[0015] The specific embodiments of the utility model will be further explained in detail in combination with the drawings, in which:

[0016] Figure 1 is the three-dimensional structure schematic view of the utility model;

[0017] Figure 2 is the exploded schematic view of the utility model;

[0018] Figure 3 is the working principle schematic view of the cold flame spray painting machine. DETAILED DESCRIPTION

[0019] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0020] The embodiment discloses a heating system of a cold flame spraying machine. Figures 1 to 3 The system has simple structure, convenient installation, can realize uniform heating of cold flame materials, and has excellent safety, reliability and maintainability. Compared with the traditional electromagnetic heating mode, the heating system provided by the utility model has lower price, smaller size and higher practicability.

[0021] As shown in Figure 1 and Figure 2 , the heating system mainly comprises a conveying pipe 1 for conveying cold flame materials and a plurality of independent heating modules 2. The conveying pipe 1 is a hollow tubular structure for conveying cold flame materials to the spray pipe. The heating module 2 is sleeved on the outer surface of the conveying pipe 1 and is responsible for heating the cold flame materials in the pipe.

[0022] Each heating module 2 has the same structure and is composed of three key components: a ceramic sleeve 21 in the shape of a circular tube, a heating coil 22 wound around the outer periphery of the ceramic sleeve 21 and a terminal 23 connected to both ends of the heating coil 22.

[0023] The ceramic sleeve 21 is made of high-temperature-resistant ceramic material and has good thermal conductivity and insulation. This double feature ensures that heat can be effectively transferred to the cold flame materials in the conveying pipe 1, while avoiding safety risks such as electric leakage. The inner diameter of the ceramic sleeve 21 is slightly larger than the outer diameter of the conveying pipe 1, so that it can be tightly attached to the outer surface of the conveying pipe 1, ensuring the stability and uniformity of heating.

[0024] The heating coil 22 is tightly wound around the outer periphery of the ceramic sleeve 21 and is the core component of the heating system. In order to further improve the safety, the surface of the resistance wire of the heating coil 22 is coated with a layer of high-temperature-resistant insulating paint. This layer of insulating paint not only prevents short circuit, but also plays a role in heat preservation and fixing the resistance wire, further improving the stability and service life of the heating system. The terminal 23 is connected to both ends of the heating coil 22 and is used to connect the external power supply to provide the required electric energy for the heating coil 22.

[0025] A big highlight of the utility model lies in its modular design. The plurality of heating modules 2 are connected through series connection mode, and constitute complete heating system. This design is not limited by the length of the conveying pipe 1, and has very high flexibility. The user can flexibly increase or decrease the number of heating modules 2 according to the actual length of the conveying pipe 1, ensure that the conveying pipe 1 is evenly heated, and avoid the situation of local overheating or insufficient heating. In addition, the modular design greatly improves the maintainability of the system. Once a heating module 2 fails, only the damaged module needs to be replaced, without replacing the entire system, greatly reducing the maintenance cost and time.

[0026] In order to facilitate the series installation of the module and isolate the heat escape between adjacent modules, high-temperature-resistant ceramic spacers 3 are arranged between the ceramic sleeves 21 of adjacent heating modules 2. Figure 1 And Figure 2 As shown in the drawings, in order to further improve the convenience and stability of installation, the ceramic sleeve 21 is respectively provided with a radially outwardly extending annular partition plate 211 at the left and right ends, and one or more fixing columns 212 are uniformly distributed on the partition plate 211. Correspondingly, the left and right side surfaces of the ceramic spacer 3 are provided with fixing holes 31 corresponding in number and position to the fixing columns 212. Through the plug-in cooperation of the fixing columns 212 and the fixing holes 31, the adjacent ceramic sleeves 21 and ceramic spacers 3 are firmly connected together to form a stable heating module assembly. In order to avoid assembly errors, the fixing columns 212 at the left and right ends of the same ceramic sleeve 21 are staggered in the circumferential direction, and the positions and sizes of the corresponding fixing columns 212 on different ceramic sleeves 21 remain consistent.

[0027] In addition, in order to further enhance the fixing stability of the heating module assembly on the conveying pipe 1, at least one positioning through hole 32 is further arranged on the outer side surface of the ceramic spacer 3, which is used for penetrating a fastener (such as a bolt or a screw) and being fixed on the conveying pipe 1, to ensure that the entire heating system is stable and reliable.

[0028] Figure 3 As shown in the drawings, the principle schematic diagram of the cold flame spray painting machine clearly shows the installation position and function of the conveying pipe 1 and the heating system, and further illustrates the technical scheme of the utility model.

[0029] In summary, the cold flame spray painting machine heating system provided by the embodiment effectively solves the problems of high cost, large size, poor adaptability, inconvenient maintenance and the like of the traditional heating system, and provides an efficient, safe, reliable and economical heating solution for the cold flame spray painting machine field.
