Description

Technical Field

[0002] Corrugated paper is a multi-layered paper material, consisting of at least one layer of corrugated core paper bonded to one or more layers of flat paper using adhesives. Its unique structure gives it excellent cushioning properties and high strength. In the packaging industry, corrugated paper is widely used to make various packaging boxes and cartons. With its excellent compression resistance and shock absorption, corrugated paper can effectively protect the contents from external impacts during transportation and storage, reducing the risk of product damage and becoming an indispensable material in modern logistics packaging.

[0003] Hot-press laminating equipment is a mechanical device that tightly bonds two or more materials together by applying a certain temperature and pressure. In the corrugated paper production process, hot-press laminating equipment plays a key role, enabling the corrugated core paper, face paper, and liner paper to melt rapidly and distribute evenly under high temperature and high pressure, thereby achieving a firm and stable bond between the layers of paper and ensuring the quality and performance of the finished corrugated paper.

[0004] Current hot-pressing laminating equipment uses a pressing plate installed on top of the corrugated paper to press it down. During the hot-pressing process, uneven pressure on the corrugated paper can result in some areas not being pressed effectively, affecting the production quality. Existing technology aims to improve product quality by rationally distributing the pressure points of the pressing plate and controlling the temperature. However, in actual use, after the pressing plate completes one press and continues pressing on the next section, some areas may require secondary pressing or some areas may not be pressed, leading to inconsistencies in the production quality of the corrugated paper.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a corrugated paper hot-pressing bonding device. A base 1 serves as the supporting foundation for the entire device. The same outer shell 6 is fixedly connected to the front and rear sides of the base 1. The outer shell 6 provides protection, preventing external debris from entering the device and affecting its operation, while also protecting internal components. Working slots 3 are provided on both the left and right sides of the outer shell 6, providing space for the device's working area and facilitating the loading and unloading of corrugated paper and related operations. Horizontal plates 4 are fixedly connected to the front and rear sides of the interior of the working slots 3, supporting the conveyor belt 5 and ensuring its stable operation. The same conveyor belt 5 is fixedly connected to adjacent sides of the two horizontal plates 4, transporting the corrugated paper smoothly to the hot-pressing bonding area and subsequent cooling area. Telescopic rods 7 are fixedly connected to the front and rear ends of the inner top of the working slots 3. The telescopic rods 7 can flexibly adjust the height of the insulation shell 8 according to work requirements to achieve different degrees of hot-pressing of the corrugated paper. The other ends of the two telescopic rods 7 are fixedly connected to... The base 1 is fixedly connected to the same heat-insulating shell 8, which plays a good role in heat preservation, reduces heat loss, and ensures the temperature stability of the hot-pressing area. The bottom of the heat-insulating shell 8 is provided with a heat-insulating groove 9, which provides installation space for the hollow roller 10 and further enhances the heat preservation effect. The hollow roller 10 is rotatably connected inside the heat-insulating groove 9. During the hot-pressing process, the hollow roller 10 applies uniform pressure to the corrugated paper by rolling, ensuring the hot-pressing bonding effect. The inner wall of the hollow roller 10 is fixedly connected to a heating tube 11. When the heating tube 11 is energized, it generates heat, which raises the temperature of the hollow roller 10 and provides the heat required for the hot-pressing bonding of the corrugated paper. A blower mechanism 2 is set on the right side of the base 1. The blower mechanism 2 is used to quickly cool down the hot-pressed corrugated paper. A switch 12 is fixedly connected to the front of the base 1, which is electrically connected to the conveyor belt 5 and the motor 203 respectively. The operator can conveniently control the start and stop of the conveyor belt 5 and the operation of the motor 203 through the switch 12, thereby regulating the working status of the equipment.

