An adjusting screw 27 is provided to rotate between the two motor plates 271. An adjusting motor 28 connected to the adjusting screw 27 is provided on the lower motor plate 271. An adjusting block 26 is screwed on the adjusting screw 27. The adjusting block 26 is slidably set in the adjusting slot 211. The side wall of the adjusting slot 211 is a lubricating layer. A tension spring 29 is connected between the adjusting block 26 and the fixed sleeve 23. The tension spring 29 pulls the fixed sleeve 23 so that the driving roller 24 can be elastically pressed against the raw material bag 3.
[0020] Depend on Figure 1 and Figure 3As shown, a T-shaped guide rail 15 is provided on the bottom plate of the main bracket 1, and a movable frame 151 is slidingly provided on the T-shaped guide rail 15.

[0021] The working principle of this utility model:
[0022] The raw material bags 3 are discharged through the rotation of the drive roller 24. As the diameter of the raw material bags 3 decreases with discharge, the adjustment motor 28 is activated, rotating the adjustment screw 27 and moving the adjustment block 26 downward, increasing the elastic potential energy of the tension spring 29. This ensures that the pressure exerted by the drive roller 24 on the raw material bags 3 allows the raw material bags 3 to rotate and discharge smoothly. During punching, the rodless cylinder 4 drives the movable frame 151, and the punching seat 16 rushes toward the pressure seat 14. The elastic pressure plate 17 first contacts the pressure seat 14, tensioning the raw material bags 3. Then, the cutter 18 enters the knife groove 141 to complete the punching of the raw material bags 3. Furthermore, the guide roller 121 ensures that the position of the raw material bags 3 remains unchanged during punching.
