Description

Technical Field

[0001] This utility model relates to the field of cardboard processing equipment, and in particular to a humidification device for corrugated cardboard processing. Background Technology

[0002] In existing technologies, corrugated cardboard is humidified during processing to achieve the required humidity level, which is beneficial for its production. Current humidification devices often use atomizing nozzles to spray water mist onto the cardboard surface. However, during processing, water droplets frequently fall from the atomizing nozzles, and the water mist distribution is uneven, resulting in inconsistent and uneven humidification of the cardboard, which negatively impacts the processing of the corrugated cardboard. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a humidification device for corrugated cardboard processing, which can uniformly humidify the cardboard and improve its processing performance.

[0004] This utility model discloses a humidification device for corrugated cardboard processing, including two side support plates. Rollers are rotatably mounted at both ends between the two side support plates, and a conveyor belt is wound around the two rollers. A drive motor is fixed to one of the side support plates at the end of one of the rollers, and the drive motor is connected to the corresponding roller. A water mist output pipe is arranged between the side support plates above the conveyor belt, with both ends of the water mist output pipe sealed to the side support plates. A water mist output hole is arrayed in the middle of the side wall of the water mist output pipe, facing the output direction of the cardboard on the conveyor belt. A water mist conveying pipe extends inward from one end of the water mist output pipe. A mist delivery pipe connects to a water mist source and a conveying fan. The outer diameter of the mist delivery pipe is smaller than the inner diameter of the mist output pipe. A downward through hole is provided on the lower side wall of the mist delivery pipe inside the mist output pipe. A drain pipe is provided on the lower side wall of the mist output pipe at one end, and the drain pipe is connected to the inside of the mist output pipe. A top plate is provided on the top of the side support plate, and an air outlet is provided on the top plate. The air outlet is elongated and its length is along the width of the conveyor belt. The air outlet is located in front of the mist output pipe. A wind box is provided above the top plate. The air outlet is located within the wind box and is connected to the inside of the wind box. A blower is connected to the wind box through a pipe.

[0005] The conveyor belt has several hollow structures arranged in an array.

[0006] A partition is provided between the side support plates on the side of the water mist output pipe. The partition is sealed to the top plate. There is a gap between the lower end of the partition and the conveyor belt, which allows the cardboard to pass through.

[0007] A water removal hood is installed between the side support plates below the conveyor belt. The two ends of the water removal hood are sealed to the side support plates. The water removal hood is open on the side facing the conveyor belt. The side wall of the water removal hood on the front side of the conveyor belt in the conveying direction is in contact with the lower surface of the conveyor belt. There is a gap between the side wall of the water removal hood on the rear side of the conveyor belt in the conveying direction and the lower surface of the conveyor belt. An exhaust pipe is installed at the bottom of the water removal hood, and an exhaust fan is installed on the exhaust pipe.

[0008] The humidification device for corrugated cardboard processing obtained by this utility model inputs water mist into the water mist output pipe through the water mist delivery pipe and delivers it outward from the water mist output hole. The airflow in the air box is directed downward, so that the water mist is evenly delivered to the cardboard. This can effectively prevent water droplets from falling from the water mist delivery pipe and the water mist output pipe during the water mist delivery process. The water droplets can be discharged from the drain pipe, which greatly improves the uniformity of cardboard humidification. Attached Figure Description

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1:

[0016] like Figures 1-5As shown, this utility model discloses a humidification device for corrugated cardboard processing, including two side support plates 1, with rollers 2 rotatably mounted at both ends between the two side support plates 1. A conveyor belt 4 is wound around the two rollers 2. A drive motor 3 is fixed on the side support plate 1 at one end of one of the rollers 2, and the drive motor 3 is connected to the corresponding roller 2. A water mist output pipe 5 is arranged between the side support plates 1 above the conveyor belt 4. The two ends of the water mist output pipe 5 are sealed to the side support plates 1. A water mist output hole 7 is arrayed in the middle of the side wall of the water mist output pipe 5, and the water mist output hole 7 faces the output direction of the cardboard 15 on the conveyor belt 4. A water mist conveying pipe 6 is inserted from one end of the water mist output pipe 5. A water mist source and a conveying fan are connected. The outer diameter of the water mist conveying pipe 6 is smaller than the inner diameter of the water mist output pipe 5. A downward through hole 16 is provided on the lower side wall of the water mist conveying pipe 6 inside the water mist output pipe 5. A drain pipe 9 is provided on the lower side wall of the water mist output pipe 5 at one end. The drain pipe 9 is connected to the inside of the water mist output pipe 5. A top plate 12 is provided on the top of the side support plate 1. An air outlet 17 is provided on the top plate 12. The air outlet 17 is elongated and its length is along the width of the conveyor belt 4. The air outlet 17 is located in front of the water mist output pipe 5. A wind box 8 is provided above the top plate 12. The air outlet 17 is located within the wind box 8 and is connected to the inside of the wind box 8. A blower 14 is connected to the wind box 8 through a pipe.

