Abstract
The utility model provides an antiwind, few oiling roller of drawing frame, includes the roller body, the roller body constitute by roller cover and roller core, the roller core the cylindric structure of step is had for the both sides shaping roller core both sides step on seted up the oil groove apart from terminal surface 5mm department, roller body both sides step cover have the roller bearing case, the roller bearing case in be equipped with spline formula store oil cover and antifriction bearing, roller cover and roller bearing case between be equipped with the dust ring. Owing to seted up oil groove and store oil cover on the roller core, prolonged the roller cycle of refueling, guaranteed nimble, long -term, the stable operation of roller, and the dust ring is equipped with between roller and bearing case, and avoid the production of greasy dirt strip, prevented that the fibre from twining the roller, reduced the machine fault rate, increased work efficiency, in addition, because roller cover outer wall is the toper structure, reduced the unnecessary friction of roller with the roller, reduced roller, roller temperature, prevented that the be full of cracks from appearing in the roller, and the resultant yarn that arouses has been bad.
Description
Technical field
The utility model belongs to field of textile machinery, particularly relates to the roller on a kind of drawing frame of spinning slivering machinery of product continuous reeling.
Background technology
Drawing frame is carried out and close drawing-off by the multiple fibers such as cotton textiles, polyester cotton blending, chemical fibre, to improve the fiber long segment uniformity, degree of stretching and the depth of parallelism, the fiber of different quality is mixed in sliver evenly, create necessary condition for obtaining good resultant yarn.Drawing rollers and upper leather roller form roller nip, grip yarn with being effective carrying out drawing-off.Drafting process medium rubber roller grips yarn by pressurization and roller, roller can be out of shape in operation process, concave, grooving, be full of cracks, seriously undermined the gripping of roller to yarn, resultant yarn details, slubbing normal yarn faults can be multiplied, and the service life of roller is also greatly affected.Roller be full of cracks causes roller lap-ups, causes bar to do bad.Roller mandrel is because of oil starvation in addition, and turns round dumb, and causing roller to beat or moving about is the main cause producing mechanical wave.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model there are provided a kind of prevent because of invalid frictional heating cause two ends turn black, be full of cracks and lap-ups causes bar to do bad and that filling cycle is short roller.
For achieving the above object, the utility model proposes antiwind, the few oiling roller of a kind of drawing frame, comprise roller body, it is characterized in that: described roller body is overlapped by roller and roller core forms, described roller core is the cylindrical-shaped structure that both sides form step, and described roller cover is for being arranged on the shuttle shape cylindrical structure on the outer wall of roller core stage casing; On described roller core both sides step, distance end face 5mm place offers twice oil groove, described roller body both sides step cover has roller cartridge housing, in described roller cartridge housing, corresponding oil groove positions is provided with spline store oil cover, and described spline store oil cover both sides are provided with needle bearing; Dust ring is provided with between described roller cover and roller cartridge housing; The end of described roller cartridge housing is provided with floral disc nylon6 chips and hook axle, and described hook axle offers store oil hole.
Further, described oil groove groove width is 4-7mm, and described oil groove groove depth is 1-1.5mm, ensures enough store oil amounts.
Further, described rolling bearing can change biserial deep groove ball bearing into, can reduce the caloric value of roller bearing at work further.
The utility model compared with prior art, its beneficial effect is: a kind of roller that the utility model proposes, roller core offers oil groove and be provided with store oil cover in the roller cartridge housing of its correspondence position, extend roller filling cycle, ensure that the running that roller is flexible, long-term, stable; And between roller and cartridge housing, dust ring is housed, avoid the generation of greasy dirt bar, prevent fiber to twine roller, decrease machine-spoiled rate, add operating efficiency; In addition, because roller cover outer wall is shuttle shape structure, decrease the superfluous friction of roller and roller, additional employing biserial deep groove ball bearing replaces traditional needle bearing, reduces roller, roller temperature, prevent roller to occur be full of cracks, and the resultant yarn caused is bad.

Detailed description of the invention
By describe in detail the utility model technology contents, structural feature, reached object and effect, hereby exemplify embodiment below and coordinate accompanying drawing to be explained in detail.
Antiwind, the few oiling roller of a kind of drawing frame as Figure 1-3, roller cover 2 forms by pressing mechanism 9 jaw that grips yarn with roller 3, allows sliver 1 carry out through the gripping of roller and roller and to close drawing-off.Whole device efficiently solves roller and twines flower and stop, and affects output, improves production efficiency, avoid roller to twine flower, controls grease and overflows, prevent greasy dirt bar from producing, and solves the mechanical wave produced because oil starvation causes revolution dumb, improves yarn quality.Roller body is made up of roller cover 2 and roller core 4, it is pyramidal structure that roller overlaps 2 two ends, roller core 4 two ends have oil groove, store oil cover 7 is contained in roller cartridge housing 6 and is enclosed within outside oil groove, roller body two ends are provided with roller cartridge housing 6, and roller cartridge housing 6 can reduce quantity of heat production effectively built with needle bearing 8.Spline store oil cover 7, floral disc nylon6 chips 10 and hook axle 11, effectively can extend filling cycle, a dust ring 5 is housed between roller 2 and roller cartridge housing 6, prevents grease from overflowing and produce greasy dirt bar and lap-ups.
Embodiment 2, can change needle bearing 8 into biserial deep groove ball bearing, reduces the quantity of heat production of bearing further, improves its service life.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalence changes done according to the utility model the scope of the claims and description with modify, be all within scope that the utility model patent contains.
