Description

Technical Field

[0001] This utility model relates to the field of corrugated paper drying and dehumidification technology, and in particular to a cardboard drying and dehumidification device. Background Technology

[0002] During the production of corrugated cardboard, the finished cardboard, after undergoing a series of processing steps, typically contains a certain amount of moisture. This moisture content can have several adverse effects on the quality of the cardboard. For example, excessive moisture can reduce the cardboard's strength, making it prone to breakage during subsequent handling, storage, and use; it can also cause deformation, affecting dimensional accuracy and preventing packaging products made from the cardboard from meeting expected specifications; furthermore, in high-humidity environments, the cardboard is susceptible to mold growth, reducing its aesthetic appeal and hygiene standards, and severely impacting the product's market image.

[0003] Currently, existing dehumidification methods have many shortcomings. Some traditional dehumidification equipment uses natural ventilation and air drying, which is greatly affected by environmental factors. In rainy weather or areas with high humidity, the dehumidification effect is minimal, and it is time-consuming and extremely inefficient. Some dehumidification equipment that uses heating and drying can reduce the moisture content of cardboard to some extent, but it suffers from uneven heating, which can easily lead to localized overheating of the cardboard. This can alter the physical properties of the cardboard, such as making it brittle and yellowing, thus affecting its quality. Furthermore, some equipment can cause significant damage to the cardboard during the dehumidification process; for example, strong winds can blow off fibers from the cardboard surface, damaging its structure. Therefore, developing a highly efficient, uniform dehumidification device for finished cardboard that minimizes damage is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a paperboard drying and dehumidification device that can efficiently and uniformly remove moisture from finished paperboard while reducing damage to the paperboard and improving paperboard quality and production efficiency.

[0005] To achieve the above objectives, this utility model provides a cardboard drying and dehumidification device, comprising:

[0006] A frame, on which a paper feed platform and a crossbeam support horizontally positioned above the paper feed platform are provided;

[0007] Several first air source components are fixed to the crossbeam support. The first air source components are used to dehumidify and dry the corrugated paper passing through the paper conveying platform in the vertical direction.

[0008] On both sides of the paper feeding platform are width adjustment mechanisms that cooperate with corrugated paper, and a first air outlet is provided on the width adjustment mechanism;

[0009] Several second air source components are fixed on the frame, and the second air source components are connected to the first air outlet to achieve dehumidification and drying of the corrugated paper side wings.

[0010] Furthermore, the paper feeding platform has an overall arch structure, with paper feeding ramps formed on both the front and rear sides. The arch structure of the paper feeding platform allows for adjustment by the width adjustment mechanism, enabling the mechanism to better accommodate the size of the corrugated paper. The paper feeding ramps also ensure smoother entry of the corrugated paper into the feeding platform, preventing paper jams.

[0011] Furthermore, the width adjustment mechanism includes a first slide rail horizontally mounted on the frame, two width supports movably mounted on the first slide rail, a width drive motor fixed to the frame, a first transmission assembly, and an air guide at the end of each width support. The paper feed platform is longitudinally positioned above the first slide rail and higher than the width supports, allowing the width supports to slide through the paper feed platform. The two width supports are respectively positioned on both sides of the paper feed platform. The width drive motor is linked to the first transmission assembly, which in turn is linked to the two width supports, enabling the two width supports to move synchronously in opposite directions. This allows the two width supports to move synchronously in opposite directions left and right on the first slide rail, adjusting according to the width of the corrugated paper. This serves to limit the left and right movement of the corrugated paper while simultaneously cooperating with the second air source assembly to blow air onto both sides of the corrugated paper, allowing airflow to penetrate the gaps between the corrugation peaks and valleys, thereby achieving dehumidification and drying inside the corrugated paper.

[0012] Furthermore, the width support is provided with scale lines for measuring the width of the corrugated paper. This allows the operator to visually know the width of the corrugated paper being fed, facilitating subsequent operations.

[0013] Furthermore, the first transmission assembly includes a first main drive wheel, a first driven wheel, and a first transmission belt. The first transmission belt is looped around the first main drive wheel and the first driven wheel to form a ring. Using the axis connecting the first main drive wheel and the first driven wheel as a reference, the first transmission belt includes a first transmission part positioned above the axis and a second transmission part positioned below the axis. Both width-support members are provided with support connecting parts, which are respectively connected to the first and second transmission parts. When the first transmission belt rotates, the first and second transmission parts move in opposite directions. Therefore, by connecting the two width-support members to the first and second transmission parts respectively, the two width-support members located on both sides of the paper feed platform can move synchronously towards the paper feed platform or synchronously move outward away from the paper feed platform. This allows the two width-support members to simultaneously and synchronously wrap both sides of the corrugated paper as it enters the paper feed platform, enabling the corrugated paper to be placed on the air duct for dehumidification and drying.

