Description

Technical Field

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

[0002] Corrugated cardboard is a widely used material in the packaging industry, favored for its excellent cushioning performance, compressive strength, and environmental friendliness. It is typically composed of one or more layers of corrugated core paper sandwiched between two or more layers of sheet paper. It is widely used in the manufacture of various cartons and plays an important role in many fields such as food, electronics, and pharmaceuticals. In the production process of corrugated cardboard, bonding is one of the key processes. After bonding, the cardboard usually contains a certain amount of moisture. If it is not dried in a timely and even manner, problems such as deformation, bubbling, sticking, or reduced strength can easily occur, seriously affecting the quality of subsequent printing, die-cutting, and other processing, and even reducing the performance of the finished product.

[0003] Currently, common drying methods often involve natural air drying. However, these methods generally suffer from problems such as low drying efficiency, high energy consumption, and uneven drying. Especially in high humidity environments, the air contains a lot of dust and impurities. If these impurities are not purified before entering the drying area, they can easily adhere to the surface of the cardboard, causing contamination and affecting the appearance quality and cleanliness of the product.

[0004] Therefore, it is necessary to design a dehumidifying corrugated cardboard drying device to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical solution is as follows: A dehumidifying corrugated cardboard drying device includes a support frame, a motor, a rotating rod, a conveyor belt, a first mounting frame, a first fan, a first heating wire, a filter plate, and a controller. A motor is fixedly connected to the front left side of the support frame, and the output shaft of the motor is connected to a rotating rod. Another rotating rod is rotatably connected to the rear of the support frame. A conveyor belt connects the two rotating rods, and multiple elongated slots for ventilation are evenly distributed on the conveyor belt. A first mounting frame is fixedly connected to the top front side of the support frame, and a first fan is installed inside the first mounting frame. A first heating wire is located in the lower part of the first mounting frame. A filter plate is located between the support frame and the first mounting frame. The first heating wire and the filter plate are located below the first fan. A controller is fixedly connected to the front left side of the support frame, and the controller is electrically connected to the motor, the first fan, and the first heating wire.

[0007] Furthermore, it also includes a second mounting bracket, a second fan, and a ventilation plate. The second mounting bracket is fixedly connected to the rear top of the support bracket. The second fan is installed inside the second mounting bracket. A ventilation plate is provided between the support bracket and the second mounting bracket. The ventilation plate has multiple through holes. The controller is electrically connected to the second fan.

[0008] Furthermore, it also includes a temperature detector and an alarm. The temperature detector is installed on the top wall inside the support frame, and the alarm is fixedly connected to the middle of the side of the first mounting frame that is far apart from each other. The controller is electrically connected to the temperature detector and the alarm respectively.

[0009] Furthermore, it also includes connecting pipes. The front and rear sides of the support frame are connected and connected to the connecting pipes respectively. The upper ends of the two connecting pipes are connected to the interior of the second mounting frame and the first mounting frame respectively. The lower ends of the two connecting pipes are inserted into the lower part of the support frame and located below the conveyor belt. Multiple ventilation holes are evenly opened in the lower part of the two connecting pipes respectively.

[0010] Furthermore, it also includes curtains, with curtains installed on the front, middle and rear sides of the support frame.

[0011] Furthermore, it also includes a loading box and a second heating wire. The loading box is placed on the lower rear side of the support frame, and the four walls of the loading box are respectively provided with the second heating wire. The controller is electrically connected to the second heating wire.

[0012] The beneficial effects are as follows: 1. This utility model generates hot air by cooperating with the first fan and the first heating wire, and the air is purified by the filter plate to achieve clean and efficient drying, avoid contaminating the surface of the cardboard, and improve product quality and equipment service life.

[0013] 2. This utility model uses a second fan to draw in the hot and humid air from the bottom of the drying area and transport it back to the mounting frame through a connecting pipe. The air is then mixed with fresh air, heated, and used for drying again, thus realizing the recycling of hot air. This significantly improves the thermal energy utilization rate, reduces energy consumption, and has outstanding energy-saving and environmental protection effects.

[0014] 3. This utility model achieves temperature monitoring and abnormal alarm by linking a temperature detector and an alarm, preventing damage to corrugated cardboard or overheating of equipment, and improving operational safety and stability.

The motor 2 is mounted on the front left side of the support frame 1 by screws. The output shaft of the motor 2 is connected to a rotating rod 201. Another rotating rod 201 is rotatably connected to the rear of the support frame 1. The conveyor belt 3 is connected between the two rotating rods 201. Multiple long slots for ventilation are evenly opened on the conveyor belt 3. The first mounting frame 4 is mounted on the top front side of the support frame 1 by screws. The first fan 5 is installed inside the first mounting frame 4. The first heating wire 6 is located in the lower part of the first mounting frame 4. The filter plate 7 is located between the support frame 1 and the first mounting frame 4. The first heating wire 6 and the filter plate 7 are located below the first fan 5. The controller 8 is mounted on the front left side of the support frame 1 by screws. The controller 8 is electrically connected to the motor 2, the first fan 5, and the first heating wire 6.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it also includes a second mounting bracket 401, a second fan 9 and a ventilation plate 10. The second mounting bracket 401 is installed on the rear top side of the support bracket 1 by screws. The second fan 9 is installed inside the second mounting bracket 401. A ventilation plate 10 is provided between the support bracket 1 and the second mounting bracket 401. The ventilation plate 10 has multiple through holes. The controller 8 is electrically connected to the second fan 9.

