Description

Technical Field

[0001] The utility model relates to the technical field of stirring and dispersing paddles, in particular to a stirring and dispersing paddle for producing conductive silver paste. Background Art

[0002] In the production process of conductive silver paste, the physical dispersion process runs through the entire production process. Specifically, the production process involves the dissolution of different resins in solvents. The glue after the resin is dissolved is then fully stirred and dispersed with different types of silver powders with different functions, diluent solvents, functional additives, etc. to finally produce conductive pastes with different properties.

[0003] The most commonly used process in the above production process is the stirring and dispersing process. Different materials in the above process have different physical properties. Some raw materials are micron-level powders, some are solvent fluids, some raw materials and intermediate products are pastes with good thixotropy, and some are jellies. In the large-scale production process, it is necessary to fully and evenly disperse various raw materials with different physical properties. Good dispersing and stirring equipment is needed to complete it.

[0004] In the prior art, the paddle structure used for dispersion and stirring has the disadvantages of overflowing and flying materials, raising dust, low yield, high energy consumption, and uneven front-end dispersion. In view of this, we propose a stirring and dispersing paddle for the production of conductive silver paste. Utility Model Content

[0005] The main purpose of the utility model is to provide a stirring and dispersing paddle for producing conductive silver paste, which can solve the problems raised in the above technical background.

[0006] In order to achieve the above-mentioned object, the utility model provides a stirring and dispersing paddle for producing conductive silver paste, comprising a double-shaft stirring shaft, wherein the double-shaft stirring shaft comprises:

[0007] A double-axis left stirring shaft, a double-axis right stirring shaft is arranged on the side of the double-axis left stirring shaft, an upper left stirring paddle is fixedly connected to the upper surface of the double-axis left stirring shaft, a lower left stirring paddle is fixedly connected to the lower surface of the double-axis left stirring shaft, an upper right stirring paddle is fixedly connected to the upper surface of the double-axis right stirring shaft, a lower right stirring paddle is fixedly connected to the lower surface of the double-axis right stirring shaft, a stirring enhancement device is arranged inside the double-axis left stirring shaft, and the four dispersing paddles increase the pressure of the stirring material in addition to the stirring and dispersing functions, so that various materials can be more fully integrated.

[0008] Preferably, the upper left stirring paddle and the lower left stirring paddle are fixedly connected to the double-shaft left stirring shaft at a 135-degree incision angle. The 135-degree internal incision angle disperses and increases the shear force on the stirring material, which is more practical for stirring some superfrozen materials, shortens the stirring time, and reduces costs.

[0009] Preferably, the upper right stirring paddle and the lower right stirring paddle are fixedly connected to the double-shaft right stirring shaft at a 135-degree cut angle.

[0010] Preferably, the stirring enhancement device comprises a connector, the inner wall of the connector is slidably connected to the surface of the central axis, the surface of the central axis is provided with an inclined groove, and the inner wall of the inclined groove is slidably connected to the inner wall of the connector.

[0011] Preferably, the bottom surface of the central axis is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to one end of the connecting sleeve, and the other end of the connecting sleeve is rotatably connected to the inner wall of the left dual-axis stirring shaft.

[0012] Preferably, the surface of the central axis is hinged to one end of the connecting rod, the other end of the connecting rod is clamped to the surface of the push block, the bottom surface of the push block is fixedly connected to the upper surface of the extension page, the inner wall of the extension page is rotatably connected to the surface of the swing plate, the inner wall of the extension page is slidably connected to the surface of the guide rod, the two ends of the guide rod are fixedly connected to the inner wall of the upper left stirring paddle, the surface of the extension page is fixedly connected to one end of the push spring, and the other end of the push spring is fixedly connected to the inner wall of the upper left stirring paddle.

[0013] The utility model provides a stirring and dispersing paddle for producing conductive silver paste, which has the following beneficial effects:

[0014] (1) The stirring and dispersing paddle used in the production of the conductive silver paste is provided with four dispersing paddles on a double axis. The dispersing paddles carry the stirred material downward and inward during the rotation process, effectively avoiding the overflow of the material during the dispersion process, solving the problem of flying materials during the dispersion and stirring process, and avoiding the waste caused by the overflow and the imbalance of the original formula material ratio. At the same time, the overflow of dust during the mixing and dispersing process of the silver powder is reduced, the respiratory health of the operators is guaranteed, the work efficiency of the material dispersion is effectively improved, the energy cost is reduced, and the dispersion effect of the material is improved. In addition, the device has a simple structure and is easy to clean and operate.

[0015] (2) The stirring and dispersing paddle used in the production of the conductive silver paste is arranged through a central axis. When the motor drives the central axis to rotate through a connector, when the connector rotates, the connector pushes the central axis downward through an inclined groove, so that the central axis pushes the connecting rod to move, so that the connecting rod pushes the extension leaf to extend out of the upper left stirring paddle, so that when the extension leaf rotates, the swing plate stirs the uneven conductive silver paste, thereby achieving a better stirring effect.
