Detailed Implementation

[0023] The present invention will be further described in detail below with reference to embodiments: Example 1

[0024] like Figure 1-6 As shown, this utility model provides a heating device for the production of thermoplastic polymer foam boards, including a heating box, which includes an insulated box 11. The insulated box 11 has an insulated box door 12 on its front side. A support rod 13 is fixedly connected to the bottom of the inner cavity of the insulated box 11, and a fixing rod 14 is fixedly connected to the top of the support rod 13. The heating mechanism includes a first heating component 21 and a second heating component 22. The top of the first heating component 21 is fixedly connected to the top of the inner cavity of the insulated box 11, and the bottom of the second heating component 22 is fixedly connected to the bottom of the inner cavity of the insulated box 11.

[0025] In this embodiment, by opening the insulation box door 12, the thermoplastic polymer foam board 18 is placed on top of the support frame 17. The support frame 17 is slidably connected to the first guide rod 15 via a slider 16, allowing for flexible adjustment of the foam board's position. After placement, the insulation box door 12 is closed. Then, the heating mechanism is activated. The first heating tube of the first heating component 21 and the first heating tube 222 of the second heating component 22 simultaneously begin operation, heating the foam board inside the insulation box 11 from the top and bottom respectively, achieving simultaneous heating from both above and below, thus improving heating efficiency and uniformity. Example 2

[0026] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heating chamber includes an insulated box 11, with an insulated box door 12 on the front of the insulated box 11, a support rod 13 fixedly connected to the bottom of the inner cavity of the insulated box 11, and a fixing rod 14 fixedly connected to the top of the support rod 13; the heating mechanism includes a first heating component 21 and a second heating component 22, with the top of the first heating component 21 fixedly connected to the top of the inner cavity of the insulated box 11, and the bottom of the second heating component 22 fixedly connected to the bottom of the inner cavity of the insulated box 11; the heating chamber also includes a first guide rod. 15. Two sets of first guide rods 15 are provided. The two ends of the first guide rods 15 are fixedly connected to the surface of the fixed rods 14. A slider 16 is slidably connected to the surface of the first guide rods 15. A support frame 17 is fixedly connected to the top of the slider 16. A thermoplastic polymer foam board 18 is provided on the top of the support frame 17. The heating mechanism also includes a motor 23. The surface of the motor 23 is fixedly connected to the surface of the heat preservation box 11. A threaded rod 24 is fixedly connected to one end of the motor 23 shaft. A mounting bracket 25 is threadedly connected to the surface of the threaded rod 24. A second guide rod 26 is slidably connected inside the mounting bracket 25.

[0027] In this embodiment, during the heating process, the motor 23 starts, and its shaft drives the threaded rod 24 to rotate. Since the mounting frame 25 is threadedly connected to the threaded rod 24 and has a second guide rod 26 slidably connected inside, and the end of the second guide rod 26 is fixed to the inner wall of the insulation box 11, the mounting frame 25 moves linearly along the direction of the second guide rod 26 under the rotation of the threaded rod 24. The second heating tube 27 fixed to the inner wall of the mounting frame 25 moves accordingly to supplement the heating of different positions of the foam board, further ensuring the uniformity of heating. Example 3

[0028] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heating box includes an insulated box 11, an insulated box door 12 is provided on the front of the insulated box 11, a support rod 13 is fixedly connected to the bottom of the inner cavity of the insulated box 11, and a fixing rod 14 is fixedly connected to the top of the support rod 13; the heating mechanism includes a first heating component 21 and a second heating component 22, the top of the first heating component 21 is fixedly connected to the top of the inner cavity of the insulated box 11, the bottom of the second heating component 22 is fixedly connected to the bottom of the inner cavity of the insulated box 11, the end of the second guide rod 26 is fixedly connected to the inner wall of the insulated box 11, a second heating tube 27 is fixedly connected to the inner wall of the mounting frame 25, the second heating component 22 includes a mounting frame 221 and a first heating tube 222, the two ends of the first heating tube 222 are fixedly connected to the inner wall of the mounting frame 221, and the structure of the second heating component 22 is the same as that of the first heating component 21.

[0029] In this embodiment, the insulation structure on the outside of the insulation box 11 plays a role throughout the heating process, reducing heat loss and improving energy utilization. Once the foam board reaches the predetermined heating effect, the heating components and motor 23 are turned off, the insulation box door 12 is opened again, and the heated thermoplastic polymer foam board 18 is taken out, completing one production cycle.

[0030] The working principle of the heating device used in the production of thermoplastic polymer foam boards will be explained in detail below.

[0031] like Figure 1-6 As shown, first open the insulated box door 12, place the thermoplastic polymer foam board 18 on top of the support frame 17. The support frame 17 is slidably connected to the first guide rod 15 through the slider 16, so that the position of the foam board can be flexibly adjusted. After placement, close the insulated box door 12. Next, the heating mechanism is activated. The first heating tube of the first heating component 21 and the first heating tube 222 of the second heating component 22 start working simultaneously, heating the foam board inside the insulation box 11 from the top and bottom respectively, achieving simultaneous heating from top to bottom, improving heating efficiency and uniformity. During the heating process, the motor 23 starts, and its shaft drives the threaded rod 24 to rotate. Since the mounting frame 25 is threadedly connected to the threaded rod 24 and has a second guide rod 26 slidably connected inside, with the end of the second guide rod 26 fixed to the inner wall of the insulation box 11, the mounting frame 25 moves linearly along the direction of the second guide rod 26 under the rotation of the threaded rod 24. The second heating tube 27 fixed to the inner wall of the mounting frame 25 moves accordingly, supplementing heating at different positions of the foam board, further ensuring heating uniformity. Throughout the heating process, the insulation structure on the outside of the insulation box 11 plays a role in reducing heat loss and improving energy utilization. When the foam board reaches the predetermined heating effect, the heating components and motor 23 are turned off, the insulation box door 12 is opened again, and the heated thermoplastic polymer foam board 18 is taken out, completing one production cycle.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
