In the application, the part B is mainly improved, namely, the part B equipment forms a bottle bottom burning device.
As shown in fig. 1-2, consistent with the prior art, the bottle bottom firing device comprises a frame 1, a central shaft is arranged on the frame 1, a firing platform 2 is fixed on the central shaft, a plurality of firing stations 3 are arranged on the upper end surface of the firing platform 2 at intervals around the circumference of the firing platform, a positioning structure for positioning and matching with glass bottles to enable the axes of the glass bottles to extend up and down is fixed on each firing station 3, the positioning structure is provided with a positioning shaft, after the glass bottles are arranged on the positioning structure, the positioning structure rotates around the positioning shaft, meanwhile, lamp caps are arranged on the frame 1 corresponding to each firing station 3 and used for blowing fire to the glass bottles of each station, for one firing station 3, in the process of moving along with the firing platform 2, the glass bottles pass through the fire blowing regions of each lamp cap and stay for a set time in each fire blowing region, in the series of firing processes, the positioning shaft continuously drives the glass bottles to rotate, and after all the glass bottles are finished, the glass bottles can be formed from the glass tubes.
The burners of each firing station 3 are defined as a cutting burner 4, a bottoming burner 5, a polishing burner 6 and a heat-retaining burner 7 in that order. The internal constructional structure of each lamp cap is substantially similar and substantially indistinguishable from the prior art and therefore will not be described in detail.
In the present embodiment, the base unit 5 includes a connection portion 52 for fixing to the frame 1, and a fire blowing portion 51 connected to an upper side of the connection portion 52, and the fire blowing portion 51 communicates with the air supply pipe and sprays flames. After the glass tube is cut, the glass tube enters the spraying area of the bottom-making lamp holder 5, at the moment, the bottom-making lamp holder 5 blows fire towards the glass bottle, the upper end of the glass tube is burnt and melted, and the bottle bottom is formed gradually. In the present embodiment, the fire hole of the fire blowing part 51 is inclined from top to bottom and extends toward the positioning structure so that the fire blows out from the shoulder formed by the connection of the body and the bottom of the glass bottle to the center of the bottom of the glass bottle, thereby forming the rounded structure 10 at the shoulder.
Furthermore, after the flame injection angle is adjusted, in order to avoid the phenomenon that the bottom of the bottle is fused due to overlarge flame, the flame injection port of the bottom lamp holder 5 is reduced from the existing nine holes and is changed into three holes, and the holes are arranged along a matrix, so that the firepower can be reduced to 1/3 originally, and after the bottle is formed, a certain radian exists from the inner edge of the shoulder peak position where the bottle body is connected with the bottom of the bottle to the center of the bottom of the bottle.
Further, through a large amount of experiments and data summarization, the inclined angle of the flame-throwing hole is optimally 35 degrees, and of course, the inclined angle can be designed to be 30 degrees or 40 degrees, and can be arbitrarily selected between 30 degrees and 40 degrees.
The flame spraying angle is improved on the prior art, and the problem of over-concentration of local stress at the shoulder peak of the glass bottle is mainly solved; meanwhile, as shown in fig. 3, the design of the concave cambered surface 8 improves the bearing capacity of the bottle in the process of filling the gland; the thickness of the bottle bottom is more reasonable, and particularly, a small salient point 9 is formed at the center of the bottle bottom and is called as a sun bottom, so that the firmness of the bottle bottom is greatly improved; the concave radian of 0.5-0.8mm is formed from the center of the bottle bottom to the connecting shoulder peak of the bottle bottom, so that the bottle bottom is prevented from contacting the surface of an object, and the damage caused by the impact of a contact surface is effectively reduced.
Of course, in other embodiments, the inclination angle may be changed according to the actual diameter and height of the glass tube, and is not particularly limited.
In other embodiments, the burner of the base burner 5 can be designed as another number of porous structures.
The invention relates to a specific embodiment of a bottle bottom burning process for a tube-type glass bottle, which comprises the following steps; (1) bottom cutting; cutting the glass tube, and forming an opening at the upper end of the glass tube; (2) preparing a bottom; (3) forming and polishing the bottle bottom; (4) heat preservation and annealing; (5) naturally cooling; (6) and (5) cooling and unloading the bottle. Wherein, the steps (1) to (4) involve the flame spraying of the lamp holder to the glass tube. Different from the prior art in which each flaming angle horizontally extends, in this embodiment, in step (2), flame fire is reduced, flame is fired toward the bottom of the glass bottle along the upward and downward inclination, the flame is blown toward the center of the bottom of the glass bottle from the shoulder formed by connecting the bottle body and the bottom of the glass bottle, the shoulder is fired toward the center of the bottom of the glass bottle to form an inward-concave arc surface, and the shoulder also forms a fillet structure 10, which is different from a right-angle structure, so that the problem of too concentrated local stress at the shoulder of the glass bottle is avoided, and the inward-concave arc surface is formed from the inner edge of the shoulder to the center of the bottom of the glass bottle. The arrangement can form a cambered surface at the bottom of the bottle, and can form a protrusion formed by stacking at the center of the bottom of the bottle, commonly called as a sun bottom. The firmness of the bottle bottom is greatly improved; the concave radian of 0.5-0.8mm is formed from the center of the bottle bottom to the connecting shoulder peak of the bottle bottom, so that the bottle bottom is prevented from contacting the surface of an object, and the damage caused by the impact of a contact surface is effectively reduced.
Finally, it should be noted that: the above embodiments are merely illustrative and not restrictive of the technical solutions of the present invention, and any equivalent substitutions and modifications or partial substitutions made without departing from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
