Description
Technical field
The utility model belongs to field of textiles, relates to a kind of drawing machine of field of textiles stretching chemical fibre in particular.
Background technology
Stretching manufactures requisite important procedure in chemical fibre process, be often called as the second stage that chemical fibre is shaping, or be called post forming.Be not only the necessary means that the physical and mechanical property of chemical fibre is improved, and be the critical point of the quality that its former each procedure of inspection carries out.
Large molecule in drawing process in chemical fibre is along chemical fibre axle orientation, form the intermolecular force that ice adds hydrogen bond, dipolar bond and other types, the fracture strength of chemical fibre is significantly improved, and ductility declines, and ABRASION RESISTANCE and the fatigue strength to various dissimilar deformation also significantly improve.
Before and after using in chemical fibre drawing process, twice drawing machine stretches, make it that there is certain brute force and elongation, tow between the twice drawing machine of front and back is stretched because of the difference of the speed on drawing roller surface, the ratio of the draw roll superficial velocity of twice drawing machine is draw ratio, but in fact there is skidding on drawing roller surface in tow, resultant draft multiple will be lower than theoretical value, make the chemical fibre of production department reach actual demand, cause the birth of a large amount of substandard products.
Have at present and increase backer roll above or below drawing roller, prevent tow from skidding, improve drawing-off ability.Although the pressure roller that this drawing machine increases partly can prevent skidding, but owing to being linear contact lay between pressure roller and drawing roller, be then link friction with to-be-drawn material therebetween, frictional force is less, when stretching thing is chemical fibre be, be not that thickness is definitely identical by chemical fibre therebetween, by time therebetween, easily there is larger gap between pressure roller and drawing roller and cannot reach the object of pressing and increasing friction in chemical fibre simultaneously.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of very effective preventing and skids between chemical fibre and drawing machine, makes drawing machine reach the drawing machine of the stretching chemical fibre of stretching chemical fibre multiple object.
For achieving the above object, the utility model provides following technical scheme: the power set comprising frame, be arranged on the some drawing roller in frame and drive drawing roller to rotate, in frame, and the relative position being positioned at chemical-fibre drafting face in drawing roller is provided with some transfer rollers, transfer roller is provided with and presses belt driving and press belt rotation, press belt and chemical fibre pulling face fits tightly; Drawing roller and transfer roller synchronous axial system.
Clearance adopts technique scheme, during the work of this drawing machine, chemical fibre is successively by some drawing roller surfaces, pressure is increased by pressing belt, press belt with drawing roller with identical speed associated movement simultaneously, then be clamped in the pressure increase of pressing the chemical fibre between belt and drawing roller and being subject to, frictional force increases equally, chemical fibre can be prevented from and press between belt or drawing roller skidding, be arranged on the corresponding chemical fibre pulling face of corresponding drawing roller owing to pressing belt simultaneously, then press belt all to contact in face with chemical fibre and drawing roller, chemical fibre is made to be pressed on drawing roller completely and to press between belt, relative sliding can not be there is because part contact is insecure, ensure that chemical fibre reaches the object of draw ratio greatly.
The utility model is set to further: the width pressing belt is identical with the width of drawing roller.
By adopting technique scheme, pressing belt can be pressed all by the chemical fibre in drawing roller completely, prevents skidding.
The utility model is set to further: drawing roller is at least 1/3 of drawing roller lateral area with the area pressing belt contacts face.
By adopting technique scheme, drawing roller is with to press the contact surface area of belt larger, and fiber quilt drawing roller and to press belt compaction tensile position larger, can prevent to the greatest extent skidding.
The utility model is set to further: transfer roller with press belt and contact with each other surface and be provided with frosted layer.
By adopting technique scheme, the skidding that can prevent transfer roller and press between belt, and then ensureing to press belt and can rotate with transfer roller, finally making to press belt identical with drawing roller speed.
Compared with prior art, the drawing machine of the utility model stretching chemical fibre very effective preventing is skidded between chemical fibre and drawing machine, makes drawing machine reach stretching chemical fibre multiple object.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of the drawing machine of the utility model stretching chemical fibre is described further.
Embodiment one: as shown in Figure 1 to Figure 3, the power set comprising frame 1, be arranged on the some drawing roller 2 in frame 1 and drive drawing roller 2 to rotate, in frame 1, and the relative position being positioned at chemical-fibre drafting face in drawing roller 2 is provided with some transfer rollers 32, transfer roller 32 is provided with press belt 31 and can drive and presses belt 31 and rotate, press belt 31 and chemical fibre pulling face fits tightly, described drawing roller 2 and transfer roller 32 synchronous axial system, the preferred drawing roller 2 of the present embodiment is provided with seven, seven drawing roller 2 are divided into row's roller combination lower roll group, upper row's roller group has four drawing roller 2, lower roll group has three drawing roller 2, transfer roller 32 is provided with three, in the row's of being separately positioned on roller group rightmost drawing roller 2 both sides and directly over, pressing belt 31 is connection three transfer rollers 32 successively, and formed with drawing roller 2 and extrude parcel face, the width pressing belt 31 is identical with the width of drawing roller 2, drawing roller 2 is at least 1/3 of drawing roller 2 lateral area with the area pressing belt 31 contact surface.
During the work of this equipment, the surface of chemical fibre 5 along b direction successively through some drawing roller 2, pressure is increased by pressing belt 31, press belt 31 with drawing roller 2 with identical speed associated movement simultaneously, then be clamped in the pressure increase of pressing the chemical fibre 5 between belt 31 and drawing roller 2 and being subject to, frictional force increases equally, chemical fibre 5 can be prevented from and press between belt 31 or drawing roller 2 skidding, be arranged on corresponding drawing roller 2 corresponding chemical fibre 5 pulling face owing to pressing belt 31 simultaneously, then press belt 31 all to contact in face with chemical fibre 5 and drawing roller 2, make chemical fibre 5 be pressed on drawing roller 2 completely and press between belt 31, relative sliding can not be there is because part contact is insecure, ensure that chemical fibre 5 reaches the object of draw ratio greatly.
Further transfer roller 32 with press belt 31 and contact with each other surface and be provided with frosted layer, the skidding that can prevent transfer roller 32 and press between belt 31, and then ensure to press belt 31 and can rotate with transfer roller 32, finally make to press belt 31 identical with drawing roller 2 speed.
