The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The key problem in technology of the production method of seam water seepage drip irrigation pipe/belt of the present invention is to have created nonwoven that surface is provided with the thin layer that blocks water or opening foaming layer as the material of main part of drip irrigation pipe or drip irrigation zone, adopts ultrasonic wave to be interrupted the processing method of pressing and forming infiltration side seam.By means of the capillarity of non-woven fibre or open-cell foam layer, make irrigation water cross oozing out to side seam aquaporin from drip irrigation pipe/belt.On described infiltration side seam, the gap of bonding point forms penetrating passage.Drip irrigation or the infiltrating irrigation unit length amount of dripping can the spacing by bonding point be controlled, and spacing is large, and the unit interval, the amount of dripping is large during with equal pressure; Spacing is little, and the unit interval, the amount of dripping is little during with equal pressure.Bonding point spacing, shape, mistake aquaporin diameter also can be changed at any time by user demand.
Above-mentioned non-woven fabrics fiber material comprises it being mainly polypropylene fibre (PP), terylene (PET), also has the product of polyamide fibre (PA), viscose rayon, acrylic fibers, polyethylene (HDPE), polyvinyl chloride fibre (PVC) etc. commercially available product, especially surface spraying, coating or thermoplastic composite plastic film.
Above-mentioned open-cell foam is a kind of product on the plastic foam industry, sees on microcosmic that its pore all communicates, as wallpaper material.
The process equipment operation principle schematic diagram of seam water seepage drip irrigation pipe/belt shown in Fig. 1, operation principle of the present invention is that upper and lower two film spools 1,2 are carried two nonwoven that are provided with the thin layer that blocks water or the opening foaming layer material of main part as drip irrigation pipe or drip irrigation zone to ultrasonic compressing platform 12 simultaneously; Perhaps: carry block water film and another sheet single face of a slice to be provided with nonwoven fibre layers or the opening foaming layer of the film that blocks water, as the material of main part of drip irrigation pipe or drip irrigation zone.
Suppress the aquaporin excessively shown in Fig. 6 and infiltration side seam by pressing pressure roller 7 on film on ultrasonic compressing platform 12.The present invention selects hyperacoustic operating frequency 15KHZ, 18KHZ, 20KHZ, 40KHZ.Its principle is to utilize the crest position of compressional wave to transmit the gap of amplitude to plastic sheeting, in the situation that pressurization, make the molecule of two nonwoven that are provided with the thin layer that blocks water or opening foaming layer contact position mutually clash into to produce and melt, make the plastic material fusion of contact position, reach the processing purpose.Concentrate on the plastic sheeting part because this mode pressing is a contact heat, economize on electricity more than 85% than the hot pressing moulding of common drip irrigation zone.
Cross after aquaporin and infiltration side seam moulding through carry-over pinch rolls group 14, enter the cutting station, make cutting knife group 15 swords and become 100~120 degree angles above plastic tab, in the position of Fig. 6 segmentation lines 19, whole plastic sheeting of ultrasonic compressing is cut into to the seam water seepage drip irrigation zone as Fig. 9 or Figure 10 shape.The finished product drip irrigation zone is walked around idler roller group 17 and is wrapped on winding roller 18 again.Adjust the constant moment of force motor speed that drives winding roller, make wrap wire speed be greater than the linear velocity of ultrasonic compressing pressure roller cylindrical, the pulling force of generation should make every drip irrigation zone after cutting all fully flatten.
The invention provides following several technical schemes of implementing bilateral seam water seepage drip irrigation pipe/belt product for this reason:
A, bilateral seam water seepage drip irrigation pipe/belt: be by two layers of one-sided film or overlay film block water nonwoven fibre layers or the opening foaming layer a-2 thin plate of thin layer a-5, block water thin layer outwardly, nonwoven fibre layers or opening foaming layer a-2 are relative, relatively ultrasonic pressing bonds together as shown in Figure 9, formed aquaporin a-1 and two infiltration side seam a-3, the pressure water stream in passage, can walk around adhesive spots 20, by between non-woven fabrics fiber or the space of opening foamed board above side seam a-3, infiltrate into outside drip irrigation pipe/belt.
B, the bilateral seam water seepage drip irrigation pipe/belt of two film: be by the nonwoven of a slice single face film or overlay film or opening foaming thin plate a-5, there is face outwardly without face inwardly, with the single layer plastics films b-5 of other a slice equivalent material relative bonding together as shown in figure 10, formed aquaporin a-1 and two infiltration side seam a-3, pressure water stream in passage, can walk around adhesive spots 20, by between non-woven fabrics fiber or the space of opening foamed board above side seam a-3, namely micro channel infiltrates into outside drip irrigation pipe/belt.
In order to adjust the pressure of ultrasonic compressing pressure roller 7, the present invention also is provided with the pressure regulator 6 of pressing pressure roller, concrete technical scheme is, at the two ends of pressing pressure roller 7, support frame 6-2 is set, pressure roller shaft 6-5 and bearing 6-6 are fixed on plain bearing housing 6-7, spring 6-4 is set and adjusts screw 6-1 at framework upper, the framework both sides arrange chute 6-8, plain bearing housing 6-7 can move up and down along chute, by the upper-lower position of regulating plain bearing housing, regulates pressing pressure roller 7 pressure of the position with respect to pressing platform 12.
On pressing pressure roller 7, one or more groups pressing contact 7-1 is put in the spacer ring winding, and pressing contact 7-1 is circle, ellipse, rectangle or polygon fin, and spacing can require to regulate according to water yield.7-1 each group in pressing contact is for a row or multi-row, and many row pressures are closed between the 7-1 of contact and are crisscross arranged.
Foregoing description only proposes as several enforceable technical schemes of seam water seepage drip irrigation pipe/belt production method of the present invention, not as the Single restriction condition to its technical scheme itself.
