Definitions
- the invention relates to a meltblown system for Manufacture of meltblown products, with one filament dispensing nozzle head, being below the nozzle head a continuously movable deposit screen belt is arranged, on which the filaments for the meltblown product can be deposited and wherein a suction device for Sucking in air through the deposit screen belt is provided.
- a meltblown system or in the meltblown process the polymer melt emerging from the nozzle head of a stream of blown air. This turns the Melt polymer fibers formed, which are then used for Meltblown product are placed on the lay-out belt.
- meltblown products are often made receive the undesirable irregularities or Have inhomogeneities.
- meltblown systems take place in the extraction zone or in the area of the deposit screen belt is often a more or less strong one Fiber flight instead of an uncontrolled filing of the fibers conditional and therefore irregularities in the meltblown product causes.
- These irregularities affect in particular the product thickness, air permeability and ratio Cross strength / longitudinal strength of the fiber mat produced as well as irregularities in the surface of the Meltblown product. The result is product quality of meltblown products left a lot to be desired.
- the invention is the technical problem based on a meltblown system of the type mentioned to indicate with which meltblown products are manufactured can stand out through homogeneity and uniformity distinguish themselves in terms of their properties and in particular also have an optimal surface quality. It should especially meltblown products that can be made a uniform product thickness and a constant Have a ratio of transverse strength / longitudinal strength. Also the air permeability is said to be at different points of the Meltblown product should be as constant as possible.
- the Invention a meltblown system of the type mentioned in the introduction, which is characterized in that the deposit screen belt in its longitudinal direction several separated from each other Suction areas that one of these suction areas is a main extraction area assigned to the deposit zone and that the suction speeds in the suction areas are each independently adjustable.
- the deposit screen belt In the longitudinal direction of the deposit screen belt means in the conveying direction or transport direction of the lay-off belt.
- the several separate suction areas are in Direction of conveyance or transport direction of the lay-off belt arranged one behind the other.
- drop zone is the area of the lay-off belt where the largest Part of the filaments is deposited or in which all or almost all filaments are deposited.
- Suction speed In every extraction area the suction speed is separate and independent from the other extraction areas. Suction speed means the speed of through the sieve belt is sucked in or sucked in air m / s.
- the suction device is or are expedient the suction fan of the suction device below the deposit screen belt arranged.
- the filaments dispensing nozzle head is designed as a meltblown blow head. It is also within the scope of the invention that the Nozzle head of the meltblown plant a variety of in one Row arranged nozzle bores or nozzle openings for has the polymer melt outlet. After that is only a single row of nozzle openings is provided. henceforth preferably has the meltblown system according to the invention a longitudinal nozzle for the exit of tempered blowing air with which blowing air the polymer melt or the emerging filaments are acted upon.
- At least three are preferably separate from one another Extraction areas in the longitudinal direction or in the conveying direction of the Deposit screen belt arranged one behind the other.
- the main suction area is the suction area.
- four are of particular importance separate suction areas are provided and there is a first suction area and a second suction area in relation on the conveying direction of the depositing belt before Main suction area arranged and there is still a third suction area in the conveying direction of the deposit screen belt arranged behind the main suction area.
- This Embodiment with four separate suction areas has particularly been within the scope of the invention proven.
- the suction speed in the main suction area is higher than in other suction areas.
- the Extraction speed in the main extraction area higher than that Suction speeds in the first, in the second and in third suction area.
- the suction speed is expedient in the main extraction area at least twice high as the suction speed in each of the others Suction zones.
- the suction speed is preferred in the main suction area at least twice as high as that Suction speed in the first suction area or in second suction area.
- the Suction speed in the main suction area at least twice the suction speed in the third Suction.
- the invention is everyone Extraction area assigned its own suction fan.
- This embodiment has the suction device Meltblown system so several suction fans.
- the suction speed can be on any suction fan for everyone Extraction range can be set separately. So it takes place an independent regulation of the exhaust air flow in each Extraction area instead.