[0017] Two side support plates 1 serve as the main support structure of the equipment. The rollers 2 are rotatably mounted on the side support plates 1 and are parallel to each other. One roller 2 is driven by a drive motor 3 to transmit power around the conveyor belt 4 mounted on it. During the transmission of the conveyor belt 4, the cardboard 15 moves forward with it. The water mist source can be water mist generated by atomized spraying or water mist generated by ultrasonic vibration; both are existing known technologies and are not specifically limited. The water mist from the water mist source is conveyed from the water mist conveying pipe 6 to the water mist output pipe 5 via a conveying fan. The water mist in the water mist output pipe 5 is then output outwards through the water mist output hole 7. The through hole 16 of the water mist conveying pipe 6 delivers water mist into the water mist output pipe 5 and then outwards through the water mist output hole 7 on its side. During this process, water mist accumulates on the side walls of the water mist delivery pipe 6 and the water mist output pipe 5, forming water droplets. The water droplets in the water mist delivery pipe 6 enter the water mist output pipe 5 through the through-hole 16, while the water droplets generated in the water mist output pipe 5 slide down its inner wall to the bottom of the water mist output pipe 5 and are eventually discharged outwards through the drain pipe 9. Of course, a control valve can be installed on the drain pipe 9 for intermittent opening. This ensures that the collection and discharge of the generated water droplets does not affect the water mist delivery process, and the water droplets will not drip onto the cardboard 15, causing uneven humidification of the cardboard 15. This greatly improves the humidification performance of the cardboard 15, ensuring a uniform and reliable humidification process. Additionally, a bellows 8 is installed on the top plate 12, and an air outlet 17 is arranged within the bellows 8. The air outlet 17 is elongated and arranged along the width direction of the conveyor belt 4. The air outlet 17 is located in front of the water mist output pipe 5, meaning in the direction in which the conveyor belt 4 transports the cardboard 15. Simultaneously, the water mist output holes 7 on the water mist output pipe 5 also face in front of the direction in which the conveyor belt 4 transports the cardboard 15, i.e., the transport direction of the upper conveyor belt 4. The water mist output from the water mist output pipe 5 is carried downwards by the airflow blown down by the bellows 8 above it and quickly falls onto the cardboard 15. Because the air outlet 17 is elongated, it can cover the entire width direction of the cardboard 15, thus maintaining uniform and stable humidification of all parts of the cardboard 15.

[0018] The conveyor belt 4 has several perforated structures 13 arranged in an array. The airflow from the through holes 16 and vents 17 on the conveyor belt 4 can be discharged outwards from the top of the conveyor belt 4, while also passing through the conveyor belt 4, preventing an increase in internal air pressure. Simultaneously, water droplets generated on the conveyor belt 4 can be discharged through the perforated structures 13, preventing localized increases in humidity on the cardboard 15 on the conveyor belt 4. The specific shape of the perforated structures 13 can be selected according to actual needs, and can be circular, rhomboid, polygonal, etc.

[0019] A partition 18 is provided between the side support plates 1 on the side of the water mist output pipe 5. The partition 18 is sealed to the top plate 12, and there is a gap between the lower end of the partition 18 and the conveyor belt 4, which allows the cardboard 15 to pass through. The partition 18 effectively prevents water mist from spreading to the input end of the cardboard 15 on the conveyor belt 4, thus preventing unstable humidification of the cardboard 15. Therefore, the partition 18 can improve the uniformity and stability of humidification of the cardboard 15.

[0020] A dewatering hood 10 is provided between the side support plates 1 below the conveyor belt 4. The two ends of the dewatering hood 10 are sealed to the side support plates 1. The dewatering hood 10 is open on the side facing the conveyor belt 4. The side wall of the dewatering hood 10 on the side facing forward of the conveyor belt 4 in the conveying direction is in contact with the lower surface of the conveyor belt 4. There is a gap between the side wall of the dewatering hood 10 on the side facing backward of the conveyor belt 4 in the conveying direction and the lower surface of the conveyor belt 4. An exhaust pipe is provided at the bottom of the dewatering hood 10, and an exhaust fan 11 is provided on the exhaust pipe.

[0021] In actual use, some water mist will inevitably fall onto the conveyor belt 4, forming water droplets. Of course, the amount of water droplets on the conveyor belt 4 is significantly reduced compared to existing technologies. However, to further avoid the impact of these small amounts of water droplets on the uniformity of humidification of the cardboard 15, a desiccant hood 10 is installed below the conveyor belt 4. The desiccant hood 10 has an opening at its top, and there is a gap between one side of the desiccant hood 10 and the lower surface of the conveyor belt 4. This allows water droplets on the conveyor belt 4 to enter the desiccant hood 10 along with the conveyor belt 4. The other side of the desiccant hood 10 contacts the lower surface of the conveyor belt 4, where the water droplets are blocked as they pass through the other side wall of the desiccant hood 10 and enter the desiccant hood 10. Simultaneously, the desiccant hood 10 is connected to an exhaust fan 11, enabling internal airflow to dry the lower surface of the conveyor belt 4. Furthermore, since the amount of water droplets is small, drainage is unnecessary; the water entering the desiccant hood 10 is discharged from the exhaust fan 11 with the airflow.
