ABSTRACT:
A tape applying device includes a plate, front and rear swinging arms pivoted on the plate, a pressing wheel pivoted on each of the swinging arms to make an adhesive tape stick on a box, a connecting rod pivoted to both the front and the rear swing arms, a cutting mechanism interposed between the front and the rear swinging arms to sever the adhesive tape, a first restoring extension spring joined to the connecting rod, and a second restoring extension spring joined to the rear swinging arm; the front swinging arm is co-movable with the rear swinging arm and the connecting rod, and it has no extension spring directly connected thereto therefore the front pressing wheel won't produce such a reacting force as to cause a box to cave in when the box is moved rapidly onto the front pressing wheel for the adhesive tape to stick thereon.
