Description
Technical Field
The invention relates to spinning equipment and a spinning method, in particular to a spindle-free spinning device, a spindle-free spinning method and a spinning machine, and belongs to the technical field of spinning.
Background
The conventional ring spinning has been well developed for a long time, and its unique twisting winding manner is a very delicate design, but also causes many problems due to the design.
Firstly, the spinning speed is difficult to be further increased. The key of ring spinning is that the spindle actively rotates to drive the steel wire ring to rotate along the steel collar, and the steel wire ring adds one twist to the yarn every rotation and cooperates with the rotating spindle to complete the winding action. If the spinning speed is increased, i.e. the spindle speed is increased, the following problems are caused in the process: the friction between the balloon and the air is intensified, and the yarn tension is increased; the centrifugal force of the balloon is increased, and the yarn tension is increased; the friction between the steel wire ring and the steel collar is intensified, the heat is serious, and the abrasion is serious; input energy is largely consumed by losses, etc.
Secondly, the yarn tension fluctuation in the spinning process is frequent and can not be overcome. In actual spinning, the fiber strand delivered from the front roller nip is wound on a bobbin, and may experience the following fluctuation factors: the shape of the yarn guide hook, the airflow change near the balloon, the jumping of the steel wire ring, the friction coefficient change of the steel wire ring and the steel collar, the lifting of a steel collar plate, the stability of the rotating speed of a spindle, large, medium and small yarns and the like. Some influencing factors are determined by a ring spinning twisting winding mode and cannot be overcome at present, the final yarn quality and workshop production efficiency are directly influenced by yarn tension fluctuation caused by the twisting winding mode, and production cannot be carried out in serious cases.
Again, the yarn package capacity is small. The ring spun yarn is finally wound on a bobbin, the package capacity of the bobbin is limited by the diameter of a ring and the lifting stroke of a ring plate, so that the bobbin needs to be frequently doffed and replaced in the spinning process, although the full-automatic integral doffing technology is adopted at present, the doffing needs to be stopped, and the quality of the yarn before and after doffing is stable, so that the package capacity problem cannot be fundamentally solved.
Finally, twisting and winding are carried out simultaneously in the ring spinning process, and the twisting and winding are linked, so that the independent adjustment cannot be realized, and the accurate setting cannot be realized. The result of this is that the yarn twist cannot be accurately controlled at different spindle speeds, and requires multiple attempts or empirical adjustment, with large errors.
There are, of course, other problems with ring spinning, such as: the noise in the workshop is very high, and much flying occurs. In view of the above problems, there is a need for ring spinning, and several new spinning techniques have been developed in the last decades, but these new yarns have a yarn structure and properties that are significantly different from those of ring yarns, which is why ring spinning still has a large share in the market. Therefore, the invention aims to upgrade the ring spinning on the basis of not changing the yarn structure.

Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
Example one
The embodiment provides a spindle-free spinning device, as shown in attached figures 1 and 2, which comprises a roller drafting unit, wherein a yarn twisting unit 3 is arranged at the front lower part of a jaw (namely, the contact part of a front roller and a front rubber roll) consisting of a front roller 1 and a front rubber roll 2 of the roller drafting unit, a disc-shaped yarn guide cover plate 8 is arranged at the top of the yarn twisting unit, a yarn guide porcelain eye 7 is arranged in the middle of the cover plate, is in a right circular shape, is fixedly arranged on a pressure sensor, and has the function of detecting the tension of yarn in real time; the yarn twisting unit is a hollow cylinder, the outer wall of which is fitted with a pulley 12, the inner cavity 9 having three forms: the steel wire ring is cylindrical, conical or inverted bowl-shaped, the inner wall of the cavity is provided with a steel wire ring 10, and the bottom of the cavity is provided with a through hole 11; winding crank arms 4 are symmetrically arranged at two sides of the bottom of the twisting unit, and yarn guide hooks are fixedly arranged at the end parts of the winding crank arms; a yarn drum 5 is coaxially arranged below the yarn twisting unit, the lower end of the yarn drum is driven by a belt pulley, and the yarn drum can be replaced; the yarn drum 5 and the driving mechanism thereof are integrally arranged on the lifting platform 6, and the lifting platform controls the lifting stroke and the speed of the yarn drum.
Example two
A spindle-free spinning method specifically comprises the following steps:
after the roving is drafted by the roller drafting unit, fiber strands are output by a jaw consisting of a front roller 1 and a front rubber roller 2, pass through a yarn guide porcelain eye 7 in the middle of a fixed yarn guide cover plate 8, and then enter a steel wire ring 10 in the yarn twisting unit 3, each turn of the yarn twisting unit adds a twist to the yarn, and the twist is gradually transmitted to the jaw along with the increase of the twisting degree of the yarn, so that the fiber strands are gathered in a jaw spinning triangular area, and the yarn is gradually formed; the twisted yarn is finished yarn, is led out from a through hole 11 at the bottom of the yarn twisting unit, passes through a yarn guide hook at the end part of a winding crank arm 4 and is wound on a yarn barrel 5, the yarn twist is not changed in the winding process, and the winding speed is determined by the difference of the rotating speed of the winding crank arm and the rotating speed of the yarn barrel; in order to form a good yarn cylinder package and increase the package capacity, the yarn cylinder is driven by the lifting platform 6 to do reciprocating motion up and down, and the speed and the stroke of the reciprocating motion can be independently controlled, so that the yarn cylinder package can adapt to various specifications of yarn cylinders.
The yarn twisting unit 3 of the present invention is mounted on the belt pulley 12, only performs the rotary motion around the axis, the rotary direction can be clockwise or anticlockwise, but the direction is not changed in the winding process of a cheese, so that the yarn can not cause extra tension fluctuation in the yarn forming process. The air ring caused by yarn rotation in the twisting process is sealed in the internal cavity 9 of the twisting unit, so that the air ring is not easily influenced by external airflow and flying (short fibers flying with the airflow in the spinning process) on one hand; on the other hand, the shape of the cavity can also control the shape of the balloon so as to reduce the tension of the yarn. The balloon is a shape formed by that the yarn is driven to rotate by the twisting unit in the spinning process, and the middle section of the yarn is bulged outwards due to the relative fixation of the two ends under the action of centrifugal force, and the height and the diameter of the balloon influence the tension of the yarn. In the conventional ring spinning, as the ring plate is lowered, the height of the balloon is gradually increased, and when the weight of the traveler is lighter or the fineness of the yarn is smaller, the diameter of the balloon is increased, which may cause the tension fluctuation of the yarn. The yarn twisting unit adopts the inner cavity to control the shape of the balloon, so that the balloon is kept stable and unchanged in the spinning process, different cavity shapes are suitable for different spinning processes, and factors such as twisting speed, yarn twist and fineness can be comprehensively considered for selection. In addition, the yarn twisting unit is driven by the belt pulley to actively rotate, so that the yarn twist can be directly and accurately controlled through the rotating speed, the twisting speed can be greatly increased, and the spinning speed is further increased.
The yarn winding unit of the invention consists of a winding crank arm 4 and a yarn barrel 5, and the two are matched to independently and accurately control the yarn spinning speed. The yarn bobbin is driven independently by the belt pulley at the lower end, the rotating speed of the yarn bobbin is lower than that of the winding crank arm, and the speed difference between the yarn bobbin and the winding crank arm is determined by the yarn twist, the spinning linear speed and the winding diameter.
