Novel rolling structure

Technical Field

The invention belongs to the technical field of rolling, and particularly relates to a novel rolling structure.

Also a comparatively common spindle formula rolling structure, the rolling mode of this structure is: the materials are wound to the other end in the forward direction according to a certain inclination angle, then are wound in the reverse direction, and are wound in a reciprocating mode in such a way, and each layer of material is provided with an overlapping part, as shown in figure 2; under a low tension, the cross section of the spindle web of longitudinal elastic composite material will form a scalloped edge in a wavy shape, as shown in FIG. 3; the resulting overall spindle roll shape resembles a football, which severely impacts the elasticity of the composite jeopardy fabric.

In the conventional winding mode, because the elasticity of the longitudinal elastic material is consistent with the winding direction, in order to avoid the weakening of the elasticity caused by excessive tension, the longitudinal elastic material is usually required to be wound under the condition of small tension and as relaxed as possible, so that the coiled material is fluffy, the winding diameter is large, but the length of the corresponding material meter is relatively short.

Therefore, a novel rolling structure is designed to solve the problems.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment is as follows: as shown in fig. 4 and 6, the novel winding structure comprises a winding core 1, wherein a coiled material is arranged outside the winding core 1 and wound on the winding core 1; the coiled material comprises a plurality of winding units which are distributed along the axial direction of the coiled core 1, the axial length of each winding unit is equal to twice the width of the coiled material, a crossing area is arranged between every two adjacent winding units, and the axial length of each crossing area is equal to one time the width of the coiled material; the winding unit is formed by combining a plurality of forward winding areas 2 and a plurality of oblique winding areas 3 at intervals; the forward winding area 2 consists of a plurality of layers of completely overlapped coiled materials, and the axial length of the forward winding area 2 is equal to one time of the width of the coiled materials; the obliquely-wound area 3 is formed by a plurality of partially overlapped coiled materials, the axial length of the obliquely-wound area 3 is equal to twice the width of the coiled materials, and a certain distance is axially arranged between every two adjacent coiled material layers in the same obliquely-wound area 3. The winding central line of the coil layer of the forward winding area 2 is superposed with the central line of the winding core 1, and the winding central line of the coil layer of the oblique winding area 3 forms a certain angle with the central line of the winding core 1.

When the width of the coil is a, when the axial distance between the adjacent coil layers in the same oblique winding area is f, the relationship between a and f is as follows: f is more than or equal to a/10 and f is less than or equal to a/2. The inclination angle of the coil layer of the oblique winding area relative to the coil layer of the positive winding area is e, and the e is 5-30 degrees. The structure is formed by winding a coiled material on a winding core back and forth along the axial direction of the coiled material. When the coiled material is wound along the axial direction of the winding core in the forward direction, the inclination angle of the coiled material layer in the oblique winding area relative to the coiled material layer in the forward winding area is E1; when the coiled material is reversely wound along the axial direction of the winding core, the inclination angle of the coiled material layer in the oblique winding area relative to the coiled material layer in the forward winding area is E2; wherein, E1 and E2 are arranged in bilateral symmetry. The number of winding layers in the forward winding area is n, and n is 1 to 10.

The preferred embodiment is: as shown in FIG. 6, the axial length of the winding core is c, the width of the coil is a, c is an integral multiple of a, and c is not less than 2a. When the axial length of rolling up the core was the integral multiple of coiled material width, the both ends of the coil stock structure of final formation flushed, and no roll core exposes, and not only convenient transportation is pleasing to the eye again, has still reduced the axial materials of roll core, has reduced the use cost of roll core.

The coiled material is a composite non-woven fabric with longitudinal elasticity. The composite non-woven fabric has a good rolling structure, and other materials with longitudinal elasticity are suitable for use, but are not limited to the existing materials, and new materials with the same performance developed in the future can also be suitable.

The specific implementation process (as shown in fig. 6):

selecting a coiled material with the width a, wherein a ranges from 50 to 300mm; selecting a winding core with the axial length of c, wherein c is 100 to 1200mm; wherein c is integral multiple of a and c is more than or equal to 2a. The corresponding coil stock equipment is prepared.

When the coiled material is movably wound on a winding core for the t time (t is an integer, t is more than or equal to 1), winding n layers (n is 1 to 10) of the coiled material on one end (end A) of the winding core along the radial direction of the winding core until a forward winding area is finished; obliquely winding the plurality of layers of the winding core in a mode that each layer has the same angle e (e is 5-30 degrees) and moves a distance f (f is more than or equal to a/10 and f is less than or equal to a/2) to the other end until the axial length of the oblique winding area is equal to 2a, and finishing the oblique winding area; and winding n layers along the radial direction (vertical to the direction of the winding core) of the winding core, repeating the process until the coiled material reaches the other end (B end) of the winding core, and winding n layers along the radial direction of the winding core to finish the t-th moving winding.

When the coiled material is movably wound on a winding core for the (t + 1) th time, winding n layers (n is 1 to 10) of the coiled material at the end B of the winding core in a direction perpendicular to the winding core until a forward winding area is finished; obliquely winding the plurality of layers of the winding core in a mode that each layer has the same angle g (g is 5-30 degrees) and moves a distance j (j is more than or equal to a/10 and j is less than or equal to a/2) to the end A until the axial length of the oblique winding area is equal to 2a, and finishing the oblique winding area; and winding n layers along the radial direction of the winding core, repeating the process until the coiled material reaches the end A of the winding core, and winding n layers along the radial direction of the winding core to finish the (t + 1) th moving winding.

The rolling of the coiled material on the roll core is carried out in a reciprocating manner according to the two moving winding modes until the rolling is completed, so that a complete rolling structure is formed.

Forward winding area: the winding direction is perpendicular to the direction of the winding core and n layers are wound to form an annular structure instead of a plane area in one axial winding from the A end to the B end (or from the B end to the A end). The ring-shaped structures have different diameters according to the position of the coil layer where the ring-shaped structures are located.

Oblique winding region: the method refers to an oblique annular structure formed by winding a plurality of layers in an oblique forward winding area instead of a plane area in one axial winding from an A end to a B end (or from the B end to the A end). The inclined ring structures have different diameters according to the positions of the coiled material layers.

A winding unit: refers to a plurality of axial winding from the end a to the end B (or from the end B to the end a) to form a plurality of annular structures with axial length 2a, including a plurality of web layers from the core to the outermost layer in the length range, without web layers intersecting with adjacent winding units, that is, only one forward winding area and one oblique winding area are taken in each axial winding, and the next winding area is within the axial length (2 a) but is counted into the next winding unit.

If the coiled material is axially wound from the end A to the end B of the winding core only once in a single direction, one winding unit only comprises a forward winding area and an oblique winding area, and the subsequent axial winding unit and the previous axial winding unit have a forward (or oblique) winding area crossed; if the web material is axially wound on the winding core k times (2 times in a reciprocating manner), a winding unit comprises k forward winding areas and k oblique winding areas, and the length of the axial direction is twice the width (2 a) of the web material; the winding is not only wound once in production, so that the winding unit is composed of a plurality of forward winding areas and a plurality of oblique winding areas.

The inner part and the outer part are combined at intervals: the mode of successively winding the inner layer and the outer layer is the combination of the inner layer and the outer layer at intervals, which is expressed in the application document.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
