Glue spraying device of tire inner cavity suitable for high-temperature-resistant rubber material

The invention discloses a glue spraying device of a tire inner cavity suitable for a high-temperature-resistant rubber material. The glue spraying device is a bubble atomizing nozzle, a liquid inlet is formed in the top end of a mixer, an adjusting sleeve sleeves the mixer, an outer wall sleeves the adjusting sleeve, and an inclined first air hole is formed in the mixer; and an inclined second airhole is formed in the side wall of the adjusting sleeve, the communication or the non-communication of the first air hole and the communication or the non-communication of the second air hole are determined by the relative position of the mixer and the adjusting sleeve; a first gas-liquid mixing chamber and a second gas-liquid mixing chamber are arranged inside the mixer, and the liquid inlet communicates with the first gas-liquid mixing chamber, and the lower end of the first gas-liquid mixing chamber communicates with the second gas-liquid mixing chamber; and a first air inlet is correspondingly formed in the posit
