[0024] The lowest height to which the friction plate 13 can move downward is the same as the height of the outer wall at the top of the cutting table 2. The friction plate 13 is located directly above the collecting hole. The friction plate 13 is rectangular and the length between the front and rear outer walls is the same as the length of the collecting hole. Guide plates 15 are fixedly installed on the inner walls on both sides of the left and right sides of the collecting box 14. An electric upgrade rod 16 is fixedly installed on the bottom outer wall of the cutting table 2. A pressure plate 17 is fixedly installed on the telescopic shaft of the electric upgrade rod 16. The guide plate 15 is a right triangle. The shortest distance between the outer walls on the opposite sides of the two guide plates 15 is the same as the distance between the outer walls on the left and right sides of the pressure plate 17.
[0025] The cutting assembly includes a support frame 3 fixedly installed on the top of the cutting table 2, a cylinder 4 fixedly installed on the top of the support frame 3, a mounting plate 5 fixedly installed on the telescopic shaft of the cylinder 4, a positive and negative thread linear module slide 6 fixedly installed on the bottom outer wall of the mounting plate 5, sliding holes are opened on the left and right sides of the support frame 3, the telescopic shaft of the electric push rod 11 is slidably connected inside the sliding hole and the size is adapted, the minimum height of the positive and negative thread linear module slide 6 moving downward will not be less than the height of the top outer wall of the mounting seat 12, the two movable shafts of the positive and negative thread linear module slide 6 are respectively fixedly installed with a cutting tool seat 7, the left and right outer walls of the cutting tool seat 7 are fixedly installed with a spring pressure seat 8, and two support plates 9 are respectively fixedly installed on the left and right outer walls of the support frame 3.
[0026] In this embodiment, the guide sleeve 18 facilitates pouring the waste in the collecting hole into the collecting box 14 .
[0027] In this embodiment, since the gaps between the polypropylene packaging tape waste inside the collection box 14 are relatively large, which will affect the storage space inside the collection box 14, the storage space for the waste is increased after the waste is squeezed by the pressing plate 17.

[0030] The working principle of the above embodiment is:
[0031] When it is necessary to cut the polypropylene packaging tape, the cylinder 4 is started to drive the mounting plate 5 and the positive and negative tooth linear module slide 6 to move downward. At this time, the cutting knife seat 7 and the spring pressure seat 8 move downward, and the spring pressure seat 8 presses and limits the polypropylene packaging tape, and the cutting knife seat 7 cuts the excess part of the polypropylene packaging tape. When there is a lot of waste accumulated on the cutting table 2, the electric push rod 11 drives the mounting seat 12 and the friction plate 13 to move to the waste accumulation place of the cutting table 2 and is located above the waste. Then the electric telescopic rod 10 will drive the electric push rod 11 to move downward so that its friction plate 13 contacts with the waste. Then the electric push rod 11 drives the friction plate 13 to move close to the collecting hole, and moves the waste through the collecting hole and the guide sleeve 18 to the inside of the collecting box 14. When there is a lot of waste accumulated inside the collecting box 14, the electric upgrading rod 16 is started to drive the pressure plate 17 to move downward to squeeze the waste, thereby increasing the storage space for the waste.
