Extra-huge size engineering all-steel radial tire three-dimensional wrapping and attaching mechanism

Abstract

The invention relates to an extra-huge size engineering all-steel radial tire three-dimensional wrapping and attaching mechanism, which is characterized in that a swing mechanism comprises an external gear ring centering track, a positioning rotating internal ring, a swing mechanism support plate, a swing driving servo motor and a swing driving gear. The external gear ring centering track is fixedly installed at the upper plane of a motional base; the positioning rotating internal ring is movably connected to the external gear ring centering track in a rotatable way; one end of the swing mechanism support plate is fixedly connected with the positioning rotating internal ring; and the swing driving servo motor is fixedly installed on the swing mechanism support plate, and the output shaft of the swing driving servo motor penetrates through the swing mechanism support plate to be fixedly connected with the swing driving gear which is meshed with the external teeth of the external gear ring centering track. The mechanism greatly improves the quality and precision of wrapping and attaching operation, and can effectively prevent the occurrence of rolling back of adhesive strips after the adhesive strips are wrapped and attached, thereby improving the production efficiency.

Description

1. Technical field [0001] The invention relates to a wrapping mechanism for mechanical tread wrapping of rubber tires, in particular to a three-dimensional wrapping mechanism for extra-large all-steel engineering radial tires. 2. Background technology [0002] The current OTR tire tread winding device can be applied to the tread winding and compacting operation in the general specification OTR tire building process, and there are still many deficiencies in practice: mainly when the rubber strip is delivered to the application pressure roller After being cut by the cutting device, the rubber strip is prone to retreat under the action of its own tension, and it is necessary to manually guide the retracted rubber strip to the correct position, which consumes manpower; The tensile tension between the rubber strips is uneven, and when the rotating linear speed of the forming carcass does not match the linear speed of the rubber strips, the uneven tension between the rubber strips...

Problems solved by technology

[0002] The current OTR tire tread winding device can be applied to the tread winding and compacting operation in the general specification OTR tire building process, and there are still many deficiencies in practice: mainly when the rubber strip is delivered to the application pressure roller After being cut by the cutting device, the rubber strip is prone to retreat under the action of its own tension, and it is necessary to manually guide the retracted rubber strip to the correct position, which consumes manpower; The tensile tension between the rubber strips is uneven, and when the rotating linear speed of the forming carcass does not match the linear speed of the rubber strips, the uneven tension between the rubber strips will increase, resulting in low accuracy.

This kind of wrapping device can barely adapt to the wrapping process conditions required by the current general specification OTR tires. However, with the needs of my country's economic development, my country's tire companies have developed giant or even extra-large all-steel OTR tires. This type of engineering tire has a large diameter, wide section, and thick tread. The shape of the wrapping has a greater change than that of the general engineering radial tire, and the required precision is higher. Therefore, the original wrapping device can no longer meet the new process production requirements. It is necessary to design a tread wrapping mechanism with high wrapping precision and adaptable to the wrapping shape of new technology
