Description

The fabric wrinkle-free roll of dyeing machine

The present invention relates to the dyeing machine in the textile industry, especially relevant in the printing and dyeing process, prevent and remove the wrinkle resistant roller of the dyeing machine of the wrinkle bar on cloth or other material fabric.

At present, dyeing machine, for example efficient open soaper in wet cloth drying machine and the open width milling train etc., produces the wrinkle bar for preventing fabric through printing and dyeing processing back, and the expanding device is installed in these machines of being everlasting, so that reach wrinkle resistant and purpose smoothing wrinkle.Usually the expanding device that uses in dyeing machine mainly contains two classes, and wherein, a class is jam plate and screw roller, and another kind of is the rubber bend pipe.Although jam plate and screw roller profile are slightly different, its action principle is consistent, and they all reach the purpose of wrinkle resistant expanding by the different rotation directions of the left and right sides spiral that forms in its surface.But the thread groove of these plates or roller is easy to wearing and tearing, even wearing and tearing back generation breach, and contamination.This wearing and tearing and breach can stay cut to fabric, scratch and broken hole.In addition, cut and slight scratch meeting produce vitta, the defective that serious scratch and broken hole then make product composition remedy after dyeing.Simultaneously, wearing and tearing and contamination can make the thread groove of these plates or roller flatten again and cause the effect that loses wrinkle resistant expanding.The rubber roller of expanding device is to utilize concave arc to make in the specified cornerite scope of 180 ° of convex arcs fabric in the above by reaching the effect of wrinkle resistant expanding, so it is arc and from the teeth outwards with rubber sleeve to make arc.For this reason, in use must always determine the installation direction of the bow portion of roller, be fixed with screw again according to the fabric sender.This had both required knack for operating personnel, not be afraid of trouble again.; cause is in process; the influence that can be subjected to vibrating in the tension force of fabric and the machine run again inevitably makes roller place angle and produces displacement; in case existing, angle changes; the effect of its wrinkle resistant expanding will lose; the broadwise that forms fabric when serious is shunk, and plays the adverse effect that increases wrinkle bar or wrinkle level.In addition, the rubber sleeve of roller is easy to wearing and tearing and produces rough hollow, makes cloth or other material fabric work in-process the warp-wise unbalance stress occur, and defectives such as broadwise bending influence the wrinkle resistant function of wrinkling of going.Simultaneously, because the wearing and tearing of rubber sleeve also directly have influence on the service life of roller, so general roller must be changed after having used 3-4 month.

The present invention seeks in order to overcome the various shortcomings of above-mentioned screw roller and bending rubber, and a kind of installation direction requirement of not having is provided, and the good wrinkle resistant effect of going to wrinkle is arranged, economy and service life is the fabric wrinkle-free roll of long dyeing machine.

For achieving the above object, fabric wrinkle-free roll of the present invention mainly comprises the work roller, support plate and bolster.Wherein, in the middle of described work roller is made and is positioned at by one and the pipe and two of the surface band circular arc circular cone tube that is positioned at pipe both sides and smooth connection mutually form.Described bolster is made by solid hopkinson bar or is made of two solid axle journal bars that are positioned at two and a hollow pipe that is positioned at the centre.Described support plate has the 4-20 piece ringwise, and support plate can be inserted in described bolster and spaced apart and fixed thereon.The tube face of work roller can fix by the side face of screw and support plate.Have 1 at the effect roll surface described in the design with respect to its symmetrical centre face or longitudinal axis (00'): 15-1: 30 tapering.Wrinkle resistant roller is like this bleachinged and dyeing at cotton, polyester-cotton blend, silk, hair fiber crops, towel and coverlet etc. has the good wrinkle resistant wrinkle effect of going in the printing and dyeing processing.And this fabric wrinkle-free roll adopts stainless steel system, as 1Cr18Ni9Ti or 1Cr18Ni12Mo2Ti, can not stain incrustation and durable in use.

The fabric wrinkle-free roll of dyeing machine of the present invention has reasonable in design, simple in structure, so again because of need not transmission device or special support apparatus easy to installation and maintenance, and use wide, as being installed on the multiple dyeing machine, various fabrics being carried out the wrinkle resistant preliminary treatment or the processing of wrinkling of going, its product quality effect exceeds 1-2% than various plates or roller prior art, respective action, its manufacturing cost then only be original half, and long service life.

Fig. 1 is the cut-away view of wrinkle resistant roller of the present invention.

