The bead winding system of the present invention with the winding device of embodiment 2 is implemented as follows: the total driving source drives the rotating shaft of the material roll 101 to rotate reversely, so as to drive the material roll 101 to discharge. After the belt 200 passes through the plurality of stock rollers 102 onto the support plate 301, the driving cylinder 74 drives the bottom plate 73 to move towards the roller assembly 32, at this time, the first driving cylinder 335 drives the supporting member 332 to move away from the damping roller 331, so that the supporting member 332 and the damping roller 331 are in an open state, and the support plate 301 passes between the supporting member 332 and the damping roller 331 and is connected with the roller member 321 under the driving of the driving cylinder 74.
Next, the tape 200 is transferred to the roller member 321 through the support plate 301, before the roller member 321 detects whether the tape 200 is already stored by the photoelectric sensor 3212, after it is ensured that the tape 200 is not stored in the roller member 321, the stub end of the tape 200 is allowed to enter the roller member 321, the first driving source drives the rotating member 62 to rotate and rotates the roller member 321 to temporarily store the tape 200 on the roller member 321, and when the encoder 103 detects that the length of the tape 200 stored in the roller member 321 reaches the length required for a single bead, the cutter mechanism 20 cuts the tape. When the cut-off tail of the strip 200 is left with a certain length and is not wound around the roller member 321, the support plate 301 is withdrawn and the tail of the strip 200 is falling on the support plate 34.
The second driving mechanism 5 drives the bare bead 300 to enter the inside of the winding ring part 3 from the notch part downwards, so that the bare bead 300 and the winding ring part 3 are crossed with each other, the bare bead 300 is driven to move downwards to the supporting plate 34 and is abutted against the tail of the strip 200 and then lifted up, the strip 200 is adhered due to the fact that the strip 200 is high in viscosity, the driving wheel assembly drives the bare bead 300 to rotate, and meanwhile, the first driving mechanism 4 drives the winding ring part 3 to rotate, so that the strip 200 on the roller part 321 is driven to be released to be wound on the bare bead 300. Due to the arrangement of the damping assembly 33, the strip 200 on the roller part 321 passes between the damping roller 331 and the supporting part 332, and the damping roller 331 and the supporting part 332 are in a relatively closed state under the action of the compression spring 335, so that the strip 200 is uniformly output with constant tension, the strip 200 wound on the bare bead 300 is ensured to have uniform tension, and the winding quality is improved.
In summary, the winding ring device 100 of the present invention has the roller assembly 32 and the damping assembly 33 disposed on the end wall of the winding ring member 3, so that when the strip 200 is wound around the bare bead 300, the strip 200 has a substantially stable tension, thereby avoiding problems such as air bubbles caused by unstable strip tension and improving winding quality. 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 with the winding device, which 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.
