At this time, the second support plate (9) on the second roller sleeve pushes the hinged rod (10), and the hinged rod (10) drives the fins (11) of the first support plate (8) to move away from the second shaft sleeve (6) until a plurality of groups of fins (11) abut against the inner wall of the receiving roller sleeve. In the above process, the shifting block (21) moves toward the guide block (20), and the guide block (20) drives the slide plate (18) to squeeze the first elastic member (17), thereby The slide plate (18) drives the positioning block (19) to protrude from the fin (11), and the positioning block (19) is provided with a chamfered portion at one end close to the guide plate (7). When the fin (11) is fully unfolded, the chamfered portion of the positioning block (19) completely protrudes from the fin (11), and the receiving roller sleeve is fixed between the side wall of the fin (11) and the positioning block (19). In the above process, the inclined block (28) pushes the top plate (26) to move toward the end away from the second shaft sleeve (6) until the push plate (23) contacts the guide plate (7); 步骤3、启动电机（12），电机（12）带动主动齿轮（13）转动，主动齿轮（13）带动从动齿轮（14）转动，从动齿轮（14）带动第一轴套（5）转动，进而导向盘（7）带动翅片（11）以及第二轴套（6）转动，进行收卷作业；Step 3, starting the motor (12), the motor (12) drives the driving gear (13) to rotate, the driving gear (13) drives the driven gear (14) to rotate, the driven gear (14) drives the first shaft sleeve (5) to rotate, and then the guide plate (7) drives the fin (11) and the second shaft sleeve (6) to rotate, thereby performing a winding operation; 步骤4、定量收卷的物料卷厚在压板（27）的行程之间，电机（12）停止转动后下料，液压缸（2）输出端伸长带动第二轴套（6）移动，翅片（11）向着第二轴套（6）方向移动，起初推板（23）以及挡板（29）均未接触料卷，随着液压缸（2）的伸长，拨块（21）与导向块（20）错位，第一弹性件（17）推动滑板（18）复位，此时定位块（19）完全收纳入翅片（11）中，随着液压缸（2）的进一步伸长，挡板（29）和推板（23）接触料辊推动料辊移动；Step 4: When the thickness of the quantitatively wound material roll is within the stroke of the pressure plate (27), the motor (12) stops rotating and the material is unloaded.