Referring to Fig. 1, the fabric wrinkle-free roll main member has work roller 1 in the present invention, support plate 2 and bolster 3.Constitute and form level and smooth surface each other by the pipe 4 of a circular arc and each 5 in circular cone tube of two as 1 of the work roller of wrinkle resistant roller and be connected.In preferable design, the circular cone tube 5 of work roller also can weld institute relatively by two half-conical tube faces and constitute.Like this, the mode of available compacting replaces drawing or turning in the process of circular cone tube, and processing technology is simplified.

The effect with wrinkle resistant smoothing wrinkle is at first considered in the selection of the tapering of wrinkle resistant roller 1, secondly is the fabric scope that can process.In this case, the tapering of work roller is chosen in 1: 15-1: in 30 scopes, really played the effect of wrinkle resistant smoothing wrinkle effectively, this will further specify below, and, applicable to the wrinkle resistant expanding processing of spinning thin ORGANDY, thin silk, melton yarn or the like fabric from thicker Henggong satin, satin drill satin, dacron drill, Oxford.

The wrinkle resistant wrinkle improvement effect of wrinkle resistant roller of the present invention is to utilize the each point linear velocity on the work roller tube face inconsistent, and make open width fabric in the processing through on the work roller tube face time, linear velocity from the center to two reduces gradually, form the lead and lag in the fabric operation, thereby can overcome and improve little and the unstable and radially wrinkle bar that cause of radial tension that the expanding device of prior art produces usually effectively.Simultaneously, again can be by the certain taper of work roller, making the both sides of fabric produce sliding force from inside to outside increases weft tension, further improves the inhomogeneous of radial tension again, thus both complement each other and reach radially wrinkle resistant and go to wrinkle and the expanding effect of broadwise.In use, for thin fabric, require the cornerite face big, self downslide amount is also big, thus to select bigger tapering, but tapering is crossed conference and is made weft tension excessive, radial tension is inhomogeneous, cause the skew of weft of fabric, not only do not have wrinkle resistant effect but also make and spin the amount reduction, the tapering upper limit of the roller of for this reason working is selected in and is not more than 1: 15.For thick fabric, require the cornerite face little, self downslide amount is also little, is to guarantee the radial tension equilibrium, so the tapering of work roller will select a little bit smallerly, to reach best wrinkle resistant expanding effect.On the contrary, if select too smallly, then can influence the imbalance of radial stress again conversely, it is stressed too small to produce broadwise, can not get good wrinkle resistant expanding effect, and for this reason, the tapering lower limit of work roller should not be less than 1:30.

Described support plate 2 is an annular.The quantity of support plate 2 can be selected according to the size of wrinkle resistant roller or length and stressing conditions, at least 4, establishes 8 in this case.They are installed in the two and the centre of work roller 1 in mode spaced apart, make the tube face that supports work roller 1 equably.In described support plate 2, be positioned at the support plate 2 of pipe 4 both sides in the middle of the work roller 1, on their opposite face, have side face rank shoulder, the part of described pipe 4 can be located in or put and lean against that this rank shoulder is gone up so that location firmly.

Bolster 3 of the present invention comprises the two solid axle journal bars 6 that are positioned at two and is positioned at a middle hollow pipe 7.Two of hollow pipe 7 in the middle of the rear portion of solid axle journal bar 6 is made and can be inserted.Bolster 3 adopts intermediate hollow pipe 7 in the present embodiment, is in order to reduce the weight of whole wrinkle resistant roller, to make whole roller in light weight, being easy at cloth through its rotation of out-of-date drive.The support plate of being adorned on the bolster 3 is fixing by welding.In addition, the tube face of work roller 1 also is connected with support plate mutually with securing member, to reach the good reinforcement effect of this face.

Because wrinkle resistant roller of the present invention has similar olivary profile, thus the requirement of installation direction had when unlike bending rubber, working, thus easy for installation, in use need not adjust specially again.In addition, fabric can be selected arbitrarily in 30 °-180 ° angular range with the cornerite of the contact-making surface of the tube face of work roller in process, for example Bao fabric can be more greatly because of soft cornerite, and in thick fabric certain anti sag property is arranged, cornerite can be a little bit smaller, can reach the comparatively satisfied wrinkle resistant wrinkle effect of going.Moreover, because wrinkle resistant roller adopts the stainless steel manufacturing, can more and more improve through the surface smoothness of using the tube face, sliding force is increasing, can further improve the broadwise pulling force, and the effect of wrinkle resistant expanding is become better and better.
