Automatic roll changing mechanism and automatic roll changing device

Abstract

The invention discloses an automatic roll changing mechanism and an automatic roll changing device. The roll changing mechanism comprises a passing roller assembly, a passing roller horizontal movingassembly and a rotating assembly. The passing roller assembly comprises a first passing roller and a second passing roller which are arranged in parallel, a clearance exists between the first passingroller and the second passing roller, a material belt released from a work material roll can penetrate the clearance, the material belt released by the work material roll is arranged on the first passing roller and / or the second passing roller in a winding manner, and then the first passing roller and / or the second passing roller are / is used for tensioning. The passing roller horizontal moving assembly is used for driving the passing roller assembly to move horizontally towards a standby material roll of a roll releasing mechanism during when roll changing is needed so that the passing rollerassembly can get close to the standby material roll. The rotating assembly is used for driving the passing roller assembly to rotate so that the passing roller assembly can press the material belt released by the work material roll onto the standby material roll, and the material belt released by the work material roll can be connected with the material belt on the standby material roll. By meansof the automatic roll changing mechanism and the automatic roll changing device, the structure is simple, the automatic roll changing efficiency is good, and accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and in particular relates to an automatic roll changing mechanism and an automatic roll changing device. Background technique [0002] In the production process of lithium batteries, automatic winding of cathode / anode sheets and separators is required. When the pole piece and diaphragm material rolls are used up, it is necessary to start the spare material roll to complete the automatic roll changing function. The automatic roll changing device can realize the cutting and separation of the strip in use and its roll, and at the same time connect the front end of the spare roll to the tail end of the strip in use by adhesive tape. [0003] In the prior art, the structure of the pole piece and diaphragm automatic roll changing device is relatively complicated, the automatic roll changing process is relatively complicated, and the automatic roll changing efficiency is low.
