目前国内大多数瓦楞纸板生产仍然沿用着机械式的无级变速箱及瞬时机构传动的横切机。这种设备生产率低、剪损大，直接影响企业的经济效益。由于电控技术不过关，机械制造能力有限，刚刚建立起来的瓦楞纸板生产线制造工业，只能继续制造这种过了时的设备，使我国的瓦楞纸板专业 At present, most domestic corrugated board production still follows the mechanical stepless gearbox and instantaneous mechanism drive crosscutting machine. This equipment low productivity, shearing loss, a direct impact on the economic efficiency of enterprises. Due to the electronic control technology, however, the mechanical manufacturing capacity is limited, the newly established corrugated board production line manufacturing industry, can only continue to manufacture such an outdated equipment, so that China’s corrugated board professional
