本发明的阻挡装置的工作过程:卷料5收卷完成，两个弧形结构12在重力作用下处于打开状态，当卷针4沿卷料5的径向下移，卷针4的外侧壁卡靠在两个施力件31的自由端上，随着卷针4继续沿卷料5的径向下移，施力件31在卷针4的作用下，带动弧形结构12一起绕销轴22转动，进而使得弧形结构12的弧形凹部沿卷料5的周向将卷针4包覆，此时，弧形结构12处于收拢状态，当卷针4沿卷料5的轴向移动时，卷料5的端面抵靠在弧形结构12的第一侧壁121上，阻止卷料5随卷针4的移动而移动，进而使得卷针4从卷料5上脱离，卷针4继续沿卷料5的轴向移动到卷针4的外侧壁与施力部3不卡靠时，弧形结构12在自身重力的作用下绕销轴22反向转动，使得弧形结构12处于打开状态，完成一次卷针4和卷料5的脱离。The working process of the blocking device of the present invention: the rolling material 5 is completed, and the two arc-shaped structures 12 are in an open state under the action of gravity. When the rolling needle 4 moves downward along the radial direction of the rolling material 5, the outer wall of the rolling needle 4 It is stuck on the free ends of the two force-applying members 31. As the rolling needle 4 continues to move downward along the radial direction of the coil material 5, the force-applying member 31 drives the arc-shaped structure 12 to wind around the pin together under the action of the rolling needle 4. The shaft 22 rotates, thereby causing the arc-shaped recess of the arc-shaped structure 12 to cover the rolling needle 4 along the circumferential direction of the rolled material 5. At this time, the arc-shaped structure 12 is in a contracted state, and when the rolling needle 4 moves along the axial direction of the rolled material 5 When moving, the end surface of the roll material 5 abuts the first side wall 121 of the arc-shaped structure 12, preventing the roll material 5 from moving with the movement of the roll needle 4, thereby causing the roll needle 4 to detach from the roll material 5, and the roll needle 4. Continue to move along the axial direction of the coil material 5 until the outer wall of the coil needle 4 and the force-applying part 3 are no longer stuck, the arc-shaped structure 12 rotates reversely around the pin 22 under the action of its own gravity, so that the arc-shaped structure 12 In the open state, the separation of the coil needle 4 and the coil material 5 is completed once.
