[0001] The utility model relates to the technical field of bottle mouth plastic heat shrink film equipment, in particular to a bottle mouth intelligent plastic heat shrink film equipment. Background Art

[0002] The bottle mouth intelligent plastic heat shrink film equipment is used to put heat shrinkable caps on the bottle mouths of bottle-shaped, can-shaped, cylindrical and cup-shaped products, and heat the heat shrinkable caps to shrink them tightly on the bottle mouth. It is commonly used in the heat shrinkage of PVC caps on the filling lines of wine, white wine, fruit wine and tea oil.