[0014] Furthermore, the air guide component includes a first connecting part, a second connecting part, and a first air guide portion. The first connecting part and the second connecting part are arranged perpendicularly to each other. The first connecting part is fixed to the end of the width support component. An air duct is formed between the second connecting part and the width support component. The first air outlet is disposed on the first connecting part and communicates with the air duct. A quick connector is provided on the first air outlet. The first air guide portion is positioned above the air duct and tilted upwards, forming a funnel-shaped inlet with the width support component. A detection sensor is provided on the first air guide portion. The detection sensor can monitor the corrugated paper entering the paper feeding platform in real time, so that when the corrugated paper enters the paper feeding platform, the two width supports can simultaneously and synchronously wrap both sides of the corrugated paper, allowing both sides of the corrugated paper to be placed on the air duct for dehumidification and drying.

[0015] Furthermore, the second air source assembly includes a first blower and a second blower fixed to the frame. The first blower and the second blower are respectively connected to quick connectors on two flap support members through ventilation pipes. The first blower and the second blower can be configured to blow air and draw air in, respectively. In this way, the first blower blows air to form an airflow, which enters the first air outlet and air duct along the ventilation pipe and quick connector. Then, it enters the gap between the crests and valleys of the corrugated cardboard on one side wing of the air duct. Next, the airflow enters the other air duct from the other side wing through the gap of the corrugated cardboard. The second blower performs a suction operation, drawing out the airflow from the other air duct. This forms a continuous circulation to dehumidify and dry the interior of the corrugated cardboard.

[0016] Furthermore, the first air source component includes a fan housing, a fan motor fixed inside the fan housing, and fan blades connected to the fan motor.

[0017] Furthermore, three sets of first air source components are installed on the crossbeam support, and these first air source components are equidistantly arranged above the paper conveying platform. This forms a uniform airflow output, which can effectively dehumidify and dry the surface of the corrugated paper.

[0018] Furthermore, electrical control equipment is installed on the frame beam support to achieve automated control and coordination of the various components.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention features several first air source components mounted on a crossbeam support, enabling vertical airflow onto the corrugated paper on the paper feeding platform to achieve dehumidification and drying of the upper surface of the corrugated paper. Below the paper feeding platform, a width support component that can move synchronously in opposite directions is installed. This width support component automatically adjusts according to the width of the corrugated paper, placing both sides of the corrugated paper within the air duct. A first blower and a second blower are installed within the frame. The first blower (blowing blower) and the second blower (suction blower) work together to blow air from one side of the corrugated cardboard to the other side. The airflow passes through the gaps between the corrugation peaks and valleys of the corrugated cardboard, thereby achieving dehumidification and drying of the cardboard's interior.

[0021] The cardboard dehumidifier is connected to the corrugated cardboard production management system by manual operation. The production management system sends the current production data of corrugated cardboard to the control board of the cardboard dehumidifier. In addition, the detection sensors of the cardboard dehumidifier receive the paper feeding signal, automatically start the fan and automatically adjust the width of the paper feeding platform, so as to realize the automatic dehumidification of corrugated cardboard. This utility model has the characteristics of stable and reliable operation, high efficiency of dehumidification, uniform dehumidification, reduced cardboard damage, and high degree of automation.

[0030] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0033] Please see Figures 1 to 5An embodiment of this utility model provides a cardboard drying and dehumidification device, including a frame 1, a width adjustment mechanism 2, a plurality of first air source components 3, and a second air source component 4 fixed on the frame 1.

[0034] like Figure 1 and Figure 2 As shown, a paper feeding platform 11 and a crossbeam support 12 horizontally arranged above the paper feeding platform 11 are provided on the frame 1. The paper feeding platform 11 is an arch structure, which creates enough space below the paper feeding platform 11 for the movement of the width adjustment mechanism 2. The main body of the paper feeding platform 11 is flat, which facilitates the movement of the corrugated paper 5 on it. Paper feeding ramps 111 are formed on the front and rear sides of the paper feeding platform 11. The paper feeding ramps 111 can facilitate the smooth entry and exit of the corrugated paper 5 and avoid paper jams.

[0035] The first air source component 3 is fixedly connected to the crossbeam support 12. The first air source component 3 includes a fan housing 31, a fan motor 32 fixed inside the fan housing 31, and a fan blade 33 connected to the fan motor 32. The air outlet of the first air source component 3 faces the paper feeding platform 11, thereby realizing the vertical dehumidification and drying of the corrugated paper 5 passing through the paper feeding platform 11. Preferably, three sets of evenly arranged first air source components 3 are provided on the crossbeam support 12, thereby meeting the dehumidification and drying operation of corrugated paper 5 with different widths.

