[0016] The paper air hole processing equipment provided by the present invention is environmentally friendly and pollution-free, has high processing efficiency, and can solve the problems of reducing energy consumption and eliminating the generation of harmful gases.

[0017] The paper air hole processing equipment of the present invention first connects the air inlet to a high-pressure air supply device (air supply compressor). Its operating principle is that the paper is moved synchronously through the cooperation of an endless steel belt and a roller assembly. Under the action of high-pressure air, the high-pressure air is released from the second through hole and passes through the first through hole. In this process, the high-pressure air passes through and penetrates the paper to punch holes. No harmful gases are produced during the punching process, which is very environmentally friendly. The aperture of the first through hole can be the same as that of the second through hole, or the aperture of the second through hole can be slightly larger than that of the first head hole, thereby ensuring the aesthetic shape of the perforation on the paper.

[0018] Among them, through the action of the internal support block, the high-pressure air can only be released in the direction of the annular steel belt, thereby reducing ineffective pressure release and saving energy consumption.

[0019] Among them, the connecting nozzle of the air collecting tank is connected to the dust suction device, and the dust suction device is used to clean the fine paper scraps generated by the perforation in time, further ensuring that the working environment is clean and pollution-free.

[0020] The cooperation of the paper roll feeding device increases the working performance of the present invention, and can achieve braked and continuous punching operation. BRIEF DESCRIPTION OF THE DRAWINGS
