The height of driven voller can regulate, and by regulating the height of driven voller, gap between driven voller and drive roll and the thickness of BOPP film is matched, and this transverse stretching machine draw-gear can be drawn the BOPP film of differing heights.The elastic force of two pairs of springs and driven voller and to hang over the weight of the parts on driven voller basic identical, play balance, unsteady effect, the setting of spring, conveniently in the time of maintenance or while drawing thicker BOPP film, lift driven voller, facilitate the adjusting of bolt, according to the thickness of BOPP film simultaneously, screw bolt, make driven voller be positioned at a reasonably height, by the bolt location that is connected, simple in structure.
In above-mentioned a kind of Height Adjustable transverse stretching machine draw-gear, the cross section of described installing hole is convex shape, comprise aperture and the larger macropore of width that width is less, the cross section of described bearing also and convex shape, comprise head and the larger bottom of width that width is less, the width of described head and the width of aperture match, and the width of described bottom and the width of macropore match.This kind of structure, driven voller position in the horizontal direction can not be offset, the peak of drive roll is corresponding with the minimum point of driven voller, can better draw BOPP film, and this kind of structure plays the effect of guiding, driven voller, in the time regulating height, can not tilt, more can deviation post, degree of regulation is high.
In above-mentioned a kind of Height Adjustable transverse stretching machine draw-gear, described a pair of spring is symmetrical arranged with the centerline axis of installing hole vertical direction.Be symmetrical arranged, elastic force is even, reasonable in design.
In above-mentioned a kind of Height Adjustable transverse stretching machine draw-gear, described upper rack has the mounting blocks of protrusion, in described mounting blocks, has installing hole.The existence of mounting blocks facilitates bolt to regulate.
In above-mentioned a kind of Height Adjustable transverse stretching machine draw-gear, the quantity of described drive roll is 2-4, and the quantity of described driven voller is also 2-4.Quantity is according to actual conditions setting, but the quantity of drive roll and driven voller is equal, is one to one.
In above-mentioned a kind of Height Adjustable transverse stretching machine draw-gear, described motor is servomotor.Servomotor is conventional motor.
Compared with prior art, this Height Adjustable transverse stretching machine draw-gear has the following advantages:
1, this draw-gear draws the BOPP film that will enter transverse stretching machine cross directional stretch, BOPP film is moved smooth and easy, and the height of draw-gear can regulate, the height that regulates driven voller according to the BOPP film of different-thickness, makes this draw-gear all can draw for the BOPP film of different-thickness.
2, this draw-gear carries out determining height by the locking of bolt and bearing block to driven voller, simple in structure, easy to adjust.
3, the width of the bearing block of this draw-gear and the transverse width of installing hole match, and make bearing block not understand left and right skew, make the driven voller can horizontal-shift, the precision when improving bolt simultaneously and regulating.
