Definitions
- thermoplastic material in particular for welding plastic parts
- the invention relates to a method and a device for melting a thermoplastic material, in particular for welding plastic parts, in which (the) the plastic is heated by means of a radiation body by heat radiation and at the same time by applying a hot gas by convection.
- a method and a device of the generic type are known, in which (the) for melting the plastics they are heated by means of thermal radiation and at the same time acted upon with a hot gas.
- a hot gas either heated air is used, or it is a protective gas, for.
- nitrogen or other inert gas used which are supplied through openings in the radiation body to the plastic.
- the heating of the gas takes place by means of heating elements, such as heating wires or heating cartridges.
- the invention has for its object to provide a method and apparatus of the generic type, in which (the) the energy is used very efficiently.
- Figure 1 shows the side view of a welding machine with the invention
- FIG. 2 shows the section through a device according to the invention
- FIG. 3 is a perspective view of the embodiment according to FIG. 2,
- FIGS. 4 to 8 show the construction of the device according to FIG. 2,
- Figure 9 shows a perspective view of an alternative device which serves to melt a flat welding part.
- the apparatus 1 for melting plastics is part of a welding machine for welding plastic parts, which are provided in Figure 2 by the reference numerals 2 and 3.
- Welding machines are heated by means of the device 1, the surfaces of two plastic parts to be connected 2, 3 to the bonding temperature at which the plastics of both parts along the weld line are in a plastic state. The heated surfaces are then joined under pressure.
- the device shown in perspective in section and in FIGS. 3 to 8 serves in each case for heating a rectilinear, elongated and narrow joining surface 2. 1, 3. 1 on the plastic parts 2, 3.
- the device has at least one channel-shaped radiation body 4 which burns on its inside a heating gas is heated and the outer surface emits the combustion energy in the form of heat radiation.
- the radiation body 4 has outlet openings 5 for the combustion exhaust gases, which are respectively directed to the joining surfaces of the plastic parts 2, 3.
- the device For heating both plastic parts 2, 3, the device has two radiation bodies
- the two radiation body 4 are mirror images of each other and arranged and have a common supply channel 6 for the heating gas, preferably a gas / air mixture.
- both parts of the device each contain a supply channel 6 for the heating gas, the two channels when screwing the two parts close to each other, so that a shared feed channel 6 is formed in which distributes the supplied fuel gas evenly.
- Both channels 6 each have along their bottom a number of Gasaustrittsöffnu ⁇ gen 7, which are covered by a seal 8.
- On the seal 8 is a fleece 10, which in turn is covered by a cover plate 14.
- the seal 8, the fleece 10 and the cover plate 14 also have openings, so that the openings 7 are not covered.
- the openings 7, the seal 8, the fleece 10 and the cover plate 14 form a burner 9, the flame and exhaust gas space is the interior of the radiation body 4.
- the fleece 10 thereby causes the heating gas in the burner 9 burns very evenly.
- the burner 9 On the exhaust side, the burner 9 is closed by the channel-shaped radiation body 4, so that all the exhaust gases are passed through the radiation body 4 and then through the openings 5 to the outside.
- the radiation body 4 is heated via its inner side so that its outer surface radiates heat and releases it to the plastic part 2, 3.
- the heating gas is ignited by an igniter. It burns evenly in the burner 9 on the nonwoven fabric 10.
- the burner 9 is operated so that the radiation body 4 heats up strongly and emits radiant heat on its outer surface. This radiant heat is emitted via the correspondingly shaped surface 11 of the surface of the radiation body 4 to the joining surface 2.1, 3.1 of the plastic parts 2, 3.
- the exhaust gas formed in the burner 9 collects inside the channel-shaped radiation body 4, then exits through the openings 5 and impinges on the joining surfaces 2.1, 3.1.
- the radiating surface 11 of the radiation body 4 and the openings 5 are designed and arranged such that they follow the joining surface 2.1, 3.1 to be heated.
- a temperature sensor 12 is arranged in the region of the radiating surface 11 of the radiation body 4, which measures the temperature of the surface 11.
- the burner 9 is operated so that the desired temperature of the radiation surface 11 is established.
- a second temperature sensor 13 is arranged in the interior of the radiation body 4, from which the exhaust gas temperature is measured.
- the burner 9 can thus be controlled or controlled so that the desired exhaust gas temperature or temperature at the surface 11 sets.
- the joining surface 2.1, 3.1 of the plastic parts 2, 3 can be so targeted melt by the hot exhaust gas and by the radiant heat emitted by the radiation body 4.
- the gas / air mixture is adjusted for burning so that the oxygen content in the exhaust gas is minimal.
- the exhaust gas thus acts during heating of the plastic parts 2, 3 at the same time as inert gas.
- the formation of oxygen compounds on the surface of the plastic during heating is reduced or even avoided.
- the contour of the radiation body 4 is adapted to that of the plastic parts 2, 3 to be heated. If certain areas of a plastic nozzle 2, 3 exposed to heat radiation or convection are not to be heated, this can be achieved by means of blind-type covers. These covers are attached to the outside of the radiation body 4 at the corresponding locations and prevent the corresponding areas of the plastic parts 2, 3 from being heated up inappropriately.
- the radiating outer surface 11 of the radiation body 4 is circular on the outside and has a cross-shaped shape in the middle.
- a large number of outlet openings 5 for the exhaust gas from the combustion are arranged inside the radiating surface 11.
- the contour of the parts to be welded is shown, here by way of example a circle and a cross. It can also be any other contour corresponding to the weld seam are displayed.
- the openings 5 are arranged according to the weld seam.
