Detailed Description
In order to make the technical purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are further described below with reference to the accompanying drawings and specific embodiments.
The invention relates to a specific embodiment of a bottle bottom firing device for a tubular glass bottle, wherein a bottle making machine mainly comprises an A part and a B part, wherein the A part is 12 stations, the B part is 6 stations, the total number of the stations is 18, the A part is mainly used for making a bottle mouth part, and the processing of the bottle mouth is completed through hot processing and secondary forming of different machine stations; and the part B is mainly used for finishing the manufacturing and forming of the bottle bottom, and finally forming a complete glass bottle product to enter an annealing furnace. 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 includes a frame 1, a central shaft is disposed on the frame 1, a firing platform 2 is fixed on the central shaft, a plurality of firing stations 3 are disposed on an upper end surface of the firing platform 2 at intervals around a circumferential direction of the firing platform, each firing station 3 is fixed with a positioning structure for positioning and matching with a glass bottle so as to extend an axis of the glass bottle up and down, the positioning structure has a positioning shaft, the positioning structure rotates around the positioning shaft after the glass bottle is disposed on the positioning structure, a lamp cap is disposed on the frame 1 corresponding to each firing station 3, the lamp cap is used for blowing fire to the glass bottle of each station, for one firing station 3, in a process of moving along with the firing platform 2, the glass bottle passes through a fire blowing region of each lamp cap, and is left for a set time in each fire blowing region, the positioning shaft in the series of firing processes continuously drives the glass bottle to rotate, and after all firing stations are finished, the glass bottle can be formed from the glass tube.
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 the matrix, so that the firepower can be reduced to 1/3 of the original firepower, 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 of the bottle bottom, so that the bottle bottom is prevented from contacting with 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) cutting by bottom; 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 annealing; (5) naturally cooling; and (6) cooling and unloading the bottle. Wherein, the steps (1) to (4) involve the flame spraying of the lamp holder to the glass tube. Unlike the prior art, in which each flaming angle extends horizontally, in this embodiment, in step (2), the flame power is reduced, the flame is fired toward the bottom of the glass bottle along the top-to-bottom inclination, and is blown toward the center of the bottom of the bottle from the shoulder formed by connecting the bottle body and the bottom of the bottle, and is fired from the shoulder to the center of the bottom of the bottle to form an inwardly concave arc surface, and the shoulder also forms a rounded structure 10, which is different from a right-angle structure, thereby avoiding the problem of too concentrated local stress at the shoulder of the glass bottle, and forming an inwardly concave arc surface from the inner edge of the shoulder to the center of the bottom of the 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.
