[0044] As a technical optimization solution of the utility model, the four corners of the bottom of the base plate 1 are fixedly connected with supporting legs 4, and the bottoms of the supporting legs 4 are fixedly connected with anti-slip pads 5.
[0045] In this embodiment, the base plate 1 is moved to a stable ground. The legs 4 and the anti-skid pads 5 at the bottom of the base plate 1 provide stable support for the base plate 1, thereby achieving a stable support effect for the base plate 1.
[0046] As a technical optimization solution of the utility model, the front sides of the two front legs 4 are fixedly connected with a support block 11, and the front and rear sides of the top of the support block 11 are provided with limiting holes 21, and the front and rear sides of both sides of the bottom of the storage box 12 are fixedly connected with limiting columns 19, and the limiting columns 19 are movably inserted into the inside of the limiting holes 21.

[0048] As a technical optimization solution of the present utility model, a chamfer is provided on the front side of the top of the bottom plate 1 .

[0050] Working principle: First, move the bottom plate 1 to a stable ground. At this time, the legs 4 and anti-skid pads 5 at the bottom of the bottom plate 1 will provide stable support for the bottom plate 1. Then, one end of the PE vacuum packaging bag on the surface of the PE vacuum packaging bag roll 2 passes through the bottom of the conveying roller 8. Then, control the first speed regulating motor 10 and the second speed regulating motor 6 to rotate. The second speed regulating motor 6 can drive the conveying roller 8 to rotate through the output shaft. At this time, the conveying roller 8 can convey the PE vacuum packaging bag forward to the bottom of the slitting roller 14. At this time, the first speed regulating motor 10 rotates to drive the slitting roller 14 to rotate. At this time, the rotating slitting roller 14 will drive the blade 901 to alternately contact the PE vacuum packaging bag for slitting. It should be noted that the output shaft of the first speed regulating motor 10 rotates counterclockwise, so that after the blade 901 slits the PE vacuum packaging bag, it has a forward-pushing force to push the slit PE vacuum packaging bag forward into the storage box 12 for storage. This can prevent PE vacuum packaging bags from piling up on the top of the base plate 1. By controlling the rotational speeds of the first speed regulating motor 10 and the second speed regulating motor 6, the moving speed of the PE vacuum packaging bags can be controlled, and the slitting length of the PE vacuum packaging bags can be controlled. When the blade 901 needs to be replaced, the blade 901 is rotated to a suitable position, the screw 16 is removed, and the screw 16 is disengaged from the slitting roller 14. The T-shaped plug 902 can be pulled out from the T-shaped slot 903 to replace the blade 901. This can prevent the existing slitting knife from becoming dull after long-term use, which makes it inconvenient to replace, and the slitting of the packaging bags is prone to stacking on the top of the base, affecting the normal movement of the packaging bags that have not been slit, and affecting the normal slitting of the packaging bags by the slitting knife. It should be noted that there is a gap between the left side of the slitting roller 14 and the left first support plate 22, which is convenient for the screw to move.
[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
