Abstract
The invention concerns a drafting system spinning roller comprising a cylindrical roller body (1) forming a slide bearing with a slide bearing bush (3) which is pushed on and axially secured. The slide bearing bush (3) comprises a cylindrical sleeve (4) which is made of a tubular plastics or plastics compound and onto which an elastomer coating (5) is extruded.
Description
The present invention relates to be used to make the spinning roller of the drafting system of yarn, this spinning roller have a columniform body of roll and one be installed in above the body of roll, constituted a cylinder-shaped sleeve sliding bearing, axial restraint, that make by the plastics that are applicable to dry running environment together and be coated in the elasticity lining that cylindrical shaft puts with it.
This spinning roller is that this roller has adopted leather and rubber as general popular roller lining as the explanation of the pressure roller of drafting system in DE-U-18 21 235.
In addition, known a kind of traversing condenser reller that is used for spinning machine from CH-A-513 995, wherein, a plastic sleeve is axially fixed in slidably as sliding bearing on the body of roll of traversing condenser reller, steel circular cylindrical roller of surface bearing outside its this respect.Plastic sleeve is that to adopt pressure casting method be that 60 powdery polytetrafluoroethylene (PTFE), percentage by weight are that 10 bronze particles and percentage by weight are that 20 graphite is made by percentage by weight under 360 to 370 ℃ temperature, like this, the sliding bearing of being made up of the body of roll and plastic sleeve is self-lubricating.
US-A-3 785 022 has illustrated a kind of weaving processing unit (plant) with central shaft, on this, pressed a canular core, to resemble Rockwell hardness that acrylonitrile-butadiene-styrene (ABS), polypropylene, nylon or Merlon make be that 95 hard rigid pipe is formed to this canular core by a kind of by one, it is a thermoplastic, also is referred to as hard rubber or phenolic resins here.This sleeving core press fit on the central shaft.Loaded onto rubber element round sleeving core, this rubber element can separate moulding on an extruder separately.Rubber element is set on the core sleeve by means of the air resilient expansion, interrupts expansion by air then and makes its retraction, so just can be fixed on around the core retainer plate solidly.The structure of Xing Chenging also is wrapped with textile belt like this, and then sclerosis 90 minutes and polish after cooling under 150 ℃ temperature.Also can the multilayer pressing, replace loading onto soft rubber tube by the air expansion.
This structure is a rigid element, and it does not illustrate bearing.Material between core sleeve and rubber element is in conjunction with can't see.
Task of the present invention is to improve spinning roller noted earlier, so that can make the simple especially and low price of manufacturing of spinning roller.
The spinning roller that this task is mentioned kind according to the front solves like this, the plastics that are cylinder-shaped sleeve are made up of resistant to elevated temperatures polymer, and the elasticity lining is directly by extruding, preferably cross-peen extruding or be coated to that cylindrical shaft puts or glued together with it by sulfuration by die casting.
Here, cylinder-shaped sleeve is formed this conduction by a kind of pipe fitting of being made by high temperature resistant polymer vulcanizable, that be applicable to dry running environment.
Comprise long filament (monofilament) with the yarn of this spinning roller manufacturing made in accordance with the present invention as short velvet fiber and long wool fiber.This spinning roller is except using in the drafting system that adopts ring spinning, also can in the drafting system of open-end-spinning, air-jet spinning and open-end spinning, use, can also be used for specific process, as Ring Can, Plyfil, Dref or the like, and in spinning is prepared, promptly in combing machine, flyer roving frame and similar machine, use.
As plastics or plastic compound, can use those thermoplastics based on polytetrafluoroethylene (PTFE)-homopolymers (PTFE), tetrafluoroethylene and hexafluoroethylene copolymer (FEP), polyether-ether-ketone (PEEK), polyimides, polyphenylene sulfide (PPS), perhaps in compound admixture for example molybdenum bisuphide, graphite, bronze, filler and fibre-reinforced similar mixture.
The elasticity lining is preferably by the acrylonitrile butadiene-copolymer (acrylonitrile butadiene rubber that with acrylonitrile content is 18 to 50%, NBR rubber) is the customizations compound on basis, acrylonitrile butadiene-copolymer (hydrogen-acrylonitrile butadiene rubber by a kind of partly or completely hydrogenation, H-NBR rubber) or by a kind of hydroxyl family content from 1 to 9% or on the basis of ethylene-propylene terpolymer rubber hydroxylation acrylonitrile butadiene trimer (X-acrylonitrile butadiene rubber, X-NBR rubber) form.
In addition, by the elasticity lining is lumped together to constitute sliding bearing sleeve with cylinder-shaped sleeve extruding and vulcanizate simultaneously, can make to make and oversimplify, and therefore between elasticity lining and cylinder-shaped sleeve, reach secure bond.Here, the manufacturing of pipeline and the manufacturing of the body of roll are irrelevant, and pipeline is axially separating with certain spacing and pipe fitting, and thus, each has all constituted a sliding bearing sleeve, and it has interior cylinder-shaped sleeve and outer lining.Yet install simply especially, because the sliding axle lining that obtains so only is inserted into and is axially fixed on the body of roll, the sliding bearing sleeve and the body of roll have constituted sliding bearing.
Structure according to spinning roller of the present invention, if the fibre length that this structure allowance will be spinned, the external diameter of elasticity lining can be smaller, perhaps thicken the wall thickness of elasticity lining greatly, particularly when the soft coating that adopts less than 70 Sha, this can improve operating characteristic and improve service life, because can grind frequently again.
At the contraction state that common plastic sliding bearing will be observed, this quality to the system yarn may produce adverse influence, and before system yarn process, the step of correct grinding elasticity lining is finished in advance on axle.
Below, the longitudinal profile schematic diagram by means of the embodiment that shows spinning roller further specifies the present invention.
The spinning roller that illustrates in the drawings has a columniform body of roll 1, this body of roll has a central sections 2 that is used to admit a swing arm that does not illustrate, in the both sides of this central sections 2, on the body of roll 1, plug a sliding bearing sleeve 3 and axial restraint respectively.Sliding bearing sleeve 3 is made up of a cylinder-shaped sleeve 4, has applied one deck elasticity lining 5 on axle sleeve.Cylinder-shaped sleeve 4 is made up of a kind of polymer resistant to elevated temperatures, that be applicable to dry running environment, and polymer is glued together by sulfuration and elasticity lining 5.Sliding bearing sleeve 3 is embedded in the axial restraint of protective ring 6b on 1 section of the affiliated body of roll in the cannelure by an annular convex shoulder 6a and one respectively.Here, the external diameter of annular convex shoulder 6a than the external diameter of separately cylinder-shaped sleeve 4 little 1/10mm.