[0036] In this embodiment, two width adjustment mechanisms 2 are provided, which are symmetrically arranged on both sides of the paper feeding platform 11. The width adjustment mechanism 2 includes a first slide rail 21 horizontally mounted on the frame 1, two width support members 22 movably mounted on the first slide rail 21, a width drive motor 23 fixed to the frame 1, a first transmission assembly 24, and an air guide member 25 disposed at the end of the width support member 22. A measuring device for measuring the width of the corrugated paper 5 is provided on the width support member 22. The scale markings 224 are provided on the air guide 25, and the first air outlet 223 is provided on the air guide 25. The paper feed platform 11 is longitudinally arranged above the first slide rail 21 and higher than the width support 22, so that the width support 22 can slide through the paper feed platform 11. The two width support 22 are respectively arranged on both sides of the paper feed platform 11. The width drive motor 23 is linked with the first transmission component 24. The first transmission component 24 is linked with the two width support 22 respectively, so that the two width support 22 move synchronously in opposite directions.

[0037] Preferably, to achieve synchronous and opposite-direction movement of the two flap support members 22, the aforementioned first transmission assembly 24 includes a first main transmission wheel 241, a first driven wheel 242, and a first transmission belt 243. The first transmission belt 243 is sleeved on the first main transmission wheel 241 and the first driven wheel 242 to form a ring. Taking the axis connecting the first main transmission wheel 241 and the first driven wheel 242 as a reference, the first transmission belt 243 includes a first transmission part 2431 located above the axis connecting line and a second transmission part 2432 located below the axis connecting line. Both flap support members 22 are provided with a support connection part 221, and the support connection part 221 of the flap support member 22 is connected to the first transmission part 2431 and the second transmission part 2432 respectively.

[0038] like Figure 4 As shown, the air guide 25 includes a first connecting part 251, a second connecting part 252, and a first air guide part 253. The first connecting part 251 and the second connecting part 252 are arranged perpendicular to each other. The first connecting part 251 is fixed to the end of the door support 22. The second connecting part 252 and the door support 22 form an air duct 222. The first air outlet 223 is provided on the first connecting part 251 and communicates with the air duct 222. A quick connector 43 is provided on the first air outlet 223. The first air guide part 253 is placed above the air duct 222 and tilted upwards, forming a funnel-shaped inlet / outlet with the door support 22, thereby guiding the air volume. A detection sensor 6 is provided on the first air guide part 253.

[0039] The second air source component 4 is connected to the first air outlet 223 to achieve dehumidification and drying of the side wings of the corrugated paper 5. The specific configuration is as follows: Figure 3 and Figure 4 As shown, the second air source assembly 4 includes a first blower 41 and a second blower 42 fixed to the frame 1. The first blower 41 and the second blower 42 are respectively connected to quick connectors 43 on the two flap support members 22 through ventilation pipes 44. The first blower 41 and the second blower 42 can be respectively configured so that one blows air and the other draws air. In this way, the first blower 41 blows air to form an airflow. The airflow enters the first air outlet and the air duct 222 along the ventilation pipe 44 and the quick connector 43, and then enters the gap 51 between the crests and valleys of the corrugated paper 5 on one side wing of the corrugated paper 5 placed in the air duct 222 (e.g., Figure 5As shown in the diagram, the airflow then enters another air duct 222 from the other side through the gap 51 of the corrugated paper 5. The second blower 42 performs suction, drawing the airflow out of the other air duct 222, thus forming a continuous cycle to dehumidify and dry the interior of the corrugated paper 5. It should be noted that in this embodiment, the first blower 41 and the second blower 42 are respectively located on the left and right sides of the frame 1, with the right side blowing air and the left side suction, forming an airflow trajectory from right to left. In other configurations, the positions can be adjusted according to requirements, for example, blowing air on the left and suction on the right, forming an airflow trajectory from left to right. It is only necessary to ensure that the airflow flows between the gaps 51 between the corrugations and troughs of the corrugated paper 5.

[0040] An electrical control device 7 is installed on the crossbeam support 12 of the frame 1 to realize the automated control and coordination of each component.

[0041] Briefly, the working principle of this utility model is as follows: The cardboard dehumidifier is manually connected to the corrugated cardboard production management system. The production management system sends the current production data of the corrugated board to the electrical control device 7 of the cardboard dehumidifier. The production management system then transfers the completed corrugated paper 5 to the paper feeding platform 11. The detection sensor 6 detects the corrugated paper 5 and sends feedback to the electrical control device 7. Based on the data of the corrugated paper 5, the electrical control device 7 controls the start of the width drive motor 23, which drives the two width support members 22 to move synchronously, matching the distance between them to the width of the corrugated paper 5 to be fed in (in some embodiments, this can also be achieved through a detection sensor). The sensor 6 detects the width of the incoming corrugated paper 5 and then controls the movement of the width support 22 to adjust the spacing between the width support 22. When the corrugated paper 5 enters the paper feeding platform 11, the sensor 6 detects the corrugated paper 5, and the electrical control equipment 7 controls the first air source component 3 and the second air source component 4 to work. The first air source component 3 blows air to dehumidify and dry the upper surface of the corrugated paper 5, and the second air source component 4 consists of a first blower 41 and a second blower 42 that blows and sucks air to dehumidify and dry the gaps 51 between the corrugation peaks and valleys of the corrugated paper 5, thus realizing automatic dehumidification of the corrugated paper 5.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
