Definitions

  • the invention relates to a device for opening flake fiber material made of natural or synthetic fibers, a housing with a built-in opener disc and which is installed via a supply connection piece and a discharge connection piece in a pneumatic conveyor line for processing the fiber material.
  • Such devices are known in a wide variety of embodiments.
  • a device for opening and cleaning fiber material with two opposing rollers is known, which are mounted in parallel above a lattice bar, grating or the like and below a closed cover hood and provided with pins or the like , wherein the inlet and outlet openings are arranged so that the fiber material is fed in and out in a direction lying parallel to the rollers by means of an air stream.
  • pin rollers require a large footprint, have a low throughput, a poor degree of opening and are subject to high wear. There is also a risk of the rolls forming on the rolls and subsequently blocking them.
  • GB-A-996 604 shows a fiber opening and cleaning machine with a driven opener disc built into a housing which is opposed by a stationary counter-opener disc to form a space.
  • a fan wheel on the drive shaft of the opening disc, which is opposite the central opening in the counter opening disc.
  • the opening of the counter-opening disc is connected to a material feed line via a cone-shaped pipe section which opens into the housing from above.
  • the opener disk and the counter-opener disk are surrounded on their periphery by fixed grille bars, through which on the one hand dust in the horizontal direction into an annular chamber lying inside the housing and on the other hand fiber material opened in the vertical direction into a hood attached to the top of the housing and connected to a suction line reached.
  • GB-A-478 760 discloses a Crighton opener with an inverted U-shaped housing which is set up on a floor of the floor and which in its interior accommodates a shaft which is supported on the floor in the lower region and on the side of which there is a feed line - Connection piece is connected.
  • the shaft carries on its upper side a basket made of individual lattice bars, which widens from it in the shape of a truncated cone.
  • a driven opening device which is connected to a discharge connection piece and which is designed as a cross wheel and acts as a racket to drive foreign matter downward in the direction of the floor.
  • Suction nozzles are assigned to the basket laterally within a chamber between the basket and the housing, through which lighter foreign matter is continuously extracted.
  • the invention has for its object to provide a device of the type mentioned, which ensures high efficiency with a structurally simple and compact structure and avoids the occurrence of fiber traps in the opener area.
  • the inlet connecting piece opening into the housing at the bottom extends into a hollow cylinder which is open at the top and extends into the cylindrical housing connected to the outlet connecting piece, forming an annular chamber, with a certain parallel distance from the free end face of the hollow cylinder a driven opener covering this, which is equipped with pointed pins in the direction of the hollow cylinder, is arranged.
  • the main advantages achieved with the device according to the invention are a small footprint, a good degree of opening, few construction and wear parts and high performance.
  • the fiber air flow entering the supply connection piece emerges after passing through the hollow cylinder from its open end face and is then gripped by the opening disk running at a relatively high speed, the flake-shaped fiber material being opened by the pins of the opening disk and due to the centrifugal force together with the air is passed through the peripheral outlet slot between the opening disk and the hollow cylinder into the annular chamber, from which the fiber air flow is then sucked out via the discharge nozzle. Since the fiber material in the area of the opening disk is subject to a high centrifugal force, no winding formation occurs on the opening disk.
  • a fixed, circular segment-shaped counter opening disc is inserted into the end face of the hollow cylinder and is equipped with pointed pins in the direction of the opening disc.
  • the opener disc becomes the fiber airflow fed compressed only in a certain area, and the counter-opening disc in cooperation with the opening disc ensures safe opening of the fiber material.
  • the chord of the circular segment-shaped counter opening disk runs at a distance from the diameter of the counter opening disk, which is defined by a circumferential angle of approximately 200 °, according to an advantageous development of the invention .
  • a circumferential angle of approximately 200 ° is defined by a circumferential angle of approximately 200 °
  • the counter-opening disk is provided with pins only in an angular range of approximately 120 °.
  • the pins of the counter-opening disk are expediently arranged in a row from a free central area in a radially outward direction.
  • the pins of the counter-opening disk are preferably mounted inclined in the direction of rotation of the opening disk.
  • the pins of the opening disk are expediently arranged running from a free central area in crescent-shaped rows to the periphery, the pins of the opening disk preferably being arranged inclined outwards.
  • the opening disk is surrounded by an annular flange attached to the cover of the housing, on the outside of which a shield attached to the hollow cylinder, which extends over the circumference of the pin area of the counter-opening disk, slides.
  • a shield attached to the hollow cylinder which extends over the circumference of the pin area of the counter-opening disk, slides.
  • the opening disk is connected in its central region via a retaining flange to a drive shaft which extends through a bearing block placed on the cover of the housing and carries a drive wheel coupled to a drive motor via a gear.
  • a drive shaft which extends through a bearing block placed on the cover of the housing and carries a drive wheel coupled to a drive motor via a gear.
  • ventilation holes are let into the cover of the housing, which open out into the space delimited by the opening disk and the annular flange.
  • the lower region of the hollow cylinder is designed in the shape of a truncated cone. This slows down the ascending fiber air flow, causing heavy fiber flakes to swirl within the hollow cylinder, which loosens them up.
  • the height adjustment of the supply pipe connecting piece carrying the hollow cylinder is carried out via a rack and pinion drive. This results in a simple adjustment of the distance between the opening disk and the counter-opening disk, as a result of which the opening effect can be adapted to the respective fiber air flow.
  • the lower region of the housing is designed to taper conically towards the bottom of the housing, with the discharge connecting piece extending tangentially from this region.
  • a fresh air supply nozzle provided with an adjusting flap preferably opens into the conical region of the housing opposite the discharge connection piece. This makes it possible to prevent fiber deposits in the bottom area of the housing by supplying fresh air.
  • the device 1 comprises a cylindrical housing 2, the lower region of which is designed to taper towards the bottom 3 of the housing 2.
  • the supply connection piece 5 In its variable position within the ring flange 4, the supply connection piece 5 is fixed by a rack and pinion drive 6 coupled to it.
  • the supply connection piece 5 flows under suction pressure, loaded with fiber flakes transport air flow from a fiber flake machine in the direction of arrow D into the device 1.
  • the supply connection piece 5 is connected to a hollow cylinder 7, the lower one Area of the hollow cylinder 7 from the supply connection piece 5 is designed to expand in the shape of a truncated cone.
  • the housing 2 has at its upper end on the outside a circumferential ring flange 12 which is connected to a cover washer 14 by means of screws 13 distributed uniformly over the circumference.
  • the opening 15 of the cover ring disk 14 is closed by a cover 16 resting thereon. Screw connections 17 distributed uniformly over the circumference secure the cover 16 in its position.
