[0002] Lithium batteries can be roughly divided into lithium metal batteries and lithium-ion batteries; lithium-ion batteries do not contain metallic lithium and are rechargeable, which has led to a wide expansion in the use of lithium batteries today; currently, during the production process of existing lithium battery negative electrode sheets, due to reasons such as low bonding strength on the negative electrode sheets, it is easy for electrode particles to adhere to the pressing roller, thereby affecting the subsequent rolling processing of the negative electrode sheets. Existing technology generally sets scrapers on the outside of the pressing roller to clean the electrode particles, but after scraping off the electrode particles, the electrode particles will be scattered everywhere and cannot be well collected in a centralized manner. Therefore, the existing structure needs to be modified and upgraded. Utility Model Content
