Process capable of achieving GDL roll material die cutting and seamless material part switching

Abstract

The invention provides a process capable of achieving GDL roll material die cutting and seamless material part switching. The die cutting efficiency is improved, it is guaranteed that roll materials are stable and reliable in the conveying process, and the die cutting quality is guaranteed. A roll material conveying line is arranged to be an upper-layer conveying line and a lower-layer conveying line, automatic material cutting mechanisms are arranged at the output ends of the upper-layer conveying line and the lower-layer conveying line, slicing machines are arranged at the output ends of the automatic material cutting mechanisms, and tension control devices are arranged in the upper-layer conveying line and the lower-layer conveying line.

Description

technical field [0001] The invention relates to the technical field of die-cutting products, in particular to a technology capable of realizing die-cutting of GDL roll materials and seamless switching of materials. Background technique [0002] GDL coil material, that is, gas diffusion layer coil material, needs to be die-cut after the compounding is completed. In the existing die-cut production, a single coil material is generally set on the coil rack, and then passes through the guide roller behind the coil rack. Finish slicing in the slicing area of ​​the conveyor belt slicer. In the actual process, the material of the GDL coil is hard and fragile, and the conveying process needs to accurately control the tension. However, the existing conveying equipment cannot detect the tension in time, making the coil Fragmentation occurs during transportation; in addition, in the existing die-cutting production line, after the die-cutting of a single coil, it is necessary to wait for...

In the actual process, the material of the GDL coil is hard and fragile, and the conveying process needs to accurately control the tension. However, the existing conveying equipment cannot detect the tension in time, making the coil Fragmentation occurs during transportation; in addition, in the existing die-cutting production line, after the die-cutting of a single coil, it is necessary to wait for the new material to be loaded before die-cutting, which makes the whole production process take a long time and makes the processing low efficiency
