[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0022] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are all based on the attached Figure 1 , and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present application.

[0023] As Figure 1-2 shown, a convection box structure of a glass heating furnace includes a heating furnace 1 having a conveyor 2 and heating wires 16, and further includes a first convection box 3, a second convection box 4, an air flow hood 8, a centrifugal fan 9 and a motor 10. The first convection box 3 and the second convection box 4 are arranged side by side as a group. Multiple groups of the first convection box 3 and the second convection box 4 are provided in the heating furnace 1. Both the first convection box 3 and the second convection box 4 are of a hollow structure, and air outlet holes 7 are densely formed in the bottoms of both the first convection box 3 and the second convection box 4. A first air inlet pipe 5 is communicatively provided at the front of the first convection box 3, and a second air inlet pipe 6 is communicatively provided at the rear of the second convection box 4. There are multiple air flow hoods 8, and each air flow hood 8 is communicatively connected to multiple first air inlet pipes 5 or multiple second air inlet pipes 6. The number of centrifugal fans 9 is equal to the number of air flow hoods 8, and the centrifugal fans 9 are located inside the heating furnace 1. The centrifugal fans 9 are communicatively connected to the air flow hoods 8 one by one for sending hot air. The motor 10 is fixedly installed on the outer wall of the heating furnace 1, and the output shaft of the motor 10 is fixedly connected to the impeller of the centrifugal fan 9 for driving the impeller to rotate.

[0024] Specifically, hot air can flow inside the hollow structures of the first convection box 3 and the second convection box 4, so that the hot air can be ejected from all the air outlet holes 7 onto the glass. The motor 10 drives the impeller of the centrifugal fan 9 to rotate, so that the centrifugal fan 9 extracts the hot air inside the heating furnace 1 and sends it into the air flow hood 8, and the air flow hood 8 then sends the hot air into multiple first air inlet pipes 5 or second air inlet pipes 6.

[0025] Furthermore, it further includes a support plate 11 and a suspension rod 14. The support plate 11 is fixedly connected to the first convection box 3 and the second convection box 4 of each group for supporting the first convection box 3 and the second convection box 4. Each support plate 11 is fixedly connected to two suspension rods 14. The first ends of the suspension rods 14 are connected to both ends of the support plate 11 one by one, and the second ends of the suspension rods 14 are fixedly connected to the top of the heating furnace 1.

[0026] Specifically, multiple support plates 11 are connected to each group of the first convection box 3 and the second convection box 4, so that the support plates 11 and the suspension rods 14 cooperate to stably support the first convection box 3 and the second convection box 4. The support plate 11 supports the lower parts of the first convection box 3 and the second convection box 4 to prevent the first convection box 3 and the second convection box 4 from falling. At the same time, the suspension rod 14 hoists the support plate 11 to avoid affecting the passage of the glass below.

[0027] Further, two mounting grooves 12 for receiving the first convection box 3 and the second convection box 4 respectively are provided on the pallet 11, and there is a gap between the two mounting grooves 12.

[0028] Specifically, there is a raised portion between the two mounting grooves 12 on the pallet 11, so that there is a gap between the first convection box 3 and the second convection box 4 in the mounting groove 12, enabling the hot air in the heating furnace 1 to circulate.

[0029] Further, through holes 13 for the suspension rods 14 to pass through are formed at both ends of the pallet 11, and mounting holes 15 for the passing of fasteners are formed through one end of the suspension rods 14 passing through the through holes 13.

[0030] Specifically, during installation, the suspension rods 14 pass through the through holes 13 and then connect fasteners to fasten the pallet 11, preventing the pallet 11 from falling off, and further supporting the first convection box 3 and the second convection box 4.

[0031] Further, the length dimensions of the first convection box 3 and the second convection box 4 are greater than the width of the conveyor 2, so that the hot air ejected from the air outlet holes 7 on the first convection box 3 and the second convection box 4 can cover the entire piece of glass.

[0032] Further, the air outlet holes 7 are strip-shaped holes to increase the air output, and at the same time form a hot air flow with a length, which then diffuses when blown onto the glass, further uniformly heating the glass.

[0033] In the above structure, the glass to be heated is placed on the conveyor 2 and conveyed into the heating furnace 1. The high temperature generated by the first convection box 3 increases the temperature in the heating furnace 1 to heat the glass. At the same time, the motor 10 is started to drive the centrifugal fan 9 to operate. The centrifugal fan 9 extracts the high-temperature air flow in the heating furnace 1 and sends it into the air flow cover 8, and then enters the first convection box 3 and the second convection box 4 respectively from the first air inlet pipe 5 and the second air inlet pipe 6. After flowing through the first convection box 3 and the second convection box 4, it is uniformly ejected from the air outlet holes 7 onto the glass to uniformly heat the glass and avoid the phenomenon of uneven heating.

[0034] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
