Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a cardboard humidification device for corrugated cardboard production. Background Technology

[0002] As a basic material in the packaging industry, the production quality of corrugated cardboard directly affects the compressive strength, flexibility, and forming qualification rate of cartons. During the cardboard processing, especially in processes such as slitting, creasing, and folding, if the moisture content of the cardboard is too low, it will cause the paper to become brittle, easily break or crack at the indentation, leading to problems such as increased scrap rate and increased production costs. To solve these problems, corrugated cardboard production lines generally use humidification devices to improve the paper's flexibility and folding resistance by spraying water mist onto the cardboard surface or adjusting the humidity of the workshop. Humidification technology has become a key link in ensuring the forming quality of cardboard and reducing the scrap rate.

[0003] Existing devices generally lack mechanisms for recycling excess water. Whether it's water that drips but isn't absorbed by the cardboard during spraying, or water droplets that condense and drip after atomization, this results in a significant waste of water resources. This is inconsistent with the current industry trend of green production and energy conservation. In the long run, wastewater discharge will also increase the production and operating costs of enterprises. Therefore, we need to propose a cardboard humidification device for corrugated cardboard production. Utility Model Content

[0004] The purpose of this utility model is to provide a paperboard humidification device for corrugated paperboard production. By setting up a conveying roller, a water tank, a first conveying pump, a spray pipe, an adjustment mechanism, a filter plate, a recycling tank, and a conveying assembly, it achieves stable conveying of paperboard, flexible adjustment of the spray distance to ensure humidification quality, and realizes water resource filtration, recycling and reuse, reducing waste and lowering costs, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model can store humidification water in a water tank at the top of the casing. The first delivery pump delivers the water in the tank to the spray pipe through a connecting pipe. The spray pipe humidifies the corrugated cardboard being transported, meeting the basic humidification requirements of the cardboard. Two sets of adjustment mechanisms are respectively set on the inner walls of both sides of the casing, which can flexibly adjust the distance between the spray pipe and the corrugated cardboard. The optimal spray distance can be adapted to corrugated cardboard with different thicknesses and different humidity requirements, which not only ensures the humidification effect and avoids problems such as insufficient humidification due to excessive distance or local over-humidification due to excessive distance, but also improves the adaptability of the device to different production scenarios.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A corrugated cardboard humidification device for corrugated cardboard production includes: a housing 1, on which several sets of conveying rollers 2 are rotatably mounted on the inner walls of both sides. The conveying rollers 2 are evenly distributed along the length of the housing 1, providing stable support and guiding for the corrugated cardboard. A water tank 3 is fixedly connected to the top of the housing 1. The top of the water tank 3 has a filling port and a sealing cap for easy replenishment of humidification water. A first conveying pump 4 is fixedly connected to one side wall of the water tank 3. One end of the first conveying pump 4 is connected to a spray pipe 6 via a connecting pipe 5. The bottom of the spray pipe has several spray holes evenly distributed to allow water to be sprayed evenly. By setting the evenly distributed conveying rollers 2 and the spray pipe 6 with spray holes, the device achieves stable conveying of the cardboard and uniform humidification. Simultaneously, the surface of the conveying rollers 2 can be wrapped with a rubber anti-slip sleeve to further increase the friction between the rollers and the corrugated cardboard, preventing slippage and deviation during conveying, ensuring the cardboard remains directly below the spray pipe 6, and guaranteeing accurate humidification.

[0026] Two sets of adjustment mechanisms 7, used to adjust the distance between the spray pipe 6 and the corrugated cardboard, are respectively set on the inner walls of both sides of the machine housing 1. The two sets of adjustment mechanisms 7 are symmetrically distributed, which can ensure that the spray pipe 6 rises and falls synchronously on both sides, avoiding the spray pipe 6 tilting and affecting the humidification uniformity. By setting the symmetrically distributed adjustment mechanisms 7, the effect of ensuring the smooth adjustment of the spray pipe 6 and improving the consistency of humidification is achieved. In addition, a displacement sensor can be installed on the movable end of the linear module 701. The displacement sensor is connected to an external controller and can provide real-time feedback on the position information of the spray pipe 6, which makes it easier for operators to more accurately control the adjustment distance and meet the humidification distance requirements of corrugated cardboard of different thicknesses.

