AI Technical Summary
In the existing technology, the shoulder profile of the large-diameter forming drum does not match the rigid surface of the cylindrical pressure roller, which makes it difficult for the inner liner and the carcass cord to achieve a tight bond at this position, resulting in uncompacted gaps that affect the quality of the formed tire blank.
Design a pressing device including two movable pressure rollers, each pressure roller having a pressing groove adapted to the shoulder of the forming drum, forming a continuous annular structure. By pressing the pressing groove with the shoulder of the forming drum, the inner liner layer is ensured to be tightly attached to the tire carcass. The pressure rollers are flexibly adjusted and stably fixed by a support shaft, locking element and drive assembly.
It significantly improves the contact accuracy and bonding performance during the pressing process, avoids gaps or air trapping, enhances the structural integrity and quality consistency of the blank, strengthens the equipment's adaptability to molding drums of different specifications, optimizes the pressing process, and improves production efficiency and process stability.

Abstract
Claims
1. A press device for press fitting with a forming drum (200), characterized in that, include: Two pressure rollers (1) extend along the axial direction of the forming drum (200), and each pressure roller (1) is movably arranged; each pressure roller (1) is provided with a pressing groove (10) adapted to the shoulder of the corresponding forming drum (200), the pressing groove (10) extends along the circumferential direction of the pressure roller (1) to form a continuous annular structure; so that the inner lining layer located at the shoulder of the forming drum (200) is tightly attached to the tire cord fabric by pressing and engaging with the shoulder of the corresponding forming drum (200) through the pressing groove (10).
2. The pressing device according to claim 1, characterized in that, The pressure roller (1) includes: The limiting section (11) and the pressing section (12) are provided, wherein the diameter of the limiting section (11) is larger than the diameter of the pressing section (12), the limiting section (11) is used to limit the fit with the end face of the molding drum (200), and the pressing section (12) is used to press fit with the side wall of the molding drum (200). The arc transition section (13) and the limiting section (11) are connected to the pressing section (12) through the arc transition section (13). The limiting section (11) is close to the end face of the arc transition section (13), and the arc transition section (13) and the pressing section (12) are close to the end face of the arc transition section (13) to form the pressing groove (10).
3. The press according to claim 1, wherein The pressing device further includes: A support shaft (2) is movably arranged and extends along the axial direction of the pressure roller (1). Each pressure roller (1) is adjustedly arranged on the support shaft (2) along the extension direction of the support shaft (2).
4. The press device of claim 3, wherein The pressing device further includes: two sets of locking members (3), each set of locking members (3) is arranged in correspondence with each of the pressure rollers (1), and each set of locking members (3) is used to lock or unlock the corresponding pressure roller (1) and the support shaft (2); Each set of locking components (3) includes at least one locking component (3), which has a locked state and an unlocked state.
