[0031] like Figures 1-7 The electrode slitting device with dust removal function shown includes a frame 1 and a cutting blade set on the frame 1. The frame 1 is also provided with a transmission roller 4 for horizontally transporting the electrode. The cutting blade is a disc cutter 2, which is mounted on a transmission shaft 3. The transmission shaft 3 is mounted on the frame 1 in a horizontal rotation.

[0032] The drive roller 4 is mounted horizontally on top of the frame 1;

[0033] Similar to existing technologies, the frame 1 is also equipped with a drive mechanism for rotating the transmission shaft 3. The drive mechanism includes a motor 5 and a transmission mechanism 6. The motor 5 drives the transmission shaft 3 to rotate through the transmission mechanism. In this embodiment, the transmission mechanism 6 is a belt drive mechanism.

[0034] The frame 1 is also equipped with a dust hood 7 that covers the disc cutter 2. A guide cavity is formed between the disc cutter 2 and the dust hood 7. The dust hood 7 is provided with an upper suction pipe 8 that communicates with the guide cavity. It should be noted that the upper suction pipe 8 is provided in front of the dust hood 7 and also in the rear of the dust hood 7. That is, the upper suction pipe 8 is provided with at least two sets. Those skilled in the art should understand that the front and rear of the dust hood 7 are relative to the electrode feeding direction and the electrode discharging direction. The front of the dust hood 7 is the electrode feeding direction, and the rear of the dust hood 7 is the electrode discharging direction.

[0035] The transmission roller 4 has a dust removal ring groove 40, which is opposite to the disc cutter 2. The frame 1 is provided with a lower suction pipe 9 opposite to the dust removal ring groove 40. Like the upper suction pipe 8, the lower suction pipe 9 is also provided with at least two sets. One set of lower suction pipe 9 is located in front of the transmission roller 4, and the other set of lower suction pipe 9 is located behind the transmission roller 4.

[0036] During operation, in addition to facilitating the cutting of electrode sheets, the dust removal ring groove 40 also collects dust and debris, and guides the dust and debris. The dust removal hood 7 and the upper suction pipe 8 further enhance the dust removal and debris removal effect, thereby making the surface of the cut electrode sheet smooth.

[0037] Preferably, in order to further enhance the dust removal effect, a lower dust suction hood 10 is also provided on the frame 1. The lower dust suction hood 10 is installed on the frame 1, and an electrode passage area is formed between the lower dust suction hood 10 and the dust removal hood 7. The lower dust suction hood 10 is opposite to the dust removal ring groove 40. The lower dust suction pipe 9 is installed on the lower dust suction hood 10 to further facilitate the collection of dust and waste. Preferably, the upper surface of the lower dust suction hood 10 is flat to facilitate the support of the electrode.

[0038] Preferably, the dust removal ring groove 40 is a V-shaped groove, and the width of the dust removal ring groove 40 gradually increases from the side closer to the axis of the transmission roller 4 to the side farther away from the axis of the transmission roller 4.

[0039] In some preferred embodiments, the disc cutter 2 is provided with air blades 11 on both ends, and at least two sets of air blades 11 are provided. At least two sets of air blades 11 are circumferentially sewn onto the end faces of the disc cutter 2. During the rotation of the disc cutter 2, the disturbance to dust and chips is increased, which facilitates the adsorption and collection of dust and chips and increases the electrode cutting effect.

[0040] Based on any of the above embodiments, preferably, the dust removal ring groove 40 is provided with a fan blade 12 along the radial direction of the transmission roller 4. The fan blade 12 is provided in multiple sets and the multiple sets of fan blade 12 are circumferentially distributed in the dust removal ring groove 40, which further facilitates the increase of cutting effect.

[0041] like Figure 8As shown, based on the above embodiments, in some preferred embodiments, a mounting ring 13 is also included. The mounting ring 13 is rotatably sleeved outside the transmission roller 4 and located inside the dust removal ring groove 40, and the impeller blade 12 is mounted on the mounting ring 13 to further increase the dust removal effect.

