Abstract

A kind of device (10,11,12) for capturing fiber slubbing in fleece lapper, it is made up of roller (10) and system (11,12), for capturing and again guiding unnecessary fiber.

Description

Catch yarn feeding device

Technical field

On the machine with the roll workpiece being formed fleece by chopped fiber, for shredding and homogenization, generally Using cylinder or the cylinder being provided with accessory, it is referred to as work-stripper roller (Arbeiter-Wender).See DIN 64118.

Background technology

In this machine, worker rollers is from cylinder or cylinder reeling fiber particularly fiber package, and is transferred to stripping Taking roller, stripper roller delivers this to again roller.If carrying the fibrous batt with slubbing, then at fibre to fleece lapper Dimension is through fleece lapper, and this slubbing is slightly elongated by worker rollers, but will not be completely eliminated.This fleece is uneven Even, it appears that " having clouding ".

Summary of the invention

It is an object of the invention to, propose a kind of device, it can improve the uniformity of fleece, and need less work- Stripper roller.

Although known fiber net lapper aspirates fibre down everywhere and is returned by these fibers, but prepares for Pilus Caprae seu Ovis It is well known that for machine, utilize burr-crushing hired roughneck along working width, bur to be destroyed from cylinder, then become waste material.For lid For plate carding machine, utilize revolving flats in large area from cylinder output chopped fiber and dirt, and flow to waste material.Manufacturing fibre During dimension net, these measures the most not yet use.The most in these methods, it is attempted to cut off unwanted part up hill and dale. With regard to the present invention catch yarn feeding device for, it is undesirable that fibre cutting, but conveying is for processing and realize the equal of fleece again Homogenize.

Catching a kind of specific implementation of yarn roller is to have the roller of different-diameter along the working width of roller.This is favourable , if it is desired to special moulding, such as edge are set to fleece relatively thin or thicker or the most thickening towards center, with Just subsequent treatment is improved.

The mode realizing similar effect can be to be not as cutting knife like that along working width according to pressing down section part of the present invention The most identical at a distance of the spacing of cylinder, but there is an edge, this border carries out the spacing of the roller of follow-up delivery to fiber Change along working width.This can also be carried out by the segmentation of cutting knife, and the spacing of each cutting knife section manually or Regulated by control member.

Accompanying drawing explanation

The present invention will illustrate by means of Fig. 1 and 2.

Fig. 1 exemplarily illustrates fleece lapper；

Fig. 2 illustrates uniform machinery, and it is also equipped with outlet roller.

Detailed description of the invention

Fig. 1 exemplarily illustrates fleece lapper.Fibrous batt 1 flows to licker-in by so-called feeding roller to 2 (Vorrei er) 3.Utilize 4 fiber conveyings of transfer roller to master rotor 7.Master rotor 7 is provided with worker rollers 5 He Stripper roller 6.Doffing (Doffer) accesses fiber and forms fleece.Unwinding device 9 takes off this fleece from doffing.

In this sketch, with a) representing the slubbing at fibrous batt feeding mouth, with b) representing at fleece lapper The slubbing being elongated in debatching.Worker rollers 5 and stripper roller 6 have elongated slubbing and have flattened.

Fig. 2 illustrates uniform machinery, and it is also equipped with outlet roller 10, the fiber that the capture of this outlet roller is unnecessary, and is sent to Collect position such as funnel 11.These fibers are sucked through aperture 12, and the equipment that is output flows to the most again form fibre The fiber stream of dimension batts.This outlet roller can also be installed at other roller or the cylinder of machine together with aspirating mechanism, such as, fill It is located at master rotor or work-stripper roller.Such as stripper roller can also be configured to outlet roller, its mode is, it is not By fiber conveying to corresponding master rotor 7, licker-in 3, but by fiber conveying to air-flow or conveyer belt.It is important that producing The web material output of raw inhomogeneities, those unnecessary fibers are along working width auto-returned, the most repeatedly present Send the fiber returned.Correspondingly, outlet roller is disposed adjacent to licker-in 3, or transfer roller 4 from licker-in towards master rotor or master Roller is arranged, or is disposed adjacent to master rotor 7, or is disposed adjacent to, thus fibre with worker rollers 5 or stripper roller 6 Dimension is taken off from these rollers, is then continued the major part of conveying fiber by the cylinder corresponding with outlet roller or roller.Sketch a) and b) It is shown in the fibrous batt before machine and the fleece after machine.

Before fiber arrives outlet roller, install the most somewhere relative to roller 4 adjustable pressing down section part 13.

Outlet roller advantageously has band neutral angle or the accessory of negativity anterior angle (Brustwinkel), the fiber taken off by This departs from outlet roller swimmingly without being wound around.Outlet roller turn to the roller that fiber taken off corresponding with it or cylinder Turn to identical.Its peripheral speed is 0.6-2.0 times of the peripheral speed of corresponding roller or cylinder, but the most right with it The roller answered or the peripheral speed of cylinder.

Claims

1., for being formed a device for the machine of fleece by fibrous batt, this machine has at least three conveying fiber Roller,
