with conventional straight glue tanks, stable operation can only be maintained for a short period of time for large draft perforation applications, although the apparatus can operate.

After the glue dirt groove is kept away in the widen of this scheme of adoption, obviously prolonged the time of punching the drum steady operation, alleviate intensity and the time that equipment clearance was maintained, but to the perforation of big draught, required laser energy is big, and the pressure of jet stream is also big, thereby still can cause the stability of the grey influence data of punching of gluing of drum.

After the glue stain avoiding groove of the scheme is combined with the positive pressure blowing hole and the dust collection device, the stable operation time of the punching drum is obviously prolonged, the intensity and time for cleaning and maintaining the equipment are reduced, but for the punching of large ventilation degree, the required laser energy is large, the pressure of the jet air flow is also large, the long-time stable operation can be maintained, and the stability of punching data can not be influenced due to the dust adhesion of the drum.

The effect of single solution measures is limited, and the optimal solution should be to adopt combined measures, so that obvious effect can be achieved.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
