Definitions

  • the invention relates to a working element on a fiber-processing machine having at least one roller, wherein the working element of the roller is arranged at a distance from one another.
  • the working element extends over the entire working width of the roller, wherein a part of the working element is formed as a suction channel.
  • the working element has at least one Ausscheidemesser and another carding or covering. Between the carding or covering and the Ausscheidemesser is an opening with an ejection distance. The opening connects a space between the working element and the roller with the suction channel.
  • the invention also relates to an associated method for adjusting the ejection distance and a closure element for use in apparatus and method.
  • Spinning preparation plants use machines, such as cleaners or carding machines, which contain various working elements for the cleaning, sorting, opening, carding, etc. of the fibers to be processed.
  • the various types of fibers are processed, including cotton fibers or man-made fibers or mixtures thereof.
  • the parts or fibers are usually separated from the Ausscheidemesser of a rotating roller.
  • an opening in the working element is provided against the drum before the Ausscheidemesser, the width of this opening is called the ejection distance. After the separated parts have passed the knife, they are fed to a suction and conveyed away.
  • a setting of the ejection distance, the gap between knife blade and safety rail is complex, because on the one hand the accessibility of the screws is given only after opening the vacuum Saugcroabdeckung and on the other hand, the adjustment must be made via several screws, which is a constant check the setting by quantitative measurement necessary power.
  • Another cleaning element with a Ausscheidemesser discloses the font DE 39 02 204 A1 , Therein, the ejection distance is determined by the distance between the knife blade and the upstream element. At the back of the upstream element, a guide element is mounted, which can be pivoted into the ejection distance and thereby changes the size of the ejection distance.
  • the guide element is arranged to be movable, which can lead to an undesired adjustment during operation.
  • the shape of the element must also be ensured for a longer construction by a correspondingly complex construction. Due to the fact that guide element and knife blade are not arranged on the same cleaning element, the accuracy of the adjustment is impaired by the independent attachment of the individual cleaning element to the machine.
  • the European patent application EP 0 388 791 A1 also discloses a device for removing dirt with the aid of a knife blade, which allows an adjustment of the ejection distance.
  • the setting of the separation gap between the knife blade and the upstream carding element is carried out by adjusting screws.
  • the screws are freely accessible in the disclosed embodiment, without a part of the device must be dismantled. The complex adjustment due to several distributed over the length of the working element screws remains, however.
  • Object of the present invention is therefore to provide a working element of the type mentioned, which does not have the mentioned disadvantages of the known prior art and allows easy adjustment of the ejection distance. additionally It is the object of the present invention to achieve a flexible design of the setting of the ejection distance and an improvement of the setting accuracy.

These elimination knives are embedded in working elements or are in the form of grates directly opposite rollers which transport the fibers and pass the elimination knife.
  • the inventive design of a provided with a Ausscheidemesser working element is used in the fine cleaning, preferably in machines for carding of fiber material.
  • the working element includes various devices such as the actual knife blade, carding or cover elements. Other devices such as measuring devices, sampling devices, guide elements and suction channels can also be accommodated in the working element.
  • the working element itself is shaped as a suction channel.
  • it is quite common to use for the extraction of the excreted on the knife blade parts a separate or patch suction even in such a case, the suction is attributable to the working element as a part of the same.
  • the working element is composed of a carrier and the devices held on the carrier.
  • the carrier is placed opposite a roller, for example a licker-in roller or a drum of a card.
  • the carrier and thus also the working element extends over the entire width of the corresponding roller or drum.
  • the carrier is supported at the outer ends of the roller on the side shields of the machine, in which normally also the roller respectively Drum is stored.

  • the two parts which are for example made as hollow profiles, held together with a clamp.
  • the clamp is mounted on the side of the working element facing away from the roller.
  • the two carrier parts are shaped so that they form a suction channel in the assembled state.
  • the roller opposite the carrier is a knife blade attached.
  • the knife blade is attached to the roller at an angle to the tangent so that the tip of the knife blade directed against the roller points counter to the direction of rotation of the roller and functions as a selector blade.
  • the attachment of the knife blade on the carrier can be made interchangeable as well as adjustable.
  • a carding element is mounted in front of the knife blade.

  • the carrier profile is designed such that the roller-facing surface of the carrier forms the cover. If the use of a carding element is not provided, the result of this embodiment of the support of the working element is the advantage of a favorable production, since it is possible to dispense with the formation of fastening possibilities for a separate carding element or covering element.
  • the size of the ejection distance is determined by the arrangement of the Ausscheidemessers, the installation of the working element and the properties of the fiber material to be processed. As the ejection distance increases, so does the amount of precipitate.
  • the present invention enables easy adjustment of the ejection distance. Such an adjustment of the ejection distance may be necessary in a batch change, a conversion of the material to be processed or a conditionally determined by fabrication specifications higher excretion. Due to the possibility of adjusting the ejection distance, a structurally identical working element can be used for different installation locations and only the setting of the ejection width can be changed.
