Abstract
The invention relates to a perforation film forming mechanism used for manufacturing perforation films, comprising a thin film unfolding roller, a push-up tight roller, a press-down tight roller, extruding and pricking-forming rollers and a thin film folding roller. The surface of pricking-forming roller in the extruding and pricking-forming rollers is the pricking roller surface and the pricking roller surface is internally provided with a plurality of electric heating tubes. The invention has the advantages that: 1. the structure is simple, the productivity is over 300m/min, thus greatly lowering the manufacture cost of the perforation film; 2. the forming efficiency of the micro pores of the perforation film is high and the diameter of the needles is regular; and 3. the aim of forming elliptical pores on plastic films is realized by changing the bands of the pricking-forming roller.
Description
Technical field
The present invention relates to a kind of perforation film forming mechanism and forming method that is used to make membrana perforata, belong to perforation film forming mechanism and make the field.
Background technology
CN200974333Y, title " a kind of making hole film shaped device ", comprise the film shaping device that sets gradually according to streamline, perforating device, wrap-up, described perforating device comprises support and is located at induced duct on the support, cylinder, forming net and drive unit thereof, described cylinder inboard along the circumferential direction is provided with fan-shaped negative pressuren zone, fan-shaped negative pressuren zone is communicated with induced duct to a STH by drum shaft, the other end of induced duct is communicated with the vacuum motor air entry, described forming net is located at the periphery face of cylinder rotationally, and axial side end of forming net and drive unit are in transmission connection.Its weak point: the one, complex structure, manufacturing cost height; The 2nd, the film micropore shaping efficiency is low and the pin diameter is irregular.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design the perforation film forming mechanism and the forming method of a kind of simple in structure, low cost of manufacture, pore-forming efficiency height and pin diameter standard.
Design: in order to realize above-mentioned purpose of design.1, the roll surface of the acupuncture format roll in the extruding acupuncture format roll is the design that acupuncture roll surface and acupuncture roll surface are built-in with many electric heating tubes, is one of technical characterictic of the present invention.The purpose of doing like this is: can conduct the heat to pin by roll surface owing to be positioned at the electric heating tube of acupuncture format roll, pin after the heating is when moment is pierced through film, the temperature of its dial can be located pass effectively, make the micropore standard not only after the moulding, and the hole circle can not produce aging and soft.2, the velocity of rotation of acupuncture format roll is two of a technical characterictic of the present invention greater than the design of compression roller speed in the extruding acupuncture format roll.The purpose of doing like this is: because the speed of acupuncture format roll is greater than the speed of compression roller, when certainly will cause the pin drawing plastic film on the acupuncture moulding roll surface, the pin after its heating makes the hole on the plastic sheeting of stretching form elliptical aperture.
Technical scheme 1: perforation film forming mechanism, it comprises the film let off roll, goes up the top idler roller, presses down idler roller, pushes acupuncture format roll and film take-up roller, and the roll surface of the acupuncture format roll in the described extruding acupuncture format roll is that acupuncture roll surface and acupuncture roll surface are built-in with many electric heating tubes.
Technical scheme 2: the forming method of perforation film forming mechanism elliptical aperture, it comprises the film let off roll, goes up the top idler roller, presses down idler roller, pushes acupuncture format roll and film take-up roller, when the micropore of plastics face need be shaped to elliptical aperture, the velocity of rotation of acupuncture format roll was controlled between 30～380 degree temperature of pin on the acupuncture format roll greater than the speed of compression roller and by many electric heating tubes in the control acupuncture format roll in the extruding acupuncture format roll.
The present invention compares with background technology, and the one, simple in structure, production efficiency height, per minute reach more than 300 meters, have reduced the manufacturing cost of membrana perforata widely; The 2nd, membrana perforata micro molding efficient height and pin diameter rule; The 3rd, by change band, realized purpose at plastic sheeting moulding elliptical aperture to the acupuncture format roll.
