TECHNICAL FIELD

[0002] In the rubber tire production process, the compacting process in the tread forming is crucial, which directly affects the density, flatness of the tire tread and the subsequent bonding effect with the carcass, and further determines the overall performance and service life of the tire. The tire tread compacting devices commonly used in the current industry have the problem of insufficient uniformity of compaction: some devices use single roller or flat plate compaction structure, which can only press the tread as a whole, easily leading to uneven density of the tread, and uneven wear, bulging and other hidden dangers in subsequent use. In addition, the driving system of the traditional compacting device has insufficient linkage with the compacting mechanism, when the spacing of the clamping seat is adjusted, the driving mechanism is difficult to synchronously adapt to the transmission, which easily leads to transmission lag or disconnection, further reducing the stability and continuity of compaction, and the edge of the compacting block of some devices has no protective structure, which easily scratches the surface of the tread during the compaction process, affecting the appearance and quality of the tire. These problems restrict the efficiency and quality of the tire tread compaction process, and an compacting device with reasonable structure, uniform compaction, strong adaptability and high stability is needed to solve the above problems.
