Abstract
The present invention relates to forming technology for straw fiber felt, which is characterized in that the blending ratio (weight ratio) of straw fiber and conventional fiber is 50 to 95:5 to 50. The present invention adopts a method of straw fiber laying on a conventional fiber flake roll for mixing. A device of the forming technology comprises an airflow netting machine, a needle machine and a winding cutter. The present invention is characterized in that a quantitative feeding machine composed of a feeding device and a feeding transmitting device is adopted. Because the cohesive force and winding force action of the conventional fiber is utilized, a prearranged opening machine, an opening machine and a feeding machine are replaced by the quantitative feeding machine, the blending ratio is kept unchanged, and qualified straw fiber felt products can be continuously produced; fly ash and environmental pollution can not be generated.
Description
Technical field:
The present invention relates to a kind of forming technology and equipment thereof of straw fibre felt, belong to weaving non-weaving cloth field.
Background technology:
Existing stalk is shaped and adopts paper technology and equipment thereof, and it is with stalk beating → copy paper → press filtration → oven dry to form.Because will add chemicals such as caustic soda etc. in pulping process will produce large amount of sewage and cause environmental pollution.
It compares diverse two kinds of technical schemes existing non-weaving cloth processing technology and equipment thereof with above-mentioned paper technology and equipment thereof.What it adopted is that conventional process technology is produced non-weaving cloth, promptly produces non-weaving cloth through pre-opener (pre-shredding) → opener (shredding mixing) → feeding machine (quantitatively feeding) → random web-laying equipment (air-flow shaping) → needing machine (pinprick reinforcement) → coiling cutting machine (cut-out rolling).Non-weaving cloth processing technology and equipment thereof have been stopped the pollution problem that above-mentioned paper technology and equipment thereof cause, but owing to adopt pre-opener, opener and batch mixer so be only applicable to process natural fabric or synthetic fiber or regenerated fiber and can't process stalk fibre.Reason is that stalk fibre cohesive force, the very poor meeting of entanglement power generation in pre-opener and opener is scattered in a large number and is produced a large amount of dust, and when feeding machine is fed raw material to random web-laying equipment, again since between stalk fibre cohesive force, entanglement power very poor can't be continuously feeding equably, random web-laying equipment can't be spread the uniform straw fibre felt of system continuously, causes being difficult to guarantee produce continuously and being difficult to guarantee product quality.
Summary of the invention:
The object of the present invention is to provide a kind of forming technology and equipment thereof of straw fibre felt, be scattered in a large number to solve above-mentioned stalk fibre, ordinary production is difficult to reach problems such as product quality continuously.Also eliminated simultaneously the environmental pollution that paper technology and equipment thereof caused.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of forming technology of straw fibre felt, the blending ratio (weight ratio) that it is characterized in that stalk fibre and natural fabric or synthetic fiber or regenerated fiber is 50～95: 5～50, adopt the method for the top lay stalk fibre of flocculus volume of natural fabric or synthetic fiber or regenerated fiber to mix, its convoying curtain speed is 0.3～15 meter/minute, feeding roller speed is 0.3～100 meter/minute, random web-laying equipment and needing machine output speed are 0.5～20 meter/minute, and the flocculus volume of natural fabric or synthetic fiber or regenerated fiber quantitatively is 100～300 gram/rice
2, straw fibre felt quantitatively be 100～2000 gram/rice
2
Described stalk fibre can adopt straw, wheat straw, cornstalk to make raw material; Natural fabric can adopt as cotton, numb; Synthetic fiber can adopt as cellulose fibre, polypropylene fibre, terylene, nylon, polypropylene, polyethylene composite fibre, polypropylene/polyester complex fiber, poly-lactic acid ester fiber; Regenerated fiber can adopt the fiber of making as with buckram corner piece material, old cloth, once visited place blanket shredding;
The equipment of the forming technology of described straw fibre felt, comprise random web-laying equipment, needing machine, coiling cutting machine, it is characterized in that also comprising the drawing-in device of forming by hopper and feeding roller, the feeding conveyer that they are separately fixed on hopper bearing support and the convoying curtain frame and are made up of convoying curtain, transfer roller, optical press roll, combined pressure roller, rebound, annular knurl pressure roller, they all are fixed on the common quantitatively feeding machine of forming on the convoying curtain frame;
Described its hopper of drawing-in device be shaped as rectangle, adopting thickness is that 5～10 millimeters poly (methyl methacrylate) plates are made, feeding roller is that a pair of diameter is the steel fluted roller of 60～100 millimeters of φ;
Its convoying curtain thickness of described feeding conveyer is 1～2 millimeter, girth is 3～10 meters, the transfer roller diameter is the steel fluted roller of 120～200 millimeters of φ, the optical press roll diameter is the steel smooth roll of 60～100 millimeters of φ, the last pressure roller diameter of combined pressure roller is the steel smooth roll of 60～100 millimeters of φ, 2 lower compression roller diameters are 20～80 millimeters of φ, be the steel smooth roll, annular knurl pressure roller diameter is steel or the aluminium matter knurling roller of 40～80 millimeters of φ, rebound is that 1 millimeter corrosion resistant plate is made by thickness, and they all are bearing on the convoying curtain frame.
Advantage compared with prior art of the present invention is: sneak into natural fabric or synthetic fiber or regenerated fiber in stalk fibre 1., utilize the big effect of cohesive force, entanglement power of natural fabric or synthetic fiber or regenerated fiber to make to produce obvolvent between stalk fibre and tangle to guaranteeing that continuously feeding and ordinary production have been created good condition equably, this feeding manner can not produce dust yet.2. adopt the quantitatively feeding machine to substitute pre-opener, opener, feed, both guaranteed that two kinds of fiber blends were more constant than (weight ratio) in the production process, can guarantee the continuous flow rate ordinary production again, and produce up-to-standard product to machine.3. do not use paper technology and equipment thereof, eliminated environmental pollution.
