Description
Technical field
The present invention relates to a top comb of a combing machine, top comb has mutually and is fixed on a tooth on the supporting member by spacing; Constitute a free slit between per two adjacent teeth.
Background technology
This top comb had introduction in some patents, for example DE-A1 19531605, EP-PS 351443 and EP-A1 557698.The arrangement of this top comb on nipper mechanism for example had diagram and explanation in EP-A1 619389.
The described combing machine of EP-A1-619389 for example, the fiber temples bar of combing must just carry out separation process on nipper is in the position of foremost and opening.This moment, nipper had the spacing of minimum to the gripping point of the detaching roller of its back.That stretch out from jaw and feed in this position by the web tail end of detaching roller through loopback through the web tail end of combing, then be sent to the gripping point of detaching roller by the forward travel of detaching roller.So promptly produce the superimposed of two tail ends or " welding ".To or do not gone out not by the web tail end by the further forward travel of detaching roller by the fiber separation of nipper machinery prevention.When the course of conveying of web tail end has entered gripping point between the detaching roller, and when carrying out the actual separation process, the web tail end arrives one and is fixed on the top comb pin on the nipper device or the centre of tooth.The fiber that choose by detaching roller this moment passes the vertical bar pin road of top comb, simultaneously cotton knot, impurity and other staple fibre is stoped to live.
When fiber during by top comb, the tooth root that staple fibre (approximately 12mm long till) may looping top comb comb cutter particularly, and form ribbon looping on single tooth in this position.This fiber that stockpiles on tooth mainly is so-called " floating fiber ", and they, can not be gripped by jaw line (detaching roller or feed roller) during by the combing of top comb card wire at fibrous material.
By continue after embedding circulation, this little band also can move and be fixed on this place by the direction of tooth root.
This little band can make other waste cotton be deposited on this zone, to the necessary zone that has free passage of combing work is diminished.
In order to remove this deposit, keep the abundant running of top comb, special-purpose cleaning plant is installed in suggestion, takes air-flow or mechanical mode to carry out the continuous or cleaning intermittently of top comb.
This class cleaning device has been published on some patents, and for example EP-PS 351443, and EP-PS 531740, DE-AS 2320200 and DE-A1 3815896.
This device that is specifically designed to the cleaning top comb also needs the device that adds, and wherein some device is that price is more expensive, and itself also puts aside foul easily.
Summary of the invention
Task of the present invention is that the tooth of top comb or top comb is done following design respectively, promptly stops fiber, the particularly staple fibre deposition on tooth to a great extent.
The invention provides a kind of top comb of combing machine, it has adjacent and is fixed in a tooth on the supporting plate, constitute a free slit between per two adjacent teeth, it is characterized in that, each tooth from its vertically (L) see provide two different sections (A1, A2), wherein the width of the section (A2) in the tooth root zone of adjacent teeth broadens gradually towards the tooth root zone, when it moves towards tooth root along described tooth with box lunch, can make the fibrous ribbon that is formed on the described tooth released.
By this comb structure, the first tooth section of broach can be designed to be suitable for best the combing operation with above-mentioned suggestion.The such design of conical tooth Duan Kezuo that another meets at the tooth root zone makes the deposition that does not form fiber laydown, particularly fibrous ribbon in this zone.The tooth of this shape for example can be used as the stamping parts manufacturing, and can also extrude convex tendon in the crown zone." tooth vertically " expression crown extends to the direction of tooth root, and the right angle points to the carriage direction of fiber.
Take the flank of tooth design at the broach rear portion of special suggestion, and corresponding tooth root width design in the second tooth section, can guarantee that the fibrage for the treatment of combing draws in the card wire fully in combing process, and prevent that staple fibre from stockpiling in the tooth root zone.
Position, angle by the rear portion flank of tooth of being advised in the first tooth section helps fiber web and is pulled in the card wire, and the obliquity of the respective teeth width of the relative tooth root of the rear portion flank of tooth in the second tooth section plays the effect of untiing to the fibrous ribbon that twines tooth.When the fibrous ribbon that forms when the tooth root direction moves, because facewidth degree is widened the respective corners position with the rear portion flank of tooth, and make ribbon released, and can automatically fall into the bottom, perhaps with continue after the combing process fiber web of being walked carry and be removed.
In addition, advise wide should the design of tooth root of the second tooth section greater than 3mm.The length of a staple fibre is approximately grown to most 12mm.By selecting a corresponding tooth root width, guarantee that the ribbon that does not produce staple fibre holds tooth root.Issuable ribbon can be automatically unclamps by the tooth root direction of having widened, and removes when it moves in the first tooth section like this.
For combing process, the length that the suggestion broach is first section is seen facing to throughput direction with the right angle, should be greater than second section length.So just can provide the tine length of largest portion for the carding process of reality, and remainder enough is used for carrying out cleaning.
Preferred manner is that the length of the first tooth section should be the twice of the second tooth segment length.
The anterior flank of tooth can be designed to arc or straight line.A kind of suitable form can make top comb be arranged to the detaching roller jaw line of close back as far as possible.The rear portion flank of tooth also can be designed to arc.
Suggestion in addition carries out the transition to the transition region of the second tooth section in the first tooth section, and this facewidth degree is seen facing to throughput direction with the right angle, is progressively broadening on the second tooth section end.It is released to help the fibrous ribbon that forms in the first tooth section like this, particularly when this fibrous ribbon when the tooth root direction that progressively broadens moves.
In addition, top comb tooth, particularly its first tooth section can also be designed to fiber and can shift from the straight line throughput direction when the card wire.
Can improve carding effect like this.
Shift from a rectilinear direction in order to obtain fiber, a kind of tooth with the convex tendon cross section can be provided in the first tooth section.This convex tendon can also play the attached scavenging action that helps (for example can referring to DE-PS 3937899) for cleaning.
In order between tooth fibre guide to be worked, it equally also works to combing intensity, can be with tooth cross section-from throughput direction-correspondingly design (for example referring to DE-A13146006).
