Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, fig. 2, fig. 3, and fig. 4, the utility model relates to a film slitting strip cutter mechanism, it includes knife rest 11, install perpendicularly at knife shaft 15 of knife rest 11, through bearing 16 rotatable install in circle cutting blade 18 of knife shaft 15, install in the annular separation blade 19 of circle cutting blade 18 both sides, annular separation blade 19 forms the annular and centre gripping around the elasticity O type circle 20 of establishing in the cutting edge both sides of circle cutting blade 18. Thereby at the both sides face installation annular separation blade of circle cutting blade annular separation blade forms the annular between annular separation blade and the cutting edge of circle cutting blade, again around establishing the better O type circle of elasticity, annular separation blade and elasticity O type circle carry out the centre gripping to circle cutting blade and right steady, the intensity that increases circle cutting blade obtains increasing, and elasticity O type circle still extrudees the film by the cutting, prevent to produce vibrations or skew between cutting edge and the film and pull, make the cutting action more steady, the cutting is more accurate reliable, further protect circle cutting blade, thereby can prolong cutter life-span and guarantee the cutting effect.

Wherein, a flat gasket 21 is arranged between the bearing 16 and the tool rest 11, which improves the installation precision of the bearing and improves the rotating operation precision and stability of the circular cutting blade 18.

In addition, a flat washer 22 is arranged between a suspension end nut of the cutter shaft 15 and the bearing 16, so that the installation accuracy and the operation stability of the bearing and the circular cutting blade 18 are further improved.

Specifically, the tool holder 11 includes a tool holder 13 having an axially disposed tail slot 31, a tool bar 12 mounted on a front section of the tool holder 13, an adjusting screw 32 located in the tail slot 31 and connected to a rear end of the tool bar 12, an adjusting knob 33 sleeved on the adjusting screw 32 and in threaded connection with an inner wall of the tail slot, a compression spring 36 located in the tail slot 31 and sleeved on the adjusting screw 32 and abutting against a front end of the adjusting knob 33, and a hand-twist ring 38 in threaded connection with the adjusting screw 32 to limit a forward movement position thereof.
