Description
Technical field
The utility model belongs to field of textiles, relates to a kind of fabric guide roll in particular.
Background technology
Cloth is carrying out it fully to be flattened in rolling, expansion or other operating procedure processes, i.e. expanding, to prevent lamination, avoid out-of-flatness and to affect quality.
Application number be 201120281860.9 Chinese patent disclose a kind of loom fabric guide roll, comprise hollow roller drum, be located at the left and right at hollow roller drum two ends silently plate with by left and right silently plate centre bore be socketed the silently axle be connected, also comprise the ebonite tube be socketed in hollow roller drum, described ebonite tube circumferential surface has the contrary swivelling chute of direction of rotation, cloth operationally launches by the swivelling chute that the direction of rotation on ebonite tube is contrary by this loom fabric guide roll, prevents lamination.But find that the tension force due to cloth various piece is different and different from the frictional force of ebonite tube in actual use, cause cloth different from cloth each position speed in fabric guide roll contact process, there is deviation phenomenon, for convenience of description, the helicla flute that now regulation direction of rotation is found sth. annoying or trying is respectively left-hand screw groove and right spiral, originally the centre position alignment of the centre position of cloth fabric guide roll therewith, the both sides of cloth are identical with right spiral contact area size with left-hand screw groove, but cloth occurs after side (left or right) sideslip, there is helicla flute side skew left in such as cloth, then cloth is corresponding reduces with right spiral contact area, increase with left-hand screw groove contact area simultaneously, left-hand screw groove is caused to be greater than to the power that cloth launches the power that right spiral launches cloth to the right left, result cloth offsets more left, cannot correct and continue selvage guide smoothly.
Utility model content
For the deficiencies in the prior art, the utility model provides one and both cloth can be flattened, and can carry out the fabric guide roll of automatic deviation correction after cloth sideslip simultaneously.
For achieving the above object, the utility model provides following technical scheme: a kind of fabric guide roll, the roll shaft comprising fabric guide roll body and coaxially arrange with fabric guide roll body, fabric guide roll body is divided into left selvage guide district and right selvage guide district by middle part, left selvage guide district corresponding by the middle part of fabric guide roll body left selvage guide district side be disposed with the first blank portion, spread district, second blank portion and correction district, spread district is provided with the first helical groove along on the circumferential surface of fabric guide roll body, correction district is provided with the second helical groove along on the circumferential surface of fabric guide roll body, first helical groove is contrary with the second helical groove direction of rotation, right selvage guide district and left selvage guide district are about symmetrical in the middle part of fabric guide roll body.
By adopting technique scheme, because right selvage guide district and left selvage guide district are symmetrical arranged about in the middle part of fabric guide roll body, so right selvage guide district is provided with the first blank portion, blank portion of spread district second and correction district equally, and first helical groove in right selvage guide district is contrary with the first helical groove direction of rotation in left selvage guide district, in like manner second helical groove in right selvage guide district is contrary with the second helical groove direction of rotation in left selvage guide district, when carrying out selvage guide, align with the middle part of fabric guide roll body in the middle part of cloth, cloth is positioned in the first blank portion, spread district and the second blank portion, first helical groove in left selvage guide district contrary by direction of rotation and the first helical groove acting in conjunction in right selvage guide district, and cloth will be sprawled and come, when there is skew in cloth, if selvage guide district skew left, cloth is by second helical groove in the left selvage guide district of contact, second helical groove in left selvage guide district makes the trend of cloth direction, selvage guide district motion to the right, and the cloth being positioned at right selvage guide district leaves the second blank portion in right selvage guide district, but still contact first helical groove in right selvage guide district, and contact area does not reduce, cloth can't be made to continue skew more, first helical groove in right selvage guide district is spread effect, it is similarly the trend making cloth have direction, selvage guide district motion to the right, now first helical groove in Jin Youzuo selvage guide district makes cloth have the trend of direction, selvage guide district motion left, the area sum of second helical groove in cloth and left selvage guide district and first helical groove in right selvage guide district will be greater than the first helical groove contact area of cloth and left selvage guide district, cloth entirety is made to have the trend of direction, selvage guide district motion to the right, if during cloth selvage guide district generation skew to the right, in like manner all automatic deviation correction can be carried out.
The utility model is set to further: fabric guide roll body is tubular, and fabric guide roll body and roll shaft removably connect.
By adopting technique scheme, different according to the width of cloth, by fabric guide roll body is disassembled from roll shaft, carry out being replaced with the fabric guide roll body matched with cloth width, even if the size in the first blank portion, spread district, the second blank portion and district of rectifying a deviation changes with the width adapting to cloth on fabric guide roll body, can be suitable for the cloth of different in width.
The utility model is set to further: roll shaft is provided with positioning convex strip, positioning convex strip and axis being parallel, and on fabric guide roll body, corresponding positioning convex strip is provided with locating slot.
By adopting technique scheme, fabric guide roll body can be made to fix with roll shaft in a circumferential direction by the cooperation of positioning convex strip and locating slot, prevent from sliding when rotating, fabric guide roll body can take off from roll shaft along locating slot, change installation simultaneously.
The utility model is set to further: positioning convex strip extends to opposite side by roll shaft side.
By adopting technique scheme, positioning convex strip will increase with locating slot contact surface, coordinate more firm.
The utility model is set to further: positioning convex strip is provided with several, and several positioning convex strips are arranged in the axial direction successively.
By adopting technique scheme, during installation, the locating slot of fabric guide roll body can pass through several positioning convex strips successively, makes fabric guide roll body be arranged on roll shaft, because the contact area of locating slot and positioning convex strip reduces, when installing or removing, frictional resistance reduces in the axial direction, facilitates installing/dismounting.
Compared with prior art, cloth both can flatten by the utility model fabric guide roll, can carry out automatic deviation correction after cloth sideslip simultaneously, can change different fabric guide roll bodies simultaneously carry out selvage guide to adapt to cloth according to the width difference of cloth.
