[0027] Reference Figures 1 to 3 The corrugated cardboard production line of the present invention is described in the following embodiments:

[0028] A corrugated board production line includes: a face paper laminating device 100, a tile laminating machine 300 and a core paper unwinding machine 500.

[0029] The face paper laminating device 100, the tile mounting machine 300, and the core paper unwinding machine 500 are arranged in a sequential arrangement along the front-to-back direction. The face paper hot cylinder machine 200 and the core paper hot cylinder machine 400 are respectively provided on the front and rear sides of the tile mounting machine 300. The face paper hot cylinder machine 200 is located between the face paper laminating device 100 and the tile mounting machine 300. The core paper hot cylinder machine 400 is located between the tile mounting machine 300 and the core paper unwinding machine 500.

[0030] The facial tissue laminating device 100 includes a facial tissue unwinder 110 and a laminating machine 120. The facial tissue unwinder 110 is used to unwind facial tissue rolls, and the laminating machine 120 is used to laminat e facial tissue.

[0031] In actual use, after the face paper of the corrugated paper is unwound from the face paper unwinding machine 110, it is laminated by the laminating machine 120, preheated by the face paper hot cylinder machine 200, and then transported to the tile mounting machine 300. At the same time, after the core paper is unwound from the core paper unwinding machine 500, it can be preheated by the core paper hot cylinder machine 400, and laminated and formed with the face paper in the tile mounting machine 300 to realize the production of corrugated paper, avoid the situation of laminating the corrugated paper after forming, and reduce the production difficulty and cost requirements.

[0032] The corrugated paper laminating machine 300 is used for forming corrugated paper and includes a paper feed mechanism, a laminating machine 300 mechanism, and a paper pressing mechanism. The paper feed mechanism is responsible for feeding paper into the device, the laminating machine 300 mechanism is responsible for pasting the face paper and the core paper together, and the paper pressing mechanism is used to flatten the pasted paper to ensure a secure and smooth paste.

[0033] The face paper heating cylinder machine 200 and the core paper heating cylinder machine 400 are used to preheat the face paper and core paper of the corrugated paper, respectively, so that the face paper and core paper can better meet production requirements when entering the subsequent laminating and forming process, thereby improving production efficiency and product quality. The heating cylinder machine is an important equipment in papermaking machinery. The heating cylinder machine generally includes a preheating cylinder, which uses the high temperature surface of the preheating cylinder to preheat the face paper. When the face paper enters the preheating cylinder, the high temperature surface of the preheating cylinder quickly transfers heat to the face paper, causing the temperature of the face paper to rise rapidly. At the same time, the rotation of the preheating cylinder ensures that the face paper is evenly heated on the surface of the preheating cylinder, thereby achieving the purpose of preheating.

[0034] The facial tissue unwinder 110 is located between the laminating machine 120 and the facial tissue heating cylinder machine 200. In this embodiment, the facial tissue heating cylinder machine 200 and the tile mounting machine 300 are located behind the facial tissue unwinder 110, while the laminating machine 120 is located in front of the facial tissue unwinder 110. The facial tissue unwinder 110, facial tissue heating cylinder machine 200, and tile mounting machine 300 are arranged sequentially. When lamination is not required, the corrugated paper can be directly transported from the facial tissue unwinder 110 to the facial tissue heating cylinder machine 200 for preheating. Furthermore, the laminating machine 120 is located in front of the facial tissue unwinder 110, making it easier to convert production lines without laminating capabilities into the corrugated cardboard production line of this utility model.

[0035] To allow laminated tissue paper to pass through the tissue paper unwinder 110 and be transported to the tissue paper hot cylinder machine 200 and tile mounting machine 300, a tissue paper bridge 710 is installed above the tissue paper unwinder 110. Two paper feed rollers 711 are installed on the paper bridge 710. Both rollers 711 extend axially in the left-right direction. The paper is located above the front and rear ends of the tissue paper unwinder 110. After lamination by the laminator 120, the tissue paper can be sequentially wound around the two paper feed rollers 711, allowing the paper route to pass through the tissue paper unwinder 110.

