The transmission gear set 32 is located on the movable frame 20 and is driven by the rotating motor 31. The rack 33 has a retaining tooth 331 on its side for meshing with the transmission gear set 32. The rotating motor 31 drives the transmission gear set 32 to rotate, thereby moving the rack 33 up and down. The lower pressure block 35 is located on the front side of the movable frame 20. The rack 33 is movably connected to the lower pressure block 35. The spring 34 is located below the rack 33, and its two ends are connected to the rack 33 and the lower pressure block 35, respectively. The cutting component 40 is fixed to the side of the lower pressure block 35.
[0037] Specifically, please refer to Figure 6 The transmission gear set 32 includes an input gear 321, a reduction gear 322, and an output gear 323. The input gear 321 is driven by the output end of the rotary motor 31. The reduction gear 322 meshes with the input gear 321. The output gear 323 meshes with both the reduction gear 322 and the locking teeth 331 of the rack 33. By configuring the input gear 321, reduction gear 322, and output gear 323 to reduce the rotational speed, thereby reducing the vertical movement speed of the rack 33 and improving motion stability.
[0038] Specifically, please refer to Figures 2 to 5The lower pressure block 35 is provided with a movable groove 351. The rack 33 and spring 34 are both installed in the movable groove 351. One end of the spring 34 is connected to the bottom of the rack 33, and the other end of the spring 34 is connected to the inner wall of the movable groove 351.

At the same time, a vertically placed guide shaft 352 is provided on the inner side of the movable groove 351. The guide shaft 352 vertically passes through the rack 33, so that the rack 33 is slidably connected to the guide shaft 352. Meanwhile, the spring 34 is sleeved on the outer side of the guide shaft 352. The guide shaft 352 guides the rack 33 to ensure that the rack 33 moves vertically in the movable groove 351.
[0039] In one embodiment, the lower pressure block 35 is provided with an anti-deviation wheel 353 on its side. The anti-deviation wheel 353 is rolledly connected to the outside of the anti-deviation shaft 24.

A linear bearing 354 is fixedly installed inside the lower pressure block 35. The linear bearing 354 is slidably connected to the directional shaft 25 to guide the lower pressure block 35. The cooperation between the anti-deviation shaft 24 and the anti-deviation wheel 353, and the cooperation between the linear bearing 354 and the directional shaft 25, ensures the stable movement of the lower pressure block 35 in the vertical direction.
[0040] Please see Figures 2 to 5 The cutting assembly 40 includes a blade holder 41, and a connecting block 42 is fixedly provided on the side of the blade holder 41 facing the lower pressure block 35.

The blade holder 41 is fixed inside the connecting collar 44.
[0041] During operation, the operator inputs the required cutting pressure into the touchscreen 11. The rotating motor 31 drives the transmission gear set 32 to rotate, which in turn drives the rack 33 to move up and down. As the rack 33 moves downwards, it compresses the spring 34, causing the pressure block 35 and the cutting assembly 40 to press down as well, thus increasing the cutting pressure. Conversely, when the rack 33 moves upwards, the cutting pressure decreases. The cutting pressure can be flexibly selected according to different materials to ensure cutting quality. The cutting pressure is adjusted using the rotating motor 31, transmission gear set 32, spring 34, and rack 33. In this embodiment, the spring constant of the spring 34 is 65 g / mm, and the cutting pressure is adjustable from 100 g to 1500 g, providing a wide adjustment range to meet the diverse cutting pressure requirements of different materials. It should also be noted that this embodiment uses a single spring 34; with a fixed spring constant, the cutting pressure of the cutting assembly 40 is directly proportional to the movement of the rack 33.
[0042] Compared to existing technologies, the adjustable pressure cutting mechanism 1 of this utility model is applied in a film cutting machine. It is equipped with a movable frame 20, a pressure regulating component 30, and a cutting component 40. The movable frame 20 is used to achieve horizontal movement and adjust the cutting position. The cutting component 40 cuts the material, and the pressure regulating component 30 is used to control the cutting pressure. The pressure regulating component 30 uses a rotating motor 31, transmission gears, and racks 33 in cooperation to expand the pressure adjustment range. It can flexibly adjust the pressure according to different cutting needs, ensuring that the cut product does not shift position during the cutting process, improving cutting accuracy, reducing waste of the cut product, saving costs, and helping to improve economic efficiency. The pressure regulating component 30 is driven by a motor, making pressure control convenient and quick. At the same time, it is equipped with a guide shaft 352, an anti-deviation shaft 24, and a directional shaft 25 to restrict the vertical movement of the cutting component 40, ensuring vertical cutting and further improving cutting accuracy.
