The utility model provides a tire building machine, which aims to solve the problem that the tire building machine for passenger radial tires in the prior art has poor fitting precision and stability for fitting and winding belt drums of different inch levels.

A tire building machine as shown in fig. 1 to 8, comprising a winding head 10, a plurality of attaching templates and a belt drum 30, the attaching templates being each disposed obliquely, and at least two attaching templates being disposed at different heights; the belt drum 30 is movably disposed on the output side of each of the laminating die plates and the winding head 10, and the moving locus of the belt drum 30 is vertically disposed between the conveying locus of the laminating die plates so that the laminating die plates are always tangent to the surface of the belt drum 30 when laminating is performed.

According to the embodiment, through optimizing and improving the moving mode of the belt drum 30, the moving track line of the belt drum 30 is arranged to be perpendicular to the conveying track line of the laminating template, so that when the belt drum 30 moves up and down in an inclined mode to be matched with different laminating templates, the laminating template and the belt drum 30 can always keep a tangential relation, and laminating precision and stability are guaranteed. Meanwhile, even when the tire specification changes, the diameter of the belt drum 30 changes along with the change, the contact point between the bonding template and the belt drum 30, namely the bonding position of the sizing material and the drum, can be ensured not to change, so that the bad influence on the bonding precision caused by the change of the specification due to the change of the bonding position can be effectively avoided, and the bonding precision and the stability are ensured to be always kept at higher levels.

In this embodiment, the laminating template adopts the mode of fixed setting, and the laminating template can not swing or remove promptly, and its cooperation with the belt drum 30 is realized through the removal of belt drum 30, like this, the laminating template of fixed angle is simpler in structure compared with swing formula laminating template, has better stability to owing to do not have the swing action in the production process, therefore can improve laminating efficiency.

Alternatively, the transfer trajectory of the conformable template forms an angle of 10 ° -20 ° with the horizontal plane, and correspondingly, the belt drum 30 movement trajectory forms an angle of 10 ° -20 ° with the vertical plane. Thus, the adaptability of the bonding can be ensured, and the bonding requirements under various conditions can be met.

Preferably, the transfer trajectory of the conformable template forms an angle of 12 ° with the horizontal, and correspondingly, the belt drum 30 movement trajectory forms an angle of 12 ° with the vertical.
