[0002] In the production and processing of lithium batteries, coating is generally required, followed by the production of electrode sheets. After the electrode sheets are produced, they need to be dried and compacted, and then cut to reduce their volume. The electrode sheets are stacked, so cutting equipment is used to cut the negative electrode material.

[0003] The prior art patent CN221312756U discloses a cutting device for processing negative electrode materials of power batteries. When cutting the negative electrode material, the telescopic rod between the cutting frames on the main board is supported by the top plate, which pushes the cutter downward. The cutting of the negative electrode material is achieved through the cooperation between the cutter and the auxiliary block.

[0004] While the above method can cut the negative electrode material, it does not collect the residue generated during the cutting process, thus affecting the processing environment. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] First embodiment:

[0020] Please see Figure 1 and Figure 2 ,in Figure 1 This is a structural schematic diagram of a power battery negative electrode material cutting device provided by this utility model. Figure 2 This is a schematic diagram of another direction of the cutting device for the negative electrode material of a power battery provided by this utility model (the cutting table is hidden therein).

[0021] This utility model provides a cutting device for negative electrode materials of power batteries, including a main board 101, a support frame 102, and a cutting component. The cutting component includes a cylinder 103, a cutting blade 104, a hanger 105, a cutting table 106, a dust cleaning assembly 107, and an auxiliary assembly 108. The dust cleaning assembly 107 includes a connecting plate 109, a rotating shaft 110, a rotating gear 111, a first cleaning roller 112, a driven shaft 113, a second cleaning roller 114, a driven gear 115, a brush 116, a drive motor 117, a collection box 118, and a handle 119. The auxiliary assembly 108 includes a sliding plate 120, a guide cylinder 121, and a guide rod 122. This solution solves the problem in existing technologies where residue generated during the cutting process is not collected, thus affecting the processing environment.

[0022] In this specific embodiment, the mainboard 101 is fixedly connected to the support frame 102 and located above the support frame 102; the hanger 105 is fixedly connected to the mainboard 101 and located on the side of the mainboard 101 away from the support frame 102; the cylinder 103 is fixedly connected to the hanger 105 and located on the hanger 105; the cutting blade 104 is fixedly connected to the cylinder 103 and located on one side of the cylinder 103; the cutting table 106 is fixedly connected to the mainboard 101 and located between the hangers 105; the dust removal component 107 is located on one side of the cutting table 106; the auxiliary component 108 is located on the side of the cutting blade 104 away from the cutting table 106; and the cutting table 106 is provided with a cutting hole 123 to facilitate cutting. Meanwhile, the residue generated during the cutting process falls downwards. The auxiliary component 108 is used to improve the stability of the cutting blade 104 during the cutting process, thereby improving the cutting quality of the negative electrode material. First, the cylinder 103 is activated, which drives the cutting blade 104 to extend and retract, causing the cutting blade 104 to move downwards and insert into the cutting hole 123 to cut the negative electrode material on the cutting table 106. The residue generated during the cutting process will fall from the cutting hole 123 into the collection box 118. At the same time, during the process of the cutting blade 104 inserting into the cutting hole 123, the dust cleaning component 107 will clean and collect the residue adhering to the cutting blade 104, thereby realizing the collection of residue generated during the cutting process and improving the quality of the processing environment.

[0023] Meanwhile, the connecting plate 109 is fixedly connected to the cutting table 106 and located at both ends of the cutting table 106; the rotating shaft 110 is rotatably connected to the connecting plate 109 and located between the connecting plates 109; the first cleaning roller 112 is fixedly connected to the rotating shaft 110 and located on the outer wall of the rotating shaft 110; the rotating gear 111 is fixedly connected to the rotating shaft 110 and located between the first cleaning roller 112 and the connecting plate 109; the driven shaft 113 is rotatably connected to the connecting plate 109 and located on one side of the first cleaning roller 112; the second cleaning roller 114 is fixedly connected to the driven shaft 113 and located on the outer wall of the driven shaft 113; the driven gear 115 is fixedly connected to the driven shaft 113 and located between the second cleaning roller 114 and the connecting plate 109, and the driven gear 115 meshes with the rotating gear 111. Brushes 116 are disposed on the outer walls of the first cleaning roller 112 and the second cleaning roller 114. The output shaft of the drive motor 117 is fixedly connected to the rotating shaft 110 and located on one side of the rotating shaft 110. By starting the drive motor 117, the drive motor 117 drives the rotating shaft 110 to rotate, thereby causing the first cleaning roller 112 to rotate. At the same time, the rotating gear 111 also rotates. Since the rotating gear 111 meshes with the driven gear 115, the rotating gear 111 drives the driven gear 115 to rotate. The rotation of the driven gear 115 drives the driven shaft 113 to rotate on the connecting plate 109, and also drives the second cleaning roller 114 to rotate, thereby causing the brushes 116 on the first cleaning roller 112 and the second cleaning roller 114 to rotate, cleaning the residue on the cutting blade 104.

[0024] Secondly, the collection box 118 is slidably connected to the main board 101 and located between the main board 101 and the cutting table 106. The handle 119 is fixedly connected to the collection box 118 and located on one side of the collection box 118. The main board 101 is provided with a sliding groove 124, and the collection box 118 slides in the sliding groove 124 on the main board 101. The collection box 118 is used to collect negative electrode material residue generated during the cutting process. The handle 119 facilitates pushing and pulling the collection box 118.

[0025] Furthermore, the slide plate 120 is fixedly connected to the cutting blade 104 and located on one side of the cutting blade 104. The guide cylinder 121 is fixedly connected to the hanger 105 and located on the inner wall of the hanger 105. The guide rod 122 is slidably connected to the guide cylinder 121 and located inside the guide cylinder 121. The guide rod 122 is also fixedly connected to the slide plate 120 and located on the side of the slide plate 120 away from the cutting blade 104. When the cutting blade 104 moves up and down, the slide plate 120 slides on the hanger 105, and at the same time, the guide rod 122 also slides in the guide cylinder 121, thereby ensuring the stability of the cutting blade 104 during its up and down movement and improving the cutting quality of the negative electrode material.

[0026] When using the power battery negative electrode material cutting device of this embodiment, the cylinder 103 is first activated, which drives the cutting blade 104 to extend and retract, causing the cutting blade 104 to move downward. Simultaneously, the sliding plate 120 slides on the hanger 105, and the guide rod 122 slides in the guide cylinder 121. When the cutting blade 104 is inserted into the cutting hole 123, it cuts the negative electrode material on the cutting table 106. Residue generated during the cutting process falls into the collection box 118. Next, before the cutting blade 104 is inserted into the cutting hole 123, the drive motor 117 is activated, which drives the rotating shaft 110 to rotate, thereby causing the first cleaning roller 112 to... The rotating gear 111 also rotates. Since the rotating gear 111 meshes with the driven gear 115, the rotating gear 111 drives the driven gear 115 to rotate. The rotation of the driven gear 115 drives the driven shaft 113 to rotate on the connecting plate 109, and also drives the second cleaning roller 114 to rotate. This causes the brushes 116 on the first cleaning roller 112 and the second cleaning roller 114 to rotate, cleaning the residue adhering to the cutting blade 104 and causing the residue to fall into the collection box 118. This achieves the collection of residue generated during the cutting process, improves the quality of the processing environment, and also prevents the residue on the cutting blade 104 from affecting the cutting quality.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
