Specific embodiment

It please join shown in Fig. 1 to Fig. 5, the utility model discloses a kind of diaphragm cutting machine, for cutting barrier film base material 700 The diaphragm strip 710 of Cheng Duogen strip comprising unreeling structure 100, cutting mechanism 200, rolling-up mechanism 300 and two dust collection mechanisms 500, wherein a dust collection mechanism 500 is set to the top of cutting mechanism 200, another dust collection mechanism 500 is set to cutting mechanism 200 Lower section.

Refering to Figure 1, unreeling structure 100 is including material volume 110 and crosses roller 140；Barrier film base material 700 is wound in material volume On 110, material volume 110 carries out blowing by the driving (not shown) of material volume driving device in the method for rotation；The barrier film base material of releasing 700 lead into cutting mechanism 200 via roller 140 is crossed.

In order to preferably export barrier film base material 700, unreeling structure 100 further includes to provide 700 tape transport of barrier film base material The pendulum roller 130 and jockey pulley 150 of power, and close to cutting mechanism 200, to improve the nip rolls that cutting mechanism 200 cuts quality 160.Pile warp pendulum roller 130 and jockey pulley 150 during 700 tape transport of barrier film base material, pendulum roller 130, which is swung, provides tension, jockey pulley 150 It is equipped with tension sensor, the tension of the barrier film base material 700 of pile warp jockey pulley 150 is able to detect, finally feeds back information to pendulum Roller 130 is exported the stability of reasonable 700 tape transport of tension-proof barrier film base material by pendulum roller 130.Nip rolls 160 can be in diaphragm Substrate 700 flattens barrier film base material 700 before entering cutting mechanism 200, so that barrier film base material 700 enters cutting after being unfolded Mechanism 200, to improve the precision of cutting.

Referring to the diaphragm strip 710 that shown in Fig. 1, barrier film base material 700 is formed after cutting via cutting mechanism 200 and give up Side 720 enters rolling-up mechanism 300.Rolling-up mechanism 300 includes upper winding component 310, lower winding component 320 and receipts edge grinding component 330。

Upper winding component 310 includes upper branch roller 311, upper guide reel 312 and upper Scroll 313.Lower winding component 320 wraps Include lower branch roller 321, lower guide reel 322 and lower Scroll 323.Upper branch roller 311 and lower branch roller 321 are respectively used to carrier Diaphragm strip 710 after point cutting, and by guidance to corresponding upper guide reel 312 and lower guide reel 322.Upper 312 He of guide reel Lower guide reel 322 is drive roll, and roll surface is coated with soft material, and, friction big to the cornerite of diaphragm strip 710 greatly, can prevent diaphragm 710 sideslip of item facilitates guidance diaphragm strip 710 to enter upper Scroll 313 and lower Scroll 323, is rolled into required diaphragm material volume.On Scroll 313 and lower Scroll 323 are set as driving shaft, convenient for winding diaphragm strip 710.

It receives edge grinding component 330 and crosses roller 331 and receipts edge grinding axis 332, in the slitting process, barrier film base material 700 including several Size can not just be divided into it is several needed for width diaphragm strip 710, always have an edge grinding 720 of inadequate width, edge grinding 720 by Several to cross the guidance of roller 331 to receipts edge grinding axis 332, edge grinding axis 332 is driving shaft, can wind edge grinding 720.

Shown in please see Fig. 2 to Fig. 4, cutting mechanism 200 includes upper knife assembly 210, lower knife assembly 220, cutter driving dress 230, knife rest 240 and cutting die bottom deck assembly 250 are set, cutter actuating device 230 is set as decelerating motor.

Upper knife assembly 210 includes upper cutter shaft 211 and the upper cutter 212 being set on cutter shaft 211, and upper cutter 212 uses Dise knife.212 side of upper cutter is equipped with upper cutter head 213, and elastic component 214 is arranged between upper cutter head 213 and upper cutter 212, elasticity Part 214 is spring, and after upper cutter 212 folds knife with lower cutter 222, elastic component 214 can be in axial (i.e. right and left in Fig. 3 To) on squeeze upper cutter 212, to upper cutter 212 1 power towards lower cutter 222, so that upper cutter 212 touch incision always Knife 222 realizes cutting for barrier film base material 700.According to needs are cut, axially spaced be provided in multiple groups is cut on upper cutter shaft 211 Knife 212, is equipped with fixes sleeve 216 between each group upper cutter 212, and fixes sleeve 216 can limit the position of upper cutter 212 and solid Determine the spacing between each group upper cutter 212, it is ensured that the precision that barrier film base material 700 is cut.

Lower knife assembly 220 is also adopted including lower 221 and the lower cutter 222 being set in lower 221, lower cutter 222 Use dise knife.Also axially spaced-apart is provided with multiple groups lower cutter 222 in lower 221, corresponding with upper knife assembly 210, each group incision Fixes sleeve 226 also is provided between knife 222.Lower cutter 222 be it is step-like, reserved between fixes sleeve 226 for upper cutter 212 The recess (not indicating) of incision, when cutting barrier film base material 700, upper cutter 212 enters recess, and elastic component 214 pushes upper cutter 212 Against lower cutter 222.Specifically, the knife of lower cutter 222 faces away from 212 direction of upper cutter and is arranged diagonally downward, under making The wedge angle that the apex angle of cutter 222 is constituted convenient for cutting, in addition, being close to lower cutter by elastic component 214 when upper cutter 212 is cut 222 knife faces are conducive to preferably cut barrier film base material 700.

Knife rest 240 is movably arranged on cutting die bottom deck assembly 259, and knife rest 240 is equipped with reinforcing rib 243, reinforcing rib 243 are located at the two sides of lower cutter 222 on 240 width direction of knife rest (i.e. front-rear direction in Fig. 4), and are higher than lower cutter 222 bottom surface is realized and protects lower knife assembly 220.

Cutter actuating device 230 drives upper knife assembly 210 and lower knife assembly 220 to rotate together by synchronous belt 232, to every Film base material 700 is cut, and specifically, lower 221 is driving shaft, and the one end not being connected with cutter actuating device 230 is set There is driving wheel 234, corresponding, upper 211 one end of cutter shaft is equipped with the driven wheel 236 for being located at 234 top of driving wheel, driving wheel 235 It is linked by synchronous belt 232 and driven wheel 236, the both ends of upper cutter shaft 211 and lower 221 are rotatably arranged on knife rest 240.

Incorporated by reference to shown in Fig. 5, cutting die bottom deck assembly 250 includes the bottom plate for support knife rest 240 being connected with substrate 1 251, substrate 1 is the big plate of each mechanism installation of diaphragm cutting machine, the position that bottom plate 251 is connected with substrate 1 i.e. cutting mechanism 200 Corresponding cutting station.After knife rest 240 and bottom plate 251 assemble in place, the cutting die of upper knife assembly 210 and lower knife assembly 220 composition Component is just in place.
