[0032] Please refer to Figure 1 and Figure 2 A unwinding mechanism of a cutting device, comprising a mounting shaft 1, two connecting parts 2, two limiting parts 3 and a mounting bracket 4.

[0033] The mounting shaft 1 is used for the reel to be sleeved, more specifically, the inner diameter of the reel is greater than the diameter of the mounting shaft 1, so that after the reel is sleeved on the mounting shaft 1, the inner wall of the reel is supported by contacting the mounting shaft 1 downward; the length of the mounting shaft 1 is greater than the length of the reel, so that after the reel is sleeved on the mounting shaft 1, both ends of the mounting shaft 1 can exceed the reel.

[0034] Two connecting parts 2 are fixedly connected to the two end positions of the mounting shaft 1. That is, after the winding drum is sleeved on the mounting shaft 1, the winding drum is between the two connecting parts 2. The connecting part 2 has an annular groove, more specifically, the connecting part 2 is in a cylindrical shape, is sleeved on the mounting shaft 1, and can be fixedly connected to the mounting shaft 1 by using a first bolt 2a. The two end positions of the connecting part 2 are stop rings with a larger outer diameter, and the annular groove is formed in the middle position.

[0035] Two limiting parts 3 are fixedly connected to the mounting shaft 1 and can be axially adjusted and fixed on the mounting shaft 1. More specifically, the limiting part 3 is in a cylindrical shape, and the outer wall has a threaded hole that is communicated to the inside of the cylinder. A second bolt 3a is screwed in the threaded hole. When the second bolt 3a is loosened, the limiting part 3 can move axially relative to the mounting shaft 1. When the second bolt 3a is tightened, the limiting part 3 is fixedly connected to the mounting shaft 1.

[0036] The two limiting parts 3 are kept between the two connecting parts 2. That is, after the winding drum is sleeved on the mounting shaft 1, the winding drum is also between the two limiting parts 3 and is limited in the axial movement by the two limiting parts 3. More specifically, the process of sleeving the winding drum on the mounting shaft 1 is as follows: the connecting part 2 and the limiting part 3 at the same end are detached from the mounting shaft 1; the winding drum is sleeved on the mounting shaft 1 from this end; the limiting part 3 is reinstalled on the mounting shaft 1; and the connecting part 2 is reinstalled on the mounting shaft 1.

[0037] Please refer to Figure 3 In some embodiments, the limiting part 3 includes a plurality of sector annular limiting blocks 3-1, a sleeve ring 3-2, and at least one third bolt 3-3. The sleeve ring 3-2 can be passed through the connecting part 2 and is used to keep the plurality of limiting blocks 3-1 close together. The third bolt 3-3 connects one of the limiting blocks 3-1 and the sleeve ring 3-2. Correspondingly, the fixed connection between the limiting part 3 and the mounting shaft 1 can be realized by the third bolt 3-3 instead of the second bolt 3a described above.

[0038] When the third bolt 3-3 is unscrewed, the sleeve ring 3-2 and the plurality of limiting blocks 3-1 are separated, the plurality of limiting blocks 3-1 can be separated and detached from the mounting shaft 1, the sleeve ring 3-2 is removed from the mounting shaft 1, and the limiting part 3 is detached from the mounting shaft 1. Correspondingly, the sleeve ring 3-2 is sleeved on the mounting shaft 1, the plurality of limiting blocks 3-1 are attached to the mounting shaft 1 and are close together, the sleeve ring 3-2 is sleeved on the plurality of limiting blocks 3-1, and the third bolt 3-3 is screwed in.

[0039] The process of sleeving the winding drum on the mounting shaft 1 can also be as follows: the limiting part 3 at one end is detached from the mounting shaft 1; the winding drum is sleeved on the mounting shaft 1 from this end; and the connecting part 2 is reinstalled on the mounting shaft 1.

[0040] The mounting frame 4 has two mounting notches 4a1 of the same height, and the two mounting notches 4a1 are respectively provided for the annular grooves of the two connecting parts 2.

The retaining rings on the outer sides of the two connecting parts 2 can be respectively attached to the two mounting plates 4a, or the retaining rings on the inner sides of the two connecting parts 2 can be respectively attached to the two mounting plates 4a, and the mounting shaft 1 is limited in the axial movement.

[0041] Referring to Figure 4 In some embodiments, the mounting frame 4 is further horizontally and slidingly connected with two limiting guide wheels 5 at each mounting notch 4a1. An elastic member 6 is arranged between the limiting guide wheel 5 and the mounting frame 4, and the elastic member 6 is used to make the limiting guide wheel 5 close to the mounting notch 4a1. More specifically, the mounting plate 4a has a first protrusion 4b at the position on each side of the mounting notch 4a1; the limiting guide wheel 5 is rotationally connected with a guide wheel frame, the guide wheel frame is fixedly connected with a group of first guide rods through fourth bolts; the first guide rod is horizontally and slidingly connected with the first protrusion 4b; and the elastic member 6 is a compression spring, which is sleeved on the first guide rod to make the limiting guide wheel 5 close to the mounting notch 4a1 until the nut of the fourth bolt abuts against the first protrusion 4b.

[0042] After the mounting shaft 1 is placed in the mounting frame 4, the two limiting guide wheels 5 abut against the outer wall of the upper part of the mounting shaft 1 to avoid the mounting shaft 1 from jumping upward during the rotation of the winding drum.

[0043] Referring to Figure 5 In some embodiments, the limiting part 3 is in the shape of a circular truncated cone. The mounting frame 4 is further provided with a support guide wheel 7 and an adjusting mechanism 8 adjusting the support guide wheel 7 at each mounting notch 4a1. The adjusting mechanism is used to switch the support guide wheel 7 between the inner bottom wall of the mounting notch 4a1 and the position beyond the inner bottom wall of the mounting notch 4a1.

[0044] When the inner diameter of the winding drum is not much larger than the diameter of the mounting shaft 1, the mounting shaft 1 is supported by the inner bottom wall of the mounting notch 4a1, and the winding is performed by the rotation of the winding drum relative to the mounting shaft 1. When the inner diameter of the winding drum is much larger than the diameter of the mounting shaft 1, the fixed connection position of the two limiting parts 3 on the mounting shaft 1 can be adjusted so that the two limiting parts 3 are respectively inserted into the two ends of the winding drum, and the support guide wheel 7 is adjusted, so that the mounting shaft 1 is supported by the support guide wheel 7, and the winding is performed by the rotation of the mounting shaft 1 relative to the mounting frame 4.

More specifically, the first bolt 2a is arranged in reference to the second bolt 3a. When the first bolt 2a is loosened, the connecting portion 2 can be axially moved relative to the mounting shaft 1. When the first bolt 2a is tightened, the connecting portion 2 is fixedly connected to the mounting shaft 1. The distance between the two mounting notches 4a1 can be adjusted. More specifically, the connecting section 4-2 of the mounting frame 4 includes a first section 4-2-1 fixedly connected to the two vertical frame bodies 4-1 respectively, and a second section 4-2-2 telescopically connected to the two first sections 4-2-1.

[0047] According to the length of the winding drum, the two connecting portions 2 and the two mounting notches 4a1 are adjusted so that the connecting portions 2 are relatively close to the end portions of the winding drum, thereby improving the supporting effect and stability.
