Abstract

The utility model relates to a dyeing cylinder body used for yarn impregnating, in particular to a dyeing bobbin with radial contraction. According to the technical proposal, the dyeing bobbin with the radial contraction comprises a hollowed-out cylindrical body surrounded by a plurality of warp strips, the cylindrical body is a conical body with a small upper end and a large lower end, both the upper end and the lower ends of the cylindrical body are open, limit blocks are arranged on the opposite side wall of the adjacent warp strips, weft strips are arranged between the two limit blocks, a connecting rod is arranged between the top end parts of the two adjacent warp strips, a folded edge extended out of the cylindrical body is arranged between the lower end parts of the two adjacent warp strips, and the connecting rod and the folded edge are arranged in a staggered manner. The radial contraction can be reduced during the dyeing process, the elastic yarns can be reeled under the tension state during the dyeing process and can be dyed and dried under certain contraction state, and the elastic yarns still have elasticity after being dyed.

Description

But the dyeing bobbin of radial contraction

Technical field

The utility model relates to the dyeing cylindrical shell that a kind of yarn is contaminated usefulness, but especially a kind of dyeing bobbin of radial contraction.

Background technology

Yarn dip-dye mode has reeled yarn to contaminate and two kinds of cone dyeings, and latter saving of labor, water saving, hard waste are few, Functionality, quality and appealing design is a kind of advanced technology.Yarn bobbin dyeing is that yarn is wound on the supporter (bobbin) that is covered with passage (eyelet) by certain density and weight, is commonly referred to as " winder ", reinstalls and dyes machine, rely on the effect of dying the machine circulating pump, dye liquor penetrates circulation in layer, dyes, and then through dehydration, oven dry.Dyeing bobbin was made by stainless steel in the past, and present more use engineering plastics.Dyeing bobbin is the revolving body of a hollow, can be cylindrical, also can be round table-like, and cylinder round platform disjunctor shape is also arranged.In order to make dye liquor evenly penetrate circulation swimmingly in yarn, the bobbin surface is covered with eyelet, and its shape has circle, ellipse or polygon.In the majority with quadrangle at present, it is vertically forming with laterally the latitude bar is crossing through bar by bobbin.

The existing bobbin overwhelming majority is a rigidity, is made up of warp, latitude bar, is enclosed construction, and whole bobbin shape and change in size are less.But vertically a small amount of or horizontal (diameter) variable bobbin was arranged once also, as stainless steel wire helical spring bobbin, the collapsible bobbin of stainless steel sheet| books formula, the collapsible bobbin of corrosion resistant plate spring bus, the easy compressing hole bobbin of engineering plastics, but in using some problems are arranged all, thereby use face is less.

There is part to have elasticity in the yarn, as spandex core-spun yarn, polyester low stretch yarn, the high-elastic yarn of nylon, acrylic bulk yarn etc., they can produce contraction, typing when dyeing, if under tensioning state, dye, the elasticity of yarn will be subjected to very big loss, can not embody the elasticity style that has of elastomeric yarn itself, thereby the yarn dyeing industry wishes to allow this type of yarn reel under tension state, and under certain contraction state, dye, dry, the best method that realizes this requirement is to adopt a kind of radially contractile dyeing bobbin.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of radially collapsible, make when winder elastomeric yarn can under tension state, reel, in dyeing, oven dry under certain contraction state and make the dyeing bobbin that still has the elasticity style after the elastomeric yarn dyeing.

The technical scheme that provides according to the utility model, but the dyeing bobbin of described radial contraction comprises the hollow out cylinder that is surrounded through bar by some, this cylinder is the cone that the upper end is little, the lower end is big, and the equal opening of cylinder upper/lower terminal, adjacent two opposing sidewalls through bar are provided with limited block, be provided with the latitude bar between two limited blocks, between the top ends of bar, be provided with connecting rod adjacent two, between the top ends of bar, be provided with the flange that outside cylinder, stretches out adjacent two, and described connecting rod and flange are and shift to install.

L-shaped or the circular arc of described latitude bar.Described connecting rod is circular arc.

The utility model the time can be realized radial contraction in dyeing, make when dyeing elastomeric yarn can reel under the tension state, dyeing under certain contraction state, oven dry, still have the elasticity style after making elastomeric yarn dyeing.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: it comprises the hollow out cylinder 2 that is surrounded through bar 1 by some, this cylinder 2 is the cone that the upper end is little, the lower end is big, and the equal opening of cylinder 2 upper/lower terminals, adjacent two opposing sidewalls through bar 1 are provided with limited block 3, be provided with latitude bar 4 between two limited blocks 2, be provided with connecting rod 5 adjacent two between the top ends of bar 1, adjacent two through being provided with the flange 6 that stretches out between the bottom of bar 1 outside cylinder 2, and described connecting rod 5 is with flange 6 and shifts to install.Described latitude bar 4 L-shaped or circular arcs, described connecting rod 5 is circular arc.

The utility model vertically constitutes a hollow out cylinder 2 (being revolving body) through bar 1 by three-back-shaped, the equal opening of cylinder 2 upper and lower ends, and the free end for open can shrink or be out of shape when stressed, thereby makes the diameter of cylinder 2 make corresponding deformation.In order to make cylinder 2 have enabling capabilities preferably, between bar 1, can be added with the horizontal latitude bar 4 of some groups of " L " shapes or arc connection in reversion, laterally why latitude bar 4 will become " L " shape or arc, it is variable angle when stressed, thereby help cylinder 2 vary in diameter, also help simultaneously initial volume around the time stationarity.In order to control the contraction scope, and guarantee the dye liquor circulation road, vertically designed some groups of limited blocks 3 on bar 1, when adjacent limited block 3 contacted, cylinder 2 just can not shrink again.

For make yarn on the cylinder 2 be unlikely to come off and unwinding smooth, be provided with flange 6 at the big end (lower end) of bobbin, make a yarn " seat " thereon.

In order to increase the yarn dyeing amount, upper and lower two dyeing bobbin sockets of the present utility model can be used.For cylinder 2 is successfully carried out, also can " tube core " be arranged supporting design, when winder is had any problem, the tube core can be filled in the cylinder 2, to be fixed on the bobbin winder reel cage.

Claims (3)

1, but a kind of dyeing bobbin of radial contraction, it is characterized in that: it comprises the hollow out cylinder (2) that is surrounded through bar (1) by some, it is little that this cylinder (2) is the upper end, the cone that the lower end is big, and on the cylinder (2), the equal opening in following two ends, adjacent two opposing sidewalls through bar (1) are provided with limited block (3), be provided with latitude bar (4) between two limited blocks (2), between the top ends of bar (1), be provided with connecting rod (5) adjacent two, adjacent two through being provided with the flange (6) that stretches out between the bottom of bar (1) outside cylinder (2), and described connecting rod (5) is with flange (6) and shifts to install.

But 2, the dyeing bobbin of radial contraction as claimed in claim 1 is characterized in that: the L-shaped or circular arc of described latitude bar (4).
