The collecting drawer is used to collect the scraps generated when slitting the lithium battery membrane. The collecting drawer includes a bottom plate and two baffles respectively connected to the front and rear sides of the bottom plate and protruding upward. The bottom plate is embedded in the transverse slide groove, and a pull ring is welded on the front baffle, and the upper side of the pull ring protrudes from the top of the baffle. When it is necessary to push or pull the collecting drawer, it can be operated by hooking the pull ring with an iron hook, which is convenient and labor-saving to use.
