Description
Technical field
The present invention relates to a kind of Yarn resistant twisting head (Fadenabzugsd ü se) that is used for open end spinning apparatus.
Background technology
The Yarn resistant twisting head that is used for open end spinning apparatus is prior art for a long time, and known different forms of implementation is arranged.
The common problem that exists in open end spinning apparatus is, the true sth. made by twisting of the yarn that rotation imported by rotor enters into the yarn that is forming unevenly.
In other words, the true sth. made by twisting of yarn securely is deposited on the yarn line segment between the yarn exhaustion mechanism that was in Yarn resistant twisting head and open end spinning apparatus at that time.
In contrast, yarn is true twists with the fingers in the yarn line segment that often only imported to by halves especially before Yarn resistant twisting head.
Because the low especially yarn twist in the yarn line segment that exists between rotor groove and Yarn resistant twisting head plays bad especially influence for the spinning stability of open end spinning apparatus, people had developed the Yarn resistant twisting head that is provided with special surface structure in the past.Can improve the friction between the yarn of Yarn resistant twisting head surface and rotation by this preferably coarse surface texture, and on the yarn line segment that is forming, twist with the fingers a kind of so-called false twisting also stacked except yarn is true with this.
Because this false twisting extends in the yarn line segment that is present between rotor groove and the Yarn resistant twisting head, so a corresponding surface texture on Yarn resistant twisting head makes the spinning stability of the effective open end spinning apparatus of this proof improve.
Aspect structural design, material or surface texture, known a large amount of Yarn resistant twisting head that different forms of implementation is arranged.
For example DE-OS 25 44 721, DE 33 44 741A1 or EP 0 422 615 B1 have described Yarn resistant twisting head, and they have groove on the position of yarn Lead-In Area.
According to DE-OS 25 44 721, Yarn resistant twisting head is made by a kind of oxide ceramic material in this case, and has the roughness height of 0.2 to 0.7 μ m on the position of yarn importing funnel.
In addition, go back arrangement of grooves in the zone of yarn feeding, this groove can have different slot aperture angles.
The Yarn resistant twisting head of describing in DE 33 44 741A1 has a yarn removable, that also next hardened by the steel plate drawing and imports funnel.
This yarn imports funnel in this case or have groove or a lobed indent.
In this case, this groove also is positioned in the structure of two annulars, and this structure is arranged one by one along the yarn traffic direction.
EP 0 422 615 B1 relate to a kind of Yarn resistant twisting head, and this Yarn resistant twisting head has groove in the position in the zone that yarn imports, and pull out at the yarn of Yarn resistant twisting head and to have projection in the passage.
This groove can improve the spinning stability of open end spinning apparatus in this case, and the projection of pulling out in the passage at yarn is used to produce the yarn of special napping.
By CH-PS 535 294 known a kind of Yarn resistant twisting heads, this Yarn resistant twisting head not only has the groove of annular on lural position in addition, and has the groove of at right angles arranging with these annular grooves.
That is to say that the groove of in this Yarn resistant twisting head difference being arranged carries out overlapping, and form a plurality of supportings relatively initiatively for the yarn of rotation.This known Yarn resistant twisting head does not prove effectively in practice, is not admitted on market.
By spinning stability above-described, that Yarn resistant twisting head be called " groove is twisted with the fingers head " in professional range can improve open end spinning apparatus usually slightly, yet the improvement of spinning stability in this case makes the yarn qualities that can obtain pay a price at least in part.
The contact open end spinning apparatus, the certainly also known for prolonged period of time Yarn resistant twisting head that on the regional position of yarn feeding, has a kind of spiral yarn shaped structure.
For example DE 37 07 526 A1, DE 42 24 632A1 or EP 0 220 546 A1 relate to the Yarn resistant twisting head of this structure.
Here this spiral yarn shaped structure can be for example as in DE 37 07 526A1 or EP0 220 546 A1, describing, projection by lath or convex shaped constitutes, and whole yarns that this projection is preferably in Yarn resistant twisting head feed the place that begins that the yarn that extends to Yarn resistant twisting head on the zone is pulled out passage.
In Yarn resistant twisting head, in addition connect twisting stagnation element (Drallstauelement) in the back with the projection that favours the yarn traffic direction according to EP 0 220 546 A1.
A kind of Yarn resistant twisting head with spiral yarn shaped structure has also been described in DE 42 24 632A1.
This Yarn resistant twisting head here have spiral yarn shaped extension, along the plane of yarn traffic direction, this plane is used to produce the yarn guide position and ground, angle of inclination is arranged.
In the Yarn resistant twisting head of describing in front, in professional domain, be called " screw line is twisted with the fingers head ", yarn slides when pulling out through spiral yarn shaped structure protruding, wherein the direction of helix structure is so selected, promptly on the corresponding direction of rotation of yarn, on the yarn line segment that is forming a thrust assembly along direction work towards the rotor groove.This thrust assembly causes true sth. made by twisting of the yarn that imports by rotor to make that at least in part the position of leaving between rotor groove and the Yarn resistant twisting head is hindered.
In other words, use " screw line is twisted with the fingers head " of so design can be opposite with Yarn resistant twisting head with smooth surface, the higher twist of inhibition in the yarn line segment before Yarn resistant twisting head, and therefore the broken yarn quantity that occurs in spinning process is slightly descended, wherein the yarn qualities that is obtained is fine usually.
Although " screw line twist with the fingers head " compared with so-called " groove is twisted with the fingers head " and obtained yarn quality preferably usually, yet the shortcoming that should " screw line is twisted with the fingers head " has is that an obtainable spinning stability often can not be satisfied fully.
For example in DE 197 38 382 A1, describe a kind of like this screw line/groove and twisted with the fingers head.
In this known Yarn resistant twisting head, arrange that on the position of inlet a kind of spiral yarn shaped being used to suppresses the true structure of twisting with the fingers of yarn; In addition, groove is positioned at yarn and pulls out on the inlet position of passage.
Yarn resistant twisting head according to DE 197 38 382 A1 has proved effectively in practice, this explanation, by means of this Yarn resistant twisting head can be especially when spinning cotton, when spinning the polyester/cotton mixture, all produce and have high-quality yarn.
Certainly this foregoing, proving effective screw line/groove, to twist with the fingers the manufacturing of head bothersome especially.
In other words, need a kind of more complicated and all expensive especially instrument in order on the inlet position of Yarn resistant twisting head, to make spiral yarn shaped structure.
Shortcoming in these Yarn resistant twisting heads is in addition, this spiral yarn shaped structure flows out towards the edge of Yarn resistant twisting head, and this causes when the spinning yarn in the groove at rotor to form the zone constantly changing with distance between the spiral yarn shaped structure that is used to suppress the true sth. made by twisting of yarn.
