The divisional application of the application for a patent for invention of the feed plate of the ribbon fibre-opening unit of end spinning machine ".
Technical field
The present invention relates to the feed plates of the ribbon fibre-opening unit for free-end spinning machine.
Background technique
The feed plate of ribbon fibre-opening unit for free-end spinning machine is exactly known and a large amount of for a long time
Quite at large illustrated in patent document with various different embodiments parts.
35 01 842 A1 of DE for example discloses a kind of ribbon fibre-opening unit, wherein generally cylindrical in shape, preferably open
The ribbon feed roller and matched feed plate of slot constitute the clamping zone for being fed for ribbon, wherein feed plate is can pivot
Turn the component part of the feed apron of bearing.The ribbon feed roller slowly rotated will be fed for fiber with constant conveying speed
Item (it is preferably temporarily stored in spinning bucket) feeding is set to plucker roller thereafter.It is fed for ribbon and goes to the road of plucker roller at it
The compactor being located on feed apron is first passed around on the way, and the compactor is before being fed for ribbon and reaching clamping zone, no
Only compress be fed for that ribbon and assigning is fed for that ribbon determines to being fed for advantageous shape.In addition, feed apron is closely
Clamping zone also have so-called fiber must supporting part, that is, the end regions of feed apron are constituted will process for plucker roller
, so-called fiber must bearing surface, which leads to plucker roller substantially straightly.However in this known feed plate,
Exposed larger wedge piece must be obtained between supporting part in clamping zone and fiber, this there must be negative effect to carded fiber.
103 51 365 A1 of DE illustrates a kind of feed plate, wherein fiber palpus supporting part is not linear, with
The shape of mating plucker roller matches.It means that fiber palpus bearing surface has concave shape, this is being combed in this feed plate
Fiber palpus is very well supported during reason.
Furthermore it is known that some feed plates and can in high volume use in practice, it is configured to two-part.?
That is such as the feed plate component of steel be fixed on the feed apron that pivotably supports (it be preferably designed to aluminium diecasting
And there is spill fiber palpus supporting part in end side) on, which constitutes together with ribbon feed roller and is fed for fibre
Tie up the clamping zone of item.
However the shortcomings that these feed plates, is not only in that their manufacturing costs height and in being fed for ribbon slideway region
Also there are seam points.Seam points of this set in the region between feed plate component and feed apron are easy by such as cotton
The pollution such as wax, honeydew.
Thus in the past it has been proposed that feed plate at least in the region for the fiber contacts for being fed for ribbon have hardening
, continuous sealer, which can prevent the dirt of stickiness from being adhered on feed plate.
This feed plate has for example explained in 40 08 884 A1 of DE.These known feed plates have main body,
The layer being made of ceramic materials is coated in main body as sealer.That is, when manufacturing feed plate known to these, it is first
It first passes through blasting treatment and makes clean main body roughening, followed by including by chrome green, silica and oxidation
The mixture of microcosmic short grained, the water base stirring of aluminium composition rinses main body.It is Celsius that workpiece is heated approximately at 500 after drying
Spend and execute the waterproof and heat treatment process of multi-step.The workpiece surface obtained in this way not only relative wear damage but also
Also there is only about 0.26 coefficient of friction, this greatly prevents the adherency of dirt.
However next on-the-spot test shows to be present in ribbon in the feed plate of coating in this way
Chucking power between feed roller and feed plate will lead to hardened surface as time goes by and be pressed into main body, this will cause seriously
Surface defect.
This defect for being known as eggshell effect by professional person is to improve the final cause of this feed plate.
Feed plate disclosed in 195 04 607 A1 of DE passes through ribbon feed roller and replaceable independent feed plate
The special tectonic mode of element, so that a possibility that pollution feed plate is reduced to minimum, but it is also impractical in practice.
In disclosed this feed plate, it is equipped with U-shaped feed plate element in feed plate clamping zone, is fixed on matched feed
To on curtain, feed apron itself constitutes the end side bearing surface of fiber palpus.It should be by accordingly in side in this feed plate
The too fast pollution of feed plate clamping zone is prevented to the cleaning device being arranged on ribbon feed roller.However it is produced in the knowledge
How do not specify in power document can prevent usually to particularly occur on the slideway for be fed for ribbon in feed plate element/be fed for curtain
Corresponding pollution in the seam points region of son.
