Abstract
The utility model relates to a twist-resisting head comprising a body (3), wherein a through hole (4) communicated the upper end face and the lower end face of the body (3) is arranged in the center of the body (3), the upper end face of the body (3) is provided with a round boss (2) which is on the same coaxial line with the through hole (4), the outer diameter of the round boss (2) is smaller than the outer diameter of the upper end face of the body (3), the through hole (4) extends to the upper end face of the round boss (2), and the upper portion of the through hoe (4) is a big-end-up arc-shaped horn mouth. The twist-resisting head is low in end breakage possibility of slivers, high in spinning efficiency, and good in spinning quality.
Description
Technical field
The utility model relates to the open-end spinning technical field, is specifically related to a kind of resistance twist head that is used for rotor spinning machine.
Background technology
At present; Spinning technique mainly comprises rotor spinning and ring spinning; Rotor spinning be through a negative pressure in the revolving cup of high speed rotary and the cup accomplish fibre transportation, cohesion, and and, the twisting resultant yarn, rotor spinning is compared with ring spinning, it is short to have a technological process; Package capacity is big, output is high and characteristics such as labor productivity height, is domestic and international application spinning technique the most widely.
On rotor spinning machine; Adopting the main purpose of resistance twist head is the fricative false twisting effect through sliver in the revolving cup and resistance twist head; Turn on the yarn arm section (being the sliver of resistance twist head to one section of revolving cup collection surface) is increased, thereby can increase the power of getting in touch between yarn arm section and yarn, reduce broken end.At present textile mills reach the purpose that makes full use of resource and reduce production costs, and often adopt the just little and short fibers material of the leftover pieces of chemical fibre factory as raw material and since this type of raw material contain assorted big, short fiber content length high, fibrous body is short partially; The spinning difficulty is increased, add that this type of chemical fibre raw material fat content is higher, oil residue is more when rubbing with the resistance twist head; The probability that sliver produces broken end increases; Spinning efficiency is lower, and the sliver stripe shape is relatively poor, spinning quality.
Summary of the invention
The utility model technical problem to be solved is: it is lower to provide a kind of sliver to produce the broken end probability, and spinning efficiency is higher, and spinning quality is the resistance twist head preferably.
The technical scheme that the utility model is taked is: a kind of resistance twist head is provided; Comprise body; The center of said body is provided with the through hole that is communicated with body upper end and lower surface, and the upper end of said body is provided with the round boss with said through hole coaxial line, and the external diameter of said round boss is less than the external diameter of body upper end; Described through hole extends to the upper end of round boss, and the top of said through hole is up big and down small circular arc horn mouth.
After adopting above structure, the utility model resistance twist head is compared with prior art, and following advantage is arranged: owing on the upper end of body, be provided with round boss; The through hole that is located at body extends to the upper end of round boss, and during work, the sliver in the revolving cup gets into the resistance twist head through round boss; Because the external diameter of round boss is less than the external diameter of body upper end, when the sliver in the revolving cup was the diameter rotation at the external diameter with round boss, the sliver of rotation reduced than the area that contacts with the body upper end with the contact area of round boss to some extent; The friction of sliver and round boss reduces to some extent, and the grease that sliver remains in contact-making surface reduces, and helps the formation and the transmission of sliver turn like this; Reduce the probability that sliver produces broken end; Spinning efficiency improves, and the sliver bar shaped is good, and spinning quality is good.
As improvement, the curved surface of said arc transition is provided with along the equally distributed groove of circumference, and the false twisting effect that groove can strengthen yarn is set.
As further improvement, described groove is 6 ~ 8, is preferred embodiment, and is promptly in order to be effective, and it is also more reasonable that institute takes up space.
As further improving, the height of said round boss is 1 ~ 2 millimeter, and the diameter of round boss is 10 ~ 12 millimeters, is preferred embodiment, can reduce the whole volume of resistance twist head.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model resistance twist head.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1, groove, 2, round boss, 3, body, 4, through hole.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Like Fig. 1, shown in Figure 2, the utility model resistance twist head comprises body 3; Body 3 is the steel body of T-shape for the longitudinal cross-section; The center of body 3 is provided with the through hole 4 that is communicated with body 3 upper ends and lower surface, and the top of through hole 4 is up big and down small circular arc horn mouth, and the bottom of through hole 4 is up-small and down-big straight type horn mouth; The upper end of body 3 is provided with the round boss 2 with through hole 4 coaxial lines; The external diameter of round boss 2 is less than the external diameter of body 3 upper ends, and the upper end of through hole 4 extends to the upper end of round boss 2, and just through hole 4 is communicated with round boss 2 upper ends and body 3 lower surfaces.
In this example, the bell-mouthed curved surface of circular arc is provided with along the equally distributed groove 1 of circumference, and the quantity of groove 1 is 6 ~ 8; This example is 6; The height of round boss 2 is 1 ~ 2 millimeter, and just the distance between body 3 upper ends and round boss 2 upper ends is 1 ~ 2 millimeter, and this example is got 1.7 millimeters; The external diameter of round boss 2 is 10 ~ 12 millimeters, and this example is got 12 millimeters.
The utility model is in when work, and the sliver through the revolving cup rotational forming at first gets in the through hole 4 through the upper end of round boss 2, then along the bell-mouthed curved surface of circular arc through groove 1, draw from the bottom of through hole 4 at last.The present invention can reduce the broken end probability of sliver, and equipment operation efficient has mentioned 10%, improves spinning efficiency, and the sliver uniformity improves 30%, and spinning quality increases.
