Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry-process battery production, and in particular to a dry-process battery fiberization treatment device. Background Technology
[0002] Currently, dry electrode fabrication is a novel electrode preparation technology that does not use liquid solvents, but directly mixes solid powders of active materials, conductive agents, and binders together. The process involves first mixing the active materials, conductive agents, and binders; during mixing, the powder is drawn into fibers; then, the fibrous material is pressed into thin sheets and adhered to a foil.
[0003] CN220940135U discloses a dry electrode fiberization device, which, through the cooperation of a stirring mesh plate and stirring blades, can first disperse the binder evenly in the mixture, and then use shear force to shear the binder, causing the binder to become fiberized, which can greatly improve the viscosity of the entire mixture, thereby improving the feasibility and reliability of dry electrode materials.
[0004] However, in this patent, the main shear force is provided to the mixture through the stirring mesh and stirring blades, thereby causing the binder to become fibrous. However, during the fibrosis process, the shear force on the mixture directly affects the effectiveness of the chaotic fibrosis. Insufficient shear will lead to incomplete PTFE fibrosis, forming local agglomeration and increasing electrode impedance. However, excessive shear will cause the active material particles to break down and trigger side reactions to intensify. Therefore, how to effectively control the shear force applied to the mixture by the processing equipment is a very important indicator in the fibrosis of the mixture. Utility Model Content

[0024] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example 1
[0026] Reference Figures 1 to 6 This embodiment provides: a dry battery fiberization processing device, including a mixing tank 100, which is a hollow cylindrical shape. The top and bottom of the outer wall of the mixing tank 100 are respectively provided with a feed inlet 101 and a discharge outlet 102; and a stirring mechanism 200, which includes a mixing panel 201, a stirring roller 202 and a movable panel 203. The mixing panel 201 is rotatably connected inside the mixing tank 100. The mixing panel 201 has an inner groove 201b inside. The movable panel 203 is slidably connected inside the inner groove 201b of the mixing panel 201. The movable panel 203 has a second shaft groove 203a inside. The stirring roller 202 is rotatably connected inside the second shaft groove 203a of the movable panel 203.
[0027] A first servo motor 201a is fixedly connected to the outer wall of the mixing tank 100. The output end of the first servo motor 201a is fixedly connected to the mixing panel 201. A second servo motor 202a is fixedly connected to the bottom of the outer wall of the mixing tank 100. The output end of the second servo motor 202a is fixedly connected to the stirring roller 202. The stirring roller 202 and the mixing panel 201 are coaxial. During the fiberization process, the first servo motor 201a and the second servo motor 202a drive the mixing panel 201 and the stirring roller 202 to rotate in different directions on the same axis, respectively.
[0028] The outer wall of the mixing panel 201 is provided with several sets of first clearance grooves 201d, and the outer wall of the stirring roller 202 is fixedly connected with several sets of stirring blades 202b. The stirring blades 202b rotate inside the first clearance grooves 201d. The mixing panel 201 stirs the mixture inside the mixing tank 100. When the mixture passes through the first clearance grooves 201d, the stirring blades 202b cause the mixture to be squeezed out from the gaps in the first clearance grooves 201d, thereby achieving the fiberization of the mixture.
[0029] The outer wall of the mixing panel 201 is provided with several sets of first mixing holes 201e, and the outer wall of the movable panel 203 is provided with several sets of second clearance grooves 203b and second mixing holes 203c. The positions and numbers of the second clearance grooves 203b and second mixing holes 203c correspond to the positions of the first clearance grooves 201d and the first mixing holes 201e of the mixing panel 201.
[0030] The bottom of the movable panel 203 is provided with a threaded post, which is slidably connected inside the first shaft groove 201c of the mixing panel 201. A threaded pin 203d is threadedly connected to the outer wall of the threaded post. A pin groove 201f is opened on the outer wall of the mixing panel 201, and the threaded pin 203d is rotatably connected inside the pin groove 201f. When the threaded pin 203d is rotated, it is limited by the pin groove 201f of the mixing panel 201. Since the threaded pin 203d is threadedly connected to the threaded post of the movable panel 203, the movable panel 203 will slide up and down inside the inner groove 201b of the mixing panel 201. By sliding the movable panel 203 up and down, the size of the overlapping part of the first clearance groove 201d and the second clearance groove 203b is changed, thereby reducing the gap between the clearance groove and the stirring blade 202b. By changing the gap, the overall shear force of the device is changed, thereby controlling the overall fiberization effect of the mixing.
[0031] Furthermore, since the movable panel 203 slides inside the inner groove 201b of the mixing panel 201, the overlapping part of the second mixing hole 203c and the first mixing hole 201e will be adjusted, thereby controlling the mixing efficiency.
[0032] The first servo motor 201a and the second servo motor 202a are both common existing technologies in real life, so their structure, principle and power supply will not be described in detail here.
[0033] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values (e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.

In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and not only structural equivalents but also equivalent structures. Without departing from the scope of this invention, other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments. Therefore, this invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.
[0034] Furthermore, in order to provide a concise description of exemplary embodiments, not all features of actual embodiments (i.e., those features that are not relevant to the best mode of carrying out the present invention as currently considered, or those features that are not relevant to the implementation of the present invention) may be omitted.
