[0001] This invention relates to the field of material coating production technology, specifically to a heating and curing equipment for a heat-insulating and flame-retardant protective film coating. Background Technology

[0002] The thermosetting process of general flame-retardant film materials mainly involves thermally initiated chemical cross-linking. Its core objective is to construct a three-dimensional network structure to lock the flame-retardant components in the polymer matrix, thereby obtaining durable, stable and non-migrating flame-retardant properties.

[0003] During the curing process, the membrane material is usually placed in an environment with a temperature between 180-220 degrees Celsius and then removed after curing for a certain period of time. However, if the membrane material is in a roll, it will lead to uneven curing. If the membrane material is in a moving state, the temperature inside the curing equipment will easily change due to the airflow when the membrane material is removed, resulting in a waste of thermal energy.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figure 1-5 As shown, a heat-insulating and flame-retardant protective film coating heating and curing device includes a curing chamber 2, which is symmetrically arranged. The upper part of the curing chamber 2 is separated into a first curing zone 1, and the lower part is separated into a second curing zone 6. An isolation device is provided between the first curing zone 1 and the second curing zone 6, and the isolation device is installed in a U-shaped cavity 10. A transfer device for winding and moving the film material 19 is provided in the first curing zone 1 and the second curing zone 6. In use, by heating the first curing zone 1 and the second curing zone 6 respectively, the temperature of both the first curing zone 1 and the second curing zone 6 is kept between 180-220 degrees Celsius, thereby enabling sufficient curing of the film material 19. In this application, by using the film material 19 for winding, i.e., by using the transfer device, the film material 19 can be moved back and forth between the first curing zone 1 and the second curing zone 6. The membrane material 19 is moved, allowing it to traverse two curing zones during the movement, ensuring sufficient contact with the temperature and further enhancing the curing effect. Furthermore, the use of an isolation device in this application separates the first curing zone 1 and the second curing zone 6. If either the first or second curing zone 1 malfunctions, the membrane material 19 cures within the intact curing zone. When moving to the other curing zone, an additional ultraviolet curing device 13 is installed to fully cure the membrane material 19. During the movement from the intact curing zone, the membrane material 19 is sufficiently cooled, allowing for ultraviolet curing. Therefore, this application ensures both the integrity of the membrane material 19 during curing and the full curing of the membrane material 19 even if one curing zone is damaged.

[0022] As a further embodiment of this application, the transfer device includes a take-up roller 16, with an inner guide roller 15 rotatably disposed on the outer side of the take-up roller 16. The inner guide roller 15 is rotatably mounted inside the curing chamber 2, while the take-up roller 16 is mounted on the output end of a power motor, which drives the take-up roller 16. A third outer guide roller 18 is disposed outside the inner guide roller 15, a second outer guide roller 17 is disposed on the side of the third outer guide roller 18, and a first outer guide roller 14 is disposed at the bottom of the second outer guide roller 17. The first outer guide roller 14 and the second outer guide roller 17 are on the same vertical line, and an ultraviolet curing device 13 can be installed on the side of the first outer guide roller 14 and the second outer guide roller 17. The ultraviolet curing device 13 is detachably installed on the device mounting plate 12, which is fixedly installed inside the curing chamber 2. In use, the first outer guide roller 14 and the second outer guide roller 17 are on the same vertical line, so that the ultraviolet curing device 13 can uniformly and fully cure the film material 19.

[0023] Furthermore, an outer power roller 20 is provided on the side of the first outer guide roller 14, wherein the outer power roller 20 is installed inside the curing chamber 2 by a motor. At the same time, the third outer guide roller 18 is fixed on the rotating shaft 21, which is rotatably mounted on the sliding limit plate 25. The sliding limit plate 25 is slidably mounted inside the sliding seat 22. The sliding seat 22 has an internal groove 23, and a tension spring 24 is fixed inside the internal groove 23. The output end of the tension spring 24 is fixed to the sliding limit plate 25. In use, by adjusting the position of the first outer guide roller 14, the tension of the film material 19 can be adjusted, thereby adjusting the position of the film material 19.

