[0002] Thermochromic coating glass can automatically change color according to the change of ambient temperature and adjust the transmittance, so as to effectively control the indoor and outdoor heat exchange and achieve good daylighting adjustment. Thermally insulating coating glass focuses on heat insulation. Through special coating and response mechanisms, it blocks heat transfer and plays a role in energy conservation and consumption reduction.

[0003] In the production process of coating glass, the high-temperature annealing furnace is one of the key equipment. The performance of its heating mechanism plays a crucial role in whether the coating glass can form thermochromic and thermally insulating characteristics well. However, the existing heating mechanisms of high-temperature annealing furnaces often have problems such as uneven heating, difficulty in precisely controlling temperature changes to adapt to the reaction requirements of thermochromic and heat-insulating related coating materials, low heat utilization rate, etc. In addition, the sizes of different models of glass are also different, and it is inconvenient for workers to fix glasses of different sizes.

The protective net 104 plays a role of isolation and protection.

[0040] The specific usage method and function of this embodiment:

[0041] In this application, the door panel 101 rotatably connected to the front end face of the annealing box 1 is convenient for opening and closing, facilitating the operator to put the workpiece to be annealed into or take it out of the annealing box 1. Connecting seats 2 are fixedly installed on the left and right outer end faces of the annealing box 1, and the heating wires 201 fixedly installed on the connecting seats 2 are located inside the annealing box 1. The heating wires 201 can generate heat after being energized, thereby raising the temperature environment inside the annealing box 1. At the same time, two transverse chutes 103 are respectively opened on the bottom surface and the top plate surface of the annealing box 1. Fastening blocks 5 are clamped inside the transverse chutes 103, and the fastening screws 501 on the upper end faces of the fastening blocks 5 are clamped in the through holes 401 on the surface of the placement plate 4. After the worker tightens the nuts on the surface of the fastening screws 501, the placement plate 4 can be fixed, facilitating the clamping of both ends of the glass in the card slots on the surface of the card seat 402. A control unit 3 is installed on the upper end face of the connecting seat 2, and the temperature sensor 301 installed on the front end face of the control unit 3 is located inside the annealing box 1. The temperature sensor 301 can continuously sense the temperature inside the annealing box 1 and feed the temperature signal back to the control unit 3. The control unit 3 then adjusts the energized state of the heating wire 201 according to the preset annealing temperature parameters. When the temperature detected by the temperature sensor 301 is lower than the preset annealing temperature value, the control unit 3 will keep the heating wire 201 continuously energized or increase its power to promote the temperature rise; when the temperature reaches or exceeds the preset value, the control unit 3 will correspondingly adjust the power of the heating wire 201 or even cut off the power supply to keep the temperature within a suitable annealing temperature range, thereby precisely controlling the temperature environment during annealing, enabling the coated glass to be uniformly heated as a whole and avoiding the occurrence of local overheating or insufficient heating. This is very crucial for ensuring the consistency of the subsequent performance of the coated glass. Especially for coated glass with special functional requirements such as thermochromism and thermal insulation, uniform heating helps the coating material to uniformly undergo corresponding physical and chemical changes. In addition, four connecting seats 2 are respectively installed on the outer end faces of the left and right side plates of the annealing box 1, and the control unit 3 is installed on the upper end faces of all the connecting seats 2. Therefore, there are eight temperature sensors 301 inside the annealing box 1 to detect the temperature, which can avoid the situation of uneven temperature inside the annealing box 1. The placement plate 4 is provided with two upper and lower groups, and card seats 402 are uniformly installed on its outer end face. The card slots opened on the surface of the card seats 402 can be used to place the glass workpieces to be annealed, and the card slots can play a certain positioning role for the workpieces to prevent them from moving randomly during annealing. Moreover, ventilation holes 4021 are uniformly opened on both ends of the surface of the card seat 402. On the one hand, it helps the hot air inside the annealing box 1 to fully flow around the workpiece, making the workpiece heated more uniformly;On the other hand, in some cases where annealing requires a specific gas atmosphere, it is also convenient for the corresponding gas to circulate around the workpiece to ensure the annealing effect. At the same time, the fastening screw 501 at the lower position is sleeved with a limiting cylinder 6. The limiting cylinder 6 is located below the placement plate 4 and can lift the position of the lower placement plate 4. By replacing the limiting cylinders 6 of different specifications, the distance between the upper and lower placement plates 4 can be adjusted, which is convenient for fixing and limiting glass workpieces of different heights. Two protective nets 104 are symmetrically installed inside the annealing box 1. The heating wire 201 is located between the protective net 104 and the side plate of the annealing box 1. The protective net 104 plays a role of isolation and protection. It can prevent operators from accidentally touching the heating wire 201 and getting an electric shock when opening the door panel 101 to check or operate. At the same time, it can also prevent the workpiece from accidentally colliding with the heating wire 201 during the placement and removal process, protecting the heating wire 201 and extending its service life, ensuring that the heating system of the entire annealing box 1 can operate stably and reliably, and guaranteeing the normal development of the annealing work.
