SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a gear fine-tuning of die-cutting rotor that adjustment is convenient, quick, reliable.

The utility model discloses a realize like this: the utility model provides a gear fine-tuning of die-cutting rotor, includes conveying gear, adjustment cover, rotor, locking screw, jackscrew, dish spring axle pin and belleville spring, conveying gear and adjustment cover are established on the rotor, adjustment cover and conveying gear fixed connection, the adjustment cover side is equipped with the through-hole, locking screw passes the through-hole is fixed rotor and adjustment cover locking, the fixed cylindric lock that is equipped with of axle head of rotor, be equipped with the regulation hole on the adjustment cover terminal surface, the cylindric lock sets up in the regulation hole, belleville axle pin and jackscrew setting are sheathe in the locating sleeve, distribute in two pairs sides of fixed pin to support tight fixed pin, the belleville spring cover is established on dish spring axle pin.

Wherein, the transmission gear and the adjusting sleeve are fixedly connected through a screw.

And the locking screw is also sleeved with a locking gasket.

The utility model has the advantages that: the gear fine-adjustment mechanism of the die-cutting knife roller adjusts the relative position between the die-cutting position and the product by changing the circumferential position of the die-cutting knife roller, namely, the position of the transmission gear is fixed, the position of the die-cutting product is fixed, and the position of the die-cutting knife is changed by rotating. When the angle of the knife roll needs to be adjusted, the locking screw is firstly loosened to enable the adjusting sleeve and the knife roll to be finely adjusted, then the jackscrew is screwed, and the jackscrew can apply a force to the cylindrical pin to enable the knife roll to rotate in the opposite direction for a certain angle; or the jackscrew is loosened, and the shape of the butterfly spring is restored to apply a force to the cylindrical pin, so that the cutter roller rotates in the positive direction by a certain angle; after the position is adjusted, the locking screw is screwed again, so that the knife roll and the adjusting sleeve are completely fixed, the gear fine adjustment mechanism is simple to adjust, convenient and quick to operate, the stress distribution of the disc spring is uniformly and progressively reduced from inside to outside, the effect of low stroke and high compensation force can be realized, and the use stability and the die cutting precision are effectively improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As an embodiment of the gear fine-adjustment mechanism of the die-cutting knife roll of the utility model, as shown in figures 1 to 3, the gear fine-adjustment mechanism comprises a transmission gear 1, an adjusting sleeve 2, a knife roll 3, a locking screw 4, a jackscrew 5, a disc spring shaft pin 6 and a disc spring 7, the transmission gear 1 and the adjusting sleeve 2 are sleeved on the knife roll 3, the adjusting sleeve 2 is fixedly connected with the transmission gear 1, a through hole 21 is arranged on the side surface of the adjusting sleeve 2, the locking screw 4 passes through the through hole 21 to lock and fix the knife roller 3 and the adjusting sleeve 2, a cylindrical pin 8 is fixedly arranged at the shaft end of the knife roller 3, an adjusting hole 22 is arranged on the end surface of the adjusting sleeve 2, the cylindrical pin 8 is arranged in the adjusting hole 22, the disc-shaped shaft pin 6 and the jackscrew 5 are arranged on the positioning sleeve 2, distributed on two opposite sides of the fixing pin 8 and tightly abutted against the fixing pin 8, and the disc-shaped spring 7 is sleeved on the disc-shaped shaft pin 6.

The gear fine-tuning mechanism of the die-cutting knife roller adjusts the relative position between the die-cutting position and the product by changing the circumferential position of the die-cutting knife roller, namely, the position of the transmission gear 1 is fixed, the position of the die-cutting product is fixed, and the die-cutting knife rotates to change the position. When the angle of the knife roll 3 needs to be adjusted, the locking screw 4 is firstly unscrewed, so that the adjusting sleeve 2 and the knife roll 3 can be finely adjusted, then the jackscrew 5 is screwed, and at the moment, the jackscrew 5 can apply a force to the cylindrical pin 8, so that the knife roll 3 rotates in the opposite direction for a certain angle; or the jackscrew 5 is loosened, and the butterfly spring 7 can apply a force to the cylindrical pin 8 when the shape is recovered, so that the knife roller 3 rotates in the positive direction for a certain angle; after the position is adjusted, the locking screw 4 is screwed again, so that the knife roll 3 and the adjusting sleeve 2 are completely fixed, the gear fine adjustment mechanism is simple to adjust, convenient to operate and quick, the stress distribution of the disc spring 7 is uniformly decreased from inside to outside, the effect of low-stroke high compensation force can be realized, and the use stability and the die cutting precision are effectively improved.