[0024] As a further embodiment of this application, the isolation device includes an isolation groove 4, which is located on the side of the curing chamber 2. An adjustment base 9 is fixed inside the U-shaped cavity 10, and an adjustment telescopic rod 8 is fixed inside the adjustment base 9. The output end of the adjustment telescopic rod 8 passes through the adjustment groove 7, which is located on the curing chamber 2. An isolation support 3 is fixed to the output end of the adjustment telescopic rod 8. An isolation roller 5 is rotatably mounted on the side of the isolation support 3. The isolation roller 5 cooperates with the isolation groove 4, and the membrane material 19 passes through the isolation roller 5. In use, the isolation roller 5 is moved and placed inside the isolation groove 4. At this time, the isolation baffle 11 is close to the edge of the curing chamber 2, leaving only a small gap for the membrane material 19 to pass through, thereby reducing heat entering another curing zone and reducing heat loss.

[0025] To achieve the winding function of the take-up roller 16, the take-up roller 16 includes a take-up body 26. To achieve this function, a mounting groove 37 is provided on the take-up body 26. Side grooves 27 are symmetrically provided on both sides of the mounting groove 37. A side spring 28 is fixed inside the side groove 27. A side sliding plate 29 is fixed to the output end of the side spring 28. A sliding arc-shaped end 35 is fixed to the end of the side sliding plate 29. To clamp the film material 19, a perforation is provided on the mounting plate 31 for the film material to pass through. On the back of the mounting plate 31, the clamping spring 32 causes the clamping rods 39 to act in opposite directions, allowing the clamping plate 38 installed at the end of the clamping rods 39 to clamp the film material 19. Therefore, the clamping rods 39 are slidably mounted on the mounting plate 31, and the clamping rods 39 and the clamping plate 38 are fixedly connected. The outer surface of the mounting plate 31 is arc-shaped, designed to cooperate with the winding body 26. The mounting plate 31 has a mating groove 34 on its side, and an arc-shaped end 33 at the end of the mating groove 34 for cooperating with the sliding arc-shaped end 35. The bottom of the mounting plate 31 has a pressing protrusion 30, which is inclined towards the side facing the sliding arc-shaped end 35. Therefore, in use, the clamping rod 39 is first moved backward to clamp the film material 19 with the clamping plate 38. Then, the mounting plate 31 is placed inside the mounting groove 37. At this time, under the action of the pressing protrusion 30, the sliding arc-shaped end 35 is compressed and moves into the mating groove 34. Under the action of the side spring 28, the sliding arc-shaped end 35 moves into the arc-shaped end 33. At this time, the outer surface of the mounting plate 31 and the winding body 26 cooperate to form a complete arc shape.

[0026] In use, the present invention first moves the clamping rod 39 backwards, clamping the membrane material 19 with the clamping plate 38. Then, the mounting plate 31 is placed inside the mounting groove 37. Under the action of the extrusion protrusion 30, the sliding arc-shaped end 35 is compressed, moving into the mating groove 34. Under the action of the side spring 28, the sliding arc-shaped end 35 moves into the arc-shaped end 33. At this point, the outer surface of the mounting plate 31 and the winding body 26 cooperate to form a complete arc. Subsequently, the membrane material 19 is wound up, i.e., using a transfer device, allowing the membrane material 19 to move back and forth between the first curing zone 1 and the second curing zone 6. This allows the membrane material 19 to pass through both curing zones during movement, ensuring sufficient contact with the temperature and further improving the curing effect. Furthermore, the use of the isolation device in this application can... The first curing zone 1 and the second curing zone 6 are separated. If either the first curing zone 1 or the second curing zone 6 malfunctions, the membrane material 19 will be cured in the intact curing zone. When moving to the other curing zone, the membrane material 19 will be fully cured by an additional ultraviolet curing device 13. During the movement of the membrane material 19 from the intact curing zone, it can be cooled down sufficiently, thus enabling ultraviolet curing. Therefore, this application can ensure the integrity of the membrane material 19 during curing and also ensure that the membrane material 19 is fully cured even if a certain curing zone is damaged. When the isolation device is in use, the isolation roller 5 is moved and placed inside the isolation groove 4. At this time, the isolation baffle 11 is close to the edge of the curing box 2, leaving only a small gap for the membrane material 19 to pass through, thereby reducing the heat entering the other curing zone and reducing heat loss.
