Description

Technical Field

[0001] The utility model relates to the field of self-repairing tires, in particular to a tire inner wall separated bidirectional glue spraying device. Background Art

[0002] Ordinary tires are polished, dusted, hot-dried, and centrifugally high-temperature glued to form a 5-7mm polymer coating inside the tire, thereby achieving the tire's nail self-repair function and effectively reducing tire noise; existing similar products have the following defects in the key glue step:

[0003] Due to the high-speed rotation of the glue spraying machine, the tire runs unstably on the machine, and the glue is unevenly applied, thick in some places and thin in others, which seriously affects the driving stability of the tire.

[0004] Some equipment heats the colloid and then hits it vertically on the inside of the tire, and uses centrifugal force to throw the hot glue to both sides of the extension. This process will cause the middle to be too thick and the two sides to be too thin, and the adhesion between the edge of the adhesive layer and the inner wall of the tire cannot meet the requirements, and it cannot achieve long-term stability for 3-5 years of use.

It is combined with the self-developed colloid based on polymer rubber to achieve the "forked" glue spraying of the glue gun head on the inner side of the tire, and then the high-speed rotating centrifugal force is used to merge the glue on both sides in the middle. This technology can ensure the thickness of the middle glue layer while ensuring that the thickness of the edges on both sides can reach 4-5mm. Moreover, because the glue is sprayed on both sides and then rotated at a high speed, the glue on both sides will continue to extend, effectively expanding the protection area of ​​the tire.
