Die cutting device for conductive cloth indentation lines

Abstract

The invention relates to a die cutting device for conductive cloth indentation lines. The die cutting device is used for carrying out die cutting on indentation lines on a conductive cloth material strip, and comprises an upper die base and a lower die base which is arranged below the upper die base and matched with the upper die base. The lower surface of the upper die base is provided with an indentation line cutter, and the lower die base is provided with a silicone pad matched with the indentation line cutter and a material blocking mechanism matched with the conductive cloth material strip. Compared with the prior art, through arranging the silicone pad on the lower die base, the conductive cloth material strip and the indentation line cutter are supported flexibly from below, the indentation line cutter is ensured to be capable of being pressed into the conductive cloth material strip completely, so that the depth of the indentation lines is obvious, the compactness is good, therebound speed is slow, the imprint is not prone to recede and disappear, the retention is good, and the conductive cloth material strip can be effectively prevented from being lifted by the indentation line die cutter, thereby ensuring the normal proceeding of the continuous die cutting process.

Description

technical field [0001] The invention belongs to the technical field of conductive cloth, and relates to a die-cutting device for creasing lines of conductive cloth. Background technique [0002] Conductive cloth is woven from nylon or polyester fibers coated with metals such as copper and nickel on the surface. It has extremely high conductivity and shielding efficiency, and has anti-oxidation and anti-corrosion properties. It is ideal for shielding various electronic products. Material. When conductive cloth is used, it is often necessary to wrap it outside the component. Since the inside of the bent conductive cloth has an elastic bending tension to restore it to its original shape, when the bending tension inside the conductive cloth is greater than the adhesive force between the two layers of conductive cloth that are bonded to each other, the conductive cloth is easy to spread out. Leave the adhesive side of the conductive cloth exposed. In order to release the bendi...

Problems solved by technology

However, although this type of device can die-cut the indentation line on the conductive cloth, the retention force of the indentation line is poor and the rebound is fast. Generally, after 24 hours of storage, the imprint of the indentation line will be significantly weakened. Even disappear, seriously affecting the normal use of conductive cloth
