[0028] The longitudinal cutting assembly comprises a longitudinal cutting shaft 19 rotatably installed between the two longitudinal cutting frames 4, a cutting motor 18 is installed on one side of the longitudinal cutting frame 4, the rotating shaft of the cutting motor 18 is connected to the longitudinal cutting shaft 19, a plurality of longitudinal cutting knives 20 are installed at equal distances on the longitudinal cutting shaft 19, the compression rings 13 on the shaft 12 and the driven shaft 22 are installed at equal distances, and each longitudinal cutting knife 20 is located in the gap between adjacent compression rings 13.

[0029] As the optimization scheme of the utility model, the compression ring 13 on the shaft 12 compresses the fiber desiccant downward on the compression ring 13 of the driven shaft 22, and the fiber desiccant is compressed on both sides of the longitudinal cutting knife 20 at the same time, so that uniform and symmetrical compression force can be applied to the material during cutting, the stress generated during cutting is balanced, and warping is prevented, the transverse cutting knife 16 is arranged in the gap of the compression ring 13, the compression position is as close to the cutting port of the longitudinal cutting knife 20 as possible, the distance between them is reduced, and the shaking of the desiccant is reduced.

[0034] The usage process of this utility model:

[0035] Firstly, as Figure 8 As shown, the fiber desiccant is passed sequentially between the clamping rings 13 on the rotating shaft 12 and the driven rotating shaft 22 in the two longitudinal cutting frames 4, and then passes under the guide shaft 21 to reach the rear drive frame 17. After passing under the clamping rings 13 in the rear drive frame 17 and being clamped, the cutting work can begin.

[0036] The longitudinal cutting blade 20 first cuts the fiber desiccant into multiple strips. Then, the fiber desiccant passes through the guide shaft 21 and adheres to the conveyor belt 2. Driven by the conveyor belt 2, it reaches the transverse cutting blade 16. At this time, the clamping ring 13 in front of the transverse cutting blade 16 presses the desiccant tightly. At the same time, the conveyor belt 2 applies a certain pulling force to pull the desiccant, so that the surface tension of the desiccant between the rear drive frame 17 and the longitudinal cutting frame 4 is stable, and the internal stress of the desiccant is pre-stretched and evenly distributed. The pulling force value can be determined according to the specific properties of the material to prevent the desiccant from rebounding after cutting. Under this pulling force, the release of local stress generated by the material during the cutting process is restricted, thereby reducing warping or deformation caused by stress release after cutting. Then, the telescopic rod 15 is activated to drive the transverse cutting blade 16 to cut the desiccant into blocks, completing the cutting work.
