Description

Technical Field

[0001] The invention belongs to the technical field of conductive coating preparation, and in particular relates to a conductive coating raw material preparation device. Background Art

[0002] The raw materials of conductive coating are mainly composed of base resin, conductive filler, solvent and additives. The base resin provides the skeleton of the coating, the conductive filler gives the coating conductive properties, and the solvent and additives are used to improve the processing performance and stability of the coating. When selecting raw materials, it is necessary to match and adjust them according to the specific application scenarios and requirements.

[0003] A conductive coating slurry circulation transfer tank with Chinese patent publication number CN 221164253 U includes a motor, a shell and a screw rod. The motor output end is connected to the screw rod, and the motor is installed on the top of the shell. The screw rod penetrates the shell and extends into the shell. The motor is used to drive the screw rod to rotate. A discharge port is provided at the bottom of the inner wall of the shell, and a valve is installed at the outlet of the discharge port. The utility model is provided with a motor, a screw rod and a feeding barrel, etc. After the transportation is completed, the motor is connected to the power supply, and the motor is used to drive the screw rod to rotate. The material moves upward under the action of the screw rod until it enters the feeding barrel, so that the material overflows outward through the opening at the top of the feeding barrel, causing the material originally at the bottom to move to the top to complete the mixing, thereby solving the problem that the current transfer tank cannot autonomously mix materials of different batches, resulting in the material being unable to be used directly.

[0004] Through the clever coordination of the mechanism, different batches of materials can be easily mixed during the processing. However, there are some problems with the above design during use. The above design is not convenient for screening the pre-added powdered materials. Summary of the invention