[0033] Specifically, the corrugated paper to be heat-pressed is first placed on the conveyor belt 5 inside the working grooves 3 on the left and right sides of the outer shell 6 on the top of the base 1. When the equipment is started, the conveyor belt 5 starts to operate, moving the corrugated paper towards the heat-pressing area. At this time, the telescopic rod 7 starts to work, pushing the insulation shell 8 connected below downwards, so that the hollow roller 10 in the insulation groove 9 at the bottom of the insulation shell 8 gradually approaches the corrugated paper. The heating tube 11 heats up after being powered on, heating the hollow roller 10. Due to the insulation effect of the insulation shell 8 and the insulation groove 9, heat loss can be effectively reduced, ensuring that the hollow roller 10 is maintained at a suitable high temperature. As the telescopic rod 7 descends further, the high-temperature hollow roller 10 contacts the corrugated paper and applies pressure to it, realizing the heat-pressing of the corrugated paper. During the bonding process, the conveyor belt 5 continuously and slowly transports the corrugated paper to ensure the continuity of the heat-pressing and to ensure that each bonding area is subjected to uniform heat pressure. By operating the switch 12, the operator can easily control the start and stop of the conveyor belt 5, thereby controlling the conveying process of the corrugated paper.

[0034] Reference Figure 1 and Figure 5The blower mechanism 2 includes a support frame 201 and a transmission belt 207. The support frame 201 serves as the support structure for the entire blower mechanism 2. Its top is fixedly connected to the bottom right side of two horizontal plates 4, providing a stable foundation for the installation of subsequent components. Vertical plates 202 are fixedly connected to the front and rear sides of the top of the support frame 201. The vertical plates 202 are used to install and support components such as the motor 203 and rotating rods, ensuring their stability during operation. The motor 203 is fixedly connected to the upper middle part of the front left end of the front vertical plate 202. The motor 203 serves as a power source, providing power for the operation of the blower mechanism 2. The output end of the motor 203 passes through the front vertical plate 202 and is fixedly connected to a rotating rod 204, transmitting the power of the motor 203 to the rotating rod 204 and causing it to rotate. A rotating rod 205 is rotatably connected to the right end of the adjacent side of the two vertical plates 202. The rotating rod 205 works in conjunction with the rotating rod 204 to realize the operation of the blower mechanism 2. The rear ends of both rods 205 penetrate the rear upright plate 202, allowing the rear ends of the two rotating rods to be fitted with rotating wheels 206 and ensuring smooth rotation. The rear ends of both rotating rod 204 and rotating rod 205 are fixedly connected to rotating wheels 206. Power transmission between rotating rod 204 and rotating rod 205 is achieved through a transmission belt 207. The outer walls of the two rotating wheels 206 are connected by the transmission belt 207, ensuring that rotating rod 204 can synchronously drive rotating rod 205 when rotating. Rotating rod 204 and rotating rod 205 are both fixedly connected to the outer walls of rotating plates 208. The rotating plates 208 rotate with the rotation of the rotating rods, providing an installation position for the fan 209 and driving the fan 209 to rotate and adjust the angle. The bottom front and rear sides of the two rotating plates 208 are fixedly connected to the fan 209 to cool the hot-pressed corrugated paper. The middle and lower parts of the adjacent side of the two vertical plates 202 are fixedly connected to the side of the corresponding horizontal plate 4, which further enhances the stability of the vertical plates 202.

[0035] Specifically, after the motor 203 starts, it outputs power, which drives the first rotating rod 204 to rotate. When the first rotating rod 204 rotates, the wheel 206 on it rotates accordingly. Through the transmission belt 207, the wheel 206 at the rear end of the second rotating rod 205 rotates synchronously, causing the second rotating rod 205 to start rotating as well. At this time, the rotating plate 208 rotates along with the first rotating rod 204 and the second rotating rod 205 to adjust the angle of the fan 209 and increase the air blowing area of ​​the fan 209. The vertical plate 202 and the horizontal plate 4 provide a stable installation support for the blower mechanism 2.

