Description

Rolling pinch roller device of lithium ion battery pelleter

Technical Field

The utility model relates to a lithium ion battery production facility especially relates to battery pelleter rolling pinch roller device.

Background

In the production and manufacturing process of the lithium ion battery, a rolling pinch roller device of a sheet making machine is a key process. The rolling pinch roller device is used for orderly and tightly rolling the rolled pole pieces by using the dead weight of the pinch roller. The current winding pinch roller device has poor pole roll pressing effect, complex structure and inconvenient operation. CN2013208840215 discloses a positive plate winding device for a lithium battery sheet making machine, which comprises a material receiving roller for winding a positive plate welded with a tab, and a pressing and winding assembly for pressing the positive plate wound on the material receiving roller, wherein the pressing and winding assembly is provided with a pressing roller, the pressing roller is in contact with the outermost positive plate wound on the material receiving roller, the rotating direction of the pressing roller is opposite to the rotating direction of the material receiving roller, and the linear velocity of the rotating surface of the pressing roller, which is connected with the outermost positive plate, is equal to the linear velocity of the outermost positive plate. Through setting up the pressure book subassembly, the compression roller of pressing the book subassembly can compress tightly the positive plate when the positive plate is convoluteed on the receiving roll, prevents that the positive plate from convoluteing the pole piece that forms on the receiving roll and rolling up the external diameter size of both sides and differed too greatly for the positive plate is more even at the in-process atress of coiling the receiving roll, avoids the welding of positive plate to have one side of utmost point ear to appear breaking because of the atress is too big. CN2015200031226 discloses a lithium cell pelleter's coiling mechanism with a plurality of compression rollers, including the frame, the frame is equipped with receipts material roller and support, and the support is equipped with a plurality of pressure book subassemblies, presses a book subassembly to be equipped with adjusts pole and compression roller, and the compression roller rigid coupling is in the regulating rod tip, and the compression roller corresponds receipts material roller setting, and the one end linking bridge of compression roller is kept away from to the regulation pole, and the support is equipped with the locking piece that is used for the fixed stay pole. The compression roller of a plurality of pressure book subassemblies is when the positive plate is convoluteed on the receiving roll, compress tightly the positive plate from a plurality of directions, prevent that the positive plate from convoluteing the external diameter size that the pole piece that forms was rolled up both sides on the receiving roll from differing too greatly, make the positive plate at the in-process atress of coiling the receiving roll even, be difficult to appear the too big condition of one side atress that the positive plate welded utmost point ear, thereby effectively avoid the one side that the positive plate welded utmost point ear to appear cracked problem because of the atress is too big, and can adjust the pressure between compression roller and the pole piece book through adjusting the pole.

The defects of the two patents are that the structure is complex and the operation is inconvenient.
