Refer to shown in Fig. 2 and Fig. 5, the invention provides a kind of stabilising membrane and cut the film cutting processing method of speed, it is with so that a film when cutting the cutter film 111 of machine (scheming not label) and moving back and forth along a cutting path P with respect to a processing seat 20, can stably bestow suitable film to the base stock 30 on processing seat 20 and cut speed to cut, base stock 30 comprises a plane materiel 31 and a release liners 32, on plane materiel 31, compartment of terrain planning has multiple point of contacts 33 for the treatment of, base stock 30 is accepted cutter film 111 along a throughput direction F conveying with compartment of terrain constantly and is treated the cutting at point of contact 33 on processing seat 20, the film cutting processing method that stabilising membrane of the present invention is cut speed comprises the steps:

One gear unit T is provided, gear unit T in order to according to an initial rotating speed interlock cutter film 111 along cutting path P move back and forth (step S101), therefore rotating speed when gear unit T running can be considered the film that is equivalent to cutter film 111 and cuts speed, or both are close positively related relation;

Provide in order a cutter film motion starting point P1, a cutter film to accelerate starting point P11, a cutter film acceleration summit P2 and cutter film acceleration terminal P12(step S 103 at cutting path P);

Gear unit T is with so that cutter film 111 accelerates starting point P11, cutter film and accelerates the direction that summit P2 and cutter film accelerate terminal P12 and move along move starting point P1, cutter film of cutter film in order, and cutter film 111 accelerates terminal P12 from cutter film again and gets back to cutter film motion starting point P1 to complete again and again move back and forth (the step S105) of cutter film 111 along cutting path P;

In the time that cutter film 111 is positioned at cutter film acceleration starting point P11, start the running of gear unit T to accelerate to a maximum (top) speed and further make the motion of cutter film 111 cut speed motion (step S107) with a suitable film, this suitable film speed of cutting does not limit, need arrange and have different variations depending on each different base stock 30, cut speed but the common preferably film speed of cutting can be equivalent to the film that tool setting film 111 brings in the time that gear unit T runs between 3000RPM to 14000RPM;

Accelerate when the P2 of summit when cutter film 11 is positioned at cutter film, gear unit T running to described suitable film is cut speed, is also that film is cut the maximum (top) speed (step S109) specified to gear unit T institute in process, setting must reach simultaneously; And

In the time that cutter film 111 is positioned at cutter film acceleration terminal P12, gear unit T returns to initial rotating speed (step S111), because now complete to the acceleration of gear unit T, so time cutter film 111 positions be that cutter film accelerates terminal P12, and cutter film 111 to be ready returning back to cutter film motion starting point P1, to cover whole cutting path P, and cyclically the ensuing next one is treated to the cutting that carry out next time at point of contact 33.Refer to Fig. 2, shown in Fig. 4 A and Fig. 4 B, preferably, described gear unit T can at least comprise a final drive shaft 80, one first eccentric drive shaft 50 and with the first eccentric part 52 has the second eccentric drive shaft 60 of the second eccentric part 62, between the first eccentric part 52 and the second eccentric part 62, be connected with axostylus axostyle 70, the convertible rotating speed of final drive shaft 80 ground by master gear 81 to drive, the first gear 51 on transmission the first eccentric drive shaft 50, the first gear 51 is positioned at the non-eccentricity portion (not label) of the first eccentric drive shaft 50, then the first eccentric drive shaft 50 just can rotate, and by axostylus axostyle 70 transmission the second eccentric drive shafts 60, the further drive of the second eccentric drive shaft 60 can interlock the connector 61 of processing seat bottom bar 22 complete the cycle moving back and forth along cutting path P with interlock cutter film 111.

Preferably, accelerate when the P12 of summit when cutter film 111 is positioned at cutter film, cutter film 111 can cut in base stock 30 or cuts in the plane materiel 31 of base stock 30 or cut and treat point of contact 33 in the plane materiel 31 of base stock 30.

Preferably, final drive shaft T can be driven in one first servo motor S1; The second eccentric drive shaft 60 can be driven in one second servo motor S2.

Preferably, described gear unit T also can only comprise a final drive shaft 80 and one first eccentric drive shaft 50, final drive shaft 80 can convert the first gear 51 of rotating speed ground transmission the first eccentric drive shaft 50 moment, and with so that the first eccentric drive shaft 50 interlock cutter films 111 move back and forth along cutting path P.

Again, preferably, the use of the inventive method, also can not comprise the use that maybe need not coordinate the second eccentric drive shaft 60, the first eccentric rod 50 can directly be driven by mode as above via the first servo motor S1, and the first eccentric rod 50 can be directly connected to connector 61 to drive processing seat bottom bar 22(figure slightly), make cutter film 111 can follow film cutting processing method motion as above, this is because the acceleration of cutter film 111 mainly can only be reached via the acceleration of the first servo motor S1.
