Description

High-speed screw transverse cutting unit
Technical field:
The utility model relates to mechanical field, relates in particular to cutting machine for corrugated paper board, particularly a kind of high-speed screw transverse cutting unit.
Background technology:
Spiral transverse cutting machine is the nucleus equipment in corrugated paper board production line, and its shear precision has a strong impact on the end product quality of corrugated board.In prior art, for the otch of strict guarantee cardboard vertical with cardboard, need to guarantee that the linear velocity of spiral transverse cutting machine cutting knife and the speed of cardboard are strictly identical, but the existence due to cal(l)iper, at cutting knife, from cutting knife, contact cardboard to cutting off the process of cardboard, if the linear velocity Vt of cutting knife is identical with sewing thread on card speed, the horizontal velocity Vh of cutting knife can be less than the linear velocity of cardboard so, be that the horizontal displacement of rotor and the displacement of cardboard are different, cause cardboard extruding while shearing, reduce upper cutter, the service life of lower cutter and rotor, cause cutting torsion to increase, therefore must select the rotor of powerful motor and high rigidity, increased cost.
Summary of the invention:
The purpose of this utility model is to provide a kind of high-speed screw transverse cutting unit, described this high-speed screw transverse cutting unit to solve the horizontal displacement speed of rotor in prior art and the velocity of displacement of cardboard service life unequal and the cutting torsion increase, cutting knife and the rotor that cause low technical problem.
This high-speed screw transverse cutting unit of the present utility model, comprise rotor, upper cutter, lower rotor, lower cutter and drive motors, upper rotor and lower rotor be arranged in parallel, upper rotor is connected with drive motors by transmission device separately with lower rotor, upper cutter is fixedly connected on rotor, lower cutter is fixedly connected on lower rotor, it is characterized in that: upper cutter and lower cutter include a blade part separately, the blade part of upper cutter is positioned at upper cutter around the maximum gauge place of the rotation round of upper tool roller axis, the blade part of lower cutter is positioned at lower cutter around the maximum gauge place of the rotation round of lower tool roller axis, the rotating diameter of the blade part of upper cutter is greater than the rotating diameter of the blade part of lower cutter.
Further, the rotating diameter of the blade part of upper cutter increases more than 4% than the rotating diameter of the blade part of lower cutter.
Concrete, upper cutter is provided with mounting hole, and lower cutter is provided with mounting hole, and upper cutter and lower cutter are bolted on the spiral base of upper rotor and lower rotor by its mounting hole.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model increases upper cutter rotating diameter in high-speed screw transverse cutting unit, make upper cutter point of a knife horizontal velocity substantially equal the speed of service of cardboard, it is the horizontal displacement that the displacement of revolving knife horizontal direction equals corrugated board substantially, and reduce the rotating diameter of lower cutter simultaneously, can shorten upper lower cutter and contact cardboard to the time of cutting off cardboard simultaneously, thereby make transverse cutting unit when shearing corrugated board, can not cause too much extruding, make otch attractive in appearance, and the shearing force of reduction rotor, extended the life-span of rotor, and vibration and the noise of machine also reduce greatly, and the reducing of the increase of the rotating diameter of upper cutter and the rotating diameter of lower cutter, also avoided the contact for the second time of upper lower cutter, the life-span of the cutting knife of increase.
Accompanying drawing explanation:
Fig. 1 is the structural representation of high-speed screw transverse cutting unit of the present utility model.
Fig. 2 is the utility model course of work schematic diagram.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, high-speed screw transverse cutting unit of the present utility model, comprise rotor 1, upper cutter 3, lower rotor 2, lower cutter 4 and drive motors, upper rotor 1 is connected with drive motors by transmission device separately with lower rotor 2, upper cutter 3 is fixed on the spiral base of rotor 1, lower cutter 4 is fixed on the spiral base of lower rotor 2, wherein, the rotating diameter D1 of upper cutter blade is slightly larger than 3% of its theoretical rotating diameter, and the rotating diameter D2 of lower cutter blade is slightly less than 1% of its theoretical rotating diameter.
Further, upper cutter is provided with mounting hole, and lower cutter is provided with mounting hole, and described upper cutter and lower cutter are bolted on described spiral base by the mounting hole on it.
Upper cutter and lower cutter in corrugated board shear history in Fig. 2, have been provided at relative position in the same time not.
As Fig. 1, w1 is the angular velocity of rotation of upper rotor, w2 is the angular velocity of rotation of lower rotor, Vh is the horizontal component of upper cutter linear velocity Vt, Vv is the vertical component of upper cutter linear velocity Vt, because the thickness of corrugated board 5 is generally in 1.5 ~ 15mm left and right, when upper cutter 3 contact cardboard in the process of cutting off, its horizontal velocity Vh is always in slight change, consider the thickness range of existing upper and lower cutter structure and corrugated board, so that the rotating diameter D1 of its upper cutter 3 is designed to be slightly larger than 3% of theoretical rotating diameter, the linear velocity Vt that is to say upper cutter 3 be slightly larger than cardboard linear velocity 3%, make its horizontal velocity Vh substantially equal the speed of service of cardboard, it is the horizontal displacement that the displacement of revolving knife horizontal direction equals corrugated board substantially, and the rotating diameter D2 of lower cutter 4 is designed to be slightly less than 1% of theoretical rotating diameter, can shorten upper lower cutter and contact cardboard to the time of cutting off cardboard simultaneously, thereby make transverse cutting unit when shearing corrugated board, can not cause too much extruding, make otch attractive in appearance, and the shearing force of reduction rotor, extended the life-span of rotor.And vibration and the noise of machine also reduce greatly.And the reducing of the rotating diameter of the increase of the rotating diameter of upper cutter 3 and lower cutter 4, also avoided the contact for the second time of upper lower cutter, the life-span of the cutting knife of increase.By theory, calculate, the rotating diameter increase 3% of upper cutter 3 and the rotating diameter of lower cutter 4 reduce 1%, be very little, and facts have proved it is also like this for the impact of shearing the squareness of cardboard out.
