Description

The spinning organ of rotation frame

The present invention relates to a kind of spinning organ of rotation frame, it has an isolator to be arranged in the cavity of rotor, and the yarn that is used for spinning separates with the single fiber that branch combs out, and the single fiber that these branches comb out is supplied to the slide wall of rotor by input channel.Input channel have an outlet be arranged on obliquely with wall that opening box is connected on, promptly in the housing of the spinning organ of relative isolator wall.

Such spinning organ has the isolator of several patterns in the cavity of rotor, the single fiber that is used for coming from opening box is guided the slide wall of rotor into, and prevent that these fibers are wrapped with the yarn of being produced when extracting spinning of producing, simultaneously, when these fibers are fed on the slide wall of rotor, increase its degree of stretching effectively.

The single fiber characteristic and the quality of putting on the rotor slide wall depend on the distance that isolator and input channel export on the one hand, on the other hand, the shape that depends on isolator, by its profile, the single fiber that branch is combed out places on the big of rotor or the slide wall than minor diameter.

That known isolator also has is fluted on its circumference, profile of tooth, needle-like or other brake apparatus, is used for mechanically its rear end being braked when fiber enters rotor, thus drawing of fiber or guide its termination into slide wall.

For obtaining straightening of fibers as much as possible, in rotor, adopted other solution to improve the motion that branch comb single fiber is crossed the embedding isolator, so that collide the friction effect that rotor slide wall place utilizes collision itself and produces at fiber, come the front end of accelerating fibers as much as possible, so that stretch fiber.

The solution of various known spinning organs, the slide wall of the rotor in its spinning organ and the axis of input channel constitute sizable angle, can not prevent that those are positioned at the single fiber that near the part of also walking out input channel thus of input channel outlet circumference is divided comb, flow back to against the isolator ambient air and to revolve, and can not prevent of the opposite direction deflection of these fibers at its normal traffic direction, therefore, partly overslaugh divide the depth of parallelism of the front end of comb single fiber.These fibers originally are to want stretching and place gathering face with stretching state, have not but both had air flow to be led by spacer, also do not produce friction effect between these fibers and gathering face.

In this area, known many solutions are used for making the fiber that places rotor to assemble face to reach high as far as possible degree of stretching, and thus, obtain higher yarn strength and lower yarn breakage rate.These solutions relate generally to the shape and the manufacturing of isolator, or increase the length that input channel arrives at the spinning machine slide wall.

The objective of the invention is to propose a solution, so that in the outlet of input channel and the part between the rotor slide wall, stable fiber head end from opening box, make it have the structure of height straight configuration, and suppress to be positioned at the circumnutation that input channel exports near the fiber of circumference, so that make it keep better extended parallelization.

Method of the present invention is, at the wall of isolator and form between the wall of input channel outlet, near this outlet and with respect to minute flow direction of comb fiber, the airflow deflector of one off-centre is provided, this deflector is made one transversal section, radially extending, and vacating a narrow free space, pointing to the slide wall of rotor.

Effect of the present invention particularly in, divide the front end of comb fiber, when it left input channel, by means of the airflow deflector of off-centre, therefore the state that its maintenance is stretched, was not subjected to any interference, arrived the rotor slide wall by isolator.

By way of example, illustrate one embodiment of the present of invention with accompanying drawing, wherein,

Figure 1 shows that spinning organ is fed to a sectional side view of rotor slide wall scope from opening box at fiber;

Figure 2 shows that rotor is analysed and observe and part isolator antetheca, in the input unit outlet and this mechanism's wall of opening box, export the axial view of the eccentric airflow deflector of the next setting.

Fig. 3 is an embodiment of eccentric airflow deflector for example;

Figure 4 shows that the cutaway view of spinning organ and eccentric airflow deflector, also show narrow space between rotor sliding surface, isolator and the eccentric air-flow local derviation;

Figure 5 shows that the isolator of making a stabilizer with eccentric airflow deflector;

Figure 6 shows that the wall of the opening box of making a stabilizer with eccentric airflow deflector.

