Description

Technical Field

[0001] The utility model relates to lithium battery material production equipment, in particular to a cylindrical compaction type cutter. Background Art

[0002] In the lithium battery cathode material industry, a cutting device is required after the material is loaded into the pot during the sintering process. To increase the contact area between the material and the furnace atmosphere, the material is typically cut into pieces after loading. This ensures that the interior of the material is exposed to the external atmosphere, inhibits lithium / nickel mixing during sintering, and improves the material's electrochemical performance.

[0003] At present, the gaps between different cut pieces of traditional cutters are small, and the bottom material has insufficient contact with the atmosphere; the shape stability of the material after cutting is poor, and the vibration during the subsequent track conveying into the furnace can easily cause the cut pieces to collapse and block the gaps; finally, the sintered material is compacted together, which is not conducive to subsequent crushing.

[0004] Traditional cutters do not have the ability to compact during the cutting process. When producing some lithium-rich products, the lithium in the material at the bottom of the sagger will boil at high temperatures and transfer to the top of the sagger, resulting in uneven reaction of the material at the bottom and affecting the electrical performance of the product. Utility Model Content

[0005] The purpose of the present invention is to overcome the above-mentioned background technical difficulties and provide a cylindrical compacting cutter with a circular hole shape after cutting, so as to improve the stability of the cut blocks.

[0006] To achieve the above purpose, the technical solution adopted is: a cylindrical compaction cutter, including a mounting plate, on which a plurality of cylindrical cutters are arranged perpendicular to the mounting plate, and the cylindrical cutters are evenly distributed in an array.

[0007] Furthermore, the cylindrical cutter is detachably connected to the mounting plate.

[0008] Furthermore, the mounting plate is provided with fixing holes.

[0009] Furthermore, the cylindrical cutters are arranged in a square array, with a total of 16.

[0010] Furthermore, the top of the cylindrical cutter is provided with a pointed portion.

[0011] Furthermore, the outer surface of the cylindrical cutter at the contact point with the mounting plate is in a truncated cone shape.

[0012] Furthermore, the cylindrical cutter is multi-segmented, and the outer surface of the connection between the multiple segments is in a truncated cone shape.

[0013] The advantages of this solution are as follows: This cylindrical compaction cutter utilizes a cylindrical cutter assembly, resulting in a circular hole-shaped block after cutting. This prevents the blocks from collapsing during transportation, significantly improving the stability of the cut blocks. The cylindrical cutter is detachably connected to the mounting plate, allowing the cutter assembly to be replaced at different heights to adjust the compaction state of the cut material.

[0019] The following is a clear and complete description of the technical solution of the present invention in conjunction with the specific embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1 A cylindrical compaction cutter includes a mounting plate 2, on which a plurality of cylindrical cutters 1 are provided. The cylindrical cutters 1 are arranged perpendicular to the mounting plate 2 and are evenly distributed in an array. The cylindrical cutter 1 is cylindrical in shape and is fixedly mounted on the mounting plate 2. The mounting plate 2 is provided with a fixing hole 3. The mounting plate 2 is fixedly connected to a cylinder through the fixing hole 3. The mounting plate 2 and the cylindrical cutter 1 are moved up and down by controlling the cylinder to cut the loaded lithium battery material into blocks. After cutting, the lithium battery material is in a compacted state. The circular holes between the blocks can ensure the contact between the material and the external atmosphere during sintering, suppress the lithium / nickel mixing phenomenon during the sintering process, and improve the electrochemical properties of the material.

[0022] like Figure 4The diagram below shows the structure of a conventional cutter. This cutter leaves a small gap between the material and the atmosphere after cutting, resulting in insufficient contact. Furthermore, the material stability after cutting is poor. During subsequent rail transport into the furnace, vibrations can easily cause the cut pieces to collapse, blocking the gap and affecting product quality.

[0023] The cylindrical compacting cutter of this application creates circular holes in the material after cutting. The gaps between the materials at the bottom of the cut pieces are also circular holes, which allows for more complete air contact. The material is simply pressed into cylindrical holes, rather than being cut into multiple pieces like with existing cutters. This prevents the cut pieces from collapsing during transportation, significantly improving their stability.

[0024] The cylindrical cutter 1 is detachably connected to the mounting plate 2, for example, by a threaded connection. By replacing the cutter assembly with different heights, the compaction of the cut material can be adjusted. The shorter the cutter assembly, the tighter the material compaction. Conversely, the taller the cutter assembly, the looser the material compaction.

[0025] The cylindrical cutters 1 are arranged in a square array, with a total of 16.

[0026] Example 2

[0027] like Figure 2 In addition to Example 1, the cylindrical cutter 1 features a pointed tip at its top, which increases the speed of material removal during slicing and reduces cutting resistance. The outer surface of the cylindrical cutter 1 at the point of contact with the mounting plate 2 is truncated into a cone shape. This ensures that the sliced material remains in sufficient contact with the atmosphere, and provides enhanced anti-collapse effectiveness.

[0028] Example 3

[0029] like Figure 3 Based on Example 1, the cylindrical cutter 1 is multi-segmented, with the outer surface of the connecting sections forming a truncated cone. During the slicing process, the material becomes increasingly compacted due to pressure, increasing the resistance to the cutter's movement. By making the cylindrical cutter 1 multi-segmented, with the outer surface of the connecting sections forming a truncated cone, this can further reduce the resistance to slicing and improve production efficiency. The diameter of the front section of the cutter should not be too small, otherwise it may result in insufficient contact with the atmosphere.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