[0042] Based on any of the above embodiments, preferably, the dust cover 7 is further provided with a cutter wiping component 14, which is used to wipe the disc cutter 2. On the one hand, it prevents waste or dust from adhering to the outer surface of the cutter and thus affecting the processing accuracy. On the other hand, it helps to reduce the temperature of the disc cutter 2.

[0043] Based on any of the above embodiments, preferably, the cutter wiping component 14 includes a mounting frame 140 and an adsorption component 141 mounted on the mounting frame 140. The adsorption component 141 can be made of sponge or other materials with certain adsorption functions. In this embodiment, the adsorption component 141 is wool felt. The mounting frame 140 is mounted on the dust cover 7 through the adjustment component 15, and the distance between the adsorption component 141 and the disc cutter 2 is adjusted through the adjustment component 15, thereby facilitating the adjustment of the cleaning and cooling effect on the disc cutter 2.

[0044] Based on any of the above embodiments, preferably, the mounting bracket 140 has an extension column 1400, which is laterally slidably mounted on the dust cover 7 and has a portion extending beyond the dust cover 7. The adjusting assembly 15 includes a pressure plate 150 and a locking member 151. The pressure plate 150 is mounted on the extension column 1400 extending beyond the dust cover 7, and the locking member 151 is rotatably mounted on the pressure plate 150. The locking member 151 is connected to the dust cover 7 by a thread. Rotating the locking member 151 adjusts the distance between the mounting bracket 140 and the disc cutter 2. A first elastic member 152 is sleeved on the outer side of the extension column 1400. The first elastic member 152 is a spring, which is located between the pressure plate and the dust cover.

[0045] Based on any of the above embodiments, preferably, it also includes an alcohol container 16 and a liquid guide tube 17. The alcohol container 16 is located above the adsorption element 141, and the alcohol in the alcohol container 16 is dripped onto the adsorption element 141 through the liquid guide tube 17. The alcohol container 16 contains alcohol, and the alcohol is adsorbed onto the adsorption element 141 through the liquid guide tube 17. On the one hand, it is convenient to wet the adsorption element 141 to adsorb dust and waste, and on the other hand, it is convenient to cool down the cutter and remove static electricity from the cutter.

[0046] Based on any of the above embodiments, preferably, the liquid guide tube 17 has a regulating valve 18, which is used to regulate the flow rate of alcohol in the liquid guide tube 17. Preferably, the liquid guide tube 17 is provided with a transparent portion 170 to facilitate observation of the flow rate.

[0047] Based on any of the above embodiments, preferably, the height of the transmission roller 4 on the frame 1 is adjustable.

[0048] Specifically, in this embodiment, the two ends of the transmission roller 4 are respectively mounted on the lifting block 19. The frame 1 is provided with a vertical slide groove 100. The lifting block 19 is vertically slidably mounted in the slide groove 100. The bottom of the lifting block 19 and the slide groove 100 is provided with a second elastic element 20. The second elastic element 20 in the figure is a spring, but it can also be other deformable components. The frame 1 is also provided with a lifting adjustment element 21. The lifting adjustment element 21 is mounted on the frame 1 and is used to press against the top of the lifting block 19. The lifting adjustment element 21 is mounted on the frame 1 by means of threads, and the lower end of the lifting adjustment element 21 abuts against the lifting frame. Rotating the lifting adjustment element 21 changes the deformation of the second elastic element 20, so that the position of the lifting block 19 in the vertical direction changes. When the lifting block 19 is located in the slide groove 100, the second elastic element 20 is in a compressed state. On the one hand, the electrode sheet can be cut by adjusting the lifting block 19 to the highest position on the frame 1.

[0049] like Figure 2 As shown, in some embodiments, based on the above embodiments, a side fixing member 22 can be detachably installed on the frame 1. The side fixing member 22 has a portion extending into the slide groove 100 and is used to abut against the side of the lifting block 19, thereby increasing the stability of the transmission roller 4 during the cutting process.
