Wherein the toughening furnace 200 is positioned below, the preheating furnace 100 and the cooling furnace 300 are inverted, and are positioned above the left and right of the toughening furnace 200 and arranged in an inverted Chinese character 'pin'. In the production process, the glass to be treated is put into and taken out of the three furnaces by the mechanical arm controlled by a program, the glass to be treated is firstly put into the preheating furnace 100 positioned at the upper left, the mechanical arm takes the glass to be treated out of the preheating furnace 100 after preheating and puts the glass into the toughening furnace 200 at the lower part for ion replacement treatment, then the mechanical arm puts the next batch of glass to be treated into the preheating furnace 100, and the glass in the toughening furnace 200 is taken out of the cooling furnace 300 after toughening.

The applicant finds that the batch production of chemically tempered glass by using the glass chemical tempering equipment in the prior art has at least the following disadvantages:

1) the frequent opening and closing of the furnace door of the toughening furnace 200 is required, so that the probability of equipment failure and the probability of external foreign matters entering the toughening furnace 200 are increased;

2) the toughening furnace 200 is usually a large-capacity cubic mechanism, and in order to ensure uniform heating of the molten salt in the toughening furnace 200, heating mechanisms need to be arranged on the bottom surface and four side surfaces of the toughening furnace 200, so that the toughening furnace 200 has a complex structure;

3) the tempering furnace 200 is generally deep, which results in a complicated procedure for replacing the molten salt, and the tempering furnace 200 is difficult to clean and takes a long time.

With reference to fig. 6, the front side plate 51 and the rear side plate 52 are respectively provided with a hook hole 55 that is through from front to back, as can be seen from fig. 5, the connecting rod 72 is provided with a pair of hooks 76 that are opposite from front to back, and when the first rack 5 needs to be mounted on the connecting rod 72, the hook holes on the front side plate 51 and the rear side plate 52 only need to be respectively hooked on the two hooks 76 on the connecting rod 72. Therefore, the first material frame 5 can be detachably connected to the material conveying device 7, so that the first material frame 5 is driven by the material conveying device 7 to penetrate out of the material outlet 1131, and then is quickly detached from the material conveying device 7.

As can be seen from the above description, when the integrated glass tempering apparatus provided in this embodiment is used to produce tempered glass, firstly, a proper amount of molten salt needs to be contained in the tempering chamber 112, then, the glass to be strengthened is inserted into the first rack 5, and then the first rack 5 into which the glass to be strengthened is inserted is hung on the connecting rod 72 of the material conveying device 7 only at the left side of the material outlet 1131, when the stepping motor of the material conveying device 7 operates, the conveyor chain can drive the first rack 5 carrying the glass to be strengthened to enter the furnace chamber 11 from the feed port 1111, and passes through the preheating chamber 111, the strengthening chamber 112, and the cooling chamber 113 in sequence, and then passes out of the discharge port 1131, as will be understood by those skilled in the art, the residence time of the glass to be strengthened in the preheating chamber 111, the strengthening chamber 112 and the cooling chamber 113 can be adjusted by controlling the start and stop of the stepping motor. In this way, the glass to be strengthened can be subjected to preheating, ion exchange, and cooling processes in the preheating chamber 111, the strengthening chamber 112, and the cooling chamber 113, respectively. When the first rack 5 carrying the glass to be strengthened penetrates out of the discharge hole 1131, the first rack 5 can be directly taken down from the connecting rod 72. The parts needing to move in the whole process are only the material conveying device 7, so that the automatic control is facilitated, the equipment failure rate is reduced, and the furnace door 2 is not required to be opened, so that the glass strengthening effect is prevented from being influenced by the fact that external foreign matters fall into the strengthening chamber 112.

Further, the integrated glass tempering apparatus further includes a first heat-insulating door 81 and a second heat-insulating door 82 which are parallel to and spaced apart from each other.

Similarly, a second frame 821 is further disposed on the upper side of the first cover 21, a second servo motor 822 is disposed on the second frame 821, and the second servo motor 822 and the second heat insulation door 82 are connected by a second lead screw 823 extending vertically, so that the second servo motor 822 can drive the second heat insulation door 82 to move up and down. In the process of producing tempered glass by using the integrated glass tempering device provided by this embodiment, after the first rack 5 loaded with glass to be tempered enters the preheating chamber 111, the first heat-insulating door 81 and the second heat-insulating door 82 can be moved down to the closed position, so that a relatively closed space can be formed between the first heat-insulating door 81 and the second heat-insulating door 82, and thus the glass to be tempered can be efficiently preheated in the space between the first heat-insulating door 81 and the second heat-insulating door 82.

Further, the second cover 22 is rotatably connected with the furnace body 1. After the integrated glass tempering device is used for a period of time, the second cover body 22 can be opened, so that the molten salt in the strengthening chamber 112 can be replaced.

With reference to fig. 8, a third frame 851 is installed on the upper side of the third cover 23, a third servo motor 852 is installed on the third frame 851, the tops of the third thermal insulation door 83 and the fourth thermal insulation door 84 are connected through a connecting plate 85, and a third lead screw connection 853 extending vertically is connected between the third servo motor 852 and the connecting plate 85, so that the third servo motor 852 can drive the connecting plate 85 to move up and down, and the connecting plate 85 can drive the third thermal insulation door 83 and the fourth thermal insulation door 84 to move up and down simultaneously when moving up and down. In the process of producing tempered glass by using the integrated glass tempering device provided by this embodiment, after the first rack 5 loaded with tempered glass enters the cooling chamber 113, the third heat-insulating door 83 and the fourth heat-insulating door 84 are moved down to the closed positions, so that the tempering chamber 112 and the cooling chamber 113 can be effectively blocked, heat in the tempering chamber 112 is prevented from being transferred to the cooling chamber 113, and the tempered glass is rapidly cooled in the cooling chamber 113.

Further, an inner container is disposed in the strengthening chamber 112, and an upper side of the inner container is open for containing molten salt. Therefore, when the molten salt is replaced, the old inner container can be directly taken out integrally and then replaced by a new inner container, and the molten salt replacement efficiency is greatly improved.
