Description

Top comb and the top comb support and the combing machine of combing machine are used to weave

Technical field

The present invention relates to a kind of top comb and top comb support of the combing machine that is used to weave, wherein top comb has a top pecten, can fix a pin bar on its matrix, wherein form a canned paragraph at the matrix upside, top comb can be fixed on the support by the geometrical clamp of this canned paragraph by means of the top comb support.

Background technology

The top comb of weaving combing machine is carried out one and is similar to oval-shaped motion, and treat that the carded fiber bar constantly stands the acceleration force that changes thus and owing to its embedding, this adds that the gravity of top comb itself causes top comb and the high mechanical load of the installed surface of top comb on the top comb support.This problem is very serious all the time, because the beat number of modern combing machine is constantly improving.

Common top comb is drawn by aluminium and forms, and therefore has the canned paragraph of dimensionally stable accurately, and the geometrical clamp of being made up of steel is owing to the process of hardening is not a dimensionally stable accurately on the contrary.This causes appearance point or linear load between canned paragraph and the geometrical clamp, and this causes very big wearing and tearing.

Summary of the invention

Setting out thus the objective of the invention is, and the top comb and the top comb support of the described type of design beginning make keeping reducing wearing and tearing greatly under the top comb condition convenient and fixing possibility promptly in this wise.

Realize by such method according to this purpose of the present invention, promptly establish a wearing course in the contact zone between top comb and top comb support, particularly have the plastics of good installation/ability to cure (Setzvermoegen) and excellent surface sliding capability.Also can adopt metal to replace plastics with respective performances.

Especially imagine, the top pecten canned paragraph integral body of top comb is made of plastics.

Can adopt thermoplastic polyurethane as plastics, its hardness range is 80 to 100 Durometer A hardness or 30-80 Shore D.Polyamide, particularly PA6.6 also are suitable.

This product has such advantage, promptly also has the vibration of inhibition, the performance of impact and bump except that outstanding ABRASION RESISTANCE.

If the canned paragraph of top pecten is made of plastics, it can make the section bar with a foot so, and it can be fixed on the top pecten by a kind of tubular groove.

Plastics also can be made the particularly coating of geometrical clamp of top comb and/or top comb support.

Top comb is equipped with plastic coating in the canned paragraph zone in a kind of preferred implementing form.Select the inboard of geometrical clamp also can be equipped with plastic coating as another kind.

Additionally or alternatively the matrix of top pecten and/or the conformable region on the top comb support also can be equipped with plastic coating.

It is contemplated that also that in order to reduce surface pressure and to reduce wearing and tearing geometrical clamp is than common width widen.

Imagination particularly advantageously is that the plastics of base are made the pressure sintering plastics with the high density polyethylene (HDPE) of pure ultra-high molecular mass.This plastics high abrasion has the little coefficient of sliding friction, reduces noise and resistance to chemical attack.

Reduce the additional of wearing and tearing that beginning mentioned or optionally possibility be, lightweight construction is made in top comb, particularly form by composite and/or light material such as magnesium.

The invention still further relates to a kind of top comb support of the combing machine that is used to weave, it has that a fixed area and that is used for top pecten supports pivotally is used for pushing down the geometrical clamp of the canned paragraph of top pecten, wherein by the present invention's imagination, the inboard of geometrical clamp and/or fixed area are equipped with plastic coating.Wherein particularly consider above-mentioned plastics.

The specific embodiment

Fig. 1 represents a top comb 1 by prior art, and it comprises a top pecten 2, comprises the pin bar 3 that is clamped in the row pin 5 between the two cover plates 4 having one on the top pecten.

Form one at top pecten 2 upsides and have the canned paragraph 6 that bends to the surface that is similar to 1/4 circle.This canned paragraph 6 can be compressed around the geometrical clamp 9 that axle 8 supports pivotally by one when top comb 1 is packed in the top comb support 7 of combing machine one side, and wherein an elbow 10 on geometrical clamp 9 ends is clamped on the interior seamed edge 11 of canned paragraph 6.This is illustrated among the local I II in Fig. 2 and 3 in more detail.

Can also see thus, though with the moulding of making accurate relevantly given canned paragraph 6, but it is different with the moulding of geometrical clamp 9, so geometrical clamp is fitted on the canned paragraph 6 in

point

12 and 13 place's point-like or wire, at

point

12 and 13 places because big wearing and tearing in advance appear in active force.

For fear of this wearing and tearing, imagine the employing thermoplastic polyurethane according to the present invention.

The inboard of geometrical clamp 9 is equipped with plastic coating 14 in the form of implementation of pressing Fig. 5 and 6.

Plastic coating 14 is coated in the upside of canned paragraph 6 in by the form of implementation of Fig. 7 and 8.

Whole top pecten 2 in pressing the form of implementation of Fig. 9, that is, all be equipped with plastic coating 14 no matter be matrix 18 or canned paragraph 6.

Canned paragraph 6 also has the fixed area 15 of top comb support 7 to be equipped with plastic coating 14 in pressing the form of implementation of Figure 10 to 12.

The canned paragraph 6 of top pecten 2 discord matrixes are made of one in by the form of implementation of Figure 13, but make the unit of plastic 14 of a foot 16 '.

Upside at top pecten 2 matrixes forms a kind of tubular groove (Kedernut) 17, unit of plastic 14 ' pin 16 can insert from the side in this tubular groove, can realize especially simply fixing here in this way.Because the overall elasticity of plastics and foozle irrespectively realize geometrical clamp 9 good large tracts of land and fit.

Can adopt that thermoplastic polyurethane or especially pressure sintering plastics form to add strength polyethylene with the pure ultra-high molecular mass high density be that the plastics of base are as plastics.Top pecten also can be made of plastics fully, and it can be strengthened/strengthen into composite material element or not have to strengthen and have a geometry that load is optimized here.
