Background technology
A kind of Spindleless spinning machine that is fixed in the pressure roller on the rocking arm that has is disclosed by prior art DE 3630256A1.In this piece open source literature, the part of Spindleless spinning machine has only been described, because it only relates to the driving and the supporting of rotor.The document is not clearly mentioned the rotor shell that yet has to be under the negative pressure, and this rotor shell can link to each other with negative pressure source by negative-pressure pipeline.But obviously, the running for shown device must be provided with such rotor shell.The outward appearance of this rotor shell for example can be as DE 19841406A1 attractive in appearance as shown in Figure 1.
The shortcoming of known embodiments is for negative-pressure pipeline being placed in the rocking arm next door that can swing, need occupy a lot of structure spaces in Spindleless spinning machine.
Summary of the invention
The objective of the invention is to optimize the structure space utilization of Spindleless spinning machine inside.
The inside that this purpose is passed the axle of a bearing roller rocking arm by a part that makes negative-pressure pipeline is solved.
By passing the inner negative-pressure pipeline of axle, originally also to pass the negative-pressure pipeline of Spindleless spinning machine and can cancel, thereby save structure space on the whole.Advantageously, although have enough free cross sections to be used for the diameter that negative-pressure pipeline must enlarge described axle, generally speaking still saved structure space in order to make in the described axle.Because this dual-use function of described axle, the overall structure of whole Spindleless spinning machine is obviously simplified.On the whole still less, and the part of this band corner angle always can build up of dirt and dust with the part of corner angle.Except polluting still less, the also easier cleaning of this Spindleless spinning machine.
According to design of the present invention, advantageously, in negative-pressure pipeline, there is at least one the unnecessary air in the negative-pressure pipeline can be released by this hole by pressure roller is arranged the hole of opening from tangential belt.When spinning process interrupted, pressure roller lifted from tangential belt, and unnecessary air-flow reduces the negative pressure in the rotor shell, thereby can make easier the opening of cover piece of sealing rotor shell.Preferably can apply negative pressure to another pipeline by the hole in the negative-pressure pipeline, the inlet of this pipeline is corresponding with the position to be cleaned of Spindleless spinning machine.Therefore these unnecessary air-flows can be used for the gdna contamination of cleaning gas tream formula spinning apparatus.This position for example may be the cod district of rotor.
The enlarged-diameter of described axle has the advantage of improving the rocking arm supporting.Described axle in known Spindleless spinning machine normally diameter be the axle of 15 millimeter magnitudes.Preferably, the diameter of described axle is at least 20 millimeters, especially about 25 millimeters.After external diameter enlarged, the frictional force in the bearing caused bigger moment of friction on rocking arm.This moment of friction is inevitably swung because of driving belt fast turn-around pressure roller has positive role.The moment of friction that increases plays damping action, and the amplitude of oscillation of pressure roller is reduced.
According to another kind of design, can further improve the damping of rocking arm by other elements.Can apply certain frictional force in addition at the supporting position of rocking arm, damping action is played in the oscillating motion of this frictional force brake rocker arm thus.This can realize by spring-loaded friction element, perhaps also can realize by directly adding the very high fluid of viscosity in the gap between rocking arm and axle.
Other advantages of the present invention and feature provide by following description to embodiment.
Description of drawings
Fig. 1 shows the side view that dissects according to the part of Spindleless spinning machine of the present invention;
Fig. 2 shows the view that Spindleless spinning machine shown in Figure 1 dissects along section II-II.
The specific embodiment
Spindleless spinning machine 1 shown in Fig. 1 and 2 has a rotor 2, and this rotor comprises a cup axle 3 and a rotor dish 4.Rotor dish 4 is fixed on the cup axle 3 not rotatable.During work, rotation in the negative pressure cavity 5 of rotor dish 4 in rotor shell 6.Rotor shell 6 links to each other the negative pressure in this negative pressure source generation negative pressure cavity 5 by a negative-pressure pipeline 7 with not shown negative pressure source.
Rotor 2 is bearing in its cup axle 3 in the triangle space 8 of two supporting disk pairs 9, can drive by the tangential belt 11 that passes spinning machine along arrow A.Here, each supporting disk pair 9 comprises two supporting disks 10 with the known manner supporting.In the course of the work, tangential belt 11 is pressed against on the cup axle 3 of rotor 2 by pressure roller 12, thereby drives the cup axle.When work stopped, pressure roller 12 can lift from tangential belt 11.Pressure roller 12 is fixed on the rocking arm 13, can freely rotate.Rocking arm 13 is bearing in the Spindleless spinning machine 1 on the fixed axle 14, can swing along swaying direction B.Axle 14 borings, this hollow part contains the part 15 of negative-pressure pipeline 7.
Axle 14 maintains static on the framework 16 of Spindleless spinning machine 1.This point for example can be by being pressed into or being threaded realization.Can be in the said fixing position of axle 14 on framework 16 not illustrate in scheming but known mode itself disposes a drum device, this drum device makes tangential belt 11 alignment of axle 14 in can turning round relatively.Supporting on axle 14 does not need the especially little bearing that rubs for rocking arm 13, because high bearing friction helps producing big moment of friction on rocking arm 13, thus the swing that occurs in the decay operation process.High moment of friction realizes by at least 20 millimeters major diameter D of axle 14.Preferably approximately 25 millimeters of external diameters.
Rotor shell 6 has an open front 17, and by 19 sealings of a cover piece, this cover piece can be arranged so that keep in repair around swinging axle 18 in the operation process.A ribbon fibre-opening unit having 20 that is used for ribbon is housed on cover piece 19, and it is by a unshowned opening roller opening fiber bar.By the negative pressure in the rotor shell 6, the fiber of being got ready by ribbon fibre-opening unit having 20 in operation process is transported to the inside of rotor 2 through a fiber feeding passage 21.The fiber that infeeds in the rotor 2 accumulates a fibrous ring in the fiber collector groove 22 of rotor 2.The yarn 23 warp yarn unwinding in known manner passage 24 that forms in fiber collector groove 22 is drawn and is fed in the unshowned doff device along unreeling direction C.In order to seal negative pressure cavity 5, a sealing ring 25 can be set between rotor shell 6 and cover piece 19.