- the extracted volume flows can can be set completely independently.
- the Adjustment can be made with the proviso that the suction power in the main suction area is twice as high is as large as in any of the other extraction areas.
- the individual suction areas are expediently through Boundary walls made of sheet metal separated. These are preferably vertically oriented Metal sheets. Vertical also essentially means here vertical.
- the invention is based on the finding that with the meltblown system according to the invention the storage of a Meltblown product or a nonwoven web optimal and can be controlled reliably.
- Design can an undesirable fiber flight in Area of the deposit screen belt excluded or effective be reduced.
- By realizing the different Suction areas can be a very even thread deposit can be achieved and inhomogeneities in the filed Meltblown product can surprisingly be largely minimized become. Disturbing thick spots or thin spots in the manufactured meltblown product are not observed. Also disturbing inhomogeneities with regard to air permeability of the fleece or in relation to the ratio Cross strength / longitudinal strength can be excluded become.
- the main suction area can be opposite in the meltblown systems known from practice
- Existing suction area in relation to the longitudinal direction or the transport direction of the deposit screen belt is shorter become. This results in an advantageous one Energy saving because of the total extracted air volume flow can be reduced.
- Subdivision into different extraction areas would have to the only extraction area in the drop zone that has a high Suction speed required in the direction of transport Deposit screen belt to be made wider. Both known meltblown systems is therefore an unnecessarily high Extracted volume flow, which in turn requires a lot of energy means.
- the figures show a meltblown system according to the invention for the production of meltblown products, namely nonwoven webs.
- the meltblown system has a nozzle head 1, 2 filaments 3 are extruded from the nozzle openings.
- the Nozzle head 1 a row with a plurality of nozzle openings 2 on.
- the filaments 3 are tempered Blown air 4 applied, the direction of flow in the Figures is represented by corresponding arrows.
- Below of the nozzle head 1 is a continuously movable Ablegesiebband 5 arranged on which the filaments 3 to Meltblown nonwoven web can be discarded. Through the sieve belt 5 air is sucked in, so that the filaments 3 as it were the sieve belt can be sucked.
- the deposit screen belt 5 has four from each other separate suction areas 6, 7, 8, 9.
- One of these Suction areas 6, 7, 8, 9 is that assigned to the deposit zone Main suction area 8.
- Storage zone means the area the lay-off belt 5 on which at least most of the Filaments 3 is deposited.
- Suction speeds in the suction areas 6, 7, 8, 9 each independently adjustable.
- the suction speed in the main suction area 8 is higher than in the other suction areas 6, 7, 9
- Suction speed in the second suction area 7 expediently higher than the suction speed in the first Suction area 6.
- Each suction area 6, 7, 8, 9 is after preferred embodiment of the invention own Assigned suction fan (not shown).
- suction speed for each suction fan respective suction area 6, 7, 8, 9 set separately be and it is independent control and / or Control of the suction air flow in each suction area 6, 7, 8, 9 possible.
- Appropriately and in the exemplary embodiment are the individual suction areas through boundary walls 10 made of sheet metal.
- the emerging filaments 3 are in particular in FIG. 2 as well as the direction of flow of the blown air 4 and also the Flow direction of the sucked-in secondary air 11 can be seen.
- the division into different Suction areas 6, 7, 8, 9 both the direction of Blown air 4 and the direction of the secondary air 11 so be influenced that a very reliable and even filament filing is possible and thus surprisingly homogeneous product properties can be achieved can.
- the one arranged behind the main suction area 8 third suction area 9 is used according to the invention for effective Hold the meltblown product on the Ablegesiebband 5.
- the invention lies in the knowledge based on the fact that without this third suction area 9 undesired impairment of the deposited meltblown product through that of the at high speed escaping blowing air sucked secondary air can.
- the division according to the invention into the suction areas 6, 7, 8, 9 minimizes bothersome and unwanted Influences of the air currents.