Shown in Figure 1, spinning organ 17 has a rotor 2, be rotatably installed on the bearing 3, and quickening wall 6 excessively has a slide wall 4 to be located at the vicinity of gathering face 5.In the housing 1, be provided with an input channel 9, be used for minute fiber of comb is fed to rotor 2 from an opening box 7.Input channel 9 has its outlet on the wall 10 of opening box.Above this opening box, be provided with the isolator 11 of a closure or opening, be used for fiber 8 is guided to the slide wall 4 of rotor 2.

In axial view (Fig. 2), isolator shape is if any the dish of recess 12, be used for guiding the fiber 8 of branch comb, and the hole axially have one the outlet 14, be used for carrying resultant yarn 15, this yarn is extracted by the gathering face 5 of rotor 2, at housing 1(Fig. 1) in, pass a sprocket hole 16, be transported in the not shown extraction and coiler device.For producing negative pressure, rotor is equipped with as pore 13.

At isolator 11(Fig. 2,3 and 4) and the wall 10 of opening box 7 between, the direction of rotation of relative rotor 2, install an eccentric airflow deflector 18, shape is as one transversal section, and be positioned at branch comb fiber 8 input channel 9 rear portion outlet edge 19 near, divide the fiber 8 of comb to come from opening box 7.Diametrically, between the slide wall 4 and isolator 11 of rotor 2, this transversal section has constituted a narrow space 20, has been used for air current flow.One working edge 21 of eccentric airflow deflector 18 constitutes a diffuser 22 in this narrow space 20, is used for lateral airflow, to help putting in order and guiding the branch comb single fiber 8 that leaves input channel 9 to make it arrive spinning organ 17.Eccentric airflow deflector 18, form by transversal section, according to its position, can make the stabilizer 23 that has the wall of opening box 10 as, also can be made into as having a stabilizer of the isolator of making by a kind of solid material (stiff) 11.Yet eccentric airflow deflector 18 also can be made by elastomeric material, as rubber.

Above-mentioned spinning organ is pressed following work:

Cooperate pore 13, the rotation of rotor 2 has produced the negative pressure in the spinning organ 17, and therefore, a swabbing effect makes the single fiber 8 of branch comb from opening box 7, by input channel 9 and isolator 11, enters in the rotor 2.

Isolator 11, be located in the inside of spinning organ 17 on the passage of the branch comb single fiber of supplying by swabbing effect 8, guiding fiber 8 is to the slide wall 4 of rotor 2, on rotor, fiber slips over and quickens wall to gathering face 5, herein, fiber is paved into fiber band, converts yarn then in a well-known manner to, by a not shown device, pass through sprocket hole 16 carrying-offs by rotor 2, when minute head end of comb fiber 8 leaves input channel, the sphere of action that enters eccentric airflow deflector, this deflector makes fiber keep stretching value, and be not subjected to any interference, and, arrive the slide wall 4 of rotor 2 by isolator 11.

This stability of fiber 8, be due to the fact that, promptly, the eccentric airflow deflector 18 that embeds, by the air-flow around the outlet top isolator that suppresses input channel 9, prevented that fiber that input channel is left at this circumference place from circling round and stoped these pars fibrosa ground to the bias current with respect to its proper motion direction, this airflow flowing only is drawn towards narrow space 20.

In this narrow space 20, air-flow is further guided the working edge 21 that passes eccentric airflow deflector 18, because this air flows on the input channel, this deflector partly constitutes a diffuser 22, by being freed from opening box 7, by other air-flows of input channel 9, local derviation and the described air flow of acceleration.Because working edge 21 with narrow space 20 inhaled airs, just produces a lateral airflow in addition, promote to come from the branch comb single fiber 8 of opening box together, cross input channel, therefore, make these fibers in whole motion, keep stretching, arrive the slide wall 4 of rotor 2.
