Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1: The specific structure of this utility model is as follows:

[0032] Please refer to the appendix. Figure 1-2 The present invention provides a heating device suitable for composite membrane materials, comprising a box-type housing 100 and a heating component.

[0033] The box-type housing 100 is a box-shaped structure composed of a base plate 1, two side plates 2, a viewing window 3, a rear plate 4, a cover plate 5, and an upper mounting plate 16. The front side of the box-type housing 100 (i.e., the viewing window 3) serves as a viewing window for the interior of the box-type housing 100. An electrode flange 6, a vacuum gauge 7 for testing the vacuum level inside the box-type housing 100, and a vacuum connection pipe 8 communicating with the interior of the box-type housing 100 are mounted on the rear side of the box-type housing 100. The rear side of the box-type housing 100 includes the rear plate 4 and the cover plate 5. The rear plate 4 has a window, and the cover plate 5 is installed at the window. The electrode flange 6, vacuum gauge 7, and vacuum connection pipe 8 are mounted on the cover plate 5. Two vacuum gauges 7 are provided.

[0034] Both sides of the box-type housing 100 are connected to air connection pipes 19. One of the air connection pipes 19 is used as an air inlet pipe, and the other air connection pipe 19 is used as an air outlet pipe. The inner openings of the air inlet pipe and the air outlet pipe are both facing the upper cavity of the rectifier plate 12. After the air is supplied through the air inlet pipe and the air outlet pipe, the heat in the cavity can be evenly distributed.

[0035] The heating assembly is located inside the box-type housing 100. From bottom to top, the heating assembly includes multiple flatly arranged ceramic heaters 10, an intermediate plate 9, and a rectifier plate 12. The intermediate plate 9 has ventilation holes distributed on its surface, and its lower surface is connected to multiple ceramic heaters 10 via multiple clips. The rectifier plate 12 is connected to the intermediate plate 9, and a space is left between the rectifier plate 12 and the intermediate plate 9. The surface of the rectifier plate 12 has rectifier holes distributed on its surface. Figure 1 As shown, the ceramic heater 10 has six groups.

[0036] The intermediate plate 9 is divided into multiple ventilation zones, each edge of which is framed and fixed by pipes. At least two pipes have first mounting posts 14 on their upper surfaces, and the lower surface of the rectifier plate 12 is connected and fixed to each of the first mounting posts 14. Each ventilation zone has an oblong hole and three rows of round holes. The top of each first mounting post 14 has a stepped edge, which is fixed to the rectifier plate 12 with screws after positioning.

[0037] like Figure 1 As shown, the lower surface of the intermediate plate 9 is provided with six sets of retaining spring structures, which enable quick installation and removal of the ceramic heater 10, making installation and removal convenient.

[0038] The upper surface of the rectifier plate 12 is provided with a plurality of second mounting posts 13. The top of the second mounting post 13 is a ring of steps, which are fixed to the upper mounting plate 16 by screws after being positioned.

[0039] The ceramic heater 10 is electrically connected to a terminal block 11, and the electrode flange 6 is electrically connected to the terminal block 11. For example... Figure 1 As shown, there are two terminals 11, which are the bus sockets for each ceramic heater 10. There are two sets of electrode flanges 6, which are electrically connected to the two terminals 11 one-to-one through the lines.

[0040] The top surface of the box-type housing 100 is provided with at least one set of temperature sensing devices. The top surface of the box-type housing 100 has two openings spaced apart, and each opening is equipped with an infrared quartz window 18. There are two sets of temperature sensing devices, both of which are infrared temperature sensors, and the temperature probes of the two sets of infrared temperature sensors are pointed one-to-one at the two infrared quartz windows 18.

[0041] The infrared temperature sensing device includes a connector 17 and a temperature sensor 15. One end of the connector 17 is fixed to the upper mounting plate 16, and the other end is raised and connected to the temperature sensor 15, which is an infrared temperature sensor. The infrared temperature sensor is used to detect the temperature inside the box-type housing 100 in real time.

[0042] After the membrane material is fixed, when the heating device heats it, the air inlet pipe on the side plate 2 starts to blow air. After the gas passes through the rectifier plate 12 inside the cavity, the air inside the cavity flows evenly through the ceramic heater 10, thereby making the temperature inside the cavity rise evenly.

[0043] In summary, the heating device of this invention adds a rectifier plate 12 to ensure uniform distribution of hot airflow inside the cavity, thereby achieving uniform heating of the membrane material on the cavity surface. The heating source of this invention uses a ceramic heater 10, enabling rapid heating of the cavity and increasing its maximum temperature. This heating device effectively solves the problems of uneven heat dissipation, slow heating speed, and inability to function properly in high-temperature environments inherent in existing heating methods.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
