[0036] According to one aspect of the present application, an embodiment of the present application provides an infrared heating module, please refer to Figures 1 to 6 The infrared heating module includes a lampshade 1, an infrared lamp tube 2 and a metal wire mesh 3. A accommodating space is formed inside the lampshade 1. An opening connected to the accommodating space is provided at the bottom of the lampshade 1. The infrared lamp tube 2 is provided in the accommodating space, and the metal wire mesh 3 is provided at the opening.

[0037] In the embodiment of the present application, the infrared heating module includes a lampshade 1, an infrared lamp tube 2 and a metal wire mesh 3. The bottom of the lampshade 1 is provided with an opening connected to the accommodating space. The infrared lamp tube 2 is arranged in the accommodating space, and the metal wire mesh 3 is arranged at the opening. The metal wire mesh 3 can not only ensure that most of the infrared radiation is transmitted, but also prevent fragments from splashing out when the infrared lamp tube 2 breaks, effectively ensuring the safety of production equipment and operators, reducing the risk of explosion of related components of the infrared heating module and the coating system, and improving the safety performance of the infrared heating module and the coating system.

[0038] In one embodiment, the lampshade 1 is made of stainless steel, which has high strength and can stably withstand the impact caused by the explosion of the internal infrared lamp tube 2; the wall surface of the accommodating space in the lampshade 1 is coated with a reflective coating or polished to improve the reflectivity of infrared light.

[0039] In one embodiment, please refer to Figures 1 to 4 The lampshade 1 is composed of a first shell 110 and a second shell 120. The bottom edge of the first shell 110 is provided with a first notch, and the bottom edge of the second shell 120 is provided with a second notch. The first notch and the second notch are combined to form an opening.

[0040] In this way, the lampshade 1 is composed of the first shell 110 and the second shell 120 , and the first shell 110 and the second shell 120 are easily assembled and disassembled, so that the infrared lamp 2 inside the lampshade 1 can be easily maintained and replaced.

[0041] In one embodiment, see Figure 3 Two metal meshes 3 are provided, and the two metal meshes 3 are fixed on the first notch and the second notch respectively. The metal mesh 3 and the first shell 110 or the second shell 120 are an integrated structure, and the structure is relatively stable.

[0042] In one embodiment, see Figure 4 An embedding block 111 is provided on the side of at least one end of the first shell 110 facing the second shell 120, and a first card slot 121 is provided on the second shell 120 corresponding to the embedding block 111. A second card slot 122 connected to the first card slot 121 is provided on the outer surface of the second shell 120, and a telescopic button 112 that can be pressed into the embedding block 111 is provided on the side of the embedding block 111 corresponding to the second card slot 122.

[0043] In this way, when the embedded block 111 is inserted into the first card slot 121, the telescopic button 112 pops out and enters the second card slot 122, realizing the locking between the first shell 110 and the second shell 120; when the first shell 110 and the second shell 120 need to be separated, press the telescopic button 112 in the second card slot 122 to retract the telescopic button 112, so that the embedded block 111 can easily exit the first card slot 121.

[0044] Furthermore, when the embedding block 111 is inserted into the first slot 121 , the side surface of the telescopic button 112 that first contacts the second shell 120 is an inclined surface, so that the telescopic button 112 can automatically retract after contacting the second shell 120 .

[0045] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 5 The infrared heating module also includes two ferrules 4 , which are respectively sleeved on both ends of the lampshade 1 . The ferrules 4 include a metal sleeve 410 and a ceramic sleeve 420 , and the ceramic sleeve 420 is embedded in the metal sleeve 410 .

[0046] By the above arrangement, the metal sleeve 410 can provide stable installation for the mounting plate 5 described below, and the friction between the ceramic sleeve 420 and the first shell 110 and the second shell 120 is large, reducing the possibility of the first shell 110 and the second shell 120 falling off.

[0047] In one embodiment, see Figure 3 A first avoidance hole 130 is provided at the end of the first shell 110 and / or the second shell 120, and a second avoidance hole 430 is provided at the ferrule 4 corresponding to the first avoidance hole 130. The first avoidance hole 130 and the second avoidance hole 430 are used for the wire 210 of the infrared lamp tube 2 to pass through.

[0048] In this embodiment, the ends of the first shell 110 and the second shell 120 are both provided with a first avoidance hole 130 , and the ferrule 4 is provided with two second avoidance holes 430 .

[0049] In one embodiment, please refer to Figure 1 and Figure 5 The infrared heating module also includes a mounting plate 5 for hanging the lampshade 1. One end of the mounting plate 5 is connected to the metal sleeve 410, and the other end of the mounting plate 5 is connected to the physical structure, thereby facilitating the fixation of the infrared heating module.

[0050] In one embodiment, please refer to Figure 2 and Figure 6 The infrared heating module also includes two heat conducting plates 6 and multiple springs 7. The two heat conducting plates 6 are arranged in the accommodating space and are respectively attached to the opposite sides of the infrared lamp tube 2. The springs 7 are squeezed and clamped between the heat conducting plates 6 and the inner side of the lampshade 1.

[0051] The elasticity of the provided springs 7 pushes the two sets of heat conducting plates 6 to fix the infrared lamp 2 in the middle, which can buffer and fix the infrared lamp 2. The heat conducting plates 6 are made of aluminum alloy, and the springs 7 are made of copper or silver alloy, both of which have high thermal conductivity, so that the heat of the infrared lamp 2 can be conducted to the surface of the lampshade 1, so that the heat energy generated by the infrared lamp 2 can be dissipated in time, effectively preventing heat energy accumulation and avoiding the infrared lamp 2 from being broken due to excessive surface temperature.

[0052] In one embodiment, please refer to Figures 1 to 3 The infrared heating module also includes a cooling plate 8, which is attached to the outer surface of the lampshade 1. A flow channel for cooling liquid is provided in the cooling plate 8, and a liquid inlet 810 and a liquid outlet 820 communicating with the flow channel are respectively provided at both ends of the cooling plate 8.

[0053] Specifically, the cooling liquid in the cooling plate 8 can exchange heat with the lampshade 1, thereby cooling the lampshade 1, thereby dissipating the heat energy generated by the infrared lamp tube 2 in time, effectively preventing heat energy accumulation, and avoiding the infrared lamp tube 2 from breaking due to excessive surface temperature.

[0054] According to another aspect of the present application, an embodiment of the present application further provides a coating system, which includes the infrared heating module as described above.

[0055] In the embodiment of the present application, the coating system includes the infrared heating module as described above. When the infrared lamp tube 2 breaks, the fragments are not easy to splash out, which effectively ensures the safety of production equipment and operators, reduces the risk of explosion of related components of the coating system, and improves the safety performance of the coating system.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
