Description

TECHNICAL FIELD

[0001] The utility model belongs to the battery production and manufacturing technical field, specifically for a kind of unwinding device and its roll change support mechanism. BACKGROUND

[0002] In the production and manufacturing process of battery cell, the pole piece is continuous strip, and the continuous feeding is realized by adopting the mode of roll unwinding. In order to reduce the frequency of roll change, it is required to store longer pole piece strip in the roll, that is, the existing pole piece roll has the characteristics of large roll diameter and heavy weight, therefore, for the pole piece roll, a horizontal unwinding device with two end supports is needed. At the same time, since the two ends of the roll are provided with support structures, there is a positional interference between the support structures and the roll during roll change, therefore, in the existing horizontal unwinding device, at least one of the support structures at the two ends needs to be provided as a movable support structure.

[0003] The existing movable support structure is mostly a translational support structure, which is integrally installed on a linear guide rail and is driven to move horizontally by a driving mechanism. During roll change, the translational support structure is horizontally moved out of the support station along the linear guide rail, and after the roll change is completed, the translational support structure is horizontally moved back along the linear guide rail to support the roll. However, since the translational support structure needs to move a long distance to avoid the linear guide rail, it has the disadvantage of occupying a large space. SUMMARY
