The invention discloses a rolling material expanding and unwinding device, which comprises a rotating mechanism and a rotating disc assembly connected with it. The rotating disc assembly comprises a rotating disc body, which is movably distributed with at least two expanding and tightening blocks on the circumferential surface of the rotating disc body, and a movable block which is connected with the expanding and tightening block by a wedge-shaped structure is connected with a radial direction driving the expanding and tightening block. An elastic member that is tightened internally on a movable block; a linear drive mechanism, connected with a movable block, is used to drive the movable block to move along the axial direction of the turntable body so as to cause the bulging block to move radially outward or inward relative to the turntable body, thereby tightening or loosening the coil; the above device drives the movable block to move in a straight line through a linear drive mechanism. Then it can drive the expansion block which is connected with the movable block through the wedge structure to move outward radially, thereby expanding and tightening the coil on the rotating disc assembly, and turning under the action of the rotating mechanism. The installation and disassembly of the coil is highly automatic, and the higher coaxiality between the coil and the rotating disc assembly is maintained.

一种卷料胀紧放卷装置
本专利技术涉及放卷装置,尤其是一种卷料胀紧放卷装置。
技术介绍
目前,在制作安规电容时,通常利用金属化薄膜进行收卷而形成电容的芯纸。金属化薄膜在收卷之前为卷料,普通的放卷装置由电机带动转动盘旋转,将卷料与转动盘同轴设置,并依靠垫片来增加卷料的中心与转动盘之间的摩擦力以防止两者脱离,或者先将卷料套在转动盘上,然后通过螺帽从卷料的侧面将卷料压紧于转动盘上以防止两者脱离;以上两种结构的放卷装置皆需要较长的准备时间来安装卷料,自动化程度下,严重影响生产效率,并且无法保障卷料与转动盘的同轴度,从而导致金属化薄膜在放卷时的张紧力波动较大,最终影响电容芯纸的质量,从而影响电容的性能。
