Description

Technical Field

[0001] This utility model specifically relates to a corrugated cardboard humidification device for a corrugated paper production line, belonging to the technical field of corrugated paper production equipment. Background Technology

[0002] In the production process of corrugated cardboard, if the humidity of the corrugated cardboard is too low, the crease depth will be insufficient when the slitting and pressing machine presses the cardboard. This will affect the folding during later processing and make it prone to breakage. Therefore, it is necessary to add a humidification device for the corrugated cardboard. By humidifying the corrugated cardboard, the humidity of the corrugated cardboard can be increased, which can increase its softness and avoid the problems of warping, deformation and bursting of the corrugated cardboard. Existing corrugated cardboard humidification devices, such as the corrugated cardboard humidification device for a corrugated cardboard production line disclosed in Chinese Patent Publication No.: CN213261415U, can comprehensively humidify the corrugated cardboard and effectively improve the humidification efficiency. However, the humidification device of this structure cannot be well integrated with the corrugated cardboard production line, and the existing humidification device cannot precisely control the humidification area of ​​the corrugated cardboard. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a corrugated cardboard humidification device for a corrugated paper production line. This device can be well integrated with the corrugated paper production line and can perform both unified global humidification and targeted local humidification according to humidification requirements.

[0004] The corrugated cardboard humidification device for a corrugated paper production line of this utility model includes: A water collection tank, with a first atomizing tube assembly installed inside the water collection tank; the bottom of the water collection tank is connected to a water tank via a drain pipe. The atomizing hood has a second atomizing tube assembly installed inside it. Paper guide rollers are mounted on both sides of the second atomizing tube assembly via bearings, with the bottom of the paper guide rollers lower than the bottom surface of the atomizing hood. A slide block is fixed to the output side of the atomizing hood, and an infrared proximity switch is slidably fixed on the slide block. During operation, according to the requirements of the spray area, the housing of the infrared proximity switch is slidably mounted on the slide block and secured to the slide block by a nut on the housing block. The atomizing tube assembly includes a pressure pump fixed to a water tank. The input end of the pressure pump is connected to the inside of the water tank, and the output end of the pressure pump is connected to a tee. The other two ends of the tee are connected to a first atomizing tube assembly and a second atomizing tube assembly respectively through solenoid valves. The pressure pump draws water from the water tank and sends it to the tee for diversion, and then into the solenoid valves to sequentially enter the first atomizing tube assembly and the second atomizing tube assembly. The water collection trough is located between the transmission rollers; the atomizing hood is located directly above the water collection trough; when excess water droplets are atomized, they are sent back into the water tank through the water collection trough. The infrared proximity switch, pressure pump, and solenoid valve are connected to the controller.

[0005] During operation, the pressure pump operates at two frequencies, high and low. Under normal conditions, the pressure pump operates at the low frequency, drawing water to the first and second atomizing tube groups to achieve overall atomization and humidification of the corrugated paper. When the corrugated paper reaches the position where creases are needed, it is triggered by an infrared proximity switch, which slows down the drive roller group. At the same time, the pressure pump operates at the high frequency, resulting in high power output from the pressure pump, increasing the atomization and humidification amount at the crease position of the corrugated paper, and ensuring the crease depth.

[0006] Furthermore, the first atomizing tube assembly and the second atomizing tube assembly include a tube body, one end of which is sealed and the other end is connected to a solenoid valve. A row of atomizing nozzles is fixed on the tube body. A pressure pump draws water into the tube body, and the pressurized water is atomized and sprayed out through the atomizing nozzles, thereby atomizing and humidifying the top and bottom surfaces of the corrugated cardboard.

