Detailed description of the invention

For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

Refer to Fig. 1 to Fig. 3,

A kind of rotary film perforating mechanism, comprise frame 100, frame is provided with power source mechanism, power source mechanism is the combination of motor and reductor, and motor 101 is connected with reductor 103 by shaft coupling 102,

Film perforating machine is also with rotary punching mechanism, rotary punching mechanism comprises by the rack-mounted punching rotary core shaft 112 of rolling bearing pedestal first 111, one end of punching rotary core shaft realizes being in transmission connection by chain-drive mechanism first 113 and axle of carrier pulley 121, punching rotary core shaft is also rolled punching rotary sleeve cylinder 114 is installed, punching rotary sleeve cylinder is made up of with the gib block be connected on biside plate the side plate of both sides, is provided with the long guiding hole with rotary core shaft of punching in gib block.

As Fig. 1, shown in Fig. 2, on punching rotary sleeve cylinder, circumference is installed with perforating knife assembly 115, perforating knife assembly comprises perforating knife inner sleeve 1151, perforating knife inner sleeve is arranged in punching rotary core shaft 112 in the mode that key connects, the outside of perforating knife inner sleeve is provided with bevel gear first 1152 in the mode that key connects, the outside of perforating knife inner sleeve is also provided with perforating knife assembly side end cap 1158 by rolling bearing, perforating knife assembly side end cap is bolted on perforating knife outer sleeve 1153, on perforating knife outer sleeve, uniform rolling is provided with punching cutter shaft, 10 punching cutter shafts such as, have been installed in the present embodiment.Bevel gear second 1154 is installed in the inner of punching cutter shaft, bevel gear second engages with bevel gear first, punching cutter shaft is vertical with punching rotary core shaft, the outer end of punching cutter shaft has been threaded perforating knife 1155, the inner of perforating knife nut 1156 that is locked is locked, the outer end of perforating knife has the blade of an annular, and blade has extended internally inner conical surface.

Perforating knife outer sleeve is provided with guider screw, guider screw embeds in long guiding hole, the groove of gib block and perforating knife outer sleeve realizes being slidably matched, so perforating knife assembly can realize axial restraint with punching rotary sleeve cylinder, and when guider screw is loosened, can realize sliding along long guiding hole.

Axle of carrier pulley 121 is provided with input driving section first in the mode that circumference is fixing, export driving section first, export driving section second, input driving section first realizes being in transmission connection by the output of Chain conveyer and power source mechanism, export driving section first to realize being in transmission connection by the input driving section second of Chain conveyer with punching rotary core shaft one end, wherein input driving section first, exporting driving section first is the duplex chain wheel 122 being positioned at frame lateral ends being arranged on axle of carrier pulley, one of them sprocket wheel of duplex chain wheel is connected with the output Chain conveyer of reductor, another sprocket wheel be positioned at the sprocket chain of punching in rotary core shaft and be in transmission connection, export driving section second to realize being in transmission connection with the kind of drive of constant angular velocity and input driving section third, exporting driving section second is gear first 123, input driving section third is gear second 116, gear second is identical with gear first number of teeth modulus and engage each other, gear second is connected with punching rotary sleeve cylinder in the mode that circumference is fixing,

Operating principle of the present utility model is:

Start puncher, motor 101 drives reductor 103 by shaft coupling 102, the output of reductor drives axle of carrier pulley 121 by Chain conveyer, gear first 123 on axle of carrier pulley engages with gear second 116, because gear first is identical with gear second number of teeth modulus, so the transmission of gear first and gear second is reverse by the rotation of the rotary sleeve cylinder 114 that punches and axle of carrier pulley, but velocity magnitude is consistent.The sprocket wheel in punching rotary core shaft 112 is given in power transmission by the duplex chain wheel simultaneously on axle of carrier pulley.Because chain gear transmission does not change transmission direction, so the rotary speed of punching rotary core shaft 112 is contrary with the rotary speed of punching rotary sleeve cylinder.

Because perforating knife outer sleeve 1153 and punching rotary sleeve cylinder are that circumference is fixing, and perforating knife inner sleeve 1151 and punching rotary core shaft 112 are that circumference is fixing, so perforating knife inner sleeve is contrary with the direction of rotation of perforating knife outer sleeve.Be arranged on perforating knife outer sleeve because punching cutter shaft 1157 is perpendicular to punching rotary core shaft, so punching cutter shaft can form rotation and the revolution relative to bevel gear first in bevel gear first 1152, and the angular speed of revolution can be faster because of perforating knife outer sleeve and the relative reverse rotation of perforating knife inner sleeve, so the rotary speed of bevel gear second 1154, punching cutter shaft 1157, perforating knife 1155 can improve further, thus improve the rotary-cut effect of punching.

Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above, but the utility model is not limited to above-mentioned detailed description of the invention, above-mentioned detailed description of the invention is only schematic, be not restrictive, those of ordinary skill in the art is under enlightenment of the present utility model, do not departing under the ambit that the utility model aim and claim protect, a lot of form can also be made, such as: to be 1. connected with reductor by shaft coupling by the motor described in embodiment and to replace with direct-connected reducing motor; 2. the chain-drive mechanism in embodiment is all replaced with Belt Drive mechanism or Synchronous Belt Drives mechanism, even also ensure that bel-drivenn does not throw switch by belt contact roller; 3. be directly arranged on perforating knife inner sleeve by rolling bearing by perforating knife outer sleeve, punching assembly side end cap only plays the effect fixing or hold out against housing washer.These all belong within protection domain of the present utility model.
