[0028] Next, the packaging box sealing strip assembly tool of this exemplary embodiment will be further described.

[0029] In some embodiments of the present application, the rotating shaft 2 includes a driving portion 21 and a connecting portion 22. The diameter of the driving portion 21 is larger than the diameter of the connecting portion 22. The driving portion 21 is used for one hand of the operator to apply force, and the connecting portion 22 is used to connect with the roller 1 and the handshake 3. The roller 1 is rotatably sleeved on the connecting portion 22. The roller 1 includes a first roller 11, a second roller 12 and an extrusion portion 13. The first roller 11 and the second roller 12 are respectively and integrally connected to the two ends of the extrusion portion 13. The extrusion portion 13 is used to extrude the sealing strip 6. The thickness of the first roller 11 and the second roller 12 is 9 mm, which is adapted to the size of the packaging box 5. The roller 1 is used for limiting and extruding the sealing strip 6. That is, when extruding, the first roller 11 is placed on the inner edge of the mouth frame of the packaging box 5, the second roller 12 is placed on the outer edge of the packaging box 5, and the extrusion portion 13 is placed above the mouth frame groove. The sealing strip 6 can be pressed into the mouth frame groove by rolling along a straight line. After the sealing strip 6 is pressed into the mouth frame groove of the packaging box 5 as a whole, the first roller 11 or the second roller 12 is placed on the newly assembled sealing strip 6 to roll and extrude, and pressed again to ensure that the sealing strip 6 is assembled in place; one end of the extrusion portion 13 is connected to the first roller 11 through the first arc 14, and the other end of the extrusion portion 13 is connected to the second roller 12 through the second arc 15, wherein the radius of the first arc 14 is less than 1mm (i.e., the connection portion 22 is nearly vertically connected), and the radius of the second arc 15 is 5mm-6mm, specifically, the radius of the first arc 14 can be 0.5mm, and the radius of the second arc 15 is 5.5mm. Considering the design characteristics of the inner edge of the upper cover of the packaging box 5 being linear and the outer edge being arc-shaped, the first roller 11 and the second roller 12 are respectively designed to be linear on one side and arc-shaped on the other side, so that the roller 1 fits the inner and outer edges of the packaging box 5 and moves forward straightly without being easily deviated, and the sealing strip 6 is pressed into the mouth frame groove of the packaging box 5.
