After the winding operation is completed, the respective power bodies 51 and the respective chucks 1 are driven to move outward by the power cylinders 50, so that the compression springs 13 return to the normal position, and the wedge-shaped sliders 14 also slide into the wedge-shaped grooves 8 M398535. In order to drive each of the pushing members 23 to slide in and to be disposed in each of the first cutouts 21, the paper tube 4〇 can be detached from the 4 chucks 1' for unloading the paper tube 4〇, and prepared Carry out the next roll job. The above-mentioned coiling operation is applicable to the paper tube 4 with a small diameter, and when the paper tube 6 has a large diameter, the system needs to be used with the second cooling expansion 30; as shown in the eighth figure The second chuck expansion member 30 is sleeved on the first-to-head expansion member 2, so that the inner sides of the sliding members are supported by the respective pushing members 23, and then the two ends of the paper tube 60 are respectively sleeved. And on the second chuck extension 3〇. As shown in the ninth figure, after the paper tube 60 is positioned, the power cylinders 5 on both sides will push the base body 51' respectively to drive the respective chuck bodies 1 () toward the respective ... Decreasing, and causing the first head extension 2◦ to generate a reaction force with the first chuck extension 3〇, so that each pushing member 23 slides toward the surface of each first notch 21 to discharge the surface of the material-wei expansion member 2〇, and The rib members % and the pushing members 35 are reduced. At this time, the spring member 33 is elastically turned away, and each pushing member 35 is slid out of the surface of the second chuck expanding member 30 to support The paper tube 60 is opened for preliminary work as described above. After the winding operation is completed, each of the bases 51 and the respective jaws are driven to move outward by the power cylinders 50. By the elastic returning force of the spring elements 33, the sliding members 34 drive the second notches 32 to make Each of the pushing members 35 slides into the ring recess 3 in the direction of each of the second notches 32. At this time, the paper tube 6 is detached from the chuck 1 and the second chuck extension 30' for unloading. The paper tube 60 is prepared for the next lap. Since the paper tube 60 is attached to the pusher 35 in a surface contact manner to greatly increase the contact area between the two, the paper tube 60 has the same advantage as the contact area described above.