[0027] The filter plate 8 is inserted into the housing 1. Made of stainless steel, the filter plate 8 has uniformly distributed filter holes on its surface, providing good corrosion resistance and filtration efficiency. A recovery tank 9 is located below the filter plate 8 in the housing 1. The inner wall of the recovery tank 9 is smoothed to reduce moisture residue. A conveying assembly 10 is located on one side of the housing 1 to circulate the recovered liquid from the recovery tank 9 to the water tank 3. By using the stainless steel filter plate 8 and the smooth-walled recovery tank 9, efficient filtration of impurities and reduction of moisture residue are achieved. Furthermore, the pore size of the filter plate 8 can be set to 0.5-1mm, effectively filtering impurities such as cardboard debris without excessively hindering water dripping, ensuring recovery efficiency. The stainless steel material also extends the service life of the filter plate 8, reducing replacement frequency.

[0028] The connecting pipe 5 includes a bend 501. The top end of the bend 501 is fixedly connected to the first delivery pump 4. The bend 501 is made of rigid pipe to ensure the stability of the connection. The bottom end of the bend 501 passes through the housing 1 and is fixedly connected to a corrugated pipe 502. The corrugated pipe 502 has good extensibility. The bottom end of the bend 501 is fixedly connected to the spray pipe 6. By setting the rigid bend 501 and the extensible corrugated pipe 502, the effect of ensuring stable water delivery and adapting to the height adjustment of the spray pipe 6 is achieved. In addition, a protective sleeve can be set on the outer layer of the corrugated pipe 502. The protective sleeve is made of wear-resistant material to prevent the corrugated pipe 502 from being worn during long-term expansion and contraction and use, thus extending its service life. It can also prevent external dust and other impurities from entering the interior of the corrugated pipe 502 and affecting water delivery.

[0029] The adjustment mechanism 7 includes a linear module 701, which is fixedly installed on the inner wall of the housing 1. The control end of the linear module 701 can be connected to an external controller for precise control of the adjustment distance. A mounting block 702 is connected to the movable end of the linear module 701, and the mounting block 702 is fixedly connected to the end of the spray pipe 6. The mounting block 702 and the spray pipe 6 are connected by bolts for easy disassembly and maintenance. By setting up the linear module 701 with an external controller connection end and the bolted mounting block 702, the effect of precise adjustment of the spray distance and easy maintenance is achieved. Furthermore, a rubber gasket can be installed at the connection between the mounting block 702 and the spray pipe 6. The rubber gasket increases the sealing of the connection, preventing water leakage during water supply, and also reduces wear between the mounting block 702 and the spray pipe 6.

[0030] The conveying assembly 10 includes a second conveying pump 1001, which is fixedly connected to one side wall of the housing 1. One end of the second conveying pump 1001 is connected to the interior of the recovery tank 9 via a pipe. The end of the pipe is close to the bottom of the recovery tank 9, allowing for sufficient extraction of the recovery liquid. The other end of the second conveying pump 1001 is fixedly connected to a connecting pipe 1002, the top of which is fixedly connected to a water tank 3. A one-way valve is provided on the connecting pipe 1002 to prevent backflow of water in the water tank 3. By setting the pipe close to the bottom of the recovery tank 9 and the connecting pipe 1002 with a one-way valve, the effect of sufficient water recovery and prevention of backflow is achieved. In addition, the connection between the second conveying pump 1001 and the pipe can be a flange connection. The flange connection has good sealing and stability, preventing leakage during the pumping process and ensuring that the recovery liquid can be smoothly delivered to the water tank 3.

[0031] A slot 11 adapted to the filter plate 8 is provided on one side wall of the housing 1. The inner wall of the slot 11 is equipped with a sealing gasket to reduce water leakage from gaps. The filter plate 8 is inserted into the housing 1 through the slot 11. By setting the slot 11 with the sealing gasket, the installation sealing of the filter plate 8 is improved and water leakage is reduced. At the same time, a stop can be set at the opening of the slot 11. The stop can limit the insertion position of the filter plate 8, ensuring that the filter plate 8 can be accurately installed in the designated position, forming a stable support with the support block 13, and preventing the filter plate 8 from being misaligned, which would affect the filtration and support effect.

