Abstract
The utility model relates to field of textile machinery, particularly relates to a kind of mercerizing range parts.A kind of large drawn yarn ray machine roller amplitude-expanding device, comprise roller and roll shifting, described roll shifting has two, and the two ends roll surface of the roll shifting described in two and roller is close to, and in running, roll shifting is along the axial play back and forth of roller.The utility model large drawn yarn ray machine roller amplitude-expanding device is provided with a pair roll shifting in the both sides of roller in order to the expanding ability improving roller, fabric edge is acted on by the extra additional potential stretch of roll shifting, this not only increases the expanding ability to fabric, also alleviate to a certain extent the curved and limit of latitude close in rare through close irregular phenomenon, be conducive to applying of roller shape mercerizing range.
Description
Technical field
The utility model relates to field of textile machinery, particularly relates to a kind of mercerizing range parts.
Background technology
Mercerizing range is that cotton and COTTON FABRIC also wash the equipment except alkali with the process of concentrated caustic liquid under some tension condition.In knitting production, mainly with the processing to the cotton knitted fabric of weft-knitted tubular.Mercerizing range is primarily of compositions such as entering cloth rack, caustic dip groove, ventilation device, amplitude-expanding device, flusher and flat wash troughs, and wherein amplitude-expanding device is divided into cloth gripper formula and roller formula two kinds.
The roller of existing roller formula expanding mechanism is made up of mandrel, axle sleeve and sleeve, and on mandrel, cover has the axle sleeve of more piece bakelite or cast iron, in case mandrel is worn.There is more piece through the cast iron sleeve of rotation, between axle sleeve and sleeve, ball bearing can be had at axle sleeve overcoat.The expanding of roller is when fabric is close to the convex-shaped arc surface of roller, and warp-wise tension force produces broadwise component and widened by fabric.The factor affecting the size of expanding ability is the diameter of roller, arc radius, fabric hold angle in roller, and in general, its stretch capability is directly proportional to roller diameter and fabric cornerite, is inversely proportional to flexure plane radius; Existing roller has simple circular arc roller, because chainless mercerizing range floor space is little, therefore very large diameter roller can not be set, roller is directly excessive also can considerably increase equipment cost and operating cost, therefore existing roller shape mercerizing range stretching expanding ability is all very poor, easily produce the curved and limit of latitude close in rare through close irregular, weft yarn is arcuation, the fabric shrinkage finally obtained is high and wayward, therefore applies not extensive.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of large drawn yarn ray machine roller amplitude-expanding device in order to the expanding ability improving roller and is provided with a pair roll shifting in the both sides of roller, fabric edge is acted on by the extra additional potential stretch of roll shifting, this not only increases the expanding ability to fabric, also alleviate to a certain extent the curved and limit of latitude close in rare through close irregular phenomenon.
The utility model is achieved in that a kind of large drawn yarn ray machine roller amplitude-expanding device, and comprise roller and roll shifting, described roll shifting has two, and the two ends roll surface of the roll shifting described in two and roller is close to, and in running, roll shifting is along the axial play back and forth of roller.
Gather ball for the surface of described roll shifting.
Described roller section comprises mandrel, axle sleeve and sleeve, and described axle sleeve suit is fixed on outside mandrel, and described sleeve is hinged on outside axle sleeve by ball bearing suit, and the axis of described mandrel is circular arc, and described axle sleeve is divided into more piece, described sleeve and axle sleeve one_to_one corresponding.
Described sleeve is also set with outward and is fixed with rubber sleeve.
The utility model large drawn yarn ray machine roller amplitude-expanding device is provided with a pair roll shifting in the both sides of roller in order to the expanding ability improving roller, fabric edge is acted on by the extra additional potential stretch of roll shifting, this not only increases the expanding ability to fabric, also alleviate to a certain extent the curved and limit of latitude close in rare through close irregular phenomenon, be conducive to applying of roller shape mercerizing range.
Accompanying drawing explanation
Fig. 1 is the structural scheme of mechanism of the utility model large drawn yarn ray machine roller amplitude-expanding device;
Fig. 2 is the schematic cross-section of roller in the utility model.
In figure: 1 roller, 2 roll shiftings, 11 mandrels, 12 axle sleeves, 13 sleeves, 14 ball bearings, 15 rubber sleeves.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As shown in Figure 1, a kind of large drawn yarn ray machine roller amplitude-expanding device, comprise roller 1 and roll shifting 2, described roll shifting 2 has two, roll shifting 2 described in two is close to the two ends roll surface of roller 1, in running, roll shifting 2 along the axially play back and forth of roller 1, pulling force edge applied by roll shifting, improve drawing high fabric, meanwhile, because extra additional tensile force all acts on fabric edge, alleviate to a certain extent the curved and limit of latitude close in rare through close irregular phenomenon.
In the present embodiment, the tensile force provided in order to avoid roll shifting, because the inequality that causes of the reason of radian, makes to damage fabric in expanding process, and gather ball for the surface of described roll shifting 2.
In the utility model, the convex surface that can make roller section to keep roller in rotation process all the time with clothing in contact, play the effect of stretching, as shown in Figure 2, described roller section 1 comprises mandrel 11, axle sleeve 12 and sleeve 13, during rotation, mandrel 11 does not rotate, the axis of mandrel 11 is circular arc, axle sleeve 12 is divided into more piece, axle sleeve 12 suit is fixed on outside mandrel 11, the more piece axle sleeve string be equivalent on circular arc forms an arc roll surface, described sleeve 13 is hinged on outside axle sleeve 12 by ball bearing 14 suit, described sleeve 13 and axle sleeve 12 one_to_one corresponding, advance and the stretching of fabric is realized by the rotation of sleeve 13.
In the present embodiment, the outer also suit of described sleeve 13 is fixed with rubber sleeve 15, because fabric is in operation with alkali lye, by rubber sleeve 15 with frictional force when anticorrosive and increase expanding, can improve service life and the tensile force of roll-bending device.
