The utility model discloses a transitional plate for a battery heat shrinkage film packaging machine. The transitional plate comprises a transitional plate body (1), an further comprises a transitional plate air cylinder (3) which is arranged on a workbench (2) of the battery heat shrinkage film packaging machine, wherein a piston rod of the transitional plate air cylinder (3) is fixed with the transitional plate body (1); two symmetrical elastic sheets (4) are protruded on the rear end of the transitional plate body (1); and each elastic sheet (4) inclines towards a width centre line of the transitional plate body (1). The transitional plate for the battery heat shrinkage film packaging machine can avoid the condition that the bulk batteries can not enter a sleeve chamber of the heat shrinkage film as an opening on the front end of the heat shrinkage film is too small.
