[0002] Corrugated cardboard is a packaging material made of multi-layered cardboard. It is lightweight, high-strength, and provides excellent cushioning. It typically consists of three or five layers: the outermost and innermost layers are stiffer cardboard, called the linerboard and core paper; the middle layer is corrugated paper with a special corrugated shape, called the corrugated layer. The corrugated structure of the corrugated layer provides additional strength and cushioning, allowing the corrugated cardboard to effectively protect the contents from impacts and compression during transportation and storage. The type of corrugation and the number of layers can be selected according to different packaging needs to accommodate goods of varying weights and sizes. Furthermore, corrugated cardboard has excellent environmental characteristics because it is made from renewable paper materials, making it recyclable and reducing its environmental impact.

[0003] In the production process of corrugated cardboard, the face paper is usually pressed onto the surface of the core paper by hot pressing, which requires gluing and hot pressing equipment. With the diversification of market demand for corrugated cardboard, companies need to produce cardboard with different layers according to the specific requirements of customers to meet the needs of different customers. For this reason, we have proposed a gluing and hot pressing equipment for corrugated cardboard production. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-3 The figure shows a preferred embodiment of the present invention, a gluing and hot pressing bonding device for corrugated cardboard production, including a main body 1. An inner core support plate 2 is provided in the middle of one side of the inner wall of the main body 1. A movable frame 3 and a fixed frame 4 are respectively provided on the upper and lower sides of the inner core support plate 2. Both the movable frame 3 and the fixed frame 4 include a tension roller 5, a glue coating roller 6, a pressure plate 7, a push roller 8, and a connecting frame 9. The tension roller 5, the glue coating roller 6, the pressure plate 7, and the push roller 8 are all arranged inside the two connecting frames 9. The difference between the movable frame 3 and the fixed frame 4 is that the connecting frame 9 corresponding to the movable frame 3 is vertically movably connected to the upper side of the inner core support plate 2.

[0020] Specifically, two glue tanks 10 are provided on the outside of the main body 1 of the equipment. The two glue tanks 10 are fixedly installed at one end of the connecting frame 9 corresponding to the movable frame 3 and the fixed frame 4, respectively. One end of each glue tank 10 passes through the connecting frame 9 and is connected to the inside of the coating roller 6. The glue tank 10 stores glue liquid, and the glue liquid is periodically replenished into the coating roller 6 under the control of the internal pump.

[0021] Two push motors 11 are installed on the outside of the main body 1. The two push motors 11 are fixedly installed at one end of the connecting frame 9 corresponding to the movable frame 3 and the fixed frame 4, respectively. The movable ends of the push motors 11 pass through the connecting frame 9 and are fixedly connected to the axis of the push roller 8. The push motors 11 can control the rotation of the push roller 8. The surface of the push roller 8 is provided with a rough wear-resistant layer for pushing the corrugated cardboard formed after hot pressing to move.

[0022] To control the height of the movable frame 3, a screw 12 is rotatably connected to the outside of the main body 1 of the equipment. One end of the screw 12 is threadedly connected to one end of the connecting frame 9 corresponding to the movable frame 3. The top of the screw 12 is fixedly connected to the movable end of the lifting motor 13, which is fixedly installed on the top of the main body 1 of the equipment. After the lifting motor 13 is started, it controls the screw 12 to rotate, and then controls the height of the entire movable frame 3 to change through the connecting frame 9 corresponding to the movable frame 3.

[0023] It should be noted that the outer wall of the main body 1 of the equipment has several openings, and the positions of these openings are matched with the positions of the connecting frame 9, the glue tank 10, the push motor 11, and the screw 12 corresponding to the movable frame 3, so that the connection between the connecting frame 9 and the glue tank 10, the push motor 11, and the screw 12 will not be blocked by the main body 1 of the equipment as the movable frame 3 moves.

[0024] It is understandable that the glue-applying roller 6 includes a sponge layer and a glue-draining layer from the outside to the inside. The glue-draining layer has evenly distributed holes on its surface to allow the glue to pass through so that the sponge layer can absorb it.

[0025] It should be added that each glue tank 10 is equipped with a pump to periodically deliver glue to the coating roller 6 so as to bond the face paper and the core paper.

[0026] In this embodiment, it should also be noted that the bottom height of the pressing plate 7 is flush with the bottom height of the push roller 8, and the surface is a smooth surface, which facilitates the movement of the assembled corrugated cardboard. An electric heating rod is provided inside the pressing plate 7 to raise the surface temperature of the pressing plate 7, so as to facilitate the bonding of the face paper and the core paper.

[0027] Before using the equipment, the two sheets of paper need to be manually passed through the movable frame 3 and the fixed frame 4 and tensioned, and finally extended to the underside of the two push rollers 8. During the process, one end of the core paper passes through the gap between the two pressing plates 7 and is located between the two sheets of paper. When one end of the core paper reaches the middle of the two push rollers 8, the equipment can be started. After the two push motors 11 are started, they control the push rollers 8 to rotate, thereby dragging the sheets of paper and core paper out from one end of the equipment. It should be added that when the equipment is started for the first time, it is necessary to observe whether the un-adhesive sheets of paper and core paper on the front side are separated or fail to move as a whole. If necessary, manual assistance can be provided. This part of the corrugated cardboard needs to be manually glued and bonded later.

[0028] After the equipment is started, as the face paper moves, the glue liquid inside the glue tank 10 flows into the glue coating roller 6 under the action of the pump. The glue coating roller 6 rotates with the movement of the face paper, and finally the sponge layer on the surface of the glue coating roller 6 coats the face paper. When it is necessary to make corrugated cardboard with different layers, the lifting motor 13 needs to be started according to the thickness of the corrugated cardboard after it is made. After the screw 12 rotates, the height of the movable frame 3 is adjusted, and then the distance between the movable frame 3 and the fixed frame 4 and the pressing plate 7 is adjusted to match the thickness of the corrugated cardboard. When making five-layer corrugated board, the combined three-layer corrugated cardboard is first passed through the fixed frame 4 and located on the lower side. The fourth layer of core paper and the fifth layer of face paper are located in the inner core support plate 2 and the movable frame 3 respectively when making three-layer corrugated cardboard. After the push motor 11 is started, the glue is applied by the glue coating roller 6 as the face paper, core paper and cardboard move. After being squeezed and heated by the two pressing plates 7, it is fixed and finally passes out from under the push roller 8. The corrugated cardboard after passing out can be used after being separated in the subsequent process.

[0029] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components.
