With the winding ring member 22 at the initial position, the bare bead 300 is inserted from the notch 221 into the inside of the winding ring member 22 until the bare bead 300 is attached to the tail of the strip on the support plate 20, and at the same time, the roller stopper assembly 48 positions the vertical state of the bare bead 300. The end surface of the bare bead 300 inserted into the notch 221 is perpendicular to the end surface of the winding ring member 231. The initial position of the winding ring member 22 is preferably such that the cutaway portion 221 faces vertically upward.
The second drive mechanism 4 drives the bare bead 300 to rotate, and the first drive mechanism 26 drives the winding ring member 22 to rotate, to effect winding of the strip 200 onto the bare bead 300.
In summary, the winding ring device of the present invention has the roller assembly 22 disposed on the end wall of the winding ring member 22, and the tensioner 25 is disposed to rotate synchronously with the roller assembly 22, so that when the strip 200 is wound to the bare bead 300, the strip 200 has a substantially stable tension, thereby avoiding the problems of air bubbles caused by unstable strip tension, improving the winding quality, and having high versatility due to adjustable strip winding tension, and being more suitable for strips with different widths or thicknesses. The invention also provides a winding device with the winding ring device, which is convenient for semi-automatic transformation and is suitable for various production conditions. The invention also provides a tire bead winding system 100 with the winding device, and the tire bead winding system 100 can realize full automation, has no material waste in the whole process, and has high winding stability and high efficiency.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