[0007] Furthermore, the atomizing hood is fixed with ear holes at all four ends, and a support column is fixed on the roller frame of the transmission roller assembly. An adjusting nut is screwed onto the upper part of the support column, and the ear holes are slidably installed with the support column. The bottom of the ear holes is pressed against the adjusting nut. The adjusting nut can adjust the gap between the atomizing hood and the water collection tank, allowing the paper guide roller to press against the top surface of the corrugated cardboard. Thus, when the corrugated cardboard enters the bottom surface of the atomizing hood, the paper guide roller can limit the top surfaces of both sides of the corrugated cardboard. When the second atomizing tube assembly performs atomization humidification, the paper guide roller can isolate both sides, preventing droplets from entering the outside of the humidification area.

[0008] Furthermore, the transmission roller assembly includes a conveyor belt, a transverse roller frame, and two vertical roller frames; each vertical roller frame is equipped with two intermediate transmission rollers, and the transverse roller frame is equipped with two input transmission rollers and two output transmission rollers; the conveyor belt is sequentially looped around the input transmission rollers, the two upper intermediate transmission rollers, the output transmission rollers, the two lower intermediate transmission rollers, and the input transmission rollers to form a closed loop; one of the output transmission rollers is connected to a drive motor via a coupling; the drive motor is connected to a controller; the controller sends a signal to the drive motor, and the drive motor drives one output transmission roller to rotate, thereby realizing the synchronous operation of the input transmission rollers, intermediate transmission rollers, and conveyor belt to transfer corrugated cardboard.

[0009] Furthermore, the transverse roller frame is equipped with an output pair of rollers on the output side of the output drive roller via a bracket, and the output pair of rollers scrape off the fog droplets on the surface of the corrugated cardboard.

[0010] Furthermore, the transmission roller assembly is connected to the transmission line of the corrugated paper production line. The corrugated cardboard that has been processed at the front end enters the transmission roller assembly, and is humidified by the first atomizing tube assembly and the second atomizing tube assembly at the transmission roller assembly. After humidification is completed, the transmission roller assembly exports the corrugated cardboard and sends it to the next process through the transmission line.

[0011] Furthermore, the top surface of the conveyor belt is flush with the top surface of the water collection tank. When the conveyor belt transports the corrugated cardboard above the water collection tank, the corrugated cardboard can form a closed surface on the water collection tank, thereby achieving closed-loop atomized humidification.

[0012] Compared with the prior art, the corrugated cardboard humidification device for the corrugated paper production line of this utility model can be well integrated with the corrugated paper production line. When humidifying the corrugated paper, the humidification device adopts closed humidification and can perform global humidification and targeted humidification of the corrugated paper.

[0021] Example 1: like Figures 1 to 7 The corrugated cardboard humidification device shown in the diagram for a corrugated paper production line includes: Water collection tank 1, with a first atomizing tube assembly 2 installed inside the water collection tank 1; the bottom of the water collection tank 1 is connected to the water tank 4 through a drain pipe 3; Atomizing hood 5, with a second atomizing tube assembly 6 installed inside the atomizing hood 5, and paper guide rollers 7 arranged on both sides of the second atomizing tube assembly 6 via bearings, the bottom of the paper guide rollers 7 being lower than the bottom surface of the atomizing hood 5; a slide block 8 is fixed on the output side of the atomizing hood 5, and an infrared proximity switch 9 is slidably fixed on the slide block 8; during operation, according to the requirements of the spray area, the housing of the infrared proximity switch 9 is slidably set on the slide block 8, and is pressed and positioned by the nut on the housing against the slide block 8; The atomizing tube assembly includes a pressure pump 10 fixed to a water tank 4. The input end of the pressure pump 10 is connected to the inside of the water tank 4, and the output end of the pressure pump 10 is connected to a tee 11. The other two ends of the tee 11 are connected to a first atomizing tube assembly 2 and a second atomizing tube assembly 6 respectively through solenoid valves 12. The pressure pump 10 draws water from the water tank 4 and sends it to the tee 11 for diversion, and then enters the solenoid valve 12 to enter the first atomizing tube assembly 2 and the second atomizing tube assembly 6 in sequence. The water collection tank 1 is located between the transmission rollers; the atomizing cover 5 is located directly above the water collection tank 1; when excess water droplets are atomized, they are sent back into the water tank 4 through the water collection tank 1. The infrared proximity switch 9, pressure pump 10, and solenoid valve 12 are connected to the controller.

