Tire blank press roll mechanism, as well as device and rolling method using tire blank press roll mechanism

Abstract

The invention discloses a tire blank press roll mechanism, as well as a device and rolling method using the tire blank press roll mechanism. The tire blank press roll mechanism comprises a connection frame, and rollers, a radial driving mechanism, a swinging driving mechanism and a pivot connection piece which are arranged on the connection frame, wherein the swinging driving mechanism is controlled by a programmable logic controller (PLC) system. The combined press roll device using the tire blank press roll mechanism is provided with an anti-package press roll mechanism, a tread press roll mechanism and a tire shoulder press roll mechanism which are used for rolling different regions of a tire blank and executing the rolling operations at the same time. According to the tire blank press roll mechanism, the rollers do profiled rolling motion along the contour of the tire blank in a servo driving mode controlled by the PLC system, so that the rolling quality is improved; furthermore, during the rolling, multiple groups of press roll mechanisms run synchronously, and the rolling efficiency is improved.

Description

technical field [0001] The invention relates to a pressure roller structure used on a tire building machine and a tire blank rolling method, belonging to the field of rubber machinery. Background technique [0002] In the manufacturing process of the existing all-steel radial and semi-steel car tires, after the tire embryo is turned up on the building drum, it needs to be pressed by a combined rolling device to realize the multi-layer belt structure and the tread, tire. Fitting of barrel parts. The quality of tire rolling will directly affect the subsequent vulcanization process and tire performance. [0003] attached figure 1 It is the cross-sectional profile of the tire blank. The current commonly used structure is to simultaneously roll the A, B, and C regions of the tire blank by multiple sets of pressure roller mechanisms. For example, the previously published patent 200910020251.5 is titled tire building machine combined rolling device and its method. The device ha...

Problems solved by technology

[0005] In the above-mentioned prior art, the movement of the pressure roller is driven by the cylinder, and when the cylinder is inflated, it is pushed to the bottom, so the middle process of the rolling movement is difficult to control, and it is easy to cause glue shortage when rolling, especially when rolling the B area with a large curvature. or with air bubbles

On the other hand, although the flap structure can ensure that the surface of the roller can be pressed against the surface of area B, it does not achieve complete profiling, which affects the rolling quality; and the flap structure is complicated to manufacture and the cost is high
