Problems solved by technology

[0002] The previous conveyor belt for optical film cutting has a single-layer structure, and the single-layer structure can only be made of one material, either soft or hard. The soft conveyor belt is volatile and has a low service life. The hard conveyor belt does not deform, but it will damage Cutting dies reduce the service life of the cutting dies, so a conveyor belt that will not damage the cutting dies and is not easily denatured is particularly important

Embodiment 1

[0031] see figure 1 , a kind of soft and hard heterogeneous conveyor belt guide film, including a base film 2 and a surface film 1, the surface film 1 and the base film 2 are composited, the base film 2 is a hard film, and the surface film 1 for soft membranes.

[0032] Preferably, the bottom film 2 is made of hard material, and the hard material is biaxially stretched PET, ABS, or stainless steel belt.

[0033] Preferably, the surface film 1 is made of soft material, and the soft material is PVC, EVA, PE, PU, ​​PO, PA, soft polyester.

Embodiment 2

[0035] The same as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0036] see Figure 2-6 ; The preparation method of the soft and hard heterogeneous conveyor belt guide film comprises the following steps:

[0037] (1) Place the bottom film 2 on the unwinding roller 31, place the surface film 1 on the composite roller 35, and make the bottom film 2 on the unwinding roller 31 flow to the glue roller 32 through the first guide roller 331 On, apply glue evenly on the surface of the base film 2;

[0038] (2) The bottom film 2 coated with glue is guided into the drying box 34 by the second guide roller 332 for baking;

[0039] (3) After the baking is completed, the third guide roller 333 guides the flow to the compound roller 35, so that the surface film 1 is compounded on the bottom film 2;

[0040] (4) Guide the laminated film to the fast winding mechanism through the fourth guide roller 334 for fast winding.

[0041] Further, the fast winding mechani...

Abstract

The invention belongs to the field of thin film technology, and specifically relates to a soft and hard heterogeneous conveyor belt guide film, including a base film and a surface film, the surface film and the base film are compounded, the base film is a hard film, and the The surface film is a soft film, which adopts a double-layer composite structure, with a layer of hard material as the substrate, and the light material is combined with the hard material. When cutting, the light material touches the knife mold to ensure that the cutting process is accurate. The upper mold is not damaged during the cutting process, and the hard material is used as the substrate to ensure that the conveyor belt remains flat and does not deform during the cutting process. Both are considered at the same time, which effectively solves the problem of the single-layer conveyor belt during use. .

Description

technical field [0001] The invention belongs to the technical field of thin films, and in particular relates to a soft and hard heterogeneous conveyor belt guide film. Background technique [0002] The previous conveyor belt for optical film cutting has a single-layer structure, and the single-layer structure can only be made of one material, either soft or hard. The soft conveyor belt is volatile and has a low service life. The hard conveyor belt does not deform, but it will damage Cutting dies reduce the service life of the cutting dies, so a conveyor belt that will not damage the cutting dies and is not easily denatured is particularly important. Contents of the invention [0003] Aiming at the problems in the prior art, the object of the present invention is to provide a conveyor belt guide film with heterogeneity of soft and hard. [0004] In order to achieve the above object, the present invention adopts the following technical solutions to achieve: [0005] The ut...
