Embodiment 1

[0037] The invention discloses a stress annealing method for a glass bottle, which specifically comprises the following steps:

[0038] (1) Forming and conveying: the bottle making machine 1 produces glass bottles through a thermoforming process, so that the glass bottles are in a high temperature state, and the bottle making machine places the glass bottles on the conveyor belt 3;

[0039] (2) Uniform heat: transfer to the heater 4 through the conveyor belt 3, and the heater 4 carries out uniform heat treatment to the glass bottle through a high-temperature flame;

[0040] (3) Annealing: the glass bottles are transported to the annealing furnace 2 by the conveyor belt 3, heated at a high temperature in the furnace through the heating chamber 21, annealed in the furnace through the heat preservation chamber 22, and finally cooled in the cooling chamber 23.

[0041] Specifically, in the above step (2), the heating temperature of the heater 4 is T1, preferably T1 is 450° C., so ...

Embodiment 2

[0050] The difference between this embodiment and the first embodiment lies in that the number and distribution of the heaters are different.

[0051] Such as image 3 As shown, in the present embodiment, there are four heaters 4, and the heaters 4 are respectively arranged on both sides of the conveyor belt 3 and arranged symmetrically. In order to gather the high-temperature flames sprayed from the flame nozzles in one place. Other structures and beneficial effects not described are the same as those in Embodiment 1.

[0052] The advantage of this setting is that the warmer conducts uniform heat treatment on the glass bottle from four angles, which can avoid uneven heating and improve the yield rate.

Abstract

The invention discloses a glass bottle stress annealing method. A bottle maker completes forming of glass bottles and conveys the glass bottles onto a conveying belt; the conveying belt conveys the glass bottles to a heating element; the heating element uniformly heat the bottle body of every glass bottle; the conveying belt conveys the glass bottles to an annealing furnace, and the glass bottles are processed through heating in a heating chamber, annealing in a heat insulating chamber and furnace cooling in a cooling chamber to complete the entire annealing process. The glass bottle stress annealing system comprises the bottle maker, the annealing furnace, the conveying belt sequentially penetrating through the bottle maker and the annealing furnace, a motor at the tail end of the conveying belt, and the heating element, wherein the heating element is arranged on the conveying belt and between the bottle maker and the annealing furnace; the annealing furnace is provided with the heating chamber for heating the glass bottles, the heat insulating chamber for annealing treatment, and the cooling chamber for furnace cooling. The glass bottle stress annealing method has the advantages of being high in yield and low in energy consumption.
