Electric heating radiation perforated porous membrane equipment and perforation method

Abstract

The invention relaters to an electric heating radiation pore membrane perforating equipment and method. Electric heating radiation energy is combined with a perforating pore forming die roll to allow pores to be distributed all over the surface of a polymer plastic membrane. The equipment comprises a controller. Two guide roll support guide plates are oppositely fixed on a frame. Two ends of the perforating pore forming die roll are mounted at the guide roll support parts of the guide roll support guide plates. Two guide blocks are in up-down slide fit with the guide grooves in the guide roll support guide plates. Two ends of an electric heating radiation air outlet die head are respectively connected with the guide blocks. The upper end faces of the guide blocks are connected with the piston rod of an air cylinder. The electric heating radiation pore membrane perforating equipment has the advantages that hot air perforation is used, pore edge burning caused by flame perforation is solved fundamentally, flexibility destroying, caused by the burnt pore edges, of the plastic membrane and secondary damage, caused by the burnt pore edges, to the skin and especially skin wound surfaces, flexibility of the pore edges is guaranteed, and pollution, caused by harmful gas, of the plastic membrane during combustion of combustible gas can be avoided fundamentally.

Description

technical field [0001] The invention relates to an electric heating radiation perforated film equipment and a perforating method which utilizes electric heating heat radiation energy combined with perforated pore forming mold rolls to force the polymer plastic film surface to form pores. Equipment manufacturing field. Background technique [0002] CN10131581B, title "Aperture mask for flame perforation", the present invention provides a method of manufacturing such an aperture mask, comprising the following steps: providing a support surface, wherein the support surface includes a plurality of lowered parts; providing a flame injector, wherein the flame burner supports a flame, and wherein the flame includes a flame tongue opposite the flame burner; at least a portion of an elongated flexible plastic film web is brought into abutment contact with the support surface; The flame of the burner heats the plastic film to create pores in the area of ​​the plastic film covering th...

Problems solved by technology

Its disadvantages: First, whether it is natural gas (mainly composed of CH 4 ), pipeline gas (the main component is H 2 、CH 4 , CO), or liquefied petroleum gas (the main component is C 3 h 8 、C 4 h 10 、C 3 h 6 、C 4 h 8 ) is a slightly toxic substance. When its combustion flame heats PET, PP, PE, and nylon plastic films, the flame melts PET, PP, PE, and nylon plastic films at the moment. The edge of the hole directly destroys the flexibility of the plastic film, causing friction to the skin, especially the wound surface, which makes the skin feel uncomfortable and affects the healing of the wound surface; the second is to use flame melting holes, and the harmful gas produced when the combustible gas burns directly Pollution to the surface of the melted plastic film and the atmosphere, affecting the safety of plastic film use
