Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figs. 1-3 As shown, the present invention proposes an automatic continuous glass tempering furnace, which includes a conveyor frame 1 and several conveyor rollers 2 rotatably connected to the inner side of the conveyor frame 1. The tempering furnace body 5 is installed on the conveyor frame 1, and a glass tempering preheating component 4 is provided on the conveyor frame 1.

[0027] In this invention, the preheating component 4, located on the conveyor frame 1 and in front of the tempering furnace body 5, can preheat the glass during the conveying process, so that the glass, which already has heat, will have a shorter tempering time after being conveyed into the tempering furnace body 5, thereby improving processing efficiency.

[0028] It should be noted that the conveyor frame 1 is provided with a drive component 3 for driving the conveyor roller 2. The drive component 3 includes a conveyor motor installed on the back of the conveyor frame 1, and the output shaft of the conveyor motor is fixedly connected to one end of the leftmost conveyor roller 2. A sprocket is fixedly connected to one end of the conveyor roller 2 near the inner wall of the conveyor frame 1, and a chain is engaged on the sprocket.

[0029] In an optional embodiment, the preheating component 4 includes a top ventilation chamber 41 slidably connected to the conveyor frame 1, a bottom ventilation chamber 47 slidably connected to the inner bottom wall of the conveyor frame 1, ventilation pipes 49 connected to one side of both the top ventilation chamber 41 and the bottom ventilation chamber 47, and the bottom ventilation pipe 49 penetrating the conveyor frame 1, and an installation chamber 410 located on one side of the conveyor frame 1 connected between the two ventilation pipes 49, a plurality of heating pipes 411 installed on the inner side of the installation chamber 410, an air inlet pipe 412 connected to one side of the installation chamber 410, a servo motor 43 fixedly installed on the tempering furnace body 5, a connecting plate 45 fixedly connected to the top ventilation chamber 41, a threaded rod 44 with one end penetrating the connecting plate 45 fixedly connected to the output shaft of the servo motor 43, and a plurality of air outlets 46 opened on the side of the top ventilation chamber 41 and the bottom ventilation chamber 47 near the conveyor roller 2.

[0030] In this embodiment, the glass conveyed into the tempering furnace body 5 by the reciprocating top ventilation chamber 41 and bottom ventilation chamber 47 can be preheated synchronously from top to bottom in advance by the conveying roller 2, so that the glass itself has a certain temperature before tempering, thereby shortening the tempering time required after the glass enters the tempering furnace and improving the glass processing efficiency.

[0031] It should be noted that several air outlets 46 are distributed in a matrix on the top ventilation chamber 41 and the bottom ventilation chamber 47, so that the hot air delivered to the top ventilation chamber 41 and the bottom ventilation chamber 47 can be evenly blown onto the glass being transported. A valve is installed at the end of the ventilation pipe 49 away from the installation chamber 410. The valve on the ventilation pipe 49 is used to adjust the air supply of the ventilation pipe 49, thereby adjusting the ventilation volume in the top ventilation chamber 41 and the bottom ventilation chamber 47, so as to adjust the heating temperature of the upper and lower surfaces of the glass.

[0032] The air inlet pipe 412 is a flexible hose, and the air inlet end of the air inlet pipe 412 can be connected to a conventional fan to supply air into the installation chamber 410. The connecting plate 45 has a threaded hole, and the threaded hole and the thread on the outside of the threaded rod 44 cooperate with each other, so that the threaded rod 44 driven by the servo motor 43 can drive the top ventilation chamber 41 to slide back and forth on the conveyor frame 1, thereby driving the bottom ventilation chamber 47 to slide along with it.

[0033] In addition, a groove is provided on the upper surface of the conveyor frame 1, and a slider is fixedly connected to the lower end of the top ventilation chamber 41, with one end extending to the inside of the groove. The slider is slidably connected to the groove. The stability of the top ventilation chamber 41 when sliding on the conveyor frame 1 is improved by limiting the sliding of the groove and the slider.

[0034] In an optional embodiment, several shielding curtains 6 are installed on the side of the top ventilation chamber 41 away from the tempering furnace body 5 and at the discharge end of the tempering furnace body 5. A connecting sleeve 42 is fixedly connected between the top ventilation chamber 41 and the tempering furnace body 5. A through hole 7 is opened on the back of the conveyor frame 1 for the bottom ventilation pipe 49 to move. A sealing sleeve 48 is fixedly connected to the inside of the through hole 7, with one end fixedly connected to the bottom ventilation pipe 49.

[0035] In this embodiment, the heat loss during the glass heating process can be reduced by the connecting sleeve 42 installed between the top ventilation chamber 41 and the tempering furnace body 5, the shielding curtain 6 on one side of the top ventilation chamber 41 and the discharge end of the tempering furnace body 5, and the sealing sleeve 48 in the perforation 7, thereby improving the heating effect during glass tempering.

[0036] It should be noted that both the sealing sleeve 48 and the connecting sleeve 42 are rubber sleeves. The sealing sleeve 48 is conical and the connecting sleeve 42 is concave. When the sealing sleeve 48 is connected to the top ventilation pipe 49, it can block the perforation 7 and also expand and contract with the bottom ventilation pipe 49. The connecting sleeve 42 can block the gap between the top ventilation chamber 41 and the tempering furnace body 5 and can also expand and contract with the movement of the top ventilation chamber 41.

[0037] The working principle in the above embodiments is as follows:

[0038] The glass to be tempered is placed on the conveyor roller 2 for conveying, and is ventilated into the installation chamber 410 through the air inlet pipe 412. After being heated by the heating pipe 411, the hot air is conveyed into the top ventilation chamber 41 and the bottom ventilation chamber 47 through the ventilation pipes 49 on the upper and lower sides respectively, and discharged through several air outlets 46 on the top ventilation chamber 41 and the bottom ventilation chamber 47. The hot air can be blown evenly on the glass conveyed between the top ventilation chamber 41 and the bottom ventilation chamber 47 to preheat the glass. After the heated glass is conveyed into the tempering furnace body 5, the time required for glass tempering can be shortened.

[0039] The connecting sleeve 42 located between the top ventilation chamber 41 and the tempering furnace body 5 can block the gap without interfering with the sliding of the top ventilation chamber 41. The sealing sleeve 48 located in the perforation 7 can block the perforation 7 without interfering with the movement of the top ventilation pipe 49. Together with the shielding curtain 6 on one side of the top ventilation chamber 41 and the discharge end of the tempering furnace body 5, the heat loss during the glass heating process can be reduced, thereby improving the heating effect during glass tempering.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