[0036] The corrugated cardboard production line of this embodiment also includes a corrugated paper bridge 720. The bridge 720 is located above the tile laminating machine 300 and the core paper unwinder 500. The structure of the bridge 720 can be similar to that of the aforementioned face paper bridge 710. Rollers at the front and rear ends of the bridge 720 restrict the path of the formed corrugated paper. Furthermore, if the front-to-back dimensions of the bridge 720 and face paper bridge 710 are relatively large, multiple paper support rollers can be provided to support the corrugated paper or face paper within them.

[0037] The corrugated cardboard production line of the present invention also includes a paper cutter 600. The paper cutter 600 is used to cut and divide the corrugated paper into sheets of specific dimensions. In this embodiment, the paper cutter 600 is located behind the core paper unwinder 500, which is positioned between the paper cutter 600 and the tile laminating machine 300. The front and rear ends of the tile laminating machine 300 and the paper cutter 600 are respectively positioned above the tile laminating machine 300 and the paper cutter 600. The laminated and formed corrugated paper is transported along the paper cutter 720 to the paper cutter 600 for cutting.

[0038] In this embodiment, there is one core paper unwinder 500. The tile laminating machine 300 laminates a single layer of core paper with the face paper to form a single layer of corrugated paper. In other embodiments, when multi-layer corrugated paper is required, the number of core paper unwinders 500 may be multiple. Multiple core paper unwinders 500 are arranged between the tile laminating machine 300 and the paper cutter 600. The core paper of the multiple core paper unwinders 500 can be laminated with the face paper by the tile laminating machine 300 to form multiple layers of corrugated paper.

[0039] In a further embodiment, a paper storage rack and a deviation correction mechanism can be provided between the tile mounting machine 300 and the paper cutter 600. The paper storage rack can store and release corrugated paper between the tile mounting machine 300 and the paper cutter 600, so that the paper cutter 600 can better connect with the tile mounting machine 300 and avoid downtime and waiting.

[0040] The corrugated cardboard production line of the present invention also includes an upper platform 700. The upper platform 700 is mounted above the face paper unwinder 110, the face paper hot cylinder machine 200, the tile laminating machine 300, the core paper hot cylinder machine 400, and the core paper unwinder 500. The face paper bridge 710 and the tile paper bridge 720 are located at the front and rear of the upper platform 700, respectively.

[0041] The upper platform 700 can provide an installation base for the facial tissue paper bridge 710 and the corrugated paper bridge 720, so that they can be suspended above the corrugated board production line. A plurality of pillars extending up and down are provided on the lower side of the upper platform 700. The pillars support and support the upper platform 700. The upper platform 700 can be used to conveniently inspect the facial tissue paper and corrugated paper in the facial tissue paper bridge 710 and the corrugated paper bridge 720, thereby facilitating monitoring of the production quality of the corrugated paper. In a further embodiment, handrails 730 extending forward and backward are provided on both the left and right sides of the upper platform 700. The handrails 730 provide protection for the workers on the upper platform 700, thereby improving safety.

[0042] In this embodiment, a debugging platform 800 is located between the tissue paper hot-cylinder machine 200 and the tile mounting machine 300. A standing surface is provided at the top of the debugging platform 800. A paper feed space extending from front to back is provided below the standing surface. The tissue paper hot-cylinder machine 200 is equipped with a tissue paper discharge roller 210, while the tile mounting machine 300 is equipped with a tissue paper feed roller 310. The tissue paper discharge roller 210 and the tissue paper feed roller 310 are located on the front and rear sides of the debugging platform 800, respectively.

[0043] The staff can stand on the debugging platform 800 to perform maintenance and debugging on the tile mounting machine 300. After the laminated facial paper is preheated in the facial paper heating cylinder machine 200, it passes through the facial paper discharge roller 210 and the facial paper feed roller 310 in sequence, allowing the facial paper to pass through the paper feeding space to avoid obstruction.

[0044] In this embodiment, the face paper unwinder 110 and the core paper unwinder 500 are each provided with two unwinding rollers. The face paper unwinder 110 can alternately unwind through the two unwinding rollers, thereby achieving roll change without stopping the machine and avoiding waste caused by waiting.
