movable nip rolls 12 move to film amount few position, adapter plate 13 when second detector switch 17 can detect that movable nip rolls 12 move to film amount multiposition, the signal detected is sent to control setup by control setup by the first detector switch 16 and the second detector switch 17 respectively, control setup controls electromagnetic brake 15 and loosens film spool 5 or tension film spool 5.In order to the continuous working of true film chartered plane energy, frame 6 is also provided with the deposit unreeling structure 20 for taking over unreeling structure 1, its structure comprises: for installing the deposit film spool 18 of deposit film volume 19, the two ends of deposit film spool 18 are distinguished in the bearing seat of kinematic support in frame 1, and can rotate in bearing seat respectively, described deposit film spool 18 parallels with film spool 5, deposit film spool 18 is provided with the deposit electromagnetic brake 21 for regulating deposit film volume 19 to unreel speed, when lay in unreeling structure 20 take over unreeling structure 1 work time, the signal detected can be sent to control setup by the first detector switch 16 and the second detector switch 17 respectively, control setup controls deposit electromagnetic brake 21 and loosens film spool 5 or tension film spool 5.For the ease of by the film on deposit film volume 19 be about to unreel the film that complete film roll up on 4 and bond fast, lay between unreeling structure 20 and unreeling structure 1 and be provided with the film bonder 24 that film can be bondd mutually.In addition, frame 6 between guiding roller mechanism 2 and traction stocking mechanism 3 is provided with film cutting mechanism, described film cutting mechanism comprises cutting knife 26, first film guiding roller 27 and the second film guiding roller 28, the down-bite jaw of cutting knife 26, first film guiding roller 27 is positioned at the top of cutting knife 26, higher than the height of cutting knife 26 cutting edge at the bottom of the roller of the second film guiding roller 28, the film 7 of being derived by guiding roller mechanism 2 can lead directly to enter in traction stocking mechanism 3 through the first film guiding roller 27 and maybe can also enter in traction stocking mechanism 3 through the second film guiding roller 28 guiding after cutting knife 26 cuts; When on film volume 4 or deposit film volume 19, the width of film is the parcel width of one group of plastic bottle, the film 7 of being derived by guiding roller mechanism 2 directly enters in traction stocking mechanism 3 after just being led by the first film guiding roller 27, when the film on film volume 4 or deposit film volume 19 is the parcel width of two groups of plastic bottles, enter in traction stocking mechanism 3 through the second film guiding roller 28 guiding again after the film of being derived by guiding roller mechanism 2 just needs first to be cut by cutting knife 26, being arranged so that of film cutting mechanism unreels the film that draw gear is applicable to different in width.
Principle of work is as follows: during the work of film chartered plane, film 7 is constantly consumed the film 7 impelling film spool 5 to be constantly rotating film is rolled up on 4 and unreels, unreeling the film the got off guiding roller 8 be constantly directed in roller mechanism 2 is directed in traction stocking mechanism 3, film 7 is wound in serpentine interval after on nip rolls 9 in traction stocking mechanism 3 and movable nip rolls 12 and exports from traction stocking mechanism 3, film 7 tensioning between adjacent nip rolls 9 and movable nip rolls 12 under the elastic force effect of the spring 14 at two ends, the film 7 that is fed forward can drive activity nip rolls 12 respectively in the chute 11 of correspondence on, lower slider, less once the film amount in traction stocking mechanism 3, namely when movable nip rolls 12 move to film amount few position, first detector switch 16 can detect the adapter plate 13 of this position, the signal detected is sent to control setup by the first detector switch 16, control setup controls electromagnetic brake 15 and loosens film spool 5 in time, namely reduce the rotary resistance of film spool 5 and accelerate the speed that unreels of film spool 5, thus the storage capacity of the film 7 drawn in stocking mechanism 3 is increased gradually, so just can effectively prevent the storage capacity of the film 7 drawn in stocking mechanism 3 very few, once traction stocking mechanism 3 in film amount more, namely movable nip rolls 12 move to film amount multiposition time, second detector switch 17 can detect the adapter plate 13 of this position, the signal detected is sent to control setup by the second detector switch 17, control setup controls electromagnetic brake 15 tension film spool 5 in time, namely increase the rotary resistance of film spool 5 and slow down the speed that unreels of film spool 5, thus preventing the storage capacity of the film 7 in traction stocking mechanism 3 is too much.Deposit unreeling structure 20 replaces principle of work during unreeling structure 1 the same, does not repeat them here.
Advantage of the present invention is: on film spool, be provided with electromagnetic brake, frame is provided with the first detector switch and the second detector switch, adapter plate in adapter plate when first detector switch and the second detector switch can detect the few position of film amount in traction stocking mechanism respectively and traction stocking mechanism during film amount multiposition, and respectively the signal detected is sent to control setup, control setup controls electromagnetic brake and loosens film spool or tension film spool in time, just can effectively avoid in such traction stocking mechanism the very few or too much situation of film amount occurs, thus substantially increase the stationarity of film conveying in film chartered plane working process.
