Bare tire bead winding method and tire bead winding system

Abstract

The invention provides a bare tire bead winding method. The bare tire bead winding method comprises the following steps that a storage roller wound with a strip is reversely rotated for discharging, and the strip is conveyed and fed towards a roller part; when a material head of the strip is conveyed to the roller part, the roller part is rotated to automatically wind the strip with the required length to the roller part, and the tail part of the strip with a certain length is reserved below a bare tire bead; when a winding ring part is positioned at the initial position, the bare tire bead isinserted into the winding ring part from a notch part and is attached to the tail part of the strip, and the end face of the bare tire bead is perpendicular to the end face of the winding ring part;and meanwhile, the winding ring part and the bare tire bead are rotated so as to wind the strip to the bare tire bead. The invention further provides a tire bead winding system for winding by utilizing the bare tire bead winding method. Therefore, the bare tire bead winding method and system can realize full automation, material waste is avoided in the whole process, the winding stability is high,and the efficiency is high.

Description

technical field [0001] The invention relates to the field of tire production auxiliary equipment, in particular to a bare bead winding method and a bead winding system. Background technique [0002] As a component of the tire, the bead supports the fastening force between the tire and the rim, maintains and seals the air pressure inside the tire, and plays an important role in the cushioning and adjustment safety of the sidewall of the tire. [0003] Generally, the bead includes a bare bead and a strip, wherein the bare bead is a structure formed by arranging single-core glued steel wires according to a specific cross-sectional shape, and its cross-sectional shape is usually roughly hexagonal. In the subsequent process, It is very important to maintain the cross-sectional hexagonal shape. In the existing bead, the strip is wound onto the bare bead through the bead winding system. Specifically, the ring part in the bead winding system is driven by the driving device to rotat...

Problems solved by technology

In the existing bead, the strip is wound onto the bare bead through the bead winding system. Specifically, the ring part in the bead winding system is driven by the driving device to rotate. During this process, the winding device is wrapping the strip While winding on the bare bead, the strip is wound on the roller part set on the end surface of the winding ring for storage. The strip will be wound on the roller part for multiple turns. After the strip is cut by the cutting mechanism, the winding ring continues to rotate And release the multi-turn strip that has been wound on the roller part, so that the strip stored on the roller part continues to wrap the bare tire bead, but this operation requires at least one manual to pull the strip head wound on the roller part If the tape is pulled out and pasted on the bare bead, due to the high viscosity of the tape, the tape wound on the roller part for multiple turns will stick together, so that the pulling action cannot be completed quickly, which wastes manpower and the production efficiency is not high. low stability

[0004] Under normal circumstances, before the material head of the strip is manually pulled out and pasted on the bare bead, a part of the material will be subtracted to ensure the quality of the joint, which will cause waste
