[0024] Refer to Figures 1 to 5, in the embodiment of the present utility model, an automatic adjustment device for a hot plate of a corrugated production line includes: a main housing 1, an operation chamber 2 is provided inside the main housing 1, a steam generator 3 is fixedly connected above the main housing 1, an air pump 4 is fixedly connected above the main housing 1 close to the steam generator 3, a partition plate 5 is fixedly connected inside the operation chamber 2, a steam heating and compaction mechanism 6 is fixedly connected inside the operation chamber 2, two groups of moisture exhaust fans 7 are fixedly connected inside the operation chamber 2, a conveyor belt 8 is arranged below the operation chamber 2, and a corrugated board 9 to be processed is arranged above the conveyor belt 8;

[0025] The steam heating and compaction mechanism 6 includes electric telescopic rods 61, the number of the electric telescopic rods 61 is two groups, the electric telescopic rods 61 are fixedly connected inside the operation chamber 2, the movable ends of the electric telescopic rods 61 are fixedly connected with a heating plate 62, a heating plate 62 is fixedly connected below the electric telescopic rods 61, a heating tube 63 is fixedly connected inside the heating plate 62, the heating tube 63 is connected to an external power supply through an electric wire, a punching mesh plate 64 is fixedly connected below the heating plate 62, side fixing blocks 65 are fixedly connected on both sides of the heating plate 62, a limiting sliding hole 66 is opened in the side fixing block 65, a fixed base 68 is arranged below the side fixing block 65, a limiting sliding rod 67 is fixedly connected above the fixed base 68, a support spring 69 is sleeved outside the limiting sliding rod 67, a compaction roller 610 is rotatably connected below the fixed base 68, the number of the side fixing blocks 65 and the fixed bases 68 is two groups respectively, two groups of limiting sliding holes 66 are opened in each group of side fixing blocks 65, two groups of limiting sliding rods 67 are fixedly connected above each group of fixed bases 68, the limiting sliding rods 67 are adapted to the limiting sliding holes 66, a stop block is fixedly connected above the limiting sliding rods 67 to prevent the limiting sliding rods 67 from sliding out of the limiting sliding holes 66, the fixed base 68 is slidably connected with the side fixing block 65 through the limiting sliding rod 67, the air outlet end of the steam generator 3 is communicated with the air inlet end of the air pump 4 through a pipeline, the air outlet end of the air pump 4 is communicated with the inside of the heating plate 62 through a pipeline, and the steam heating and compaction mechanism 6 and the two groups of moisture exhaust fans 7 are respectively located at both ends of the partition plate 5.

[0026] The working principle of the present utility model is: when the steam generator 3 is started, steam enters the air pump 4 through a pipeline, the air pump 4 transports the steam to the inside of the heating plate 62. At the same time, the heating tube 63 inside the heating plate 62 is connected to an external power supply and starts to heat, rapidly increasing the temperature of the steam inside the heating plate 62 through the electrothermal heating method. The high-temperature heat is uniformly transferred to the corrugated board 9 to be processed below through the punching mesh plate 64 along with the high-temperature steam. The uniform punching of the punching mesh plate 64 ensures that the heat can be evenly distributed, avoiding the problems of local overheating or underheating of the corrugated board. By controlling the air pump 4, the heating intensity can be precisely adjusted to adapt to different corrugated boards and fixing glues;

[0027] During the heating process, the electric telescopic rod 61 adjusts its length according to preset processing parameters or the instructions of the operator. Through precise control, the heating plate 62 can adjust the distance from the corrugated board 9 to be processed, ensuring that heat can be transferred to the corrugated board more directly and effectively. Also, the compaction roller 610 is adjusted to fit the corrugated board 9 to be processed, and pressure is applied by the compaction roller 610 below to compact the corrugated board 9 to be processed, enhancing its structure and performance. The coordinated operation of the compaction roller 610 and the heating plate 62 ensures a good bonding effect while the corrugated board is being heated. When the compaction roller 610 compacts the corrugated board 9 to be processed, the support spring 69 can provide a certain buffering effect, reducing the direct impact of the compaction roller 610 on the corrugated board 9 to be processed, preventing damage to the corrugated board 9 to be processed caused by the direct pressure of the electric telescopic rod 61, and providing a uniform and stable compaction effect;

[0028] During the heating and compaction processes, the two groups of dehumidifying fans 7 inside the operation chamber 2 start to work. By generating a strong airflow, they discharge the excess moisture generated during the heating process from the operation chamber 2, keeping the operation environment dry and clean. This dehumidifying design not only improves the processing quality of the corrugated board but also extends the service life of the device.

[0029] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
