque wet friction plate adhesive production. BACKGROUND
[0002] Large-torque wet friction plates are a type of friction device designed specifically for high-torque transmission needs, commonly found in mechanical systems that need to withstand large power loads. Large-torque wet friction plates are suitable for heavy machinery or high-power equipment, and the friction plate works in an oil environment, using lubricating oil for cooling and lubrication to reduce wear and improve durability.
[0003] When producing large-torque wet friction plates, adhesive is needed for bonding. Adhesive is a key material that firmly fixes friction materials to steel plate substrates, and its performance directly affects the durability, shear resistance, and high-temperature stability of the friction plate.
[0004] However, the existing adhesive mixing technology has the following problems. First, there are air bubbles in the adhesive mixing process, which greatly reduces the bonding effect of the adhesive. Second, traditional mixing devices use a single stirring mode, which can easily form dead corners during mixing, leading to uneven distribution of ingredients, especially for high-viscosity adhesives, which can easily cause local aggregation or stratification. Therefore, the present application provides a mixing device for large-torque wet friction plate adhesive production. SUMMARY

In the three shearing processes, the material is gathered forward, dispersed backward and gathered forward again, which greatly enhances the dispersibility of the material, reduces agglomeration and ensures uniform mixing of the adhesive components.
[0013] 2. The structure of the circular table threaded block and the gong barrel threaded block forms compression when rotating, simulates a high shear field, effectively breaks the internal molecular aggregation of the material and improves the mixing precision.

[0018] 7. The present application ensures controlled material advancement throughout the process through the conical transition of the circular cone barrel and the storage barrel and the continuous connection design of the thread blocks, thus avoiding the dead angle or residue problems commonly seen in traditional mixers and reducing raw material waste.
