Description
SPECIFICATION
A funnel for spinning preparation machines
The invention relates to a funnel for the compression and guiding of textile fibres in spinning preparation machines such as, for example flat cards, draw frames, combers and flyers for high processing speeds.
The funnel has at least one compression area.
Funnels for spinning preparation machines which are made of a metallic material are known from German Democratic Republic Patent
Specification No. 108 329 and are constructed with widely varying geometric embodiments in order to produce uniform cross-sectional compression. In order to produce these metal funnels considerable technical and technological expenditure is required in order to obtain a shape which is suitable from the point of view of flow technology and which is required for guiding and compressing textile fibres, in particular cotton and synthetic fibres, at high processing speeds. A further drawback of metal funnels is their relatively high weight.
In the case of a two-stage belt funnel, as shown in Federal German Republic Patent Specification
No. A/S 1137 982, the insert member of the funnel terminating in the conveyor direction of the fibres is of plastic. The Federal German Republic
Patent Specification No. O/S 2 254 957 also discloses a method of producing a roving funnel for a drawing frame made of antistatic plastic, steel or brass. Belt funnels made of plastic have the drawback that the wear resistance of polymer materials is generally not as great as that of metals. In the case of conventional high processing speeds this leads to considerable wear, in particular in the area of the greatest compression, at the belt funnel outlet.In addition, in the case of high processing speeds, large amounts of heat are generated as a result of high frictional forces, and an electrostatic charging of the fibre fleece or sliver to be compressed and the funnel of polymer material takes place.
As a result of the low heat conductivity of funnels of polymer material, the heat caused by friction is not suitably eliminated and a softening and destruction of the surface of the polymer material of the funnel at the critical funnel outlet zones takes place as a result of heating. The high electrical resistance of the plastics material also has a negative effect, as electrostatic charges caused by friction are not eliminated, which leads, in particular with high processing speeds and in the processing of synthetic fibres, to problems with guiding and compression of the fibres. The high heat of friction, the electrostatic charging of the fibres and the funnel and the escaping air lead, in addition, to irregularities in the sliver in the case of the known plastics funnels.
The object of the invention it to provide funnels for guiding and compressing textile fibres at high processing speeds, which funnels may be produced economically with little technical or technological expenditure, which have a long service life and which provide uniform compression of the sliver or fibre fleece.
In accordance with the invention the material of the funnel comprises a mixture of at least one polymer material with an inorganic filling material, preferably aluminium powder, copper powder or other metal powders which are good conductors of heat and electricity.
In this way it is possible to produce funnels which are constructed suitably from the point of view of flow technology in a simple manner and at the same time to remedy the previous drawbacks of plastics funnels.
The funnels of the invention have good heat conductivity and may therefore uniformly eliminate the heat of friction. As a result of their good electrical conductivity, they eliminate the electrostatic charges and reduce resistances during guiding and compression of the fibres. As a result of the incorporation of the metal filling material the wear resistance of the funnel is also increased. In an advantageous embodiment of the invention the funnel material consists of a mixture of polyamide, 1 5 to 45 per cent by weight of aluminium powder having a grain size of 20 to 300 zm and 3 to 5 per cent by weight of titanium dioxide.
Preferably, a metal sleeve is inserted in the belt funnel in the area of the fibre outlet. Another feature is that the funnel may have at least two compression areas, between which one or more air outlet apertures are disposed.
A further feature is that the funnel may comprise at least two individual funnels disposed consecutively, which are connected together with the incorporation of an annular air outlet aperture.
The individual funnels may be connected together by a snap connection.
For the purposes of the snap connection, the first individual funnel may comprise resilient ribs with lugs and stops onto which the consecutive funnel is pressed by means of the lugs of the ribs engaging behind its collar.
To help understanding of the invention, various specific embodiments thereof will now be described by way of example and with reference to the accompanying drawings, in which:
Figure 1 shows in cross-section a belt funnel with a metal sleeve,
Figure 2 is a cross-section through a funnel with two compression areas,
Figure 3 is a further cross-section through the funnel of Figure 2,
Figure 4 is a cross-section through a funnel in two parts,
Figure 5 is a further cross-section through the funnel of Figure 4.
