The utility model belongs to cigarette production equipment technical field discloses a kind of tipping paper curling device.The tipping paper curling device includes rack, guide plate component, paper scraping component and adjusting roller component, guide plate component is fixedly installed on rack, for guiding tipping paper;Paper scraping component is set in the downstream of guide plate component, and paper scraping component includes cutter shaft and doctor blade, cutter shaft is fixedly arranged on rack, and doctor blade is arranged along the axial direction of cutter shaft, and doctor blade is used to scrape tipping paper;Adjusting roller component includes fastening ring, connecting shaft and first paper guide roller, fastening ring is rotatably arranged on cutter shaft and is fixedly connected with connecting shaft, first paper guide roller is sleeved on connecting shaft and is rotatably connected with connecting shaft, and first paper guide roller is located between guide plate component and paper scraping component, and it can make the included angle between tipping paper and cutter shaft be acute, to solve the roughness of tipping paper surface processing effect, enhance the bonding firmness of tipping paper and glue.

The utility model relates to the lithium battery pole piece production technical field, more particularly, provide a combined pole piece drying oven, including hot -blast device and heating roller subassembly, heating roller subassembly includes a plurality of heating roller, heating roller is used for even heating pole piece, pole piece surrounds two heating rollers and forms s type's running path in turn, and hot -blast device sets up in the both sides of running path. Through heating roller and pole piece contact heat conduction heating drying to pole piece, make pole piece and heating roller contact's position all even heating, reduce the edge of pole piece active material occurrence curling phenomenon's occurrence, and because pole piece surrounds heating roller and formed s type's running path, to pole piece with the reverse curve state heating can make pole piece's different parts interact when deformation, dispersive uneven stress, thereby avoided a certain part excessive stress, reduced the overall deformation makes pole piece not easy to occur bending and wrinkle.
