Abstract
The utility model relates to field of textile machinery, particularly relates to a kind of mercerizing range parts.The even expanding roll-bending device of a kind of compression type, comprise roller and pressure roller, described pressure roller is arranged on the middle part of roller, and the roll surface of pressure roller and roller is close to.The even expanding roll-bending device of the utility model compression type is in order to improve expanding uniformity, have employed a pressure roller be arranged in the middle part of roller and offset a part of tensile force produced by flexure plane, make also can obtain, through close uniform fabric, being conducive to applying of roller shape mercerizing range on chainless 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 expanding mechanism is all that one or more simple circle arc roll surface layout forms, and it is little that this kind of bend roller mechanism of battery has floor space, the feature of compact conformation; But because of the stressed natural unequal reason of circular arc, easily produce the curved and limit of latitude close in rare through close irregular, weft yarn be the problem such as arcuation and the control of door width difficulty, therefore applies not extensive.
Summary of the invention
Technical problem to be solved in the utility model is to provide the even expanding roll-bending device of a kind of compression type to improve expanding uniformity, have employed a pressure roller be arranged in the middle part of roller and offset a part of tensile force produced by flexure plane, to solve in prior art easily produce the curved and limit of latitude close in rare through close irregular, weft yarn is the defect of arcuation, improves the quality of fabric.
The utility model is achieved in that the even expanding roll-bending device of a kind of compression type, and comprise roller and pressure roller, described pressure roller is arranged on the middle part of roller, and the roll surface of pressure roller and roller is close to.
The two ends of described pressure roller are provided with hydraulic cylinder, and the take-off lever of described hydraulic cylinder promotes the middle part that roller pushed down by pressure roller.
Described pressure roller is the circular arc of indent, and the roll forming of pressure roller matches with roller.
The interior concaved circular cambered surface radius of described pressure roller is slightly larger than the bending radius of roller.
The even expanding roll-bending device of the utility model compression type is in order to improve expanding uniformity, have employed a pressure roller be arranged in the middle part of roller and offset a part of tensile force produced by flexure plane, make also can obtain, through close uniform fabric, being conducive to applying of roller shape mercerizing range on chainless mercerizing range.
Accompanying drawing explanation
Fig. 1 is the structural scheme of mechanism of the even expanding roll-bending device of the utility model compression type.
In figure: 1 roller, 2 pressure rollers.
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, the even expanding roll-bending device of a kind of compression type, comprise roller 1 and pressure roller 2, described pressure roller 2 is arranged on the middle part of roller 1, pressure roller 2 is close to the roll surface of roller 1, and operationally, fabric is pressed in roller 1 by pressure roller 2, counteract drawing high in the middle part of fabric to a certain extent, make the expanding of fabric on latitude direction more even.
In the utility model, the two ends of described pressure roller 2 are provided with hydraulic cylinder 3, and the take-off lever of described hydraulic cylinder 3 promotes the middle part that roller 1 pushed down by pressure roller 2, to provide thrust by hydraulic cylinder 3, make thrust can free adjustment as required, achieve the accurate control to expanding uniformity.
It should be noted that, under normal circumstances, in order to make roller and pressure roller can proper engagement, described pressure roller 2 be the circular arc of indent; In order to improve the uniformity of expanding further, the interior concaved circular cambered surface radius R of described pressure roller 2
1slightly larger than the radius of curvature R of roller 1
2, the tensile force that the region at such Yue Kao center is cancelled is more, achieves consistent part stressed on latitude direction.