[0032] Positioning blocks 12 are fixedly connected to both the filter plate 8 and one side wall of the housing 1. The positions of the two sets of positioning blocks 12 are corresponding, and positioning pins are inserted into the interior of the two sets of positioning blocks 12. The ends of the positioning pins are equipped with pull rings for easy insertion and removal. By setting the positioning blocks 12 with corresponding positions and the positioning pins with pull rings, the filter plate 8 is firmly fixed and easy to disassemble and assemble. In addition, lubricating oil can be applied to the mating parts of the positioning pins and positioning blocks 12. The lubricating oil can reduce the friction when the positioning pins are inserted and removed, making the operation more effortless, and at the same time, it can prevent rust from forming between the positioning pins and positioning blocks 12, which would make disassembly and assembly difficult.

[0033] Support blocks 13 are fixedly connected to the inner walls on both sides of the recycling tank 9. The top of the support blocks 13 is treated with anti-slip material, and the bottom of the filter plate 8 abuts against the top of the support blocks 13, providing stable support for the filter plate 8. By setting the anti-slip support blocks 13, the installation stability of the filter plate 8 is enhanced. Moreover, the support blocks 13 and the inner wall of the recycling tank 9 can be welded together. The welded connection can ensure the connection strength of the support blocks 13, so that they will not loosen or fall off during long-term support of the filter plate 8, further ensuring the installation stability of the filter plate 8.

[0034] Working principle: First, the corrugated cardboard is placed on the conveyor roller 2. The conveyor roller 2 rotates under the drive of the drive device, thereby moving the corrugated cardboard steadily downwards towards the spray pipe 6. The rubber anti-slip sleeve on the surface of the conveyor roller 2 prevents the cardboard from slipping or shifting. The water tank 3 stores humidifying water. When humidification of the cardboard is required, the first conveying pump 4 is started. Under the action of the first conveying pump 4, the water in the water tank 3 is conveyed sequentially through the bend pipe 501 and the corrugated pipe 502 to the spray pipe 6, and then sprayed out through the evenly spaced spray holes at the bottom of the spray pipe 6 to evenly humidify the corrugated cardboard conveyed below.

[0035] If corrugated cardboard of different thicknesses or with different humidity requirements is encountered, the linear module 701 can be controlled by an external controller. The movable end of the linear module 701 drives the mounting block 702 to rise and fall, thereby adjusting the distance between the spray pipe 6 and the corrugated cardboard. The displacement sensor feeds back the position information of the spray pipe 6 to the external controller in real time for precise adjustment. During this process, the corrugated pipe 502 extends and retracts with the movement of the spray pipe 6 to adapt to changes in height, and its outer protective sleeve can protect it.

[0036] During the humidification process, excess water not absorbed by the cardboard drips onto the filter plate 8. The filter holes on the surface of the filter plate 8 filter out impurities such as cardboard fragments from the water. The filtered water passes through the filter plate 8 and falls into the recovery tank 9 below. The smooth inner wall of the recovery tank 9 reduces water residue. Then, the second transfer pump 1001 is started. Under the action of the second transfer pump 1001, the recovered liquid in the recovery tank 9 is transported back to the water tank 3 through the pipe and connecting pipe 1002, realizing the recycling of water resources. The one-way valve on the connecting pipe 1002 can prevent the water in the water tank 3 from flowing back.

[0037] When the filter plate 8 needs cleaning after a period of use, the operator pulls out the positioning pin in the positioning block 12 using the pull ring, and then removes the filter plate 8 from the slot 11 for cleaning. After cleaning, the filter plate 8 is reinserted into the machine housing 1 through the slot 11. The stop block at the opening of the slot 11 limits the filter plate 8, causing its bottom to abut against the top of the support block 13. Finally, the positioning pin is inserted into the positioning block 12 to complete the fixation. The entire device efficiently completes the humidification operation of corrugated cardboard through the coordinated cooperation of its components, and realizes the recycling of water resources, reducing production consumption.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
