Description
Technical field
The present invention relates to a kind of belt conveyor of equipment of the lamination coating of reeling, described lamination coating has the non-woven medium that is positioned on the core or the form of volume, wherein said core is rotatably fixing to twine volume so that form, endless belt conveyer is along the zone circle directed movement around described core and some rotaring forward rollers, at least one and actuating device link in the described rotaring forward roller, also have one to link with tightening device at least.
Background technology
Disclose this winding apparatus that twines volume that is used for producing among European patent EP-A2-878 568, wherein twined volume and form by flat belt conveyor.With a circle belt conveyor be arranged in a core pipe (core) around, the core pipe is rotatably installed on the anchor shaft, tape turns can increase and adjust its size along with twining coil diameter, when the end of winding process, almost completely be centered around twine volume around.Twine volume in order to form, fleece (web) enters the tape turns between two rotaring forward rollers and is placed on the surface of core pipe.
Each side at the core pipe is provided with the reel coaxial with it so that support fibroreticulate side in winding process.Because this supporting role, the winding that twines in winding process volume can form neat surface.By between the belt conveyor that guides between two reels and this reel inside face very little distance being arranged.
In order to prevent that the belt conveyor between the reel from producing displacement and fiber is stopped up, suggestion is provided with the surface configuration that can be meshed with the correspondingly-shaped on the rotaring forward roller in the above-mentioned patent on the belt conveyor surface that contacts with rotaring forward roller.Take this measure can prevent that the belt conveyor between the reel from producing cross travel.Have only the fibroreticulate fringe region of less fiber buddle to pull out, it has also reduced the pollution to belt conveyor, especially edge region.Hope is improved the surface of formed winding volume by this measure.Yet the fringe region that twines volume still chimb can occur, and this is produced by system in the winding increase process of twining volume.In winding process, the thrust that is produced by belt conveyor can make lamination coating surrender the fringe region of winding volume or the reel place on next door.This makes that being positioned at the belt conveyor marginarium counter pressure that twines the roll edges zone increases, and the result can make this regional belt conveyor be deformed into waveform.Therefore, uneven marginarium can appear in the winding volume, because the pressure that belt conveyor is applied on the winding volume skin in this fringe region is uneven.
For fear of this phenomenon (the wavy distortion of belt conveyor), in the Swiss Patent application CH-1105/00 on June 5th, 1, propose to make the extensibility of belt conveyor two side areas (when belt conveyor is vertically seen) to be lower than the extensibility of belt conveyor zone line.Suggestion adds more fibrous bundle (pulling force bundle) to prevent the projection of belt conveyor in the inflexion point zone specially at the fringe region of belt conveyor.Though this proposal is improved the inflexion point zone, especially for rotaring forward roller, it can not solve the problem that fringe region occurred in twining volume formation process.
Summary of the invention
The objective of the invention is to avoid the shortcoming of perception method in above-mentioned the sixth of the twelve Earthly Branches, and propose a kind of device, can be by the winding volume that uses production of machinery that volume is twined in belt conveyor production go out to have neat flat edges part.
For this reason, the invention provides a kind of belt conveyor of the lamination coating equipment of reeling, described lamination coating has the non-woven medium that is positioned on the core pipe or the form of volume, it is rotatably fixing to be used to form the described core pipe that twines volume, endless belt conveyer is along the zone circle directed movement around described core pipe and some rotaring forward rollers, at least one rotaring forward roller in the described rotaring forward roller is connected with actuating device, another rotaring forward roller at least in the described rotaring forward roller links to each other with tightening device, it is characterized in that, the manufactured materials of described belt conveyor or its inner structure make this belt conveyor transverse to the bending modulus on the direction longitudinally greater than 249 MPas.
In order on combing machine, to make further subsequent treatment, a kind of smooth winding volume must be provided, it has fleece all very smooth on whole width.In order to reach this purpose, suggestion is in the equipment of lamination coating that is used for reeling, and bending modulus should be greater than 243 MPas on the direction longitudinally transverse to it for belt conveyor.Preferably, bending modulus can be between 250 to 330 MPas (megapascal (MPa)).
Bending modulus can be equal to modulus of elasticity, and is a correlative factor determining belt conveyor bending stiffness or flexural rigidity.
The bending stiffness of the belt conveyor sample that one side is fixing can obtain from following formula:
Wherein, c=bending stiffness; The L=specimen length; The E=bending modulus; The geometrical moment of inertia of I=sample.
There is the belt conveyor of this bending stiffness can prevent that the belt conveyor of fringe region in twining volume formation process from bending by use.But also can prevent that the belt conveyor in this zone from producing corrugated distortion.Therefore belt conveyor can be arranged in such a way, that is, because the antagonistic force that material displacement produces can absorb on the whole width of conveyer structure.
Though the horizontal bending stiffness or the flexural rigidity of belt conveyor have improved, and can smoothly turn on rotaring forward roller in order to ensure belt conveyor, the longitudinal bending modulus of also advising belt conveyor is less than the cross bending modulus.Like this, longitudinal bending modulus can be between 200 to 280 MPas.
A kind of belt conveyor of compound type is preferably used in suggestion, has at least one and is clipped in tensile layer between two tissue layer or the plastic layer.These three layers all firmly also can not link together dividually.
Be used for transmitting the tensile layer that is applied to the belt conveyor upper pulling force such as can making, and preferably make with polyamide with one layer or more plastics or multiply plastic cord.
Tissue layer or plastic layer are mainly used to absorb or offset the antagonistic force that produces such as making with polyamide fabric in the fringe region that twines volume.Also advise at least one surface of belt conveyor, establishing a wear-resistant and anti-incised layer,, be used for improving the service life of belt conveyor and prevent that fiber from adhering to such as making with polyurethane.Have good guidance in order to ensure transmission around rotaring forward roller, also suggestion adds one deck such as the elastic carrier layer made from rubber or natural rubber on a tissue layer therein, and this covers the tissue layer that one deck is made with plastic material in addition again above elastic carrier layer.
For the belt conveyor that makes between reel the zone can lateral guide to, suggestion adds the special-shaped layer of one deck again on above-mentioned other one deck tissue layer.Described special-shaped layer can be made with polyurethane, can cooperate with the correspondingly-shaped on the rotaring forward roller, and tape turns is extended downwards from rotaring forward roller, thus the lateral guide that can guarantee belt conveyor to.
Because the bending modulus that proposes according to the present invention can realize higher flexural rigidity, so just might replace above-mentioned special-shaped surfaces to carry out lateral guide with other guiding parts can lean against on these guiding partss and can not produce transverse to the crooked of throughput direction or protrude to, the fringe region of belt conveyor.
