Background technology
Generally adopt at present the upper and lower drawing roller of combination in pairs that web is carried out combing and drawing-off in the web production technology, with strengthen web laterally with toughness longitudinally.
The Chinese patent publication number is CN101270514A, the patent of invention that open day is on September 24th, 2008 discloses the combing drafting method in a kind of cotton and the chemical fibre fore-spinning technique, wherein come out with and a kind ofly adopted many drawing roller to the band saw tooth feeding the device that cotton layer carries out comb and parallel cotton fibers prior to spinning and drawing-off, per two counter extensioin rollers are formed a combing drafting unit in this device, the rotating speed difference of two counter extensioin rollers, wherein each drawing roller is initiatively drawing roller, sawtooth on each drawing roller carries out drafting of sliver when sliver is carried out combing, reach by the rotating speed of regulating every counter extensioin roller cotton layer is carried out combing simultaneously, removal of impurities and drawing-off.Though this invention can be finished comb and parallel cotton fibers prior to spinning and drafting drawing-off simultaneously, improved production efficiency, but because it adopts many drawing roller to the band saw tooth to carry out drawing-off to feeding cotton layer, simultaneously on preventing, sawtooth on the following drawing roller touches mutually and causes, following drawing roller can't be moved, so reserving certain clearance up and down between the drawing roller with on preventing, following drawing roller is touched mutually, just because last, there is certain clearance between the following drawing roller, thereby cause, sawtooth on the following drawing roller can only extend into cotton and chemical fibre on, following top layer, and can't carry out the combing drawing-off, and then cause the toughness of cotton and chemical fibre relatively poor to the intermediate layer of cotton and chemical fibre.
Summary of the invention
The purpose of this utility model is to overcome can't carrying out the combing drawing-off to the intermediate layer of cotton and chemical fibre, making the relatively poor defective and the problem of toughness of cotton and chemical fibre of existing in the prior art, provides a kind of and can carry out the combing drawing-off to the intermediate layer of cotton and chemical fibre, makes the toughness of cotton and chemical fibre be used for the drafting system of web drawing machine preferably.
For realizing above purpose, technical solution of the present utility model is: a kind of drafting system that is used for the web drawing machine, comprise the last drawing roller and following drawing roller that are in contact with one another cooperation, the described upper end contact matching that goes up drawing roller and following drawing roller, the drive division at following drawing roller middle part passes on from one to another movingly by driving chain and motor; The described quantity of drawing roller down is two, comprise lower-left drawing roller and bottom right drawing roller, the upper end of lower-left drawing roller, bottom right drawing roller all with last drawing roller contact matching, drive division passes on from one to another movingly by driving chain and motor, and lower-left drawing roller, bottom right drawing roller are in contact with one another cooperation.
Described lower-left drawing roller, bottom right drawing roller include drive division, pars intermedia and contact site, the outward flange of described drive division is around being provided with pars intermedia, the outward flange of pars intermedia centers on and is provided with contact site, and contact site is along the even nadel that is provided with of the outward flange of pars intermedia.
The quantity of described nadel is at least two.
The quantity of described nadel is 30.
One end of described nadel is connected with pars intermedia, and the other end is provided with kink, is formed with knuckle between kink and the nadel, and the size of knuckle is 80 –, 100 degree.
The size of described knuckle is 90 degree.
Compared with prior art, the beneficial effects of the utility model are:
1, because a kind of drafting system that is used for the web drawing machine of the utility model comprises drawing roller and following drawing roller, following drawing roller comprises lower-left drawing roller and bottom right drawing roller, the lower-left drawing roller, the upper end of bottom right drawing roller all with last drawing roller contact matching, drive division passes on from one to another movingly by driving chain and motor, and lower-left drawing roller, the bottom right drawing roller is in contact with one another cooperation, this kind design can improve the combing of web, drawing-off efficient, in addition, the lower-left drawing roller and the bottom right drawing roller that are adopted include drive division, pars intermedia and contact site, outermost contact site is along the even nadel that is provided with of the outward flange of pars intermedia, the outer end of nadel is provided with kink, be formed with knuckle between kink and the nadel, this design can be last, following drawing roller is in contact with one another, do not exist on the basis in gap between the two, by the kink on the nadel on the web, the combing drawing-off is carried out in following top layer and intermediate layer simultaneously, thereby improves the toughness of cotton and chemical fibre.Therefore the utility model not only can carry out the toughness of combing drawing-off, raising cotton and chemical fibre to the intermediate layer of cotton and chemical fibre, and the efficient of combing drawing-off is higher.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the structural representation of bottom right drawing roller among Fig. 1.