[0036] Reference Figure 1 , Figure 3 and Figure 4An observation window 13 is fixedly connected to the front of the outer casing 6. The observation window 13 provides the operator with a window to observe the internal working conditions of the equipment and to view the equipment's operating status in real time. A protective shell 14 is fixedly connected to the outer wall of the observation window 13 to protect it from damage caused by external impact. Guide plates 15 are fixedly connected to the top of both horizontal plates 4. The guide plates 15 guide the conveying direction of the corrugated paper and ensure its smooth movement on the conveyor belt 5. Guide grooves 16 are opened on adjacent sides of the two guide plates 15. The guide grooves 16 further limit the conveying path of the corrugated paper and prevent the paper from deviating. The base 1 has triangular fixing plates 17 fixedly connected to the front and rear ends of both sides. The triangular fixing plates 17 utilize the stability of triangles to enhance the connection strength between the base 1 and the horizontal plate 4. The tops of multiple triangular fixing plates 17 are fixedly connected to the bottom of the corresponding horizontal plate 4, providing stable support for the horizontal plate 4 and ensuring its stability when carrying items. The front and rear sides of the insulation shell 8 are fixedly connected to sliders 18. The sliders 18 cooperate with the sliding grooves 19 to provide guidance for the movement of the insulation shell 8. The front and rear sides of the working groove 3 are provided with sliding grooves 19, which work together with the sliders 18 to enable the insulation shell 8 to move up and down smoothly.

[0037] Specifically, during the corrugated paper hot-pressing process, the operator can clearly see the paper conveying status on the conveyor belt 5 and the working status of the hot-pressing area through the observation window 13. When the conveyor belt 5 moves the corrugated paper, the guide plate 15 and the guide groove 16 can restrict the direction of paper movement, so that the corrugated paper is smoothly conveyed along the predetermined route. The triangular fixing plate 17 enhances the connection strength between the horizontal plate 4 and the base 1, providing additional support for the horizontal plate 4. When the telescopic rod 7 pushes the insulation shell 8 up and down, the slider 18 slides in the slide groove 19, providing guidance for the movement of the insulation shell 8 and ensuring that the insulation shell 8 can rise and fall smoothly.

[0038] Working principle: When using this corrugated paper hot pressing and bonding equipment, the corrugated paper to be hot pressed and bonded is first placed on the conveyor belt 5 in the working grooves 3 on the left and right sides of the outer shell 6 on the top of the base 1. When the equipment is started, the conveyor belt 5 starts to operate, driving the corrugated paper towards the hot pressing and bonding area. At this time, the telescopic rod 7 starts to work, pushing the insulation shell 8 connected below downwards, so that the hollow roller 10 in the insulation groove 9 at the bottom of the insulation shell 8 gradually approaches the corrugated paper. The heating tube 11 heats up after being powered on, heating the hollow roller 10. Due to the insulation effect of the insulation shell 8 and the insulation groove 9, heat loss can be effectively reduced, ensuring that the hollow roller 10 is maintained at a suitable high temperature. As the telescopic rod 7 descends further, the high temperature hollow roller 10 contacts the corrugated paper and applies pressure to it, realizing the hot pressing and bonding of the corrugated paper. During the bonding process, the conveyor belt 5 continuously and slowly transports the corrugated paper to ensure the continuity of the hot pressing and bonding, and to ensure that each bonding area is subjected to uniform hot pressing.

[0039] After the motor 203 starts, it outputs power, which drives the first rotating rod 204 to rotate. When the first rotating rod 204 rotates, the wheel 206 on it rotates accordingly. Through the transmission belt 207, the wheel 206 at the rear end of the second rotating rod 205 rotates synchronously, causing the second rotating rod 205 to start rotating as well. At this time, the rotating plate 208 rotates along with the rotating rods 204 and 205 to adjust the angle of the fan 209 and increase the air blowing area of ​​the fan 209.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
