Technical Field

[0001] This utility model relates to the field of paper humidification technology, specifically to an automatic humidification device. Background Technology

[0002] In the paper production and processing, the moisture content of the base paper directly affects subsequent processing stages such as forming and printing. If the moisture content of the base paper is too low, the paper may become brittle and easily torn, affecting the quality of the finished product and processing efficiency; therefore, it is necessary to humidify the base paper.

[0003] Chinese patent CN222065029U discloses an automatic humidification device for raw paper. It includes a support frame with a roller assembly, a heating device, and a spray device. The roller assembly has support blocks and rollers. A lifting frame has a heating roller and an air outlet for heating the raw paper. A rotating spray head is installed inside the atomization box. The raw paper enters the atomization box via a spray conveyor belt for humidification. By first heating and controlling the moisture content of the raw paper to a uniform level, and then uniformly humidifying it, the humidification effect is more efficient.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: when the raw paper with a low moisture content passes through the rollers and heating device before being humidified by the spray device, the moisture loss of the raw paper will be more serious, the paper will be more brittle and prone to cracking, resulting in the loss of raw paper and affecting the humidification efficiency. Utility Model Content

The second humidification mechanism has the same structure as the first humidification mechanism but different dimensions. The structure consists of a distribution pipe mounted on the casing and multiple sets of atomizing nozzles evenly installed on the bottom of the outer circumference of the distribution pipe.

Two sets of the first guide rollers are arranged parallel to each other between the paper roll and the second humidification mechanism. A first infrared moisture meter is located above the two sets of first guide rollers.

[0008] Preferably, the number of atomizing nozzles at the output end of the split pipe in the first humidification mechanism is less than the number in the second humidification mechanism, and the spray volume of the atomizing nozzles in the first humidification mechanism is less than the spray volume in the second humidification mechanism.

[0009] Preferably, the tensioning mechanism includes a second guide roller, which is rotatably connected to the housing via a motor drive, and the second guide roller is located behind the first guide roller; a first U-shaped frame, on which a tensioning roller is rotatably connected via a motor drive, the tensioning roller being distributed between the first guide roller and the second guide roller, and the installation height of the tensioning roller relative to the bottom of the housing is higher than the installation height of the first guide roller and the second guide roller relative to the bottom of the housing; and an elastic rod, which is installed at the top of the first U-shaped frame, and the elastic rod is connected to the top of the housing via a connecting rod.

[0011] Preferably, the inner wall of the ironing roller is provided with multiple sets of baffles, which are evenly and alternately distributed along the inner wall of the ironing roller.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This utility model first detects the humidity of the raw paper using a first infrared moisture meter. For raw paper with a humidity value exceeding the set threshold, it is directly ironed and flattened at a suitable temperature by a flattening mechanism to bring its humidity value to the set safety threshold. For raw paper with a humidity value lower than the set threshold, it is first pre-humidified by a first humidification mechanism, then its tension is increased by a tensioning mechanism, and finally its humidity is refined by a second humidification mechanism.

[0018] Example 1, as Figures 1 to 4As shown, this utility model proposes an automatic humidification device, including a housing 1, a first humidification mechanism, a first infrared moisture meter 4, a second humidification mechanism tensioning mechanism, a leveling mechanism, and a second infrared moisture meter 7. A paper roller 2 is driven to rotate at the feed end of the housing 1 by a motor. The first humidification mechanism is installed at the top of the inner wall of the housing 1, with its input end connected to a humidifier at the top of the housing 1 and its output end corresponding to the paper roller 2. The first infrared moisture meter 4 is located behind the paper roller 2. The second humidification mechanism is installed at the top of the inner wall of the housing 1 and located behind the first infrared moisture meter 4. Its input end is connected to a water supply mechanism at the top of the housing 1. The second humidification mechanism has the same structure as the first humidification mechanism but different dimensions. The first humidification mechanism is installed by a tensioning mechanism, a leveling mechanism, and a second infrared moisture meter 7. The machine consists of a distribution pipe 5 on the casing 1 and multiple sets of atomizing nozzles 501 evenly installed on the bottom of the outer periphery of the distribution pipe 5. The distribution pipe 5 is connected to the top of the machine inside the casing 1 through a bracket. A solenoid valve 502 is provided between the atomizing nozzles 501 and the distribution pipe 5. The input end of the distribution pipe 5 is connected to the humidifier through a hose. The tensioning mechanism is located between the raw paper roller 2 and the second humidification mechanism. The leveling mechanism is located behind the second humidification mechanism. The leveling mechanism consists of a support roller 6 and an adjustable ironing roller 602 located above the support roller 6. The support roller 6 is driven to rotate by a motor installed on the casing 1. The input end of the ironing roller 602 is connected to a hot air supply mechanism located at the top of the casing 1. The output end of the ironing roller 602 is provided with an air outlet 603. The second infrared moisture meter 7 is located at the discharge end of the casing 1.

