[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1 and Figure 2 As shown, this application provides a cutting device for a film slitting machine, including a connecting roller 1, a cutting tool 2, and a mounting base 3. The cutting tool 2 is fixedly mounted on the surface of the connecting roller 1. The connecting roller 1 rotates on the slitting machine via a bearing seat. The slitting machine is equipped with a motor that is drively connected to the connecting roller 1. When the motor is actuated, the connecting roller 1 and the cutting tool 2 rotate. The rotating cutting tool 2 will slit the film. The mounting base 3 is fixedly mounted on the slitting machine by bolts. The mounting base 3 is formed with a relief groove 4. The part of the film slit by the cutting tool 2 will rotate into the relief groove 4. After a period of time, it will rotate out of the relief groove 4 again.

[0023] like Figure 2 and Figure 3 As shown, two sets of contact components are rotatably arranged in the clearance groove 4. The contact components include a support, a sponge sleeve 5, and a partition 6. The partition 6 is fixedly installed on the mounting base 3 with fixing screws. The clearance groove 4 is divided into a cleaning area 7 and a slag collection area 8 by the partition 6. The support is fixedly installed on the mounting base 3, and the position of the support corresponds to the partition 6. A rotating sleeve 9 is fixedly connected to the inside of the sponge sleeve 5. The rotating sleeve 9 is sleeved on the outside of the support and rotatably connected to the support. Both the sponge sleeve 5 and the rotating sleeve 9 pass through the partition 6, so that a part of the sponge sleeve 5 is located in the cleaning area 7 and the other part of the sponge sleeve 5 is located in the slag collection area 8. The sponge sleeve 5 located in the cleaning area 7 will come into contact with the tool 2.

[0024] When the connecting roller 1 rotates, the sponge sleeve 5 located in the cleaning zone 7 will come into contact with the cutter 2, causing the sponge sleeve 5 and the rotating sleeve 9 to rotate. The sponge sleeve 5 can absorb impurities on the cutter 2 by contacting the cutter 2, so that the impurities on the cutter 2 will not affect the cutting operation of that part of the cutter 2 again, thus improving the cutting quality.

[0025] like Figure 2 and Figure 3As shown, the rotating sleeve 9 has several through holes 10. The rotating sleeve 9 and the support member are combined to form a flow space. The support member includes an air intake part and an air blowing part. The air intake part uses an air intake pipe 11 and the air blowing part uses an air blowing pipe 12. Both the air intake pipe 11 and the air blowing pipe 12 have air ports on their surfaces. The air intake pipe 11 and the air blowing pipe 12 are connected by a connecting pipe 13. An air pipe connector is fixedly installed on the connecting pipe 13. When the air pipe connector is connected to the air pipe, the gas in the air pipe flows towards the air blowing pipe 12 and then flows out through the opening and the air port of the air blowing pipe 12. The air intake pipe 11 will be drawn in through the opening and the air port of the air intake pipe 11 due to the increased gas flow speed in the air blowing pipe 12. At the same time, the air ports of the air intake pipe 11 and the air blowing pipe 12 are inclined away from the connecting pipe 13.

[0026] When the sponge sleeve 5 in the cleaning zone 7 comes into contact with the cutting tool 2, the suction pipe 11 passes through the flow space, the through-hole, and the gap of the sponge sleeve 5, giving the sponge sleeve 5 suction. Impurities are kept on the surface of the sponge sleeve 5 due to the suction. When the part of the sponge sleeve 5 with impurities is rotated to the corresponding slag collection zone 8, the blowing pipe 12 passes through the flow space, the through-hole, and the gap of the sponge sleeve 5, causing the sponge sleeve 5 to blow air, which blows the impurities into the slag collection zone 8, cleaning the sponge sleeve 5, so that the sponge sleeve 5 can clean the cutting tool 2 again.

[0027] In summary, the cutting device provided in this embodiment cleans impurities on the surface of the cutting tool 2, ensuring that the impurities on the cutting tool 2 do not affect the subsequent cutting operation of that part of the cutting tool 2, thereby improving the cutting quality.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
