Definitions

  • the invention relates to a device for admixing a first granulate located in a first container with a second granulate located in a second container.
  • a device of this type is known in practice.
  • granules are understood to be a granular material whose grain size can vary within wide ranges, i.e. Powdery components can be processed with the mixing device according to the invention as well as large-grain components.
  • Coloring devices for mixing granular or powdery dyes, additives and the like are known. Such devices can be used as building blocks in an injection molding machine system.
  • a disk provided with outer chambers rotates as a metering cell in a horizontal plane below the material to be metered and at a certain point drops the product taken up by the chambers into a mixer.
  • the individual components are fed to the mixer in the ratio preselected to a control unit and mixed so intensively by a mixing tool that it homogeneously leaves the mixer outlet.
  • the main disadvantage of these known coloring or mixing devices is that a first good is metered into a second good from two separate containers in a third additional container and has to be mixed there for a certain time before the final product is mixed in the desired mixing ratio can leave third mixing container.
  • a first good is metered into a second good from two separate containers in a third additional container and has to be mixed there for a certain time before the final product is mixed in the desired mixing ratio can leave third mixing container.
  • more space and working time are required in the known mixing devices; because in addition to the basic granules or basic materials, the mixed materials must also be collected in an additional container and mixed there.
  • the respective stirring tool is equipped with additional drives, and the overall control for setting the correct mixing ratio is complicated. Overall, the known device is to be regarded as very complex and it is not possible to continuously adjust the mixing ratio.
  • a conveyor line is connected to a conveyor and a supply line for the supply of the first granules to be mixed is connected to the conveyor line
  • the second container is located at an upstream position of the conveyor line that under the outlet opening of the the granulate-containing first container is arranged a gap formed by two rollers and adjustable in its width
  • a connecting channel is provided between the gap and the feed line and that at least one of the two rollers is driven by a motor.
  • a similar metering device is known from document DE-U-6 901 530, in which a conveyor roller is provided over the outlet opening of a funnel-shaped silo container, under whose conditions two rollers with parallel axes are also arranged next to one another under certain conditions. By regulating the speed of the drive motor of these rollers, the passage quantity of the material to be discharged from the silo container can also be regulated.
  • the known device wants to avoid bridges and deposits on walls, so that a continuous outlet is achieved even without vibrators and blown air. For the production of artificial stone slabs, their quality is to be improved by the automatic introduction of the facing.
  • the facing material falls into a shape placed under the silo container and can be evenly distributed there.
  • the supply line for supplying the first granules to be mixed is connected to a delivery line through which the second granules are conveyed.
  • the width of the gap between the two rollers is changed.
  • the mixing device according to the invention is used as a coloring device, then the coloring can obviously be adjusted continuously.
  • the mixing of the components or of the first granulate with the second takes place in an advantageous manner through the continuous feed of the first granulate to be mixed into the second granulate which is in motion.
  • a special mixing device with the corresponding control, the agitator and the like are therefore eliminated.
  • the invention is advantageously further designed in that the gap between the two rollers is adjustable to a width of at least 1 mm.
  • the more or less fine grains can then only be used individually in a single layer, i.e. H. not several grains next to each other can be set in motion by the peripheral speed of the rollers.
  • the gap with its adjustable width automatically changes the number of granules per unit of time.
  • At least one of the two rollers has a covering made of an elastic material on its peripheral surface and if preferably both rollers are driven synchronously with one another. In this way, the speed of the granules passing through can be precisely controlled, and the granules are treated carefully due to the elastic coating of the rollers, avoiding surface abrasion or even grinding.
  • the drive motor of the rollers is a DC motor
  • the peripheral speed of the rollers is controlled in a particularly fine and reliably controllable manner, so that the mixing ratio can be continuously adjusted in a very fine manner.
  • the invention remedies this by providing a vibrating device above the outlet opening and / or in the lower region of the first container.
  • the same drive as for the rollers generates a shaking movement which is transmitted, for example, to a shaker in the form of a hook, wire or lever. In this way, any bridging during the course of operation is prevented, so that the material flow of the respective granulate is reliably ensured.
  • the feed line has a preferably adjustable suction throttle.
  • the feed line opens into the main conveyor line, in which, for example, the main granulate or second granulate is conveyed from a main container to the processing station.
  • a vacuum is created by the movement of the gas / granulate mixture, so that this and the vacuum in the delivery line also create such a pressure in the delivery line. This automatically ensures the conveyance of the particles or granules removed from the rollers with a certain amount per unit of time.
  • a suction throttle is arranged on the feed line in the manner described above, the feed speed of the granules removed from the rollers can be changed from the feed line into the main feed line. Clogging of the feed line is thus advantageously eliminated.
