The present invention includes one group arrange continuously, and can be with the polynary conveying device of friction speed transmission, these conveyers can be done forward backward operation according to throughput direction, roller mechanical device is located at this top of organizing polynary conveying device, its roller can both rotate around axle separately, and can move along the annular roller subchannel.Feed between conveying device and roller mechanical device, material can be from arbitrary end feeding of transfer passage, in order that repeated stretching operation simply.
Introduce embodiments of the invention now.
Roller mechanical device 23 is contained in above the conveyer, it comprises one group of polynary roller 33, and each roller in the polynary roller 33 all freely is erected on the axle 35, chain belt 37 stretches under the tension force between the sprocket wheel 25 and 29 that is loaded on respectively on the axle 27 and 31, sprocket shaft is contained on the shelf 39 of this device successively, after axle 35 was fixed on the chain belt 37, it was just along with chain belt 37 motions, and polynary roller 33 is also just along with chain belt 37 rotates together.The speed of the movement velocity of chain belt 37 and the roller 33 that and then rotates is often set for more faster than any the speed in conveyer 3 and 13.Track 47 can be contained on the shelf 39 of this device, can at the either side of feed surface.
Roller mechanical device 23 and conveyer 3 and 13(Figure 1B) transfer passage between slit H can be along with the varied in thickness of institute's stretching material 1.For reaching this purpose, the vertical conveyor 41 that is contained on the shelf 39 is holding in the palm roller mechanical device 23, and lift just can make roller mechanical device 23 liftings.
Narrate the operation and the effect of apparatus of the present invention now.
When conveying device forward during transmission, the length velocity relation between them is such, and the speed of first conveyer 3 is lower than the speed of second conveyer 13.For this reason, as shown in Figure 1, the plastic material 1 of certain-length rests on the conveyer 3, and be transported to the straightway place of roller mechanical device 23 bottoms, during material 1 was transported on second conveyer 13 that, material 1 was just stretched by pulling force that is caused by first conveyer 3 and 13 speed differences of second conveyer and the rolling pressure that is given by roller 33 simultaneously.When the afterbody of plastic material 1 passed through roller mechanical device 23, first conveyer 3 and second conveyer 13 were with regard to stop motion, and decline roller mechanical device 23 is to reduce slit H.Make conveyer 3 and 13 break-ins operation by conversion motor 11 and 21 direction of rotation, make the speed of velocity ratio second conveyer of first conveyer 3 fast simultaneously.These adjustment will make plastic material 1 break-in campaign, and it is transferred the pulling force that the speed difference of 13 of machine 3 and conveyers produces simultaneously and the rolling pressure that is given by roller 33 is stretched.Plastic material 1 therefore and attenuation, this has nothing to do with the traffic direction of roller 33 along annular channel.Like this, just can replace with a simple device and make repeated stretching backward forward and demonstrate its significant drawing effect.
Roller mechanical device 23 of the present invention can be given plastic material 1 rolling pressure, and the traffic direction of this and roller 33 is irrelevant, because roller 33 is faster than any speed of conveyer 3 and conveyer 13 usually along the linear motion speed of transfer passage.Because this speed difference, no matter whether the throughput direction of conveyer changes, always the roller 33 that rotates around axis is in same turning to separately, therefore, the work relationship that roller 33 and conveyer 3 and conveyer are 13 is constant, and just the roller relative running speed of swaying is variable.Do not have tangential strain in the plastic material 1, and just minimum strain is just being arranged when its axle separately rotates at path operation and roller 33 along roller 33.Even save track 47, make roller 33 by rotating with the friction of plastic material 1, also can observe this fact.It is reasonable using track 47, but does not have track good.If without track 47, then roller 33 contact with regard to handy and plastic material surface generation friction fixed speed rotate.
As shown in Figure 3, apparatus of the present invention can provide one group of polynary roller 45 as conveying device.Forward during transmission, roller 45 is rotated by motor 43 is lower than conveyer 13 to be higher than conveyer 3 speed at conveyer.Equally, when conveyer backward during transmission, roller 45 is lower than the speed of conveyer 3 and comes transmission to be higher than conveyer 13.As the embodiment shown in Fig. 1 (A), it can obtain same drawing effect.
In addition, as shown in Figure 6, adopt a predetermined angle to make the transfer passage of roller mechanical device 23 relative conveyers produce an inclined angle alpha, can obtain significant drawing effect like this.For example,, comprise a worm screw 59 by a worm gear pairs, worm gear 57 and handgrip 61, it just can make roller mechanical device form inclination, sees shown in Figure 7.
As a given α angle, plastic material that just can big thickness or material sheet feed in the slit between roller mechanical device 23 and conveyer.Can also adjust the transporting velocity of each conveyer, make that big speed was moved when the conveyer output was can be enough more parallel with conveyer than roller mechanical device 23, this has just correspondingly increased the stretch capability of this device.
When in a single day plastic material piece or material sheet be stretched, roller mechanical device just can change its obliquity.Material can be folded increases thickness, feeds in the slit below the roller mechanical device 23 again, according to the relative velocity of the throughput direction of readjusting conveyer and every conveyer, oppositely repeats to stretch.If the plastic material that stretched multi-layer is inferior, as alternately put into cream or margarine layer in multi-level object, repeated stretching and folding operation will increase its interlayer number effectively.
In addition, adjust the absolute altitude of every conveyor delivery passage individually, also can obtain same effect.
