[0025] Reference Figure 2 and Figure 3A workbench 10 is fixedly connected to the top of the base plate 1, a groove 11 is opened on the top of the workbench 10, a second cutter 12 is fixedly connected inside the groove 11, a cylinder 13 is fixedly connected to the top of the mounting frame 22, a mounting plate 14 is fixedly connected to the output end of the cylinder 13, a first cutter 15 is fixedly connected to the bottom of the mounting plate 14, mounting blocks 16 are fixedly connected to both sides of the bottom of the mounting plate 14, and a first spring 17 is fixedly connected to the inner top of the mounting block 16.

[0026] The groove 11 is used to install the second cutter 12, and the second cutter 12 cooperates with the first cutter 15 to cut the inner film bag. The cylinder 13 is used to drive the mounting plate 14 to perform cutting and pressing operations. The mounting block 16 is used to install the first spring 17 and the pressing block 18.

[0027] Reference Figure 3 The bottom ends of the first springs 17 are fixedly connected to the tops of the pressure blocks 18, the pressure blocks 18 are slidably connected to the inside of the mounting blocks 16, the bottom sides of the mounting plate 14 are rotatably connected to pressure plates 19, the outer sides of the pressure plates 19 are rotatably connected to smoothing rollers 20, the tops of the pressure plates 19 are fixedly connected to the second springs 21, and the top ends of the second springs 21 are fixedly connected to the bottom of the mounting plate 14.

[0029] Working principle: When the device is used, two groups of motors 3 are started, and both groups of motors 3 drive the first gear 4 to rotate. The rotation of the first gear 4 drives the second gear 7 meshing therewith to rotate. The rotation of the first gear 4 and the second gear 7 drives the first conveying roller 6 and the second conveying roller 9 to rotate through the first rotating shaft 5 and the second rotating shaft 8 respectively, so that the inner membrane bag is conveyed to the left through the four groups of rotating rollers. The inner membrane bag passes through the workbench 10 during the sliding process. When the inner membrane bag needs to be cut, the motor 3 is turned off, the inner membrane bag stops sliding, and the inner membrane bag is placed on the workbench 10. By driving the cylinder 13, when the cylinder 13 drives the mounting plate 14 to move downward, the smoothing roller 20 on the pressing plate 19 will first contact the pressing block 18 and the inner membrane bag. After the two sets of smoothing rollers 20 abut against the inner membrane bag, the mounting plate 14 continues to move downward, causing the two sets of smoothing rollers 20 to roll away from each other, thereby smoothing the surface of the inner membrane bag and eliminating a large number of wrinkles and uneven protrusions in the inner membrane bag. At this time, the pressing block 18 presses the inner membrane bag again to achieve a better smoothing effect. After smoothing, the first cutter 15 cooperates with the second cutter 12 to cut the inner membrane bag.
