Description

Technical Field

[0001] The utility model belongs to the technical field of paper production equipment, and in particular relates to a paper rehumidification device. Background Art

[0002] In the paper production process, it is very important to control the moisture content of paper, because paper is a highly hydrophilic material, and the change of its moisture content will directly affect the performance and quality of paper. In the prior art, the atomization humidification of paper is used, which easily leads to uneven rewetting of paper. Utility Model Content

[0003] The purpose of the utility model is to provide a paper rehumidification device to address the above-mentioned technical problems. The device rehumidifies paper in a box and is equipped with an atomizing component, a mist dispelling component and a humidity sensor, which can effectively control the humidity in the box and ensure uniform rehumidification of the paper.

[0004] In view of this, the utility model provides a paper rehumidification device, including a box body, openings are arranged on both sides of the box body, paper sheets are passed through the openings, a liquid inlet pipe is passed through the top of the box body, one end of the liquid inlet pipe is connected to an external liquid supply device, and the other end is connected to an atomization component in the box body, the atomization component moistens the paper sheets passing through the box body, a humidity control component is also arranged in the box body, the humidity control component includes a humidity sensor arranged in the box body, and the temperature sensor is electrically connected to an external control center, a collecting plate is arranged in the box body, the collecting plate is located below the opening, and a mist removal component is arranged above the collecting plate.

[0005] In the present technical solution, the paper sheets, under the action of the rewinding and unwinding components (not shown) arranged externally, pass through the box through openings on both sides of the box. The atomizing component sprays atomized water to rehumidify the paper sheets through the box. When the humidity sensor senses that the humidity in the box exceeds the preset value, the mist dispelling component pushes the water mist inside the box downward and contacts the collecting plate. The water mist is further deposited on the collecting plate and merged until it drips downward from the collecting plate due to gravity, thereby controlling the humidity in the box and ensuring uniform rehumidification of the paper sheets.

[0006] In the above technical solution, further, the mist-removing component includes a bellows with a hollow structure, the bellows is arranged on the top wall inside the box, a plurality of air outlets are arranged at the lower end of the bellows, the bellows is connected to an air inlet duct, and the other end of the air inlet duct passes through the box to connect to an external air supply device.

[0007] In this technical solution, the air supply device is a common fan or air pump. When the air supply device is started, the air enters the bellows through the air inlet duct and is blown out from the air outlet at the bottom of the bellows, blowing the water mist in the box downward to contact the collection plate, and the water mist is deposited and dripped on the collection plate to control the humidity in the box. In the embodiment, there are two bellows, which are symmetrically arranged on both sides of the atomization component. The bottom of the bellows is provided with equidistant strip air outlets to ensure uniform air output and fully drive the water mist in the box to move.

[0008] In the above technical solution, further, the atomization assembly includes an atomization box, the top of the atomization box is connected to the liquid inlet pipe, and the bottom of the atomization box is provided with a plurality of mounting holes, and the atomization generator is connected to the mounting holes.

[0009] In the above technical solution, further, the mounting hole is provided with an internal thread, and a mounting plate is provided on the back of the atomizer generator corresponding to the mounting hole.

[0010] In the above technical solution, further, it also includes a blocking block, which can be threadedly connected to the mounting hole to block the mounting hole.

[0011] In this technical solution, the atomizer generator is a prior art, so it will not be described in detail. The atomizer box is a hollow structure, which is connected to an external liquid supply device through a liquid inlet pipe. The liquid supply device can be a water pump. Water enters the atomizer box and is sprayed downward through the atomizer generator threadedly installed at the bottom of the atomizer box to rehumidify the paper passing under the atomizer box. The atomizer box extends along the direction of paper sheet transmission, and the mounting holes are equidistantly arranged at the bottom of the atomizer box. Depending on the rehumidification requirements, the atomizer generator or the blocking block can be threaded in the mounting hole, which can also achieve the effect of convenient disassembly and assembly.

[0012] In the above technical solution, further, the collecting plate is horizontally inserted into the limiting plates on both sides, and the limiting plates are connected to the inner wall of the box.

[0013] In the above technical solution, further, the collecting plate is a metal mesh plate, and the aperture thereof is smaller than the diameter of the water mist generated by the atomizing generator.

[0014] In this technical solution, under the action of wind force of the mist-dispelling assembly, the water mist collides with the collecting plate and is deposited, and then merges with other deposited water mist. When the merged paper reaches a certain size, it drips from the net due to gravity.

[0015] In the above technical scheme, further, it also includes a liquid collecting tank, which is arranged on the outer side of the box and connected to the box. The liquid collecting tank is connected to a drainage pipe, an inclined drainage plate is arranged in the box corresponding to the liquid collecting tank, and a filter plate is arranged at the connection between the liquid collecting tank and the box.

[0016] In the above technical solution, further, the filter plate is inserted between the "L" fixing plates on both sides of the through opening.

[0017] In the present technical solution, the filter plate is used to filter impurities, so that the water collected in the liquid collecting tank can be directly reused, and the filter plate is inserted in the liquid collecting tank for easy replacement and cleaning.

[0018] In the above technical solution, further, a door body is rotatably provided on a side wall on one side in the length direction of the box body, and an observation window is provided on the door body.

[0019] In the present technical solution, the upper part of the door body is hinged to the box body, so the door body can be opened relatively conveniently to inspect and repair the internal devices, and the internal working conditions can also be observed through the observation window.

[0020] The beneficial effects of the utility model are:

[0021] 1. When the paper sheet passes through the box, the atomizing component sprays atomized water to rehumidify the paper sheet. When the humidity sensor senses that the humidity in the box exceeds the preset value, the mist dispelling component pushes the water mist inside the box downward to contact the collecting plate. The water mist is further deposited on the collecting plate and merged until it drips down from the collecting plate due to gravity, thereby controlling the humidity in the box and ensuring uniform rehumidification of the paper sheet.

[0022] 2. The atomization box extends along the paper sheet conveying direction, and the mounting holes are equidistantly arranged at the bottom of the atomization box. Depending on the rehumidification requirements, the atomization generator or the blocking block can be threadedly arranged in the mounting hole, which can also achieve the effect of convenient disassembly and assembly;

[0023] 3. A filter plate is provided at the connection point between the liquid collecting tank and the box body. The filter plate is used to filter impurities so that the water collected in the liquid collecting tank can be directly reused. The filter plate is inserted in the liquid collecting tank for easy replacement and cleaning.

[0024] 4. The upper part of the door is hinged to the box body, so it is easy to open the door to inspect and repair the internal devices, and the internal working conditions can also be observed through the observation window. BRIEF DESCRIPTION OF THE DRAWINGS
