Abstract

The invention provides a blowing round roller extraction cutter which comprises a main shaft, a cutter body connected with the main shaft, positioning blocks which are located on the same axis with the main shaft and arranged on the end portions of the two ends of the cutter body, a first protruding stretch part which stretches out of the surface of the cutter body in a protruding mode, and a second protruding stretch part which stretches out of the surface of the first protruding stretch part in a protruding mode. A plurality of auxiliary channels are arranged inside the cutter body, a main channel arranged in a shaft center of the main shaft is arranged inside the cutter body, and the auxiliary channels are mutually communicated with the main shaft. Compressed air is guided into the main channel on the end portion of the main shaft, the extraction cutter is enabled to blow away waste materials by utilization of the compressed air in a waste material ejection process, the waste materials are prevented from being adhered to the protruding stretch parts of the extraction cutter and stacking, the waste material removing effect is improved, and the finished product rate and the production efficiency of a die cutting product are improved.

Description

technical field [0001] The present invention relates to an extraction knife, and more particularly to an extraction knife with an air-blowing round roller that removes die-cutting waste by using a protruding portion on the surface of a knife body during the process of manufacturing a die-cut product. Background technique [0002] Die-cut products generally consist of a release liner, a protective layer and an adhesive layer in between. Die-cut products are widely used in automobile manufacturing, electronics industry, especially flat panel display, mobile digital industry. According to the shape of the internal frame of the electronic product, use a die-cutting knife with a specific shape to stamp or roll to die-cut a specific shape. Then peel off the protective layer on the surface, stick the die-cut product on the inner frame of the electronic product, then peel off the release paper, and finally fix the inner frame and outer shell of the electronic product firmly with th...
