The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further described by embodiment.

Embodiment:

See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, device for cutting, extending and shifting elastic waistline comprises frame, cuts off transfer device, drawing mechanism and transfer adhesion mechanism.Cutting off transfer device comprises cut-off rest 16, cut-out rotor 19, cut-outbottom roller 18, cuts offinlet valve 17, adsorption roller inlet valve 13, adsorption roller bearing block 14, absorption roll shaft 15 and adsorption roller 12.

Drawing mechanism comprises a pair of Octoid gear 8; Octoid gear side plate 11 is triangular shape, Octoid gear 8 is located in an inferior horn place of triangular shape Octoid gear side plate 11 by wheel, the place, angle is connecting the positioning sleeve connecting plate 21 of rotatable 90 degree on the triangular shape Octoid gear side plate 11, Octoid gear side plate 11 is connected with positioning sleeve connecting plate 21 by two screws, Octoid gear side plate 11 is provided with an arc groove, one attachment screw is positioned at arc groove, and another is connecting Octoid gear side plate 11 and positioning sleeve connecting plate 21 for the attachment screw of rotating fulcrum.Positioning sleeve connecting plate 21 and positioning sleeve 10 are connected by screw.Positioning sleeve then is enclosed within on the holder 9, can be around axial 360 degree rotations and axial move left and right.Octoid gear side plate 11 1 side lower parts are connecting rope band tensioning plate 7; A pair of Octoid gear 8 is connected on the axle of holder 9 one sides by positioning sleeve 10, sees Fig. 5.

Octoid gear side plate 11 tops one side is equipped with a rope band traction wheel 6, and rope band tensioning plate 7 upper and lower parts respectively are provided with a rope band traction wheel 6; Rope band 20 is " 8 " word shape and installs around on Octoid gear 8 and adsorption roller 12 by three rope band traction wheels 6, sees Fig. 7.

Shifting adhesion mechanism comprises two transferring roller side plates 1, shifts roll shaft 3, transferring roller 4 and transferring roller inlet valve 2.

The roll body outer surface of transferring roller 4 is provided with a rubber layer 5, and the thickness range of rubber layer 5 is the 5-15 millimeter; Transferring roller 4 axial two ends are respectively equipped with transferring roller inlet valve 2,, see Fig. 6.

The operation principle of this device is as follows:

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, when production new model product, at first according to the requirement of product, with two Octoid gears, 8 opened with certain angle, the distance that makes it contact with adsorption roller 12 at 2 satisfies raw-material requirement, and the distance that makes it contact with transferring roller 4 at 2 satisfies tensile requirement.Because fixedly the Octoid gear side plate 11 of Octoid gear 8 can rotate in a circumferential direction as X-axis along Octoid gear holder 9, also can rotate in a circumferential direction as Y-axis around positioning sleeve 10, can also move axially as X-axis simultaneously, so can be very easily that Octoid gear 8 position adjustment are correct along Octoid gear holder 9.After adjusting Octoid gear 8,, rope band 20 tension adjustment are arrived suitable degree by adjusting the adjustment plate of rope band tensioning plate 7 and traction wheel 6.During machine run, elastic waistline is cut off thatbottom roller 18 holds and with cutting offbottom roller 18 motions, with be installed inrotor 19 on blade be cut off when contacting, elastic waistline after the cut-out continues to move to the contact point that cuts offbottom roller 18 and adsorption roller 12 with cutting offbottom roller 18, cut offbottom roller 18 suction and be closed this moment, then produce suction on the adsorption roller 12, elastic waistline is drawn onto on the adsorption roller 12 subsequently, and rotation together thereupon, because be with high-tension rope band 20 on the adsorption roller 12, elastic waistline is placed in rope band 20 tops at this moment.When adsorption roller 12 rotates to Octoid gear 8 contact points, elastic waistline just is pressed on the Octoid gear 8 and with Octoid gear 8 by rope band and rotates, owing between two Octoid gears 8 certain angle is arranged, the distance between them can become big gradually, thereby elastic waistline is stretched.When Octoid gear 8 rotates to when contacting with transferring roller 4, rope band 20 leaves Octoid gear 8, and this moment, Octoid gear 8 tightly was pressed in elastic waistline on the transferring roller 4 with the antiseized rubber layer 5 of high density, because transferring roller about 4 all has inlet valve 2, suction is powerful, and suction is evenly distributed, elastic waistline can firmly be inhaled on transferring roller 4, and with gluing after be bonded together through the lining of transferring roller 4, the quilt cover strip is walked, thereby finishes cut-out, stretching, transfer tasks.
