High-speed spiral transverse cutting machine

高速螺旋横切机

Abstract

A high-speed spiral transverse cutting machine comprises an upper knife roll, an upper cutter, a lower knife roll, a lower cutter and a driving motor, wherein the upper knife roll is arranged parallel with the lower knife roll; the upper knife roll and the lower knife roll are connected with driving elements through a transmission device respectively; the upper cutter is fixedly connected onto the upper knife roll; the lower cutter is fixedly connected onto the lower knife roll; each of the upper cutter and the lower cutter comprise a cutting edge part respectively; the cutting edge part of the upper cutter is positioned at the maximum diameter of the circumference that the upper cutter encircles the upper knife roll to rotate; the cutting edge part of the lower cutter is positioned at the maximum diameter of the circumference that the lower cutter encircles the lower knife roll to rotate; the rotating diameter of the cutting edge part of the upper cutter is greater than that of the cutting edge part of the lower cutter. According to the high-speed spiral transverse cutting machine, the displacement of transverse cutters in the horizontal direction is basically equal to the horizontal displacement of corrugated boards; when cut, the corrugated boards are not over pressed, the incision is aesthetically pleasing, the shearing force of knife rolls is reduced, the service life of the knife rolls is prolonged and the vibration and noise of the machine are reduced greatly.
一种高速螺旋横切机,包括上刀辊、上切刀、下刀辊、下切刀和驱动电机,上刀辊和下刀辊平行设置,上刀辊和下刀辊各自通过传动装置与驱动元件连接,上切刀固定连接在上刀辊上,下切刀固定连接在下刀辊上,其中,上切刀和下切刀各自包括有一个刀刃部,上切刀的刀刃部位于上切刀绕上刀辊轴的旋转圆周的最大直径处,下切刀的刀刃部位于下切刀绕下刀辊轴的旋转圆周的最大直径处,上切刀的刀刃部的旋转直径大于下切刀的刀刃部的旋转直径。本实用新型可使横切刀水平方向的位移基本等于瓦楞纸板的水平位移,剪切瓦楞纸板时不会造成过多挤压,切口美观,降低刀辊的剪切力,延长了刀辊的寿命,并且机器的振动和噪音也大大减小。
