a die-cutting machine

Abstract

The invention discloses a die cutting machine. The die cutting machine comprises a feeding conveying device, a die cutting device and a discharging conveying device which are sequentially arranged. The die cutting device comprises a rack, guide pillars and a punching die. The discharging conveying device comprises a tension detection device used for detecting tension of the edge portions of the two sides of a material belt. By means of the die cutting machine, a straight-edge cutting head is arranged on the radial outer side of each outer punching cutting head so that when an electric conduction ring is punched, the straight-edge cutting head can cut out a straight cutting opening on a waste material on the outer side of the electric conduction ring, and the base material waste material is divided into multiple small waste material bars through the straight cutting openings. The small waste material bars are easily separated from a material belt base layer, the pulling force on the electric conduction ring on the base layer is small during separation, and therefore the electric conduction ring cannot be pulled to fall during waste material separation, and waste of the electric conduction ring is avoided. In addition, the tension of the edge portions of the two sides of the material belt can keep consistent through the die cutting machine, and therefore the problem that the material belt is deflected can be avoided.

Description

technical field [0001] The invention relates to the technical field of die-cutting equipment, in particular to a die-cutting die. Background technique [0002] In the prior art, the conductive ring used on the CPU of the notebook computer is generally produced by a die-cutting machine. During the production process, the inner punch of the punching die cuts out the inner material of the conductive ring, and the outer punch punches out the outer material of the conductive ring. This punching die has the advantage of simple structure. [0003] However, in the production process, due to the small slit cut by the outer punch, when the waste material outside the conductive ring is separated from the bottom tape during the waste discharge process, it is easy to cause the conductive ring to be pulled off from the bottom tape at the same time. problem, resulting in wasted conductive ring. [0004] And in actual work, because the pressure exerted by the die-cutting machine on the tw...
