Definitions
- the invention relates to film blowing heads, for the production of single or multilayer tubular films according to the preamble of claim 1.
- Film blowing heads for the production of single-layer tubular films consist of a central mandrel and a jacket surrounding it concentrically. Between shell and mandrel is an annular gap through which the melt is transported to the annular gap nozzle.
- the mandrel is provided on its outer circumferential surface with one or more helical grooves, the spiral distributor. The depth of the grooves decreases from the beginning of the annular gap to the annular gap nozzle.
- the plastic melt is conveyed via one or more Schmelzezu GmbHen to the initial regions of the grooves of the spiral distributor, so that a portion of the melt is transported in the helices in the die in the direction of the annular die. Due to the decreasing groove depth more and more melt is conveyed via the webs separating the grooves in the axial direction, (see DE 199 24 540 C1 or DE 23 06 834).
- Film blowing heads for multilayer tubular films differ from those for single-layer tubular films in that the central mandrel is coaxially surrounded by a plurality of ring elements.
- the inserts have on their outer lateral surfaces spiral distributor. Between the individual inserts annular gaps are formed. The various annular gaps are brought together in front of the annular gap nozzle.
- the distribution helices of the individual ring elements are also connected to one or more melt supply devices, so that they are supplied with melt (see DE 23 20 687 or DE 195 21 026).
- a film blowing head for multilayer tubular films is described in EP 1 055 504 B1.
- the inserts are cone-shaped and are arranged on top of each other.
- two counter-rotating spiral channels are incorporated with decreasing towards the mouth depth.
- the spiral distributors are incorporated both in the inside boundary wall and in the outside boundary wall of the at least one melt channel. As a result, foil contamination is prevented by specks.
- the helices of the inner and outer boundary walls of the melt channels can be arranged congruent or offset from each other.
- the spiral distributor has the function of distributing the melt uniformly in the annular gap.
- the melt is divided by primary distributor into several individual streams, which open in the channels of the spiral distributor.
- the melt stream flowing in the coils is split continuously.
- a tangential part which follows the course of the helix and in an axial part, which flows over the web existing between two helices in the gap between two ring elements in the direction of the annular gap nozzle. Therefore, at each point on the circumference of the outlet ring gap melt flows, which comes from a superposition of the axial and tangential melt streams of all distribution channels.
- an initial gap In order for an axial spiral flow to be established, an initial gap must be set at the level of the starting region of the spiral distributor. A part of the melt flows abruptly from the beginning of the helical channel in the annular gap. The plastic flows along the production-related start edge and is therefore particularly oriented and sheared. This fast, axially flowing melt stream displaces melt areas of the upstream channel, creating a sharp boundary between the melt streams, so-called spiral strips or portlines. This has a negative effect on the quality of the film tube. Plastics have a memory effect, therefore, a place with special To recognize history (in terms of stress, temperature, etc.) on the film as a dull or wavy area.
- the object of the invention is. to provide a Folienblaskopf of the aforementioned type, which allows the production of Folienblasschläuchen without the emergence of sharp boundary areas between the axial melt streams, which can be seen on the film as turbid or wavy areas.
- the individual layers are formed according to the same procedure.
- the film blowing head has three concentrically arranged annular gaps. Melt flows from the spiral distributor, which is located on the inner boundary wall of the respective melt channel, in the annular gap. Thereafter, the melts are brought together in the outlet ring channel. All damaged melt areas of the inner and middle layer are completely embedded in the melt after the three individual layers have merged together. In this state, various balancing and relaxation processes of the plastic molecules take place. Only the damaged melt of the outer film layer always remains in contact with the metal surface of the Blaskopfgephinuses. There can be no homogenization and the flow history is visible after the nozzle exit on the film.
- the critical combination in a die is therefore the gap between the web of the outer ring member and the cylindrical counter surface of the housing.
- this spiral distributor is virtually mirrored.
- the spiral channels, the spiral distributor are no longer incorporated into the outer circumferential surface of the outer ring member, but in the inner circumferential surface of the housing.
- the helical discharge now takes place in the direction of the inside, which then comes into contact with the melt of the other layers. This ensures that the damaged melt areas of both the inner, the middle and the outer layer after the confluence of the individual layers are completely embedded in the melt.
- the extrusion of a film without turbid lines (portlines) and wavy areas is possible.
- Figure 1 Folienblaskopf in a partial sectional view.
- a film blowing head according to the invention is shown in a preferred embodiment in partial section. It is a blow head for producing a three-layer tubular film.
- the film blowing head (1) comprises an inner cylindrical mandrel (3), which is concentrically surrounded by a first ring element (5), which in turn is surrounded by a second ring element (4).
- This second ring element (4) is surrounded concentrically by a third ring element, in this case the housing (2).
- an annular gap (9, 10, 11) the melt channel is formed leading to the annular gap nozzle (12) getting wider and wider.
- the annular gaps (9, 10, 11) are combined into a gap in front of the annular gap nozzle (12).
- the mandrel (3) has on its outer circumferential surface a spiral distributor (8).
- the depth of the coils decreases in the direction of the annular gap nozzle (12).
- the spiral distributor consists of one or more grooves incorporated spirally into the corresponding component.
- the inner ring element (5) also has a spiral distributor (7) on its outer lateral surface.
- the second ring element (4) has no spiral distributor.
- a further spiral distributor (6) is incorporated in the inner casing of the housing (2).
- the melt is transported via the melt supply (13) into the film blowing head (1), where it is conveyed via various distributors, not shown here, to the beginning of the spiral distributors (6, 7, 8). From the beginning of the coil, the melt is once distributed in the tangential direction in the helices over the circumference of the annular gap (9, 10, 11), on the other in the axial direction in the annular gap (9, 10, 11) between coil distributor and flat cylindrical boundary wall of the adjacent ring element. At the upper end of the annular gap, the tangential component decreases as a result of the decreasing depth of the grooves of the spiral distributor and due to the annular gap becoming wider relative to the annular gap nozzle, and the axial component continues to increase. Before the annular gap nozzle, the individual melt streams are brought together and fed as a film from the film blowing head.
- an inventive film blowing head is to be provided for multilayer tubular films of more than 3 layers, further annular elements are arranged between the outer and inner annular elements, the spiral manifold of the inner melt channel being arranged with respect to the central axis of the film blowing head on its inner boundary wall and the spiral distributor of the outermost one Meltkanal with respect to the central axis of the film blowing on its outer Bounding wall is incorporated.
- the film blowing head is to be provided for the production of single-layer tubular films, the film blowing head consists of mandrel with spiral distributor on the outer circumference, ring element without spiral distributor and housing with spiral distributor on the inner jacket.
- Film blowing heads which are intended for the production of film tubes, in which the formation of helical strips, cloudy stripes or wavy areas, are to be avoided, are constructed so that the outer spiral distributors are directed to the inner and outer surfaces of the film tube to be produced.
- the film blowing head can be equipped with a mandrel, a ring element and housing, but also with a plurality of ring elements, depending on the desired number of layers of the film tube.
- the spiral distributors of the middle melt channels can optionally be arranged on the inner or outer boundary wall of the associated melt channel.
