Embodiment
With reference to specific embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of paper extraction packaging film beats mouth tearing device, including frame 100, is pacified in frame 100 by bearing
Equipped with magnetic roller 10, bottom knife roller 20 and drive roll 30, between magnetic roller 10, bottom knife roller 20 and drive roll 30 along straight line from top to bottom
Arranged adjacent successively, the gap passed through for packaging film is left between magnetic roller 10 and bottom knife roller 20;Magnetic roller 10, the and of bottom knife roller 20
The same side of drive roll 30 is respectively equipped with first gear 1, and adjacent first gear 1 between the two is intermeshed;The bottom of frame 100
Portion is fixed with servomotor 40, and the opposite side of drive roll 30 is provided with second gear 2, and second gear 2 passes through belt 3 and servomotor
40 drive connections;The band of magnetic roller 10 is magnetic, the intensity of magnetic with do not influence the motion of magnetic roller 10 and adjacent bottom knife roller 20 but
And can is enough adsorbed tearing notch blade 50 and set for standard, by magnetic is adsorbed replaceable tearing notch blade 50 in magnetic roller 10
On, tearing notch blade 50 is metal blade, has the blade of different size shape on different tearing notch blades 50, can be on packaging film
Leave the tearing notch of different size shape.
During work, corresponding tearing notch blade 50 is directly adsorbed on magnetic roller 10 according to the requirement of the tearing notch of packaging film,
Packaging film is placed in the gap between magnetic roller 10 and bottom knife roller 20, and servomotor 40 drives drive roll 30 to be rotated, main
Dynamic roller 30 drives bottom knife roller 20 and magnetic roller 10 to rotate by gear 1 again, in the rotation process of bottom knife roller 20 and magnetic roller 10,
Tearing notch is stamped on packaging film by tearing notch blade 50.
Further, magnetic roller 10 is provided with the blade fixed bit 11 being consistent with the shape of tearing notch blade 50, tearing notch blade 50
Magnetic suck is fixed on blade fixed bit 11 by the positioning of blade fixed bit 11, can be easy to the installation of tearing notch blade 50 and be consolidated
