Definitions

  • the invention relates to a supply device for one or more components of a free-flowing and a difficult pourable feed material to a processing machine with different components.
  • the invention is therefore based on the object to avoid the disadvantages mentioned and to provide a supply device for one or more components of a free-flowing feed, in which a high degree of homogeneity in terms of the substances to be processed is ensured.
  • the essential advantage of the invention lies in the fact that the component, which consists of vegetable fiber materials, comes into contact with liquid in a mixing device, that is, the liquid is metered in and at the same time mixed with the material.
  • the liquid is finely atomized and exposed to both components, i. both the vegetable fiber material component and the further component, detected and supplied gravimetrically.
  • the second component consists of hemp in ground form.
  • Hemp flour is ideal as an additive to products to reduce weight and use as sound insulation.
  • Hemp flour is ground press cake, which is obtained during the extraction of oil from hemp seed.
  • the first component is a plastic granules, in particular a thermoplastic plastic granules. Especially in combination with hemp flour a good mixing before processing is necessary.
  • the first component is removed via a suction conveyor from a reservoir and passed through an intermediate container to a gravimetric device.
  • the material to be processed has a water content of 0.3 to 8.0 percent by weight, depending on the recipe.
  • the invention also relates to a process for producing a thermoplastic molded body, wherein particles of a vegetable material with at least one thermoplastic material are mixed.
  • the supply device has a reservoir 10 in which thermoplastic granules are located. At this reservoir, a removal device 11 is arranged. This removal device 11 is connected to a delivery line 12, the delivery line leads to a conveyor 13. The conveyor 13 is equipped with a suction pump 14.
  • a further reservoir 15 is provided.
  • the reservoir 15 is equipped with a mixer 17.
  • a metering screw 18 is arranged below the reservoir.
  • the hemp flour is fed to a hopper balance 19.
  • Above the hopper scale is an intermediate container 20, which is connected between the conveyor 13 and the filling opening of the hopper scale 19.
  • a mixing device 21 is provided below the hopper scale. This mixing device is connected to a water connection 22. The water is finely atomized fed to the mixing device 21 via line 23.
  • the mixed material passes via the line 24 to a reservoir 25 and from there via a screw conveyor 26th to a machine hopper 27, which is arranged on a plastic injection molding machine or Kunststoffxtrudiermaschine 28.
  • the entire device is operated via a control device 29 and defines the process.
  • the process control is continuous or discontinuous.
  • the removed from the reservoir 10 plastic granules is usually fed discontinuously to the conveyor 13, passes from there via the intermediate container to the hopper scale 19, which detects a certain amount, which is to be mixed with the hemp flour.
  • the weighed material passes into the mixing device 21 and is mixed there by circulating agitators, at the same time finely atomized water is supplied until the appropriate moisture content is set.
  • the thus prepared material passes through a discharge valve 30 to the reservoir 25th
  • thermoplastic molded body formed by the injection molding machine may be used as a member having excellent acoustic properties, i. find application with a high insulating effect in a vehicle.
  • the component can also be used as a technical element for the production of profiles for the construction industry.
  • FIG. 2 shows the in FIG. 1 described reservoir 25, which is provided with a stirrer construction 31.
  • This improves the transportability of the supplied mixture and consists of a drive shaft 32 which is driven by a motor, not shown here.
  • On the drive shaft 32 individual stirring rods 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44 and 45 are arranged in a different configuration.
  • These stirrers can be attached to other positions as required and can thus be optimally adjusted to the consistency of the mixture supplied.
  • a paddle 64 At the lower end of the drive shaft 32 is a paddle 64, which ensures good transport of the container contents in this area of the reservoir.
  • FIG. 3 shows a variant for filling the reservoir 15 in FIG. 1 , It is a suction container 46, which is equipped with a suction nozzle 47.
  • the proboscis is plugged into a side wall of the suction container 46 and operates with negative pressure, ie the material contained in the suction container 46 - in this case hemp flour - is fed to the storage container 15 with negative pressure via the suction grommet 47.
  • a loosening device 48 consisting of a shaft 49 and bars 50, 51, 52, 53, 54, 55, 56 arranged thereon.
  • the shaft is driven by an electric motor 57.
  • the rods loosen the hemp flour in the container and ensure that no bridges or cavities form in the lower region, ie in the region of the suction pipe 47.
  • the trunk is arranged laterally offset to the loosening device 48. At the same time inclined at an angle of about 10 ° to 20 ° so that the suction point 58 is close to the last stirring rod 56.
  • the suction nozzle 47 is equipped with a tube 59 which is led to the reservoir.
  • the lid 60 is removed. Equipped with rollers 61, 62 and a transport handle 63, the suction container is displaceable and can thus be adapted to different local conditions.