[0019] Furthermore, a first guide roller 3 is connected to the inner wall of the casing 1 by a motor drive. Two sets of the first guide roller 3 are arranged in parallel between the paper roll 2 and the second humidification mechanism. The first infrared moisture meter 4 is located above the two sets of first guide rollers 3. The two sets of first guide rollers 3 can flatten the paper after preliminary humidification, making it easier for the first infrared moisture meter 4 to detect the paper humidity.

[0020] Furthermore, the number of atomizing nozzles 501 at the output end of the split pipe 5 in the first humidification mechanism is less than that in the second humidification mechanism, and the spray volume of the atomizing nozzles 501 in the first humidification mechanism is less than that in the second humidification mechanism.

[0021] Furthermore, the tensioning mechanism includes a second guide roller 301, a first U-shaped frame 303, and an elastic rod 302. The second guide roller 301 is rotatably connected to the housing 1 via a motor drive. The second guide roller 301 is located behind the first guide roller 3, and the top height of the outer circumferential surface of the second guide roller 301 is on the same horizontal plane as the top height of the outer circumferential surface of the support roller 6. A tension roller 304 is rotatably connected to the first U-shaped frame 303 via a motor drive. The tension roller 304 is distributed between the first guide roller 3 and the second guide roller 301, and the installation height of the tension roller 304 relative to the bottom of the housing 1 is higher than the installation height of the first guide roller 3 and the second guide roller 301 relative to the bottom of the housing 1. The elastic rod 302 is installed at the top of the first U-shaped frame 303 and is connected to the top of the housing 1 via a connecting rod. The elastic rod 302 consists of a telescopic rod installed between the first U-shaped frame 303 and the connecting rod, and a spring sleeved on the outside of the telescopic rod.

[0022] Furthermore, a second U-shaped frame 601 is installed at the top of the ironing roller 602 housing 1 via a hydraulic rod. The output end of the ironing roller 602 is rotatably connected to the second U-shaped frame 601 via a motor drive. The input end of the ironing roller 602 is rotatably connected to a connecting pipe 604. The connecting pipe 604 is installed at the other end of the second U-shaped frame 601. The connecting pipe 604 is connected to the hot air supply mechanism via a hose. A clearance opening 101 corresponding to the connecting pipe 604 is provided on the side wall of the housing 1.

[0023] In this embodiment, the paper roll 2 containing the raw paper is installed on the machine housing 1. The end of the raw paper contacts the bottom of the outer periphery of the two sets of first guide rollers 3, then passes through the tensioning mechanism and the second humidification mechanism. The raw paper then passes between the ironing roller 602 and the support roller 6. Finally, the raw paper extends from the bottom of the second infrared moisture meter 7 to the outside of the discharge end of the machine housing 1 and connects with the external traction mechanism. The moisture content of the raw paper between the two sets of first guide rollers 3 is detected by the first infrared moisture meter 4. When the moisture content is lower than the set safety threshold, the controller opens an appropriate number of solenoid valves 502 on the diversion pipe 5 according to the moisture content of the raw paper. Water is supplied to the first humidification mechanism through the water supply mechanism at the top of the machine housing 1. The water is evenly sprayed onto the raw paper on the paper roll 2 by multiple atomizing nozzles 501, thereby achieving the effect of pre-humidifying the raw paper with low moisture content by spraying a small amount of water, avoiding damage caused by cracking during subsequent conveying. After preliminary humidification, the raw paper passes around the tension roller 304 and the second guide roller 3. 01. Under the self-adjusting action of the elastic rod 302, the paper's tension can be adjusted at any time, allowing it to smoothly enter the leveling mechanism. The controller starts the second humidification mechanism to refine and humidify the raw paper by spraying water. The hydraulic rod drives the ironing roller 602 to move down and press the raw paper against the support roller 6. At the same time, the support roller 6 and the ironing roller 602 are started to roll and flatten the raw paper. According to the humidity requirements of the raw paper, the hot air supply mechanism delivers hot air of appropriate temperature to the connecting pipe 604. The hot air enters the ironing roller 602 to heat it, and then the ironing roller 602 irons and flattens the humidified raw paper, which is convenient for subsequent processing. The second infrared moisture meter 7 performs the final humidity test on the humidified and ironed raw paper. If the test is qualified, the raw paper is output. If the test is unqualified, the raw paper is reversed and humidified again. When the first infrared moisture meter 4 detects that the humidity of the raw paper on the raw paper roller 2 is higher than the set safety threshold, it can be directly ironed and flattened at an appropriate temperature by the leveling mechanism.

[0024] Example 2, as Figure 4 As shown, the automatic humidification device proposed in this utility model, compared with the first embodiment, has multiple sets of baffles 605 on the inner wall of the ironing roller 602. The multiple sets of baffles 605 are evenly and alternately distributed along the inner wall of the ironing roller 602, and the baffles 605 are set as incomplete circular plates.

[0025] In this embodiment, the hot air stays inside the ironing roller 602 for a longer period of time by using multiple sets of staggered baffles 605, which makes it easier to heat the ironing roller 602 fully and thus make it easier to iron and flatten the humidified paper.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
