[0037] A second limiting rod 6 is welded to the right end of the shift block 2, and a slider 7 slides on the second limiting rod 6, and a cutter 8 is fixed to the front and rear ends of the slider 7. A second spring 9 is nested on the top of the second limiting rod 6, and the top of the second spring 9 is connected to the top of the second limiting rod 6. The top of the slider 7 extends into the interior of the second limiting rod 6, and a protrusion 10 slides on the top of the slider 7, and the top of the protrusion 10 is arranged in an arc shape. The left end of the protrusion 10 is connected to a third spring 11, and the left end of the third spring 11 is connected to the inside of the slider 7.

The slider 7 is pushed on the second limiting rod 6 by the force of the second spring 9, and then the slider 7 drives the cutter 8 to cut the packaging film body 4. By reversing the above operation, the slider 7 will squeeze the second spring 9, so that the second spring 9 is compressed and the position of the slider 7 is fixed by the engagement of the protrusion 10 with the second limiting rod 6.

[0045] refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7, place the package on the shift rod 13, so that the shift rod 13 moves toward the inside of the wrapping machine body 1 under the weight, and the movement of the shift rod 13 will drive the clamping plate 16 to move on the fixed rod 17 through the pull rope 15, and the movement of the clamping plate 16 will squeeze the fifth spring 18, so that the fifth spring 18 is compressed and stressed. The clamping plate 16 can prevent the package from moving during winding, thereby improving the stability of winding.
