Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering, in particular to a tempering furnace with a special connecting roller structure. Background Art

[0002] The tempering of ultra-thin glass requires that the heating furnace section and the high-pressure cold quenching section of the glass tempering unit drive rollers be in the same plane, otherwise the surface quality will be affected when the glass is transferred from the heating furnace to the high-pressure cold extraction section in a softened state; however, in conventional glass tempering units, the heating furnace section and the high-pressure cold extraction section are respectively provided with roller support frames, and the flatness of the rollers of the heating furnace section and the high-pressure cold quenching section can be guaranteed. The flatness of the rollers of the heating furnace and the high-pressure cold quenching section can also be guaranteed in the cold state. However, in the high temperature state, due to the different expansion amounts, the flatness of the rollers of the heating furnace and the high-pressure cold quenching section is difficult to guarantee, which greatly affects the surface quality of the glass. Therefore, when the glass is in a softened state, it is extremely important to ensure the flatness of the rollers of the heating furnace and the high-pressure cold quenching section.

[0006] Furthermore, the support frame plate of the roller conveyor in front of at least the second set of air knives in the high-pressure cold quenching section is connected to the support frame plate of the roller conveyor of the heating furnace.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1As shown, it is the conventional structure of the connection between the heating furnace section and the high-pressure cold quenching section of the glass tempering unit in the prior art. The heating furnace section is composed of a heating furnace frame 1, a heating furnace roller support frame plate 2, a transmission round belt 3, a heating furnace transmission shaft 4, a heating furnace active pulley 5, a heating furnace passive pulley 6, a ceramic roller 7, etc. The ceramic roller 7 is supported by the heating furnace roller support frame plate 2, and the heating furnace transmission shaft 4 and the ceramic roller 7 are driven by the heating furnace active pulley 5, the heating furnace passive pulley 6 and the transmission round belt 3. The high-pressure cold quenching section is composed of a high-pressure cold quenching area frame 8, a high-pressure cold quenching area roller support frame plate 9, a transmission active belt 10, a high-pressure cold quenching area transmission shaft 11, a high-pressure cold quenching area active pulley 12, a high-pressure cold quenching area passive pulley 13, a roller 14, an upper air grid group 15, a lower air grid group 16, etc.; the roller 14 in the high-pressure cold extraction area is connected to the high-pressure cold extraction area through the high-pressure cold extraction area. The roller support frame plate 9 is used for support, and the transmission shaft 11 of the high-pressure cold extraction zone and the roller 14 are transmitted through the high-pressure cold extraction zone active pulley 12, the high-pressure cold extraction zone passive pulley 13 and the transmission flexible belt 10. The upper wind grid group 15 and the lower wind grid group 16 are respectively arranged on the upper and lower sides of the roller 14 of the high-pressure cold extraction section. The heating furnace section and the high-pressure cold quenching section have their own roller support frame plates, and the roller support plates are used to ensure that the busbars on the connected rollers are in the same plane. The flatness of the rollers of the heating furnace section and the high-pressure cold extraction section can be guaranteed, and the flatness of the rollers of the heating furnace and the high-pressure cold quenching section can also be guaranteed in the cold state. However, in the high-temperature state, due to the different expansion amounts of the heating furnace section and the high-pressure cold extraction section, the flatness of the rollers of the heating furnace and the high-pressure cold quenching section is difficult to ensure. The glass enters the high-pressure cold quenching section in a softened state, which affects the surface quality of the glass.

[0015] As attached Figure 2As shown, it is the structure of the connection between the heating furnace section and the high-pressure cold quenching section of the glass tempering unit of the utility model, which is similar to the prior art. The heating furnace part is composed of a heating furnace frame 1, a heating furnace roller support frame plate 2, a transmission round belt 3, a heating furnace transmission shaft 4, a heating furnace active pulley 5, a heating furnace passive pulley 6, a ceramic roller 7, etc. The ceramic roller 7 is supported by the heating furnace roller support frame plate 2, and the heating furnace transmission shaft 4 and the ceramic roller 7 are driven by the heating furnace active pulley 5, the heating furnace passive pulley 6 and the transmission round belt 3. The high-pressure cold quenching section is composed of a high-pressure cold quenching area frame 8, a high-pressure cold quenching area roller support frame plate 9, a transmission active belt 10, a high-pressure cold quenching area transmission shaft 11, a high-pressure cold quenching area active pulley 12, a high-pressure cold quenching area passive pulley 13, a roller 14, an upper air grid group 15, and a lower air grid group 16, etc., the roller 14 of the high-pressure cold extraction section is supported by the high-pressure cold extraction zone roller support frame plate 9, the high-pressure cold extraction zone drive shaft 11 and the roller 14 are transmitted through the high-pressure cold extraction zone active pulley 12, the high-pressure cold extraction zone passive pulley 13 and the transmission active belt 10, the upper wind grid group 15 and the lower wind grid group 16 are respectively arranged on the upper and lower sides of the high-pressure cold extraction zone roller 14, the wind knife of the upper wind grid group 15 and the wind knife of the lower wind grid group 16 are correspondingly set, the difference is that, in the utility model, the support frame plate of the roller 14 in front of the high-pressure cold quenching section wind knife is connected with the heating furnace roller support frame plate 2, so as to ensure that the roller 14 in front of the high-pressure cold extraction zone wind knife is consistent with the height change of the ceramic roller 7 of the heating furnace, so that the arrangement can ensure that when the glass is softened, the busbar on the roller contacting the glass is on the same surface. Preferably, the support frame plate of the roller 14 in front of at least the second group of wind knives in the high-pressure quenching section is connected to the support frame plate 2 of the heating furnace roller, so that the flatness adjustment of this part of the roller (i.e., at least the second group of wind knives in the high-pressure quenching section) follows the heating furnace ceramic roller 7, and the transmission of the high-pressure quenching zone roller 14 does not change; when the support frame plate of the roller 14 in front of at least the second group of wind knives in the high-pressure quenching section is connected to the support frame plate 2 of the heating furnace roller, the transmission of this part of the roller 14 follows the heating furnace section or the high-pressure quenching section.

[0016] The tempered glass furnace with a special connection structure of the utility model improves the structure of the connection between the heating furnace section and the high-pressure cold extraction section. When the equipment is operating normally, even if the deformation of the heating furnace in the high-temperature state is different from the deformation of the high-pressure cold extraction zone, because all the rollers in front of the second group of wind knives in the high-pressure cold extraction section are in the same plane, the flatness of the glass in the softened state can be guaranteed. After passing through the second group of wind knives, the surface of the glass has been hardened, and the surface quality is no longer affected by the flatness of the busbar on the roller, thereby greatly improving the surface quality of the tempered glass.
