Description

TECHNICAL FIELD

[0001] The application relates to a self-adaptive stirring device and method for a dispersion barrel for graphene coating production. BACKGROUND

[0002] Graphene coating has a wide application prospect in high-end industrial fields due to its excellent electrical conductivity, mechanical strength and corrosion resistance. However, strong van der Waals forces exist between graphene nanosheet layers, and the graphene nanosheet layers are prone to agglomeration in the production process, which leads to uneven dispersion of the graphene in the matrix and significantly reduces the final performance of the coating (for example, the loss of electrical conductivity can be more than 70%).

[0003] At present, the dispersion process mainly relies on high-speed stirring equipment, but most of the stirring equipment on the market is designed for specific barrel diameters. When different specifications of dispersion barrels are replaced, the mechanical structure needs to be adjusted or the stirring head needs to be replaced, which cannot dynamically adapt to changes in barrel diameter (for example, Φ500mm to Φ800mm barrel switching needs to be stopped), which seriously affects the efficiency of the production line. In view of this, the application provides a self-adaptive stirring device and method for a dispersion barrel for graphene coating production to solve the above problems. SUMMARY

[0008] As the improvement of the above technical scheme, the supporting sleeve is provided with a lifting plate; The stirring assembly comprises a stirring fixed plate, the stirring fixed plate is connected with the lifting plate through bolts, the stirring fixed plate is provided with a stirring servo motor, a stirring rod is drivingly connected to the stirring servo motor, and the stirring rod is provided with stirring blades.

[0009] As the improvement of the above technical scheme, two groups of supporting fixed plates are symmetrically arranged on the supporting column, a guide rod is arranged between the two groups of supporting fixed plates, and the supporting sleeve is slidingly arranged on the outer wall of the guide rod.

[0010] As the improvement of the above technical scheme, a screw rod is arranged between the two groups of supporting fixed plates, a threaded sleeve is threadedly arranged on the outer wall of the screw rod, and a connecting reinforcing plate is arranged between the threaded sleeve and the supporting sleeve.

[0011] As the improvement of the above technical scheme, two groups of side plates are arranged between the two groups of supporting fixed plates, the two groups of side plates are symmetrically arranged, and the side plates are connected with the supporting fixed plates through bolts; A supporting servo motor is arranged on the side plate, a supporting speed reducer is arranged on the supporting servo motor, and an output shaft of the supporting speed reducer is connected with the screw rod.

[0012] As the improvement of the above technical scheme, a back-shaped frame is arranged on the base, two groups of first supporting rods are arranged on the back-shaped frame, second supporting rods are arranged on the first supporting rods, and the second supporting rods are connected with the supporting plates; A plurality of fixing holes are formed in the back-shaped frame.

[0013] A use method of a self-adaptive stirring device of a dispersion barrel for graphene coating production, comprising the following steps: S1, positioning the dispersion barrel: Place the dispersion barrel carrying materials at the designated work station on the side of the base; S2, dynamically adjusting the stirring area: Control the reciprocating rotation of the rotating disc through the driving assembly to drive the supporting column to move around the axis of the rotating disc, so that the horizontal projection position of the stirring assembly is self-adaptively matched with the diameter range of the dispersion barrel; S3, precisely adjusting the stirring depth: Start the supporting servo motor to drive the screw rod to rotate, and drive the supporting sleeve to vertically ascend and descend along the guide rod through the threaded sleeve, so that the stirring blades are immersed in the materials to a preset depth; S4, performing self-adaptive stirring: Synchronously start the stirring servo motor to drive the stirring rod to rotate, and maintain the reciprocating rotation motion of step S during the stirring process, so that the stirring blades form a dynamically changing shearing path in the dispersion barrel, and the stirring blades are kept in contact with the barrel wall throughout the process.

[0014] As an improvement of the above technical solution, the use method further comprises a multi-dispersion barrel cooperative processing step: S5, at least two dispersion barrels are arranged circumferentially on the base; S6, after the first dispersion barrel is completed, the rotating disc is driven to rotate by the driving assembly to rotate by a set angle, so that the support column is accurately aligned with the next target dispersion barrel; S7, repeat steps S3 and S4 to perform stirring work on the target dispersion barrel; S8, repeat steps S6 and S7 until all dispersion barrels are processed.

Of course, when multiple dispersion barrels are arranged circumferentially on the base, the rotation of the rotating disc can accurately align the support column with the dispersion barrels in different directions. After the stirring assembly enters the target barrel through lifting, the device can sequentially perform stirring work on multiple dispersion barrels, significantly improving the utilization rate and production efficiency of a single device, and reducing repeated investment in equipment. Through the reciprocating rotation of the support column, the working path of the stirring assembly can be adaptively adjusted according to the actual diameter of the dispersion barrel. Regardless of the size of the dispersion barrel, the stirring assembly can effectively cover the area closer to the barrel wall while maintaining a safe distance (not in contact with the barrel wall), thereby enhancing the versatility and adaptability of the device to different specifications of the dispersion barrel. In view of the characteristics of the material (especially containing nano graphene particles) in the production of graphene coating, which is prone to agglomeration and difficult to disperse, the continuous dynamic displacement of the stirring assembly in the barrel not only enhances the mixing efficiency of the macro fluid, but also more effectively breaks the particle agglomerates through the constantly changing shear area, promotes the uniform dispersion and stability of nano materials such as graphene in the matrix, and thereby significantly improves the performance and quality consistency of the final coating product.
