Background
Open-end spinning is a novel spinning technology which utilizes air flow to condense, twist and output fibers into yarn in a spinning cup which rotates at a high speed. The captured fibers can be thrown out by centrifugal force generated by high-speed rotation of the spinning rotor through cotton sliver fibers fed into the spinning rotor. The draw-off nozzle is fixed in the draw-off channel of the open-end spinning device and is used for guiding and deflecting the yarn made on the spinning rotor during the draw-off process.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Example (b):
referring to fig. 1 to 4, the present invention provides a technical solution:
a draw-off nozzle for an open-end spinning device, comprising:
a yarn drawing nozzle 1 arranged in the shield 2, the yarn drawing nozzle 1 is provided with an anti-abrasion sleeve 5 and a yarn drawing nozzle funnel 12 which can make the produced yarn 3 turn in the yarn drawing process;
a rotor 4 for moving the yarn 3 around the surface of the yarn withdrawal nozzle 1 in a crank-driven manner;
the draw-off nozzle funnel 12 comprises a yarn deflection area 1b consisting of an outer area 1c and an inner area 1 d;
the outer side area 1c and/or the inner side area 1d is provided with a contact part 6 for changing the surface-surface contact of the yarn 3 and the yarn turning area 1b into point-surface contact;
the atomizing part is located in the shaft hole 5a of abrasionproof cover 5 to be close to contact site 6, it is right yarn turns to district 1b, contact site 6 and through yarn 3 that the yarn turned to district 1b and contact site 6 and provides the tiny liquid drop and be used for the cooling heat dissipation.
As a result of the deflection of the thread 3 on the draw-off nozzle funnel 12, the draw-off nozzle shaft serves to fix the draw-off nozzle 1 in the housing 2 of the spinning device. The surface of the draw-off nozzle funnel 6 heats up strongly due to friction as a result of the uninterrupted contact with the yarn 3 moving around at high speed.
In the present invention, by providing at least one contact portion 6 on the yarn turning zone 1b, the surface-surface contact between the yarn 3 and the yarn turning zone 1b is changed to the point-surface contact. Since in the prior art, the face of the yarn 3 is in contact with the face of the yarn turning zone 1b when the yarn 3 passes through the yarn turning zone 1b, this is referred to as face-to-face contact or face-to-face contact. In the present invention, the contact portion 6 has a smaller size/volume/footprint than the entire yarn withdrawal nozzle 1 and the yarn diverting section 1b, and thus can be regarded as a particle of the yarn withdrawal nozzle 1 and the yarn diverting section 1 b. Therefore, when the contact portion 6 is provided, the contact between the yarn 3 and the contact portion 6 is point-to-surface contact or point-to-surface contact.
As shown in fig. 2 and 4, in particular, the contact portion 6 includes a body 6a, two sides of the body 6a have protrusions 6b, and a groove 6c for the yarn 3 to run is formed between the protrusions 6b and the protrusions 6 b. The groove body 6c is shaped like a v-21274, an arc groove or an inverted truncated cone. By providing the contact portion 6, the friction area of the yarn 3 can be greatly reduced when the yarn 3 passes through the contact portion 6, and the temperature rise due to intense heat generation by friction can be reduced. In order to avoid the influence of wear on the contact part 6 due to friction, the contact part 6 can still be made of a ceramic material with excellent wear resistance, but it can of course also be made of a metal material, preferably with the best possible thermal conductivity, and then, on the basis of the metal material, the inner part (not shown) of the draw-off nozzle funnel is made of a material with good wear resistance (in particular a ceramic material). Therefore, the contact portion 6 is less affected by the degree of limitation of the selected material.
In the invention, the groove body 6c is arranged, so that the yarn 3 can pass through the groove body 6c when being driven and wound by the rotor 4, on one hand, the heat generated by friction can be reduced as described above, on the other hand, the groove body 6c can limit the yarn 3 in a certain range during routing, the width of the groove body 6c is slightly wider than the diameter of the yarn 3, and therefore, the accuracy of a routing path can be ensured in the routing direction of the yarn 3 during high-speed winding. The contact part 6 is also provided with a connecting channel 1f, the connecting channel 1f is beneficial to dissipating heat generated between the contact part 6 and the yarn 3 due to the friction of the running thread, and the temperature of the contact part 6 is not too high. On the premise of not introducing gas into the inner channel 1e, small liquid drops sprayed by the atomizing spray head 7 can enter the inner channel 1e through the connecting channel 1f of the contact part 6, so that the heat dissipation of the yarn drawing nozzle 1 is realized, and the yarn drawing nozzle 1 is favorably kept at a proper temperature. And the inner diameter of the communicating passage 1f of the contact portion 6 is smaller than the inner diameter of the communicating passage 1f of the inner passage 1 e. This is done to introduce gas into the inner passage 1e, so that heat can be dissipated by friction between the contact portion 6 and the yarn 3, without affecting the routing of the two, and without affecting the heat dissipation of the small liquid droplets ejected from the atomizer head 7 to the area to be ejected.
