Tube-type glass bottle bottom firing process and bottle bottom firing device thereof

The invention relates to a tube-type glass bottle bottom firing process and a bottle bottom firing device thereof. The tube-type glass bottle bottom firing process comprises the following steps: (1) performing bottom cutting; (2) preparing a bottom; (3) molding and polishing the bottle bottom; (4) heat preservation and annealing; (5) naturally cooling; and (6) cooling and unloading bottles. In thestep (2), the fire power of flame is reduced, the flame obliquely faces a glass bottle from top to bottom to fire the bottle bottom and blows to the center of the bottle bottom from a shoulder peak formed by connecting the bottle body and the bottle bottom, so that a fillet structure is formed at the shoulder peak connecting the bottle body and the bottle bottom, and a concave arc surface is formed from the inner edge of the shoulder peak to the center of the bottle bottom. Therefore, contact between the bottle bottom and the surface of an object is avoided, and damage caused by collision ofthe contact surface is eff
