Further improvement of the present invention is: described cotton-cutting mechanism is the saw roller of the rotation be arranged in the frame at corresponding pressure cotton machine structure rear, and the roll surface of described saw roller is some collar plate shape saw blades or section.
Further improvement of the present invention is: two of described cotton-cutting mechanism cut and to arrange for transporting the sliver that the segments carrier pipe to winding mechanism below roller, arranged crosswise is in dividing plate both sides respectively for described carrier pipe, and carrier pipe quantity is corresponding to the sliver quantity of cutting.
Further improvement of the present invention is: described frame is also arranged corresponding with carrier pipe quantity provides the bobbin of bracing wire for the sliver be split, and the bracing wire on described bobbin is adhered to the sliver be split mutually through cutting after between the groove of roller and the fin of elastic press wheel.
Further improvement of the present invention is: described winding mechanism comprises the coiling gear of the band central through hole corresponding to the sliver quantity that cotton-cutting mechanism is cut be arranged in frame, the central through hole of described coiling gear is corresponding with the sliver of cotton-cutting mechanism institute cutting, the end face of coiling gear is arranged the roll that promising winding sliver provides coiling.
Further improvement of the present invention is: the rectangular array arrangement of described coiling gear, a gear is wherein had to be driving gear, the secondary driving gear having a row to engage successively in other coiling gear engages with driving gear, and the driven gear engaged with secondary driving gear successively in column intermeshing is arranged.
Further improvement of the present invention is: above described each coiling gear or be also provided with tension disk on the axle bed of roll.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
The present invention includes and send cotton machine structure, cotton-cutting mechanism and winding mechanism, control the co-ordination of each mechanism by controller, achieve the automatic production in alumina silicate wire rope core portion, can enhance productivity, reduce production cost.The alumina silicate rope core diameters that application the present invention produces is well-balanced, density is little, the alumina silicate rope good looking appearance of final weaving forming.
Water in the sparge pipe arranged above endless apron can soak aluminium silicate wool, prevents that aluminium silicate wool is too fluffy causes pressing obtaining not consolidation; Be arranged in the middle part of endless apron and before pressure cotton, fully can soak aluminium silicate wool, ensure consolidation effect.
The fin of elastic press wheel with cut roller groove and be engaged and coordinate, the bracing wire of cutting roller place can be compressed, prevent bracing wire loose, in disorder.
Spring is set two both can be allowed to cut roller closely cooperate cutting roller two end axles bearing place; strengthen effect during cutting knife cutting sliver; roller can also be cut by available protecting; because containing partial impurities in aluminium silicate wool; there is oarse-grained adamant sometimes; spring can make to cut roller and get out of the way these materials, and available protecting is cut roller and damaged, and increases the service life.
For ensureing that the sliver segmented enters carrier pipe smoothly, the diameter of carrier pipe need be greater than the sliver diameter be split, gap between each carrier pipe is larger than the gap of cutting between roller roll surface upper cutter, and the carrier pipe of arranged crosswise can Appropriate application space, prevents each mechanism of equipment too crowded.
Arranging corresponding with carrier pipe quantity provides the bobbin of bracing wire for the sliver be split, bracing wire keeps being synchronized with the movement respectively by two gap locations cutting roller roll surface cutting knife and the sliver be split, bracing wire is as the arbor of aluminium silicate wool, can prevent the sliver segmented from breaking, ensure the trouble-free operation of production line.
The tension disk that coiling gear or coiling axle bed are arranged for straining the coiling at bobbin place, make to be wrapped in coiling on sliver around tighter, prevent the loose disconnected bar of sliver.
