[0030] The interior of the limiting rod 7 is connected with a movable block 10, and the movable block 10 is limited by the limiting rod 7 to prevent it from moving too much and affecting subsequent use. A connecting spring 9 is connected below the movable block 10, and a dredging block 11 is connected below the connecting spring 9. The dredging block 11 is used to dredge the feed chute to avoid blockage in film cutting. A collecting box 12 is arranged below the dredging block 11, and a fan blade 8 is arranged on the outside of the dredging block 11.

[0031] See the attached drawings in the specification Figure 1-4 The driving mechanism 3 and the protective shell 4 move in an integrated manner, the protective shell 4 and the connecting block 5 are connected in a sliding manner, the connecting block 5 and the cutter 6 are installed in an integrated manner, and the connecting block 5 and the cutter 6 are moved by the driving mechanism 3 to facilitate the film cutting work.

[0032] See the attached drawings in the specification Figure 1-4 The connection mode between the connecting block 5 and the insertion block 13 is a sliding connection, and the connection mode between the insertion block 13 and the side rod 15 is a sliding connection. A clamping block is arranged above the side rod 15. The insertion block 13 cooperates with the side rod 15 to complete the fixing and disassembly of the connecting block 5, so as to facilitate and quickly inspect and repair the cutter 6.

[0033] See the attached drawings in the specification Figure 1-4 The limiting rods 7 are symmetrically distributed on both sides of the device body 1. A slide groove is arranged inside the limiting rods 7. The limiting rods 7 are connected to the movable block 10 by sliding connection. The movable block 10 and the protective shell 4 form a magnetic adsorption structure. The limiting rods 7 cooperate with the movable block 10 so that the movable block 10 can move without affecting the film cutting work.

[0034] See the attached drawings in the specification Figure 1-4The movable block 10 forms a spring reset structure by connecting the spring 9 and the dredging block 11. The root of the dredging block 11 is evenly and equidistantly provided with anti-blocking grooves. The dredging block 11 has a trapezoidal structure. The lower part of the dredging block 11 is located inside the feed trough. The inside of the feed trough is squeezed by the dredging block 11 to prevent the cut film from accumulating inside the feed trough.

[0036] Working principle: When in use, first, the film passes through the center position of the device body 1 and is rolled up by the winding system on the other side. Before the rolling work is carried out, the position of the protective shell 4 and the cutter 6 is changed by the driving mechanism 3 until it moves to the position where the film needs to be cut. Then the driving mechanism 3 drives the protective shell 4 to descend, so that the cutter 6 contacts the film and starts the film cutting work. When the film cutting work is carried out for a long time and the cutter 6 needs to be repaired, the card block is grabbed and pulled upward, so that the card block drives the side rod 15 to move upward, so that the side rod 15 is separated from the limiting fixing work of the insertion block 13, and then the insertion block 13 is pulled out to release the limiting of the connection block 5, that is, the removal of the cutter 6 is completed;

[0037] As mentioned above, during use, the waste film cut off on both sides of the film is slowly moved toward the position of the fan blades 8 due to the rotation of the fan blades 8, and falls into the collection box 12 when it moves to the inside of the feed trough. The bottom of the dredging block 11 is provided with a groove which does not affect the discharge of the film. When the protective shell 4 moves, it is adsorbed with the movable block 10, thereby driving the movable block 10 to move, so that the movable block 10 drives the dredging block 11 below it to move, thereby moving inside the feed trough to prevent the accumulation of waste film. When the dredging block 11 moves, due to the limiting of the movable block 10, it will move up and down, always fitting into the feed trough to ensure the dredging effect.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
