[0024] The clamping assembly 11 includes a mounting seat 111, a slide groove 112, a slider 113, a transmission shaft 114, a transmission roller 115, a driving shaft 116, a driving roller 117, a driving mechanism 118 and a threaded rod 119. The top of the support frame 1 is fixedly connected to the mounting seat 111. Two slide grooves 112 are provided on the inner side of the mounting seat 111. The inner sides of the two slide grooves 112 are slidably connected with sliders 113. A transmission shaft 114 is rotatably connected between the two sliders 113. The outer side of the transmission shaft 114 is fixedly connected with a transmission roller 115. The inner side of the mounting seat 111 is rotatably connected with a driving shaft 116 located below the transmission roller 115. An active roller 117 is fixedly connected to the outer side of the driving shaft 116. The container bag 10 is located between the transmission roller 115 and the active roller 117. The container bag 10 is in contact with the transmission roller 115 and the active roller 117 respectively. A driving mechanism 118 for driving the driving shaft 116 to rotate is provided on the outer side of the driving shaft 116.

The outer sides of the driving shaft 116 and the transmission shaft 114 are fixedly connected with transmission gears 1110, and the two transmission gears 1110 are meshed with each other.

[0025] With the above arrangement, firstly, the bolts are tightened to release the connection between the first cylinder push rod 7 and the support bracket 3, the rotating shaft 4 is removed from the support bracket 3, the original rotating drum 5 is removed from the outer side of the rotating shaft 4, and the new rotating drum 5 with the container bag 10 is replaced and re-clamped on the outer side of the rotating shaft 4, and then the rotating shaft 4 is re-installed on the support bracket 3, and the container bag 10 is passed through the first auxiliary roller 8, the two second auxiliary rollers 9, between the right-hand driving roller 115 and the active roller 117, the four second auxiliary rollers 9, between the left-hand driving roller 115 and the active roller 117 and the cutting assembly 12 in sequence, and the threaded rod 119 is rotated to make the slider 113 slide downward along the slide groove 112 until the active roller 117 and the driving roller 115 clamp the container bag 10 (it should be noted that a positioning groove is provided on the slider 113, so that the threaded rod 119 can be placed exactly, so as to avoid the threaded rod 119 from swinging when moving downward, making it difficult to make the active roller 117 and the driving roller 115 clamped). The container bag 10 is clamped), the driving mechanism 118 is started, the driving shaft 116 is rotated, and the transmission shaft 114 is driven to rotate under the transmission action of the transmission gear 1110, thereby the active roller 117 and the transmission roller 115 are rotated, and the active roller 117 and the transmission roller 115 rotate in the opposite direction. Under the action of friction, the container bag 10 between the active roller 117 and the transmission roller 115 is transferred to the left, and finally the cutting work of the container bag 10 is completed by the cutting component 12. It should be noted that as the container bag 10 gradually moves to the left, the container bag 10 outside the rotating drum 5 will gradually become thinner, which may cause the container bag 10 to not be in close contact with the first auxiliary roller 8 and the second auxiliary roller 9, which may cause the container bag 10 to be wrinkled. Therefore, it is necessary to start the first cylinder 6 at this time to slowly retract the first cylinder push rod 7 to ensure that the container bag 10 is always in close contact with the first auxiliary roller 8 and the second auxiliary roller 9.
