Method and device for closing compression roller when strip steel is broken, medium and coiling machine

The invention relates to the technical field of coiled strip steel, and discloses a method and device for closing a compression roller during strip steel breakage, a medium and a coiling machine. The method comprises the following steps: in response to a strip breaking instruction of shutdown of the coiling machine, stopping input power of a mandrel, and controlling a compression roller of the coiling machine to press mandrel strip steel until the speed of the mandrel is reduced to zero. The service life of equipment is prolonged, and the treatment time generated by strip steel breakage during strip steel curling is shortened. 本申请涉及卷曲带钢技术领域，揭示了一种带钢断带时关闭压辊的方法、装置、介质及卷取机。该方法包括：响应于卷取机停机的断带指令，停止芯轴的输入动力，并控制卷取机的压辊压向芯轴带钢直至芯轴速度降为零。本申请提高设备使用寿命，降低卷曲带钢时由于带钢断带产生的处理时间。
