Attaching assembly, equipment and method for applying sound damper to inner surface of tire

Abstract

The invention discloses an attaching assembly for applying a sound damper to the inner surface of a tire. The attaching assembly comprises a material receiving component, used for fixing a material head of the sound damper and storing a material, a pressing piece, used for pressing the material tail of the sound damper on the inner surface of the tire; and a first driving source, used for providing power to drive the material receiving component to rotate, wherein when the material receiving component receives the sound damper, the material head of the sound damper is fixed firstly, and then the first driving source drives the material receiving component to rotate so as to wind the sound damper into a roll; and when the sound damper is attaching, the sound damper wound into the roll may be released to attach the sound damper to the inner surface of the tire. The brand-new attaching assembly provided with the material receiving component, the first driving source and the pressing piece is designed, so that the strip-shaped sound damper is automatically received, wound into the roll, and unwound and attached, and the technical effects of being simple in structure, convenient to use, low in cost, high in mute material attaching quality and the like are achieved.

Description

technical field [0001] The invention relates to the field of tire production auxiliary equipment, in particular to a mechanical equipment for producing silent tires. In particular, it relates to a bonding assembly, a bonding device and a bonding method for applying a sound dampening member for reducing tire noise to the inner surface of a tire. Background technique [0002] With the popularization and promotion of new energy vehicles such as electric vehicles, traditional tires can no longer meet the needs of new energy vehicles for high-end silent tires due to their high tire noise. In recent years, domestic and foreign tire manufacturers have devoted themselves to the research and development of silent tires, and some car companies have equipped their new energy vehicles with silent tires. But when making tire, it is an unavoidable problem how to make mute materials with reducing tire noise, such as sponge, foam, etc. inside the tire. The applicant conducted research on ...

AI Technical Summary

Problems solved by technology

However, the inclined guide groove has a complex structure, and the anti-noise strip is difficult to handle once it is blocked in the inclined guide groove, and the helically inclined guide groove is difficult to manufacture, and the cost is high; It is easy to slip in the middle, which makes it difficult to accurately locate the noise band; and the overall equipment is large in size, and the energy consumption required for equipment operation is high (power consumption, gas consumption, etc.)
