[0035] Please refer to Figure 1 As shown, the purpose of this embodiment is to provide a drum-type medical packaging bag cutting machine, including a bracket 9 and a cutting machine body 1 provided thereon. A driving mechanism 3 for driving the rotation of the packaging bag roll 2 is also provided on the bracket 9.

[0036] Furthermore, please refer to Figures 2 - 3 As shown, the output end of the driving mechanism 3 is connected to the transmission assembly 4, the transmission assembly 4 is connected to the rotating assembly 5, the packaging bag roll 2 is provided on the rotating assembly 5, the rotating assembly 5 is detachably connected to the positioning portion 7, the positioning portion 7 is fixedly connected to the base 8, the base 8 is provided on the bracket 9, and the sliding sleeve assembly 6 is sleeved on the positioning portion 7 through the base 8;

[0037] The rotating assembly 5 includes a transmission rod 51. One end of the transmission rod 51 is fixedly connected to the transmission assembly 4, and a telescopic rod 52 is slidably connected to the other end. A sliding rod 53 is provided at one end of the telescopic rod 52 located inside the transmission rod 51. The sliding rod 53 slides in a sliding groove 54 formed on the transmission rod 51. A positioning groove 55 is formed on the telescopic rod 52.

[0038] Furthermore, please refer to Figures 2 - 3 As shown, the transmission assembly 4 includes a first support 41. A second support 42 is rotatably connected inside the first support 41. Both the first support 41 and the second support 42 are in a U-shaped structure; both the first support 41 and the second support 42 are U-shaped seats and the second support 42 is rotatably connected to the first support 41. The second support 42 is connected to the transmission rod 51, so the transmission rod 51 can be lifted.

[0039] Specifically, please refer to Figures 2 - 4 As shown, the positioning portion 7 includes a sleeve 71 for sleeving the telescopic rod 52. A plurality of limiting components 72 for clamping the telescopic rod 52 are fixedly provided on the sleeve 71.

[0040] Further, please refer to Figure 5 As shown, the limiting component 72 includes a limiting cylinder 721 fixedly connected to the sleeve 71. A first limiting block 722 is slidably connected inside the limiting cylinder 721. A second limiting block 723 and a second spring 724 are fixedly connected to one end of the first limiting block 722 located inside the limiting cylinder 721. The other end of the second limiting block 723 extends outside the limiting cylinder 721. The other end of the second spring 724 is fixedly connected to the inner wall of the limiting cylinder 721.

[0041] Furthermore, please refer to Figures 3 - 4 As shown, the sliding sleeve assembly 6 includes a sliding cylinder 61 slidably connected to the base 8. A limiting cavity 62 for limiting the first limiting block 722 is formed inside the sliding cylinder 61. A first spring 63 is also fixedly provided inside the sliding cylinder 61. One end of the first spring 63 is fixedly connected to the inner wall of the sliding cylinder 61, and the other end is fixedly connected to the base 8; when the sliding cylinder 61 slides, the sliding cylinder 61 will squeeze the first limiting block 722 into the limiting cylinder 721. Furthermore, when the sliding cylinder 61 slides to a position where it disengages from limiting the first limiting block 722, at this time, under the elastic force of the second spring 724, the second limiting block 723 will pop out to limit the positioning groove 55 of the telescopic rod 52. At this time, the telescopic rod 52 can be pulled out and retracted into the transmission rod 51.

[0042] In addition, please refer to Figure 2 and Figure 3 As shown, the positioning groove 55 is adapted to the second limiting block 723, and a distance for the second limiting block 723 to move back and forth is formed between the positioning groove 55 and the second limiting block 723.

[0044] The specific working principle is as follows:

[0045] When it is necessary to replace the packaging bag roll 2, only need to slide the sliding cylinder 61. The sliding of the sliding cylinder 61 will squeeze the first limiting block 722 into the limiting cylinder 721, and then the sliding cylinder 61 slides to a position where it disengages from the limit of the first limiting block 722. At this time, under the elastic force of the second spring 724, the second limiting block 723 will pop out to limit the positioning groove 55 of the telescopic rod 52. At this time, the telescopic rod 52 can be pulled out and retracted into the transmission rod 51; furthermore, since both the first support 41 and the second support 42 are U-shaped seats and the second support 42 is rotatably connected to the first support 41, and the second support 42 is connected to the transmission rod 51, the transmission rod 51 can be lifted, and then the packaging bag roll 2 can be pulled out for replacement; after replacement, a new one is sleeved into the transmission rod 51, and then the transmission rod 51 is lowered. At this time, as described above, continue to slide the sliding cylinder 61 to make it disengage from the limit position of the first limiting block 722. At this time, pull out the telescopic rod 52 and insert it into the sleeve 71 until the positioning groove 55 on the telescopic rod 52 engages with the second limiting block 723, and then release the sliding cylinder 61 to realize the limiting effect on the telescopic rod 52 to complete the replacement; thus effectively solving the problem that it is more cumbersome to replace the packaging bag roll 2 of the existing cutting machine.
