The beneficial effects of the utility model are,
1. original cylindrical running roller is changed into eccentric cam-like, can effectively utilize eccentric roller in shear historyThe shearing inertia producing, improves shear effect and the trafficability characteristic of sheet material, simultaneously eccentric roller by the effect of self gravitation to steel bandShearing assist.
2. fixing hole is convenient fixes by screw blade, and the sunk screw in adjustment hole can be to cutter fixing on eccentric rollerShear gap between sheet cutting edge and roller surface is finely tuned.
3. the surface of guide plate, lower than the peak of running roller, makes steel band in shear history, avoid contacting with guide plate, subtractsThe friction of little steel band.
4. the number of teeth of the meshing gear that eccentric roller and running roller homonymy are installed is set to unequal, makes the blade on eccentric rollerEach position of shearing on running roller is not identical, ensures the service life of running roller, has improved the shear effect of sheet material.
5. blade is fixed by screw, facilitates replacing and the installation of blade, and the draw-in groove that breach surface is offered simultaneously can be avoidedBlade is in shear history medium dip, and blade plays corrects and firm effect.
6. the utility model is simple in structure, and build is less, conveniently installs and moves, and facilitates dismounting and the peace of blade simultaneouslyDress.

Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 the are shown novel slitting mill of one that the utility model provides, comprises being up and down and arrangesEccentric roller 3 and running roller 4, eccentric roller 3 and running roller 4 are arranged on installing rack 2, and installing rack 2 is arranged on base 1, and eccentricRoller 3 and running roller 4 rotate setting in opposite directions; On described eccentric roller 3, offer breach 31, and breach 31 places are installed with blade 12,By relatively rotating of eccentric roller 3 and running roller 4, can move forward by guiding sheet metal, simultaneously when blade 12 and roller on eccentric roller 3Wheel 4 is while turning to the position of shearing, and blade 12 is directly cut off steel band, and this device is that more than 10mm sheet material enters for thicknessRow is sheared.
Preferably, the homonymy of described eccentric roller 3 and running roller 4 is provided with pitch wheel 6, and the tooth of two gears 6Number is unequal, makes the each position of shearing on running roller 4 of blade on eccentric roller 3 12 not identical, and through 40～50 times cutCut rear just with it the clipped position on front roller wheel 4 overlap, ensure the service life of running roller 4, improved the shear effect of sheet material.The simultaneously rotating shaft of one of them gear 6 is connected with gearbox 8 by shaft coupling 7, and gearbox 8 by shaft coupling 7 with driveThe main shaft of moving motor 9 connects, and first the rotation of drive motors 9 is slowed down, thereby realize eccentric roller 3 and roller by gearbox 8Relatively rotating of wheel 4.
Preferably, described eccentric roller 3 longitudinal sections are cam-like, make eccentric roller 3 in the time rotating, and utilize eccentric roller 3 rotatingThe shearing inertia producing in process, improves shear effect and the trafficability characteristic of sheet material; And breach 31 is perpendicular type, make blade 12 in peaceWhen dress, the surface of blade 12 is directly fitted on the surface of breach 31.
Preferably, described breach 31 is opened on the dome of eccentric roller 3, and breach 31 surfaces on eccentric roller 3 offer edgeThe draw-in groove 32 axially running through, is stuck in a side of blade 12 in draw-in groove 32 by draw-in groove 32, avoids blade 12 in long-term shearingProcess medium dip, blade 12 plays corrects and firm effect, facilitates blade 12 to be arranged on accurately breach 31 places simultaneously.
Preferably, the blade 12 cutting edge correspondences on described eccentric roller 3, on the center line of roll body 4, are rotating eccentric roller 3Effect because of self gravitation in process is assisted the shearing of steel band.
