Description

Technical Field

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

[0002] A dehumidifier for corrugated paper production is a specialized device used to remove excess moisture during the corrugated paper manufacturing process. It typically consists of a housing, an air inlet assembly, a tray, and a control system. In operation, the fan in the air inlet assembly is activated to generate airflow. This airflow passes through a filter plate and enters the housing, carrying away moisture from the surface of the corrugated paper. The moisture is then discharged through the air outlet at the top of the housing, creating an internal airflow circulation. During dehumidification, the angle of the tray can be adjusted as needed. Dehumidifiers for corrugated paper production are widely used on corrugated paper production lines.

[0003] For example, Chinese patent CN219797782U, entitled "A Dehumidifying Device for Corrugated Paper Production," includes a housing, the inner part of which is divided into a front cavity and a rear cavity, which are interconnected. An air inlet assembly is provided in the rear cavity. An openable door cover is provided at the front of the housing, and the door cover has an upward-facing air outlet. Multiple trays are horizontally placed sequentially in the front cavity, with both ends rotatably connected to the housing. The air inlet assembly includes a sidewall welded to the rear cavity and a first fan fixed to the air inlet of the housing. Two... A filter plate is provided between the side walls. Multiple guide plates are arranged vertically and evenly at the connection between the front cavity and the rear cavity. A sliding damper is provided on the side wall, and an adjusting rod threadedly connected to the housing is provided on the damper. Multiple support ribs are arranged sequentially on the upper surface of the support plate along the direction of airflow. Limiting vertical plates are provided at the four corners of the support plate. A through hole is provided between every two support ribs. A worm shaft is provided on the right side of the housing. A worm wheel meshing with the worm shaft is provided on the support plate. A second fan is provided on the air outlet.

[0004] While the aforementioned existing technologies can achieve dehumidification of corrugated paper, in practical use, it is difficult to fix the corrugated paper in place. Usually, the corrugated paper is placed on a pallet and the airflow blows directly onto it, causing the corrugated paper to be blown up by the airflow, thus affecting the dehumidification effect. On the other hand, dust in the air is easily mixed into the airflow. Usually, during dehumidification, dust is mixed into the airflow and enters the dehumidification chamber, causing dust to adhere to the surface of the corrugated paper, thereby reducing the production quality of the corrugated paper. Therefore, it does not meet the current requirements. To address this, we propose a dehumidification device for corrugated paper production. Utility Model Content

[0005] The purpose of this invention is to provide a dehumidification device for corrugated paper production, so as to solve the problems mentioned in the background art, such as the difficulty in fixing corrugated paper and the easy mixing of dust from the air into the airflow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dehumidification device for corrugated paper production, comprising a base, a dehumidification box fixedly mounted on the upper end of the base, five fixed seats fixedly mounted on both sides inside the dehumidification box, the fixed seats being evenly distributed from top to bottom, a sliding groove provided inside the fixed seat, the front end of the sliding groove being an open structure, a snap-fit ​​strip provided inside the sliding groove, the snap-fit ​​strip slidingly engaging with the sliding groove, and one end of the snap-fit ​​strip extending to the outside of the sliding groove, a support plate fixedly mounted between the snap-fit ​​strips, the support plate being a hollow structure, five threaded holes provided on the upper sides of both sides inside the support plate, the threaded holes being evenly distributed, bolts provided inside the threaded holes, the lower ends of the bolts extending into the hollow structure of the support plate, a rubber pad provided at the lower end of the bolts, the rubber pad being rotatably connected to the bolts.

[0007] Preferably, the lower end of the tray is provided with a plurality of ventilation chambers, which are equidistantly distributed and have a through-type structure.

[0008] Preferably, slots are provided on both sides of the interior of the rear side wall of the dehumidification box, and the upper end of the slot is an open structure. Several connecting cavities are provided inside the front and rear ends of the dehumidification box, which are connected to the slot and are equidistantly distributed. A filter plate is provided inside the slot, which slides with the slot, and the interior of the filter plate is a mesh structure.

[0009] Preferably, a fixing plate is fixedly installed at the upper and lower sides of the rear end of the dehumidification box, and a plurality of heating wires are fixedly installed between the fixing plates, with the heating wires being evenly distributed.

[0010] Preferably, a drive motor is fixedly installed above and below the outer rear end of the dehumidification box, the output shaft of the drive motor extends into the interior of the dehumidification box, and a fan blade is fixedly installed outside the output shaft of the drive motor, with the fan blade located at the rear end of the heating wire.

[0011] Preferably, mounting bases are fixedly provided on the upper and lower sides of the front end of the dehumidification box, and a box door is provided between the mounting bases. The box door is rotatably connected to the mounting bases, and an observation window is provided inside the box door, with the observation window corresponding to the position of the tray.

[0012] Preferably, an exhaust pipe is fixedly installed at the center of the upper end of the dehumidification box, and the exhaust pipe is connected to the dehumidification box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can squeeze and fix the redundant sides of the corrugated paper by means of bolts and threaded holes. Before dehumidifying the corrugated paper, the damp corrugated paper is placed on the pallet. Then the operator rotates the bolt so that the bolt moves downward through the threaded hole until the rubber pad at the lower end of the bolt contacts the surface of the corrugated paper. Then the bolt is rotated to squeeze and fix the redundant sides of the corrugated paper by the rubber pad, so as to avoid the corrugated paper being blown up during the dehumidification process, thereby improving the dehumidification effect of the corrugated paper.

