Description

Lithium battery diaphragm coating rolling equipment Technical Field The utility model relates to the technical field of lithium ion battery diaphragm coating, in particular to lithium ion battery diaphragm coating rolling equipment. Background In the lithium battery separator coating generation, the material collection of the lithium battery separator is a very important process flow. Tension control, continuous stability of high-speed collection, no stop in high-speed production, no deceleration of the material-changing roll and the like are all very complex and important technological processes. The production of current lithium electricity diaphragm and rolling equipment are in order to guarantee stability, and basically the speed is at 100 meters/minute, under the circumstances of guaranteeing stable production's quality, can improve production speed by a wide margin, but need shut down and manual work roll change when rolling equipment trades the roll, and manual work trades the roll inefficiency, and shut down trades the roll, causes the error easily, influences production efficiency, scrapps the coil stock even, and equipment use cost is high moreover. Disclosure of utility model The utility model provides lithium battery diaphragm coating and winding equipment, which can solve various problems caused by shutdown and manual winding replacement when the existing winding equipment is used for winding replacement. In order to achieve the above purpose, the present utility model provides the following technical solutions: A lithium battery diaphragm coating and winding device comprises a diaphragm conveying guide assembly, wherein a fixing plate is arranged on one side of the diaphragm conveying guide assembly, the fixing plate is driven by a left side approaching driving part to slide left and right, a pressing roller and a cutting knife which can be driven by a power part to extend towards the right side are arranged on the fixing plate, a rotatable turret is arranged on the right side of the fixing plate, a first winding shaft and a second winding shaft are respectively arranged at two opposite ends of the turret, a diaphragm material is wound on the first winding shaft or the second winding shaft along the diaphragm conveying guide assembly, automatic conversion positions of the first winding shaft and the second winding shaft can be realized through the arrangement of a rotatable turret, the first winding shaft and the second winding shaft, the diaphragm material during reel replacement is pressed through a reel-changing pressing roller assembly, the diaphragm material is adhered on a new empty reel, and simultaneously, the diaphragm material during reel replacement is cut by the corresponding cutting knife, and the substrate material is rapidly and accurately wound in a lifting and winding device under a non-stop state.
