Composite fiber heating line and manufacture method
Technical field
The present invention relates to a kind of tensile strength height, endurance, folded composite fiber heating line and the manufacture method of folding, belong to composite fiber heating line and make the field.
Background technology
Granted publication CN2527054Y, title " carbon filament fiber electric heating wire ", this carbon filament fiber electric heating wire comprises the insulating coating of heating conductor wire and outsourcing, the heating conductor wire is a multi beam carbon filament fiber.Heating-up temperature is below 100 degrees centigrade, and insulating coating adopts polyethylene or polyvinyl chloride, and heating-up temperature is more than 100 degrees centigrade, and insulating coating adopts fluoroplastics or silicon rubber.Its weak point: the one, carbon filament fiber heart yearn fold resistance is poor, frangibility; The 2nd, because carbon filament fibre manufacturing technique complexity, resistance value distribution is extremely inhomogeneous, Temperature Distribution with its heating products face of making is extremely inhomogeneous, show that the local of heating surface or certain are a bit because resistance value is big, temperature rise exceeds standard, easily produce spontaneous combustion, and another part heats temperature rise and does not reach designing requirement because resistance value is little.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design that a kind of tensile strength height, endurance, folding are folded, wrinkle resistance, resistant to elevated temperatures composite fiber heating line and manufacture method.
Design: in order to realize above-mentioned purpose of design.1, the plurality of fibers silk is the design of twisted shape cordage, is one of characteristics of the present invention.The purpose of doing like this is: the single fiber silk in 2 dishes or the polydisc single fiber silk dish line is combined, just changeing doubling, can form multiply fried dough twist cordage, with multiply twisted shape cordage around the fiber reel for rope that to bobbin, can constitute the twisted shape structure, with the twisted shape cordage on the fiber reel for rope of 2 or a plurality of twisted shape structures and combine, just changeing and restrict and form multiply fried dough twist cordage heater wire, the counter-rotating of multiply fried dough twist cordage heater wire is eliminated stress promptly forms composite fiber heating line then.2, multiply fried dough twist cordage just being changeed doubling is designed to 1: 0.2 with the speed ratio that eliminates stress of counter-rotating~and 0.6 design is two of characteristics of the present invention.The purpose of doing like this is: no matter be that 2 or plurality of fibers silk are made the twisted shape cordage, still 2 or many twisted shape cordage are merged into multiply fried dough twist cordage heater wire and all have stress, if can not effectively multiply fried dough twist cordage heater wire upper stress be eliminated, multiply fried dough twist cordage heater wire after it merges will be in great confusion and can't use, so the stress that whether can eliminate effectively on the multiply fried dough twist cordage heater wire is to be related to the present invention can enter industrialization manufacturing and key in application place.The application just changeing doubling with multiply fried dough twist cordage and is being designed to 1: 0.2 with the speed ratio that eliminates stress of counter-rotating~and 0.6, both can guarantee that 2 or plurality of fibers silk made the twisted shape cordage, when can guarantee that also 2 or many twisted shape cordage are merged into multiply fried dough twist cordage heater wire, can eliminate the stress of multiply fried dough twist cordage again effectively, the multiply fried dough twist cordage after guaranteeing to make is straight, can not be in great confusion.3, be added with the aramid fiber filament fiber in the multiply cordage, or the carbon filament fiber, or aramid fiber filament fiber and the design of carbon filament fiber, be three of characteristics of the present invention.The purpose of doing like this is: the aramid fiber filament fiber has very high tensile strength, and it is incorporated in the multiply fried dough twist cordage heater wire, can improve the tensile strength of multiply fried dough twist cordage heater wire effectively; And carbon filament fiber and far infrared polyester filament fiber have far-infrared functional, can improve the heating property of multiply fried dough twist cordage heater wire, can play the good health care function again.
Technical scheme 1: composite fiber heating line, metallic fiber or be multiply twisted shape cordage, or metallic fiber or be the outer PVC of being provided with layer or polytetrafluoroethylene or the ETFE or the silicone rubber insulation layer of multiply twisted shape cordage and multiply twisted shape cordage by the filament that metal and nanoscale graphite are made by the filament that metal and nanoscale graphite are made.
Technical scheme 2: the manufacture method of composite fiber heating line, (1) combine the single fiber line in 2 dishes or the polydisc single fiber silk dish line, just changeing that doubling forms the multiply cordage and around constitute the fiber reel for rope to bobbin; (2) cordage on 2 or a plurality of fiber reel for rope is combined, just changeing and restrict and form multiply cordage heater wire; (3) multiply cordage heater wire counter-rotating is eliminated stress promptly form composite fiber heating line.
The present invention compares with background technology, and the one, eliminated the stress that is produced in the multiply cordage heater wire manufacture process effectively, avoided multiply cordage heater wire in great confusion, make multiply cordage heater wire have straight, the convenient characteristics of using; The 2nd, the aramid fiber filament fiber is incorporated in the multiply fried dough twist cordage heater wire, improves the tensile strength of multiply fried dough twist cordage heater wire effectively; The 3rd, carbon filament fiber or far infrared polyester filament fiber are incorporated in the multiply fried dough twist cordage heater wire, can improve the heating property of multiply fried dough twist cordage heater wire, have the function of far infrared health care again; The 4th, tensile strength height, endurance, folded, the wrinkle resistance, high temperature resistant of folding; The 5th, can form the electric heating wire of various functional characteristics according to user's request, can be extensively military, civilian goods are warming, the snow melt that also is suitable for airport, road, lawn is warming, also can be used for the fields such as heat tracing of the condensation and freezing prevention and the container of pipeline.

Embodiment
Embodiment 1: with reference to accompanying drawing 1.The manufacture method of composite fiber heating line, (1) combine the single fiber line in 2 dishes or the polydisc single fiber silk parcel, just changeing that doubling forms the multiply cordage and around constitute the fiber reel for rope to bobbin; (2) cordage on 2 or a plurality of fiber reel for rope is combined, just changeing and restrict and form multiply cordage heater wire; (3) multiply cordage heater wire counter-rotating is eliminated stress promptly form composite fiber heating line.That is to say, (1) 2 dishes or polydisc single fiber silk dish line are placed on the pay off rack, adjust the adjustable tension spring of every dish, then every dish monofilament is passed pilot hole and combines and penetrate in the doubling frame, just changeing doubling, directive wheel guiding, winding displacement machine winding displacement through doubling bow, with the multiply cordage after the doubling around to bobbin, constituting the fiber reel for rope; (2) with 2 or a plurality of cordage pedestal to pay off rack, and the cordage on each fiber reel for rope passed pilot hole and combine penetrate in the doubling frame, just changeing and rope, directive wheel guiding, winding displacement machine row rope through doubling bow, with and rope after the multiply cordage around to bobbin, constituting cordage heating bobbin; (3) cordage is heated bobbin and is put on the pay off rack, through doubling bow counter-rotating eliminate stress, directive wheel guiding, winding displacement machine winding displacement form composite fiber heating line.
