Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to a self-cleaning device for a slitting blade. Background Technology

[0002] Fine aluminum shavings generated during battery electrode slitting adhere to the surface of the slitting blades, and when soaked in alcohol, they form scale. This aluminum scale accumulates between the slitting blade body and the blade disc, causing the slitting blade to jam, chip, and ultimately resulting in burrs and damage during electrode tab slitting. To address this issue, felt is commonly used to clean the slitting blades, but this cannot completely prevent aluminum scale buildup and requires periodic replacement and inspection, which is quite inconvenient. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a self-cleaning device for slitting blades. This device can prevent the accumulation of impurities during the cleaning process of the slitting blade with felt, ensuring the stable operation of the slitting blade over a long period of time.

[0004] In view of this, the present invention provides a self-cleaning device for a slitting knife, comprising:

[0005] The blade holder body has a blade groove for the slitting blade to extend into;

[0006] The cleaning component is located in the blade groove and is in contact with the slitting blade;

[0007] An alcohol inlet is installed on the blade sheath body and is used to wet the cleaning components.

[0008] Negative pressure channel, which is located in the tool holder body and communicates with the tool groove;

[0009] Negative pressure components are used to remove impurities from cleaning components through negative pressure channels.

[0010] In this technical solution, during the slitting process, alcohol wets the cleaning component through the alcohol inlet, and the cleaning component wets and cleans the surface of the slitting blade. As the slitting blade rotates, impurities such as aluminum shavings on the slitting blade accumulate on the cleaning component. At this time, the negative pressure component can remove and clean the impurities accumulated on the cleaning component through the negative pressure channel, keeping the cleaning component clean.

[0011] In the above technical solution, the main body of the tool holder is generally arc-shaped, and the tool groove connects the two ends of the main body of the tool holder.

[0012] In the above technical solution, the cleaning component further includes two first cleaning blocks respectively disposed at both ends of the blade sleeve body and a second cleaning block disposed in the blade groove, wherein the second cleaning block is wetted by the alcohol inlet component.

[0013] In the above technical solution, the alcohol inlet includes an alcohol filling channel and an alcohol tube. The alcohol filling channel is located on the outer wall of the blade sleeve body and is connected to the blade groove. One end of the alcohol tube is connected to the alcohol filling channel, and the other end of the alcohol tube is located outside the blade sleeve body.

[0014] In the above technical solution, the second cleaning block is further provided in the knife groove at the opening of the alcohol filling channel.

[0015] In the above technical solution, furthermore, the first cleaning block and the second cleaning block are provided with grooves that contact the slitting blade.

[0016] In the above technical solution, furthermore, both ends of the blade sheath body are provided with negative pressure channels. The negative pressure channel includes an external groove, a negative pressure cavity and a connecting groove. The negative pressure cavity is set in the blade sheath body, the external groove is set on the outer wall of the blade sheath body, the external groove is connected to one end of the negative pressure cavity, and the connecting groove is set on one side of the first cleaning block. The connecting groove is connected to the end of the negative pressure cavity away from the external groove.

[0017] In the above technical solution, the negative pressure component further includes a chip removal tube, one end of which is connected to an external groove, and the other end of which extends to the outside of the blade sleeve body to connect to the negative pressure device.

[0018] In the above technical solution, the chip removal tube is further described as a flexible tube.

[0019] In the above technical solution, both the first cleaning block and the second cleaning block are made of wool felt.

[0020] The beneficial effects of the utility model are:

[0021] 1. Through the cooperation of the cleaning component and the alcohol inlet component, the slitting blade can be wetted and cleaned in time during the slitting process. Furthermore, through the cooperation of the negative pressure component and the negative pressure channel, the impurities accumulated on the cleaning component can be removed in time, avoiding the accumulation of aluminum shavings during the cleaning process of the slitting blade. This ensures the stable operation of the slitting blade for a long time, thereby reducing the scrapping of electrode sheets caused by damage to the slitting blade due to aluminum shavings accumulation, and eliminating the need for frequent replacement of the cleaning component.

[0022] 2. By designing the blade sleeve body into an arc shape, it is easy to disassemble and assemble the slitting blade. In addition, the cleaning components are set as a first cleaning block at both ends of the blade sleeve body and a second cleaning block in the blade groove. In this way, the drainage cleaning components can wet the surface of the slitting blade, while the first cleaning block can remove impurities from the surface of the slitting blade. By cleaning the slitting blade at multiple points, the cleaning effect is good.

[0023] 3. By configuring the negative pressure channel into an external groove, a negative pressure chamber, and a connecting groove, and connecting the negative pressure device to the external groove through the chip removal pipe, the negative pressure device can sequentially suck out the impurities accumulated on the first cleaning block by starting the negative pressure device, passing through the connecting groove, the negative pressure chamber, the external groove, and the chip removal pipe. This extends the service life of the cleaning parts and further ensures the long-term stable operation of the slitting blade. Attached Figure Description