The device for compressing and guiding a textile fibre fleece or sliver of Figure 1 comprises the funnel 1 , which tapers in the direction 2 of passage of the fibres and in which a metal sleeve 3 is disposed in the outlet area for the fibres. The material of the funnel 1 consists of the polymer material polyamide (Polyamide 6) and 1 5 to 45% by weight of aluminium powder with a grain size of 20 to 300 ,um, 3 to 5% by weight of titanium dioxide also being added to the material mixture in order to improve its mechanical properties.
Copper powder or any other metal powder may be used in place of the aluminium powder. It has been shown that if the proportion of aluminium powder is increased beyond 45% by weight, with the above-mentioned grain size, the polyamide matrix material is not able to bind the aluminium powder in a homogeneous manner and the surface roughness of the funnel 1 is therefore increased.
The metal sleeve 3 consists of stainless steel, brass or sintered materials and is designed to further increase solidity in the zones subject to the highest wear.
The funnel 3' of Figures 2 and 3 comprises a fleece guide 4 which tapers in the direction 2 of passage of the fibrins. It comprises two compression areas 5 and 6 between which air outlet apertures 7, in the form of slots, are disposed.
The funnels 1, 3' consist of a mixture of polymer materials such as, for example, polyamide, which are easy to shape and as a result of which an embodiment which is suitabie from the point of view of flow technology may be obtained, and metal powder designed to decrease the electrical resistance and to increase the heat conductivity as well as to increase the surface hardness. A mixture of 1 5 to 45% by weight of aluminium powder having a grain size of between 20 and 300 ym is used as a metal powder. In order to improve mechanical properties and for colouring, further materials such as, for example, titanium dioxide, may be added. Copper powder or like metal powders may also be used in place of the aluminium powder.
The fibre fleece is supplied to the funnel 3' and compressed by the conicity in the compression areas 5 and 6, the air contained in the fibre fleece being squeezed out. In order to improve the uniformity of the compression and to achieve higher speeds of passage of the fibres a relatively large portion of the compressed air is preferably evacuated via the air outlet apertures 7 in the direction of the arrow 8. In the subsequent compression area 6 the fibre fleece is further compressed to form a sliver.
As a result of the material used, and in particular as a result of the addition of metal powder, it is ensured that electrostatic charges caused by the guiding and compression of the fibres as a result of friction between the fibres, and between the fibres and the funnels 1, 3', are eliminated via the funnels 1 and 3' themselves.
In accordance with Figures 4 and 5, the funnel 9 consists of two individual funnels 10 and 11 disposed consecutively which both taper in the direction 2 of passage of the fibres. In this respect the individual funnel 11 disposed in the second position with respect to the direction of passage may also, in particular cases, have a cylindrical bore instead of the longitudinal slot 1 3 illustrated.
The individual funnels 10, 11 are disposed such that an annular space having a cross-section which is identical or different over the periphery is produced, which space forms the air outlet aperture 14. The fastening of the second individual funnel 11 to the first individual funnel 10 is provided by the snap connection 12 illustrated. The resilient polymer material, of which the individual funnels 10, 11 for the most part consist, enables the collar 1 5 of the funnel 11 to engage behind the lugs 1 6 disposed on ribs 1 7 of the first funnel 10 and as a result of the lugs 16 and the stops 1 8 provided on the first funnel 1 C, the second funnel 11 is fixed in position.The individual funnels 10 and 1 f consist of the same material as the funnels 1 and 3' described above and shown in Figures 1 to 3.
The fibre fleece is suppiied to the device and compressed by the conicity of the first funnel 10, wherein the air still contained in the fibre fleece after the first compression is partly discharged from the air outlet aperture 14 disposed between the two funnels 10 and 11 after the discharge of the fibre fleece from the funnel 10. Further compression may be carried out in the second funnel 11 without leading to defects, for example in the form of fibre obstructions and irregularities, in the sliver discharged from the second funnel 11.
The above described funnels have the advantages that the resistances present during compression, which are produced by friction, electrostatic charging, heating the air escaping from the sliver during compression, in the case of high processing speeds for the fibrous material, are eliminated.