[0022] During operation, the pressure pump 10 operates at two frequencies, high and low. Under normal conditions, the pressure pump 10 operates at the low frequency, pumping water to the first atomizing tube group 2 and the second atomizing tube group 6, thereby achieving overall atomization and humidification of the corrugated paper. When the corrugated paper reaches the position where creases are required, it is triggered by the infrared proximity switch 9, which slows down the transmission roller group. At the same time, the pressure pump 10 operates at the high frequency, thus outputting high power to increase the atomization and humidification amount at the crease position of the corrugated paper and ensure the crease depth.

[0023] The first atomizing tube group 2 and the second atomizing tube group 6 include a tube body 13. One end of the tube body 13 is sealed, and the other end is connected to a solenoid valve 12. A row of atomizing nozzles 14 are fixed on the tube body 13. The pressure pump 10 draws water into the tube body 13, and the pressurized water is atomized and sprayed out through the atomizing nozzles 14, thereby atomizing and humidifying the top and bottom surfaces of the corrugated cardboard.

[0024] The atomizing hood 5 is fixed with ear hole seats 15 at all four ends. The roller frame of the transmission roller group is fixed with a support column 16. The upper part of the support column 16 is screwed with an adjusting nut 17. The ear hole seats 15 and the support column 16 are slidably installed. The bottom of the ear hole seats 15 is pressed into the adjusting nut 17. The adjusting nut 17 can realize the gap between the atomizing hood 5 and the water collection tank 1, so that the paper guide roller 7 can press against the top surface of the corrugated cardboard. Thus, when the corrugated cardboard enters the bottom surface of the atomizing hood 5, the paper guide roller 7 can limit the top surfaces of the corrugated cardboard on both sides. When the second atomizing tube group 6 performs atomization humidification, the paper guide roller 7 can isolate both sides to prevent the mist droplets from entering the outside of the humidification area.

[0025] The transmission roller assembly includes a conveyor belt 18, a transverse roller frame 19, and two vertical roller frames 20. Each vertical roller frame 20 is equipped with two intermediate transmission rollers 21, and the transverse roller frame 19 is equipped with two input transmission rollers 22 and two output transmission rollers 23. The conveyor belt 18 is sequentially looped around the input transmission rollers 22, the two upper intermediate transmission rollers 21, the output transmission rollers 23, the two lower intermediate transmission rollers 21, and the input transmission rollers 22 to form a closed loop. One of the output transmission rollers 23 is connected to a drive motor via a coupling. The drive motor is connected to a controller. The controller sends a signal to the drive motor, which drives one output transmission roller 23 to rotate, thereby enabling the input transmission rollers 22, the intermediate transmission rollers 21, and the conveyor belt 18 to move synchronously and transfer the corrugated cardboard.

[0026] The transverse roller frame 19 is equipped with an output roller pair 24 on the output side of the output drive roller 23 via a bracket. The output roller pair 24 scrapes away the fog droplets on the surface of the corrugated cardboard.

[0027] The drive roller assembly is connected to the drive line of the corrugated paper production line. The corrugated cardboard that has been processed at the front end enters the drive roller assembly and is humidified by the first atomizing tube assembly 2 and the second atomizing tube assembly 6 at the drive roller assembly. After humidification, the drive roller assembly outputs the corrugated cardboard and sends it to the next process through the drive line.

[0028] The top surface of the conveyor belt 18 is flush with the top surface of the water collection tank 1. When the conveyor belt 18 conveys the corrugated cardboard above the water collection tank 1, the corrugated cardboard can form a closed surface on the water collection tank 1, thereby realizing closed-loop atomization humidification.

[0029] The above embodiments are merely preferred embodiments of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model are included within the scope of the present utility model.
