For overcoming above-mentioned defective, the invention provides a kind of metal fiber tow and the staple fibre carded sliver and mix and crush cutting method and device, it can be with crush cutting, and mixing also, two procedures unites two into one, minimizing improves the uniformity of speed of production and metal fibre blending to machine members and raw-material loss.
For achieving the above object, the present invention has adopted following technical scheme:
A, the metal fiber tow and the staple fibre carded sliver are fed the draw zone of being made up of rearmounted roller and drawing rollers simultaneously;
B, make circular metal fiber tow become flat by the pressurization roller above two rollers pressurization,
C, utilize speed official post metal fiber tow even straight cut-out in draw zone of two rollers, form continuous staggered short fiber crush cutting bar, and be wrapped in simultaneously drafted staple fibre carded sliver high speed through drawing rollers and boundling roller, form uniform blended sliver.
D, the blended sliver that will fall into the bar tube collect.
The present invention provides a kind of device of implementing said method simultaneously, comprise body, bar tube and transmission mechanism, a rearmounted roller is arranged, after this roller is conducting bar roller, drawing rollers are installed in this roller front, constitute a draw zone between two rollers, be provided with boundling roller, the top pressurization roller that respectively is equipped with of rearmounted roller, drawing rollers, boundling roller before the drawing rollers.
The utility model is described in further detail below in conjunction with accompanying drawing
Fig. 1 is that roller of the present invention is arranged schematic diagram
Fig. 2 is a drive mechanism schematic diagram of the present invention
The bundles of metal filaments that the present invention is suitable for can be fibers such as stainless steel, copper, nickel, its single fiber diameter is 4-10um, be preferably 6-8um, fracture strength is 1-5cn, for the most desirable, the metal fiber tow radical that is fed can be decided according to producing needs, is best with the 1-3 root with 2.5-4.0, the feeding radical is too much, and the metal fibre tow can not fine crush cutting.
The staple fibre carded sliver that the present invention is suitable for can be cotton, terylene, viscose glue, polyamide fibre, polyvinyl etc., it both can be a kind of carded sliver of fiber, also can be two or more staple fibre blended slivers wherein, the one group of carded sliver radical that is fed can be decided according to producing needs, but is best with the 1-3 root.The feeding radical is too much, influences the crush cutting of wire bundle.
As shown in Figure 1, behind metal fiber tow 2 and the staple fibre carded sliver 1 feeding conducting bar roller 3, enter the draw zone that constitutes by rearmounted roller and drawing rollers, form certain speed difference between two rollers, the tension force that wire bundle is subjected to surpasses the ultimate strength of fiber, simultaneously by 9 pressurizations of the rubber rollers above two rollers, make circular wire bundle become flat, this helps the cut-out of metal fiber tow on the one hand, flat tow reduced thickness on the other hand, add the support of the staple fibre carded sliver, make the suffered tension force of metal fiber tow ectonexine fiber irregular, the time that causes them to cut off has difference to lead, thereby after being cut off, metal fiber tow can form the crush cutting bar that evenly connects, be coated on the staple fibre carded sliver high speed process drawing rollers 6 that are stretched simultaneously, form and mix ripe, this falls into bar tube 8 and is collected.
Wheelbase between the velocity ratio of rearmounted roller and drawing-off Tula, pressurization roller pressure and two rollers is to concern that metal fiber tow leads disconnected key factor.The velocity ratio of two rollers is too little, and the tension force that metal fiber tow is subjected to is less, and long filament can not be broken fully, velocity ratio is too big, make the suffered tension force of metal fiber tow too short action time, easy this of whole tow rises to be broken, and can not form evenly continuous crush cutting bar.When the pressure of rubber pressurization roller was too small, too little to the grasping force of the metal fiber tow and the fiber carded sliver, metal fiber tow was difficult for leading disconnected; When pressure is excessive, because the hardness of metal fiber tow is higher, pressurization roller rapid wear, and cause whole tow to be broken easily by neat mouthful, the pressure of the every end of roller is 200-450 newton, selects for use 250-350 newton for best, and the wheelbase of rearmounted roller and drawing rollers generally is advisable with 55-85mm.
Referring to accompanying drawing 2, metal fiber tow crush cutting of the present invention comprises body, bar tube 8 and transmission mechanism in mixing and installing.In the accompanying drawings body being omitted, at transmission mechanism a rearmounted roller 4 can be arranged, is conducting bar roller 3 after this roller, drawing rollers 5 are installed in this roller front, constitute a draw zone between two rollers, the linear velocity ratio between rearmounted roller, the drawing rollers is 4-9, selects 5 to 7 for use for best.Be provided with boundling roller 6 before the drawing rollers, the top pressurization roller 9 that respectively is equipped with of rearmounted roller, drawing rollers, boundling roller, the pressure of the every end of this roller is 200-450 newton, selects 250-350 newton for best.