[0026] like Figure 3 and Figure 6 As shown, it also includes a temperature detector 11 and an alarm 12. The temperature detector 11 is installed on the top wall inside the support frame 1. The alarm 12 is installed in the middle of the side of the first mounting frame 4 that is far apart from each other by screws. The controller 8 is electrically connected to the temperature detector 11 and the alarm 12 respectively.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, it also includes connecting pipes 13. The front and rear sides of the support frame 1 are respectively connected and connected to the connecting pipes 13. The upper ends of the two connecting pipes 13 are respectively connected to the interior of the second mounting frame 401 and the first mounting frame 4. The lower ends of the two connecting pipes 13 are respectively inserted into the lower part of the support frame 1 and located below the conveyor belt 3. The lower part of the two connecting pipes 13 is evenly provided with multiple ventilation holes 14.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes a curtain 15, a loading box 16, and a second heating wire 17. The curtain 15 is installed on the front, middle and rear sides of the support frame 1, and the loading box 16 is placed on the lower rear side of the support frame 1. The four walls of the loading box 16 are respectively provided with the second heating wire 17. The controller 8 is electrically connected to the second heating wire 17.

[0029] When dehumidifying and drying corrugated cardboard, first, place the device on a stable working surface, ensuring the support frame 1 is secure. Then, connect the power supply, and the controller 8 enters the working state. The operator sets parameters such as the drying temperature, the operating speed of the first fan 5 and the second fan 9, and the operating speed of the conveyor belt 3 through the controller 8. After setting, the controller 8 automatically starts the motor 2. The output shaft of the motor 2 drives one rotating rod 201 to rotate, which in turn drives another rotating rod 201 to rotate synchronously through the conveyor belt 3, ensuring the smooth operation of the conveyor belt 3 and achieving continuous conveying of the corrugated cardboard. While the conveyor belt 3 is running, the first fan 5 starts, drawing in external air and filtering it through the filter plate 7 to remove dust and impurities, ensuring the air entering the drying area is clean. The filtered air enters the first mounting frame 4 and is converted into hot air under the heating action of the first heating wire 6, blowing downwards onto the corrugated cardboard on the conveyor belt 3. The conveyor belt 3 has multiple evenly spaced long slots for ventilation, allowing the hot air to... The hot air passes through the cardboard from below, enhancing the drying effect and improving the efficiency of moisture evaporation. To improve the utilization rate of hot air, during the drying process, after the hot air blown downward by the first fan 5 penetrates the cardboard, some of the hot and humid air will accumulate at the bottom of the support frame 1. At this time, the second fan 9 is started synchronously under the control of the controller 8. Its operation generates negative pressure in the second mounting frame 401. This negative pressure is transmitted to the ventilation hole 14 at the bottom of the support frame 1 through the connecting pipe 13, thereby continuously drawing in the accumulated hot and humid air. The drawn-in hot and humid air is blown into the second mounting frame 401 by the second fan 9 through the connecting pipe 13, and mixed with the fresh air supplemented by the ventilation plate 10. The mixed air is then blown out by the second fan 9 to participate in the drying of the rear section of the cardboard, thereby realizing the recycling of hot air, greatly improving the utilization efficiency of heat energy, and reducing energy consumption. During the drying process, the curtain 15 effectively reduces the leakage of hot air from the drying area, forming a relatively closed drying space, which helps to maintain temperature stability and improve the utilization rate of heat energy.

[0030] During the drying process, the temperature detector 11 monitors the temperature changes in the drying area in real time and feeds the data back to the controller 8. When an abnormal temperature rise is detected, the controller 8 automatically triggers the alarm 12 to sound an alarm, reminding the operator to handle the situation promptly and prevent the corrugated cardboard from being damaged by high temperature or the equipment from malfunctioning. To prevent hot air leakage and improve drying efficiency, curtains 15 are installed on the front, middle, and rear sides of the support frame 1 to form a relatively enclosed drying space and maintain a stable temperature inside the box. After drying, the corrugated cardboard is conveyed to the rear end by the conveyor belt 3 and removed by the operator. The lower rear side of the support frame 1 is then placed... There is a loading bin 16 for storing dried corrugated cardboard. The four walls of the loading bin 16 are equipped with second heating wires 17, which can keep the cardboard warm or further dry it after drying, preventing the corrugated cardboard from becoming damp due to excessive ambient humidity during storage, thus improving the overall energy efficiency and practicality of the equipment. After the drying operation is completed, the operator turns off the controller 8, and then turns off the motor 2, the first fan 5, the second fan 9, the first heating wire 6, and the second heating wire 17 in sequence. After the equipment cools down, the dust and paper scraps on the conveyor belt 3, the filter plate 7, and the curtain 15 are cleaned to ensure the equipment is clean and ready for the next use.
