Abstract
The utility model relates to a drawing roller for spinning aramid 1414 fiber and belongs to the field of textile machinery. The drawing roller comprises a double-head conical surface roller core (1) and a ceramic cylinder (4), wherein the central part of the double-head conical surface roller core (1) is a conical hole or a cylindrical hole with a key slot; and the double-head conical surface roller core (1) is connected with an output shaft of a drawing machine through the conical hole or the cylindrical hole. The drawing roller is characterized in that: the ceramic cylinder (4) is coaxial with the double-head conical surface roller core (1), and is sleeved on a convex shoulder of the double-head conical surface roller core (1); a connecting locking device is arranged between an inner cylindrical wall of the ceramic cylinder (4) and a double-head conical surface of the double-head conical surface roller core (1); and two ends of the double-head conical surface roller core (1) and two ends of the ceramic cylinder (4) are connected in a locking way by using the connecting locking device. The drawing roller has the advantages of wear resistance, corrosion resistance and high efficiency; and the service life reaches over 6 months under the condition of continuous production at the spinning speed of 300 to 600m/min. The drawing roller can be repeatedly used by repairing the size of an outer circle of the ceramic cylinder.
Description
Technical field
The utility model relates to a kind of fibre spinning and uses drawing roller, and particularly a kind of drawing-off roller that is used on Fanglun l414 fibre spinning or other high-performance fiber production line belongs to field of textile machinery.
Background technology
In the production process of Fanglun l414 fiber or other high-performance fiber; Polymer solution is via the pore ejection spinning of spinnerets and in the coagulating bath moulding; The moulding tow that comes out from coagulating bath is by one or several drawing machines (being generally seven roller drawing machines) drawing-off and carry out alkali cleaning and washing simultaneously; So the acid-alkali-corrosive-resisting property requirement of drawing roller is very high.This rollers overwhelming majority of using has in the market adopted 0Cr18Ni9 or 00Cr17Ni14Mo2 stainless steel material, and through durionise after the machining, hardness is generally about HV800～1000, to reach corrosion-resistant and anti abrasive purpose.But in practical application, this structure roller is very short service life, wears no resistance, and efficient is low.Generally spin speed below 200m/min, produce continuously and must change less than one month.Basic 300～the 600m/min that has satisfied not industrialization production spins speed.
Further improved design, ceramic coated on the stainless steel surface, because ceramic coated technological problems; Coating thickness can not surpass 0.5mm, and the ceramic hardness of spraying is below HRA80, and ceramic coated density is poor; Porosity is greater than 5%; Compare with respect to chrome faced roller, it is limited that hardness improves degree, and the crocking resistance on roller surface does not solve effectively.Porosity is big, and corrosive liquid is penetrated into matrix inside easily, and corrosion proof advantage neither be fairly obvious.Therefore, the structure of this rollers needs further to improve.
Summary of the invention
The purpose of the utility model is to provide a kind of corrosive Fanglun l414 fibre spinning with ABRASION RESISTANCE and acid and alkali-resistance to use drawing roller.
The technical scheme of the utility model is: drawing roller comprises double end conical surface roller core and porcelain tube; The core of described double end conical surface roller core is the cylindrical hole of a conical bore or band keyway; Double end conical surface roller core is connected with the output shaft of drawing machine through conical bore or cylindrical hole; Described porcelain tube is coaxial with double end conical surface roller core; The porcelain jacket casing is provided with the connection locking device between the double end conical surface of the inner tube wall of porcelain tube and double end conical surface roller core on the convex shoulder of double end conical surface roller core, the two ends of double end conical surface roller core and porcelain tube connect through being connected locking device locking.
Described connection locking device comprises pressing plate, compresses tapered sleeve and lock-screw; The both sides of the convex shoulder of double end conical surface roller core axially on respectively be provided with one group of locking screw; The outside is provided with pressing plate between the double end conical surface of the inner tube wall of the porcelain tube at two ends and double end conical surface roller core; The inboard is provided with and compresses tapered sleeve; Pressing plate with compress tapered sleeve on correspondence be provided with one group and be connected screw, the two ends of double end conical surface roller core and porcelain tube are locked in the following manner and are connected: lock-screw is through connecting screw and lock screw and be connected, pressing plate through lock-screw with compress tapered sleeve and be connected; Compress tapered sleeve under the effect of lock-screw and pressing plate, be connected with the inner tube wall of porcelain tube and the double end conical surface locking of double end conical surface roller core.
The double end conical surface of described double end conical surface roller core is for being symmetrical set.
The utility model can make drawing roller reach wear-resisting, anti-corrosion, advantage efficiently; On Fanglun l414 fiber or other high-performance fiber spinning production line, spin that the utility model reaches more than 6 months service life under speed 300～600m/min, the quantity-produced condition.And can reuse through the excircle dimension of repairing the porcelain tube.

The specific embodiment
The utility model can do further to describe to the utility model through following embodiment, yet the scope of the utility model be not limited to following embodiment through the technological practical implementation of explaining in the summary of the invention.
Embodiment 1:
Referring to Fig. 1, drawing roller by double end conical surface roller core 1, compress tapered sleeve 2, pressing plate 3, porcelain tube 4, lock-screw 5 etc. and form.Said double end conical surface roller core 1 relies on conical bore or cylindrical hole to link to each other with the output shaft of main equipment drawing machine.Porcelain tube 4 is coaxial with roller core 1, and two ends respectively utilize one to compress tapered sleeve 2 and lock through each one group of lock-screw 5 of pressing plate 3 and two and be connected.
Described double end conical surface roller core, pressing plate have all adopted the 00Cr17Ni14Mo2 stainless steel material to make, and compress tapered sleeve and have adopted polytetrafluoroethylmaterial material, and the porcelain tube adopts is 99.7% Al
2O
3Pottery.99.7% Al
2O
3Its bulk density＞3.91g/cm of pottery
3, hardness＞HRA91.5, can satisfy the harsh requirement of wear-and corrosion-resistant on the roller surface treatment fully.Because the impact resistance of porcelain spare a little less than, fragility is bigger, bursts apart easily.So that has adopted the polytetrafluoroethylene (PTFE) material on the structure compresses tapered sleeve to overcome the adverse effect that the problems referred to above are brought.In addition, behind long-time use surface abrasion, can reuse through repairing porcelain tube excircle dimension.