[0015] (2) This utility model can intercept dust in the air through the filter plate and slot. When dehumidifying the corrugated paper, the drive motor is turned on, so that the output shaft of the drive motor drives the fan blade to rotate. The rotation of the fan blade accelerates the air to enter the dehumidification box through the connecting cavity. Before the airflow enters the dehumidification box, the airflow passes through the filter plate for filtration, so that the dust mixed in the airflow is intercepted and filtered by the filter plate. At this time, the clean air enters the dehumidification box, thereby improving the production quality of corrugated paper. Until the dehumidification operation of corrugated paper is completed, the operator pulls the filter plate out of the slot and cleans it. Finally, the cleaned filter plate is reinserted into the slot to avoid dust clogging the mesh on the filter plate.

[0016] (3) This utility model can heat the airflow entering the dehumidification box by using a fixing plate and a heating wire. When dehumidifying corrugated paper, the corrugated paper has been fixed on the tray. At this time, when the heating wire is energized, the current flows through the heating wire which has a certain resistance. The heating wire generates a certain amount of heat under the action of the current and transfers the heat to the airflow generated by the fan blade rotation through thermal radiation, thereby raising the temperature of the airflow. The heated airflow blows onto the damp corrugated paper, causing the moisture on its surface to evaporate quickly, thereby improving the dehumidification efficiency of the corrugated paper.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a dehumidification device for corrugated paper production, including a base 1. A dehumidification box 2 is fixedly installed on the upper end of the base 1. Five fixed seats 9 are fixedly installed on both sides inside the dehumidification box 2. The fixed seats 9 are evenly distributed from top to bottom. Mounting seats 4 are fixedly installed on the upper and lower sides of one side of the front end of the dehumidification box 2. A box door 5 is provided between the mounting seats 4. The box door 5 is rotatably connected to the mounting seats 4. An observation window 6 is provided inside the box door 5. The observation window 6 corresponds to the position of the tray 11. An exhaust pipe 3 is fixedly installed at the center of the upper end of the dehumidification box 2. The exhaust pipe 3 is connected to the dehumidification box 2.

[0024] Please see Figure 2 , Figure 3 and Figure 4 The mounting base 9 has a sliding groove 10 inside, with an open front end. A snap-fit ​​strip 12 is installed inside the sliding groove 10, slidingly engaging with it. One end of the snap-fit ​​strip 12 extends to the outside of the sliding groove 10. A support plate 11 is fixedly installed between the snap-fit ​​strips 12. The support plate 11 has a hollow structure. Five threaded holes 21 are provided on the upper sides of both sides of the support plate 11, evenly spaced. Bolts 14 are installed inside the threaded holes 21, with their lower ends extending into the hollow structure of the support plate 11. A rubber pad 15 is installed at the lower end of the bolt 14, rotatably connected to it. Several ventilation chambers 13 are provided at the lower end of the support plate 11, evenly spaced and through-hole, facilitating the fixing of redundant sides of the corrugated paper via the rubber pads 15 and bolts 14.

[0025] Please see Figure 1 and Figure 3The dehumidifier 2 has slots 8 on both sides of the inner side wall of the rear end. The upper end of the slot 8 is open. The dehumidifier 2 has several connecting cavities 19 in the inner front and rear ends of the slot 8. The connecting cavities 19 are connected to the slot 8 and are evenly distributed. The slot 8 has a filter plate 7 inside. The filter plate 7 slides with the slot 8. The filter plate 7 has a mesh structure inside, which facilitates the interception and filtration of dust in the air.

[0026] Please see Figure 2 and Figure 3 The dehumidification chamber 2 has fixed plates 16 at the top and bottom of the rear end, and several heating wires 17 are fixed between the fixed plates 16. The heating wires 17 are evenly distributed. The dehumidification chamber 2 has drive motors 20 at the top and bottom of the rear end, and the output shaft of the drive motor 20 extends into the interior of the dehumidification chamber 2. The output shaft of the drive motor 20 has fan blades 18 fixed outside the output shaft of the drive motor 20. The fan blades 18 are located at the rear end of the heating wires 17 to facilitate the increase of airflow temperature through the heating wires 17.

[0027] Working principle: In use, first place the damp corrugated paper on the tray 11. Then, the operator rotates the bolt 14, causing the bolt 14 to move downwards through the external thread in the threaded hole 21 until the rubber pad 15 at the lower end of the bolt 14 contacts the surface of the corrugated paper. Continue rotating the bolt 14 to compress and fix the excess sides of the corrugated paper with the rubber pad 15. At this time, the drive motor 20 is turned on, causing the output shaft of the drive motor 20 to drive the fan blades 18 to rotate. The rotation of the fan blades 18 accelerates the air to enter the dehumidification chamber 2 through the connecting cavity 19. Before the airflow enters the dehumidification chamber 2, it is filtered by the filter plate 7, which intercepts and filters the dust mixed in the airflow. At this time, the clean air enters the dehumidification chamber 2 and simultaneously powers the heating wire 17. When the current flows through the heating wire 17, which has a certain resistance, the heating wire 17 generates a certain amount of heat under the action of the current. The heat is then transferred to the airflow generated by the rotation of the fan blade 18 through thermal radiation, thereby raising the temperature of the airflow. The heated airflow is then blown onto the damp corrugated paper, causing the moisture on its surface to evaporate quickly.
