[0052] With reference to Figures 2-5 The end of the positioning pipe 5 away from the supporting plate 2 is provided with a limiting assembly 8, the limiting assembly 8 limits the partition plate 4 during the rotation of the inner cylinder 12, so that the fiber cement board 3 is separated for maintenance, it is worth mentioning that the limiting assembly 8 comprises a magnetic plate 81, an iron block 82, a serpentine rod 83 and a clamping block 84, the serpentine rod 83 comprises a straight rod part and a curved rod part, one end of the serpentine rod 83 is slidably connected to the positioning pipe 5 through a return spring 85, the magnetic plate 81 is fixedly connected to the lower half of the inner side of the kiln body 11, the other end of the serpentine rod 83 is arranged through the cooperation of the iron block 82 and the magnetic plate 81, the clamping block 84 is popped out and clamped to the partition plate 4 through the sliding of the serpentine rod 83, so that the fiber cement board 3 is separated for maintenance.

[0053] Specifically, with reference to Figure 6 The serpentine rod 83 is provided with a groove 831, the clamping block 84 is fixedly connected with a spherical block 841, the spherical block 841 and the groove 831 are slidably connected, the maximum diameter size of the spherical block 841 is greater than the opening diameter size of the groove 831, so that the serpentine rod 83 can push the clamping block 84 to pop out of the positioning pipe 5 during the sliding process, and then clamp the partition plate 4, the spacing between adjacent clamping blocks 84 is greater than the spacing between adjacent partition plates 4 in the initial position, so that the fiber cement board 3 is separated, and the fiber cement board 3 is facilitated to be fully maintained.

[0054] The operation principle of the present application will be described as follows:

[0055] When the device is used, the workers process raw materials such as silica sand and wood pulp, stir them through a stirrer, mix into fiber cement slurry, and then press into groups of fiber cement boards 3 after sieving and water separation, the fiber cement boards 3 are cut into specific sizes, sent into the kiln body 11 through the supporting plate 2, and then subjected to steam curing and strengthening.

[0056] With the slow passage of steam inside the kiln body 11, until the ambient temperature inside the kiln body 11 rises to about 60℃ - warming stage (the warming rate varies according to the time of the static stage, the longer the early pre-nurturing time of the product, the higher the initial structural strength, and the warming rate can be correspondingly increased; otherwise, slow warming is required. In autumn and summer, the warming rate should be controlled at about 25℃ per hour; in spring and winter, it should be controlled at about 15℃ per hour. If obvious cracks appear on the surface of the product, the warming rate should be reduced). With the increase of the steam temperature inside the kiln body 11, the petroleum ether liquid inside the hydraulic pipe 731 of the trigger assembly 7 volatilizes, pushing the piston plate 732 to move towards one end of the conductive block 733 until the piston plate 732 and the conductive block 733 are in contact, realizing the conduction of the motor 71. At this time, the motor 71 drives the inner cylinder 12 and the kiln body 11 to rotate through the meshing of the gear 721 and the tooth ring 722, until the supporting plate 2 is turned over from the bottom of the kiln body 11 to the top of the kiln body 11, and the motor 71 stops working. During this process, when the inner cylinder 12 rotates with the trigger assembly 7, the iron block 82 of the limiting assembly 8 changes direction from vertical upwards - horizontal - vertical downwards. When the iron block 82 gradually approaches the area where the magnetic plate 81 is located, it will cause the iron block 82 to slide the serpentine rod 83 and the positioning pipe 5 under the action of magnetic attraction and its own gravity, and then push the clamping block 84 out of the positioning pipe 5 to clamp the partition plate 4. Since the distance between adjacent clamping blocks 84 is greater than the distance between adjacent partition plates 4 in the initial position, the fiber cement board 3 is separated, facilitating the full curing of the fiber cement board 3.

[0057] After the curing temperature inside the kiln body 11 is maintained for a certain period of time, high-temperature steam is introduced to make the ambient temperature reach 80℃ - constant temperature stage (the higher the steam temperature and the longer the curing time in the constant temperature stage, the faster the strength development of the product and the higher the final strength obtained). After a certain period of time, the specified curing effect is achieved, and the kiln body 11 is slowly stopped, uniformly cooled, and kept humid - cooling stage (in autumn and summer, the cooling rate should be controlled at about 25℃ per hour; in spring and winter, it should be controlled at about 15℃ per hour. The time used is determined according to the production cycle, and the longer the cooling stage time, the better). During this process, the motor 71 drives the inner cylinder 12 to reset under the action of the trigger assembly 7, and the iron block 82 of the limiting assembly 8 is retracted under the action of the reset spring 85 after moving away from the magnetic plate 81 by a certain distance (when the iron block 82 changes direction to horizontal - vertical upwards, the action of the fiber cement board 3 on the clamping block 84 decreases). until the fiber cement board 3 returns to the initial position. When the fiber cement board 3 completes the curing work within a specified time, the staff takes out the reinforced fiber cement board 3 by opening the kiln door, and after checking the strength, it can perform the final paint spraying work. Thus, the plate making process of the fiber composite wallboard is completed.

[0058] The above merely describes preferred specific embodiments of the present application, and all embodiments cannot be enumerated here, but the protection scope of the present application is not limited thereto, any person skilled in the art, according to the technical solution and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, should be covered within the protection scope of the present application.
