The present invention be a kind of be base material with the netted flat filament of plastics, longitude and latitude right angle Orthogonal Composite becomes the method and the unit mahine of plastics Nonwovens.Existing longitude and latitude Orthogonal Composite machine carries out on horizontal plane mostly, the netted flat filament of its broadwise is after cutting off along the direction vertical with the warp-wise net that advances continuously, must be with one piece piece, and horizontal feed is to the netted flat filament of warp-wise, carry out the right angle quadrature, be thermal bonding to and be Nonwovens.
Longitude and latitude of the present invention right angle quadrature is combined method and the unit mahine that utilizes the right angle quadrature that the conversion of locus carries out, and this method can make moulding process and establish each and simplify greatly.
Description
The present invention is that a kind of warp, the netted flat filament of latitude carry out Orthogonal Composite shop, right angle method and unit mahine repeatedly.It is characterized in that the cancellated flat filament that to make through the crystalline thermoplastic material of warp-wise uniaxial tension, on the plane of vertical (vertically), carry out quadrature shop, right angle as the longitude and latitude wire rod respectively and change, then heat bonding and become and have network structure and the on all four plastics Nonwovens of intensity in length and breadth.
Existing technology is Japanese Process Technology of Polymer research institute has successfully created a kind of S-50 type in 1975 a longitude and latitude right angle Orthogonal Composite machine, and the basic process that this combination technique has obtained this unit mahine of United States Patent (USP) (US, PUt 4052242) is:
1. the conveying of the netted flat filament that cut off of broadwise need move up and down and shuttling movement and piece of the netted flat filament of broadwise is picked up by means of the elasticity rotating belt of picking up toughness liquid is well-regulated, and be transferred with the revolution of tape loop, be fitted on the netted flat filament of warp-wise of coming from following traction, enter into pre-bond roll together, work as warp, the netted flat filament of broadwise pre-bond roll carry out preliminary bonding after, also need to wash to remove viscous liquid, also to remove moisture content, send into heat combined roller then and carry out heat bonding, so operation is many.
2. stretched later netted flat filament is thin and light, is picking up the space, disarrays easily in the transportation on the horizontal plane.Influence the regularity of product, and travelling speed is restricted.
The objective of the invention is to adopt and a kind ofly picked up the netted flat filament of broadwise, and can successively carry out longitude and latitude Orthogonal Composite shop method and device repeatedly without mucus.
The method that the present invention adopts with method dissimilarity in the past is: technology in the past all is that direction upper warp and woof net at horizontal plane is mutually the right angle and carries out the orthogonal shop repeatedly, and the inventive method is to carry out the orthogonal shop repeatedly on the plane of vertical (vertically), promptly utilizes the difference on the space to realize picking up sticking purpose without viscous liquid.
The present invention has studied overall process and all actions repeatedly of longitude and latitude orthogonal shop, repeatedly method and apparatus of a kind of new Orthogonal Composite shop, right angle has been proposed, and the more important thing is to have caught and cut off and transfer among two critical processes, transfer this key link, speeded up because transfer, the whole shop speed that changes has been accelerated greatly.
The present invention adopts following method to accelerate to cut off and handover speed:
1. adopt a kind of cutting tool of efficient high-speed to carry out the continuous cutting-off of the flat silk screen of broadwise.Cutting machine shown in figure one, its cutter (14) is to be made by a steel alloy, both sides electric heating bar (15) and edge hot material (16) clamping, be fixed on then on the rotatable knife rest (17), the rotary speed of knife rest equals the transporting velocity of latitude net, when the edge of a knife (14) rotates to the contact latitude when online, the latitude net compresses between asbestos rubber cushion block (18), owing to being subjected to the cutter heating, the latitude net melts, clamping conveying roller (5 in addition, 7) speed difference produces pulling force and cuts off, cutter revolves to turn around and just equals to cut off the length of a latitude net, just equals the width of warp-wise net.The swivel mount direction of rotation is consistent with the netted flat filament traffic direction of broadwise.Cutting off later latitude net piece is removed by conveyer belt (19) level immediately, because above-mentioned front and back niproll (5,7) rotating speed is poor, the rotating speed that is about to back niproll (7) is slightly larger than front nip rollers (5), so the netted flat filament of broadwise has certain force of strain will break away from cutter fast once cutting off, so can not produce sticking cutter phenomenon, in order to guarantee to cut off the reliability of latitude net.The cutting knife surface temperature generally is not less than 260 ℃, and heating power is no less than 2KW.
