Abstract
The utility model discloses a novel drawing machine and belongs to the technical field of drawing devices. The novel drawing machine comprises a base and an airframe which is fixedly arranged on the base, wherein a first drawing roll group and a second drawing roll group are arranged in the airframe in parallel and staggered modes, an air cylinder and a compression roll support are fixedly arranged on the base, a compression roll is supported by the air cylinder and the compression roll support, and the compression roll is matched with a first drawing roll arranged in the second drawing roll group. The novel drawing machine has the advantages that the structure is simple, the design is reasonable, the slippage coefficient of tows on the surfaces of drawing rolls can be reduced through the parallel and staggered arrangement of the first drawing roll group and the second drawing roll group in the airframe and the control over the number of drawing rolls in the first drawing roll group and the second drawing roll group, the temperature rise of the tows caused by sliding friction can be reduced, consequently the position change of drawing points can not be affected, and the obtainment of fibers with uniform quality is facilitated.
Description
Technical field
The utility model belongs to the drafting system technical field, is specifically related to a kind of novel drawing machine.
Background technology
Drawing-off is to produce between the twice drafter.Before and after tow between the twice drafters, because the difference of drawing roller superficial velocity is stretched.Drawing roller in drafter is different from the drawing roller speed of another drafter, and by the drawing roller speed difference in two drafters, drawing machine is finished stretching.
The ratio of the draw roll superficial velocity of twice drafter is called draw ratio.In fact there is skidding in tow on the drawing roller surface, and the resultant draft multiple will be lower than its theoretical value.Therefore improve drawing roller to the grasping force of tow, can prevent from skidding, guarantee the stable of draw ratio.And improve drawing roller to the grasping force of tow, the most important thing is restrained stretching point position.In the production process, the factor that affects the drawing point position is a lot, except manufacturing condition, and the structure of the drawing roller in the equipment, quantity and different the stable of drawing point that also can affect that distribute.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to design the technical scheme that a kind of novel drawing machine is provided.
Described a kind of novel drawing machine, comprise base and the body that is fixedly installed on the base, it is characterized in that parallel the first drawing roller group and the second drawing roller group of being crisscross arranged in the described body, be fixedly installed cylinder and pressing roller holder on the described base, described cylinder and pressing roller holder support pressure roller, and described pressure roller matches with the first drawing roller in the second drawing roller group.
Described a kind of novel drawing machine is characterized in that described the first drawing roller group contains 4 parallel drawing roller.
Described a kind of novel drawing machine is characterized in that described the second drawing roller group contains 5 parallel drawing roller.
Above-mentioned a kind of novel drawing machine, simple in structure, reasonable in design, by parallel the first drawing roller group and the second drawing roller group of being crisscross arranged in body, and control the quantity of drawing roller in the first drawing roller group and the second drawing roller group, and can reduce tow at the coefficient that skids on drawing roller surface, also can alleviate the strand temperature that causes because of sliding friction and raise, affect the variation of drawing point position, be conducive to obtain the uniform fiber of quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-body; The 2-base; The 3-cylinder; The 4-pressing roller holder; The 5-pressure roller; 6-the second drawing roller group; 601-the first drawing roller; 7-the first drawing roller group.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of novel drawing machine comprises base 2 and the body 1 that is fixedly installed on the base 2.Parallel the first drawing roller group 7 and the second drawing roller group 6, the first drawing roller groups 7 of being crisscross arranged contain 4 parallel drawing roller in the body 1, and the second drawing roller group 6 contains 5 parallel drawing roller, amount to 9 drawing roller.Be fixedly installed cylinder 3 and pressing roller holder 4 on the base 2, cylinder 3 and the pressing roller holder 4 common pressure rollers 5 that support, pressure roller 5 matches with the first drawing roller 601 in the second drawing roller group 6.
During work, tow enters from the gap between the first drawing roller 601 and the pressure roller 5, then successively on the drawing roller of winding in the first drawing roller group 7 and the second drawing roller group 6, carries out drawing-off.
The utility model is by parallel the first drawing roller group and the second drawing roller group of being crisscross arranged in body, and control the quantity of drawing roller in the first drawing roller group and the second drawing roller group, can reduce tow at the coefficient that skids on drawing roller surface, also can alleviate the strand temperature that causes because of sliding friction raises, affect the variation of drawing point position, be conducive to obtain the uniform fiber of quality.
Shown in the above and the figure only is preferred embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
