[0037] Example 1

[0038] Please refer to Figure 1-4 A release film bending roller comprises: a hollow roller body 1, a bending core assembly 6 mounted in the middle of the hollow roller body 1, connecting shafts 2 disposed on either side of the hollow roller body 1, brackets 3 mounted around the circumference of the connecting shafts 2 on both sides, a hand lever adjuster 4 mounted on one of the brackets 3, fixing blocks 5 mounted on both ends of the hollow roller body 1, and connecting assemblies disposed between the connecting shafts 2 and the ends of the bending core assembly 6. The connecting assemblies comprise a displacement assembly and a fixing assembly. The displacement assembly comprises an internally threaded barrel 606 rotatably engaged with the circumference of the bending core assembly 6, two fixing rings 601 mounted around the circumference of the bending core assembly 6, and a rotation groove 602 formed between the two fixing rings 601. A rotating ring 604 is mounted on one end of the internally threaded barrel 606 proximal to the bending core assembly 6, the rotating ring 604 rotatably engaged within the rotation groove 602, and a plurality of first balls 605 rotatably engaged with the inner wall of the rotating ring 604, the plurality of first balls 605 being located within the rotation groove 602. A threaded post 608 is mounted on the end of the connecting shaft 2 near the curved core assembly 6. The outer surface of the threaded post 608 is threadably engaged with the inner wall of the internally threaded barrel 606. A square block 607 is mounted on the end of the threaded post 608 near the curved core assembly 6. A square slot 603 is defined at one end of the curved core assembly 6, and the square block 607 slidably fits within the slot 603.

[0039] Implementation process: By rotating the threaded barrel 606, the rotating ring 604 rotates in the rotating groove 602 of the bent iron core assembly 6, and the friction generated by the threaded barrel 606 during rotation is reduced by the first ball 605 set on the inner wall of the rotating ring 604. The threaded column 608 of the connecting shaft 2 is threadedly fitted in the internal threaded barrel 606, thereby driving the connecting shaft 2 to slide in the square groove 603 through the square block 607, so that the length of the connecting shaft 2 at both ends of the hollow roller body 1 can be adjusted, thereby adjusting the distance between the bracket seats 3 installed on the connecting shafts 2 on both sides.

[0040] Implementation benefits: It is easy to adjust the distance between the bracket seats 3 installed on the connecting shafts 2 on both sides, and the bracket seats 3 on both sides do not need to be disassembled and assembled to be installed on different equipment.

[0041] Example 2

[0042] The fixing assembly includes a rotating cylinder 7 that slides onto the outside of the internally threaded cylinder 606. A plurality of fixing pins 701 are installed on the side of the rotating cylinder 7 near the fixing block 5. A plurality of fixing slots 702 are defined on one side of the fixing block 5. The fixing pins 701 engage with the fixing slots 702. A plurality of anti-slip strips 703 are installed around the circumference of the rotating cylinder 7. A plurality of limiting strips 705 are installed around the inner wall of the rotating cylinder 7. A plurality of limiting slots 704 are defined on the outer circumference of the internally threaded cylinder 606. The limiting strips 705 slide within the limiting slots 704. A positioning block 706 is installed on the inner wall of the rotating cylinder 7. An annular block 708 is provided on the side of the positioning block 706 near the internally threaded cylinder 606. An elastic member 707 is installed between the annular block 708 and the positioning block 706. A plurality of second balls 709 are rotatably engaged with the side of the annular block 708 near the internally threaded cylinder 606.

[0043] Implementation process: The rotating cylinder 7 uses the force of the elastic member 707 to make the annular block 708 and the second ball 709 contact one side of the internal threaded cylinder 606. The fixing pin 701 of the rotating cylinder 7 is located in the fixing groove 702, which limits the rotation of the rotating cylinder 7. The rotating cylinder 7 and the internal threaded cylinder 606 are slidably connected through the limiting groove 704 and the limiting bar 705 to limit and fix the internal threaded cylinder 606. When it is necessary to adjust the length of the extended connecting shaft 2, it is necessary to push the rotating cylinder 7 outward to make the fixing pin 701 away from the fixing groove 702, thereby releasing the limiting fixation of the rotating cylinder 7 and the internal threaded cylinder 606.

[0044] Implementation benefits: The rotating cylinder 7 and the internal thread cylinder 606 can be automatically limited and fixed.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
