[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-6, the utility model provides a technical solution: a material-changing auxiliary fixture structure for a round knife die-cutting machine, which is composed of a fixture main body 1, a tension adjustment bolt 2, a clamping part 3, a fixing part 4 and several fastening bolts 5. Among them, when the fixture main body 1 is in use, it is first sleeved outside the air shaft of the round knife die-cutting machine. In order to fix the fixture main body 1 on the air shaft 6 of the round knife die-cutting machine, an opening 11 is reserved at the top of the fixture main body 1, and through holes 12 and threaded holes 13 are respectively opened on both sides of the opening 11 at the top of the fixture main body 1. After inserting the tension adjustment bolt 2 into the through hole 12 and turning the tension adjustment bolt 2, the tension adjustment bolt 2 is threadedly connected with the threaded hole 13. As the tension adjustment bolt 2 is continuously tightened, the opening 11 gradually shrinks, that is, the inner diameter of the fixture main body 1 shrinks until the fixture main body 1 cannot move on the air shaft of the round knife die-cutting machine;

[0021] In addition, in order to fit the external structure of the air shaft of the round knife die-cutting machine (that is, several clamping protrusions three 61 are arranged outside the air shaft 6), a clamping protrusion one 14 is integrally connected inside the fixture main body 1, and an adjustment groove 15 is reserved inside the fixture main body 1. A clamping part 3 is arranged inside the adjustment groove 15. The clamping part 3 is located on the opposite side of the clamping protrusion one 14, and a clamping protrusion two 31 is connected to the inner side of the clamping part 3. As shown in the attachment Figure 6 As shown, after the fixture main body 1 is sleeved, the grooves between the clamping protrusion one 14 and the clamping protrusion two 31 are both clamped with the clamping protrusion three 61, so that when the fixture main body 1 is not fixed, the fixture main body 1 can move along the air shaft 6. Thus, according to the cutting size of the film roll 7 and in combination with the inherent scale on the air shaft 6 (which is a known prior art and will not be elaborated here), the fixture main body 1 is adjusted to the required position;

[0022] To facilitate the adjustment of the position of the engaging member 3 in the adjustment groove 15, the width of the adjustment groove 15 is greater than the width of the engaging member 3. The fixture body 1 and the engaging member 3 are connected and fixed by a fixing member 4 and four fastening bolts 5. Threaded holes two 16 are reserved on both sides of the adjustment groove 15 on the surface of the fixture body 1. The engaging protrusion two 31 can also be engaged with the air shaft of the round die cutting machine. Threaded holes three 32 are reserved on the surface of the engaging member 3. An adjustment hole 41 is reserved inside the fixing member 4, and through holes two 42 are reserved on both sides of the adjustment hole 41 inside the fixing member 4. When installing the fixing member 4, insert two of the fastening bolts 5 into the through holes two 42, and by turning the fastening bolts 5, make the fastening bolts 5 threadedly connected to the threaded holes two 16, then the fixing member 4 can be installed on the fixture body 1. Then place the engaging member 3 in the adjustment groove 15 and adjust the position of the engaging member 3 inside the adjustment groove 15 (the adjustment standard is that the engaging protrusion two 31 can be engaged in the groove between the engaging protrusions three 61). After adjustment, insert the other two fastening bolts 5 into the adjustment hole 41, and then screw the fastening bolts 5 into the threaded holes three 32 and tighten to complete the fixation of the engaging member 3.
