Definitions

  • the invention relates to a device for increasing the cooling capacity of an extrusion line and for energy-efficient extrusion of a plastic profile, in particular a plastic tube, comprising at least one extruder, a profile-forming tool, consisting of at least one inner rim and an outer rim, wherein the inner rim and the outer ring are connected to webs, a calibration and further downstream equipment.
  • the invention also relates to a related method.
  • the solution of the object to the device is characterized in connection with the preamble of claim 1, that one or more of the webs connecting the inner ring and the outer ring has a channel, wherein the channel has a fluidic connection between the inlet region for a cooling medium on the one hand and forms the Profilholraum on the other hand.
  • a web with one channel is sufficient, but for better melt distribution it should be two or three webs, whereby not necessarily in each web a channel for blowing the cooling medium is required. With increasing diameter of the profile cross-section, the number of webs should also be increased. Fortification according to several webs are provided with a channel, wherein the webs are arranged in a plane. In a section perpendicular to the extrusion axis through the webs therefore all webs would cut because they are on a plane. It can thus be NEN relatively simple annular channel all channels in the webs are connected to a blowing device.
  • the webs are distributed symmetrically over the circumference.
  • the webs can also be arranged vertically, rotated and / or offset from the extrusion direction.
  • the device can also be used in the reverse flow direction of the gaseous medium.
  • a suction device is to be used and the blowing effect described above is a suction effect or a blowing of the air used, for example, is to be understood as suction.
  • the object with respect to the method is in conjunction with the preamble of claim 8 gel ö stung that for internal cooling of the profile, a gaseous medium in the extrusion direction is blown through the extruded plastic profile, wherein the gaseous medium by at least one channel in a web within of the tool is blown, wherein the gaseous medium is additionally blown through the profile before it is released into the ambient air.
  • air is blown through the tool via the channels arranged in the webs through the interior of the profile to the end of the extrusion line and released to the environment.
  • the air can also be blown through a plurality of the channels of the device described above and thus the blowing power and the flow velocity of the air are influenced by the interior of the profile.
  • the device can also be used for sucking the gaseous medium, this of course also applies analogously to the claimed method.
  • the gaseous medium is then sucked through the profile and through at least one channel in a web inside the tool and then released to the environment.
  • Fig. 1 shows a typical extrusion line
  • Fig. 2 shows a partial area with extruder and tool
  • FIG. 3 is a section through the tool FIG. 1 shows a typical extrusion line, as used today for profile extrusion, for example for the production of window profiles or pipes. It shows an extruder 1 in which plastic is melted and continuously conveyed into the extrusion tool 2 for shaping. This is followed by a calibration and / or cooling device 3 connects. Depending on the profile, additional cooling stations can be used. After the cooling stations, a trigger device 4 connects. In order to cut off the endless profiles 6 to the desired length, a separating device 5 is then arranged. All parts extend along the extrusion cages 8. The extrusion direction is indicated by the arrow 7. A fan 14 is arranged directly on the tool 2 to suck the gaseous medium 11, here air, and to blow through the system.
  • a fan 14 is arranged directly on the tool 2 to suck the gaseous medium 11, here air, and to blow through the system.
  • FIG. 2 shows a partial area with the extruder 1 and the tool 2, which gives the profile 6, in this case a plastic tube, the shape before it is calibrated by means of some of the downstream units shown in FIG. 1 and cured to dimensional stability.
  • a gaseous medium 11 is blown.
  • the gaseous medium 11, preferably air, is blown from the inlet region 12 on the tool 2 through the channels 10 located in the webs 9 into the profile 6, conveyed through its interior and discharged again at the outlet region 13 at the end of the profile 6 to the environment.
  • the extrusion direction is again marked by arrow 7.
  • Figure 3 shows a section through the tool 2, wherein the section is perpendicular to the extrusion axis through the webs 9 and includes only the essential parts for the description of the invention. Since the section runs perpendicular to the extrusion axis 8, the extrusion axis 8 can only be seen as a point.
  • the tool 2 comprises an inner rim 2a and an outer rim 2b. Both parts are via webs 9, here by way of example eight webs are shown connected to each other.
  • a support ring 2c is arranged between the inner ring 2a and the outer ring 2b through which the melt flowing through is further divided. The support ring 2c is not mandatory.
  • All eight webs are arranged in a plane and each have a channel 10.
  • the channel 10 has on the side to the inner ring 2a a fluidic connection to the profile cavity and thus also a connection to the environment.
  • the fluidic connection is given to the fan 14, not shown.
