[0029] The following is combined with Figure 1-5 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0030] The present application discloses a carton steam humidification device:

[0031] Reference Figure 2 and Figure 4-5 A carton steam humidification device includes a frame 1, a paper feeding assembly 2, a working box 3 and a plurality of steam nozzles 4. The working box 3 is fixed above the frame 1, and a steam pipe 5 is provided in the working box 3. One end of the steam pipe 5 is connected to the plurality of steam nozzles 4, and the other end is connected to a steam source. The plurality of steam nozzles 4 are arranged in multiple rows and installed on the bottom surface of the working box 3. The paper feeding assembly 2 is installed on the frame 1 and is used to transport carton boards 30 to the bottom of the steam nozzles 4. The straight line formed by the steam nozzles 4 is perpendicular to the paper feeding direction. After the paper feeding assembly 2 delivers the carton boards 30 to the bottom surface of the working box 3, the steam nozzles 4 spray steam onto the carton boards 30, thereby increasing the moisture content of the carton boards 30 and reducing the occurrence of cracks and breaks in the carton boards 30 during subsequent folding. The steam provided by the steam source is steam that has been dehydrated and dried at high temperature, which reduces the possibility that the humidified carton boards 30 are overly moist due to excessive moisture content in the steam, thereby affecting the subsequent folding and printing processes.

[0032] Reference Figure 4-5 A plurality of air flow nozzles 6 are installed on the bottom surface of the working box 3, and an air flow duct 7 is installed in the working box 3. One end of the air flow duct 7 is connected to the plurality of air flow nozzles 6, and the other end is connected to the air source. The plurality of air flow nozzles 6 are arranged in a straight line and distributed on both sides of the straight line formed by the steam nozzles 4. The air flow nozzles 6 are arranged in a straight line parallel to the straight line formed by the steam nozzles 4. The air flow nozzles 6 form an air curtain on both sides of the steam nozzles 4, so that the steam ejected from the steam nozzles 4 will not spread to both sides and affect other components through the guidance of the air curtain. At the same time, the air curtain also reduces the situation where the external cold air approaches the steam nozzles 4 during operation and condenses on it to form condensed water, causing part of the carton board 30 to be over-wetted by the dripping condensed water.

[0033] Reference Figure 4A venturi pipe 8 and several condensed water pipes 9 are also installed in the working box 3. The air inlet end of the venturi pipe 8 is connected to the air flow pipe 7. One end of the several condensed water pipes 9 is connected to the venturi pipe 8, and the other end is connected one-to-one with several steam nozzles 4. The air outlet end of the venturi pipe 8 is connected to the sewer pipe. Due to the high steam temperature, the temperature of the steam nozzle 4 will be higher than the ambient temperature, and the humidity at the steam nozzle 4 will also be higher than the normal environment. After the work is completed, a large amount of condensed water will be generated at the steam nozzle 4, and it will drip down and affect other components. The condensed water at the bottom of the steam nozzle 4 can be extracted by the siphon effect of the Venturi effect through the venturi pipe 8, so that the steam nozzle 4 will not have condensed water accumulation, and the phenomenon of water spraying at the steam nozzle 4 after the work is completed will be reduced.

[0034] Reference Figure 1-3 The paper feeding assembly 2 includes a track 21, a baffle 22, a placement platform 23, and a drive device. The track 21 is installed directly below the working box 3, which is located in the middle section of the track 21. The placement platform 23 is located outside one end of the track 21; the baffle 22 is located between the steam nozzle 4 and the placement platform 23, with a gap of the thickness of a carton board 30 left between the bottom surface of the baffle 22 and the track 21; one end of the carton board 30 is placed on the track 21, and the other end is placed on the placement platform 23, with the end of the carton board 30 placed on the track 21 abutting against the baffle 22; the drive device is used to drive the track 21. By utilizing the cooperation between the track 21 and the baffle 22, the carton boards 30 are fed one by one by the track 21 to the bottom of the steam nozzle 4, and then carried out of the working range of the steam nozzle 4 by the track 21 to the next working area. The drive device can use a motor to drive the track 21 to rotate.

[0035] Reference Figure 2-5 A vacuum cleaner 10 is mounted on the frame 1 and is located between the steam nozzle 4 and the baffle 22. Several vacuum heads 101 are mounted on the bottom of the vacuum cleaner 10. A vacuum duct 103 is provided within the vacuum cleaner 10. One end of the vacuum duct 103 is connected to the exhaust device, and the other end is connected to the several vacuum heads 101. A gap the thickness of a carton board 30 is left between the bottom of the vacuum cleaner 10 and the crawler 21. The vacuum cleaner 10 is used to remove dust and debris that may be on the carton board 30, preventing the dust and debris from being wetted by steam and adhering to the carton board 30, which could affect the subsequent printing process.

[0036] Reference Figure 3 and Figure 5 The bottom surface of the vacuum cleaner 10 is also equipped with a plurality of rotating wheels 102, whose outer circumferences abut against the top surface of the carton board 30. The rotating wheels 102 are used to assist the carton board 30 in passing through the vacuum cleaner 10. Since the vacuum cleaner 10 generates an upward suction force, the rotating wheels 102 abut the carton board 30 against the crawler 21 to prevent the carton board 30 from being pulled away from the crawler 21 by the suction force, which would reduce the transport efficiency of the crawler 21.

[0037] Reference Figure 1 Two electric cylinders 20 are mounted on the frame 1, one on each side of the track 21 and located between the baffle 22 and the platform 23. The telescopic rods of the two cylinders 20 face each other and face the carton board 30. Pushing blocks 201 are mounted on the telescopic rods of the cylinders 20 to align the edges of the carton board 30. By limiting the telescopic range of the two electric cylinders 20, they can be extended and retracted to push the pushing blocks 201, aligning the ends of the carton board 30 placed on the track 21. This reduces the risk of the carton board 30 skewing and blocking the track 21.

[0038] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