2. be to take to transform to the transfer movement that vertical direction is carried out the netted silk of broadwise to the method for transporting of the netted silk of the broadwise of having cut off among the present invention from horizontal direction, the broadwise net that has soon cut off changes traffic direction through slide plate (12) and reversing plate after being transported to the end of conveyer belt (19), promptly turning to vertical hanging from level falls, when the moment that is about to all break away from the unsteady nip rolls (11) of conveyer, by the briquetting (27) of coming from dead ahead pushing with the upper end pressure holding of broadwise net on the netted flat filament of warp-wise of vertically operation, the netted flat filament of warp-wise is to be close to be combined on the vertical slide plate (28) (metallic plate), briquetting simultaneously along with the netted flat filament of warp-wise (29) motion fast from moving the transporting velocity synchronised that the speed of service of the flat silk screen of warp-wise and broadwise are netted.When the pressure holding piece with the pressure holding of broadwise twine on the netted silk of warp-wise the time, the broadwise twine that another piece cuts off is followed (almost being simultaneously) again and is hung downwards and fall.It should be noted that the pressure holding piece with the pressure holding of the netted silk of warp-wise when vertical slide plate (28) is gone up, fall allow some leeway (space) fast for a broadwise net afterwards.Another piece pressure holding online and handover rapidly of when latitude net piece falls near end, being come by the front pushing again at warp-wise.So constantly repeat, the do action of " falling-pressure holding-transfer-fall " has been realized the purpose of transferring at a high speed.When the netted silk of each piece broadwise is transferred and vertically fallen after the position of longitude and latitude quadrature along with the pressure holding piece, above the pressure holding piece, still leave stretching out of 50～100mm at the netted silk of the broadwise of pressure holding piece upper end, promptly by barbed up pressing tape loop (24) clamping of device, after the whole clampings in the upper part of a net finish, pressure holding piece (27) promptly loosens automatically, leave the netted silk of broadwise, and be turned back to the beginning pressure holding perpendicular position, carry out the pressure holding of next piece latitude net piece, and one connect one and be fitted in pre-bond roll (21) that vertical warp-wise enters into a pair of arranged vertical together along with the warp-wise net on the net and be heated the preliminary bonding of back low melting point layer fusing graticules and get up to become Nonwovens.By seeing shown in the figure two by the preliminary bonding Nonwovens of pre-bond roll (21), along direction of advance, progressively be shown laid flat in the first sticking Nonwovens that advances along the horizontal plane direction by horizontal nip rolls (22), and then wrap tightly under the condition by the plain cloth (32) of nip rolls (23) and circulation that low melting point layer through, the netted silk of latitude is melt into one fully and cooled and solidified becomes the plastics Nonwovens, again behind chill roll (33) cooling and edge-trimming cutter (34) excision burr, be wound into tube by winder (35), promptly become the Nonwovens finished product.
Because the present invention need not to apply viscous liquid, need not processes such as clean dry again, so can be referred to as repeatedly method of vertical dry type combination shop, its device is called vertical longitude and latitude right angle Orthogonal Composite machine or machine for cross-laying.
Figure three is pressure holding piece slew gear schematic diagram, the pressure holding piece is by being unified into a rotating belt with chain link (41) and chain (42) between the bent stick (39), rotating swiveling wheel (36) should be designed to polygon, so that operating steadily of each chain link, before the pressure holding piece runs to the position of vertical quadrature and leave the centre of the netted silk of warp-wise, be provided with between a track (37) and the pressure holding piece in alignment.When a row pressure is held piece (width equals the width of broadwise net) when being in vertical quadrature position, by one that is arranged on pressure holding piece bent stick bottom rotating promotion wheel (45) bent stick bottom (44) are located to push to can make the top rubber pressure holding piece (38) of bent stick rely on the broadwise net on one side, with the pressure holding of latitude net, the slippage in the chute (46) that promotes wheel (45) of curved bar bottom this moment, slippage (46) length equals the width of broadwise net, after leaving chute, the bent stick bottom promptly enters in the fixing chute (46A) till the pressure holding piece leaves the warp-wise net, very the most important thing is promotes wheel (45), the moving cycle once of revolution has just equaled broadwise net piece and has vertically fallen the time that is over, secondly, when row's bent stick is promoting to slide in the wheel chute, and then slippage in the chute (46B) of row's bent stick directly over promotion wheel (45), have only when last row's bent stick walk to be over chute (46A) thus after moment rotate one row bent stick bottom (44), back be pushed, make pressure holding piece (38) pressure holding broadwise net.So repeat to carry out continuously.
