It will be appreciated that the pressure adjustment handle of the adjustment means is connected to the cam mechanism and the cam mechanism is connected to the roller pressurising means. Therefore, a user can manually buckle the pressure adjusting handle to further drive the cam mechanism to move so as to adjust the pressure of the roller pressurizing device on the optical film.
Optionally, in this embodiment of the application, the adjusting device 04 may further include: a width adjustment mechanism (not shown in fig. 3) which can be used for the spacing between the two guide rods 01.
Specifically, the width adjustment mechanism may be a mechanical slot type (for example, the first pressure device and the second pressure device are both provided with a slot, and a user may adjust the position of the slot according to actual use requirements to adjust the distance between the two guide rods), or a threaded type (for example, the mounting holes of the two guide rods on the first pressure device and/or the second pressure device are connected by a threaded adjustment mechanism, so that the distance between the two guide rods is adjusted by adjusting the distance between the mounting holes).
Optionally, in this embodiment of the present application, the roller pressurizing device 02 includes: a limiting device. The limiting device is respectively arranged on the first pressure device 021 and the second pressure device 022 and is used for limiting the width of the optical film passing through the roller pressure device.

Optionally, in this embodiment, the limiting structure is a flange structure, and is respectively disposed on the roller of the first pressure device 021 and the roller of the second pressure device 022.
Illustratively, a pressing roller on the side of the first pressing device 021 is taken as an example. As shown in fig. 4, one end of the pressing roller 021a of the first pressing device has a position-limiting flange 021b which is effective to limit the lateral position change of the optical film during the pressing of the pressing roller 021a on the optical film.
It can be understood that, because the limiting structure is a flange structure, the flange structure can effectively limit the transverse position change of the optical film in the extrusion process when the roller of the pressurizing device pressurizes the optical film, thereby preventing the transverse flow of the photosensitive resin from affecting the photocuring effect.
