Sealing effect；Outer cover B is nonmetallic outer cover, and processing easy to form is waterproof.There are water-stop, the right flank of water-stop inside outer cover B
Outer cover A is close in portion, can play waterproof action.There are outer wing, inner wing on outer cover B, and the round and smooth protrusion of outer wing position and outer cover A are mutually
Cooperation, therefore outer wing, inner wing are to play double shielding in axis, prevent water or dust from entering in bearing.
The utility model reached it is following the utility model has the advantages that
The utility model structure is simple, convenient for production；The structure of anti-tear cylinder effectively improves carrying roller cylinder and adhesive tape
The form of CONTACT WITH FRICTION causes tearing to damage on adhesive tape without sharp and corner angle, extends the service life of adhesive tape to reduce because of glue
It is lost caused by band tearing；By the small gap of inner gear inner hole and axis, inner barrel bring due to corrosion, operating is avoided
Particulate matter enters bearing, ensure that the dustless operation of bearing, prolongs the service life；Using the labyrinth seal structure of oiling, revolving
During turning, cavity combination oiling labyrinth seal can stop external dust to enter Bearing inner；Using water-stop, prevent water from entering
Bearing inner.
