When the swing hydraulic rod is in the extended state, both the separating pressure roller assembly and the flat pressure roller are in contact with the tire tread. The pre-pressure roller assembly can first pre-press and de-bubble the middle of the tire tread, and then the separating pressure roller assembly can evenly extend and press towards both ends to effectively ensure complete adhesion when the edges are bonded.

Description

Technical Field

[0001] This utility model relates to the technical field of tire tread forming equipment, and in particular to the tire tread splitting and pressing roller of the forming machine. Background Technology

[0002] During the tire forming process, the tire is thickened by repeatedly bonding rubber sheets, and the final tire shape is achieved through multiple vulcanization processes. During the bonding of soft rubber, air bubbles may exist between the rubber sheet and the tire body. If the air bubbles are not dealt with in time, the air inside the bubbles will be compressed and heated during driving, causing a sudden increase in pressure. This will cause the tread rubber to tear from the inside, resulting in a high-speed tire blowout. In extremely cold conditions, the rubber at the edge of the air bubbles will develop micro-cracks due to the difference in shrinkage rate. If the cracks expand to the critical size, it will cause a high-speed tire blowout in snowy weather.

[0003] In traditional processes, air bubble areas can develop vulcanization defects due to uneven heat conduction, turning them into permanent plastic deformation zones that continue to expand into internal cavities during subsequent use. Patent document No. 202421034139.3 proposes a relatively complete needle-punching and pressure roller degassing device. In this device, uniform and continuous needle-punching degassing is performed synchronously through front and rear sliding to achieve a general-purpose degassing effect, followed by tire stretching. However, this method cannot completely bond the rubber skin, which has certain drawbacks, damaging the rubber structure and reducing the integral structure of the rubber. This device also has a pressure-free zone in the middle of the tread, which can lead to residual air bubbles. Utility Model Content
