[0019] The following is combined with Figure 1 - Figure 4 This application is described in further detail.
[0020] Reference Figure 1 - Figure 4A winding device for paper printed materials comprises a winding roller 1 and a mounting seat 2 for mounting the winding roller 1, a bidirectional lead screw 3 is provided for rotation inside the winding roller 1, both ends of the bidirectional lead screw 3 are threadedly connected with an adjusting seat 4, and the adjusting seat 4 also slides axially in the winding roller 1, a follower lead screw 5 which is equidistantly distributed on the outside of the bidirectional lead screw 3 is provided for rotation inside the winding roller 1, the outer end of the follower lead screw 5 is threadedly connected with a driving plate 6 which moves axially along the winding roller 1, a positioning block 7 which is connected to the driving plate 6 and can be radially retracted is provided inside the adjusting seat 4, which can be flexibly adjusted according to the length of the roll, and has the advantage of high adaptability.
[0021] Reference Figure 3 - Figure 4 A driving gear 9 is fixed on the bidirectional lead screw 3, and a driven gear 10 meshing with the driving gear 9 is fixed on the follower lead screw 5. An adapter seat 11 is provided at one end of the follower lead screw 5 close to the inner side of the winding roller 1, and a No. 1 spring 12 is provided between the adapter seat 11 and the winding roller 1. The follower lead screw 5 is rotatably mounted on the adapter seat 11, and the driven gear 10 can also slide axially on the driving gear 9. Through this cooperation, the adjustment seat 4 and the driving plate 6 can move synchronously and form a spacing difference at the same time. The synchronous movement realizes position adjustment, and the formed spacing difference is used to drive the positioning block 7, which has the advantages of good linkage and flexibility.
[0022] Reference Figure 4 A twisting wheel 8 is fixed at one end of the bidirectional lead screw 3, and an adapter frame 13 is installed at a position of the follower lead screw 5 near the outer end of the winding roller 1. The twisting wheel 8 is located in the adapter frame 13. The adapter frame 13 is provided to form a space for operating the twisting wheel 8 without affecting the adjustment and docking work.
[0023] Reference Figure 4 A No. 2 spring 14 is provided between the driving plate 6 and the adjusting seat 4, and a hinged connecting rod 15 is provided between the driving plate 6 and the positioning block 7. After the driving plate 6 is pushed toward the adjusting seat 4, the positioning block 7 is driven to move radially through the connecting rod 15. The adjusting seat 4 and the driving plate 6 can adjust the position at any time through this cooperation, and can also fix the reel mounted on the outside of the winding roller 1 through the positioning block 7 at any position after adjustment, which has strong flexibility.
[0024] Reference Figure 3 - Figure 4 A guide slider 16 is formed on the adjustment seat 4, and a guide groove 17 for the guide slider 16 to slide is opened on the winding roller 1. The positioning block 7 passes through and slides in the guide slider 16. The guide slider 16 and the guide groove 17 play a guiding role for the adjustment seat 4, and are also used for the transfer of the positioning block 7 inside and outside the winding roller 1.
[0025] Reference Figure 1 - Figure 2A docking cylinder 18 is fixed at one end of the mounting seat 2, and a docking seat 19 is fixed at the adapter frame 13 and the end of the bidirectional lead screw 3 away from the adapter frame 13. A docking block 20 is rotatably provided on the end of the mounting seat 2 away from the docking cylinder 18 and the output end of the docking cylinder 18. The docking block 20 and the docking seat 19 are polygonal structures and are plugged into each other. The docking seat 19 and the docking block 20 are set in two groups, one group is directly connected for manual docking, and the other group is docked through the docking cylinder 18, which has the advantages of convenient docking and high reliability. The docking block 20 directly installed on the mounting seat 2 can be directly connected to the winding drive member to drive the winding roller 1 to perform winding work.
[0026] Working principle: When the winding roller 1 is not installed, the second spring 14 and the first spring 12 are in the reset state. At this time, the positioning block 7 is located inside the adjustment seat 4, and the winding drum can be directly sleeved on the outside of the winding roller 1;
[0027] The position between the two adjustment seats 4 is adjusted according to the length of the reel, and the bidirectional lead screw 3 is rotated by the screw wheel 8. The bidirectional lead screw 3 drives the adjustment seats 4 at both ends to move in opposite directions through the spiral in the middle of the adjustment seat 4. The bidirectional lead screw 3 drives the driving gear 9 to rotate while the driving gear 9 is engaged with the driven gear 10 to drive the follower screw 5 to rotate. The driving plate 6 moves synchronously with the spiral of the follower screw 5 and the adjustment seat 4, and then the docking seat 19 at one end of the principle docking cylinder 18 is docked with the docking block 20 on the mounting seat 2, and the docking at the other end is docked. The connecting block 20 is pushed by the connecting cylinder 18 to connect with the connecting seat 19. After the connection is completed, the connecting cylinder 18 continues to push. At this time, the follower screw 5, the driving plate 6, the driven gear 10, and the adapter seat 11 move axially toward the inside of the winding roller 1. The connecting block 20 also slides on the driving gear 9. After the driving plate 6 moves, the positioning block 7 is pressed out from the inside of the adjustment seat 4 through the connecting rod 15. At this time, the positioning blocks 7 at both ends are located at both ends of the reel, limiting the axial movement of the reel, and the fixing of the reel and the installation of the winding roller 1 can be completed at the same time.
[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
