In one embodiment, the cutting machine further includes a frame (not shown), a driving mechanism (not shown), and a cutting tool 200, wherein the driving mechanism and the conveying mechanism are disposed on the frame. The cutting tool is arranged on the rack in a sliding mode and is connected with the power output end of the driving mechanism. The sliding direction of the cutting tool is perpendicular to the conveying direction of the conveying mechanism, so that the cutting tool can cut the conveyed optical film on the conveying mechanism. When the conveying mechanism conveys the optical film to a position corresponding to the cutting tool, the driving mechanism drives the cutting tool to slide relative to the rack so as to cut the optical film.
As shown in fig. 1 and 2, in one embodiment, the conveying mechanism includes a conveyor belt 110 for conveying the optical film. In this embodiment, the conveying mechanism further includes a plurality of conveying rollers 120, and the plurality of conveying rollers are rotatably connected to the frame. The conveyer belt is respectively sleeved on the conveying rollers, so that the conveyer belt can move relative to the frame, and the optical film is conveyed. In one embodiment, a plurality of conveying rollers are arranged on the machine frame at intervals, so that the conveying belt is more stable in the conveying process.
Referring also to fig. 3, in one embodiment, the conveyor belt comprises a thin film base layer 111, a soft layer 113, and a self-healing antistatic layer 115. The soft layer is attached to one surface of the film base layer, so that the soft layer is reliably connected with the film base layer. The soft layer has elasticity. The self-repairing antistatic layer is formed on one surface of the soft layer, which deviates from the thin film base layer.
Foretell conveyer belt, the conveyer belt includes the film basic unit, soft layer and selfreparing antistatic layer, because the one side in the film basic unit is laminated to soft layer, and soft layer has elasticity, make soft layer have better stretchability and resilience, because the one side shaping that deviates from the film basic unit on soft layer has the selfreparing antistatic layer again, the incision tool mark that makes the conveyer belt be used for carrying the surface of optical film can heal automatically in a few seconds, and the surface of conveyer belt can not the adhesion by the waste material that cuts, can drop automatically by the waste material that drops on the conveyer belt surface when the deflector roll that moves the conveyer belt is terminal to the time of moving down, can not adsorb the dust yet, in order to avoid on the dust influence is by the optical film that cuts, the problem that the optical film outward appearance is bad has the dust has been solved.
It can be understood that the self-repairing antistatic layer is formed on the side of the soft layer, which is far away from the film base layer, and the self-repairing antistatic layer has the following functions: 1) the electrostatic adsorption dust and the residual scrap of the conveying belt are reduced, and the production defects and safety accidents caused by static electricity can be greatly reduced; 2) the self-repairing antistatic layer has very good and quick incision closure function; when the cutting knife cuts through the coating, the coating can automatically and quickly rebound the cut position to completely close and repair the cut; 3) the self-repairing antistatic layer surface has no adsorbability to residual scraps left on the conveying belt after cutting, and the residual scraps automatically fall off into a given waste recovery basket in the transmission process of the conveying belt and cannot remain on the conveying film to enter the lower side of the cutting die to cause poor cutting of products.
Because the soft layer and the self-repairing antistatic layer have good self-elastic and self-repairing functions on the notched tool marks, the service cycle of the conveying belt is greatly prolonged, the manufacturing cost of the conveying belt is further reduced, and the problems of low yield of the traditional conveying belt and layering of upper and lower layers of composite materials of the conveying belt are solved; so, the finished product after cutting that bears on the conveyer belt can not produce the not smooth and phenomenon that has the broken filament in limit, and also can not the perk through cutting the basement membrane for a long time and many times, more can not appear leading to the problem of the blooming fish tail of treating cutting optical film jack-up and cutting die scraping.
