Button Catch Brade-point Fault Reason Analysis And Solving Method

After analysis of line fracture of the claw knife, mostly because the instant machine knives back swinging fork with the curved needle plate fracture caused by the collision. For this reason, make sure the swinging fork is properly seated, the simplest approach is to fork triangle swing cam, bent shaft and dial engraved on a plate cam into a consistent, then stop automatically when plug into the knife to adjust foot to ensure knives in 12.5 mm clearance between the drive shaft and the body.

If the knife drive bar and body clearance greater than 12.5 mm, are transferred to the standard location, if in standard position, Rotary loose blade drive shaft nut, take the adjustment 1 mm ~2 mm, locking blades drive shaft nut. Knife not down too far forward, otherwise easily lead to points and cutting edges of exceptions. Finally, in the case of boot, step on the pedal, check the knife back with no collisions.
