The specific embodiment
As shown in Figure 1, the utility model is that a kind of plastic bag is pulled apart device, it mainly by frame 1, pull apart motor 2, fixed electrical machinery 3, pull apart rubber roll group 4, fixedly rubber roll group 5, synchronous pulley 61, synchronous pulley 62, pull apart cylinder 7, fixedly cylinder 8, cylinder erecting frame 91, cylinder erecting frame 92, go up gas blow pipe 101 and following gas blow pipe 102 is formed.
The described motor 2, fixed electrical machinery 3, cylinder erecting frame 91, cylinder erecting frame 92 pulled apart all is installed on the frame 1.
Describedly pull apart the top that cylinder 7 is installed in cylinder erecting frame 91, fixedly cylinder 8 is installed in the top of cylinder erecting frame 92; Describedly pull apart rubber roll group 4 and fixedly rubber roll group 5 adjacent settings.
The described rubber roll group 4 of pulling apart is by initiatively pulling apart rubber roll 41 and the driven rubber roll 42 of pulling apart constitutes.It is relative up and down and establish with the driven rubber roll 42 of pulling apart initiatively to pull apart rubber roll 41, driven pull apart rubber roll 42 rotatable be installed on the cylinder erecting frame 91 and with stretch the piston rod 71 that gets off from cylinder erecting frame 91 tops and be connected, under the drive of piston rod 71, can move up and down; Pull apart initiatively that rubber roll 41 is connected with the output shaft of pulling apart motor 2 by synchronous pulley 61, chain 63, sprocket wheel and drive by pulling apart motor 2.
Described fixedly rubber roll group 5 by initiatively fixedly rubber roll 51 and driven fixedly rubber roll 52 constitute, initiatively fixedly rubber roll 51 is relative up and down with driven fixedly rubber roll 52 and establish.Driven fixedly rubber roll 52 is rotatable be installed on the cylinder erecting frame 92 and with stretch the piston rod 81 that gets off from cylinder erecting frame 92 tops and be connected, under the drive of piston rod 81, can move up and down; Initiatively fixedly rubber roll 51 is connected with the output shaft of fixed electrical machinery 3 by synchronous pulley 62 and is driven by fixed electrical machinery 3.
As shown in Figure 5, described cylinder erecting frame 92 mainly is made up of portal 921, pilot bar 922, guide holder 923, rubber roll erecting frame 924.Described pilot bar 922 is installed on the portal 921, and rubber roll erecting frame 924 slips on pilot bar 922 by the guide holder 923 of its both sides, driven fixedly rubber roll 52 rotatable being installed on the rubber roll erecting frame 92.The structure of cylinder erecting frame 91 and cylinder erecting frame 92 are basic identical, repeat no more.
In the present embodiment, described pull apart cylinder 7 and fixedly cylinder 8 have two respectively, two pull apart cylinder 7 and two fixedly cylinder 8 be installed in the top of two countercylinder erecting frames, 91,92 portals 911,921 respectively, pull apart the piston rod 71 of cylinder 7 and fixedly the piston rod 81 of cylinder 8 to pass the top of portal 911,921 separately respectively affixed with rubber roll erecting frame 914,924 separately.
The described motor 2 of pulling apart adopts three phase asynchronous motor 2; Described fixed electrical machinery 3 adopts servomotor 3.
With reference to shown in Figure 2, the described gas blow pipe 101 of going up is installed on the portal 921 of cylinder erecting frame 92, and following gas blow pipe 102 is installed on the frame 1 by following gas blow pipe mount pad 103.Between two pairs of rubber rolls, plastic bag passes between last gas blow pipe 101 and following gas blow pipe 102, because plastic bag is soft, can nature sagging from pulling apart after rubber roll group 4 output, so use gas blow pipe 101 and following gas blow pipe 102 plastic bag is blown afloat, thereby fall on the load-transfer device 10 afterwards and be stacked in the top of previous plastic bag.
Principle of work of the present utility model:
With reference to shown in Figure 2, in the process of producing, film is before entering the winder of saying good-bye as Fig. 3, Fig. 4, and each sack can be divided by the some broken string, applies certain power and can tear separately.Film is through behind the film guiding roller 20, and guiding enters the utility model.In process of production, at first film being worn film according to the projected path mode places, produce then, at this moment, the driven rubber roll 42 of pulling apart of pulling apart rubber roll group 4 that is arranged in the top is to be in hanging shape when plastic bag normally moves, promptly do not contact, have only in the time will pulling apart, just to promote the driven rubber roll 4 of pulling apart and down move, contact with bag by the effect of pulling apart cylinder 7 with plastic bag.When entering, a broken string pulls apart rubber roll group 4 and fixedly between the rubber roll group 5, fixed electrical machinery 3 lockings or deceleration, and fixedly rubber roll group 5 stops operating or speed reduces, and remains a speed and carries out running work and pull apart rubber roll group 4.Because fixedly rubber roll group 5 is not rotated or the speed reduction, film is applied in a power, is torn apart from a broken string, divides from film, enters into load-transfer device 10, delivers to wrap-up 30(as shown in Figure 6).After film was torn, fixed electrical machinery 3 remained in operation, and drove fixedly rubber roll group 5 rotations, film is sent to pulls apart rubber roll group 4, sent from pulling apart rubber roll group 4, and gas blow pipe work is up and down arranged simultaneously, can guarantee smooth the falling on the load-transfer device 10 of a back film.Meanwhile.The load-transfer device 10 of pulling apart rubber roll group 4 and its left side all is that the speed that keeps certain is constant all the time, and the speed when fixedly rubber roll group 5 is restarted work after pulling apart can be faster than pulling apart rubber roll group 4, make a back plastic bag catch up with previous plastic bag, thereby it is stacked on the previous plastic bag.So repeat continuous firing.