Specifically, the atomizing part includes an atomizing nozzle 7. As shown in fig. 2 and 4, in the present invention, the atomizer 7 is adopted, so that distilled water, cold water or other suitable cooling liquid can be atomized by the atomizer and then sprayed to the contact portion 6 (and the yarn turning region 1 b) through the atomizer 7, heat generated by friction at the contact portion can be taken away, effective heat dissipation can be achieved, overheating can be prevented, and the rotating speed of the rotor 4 is not limited by the temperature of the yarn drawing nozzle 1 on the basis of not changing the yarn drawing nozzle 1 and the yarn drawing nozzle funnel 12 which are made of a better material with better heat conductivity. In order to enable the atomizer head 7 to dissipate heat from the sprayed area with the largest amount of atomized droplets, the atomizer head 7 is directed towards the contact portion 6 and tends to be parallel to the top tangent of the contact portion 6. In conclusion, the atomizing part can avoid the situation of friction overheating at the expense of reducing the running speed of the rotor 4 of the rotor spinning machine. Still exactly, the draw-off nozzle 1 part except draw-off nozzle funnel 12 that leads to because of the friction also has the uniform temperature, so the droplet after the atomizing evaporates more easily, play the heat dissipation to whole draw-off nozzle 1, and being infected with the droplet after the atomizing at yarn 3 that gives first place to cotton material, it can become compacter to be driven the winding by rotor 4, when learning fibre or synthetic fiber, yarn 3 dries fast easily, the region that is used for guiding the yarn on avoiding draw-off nozzle funnel 1 receives the pollution, and then can avoid taking place the condition such as disconnected yarn and yarn 3 impaired.
Specifically, the yarn guide device further comprises a flow guide part 10, a flow guide channel 11 is formed between the flow guide part and the yarn turning area 1b, and the micro liquid drops provided by the atomization part are guided into the flow guide channel 11. The guide part 10 comprises a guide cover 8 and a blowing head 9, the guide cover 8 is close to the yarn turning area 1b and is similar to the yarn turning area 1b in shape, and the blowing head 9 penetrates through the guide cover 8 and blows gas into the guide channel 11.
In the invention, as shown in fig. 2, when the yarn 3 is driven by the rotor 4 to wind, air or cold air can be introduced into the blowhead 9, so that the blown air can flow along the flow guide channel 11 to form an air flow a, and thus, small droplets sprayed by the atomizing nozzle 7 can flow from the inner zone of 1d to the outer zone of 1c, and thus, the whole yarn turning zone 1b and the contact part 6 can be continuously contacted with the small droplets, thereby leading to good heat dissipation effect. The air guide sleeve 8 can prevent the yarns 3 from being wound between the yarns 3 when the rotating speed of the rotor 4 is reduced, and can also prevent the influence of air flow generated by high-speed operation of the rotor 4 on the wiring accuracy of the yarns 3.
In particular, the thread drawing nozzle 1 has an inner channel 1e, the inner channel 1e is in air communication with the outside of the thread drawing nozzle 1 through a connecting channel 1f, and the contact part 6 also has the connecting channel 1f. The inner channel 1e is strip-shaped and extends towards the outside along the inside of the nozzle 1 and has a first mouth 1g, and the connecting channels 1f extend along the outside of the nozzle 1. In the present invention, as shown in fig. 2, the internal channel 1e is in the drawing nozzle 1 and is distributed in a similar manner to the current situation of the drawing nozzle 1, with only one first mouth 1g, preferably located in the inner part or in the outer part 1a. Air or cold air is introduced into the inner channel 1e through the first port 1g, so that cooling and heat dissipation of the yarn drawing nozzle 1 can be realized, and the yarn drawing nozzle 1 is protected.
In particular, the internal channel 1e is U-shaped, facing outwards along the inside of the drawing nozzle 1 and has a first mouth 1g and a second mouth 1h, the connecting channel 1f being distributed along the outside of the drawing nozzle 1 and being close to the external portion 1a. In the invention, as shown in fig. 3, unlike the above-mentioned first port 1g, the inner channel 1e is U-shaped and has a first port 1g and a second port 1h, and air or cold air can be introduced into any one of the ports, because the connecting channel 1f is distributed along the outer side of the yarn drawing nozzle 1, the heat dissipation point is biased to the outer side portion 1a, so that the yarn turning area 1b and the contact portion 6 can be cooled and dissipated preferentially, and the heat of other portions of the yarn drawing nozzle 1 can be dissipated by using the other port to dissipate heat.
When the yarn drawing device is used, the rotor 4 is used for enabling the yarn 3 to move around the surface of the yarn drawing nozzle 1 in a crank transmission mode, when the yarn 3 passes through the contact part 6, the contact between the yarn 3 and the contact part is point-to-surface contact or point-to-surface contact, the friction area of the yarn 3 can be greatly reduced, and further the temperature rise caused by violent heating due to friction can be reduced. In order to avoid the influence of abrasion on the contact part 6 due to friction, the atomizing nozzle 7 of the atomizing part is sprayed to the contact part 6 (and the yarn turning area 1 b), heat generated by friction at the position can be taken away, effective heat dissipation can be realized, the overheating phenomenon can be prevented, the blown gas can be led to flow along the flow guide channel 11 through the flow guide cover 8 of the flow guide part 10, an air flow a is formed, small liquid drops sprayed by the atomizing nozzle 7 can flow from the inner side area of the 1d to the outer side area of the 1c, the small liquid drops can be continuously contacted with the whole yarn turning area 1b and the contact part 6, the heat dissipation effect is good, air or cold air is introduced into the inner channel 1e through the first port 1g, the cooling and heat dissipation of the yarn drawing nozzle 1 can be realized, and the protection of the yarn drawing nozzle 1 is facilitated.
The invention, the remaining parts not described, are the same as, or known or realizable by the prior art and will not be described in detail here.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
