The cutter body 315 is formed in the shape of a cylindrical pipe, and the cutter blade 314 is formed at the end of the cutter body 315. The cutter blade 314 serves to form the hole 1a in the synthetic resin film 1. [

In one embodiment of the present invention, for example, nine cutter members 310 are arranged in the form of a 3x3 matrix, and the cutter blades 314 of the cutter member 310 are all disposed at the same position.

The fixing table 320 is disposed under the synthetic resin film 1 and the fixing table 320 firmly fixes the cutter member 310 so that the cutter member 310 can be fixed at a designated position.

The fixed table 320 can be made of, for example, a metal material having excellent mechanical strength.

The fixed table 320 may be formed in a hollow box shape and a through hole through which the cutter body 315 of the cutter member 310 is inserted is formed on the upper plate of the fixed table 320. The cutter body 315 can be firmly fixed to the upper plate of the fixed table 320 by welding or the like.

The heater unit 330 serves to heat the heater member 310 disposed inside the fixing table 320 to a specified temperature. The heater unit 330 is disposed inside the fixing table 320 and can be coupled to the cutter body 315 of the cutter member 310.

In one embodiment of the present invention, the heater unit 330 may convert electrical energy into thermal energy to heat the cutter member 310 to a specified temperature.

When the heater unit 330 heats the cutter member 310 to 300 ° C or less, the synthetic resin film 1 may not be cut accurately, and the heater unit 330 is cut off from the cutter member 310 Is heated to 340 ° C or higher, the synthetic resin film 1 may be melted to excessively increase the size of the hole 1a, or a portion cut from the synthetic resin film 1 may be melted and deposited on the cutter member 310.

Then, the synthetic resin film 1 is moved downward together with the press unit 340, The synthetic resin film 1 is brought into contact with the cutter member 310 and the synthetic resin film 1 is mechanically and thermally cut by the cutter member 310 to produce a piece 2.

The piece 2 is received in the receptacle 372 through the inside of the cutter member 310. The piece 2 is not attached to the cutter member 310 by the negative pressure formed by the pump 374, 372).

When the drive unit 350 is operated to form the hole 1a in the synthetic resin film 1, the drive reel 200 is not operated and the drive unit 350 is operated, The unit 300 is provided with a synthetic resin film 1 having no holes 1a formed therein.

As described above in detail, the synthetic resin membrane punching apparatus according to the present invention mechanically or thermally cuts the holes so that burrs are not formed around the holes when holes are formed in the synthetic resin film, Thereby improving the quality of the perforated synthetic resin film. In addition, the perforated holes of the synthetic resin film can smoothly form the perforated holes, thereby preventing excessive increase in the winding volume when the synthetic resin film is wound on the drive reel. In addition, the synthetic resin membrane punching apparatus can quickly remove the scrap generated in the process of perforating the synthetic resin film, thereby preventing deterioration of the quality of the synthetic resin film which is generated due to the slice being adhered to the synthetic resin film.
