Abstract

A circular comb includes a base body (1) and a combing cloth 3 thereon. The points of the combing cloth (3) are tilted toward the front end of the base body (1) and the free ends thereof form a cylinder surface (Z). It also has a means for covering at least a part of the height of combing cloth points. For example, an introduction rail (7) is arranged at a smaller distance (a) than the height of the points in the radial direction of the combing cloth (3) from the cylinder surface (Z). The edges of fibers undergoing the combing with the half comb only partially receive the engagement with the points of the combing cloth (3) at the forefront end by the rail (7). Thereby, the points of the front combing cloth (3) do not undergo severe friction and the life of the half comb can be prolonged.

Description

Be fastened on the circular comb sheet on the circular comb roller of comber

The present invention relates to a circular comb sheet that is fastened on the circular comb roller of combing machine, it has a matrix and is fixed on the combing card clothing that has needle point on the matrix, and the needle point free end is positioned on the face of cylinder and tilts to the front end of matrix.

Such circular comb sheet is fastened in combing machine on the circular comb roller that rotates continuously, and being used for must the Cong Jinhang combing to the fiber that is contacted by nipper on circular comb sheet.Here always at first enter fiber and must can be subjected to certain wearing and tearing especially in card clothing tip clump, close matrix front end.This wearing and tearing will cause the variation of combing process gradually and finally must change circular comb sheet.

The objective of the invention is to improve the service life of foregoing circular comb sheet.

Be used for reaching the circular comb sheet of the present invention of this purpose, it is characterized in that covering at least in part the height at top card clothing tip with a kind of device, make top card clothing tip enter fiber must when clump not exclusively contact must clump.

Owing to the most advanced and sophisticated and incomplete contact fiber of top card clothing palpus clump, it is corresponding less therefore to wear and tear.

Be preferably in circular comb sheet matrix front end one introducing guide rail is set, there is a distance on it and the described face of cylinder.This distance is less than or equal to the height near the card clothing tip of front end.Introduce guide rail by means of this, the card clothing tip of close matrix front end always contacts the sub-fraction of fiber palpus clump at work, and it is corresponding less therefore to wear and tear.

Introduce guide rail and also be subjected to some wearing and tearing certainly at itself this respect, but variation that these wearing and tearing can produce combing process hardly.Be fixed on the matrix replaceably by preferential method if introduce guide rail, just can replace as a kind of comparatively cheap parts.

Introduce guide rail and can be fixed on the distance of regulating the above-mentioned face of cylinder of introducing guide rail distance on the substrate in adjustable mode, thereby must clump be regulated by the intrusion degree at the card clothing tip of close matrix front end according to fiber, for example regulate in order to adapt to the weight for the treatment of the combing cotton-wool.

Now it is as follows with reference to the accompanying drawings embodiments of the invention to be elaborated, wherein:

Fig. 1 represents to be fixed on the longitudinal section skeleton diagram of the circular comb sheet on the circular comb roller of comber.

The enlarged drawing of end fragment before the circular comb sheet of Fig. 2 presentation graphs 1.

Fig. 3,4,5 and 6 respectively represent the version of part shown in Figure 2,

Fig. 7 represents the partial view watched from Fig. 6 right side.

Fig. 1 represents a circular comb sheet that has matrix 1, among its mat figure not the fastening bolt of expression be fixed on the circular comb roller 2 of combing machine.Circular comb roller 2 rotates around its axle continuously with the clockwise direction of Fig. 1 when combing machine is worked.On the fan-shaped excircle of the cylinder of matrix 1 one then a ground 4

combing card clothing

3,4,5 and 6 are housed, towards the front end V inclination of matrix 1, and the needle point free end is positioned on the face of cylinder Z needle point of combing card clothing with respect to radially for.

Be provided with one on the front end V next door of matrix 1 and introduce guide rail 7, it extends near till the Z of the face of cylinder.Introduce between guide rail 7 and the face of cylinder Z apart from the needle point radial height h of a (Fig. 2) less than the close front end V of the combing card clothing 3 in foremost.Apart from a approximately height h 5～25% between, numerical value is advisable with 0.3～0.5mm.So, introduce the major part that guide rail 7 has covered top card clothing tip height h from the direction of motion at card clothing tip.Therefore can make by the top needle point of fiber palpus clump F (Fig. 1) some card clothing 3 that is combed for the treatment of combing on the circular comb sheet of nipper 8 contacts in rotation to contact, thereby these top card clothing points wear seldom.

Introducing guide rail 7 mat bolts 9 is fastened on the matrix 1 in removable mode.Bolt 9 passes a slotted hole 10 of introducing on the guide rail, therefore unclamp after the bolt 9 can by the direction of double-head arrow P regulate change apart from face of cylinder Z apart from a.

In order to make the wearing and tearing of introducing guide rail 7 remain on minimum level, preferably through quenching or the coating of a rub resistance being set, it also can be made by hard metal for it.

In pressing the version of Fig. 3, introducing guide rail 11 is that mat bolt 12 is fastened on the front end section of matrix 1 replaceably.Introducing guide rail 11 can not regulate on matrix 1.About introducing the distance between guide rail 11 and the face of cylinder Z, still effective in the explanation described in Fig. 1 and Fig. 2.Equally, introducing guide rail 11 preferably passes through quenching or coating or is made by hard metal.

In pressing the version of Fig. 4, introduce guide rail 13 and be by quenched or through coating or form by hard metal cylinder, be fixed on by method on the preceding end fragment of matrix 1 such as cementation.

In pressing the version of Fig. 5, to introduce guide rail 14 and be by on the preceding end fragment of matrix 1.1, processing and constituting with the protuberance branch that matrix 1.1 forms one, it preferably scribbles the coating of rub resistance.Here described the same with the front, introducing between guide rail 14 and the face of cylinder Z also is needle point radial height h less than top combing card clothing 3 apart from a.

Press the version of Fig. 6 and 7, the introducing guide rail is not set before the card clothing tip up front.In this mode, top card clothing tip height is partly covered, and just the space A (Fig. 7) between these card clothing tips is partly filled by a kind of material M.Therefore the fiber that wherein has the card clothing tip to enter must only be contacted by top card clothing tip by clump partially.Shock surface to fiber palpus clump increases to some extent simultaneously.Top card clothing tip in bottom section owing to the side collapse that causes of wearing and tearing can prevent by packing material M.Packing material can be as shown in the figure with the mode that tilts towards the outer surface of matrix 1 backward attenuate suitably.
