[0034] The pressing plate 5 is located between the lifting cylinder 4 and the base 1 , and the backing paper to be cut extends between the pressing plate 5 and the base 1 .

[0035] The base 1 is used for fixing the mounting bracket 2, the crossbeam 3, the lifting cylinder 4, the pressing plate 5, the roller mechanism 6 and the guide cylinder 7, so as to facilitate the cutting of the bottom cover paper to be cut on the paper cutting device, realize automatic paper covering and reduce labor intensity.

[0036] It should be noted that, since the paper cutting device of the paper laminating machine of the present invention can realize automatic paper cutting, the base paper to be cut can be set as a roll of paper, and the base paper can be transported to the corresponding position by the paper feeding mechanism, and cut according to actual needs. There is no need to splice multiple base papers, thereby ensuring uniform paper covering and further ensuring the quality of the fired partition board.

[0037] The mounting bracket 2 is fixed on the base 1, and is used to fix and install the crossbeam 3. The mounting bracket 2 is located at both ends of the base 1, and the distance between the mounting brackets 2 located at both ends of the base 1 is greater than the width of the backing paper to be cut, so as to ensure that the backing paper to be cut can be smoothly fed between the base 1 and the crossbeam 3 for cutting.

[0038] The crossbeam 3 is mounted on the mounting bracket 2, and is used to fix the lifting cylinder 4 and the pressing plate 5, so that the pressing plate 5 can be lifted and lowered under the action of the lifting cylinder 4, thereby achieving the function of pressing or loosening the backing paper to be cut. The crossbeam 3 is raised to a certain height by the mounting bracket 2, and a gap is formed between the crossbeam 3 and the base 1, so that the backing paper to be cut can be fed between the base and the crossbeam 3 for cutting.

[0039] The crossbeam 3 bears the weight of the lifting cylinder 4 and the pressure plate 5, so it is made of a metal material with high hardness and strong pressure-bearing capacity. In this embodiment, the crossbeam 3 is made of an aluminum profile, and its two ends are respectively fixed to the mounting brackets 2 at the two ends of the base 1.

[0040] The lifting cylinder 4 is fixed on the crossbeam 3, and is used to drive the pressing plate 5 to move up and down, so that the pressing plate 5 can relax or press the backing paper to be cut. In order to keep the pressing plate 5 able to be lifted and lowered smoothly and ensure that the pressure on the pressing plate 5 is uniform, the number of the lifting cylinders 4 is at least two, and at least two lifting cylinders 4 synchronously drive the pressing plate 5 to lift and lower, so as to ensure that the pressure on the pressing plate 5 is uniform.

[0041] In order to achieve a fixed connection between the lifting cylinder 4 and the cross beam 3, a lifting cylinder mounting plate 8 is also included.
