[0021] The following is combined with Figure 1 - Figure 6 This application is described in further detail.

[0022] Reference Figure 1 - Figure 2 A BOPP tape winding mechanism comprises a winding roller 1 and a mounting frame 2, a transmission disc 4 which can be coaxially fixed with the winding roller 1 is arranged on the mounting frame 2, a fixing seat 3 is arranged between the winding roller 1 and the mounting frame 2, a locking mechanism 5 is arranged in the middle of the winding roller 1, and two symmetrical groups of limiting mechanisms 6 are also arranged inside the winding roller 1.

[0023] Reference Figure 3 and Figure 5 A groove for the movement of the first linkage rod 54 is provided inside the winding roller 1, and a driving groove 55 is provided on the first linkage rod 54. The locking mechanism 5 can realize the synchronous limiting and synchronous separation of multiple round paper rings, thereby ensuring the winding stability and the convenience of unloading.

[0024] Reference Figure 3 and Figure 5 The first linkage rod 54 is arranged along the axial direction of the winding roller 1, the radial movable groove 51 and the locking plate 52 are arranged along the radial direction of the winding roller 1, the driving rod 53 moves in the driving groove 55, and the locking plate 52 slides inside the winding roller 1 through the first linkage rod 54 and moves radially in the winding roller 1 through the cooperation of the driving rod 53 and the driving groove 55. The radial synchronous movement is driven by the axial drive, which has the advantages of good linkage effect and convenient and unified operation.

[0025] Reference Figure 3 and Figure 5 The locking plate 52 is provided with an active notch for the first linkage rod 54, and the driving groove 55 is inclined. The radial spacing between the two end points of the inclination is the active distance of the locking plate 52. The locking plate 52 can be completely retracted into the radial active groove 51 within the active distance, thereby ensuring the flexible movement of the round paper ring on the winding roller 1.

[0026] Reference Figure 4 - Figure 6 The limiting mechanism 6 includes a rotating rod 61 rotatably arranged inside the winding roller 1, a limiting block 62 fixed at one end of the rotating rod 61, and a second linkage rod 63 movably arranged inside the winding roller 1 and hinged to the other end of the rotating rod 61. The limiting mechanism 6 also includes a second threaded hole 64 arranged at one end of the winding roller 1 and a bolt 65 spirally arranged in the second threaded hole 64. The limiting mechanism 6 can synchronously limit one side of the multiple round paper rings inserted, play a role of pre-positioning and auxiliary locking, and effectively improve the fixing efficiency and accuracy of the round paper rings on the winding roller 1.

[0027] Reference Figure 4A rotating adapter 66 is provided at the front end of the bolt 65, and a connecting rod 67 is hinged between the adapter 66 and one end of the second linkage rod 63. The connecting rod 67 plays a role of switching and self-adaptation, and can adapt to the position difference formed after the second linkage rod 63 is pulled, while ensuring the connection effect.

[0028] Working principle: When the locking mechanism 5 and the limiting mechanism 6 are both in the reset state, the round paper ring is inserted into the outer end of the winding roller 1, and then the round paper ring is roughly evenly separated to ensure that the multiple round paper rings and the multiple limiting blocks 62 are distributed one by one;

[0029] The bolt 65 is turned, and the bolt 65 moves toward the inside of the winding roller 1 through the spiral with the second threaded hole 64. The bolt 65 pushes the adapter 66 and the connecting rod 67 to move. The other end of the connecting rod 67 drives the second linkage rod 63 to move. The second linkage rod 63 drives all the rotating rods 61 to move until the limit block 62 is turned over and protrudes from the outer surface of the winding roller 1. Then the limit mechanism 6 at the other end is also operated in the same way.

[0030] Hold one end of the reel 1 and lift it upwards, so that the bottom of each round paper ring contacts with each corresponding limit block 62 under the action of gravity, and the round paper ring corresponds to the position of the two matching locking plates 52;

[0031] After the driving screw 57 is rotated, the first linkage rod 54 is driven to move axially inside the winding roller 1 through the screw with the first threaded hole 56, so that the driving rod 53 moves inside the driving groove 55, and the locking plate 52 is driven to move radially inside the radial movable groove 51 under the action of the inclination angle of the driving groove 55. The corresponding two locking plates 52 position the two ends of the round paper ring, and at this time, multiple round paper rings are evenly positioned at equal distances;

[0032] Then, both limit mechanisms 6 are withdrawn from the limit positions, and all limit blocks 62 are retracted into the interior of the winding roller 1. The winding roller 1 is mounted on the mounting frame 2 through the fixing seat 3 to start the winding operation;

[0033] After winding is completed, the reel 1 is removed from the mounting frame 2, the limit mechanism 6 is disengaged from the limit, and all the limit blocks 62 are retracted into the reel 1. At this time, the tape after winding is disengaged from the limit on the reel 1, and the tape can be directly slid axially to disengage from the reel 1.

[0034] 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.