The embodiment of longitude and latitude combined method and process is as follows:
The netted flat filament volume (1) that one volume is made by high low density polyethylene (LDPE) laminated film is used as the broadwise net, be placed on and unreel on the unwinding rack because the draw of preceding conveying roller (5) is introduced into hot treatment tub (3), after netted silk typing is put in order under heating condition, through chill roll (4), be admitted on the conveyer belt (19) of level.Two pairs of conveying rollers (5 that keep a constant speed difference before and after establishing on it, 7) in fact be exactly a pair of jockey pulley, (5,7) two roller middle devices a rotating cutter swivel mount (6) and are whenever circled and can cut into the broadwise net that length is the width of warp-wise net, a cutting tool and a netted silk asbestos packing sheet of lower liner (18), after the broadwise net is cut off, produce the tension force of a tension owing to the speed discrepancy of front and back conveying roller, cut broadwise net and the broadwise net that does not cut off are separated, and the terminal arc skateboard (12) that is transported to conveyer belt is located, at this moment the top of latitude piece freely falls downward vertically, but end still in unsteady niproll (11) clamping, make monoblock latitude net become suspension type.When latitude net piece be about to break away from floats niproll (11) moment, advanced from the conveyer belt dead ahead come one can rotating soft pressure holding piece (27) with the upper end pressure holding of broadwise net piece, for leaving the space for next latitude net piece, meanwhile float nip rolls (11) almost with the pressure holding of pressure holding piece (27) time, push broadwise net piece to the online And of the warp-wise origin-location of ging up rapidly, the upper end is left not by 5～10 centimeters broadwise nets of pressure holding piece (2) pressure holding.The warp-wise net (29) that vertically unreels and move is close on the smooth flat board (26) and is unreeled continuously, the pressure holding piece with by the latitude net piece of pressure holding along with the operation of warp-wise net the position of the vertical pressure holding that speeds away synchronously, this moment, another piece latitude net piece freely hung again under the land near the end, again by another piece advance from the dead ahead pressure holding that comes online at warp-wise, and promptly leave the position of vertical hanging.The latitude net piece that cuts off continuously comes out from conveying roller like this one by one, and one then one hanging freely and falling, with again constantly one connect one and the position of leaving vertical hanging by pressure holding, be fitted in one by one on the plane of vertical warp-wise twine and be mutually the right angle orthohormbic structure.Because still there is not 5～10 centimeters netted flat filament the upper end of broadwise net piece by the position of pressure holding, after leaving the vertical hanging position at the beginning, latitude net piece just is set at barbed circulation clamping band (23) clamping of the netted flat filament upside of warp-wise immediately, when the upper end of whole latitude net piece is held when finishing, the pressure holding piece is just transported on the position of getting back to original pressure holding by gyroscope wheel (36), carry out the pressure holding action of following one-period, the pre-bond roll (21) that the netted flat filament of longitude and latitude that the shop is repeatedly good enters into the interior heating of a pair of arranged vertical immediately makes the low melting point layer of the netted flat filament of longitude and latitude melt preliminary or the bonding Nonwovens that becomes of part, then preliminary bonding Nonwovens is progressively done commutation back, 90 ° of angles from vertical direction by the deflector roll (22) of commutation and is moved to horizontal direction, and enter into a large-area heat bonding roller (26), be heated under 110～120 ℃ of temperature conditions, the low melting point layer melts fully, because the low melting point layer that makes graticules of exerting pressure of circulation plain cloth (30) is melt into one with wrapping tightly even action, through chill roll (31,33) cooling curing, after edge-trimming cutter (34) is cut edge, become by winder (35) rolling and to have the plastics Nonwovens of longitude and latitude two to the consistent network unanimity of intensity.
