[0033] During use, the exhaust fan 3 is started to blow air toward the bearing surface at the rear end of the conveyor belt 2 through the exhaust pipe 4. When the paper box is transferred to the rear end of the conveyor belt 2, the paper scraps in the paper box are effectively blown away, thereby effectively improving the product packaging quality.

[0034] Reference Figure 1 In the present embodiment, in order to further expand the cleaning range of the exhaust pipe 4 on the conveyor belt 2, the exhaust pipe 4 includes a main pipe 40 and a plurality of branch pipes 41, wherein the main pipe 40 is connected to the exhaust port of the exhaust fan 3, and the plurality of branch pipes 41 include at least three, one end of the three branch pipes 41 is respectively connected to the main pipe 40, and the other ends of the plurality of branch pipes 41 are distributed on the mounting frame 5, and the pipe openings of the branch pipes 41 face the bearing surface at the rear end of the conveyor belt 2, so that the air outlet is increased by the plurality of branch pipes 41, thereby effectively expanding the blowing range and improving the cleaning range of the folding box, which is practical and reliable.

[0035] Reference Figure 1In this embodiment, in order to conveniently connect the branch pipe 41 to the mounting frame 5 and make the pipe mouth of the branch pipe 41 contact the belt surface of the conveyor belt 2, the mounting frame 5 is provided including two door frames 50 connected to the conveyor belt 2 and a connecting rod 51 connecting the two door frames 50, and then a plurality of branch pipes 41 are connected to the connecting rod 51, and a plurality of branch pipes 41 are movably connected to the connecting rod 51, which not only satisfies the connection between the branch pipe 41 and the connecting rod 51, but also can adjust the distance between the branch pipes 41 by moving, so that the branch pipes 41 are suitable for cleaning cartons of different sizes.

[0036] In addition, a locking piece is provided on the connecting rod 51 for locking the branch pipe 41 on the connecting rod 51 . The branch pipe 41 is locked by using the locking piece to ensure that the structure of the branch pipe 41 is stable during use.

When in use, the branch pipe 41 is passed through the inner thread ring 60, and the outer thread sleeve 61 is rotated to connect the outer thread sleeve 61 with the inner thread ring 60, so that the branch pipe 41 is effectively connected to the connecting sleeve 6, and the connecting sleeve 6 slides on the connecting rod 51 to adjust the position of the branch pipe 41, and the provided locking piece locks the connecting sleeve 6, which has a simple structure and is easy to implement.

[0038] Reference Figure 2 In this embodiment, the locking member includes a locking bolt 7. A screw hole is provided on the connecting sleeve 6. The locking bolt 7 passes through the screw hole and is threadedly engaged with the connecting sleeve 6 until the locking bolt 7 abuts against the connecting rod 51, thereby effectively locking the connecting sleeve 6. The operation is convenient and the structure is reliable.

[0039] Reference Figure 3 In this embodiment, a fixing component is further provided at the rear end of the conveyor belt 2, and the fixing component is used to fix the paper box on the belt surface of the conveyor belt 2 to prevent the paper box from falling off the conveyor belt 2 during the process of cleaning paper scraps.
