Description

TECHNICAL FIELD

BACKGROUND

[0002] The silent sponge tire refers to the silent sponge attached to the inner wall of the tire, and the porous material properties of the sponge are used to absorb the resonance generated by the tire with the ground during driving to reduce the impact of noise and achieve the effect of optimizing noise and achieving silence.

The silent sponge is often attached to the inner wall of the tire in sections, and the two ends of the attached silent sponge have connecting ports. The connecting ports are currently mostly vertical structures and the side of the port is not coated with glue and is not connected to each other. During high-speed driving, the tire interior will generate a large wind resistance, and the corresponding unconnected ports will have a risk of falling off based on the wind resistance, thereby affecting driving safety. Therefore, the applicant has applied for a utility model patent technology with application number 202223220436.0 and the name of "a silent sponge tire", which proposes three types of ports and splicing forms to connect the ports to each other to reduce the impact of wind resistance and reduce the risk of falling off.

Therefore, it is of great significance to provide an efficient, accurate, and automated industrialized and automated silent sponge tire that can realize glue coating on the side of the joint port of the silent sponge.