  • Another embodiment of the invention is advantageously designed in that the feed line has a viewing opening in the mouth region of the connecting channel. The flow of the first granules to be mixed can thus be observed.
  • the inflow of the first granules which in the case of a coloring device can represent, for example, the coloring granulate, can thus be regulated by the speed of the rollers and the roller gap formed by these.
  • the device according to the invention advantageously ensures that the granules from the container above the nip, e.g. the coloring granulate is conveyed in just a single row of granules. It is hereby not possible for about two rows of granules to lie one above the other in the nip and in this way to be able to pass one another through the nip between the two rollers. This in turn enables exact metering of the granules to be mixed in by adjusting the speed of the DC motor.
  • FIGS. 1 to 4 is a coloring device in which an additional or colored granulate with a grain size of approximately 2 mm is contained in a first container 9, from which it is transferred via rollers 1 and 2 to the intermediate roller gap 8 is conveyed to the conveying line 5, in which the main granulate to be colored is conveyed in the direction of arrow 20 by suction.
  • the container for the main granulate to be colored for example a transparent granulate for creating Plastic caps, is not shown in Figure 1, but connects to the delivery line designed as a granulate suction pipe 5.
  • the processing station with the extruder is also not shown.
  • the so-called first granulate can fall out of the first container 9 while avoiding the formation of bridges by means of the vibrating device 17 into the opening 6 as the outlet of the container 9 and from there into the funnel 7, which in the illustration of FIGS. 1, 2 and 4 is downward tapered, partially with flattening and eccentrically to the opening 6.
  • the granules fall into the nip 8 of the two rolls 1 and 2 covered with a covering 16 made of elastic material in the embodiment shown here (for example silicone rubber).
  • a covering 16 made of elastic material in the embodiment shown here (for example silicone rubber).
  • a connecting channel 14 in the form of a metering shaft. This opens into the feed line 10, which in turn ends in the suction pipe 5.
  • a suction throttle 18 On the end of the feed line 10 opposite the mouth of the feed line 10 in the suction pipe 5 there is a suction throttle 18 in the form of a suction air screen.
  • an opening bottom right in FIG. 1 above the drive motor 15 is more or less closed adjustable by a slide, so that the suction throttle results.
  • rollers 1 and 2 are driven via the drive motor 15 and the chain or toothed belt 3, as can be seen in a side view in FIG. 1 and in a top view in FIGS. 2 and 3.
  • FIG. 1 shows the fastening of the entire device to the suction pipe 5 by means of the clamping association, generally designated 28, the holder 26 for the motor 15 and the viewing opening 19 in the form of a continuous bore which crosses the feed line 10.
  • FIG 3 clearly shows the drive conditions.
  • the drive gear 4 which drives the connecting gear 12 and the rubberized roller 1 via the keyed shaft, is driven by the DC drive motor 15 via the toothed belt 3.
  • the latter is attached via the driver pin that runs transversely at the bottom.
  • the nip 8 which has a width of 1 mm in the embodiment described here. In other words, the smallest distance between the two rollers 1 and 2: 1 mm.
  • a further connecting gearwheel 11 is driven by the gearwheel 12, which drives the second roller 2 and a gearwheel 29, which is also shown in FIG. 4 and shows the drive for the vibrator 17, via the shaft with key-and-spline connection shown.
  • the bearings and spacer sleeves of the shafts for the connecting gears 11 and 12 as well as the rollers 1 and 2 are not described in detail here.
  • FIG. 4 illustrates the vibrator 17, which is designed as an L-shaped pin and is firmly soldered in the axis 24. This is seated in the bushing 23 in the housing or base body 22.
  • the connecting connector 25 is also shown in FIG. It is understood that the vibrator 17 is arranged in the funnel-shaped outlet 7 in the area above the metering opening 13. It receives its oscillating movements in that, according to FIG. 4, a clamping piece 27 slides over the teeth of the toothed wheel 29 by the tension of a spring 33. 30, 31 are the screws for fastening the corresponding wheels, here the drive wheel 4 or the connecting gear 11 on the drive axle.
  • the retaining bolt 32 for the tension spring 33 is also shown for a better understanding of the structure of the entire vibrating device.
  • the grains of the first granules in the first container 9 fall through the outlet opening 13 into the nip 8.
  • a number of granules are conveyed more or less quickly through the connecting channel 14 into the feed line 10 and from there, depending on the setting of the suction throttle, is conveyed into the main suction line 5, in which, in the direction of arrow 20, a transparent granulate for the production of container caps is sucked from the main container (not shown) to a processing station.
