[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0021] like Figure 1 As shown, the utility model provides a knife mark cleaning device for a conveyor belt of a die-cutting machine. The die-cutting machine is an RTC film cutting machine. The knife mark cleaning device includes an air knife cylinder 100, a sealing slide 200 and a suction assembly 300. Both ends of the air knife cylinder 100 are closed and the side wall is provided with a through groove 111 extending along its length direction. The sealing slide 200 is detachably connected to the through groove 111 of the air knife cylinder 100. The sealing slide 200 is embedded in the through groove 111 to close the middle part of the through groove 111 so that the through groove 111 on both sides of the sealing slide 200 forms two suction ports. The two suction ports are arranged opposite to the knife marks on both sides of the conveyor belt. The suction assembly 300 has a suction end, which is connected to the air knife cylinder 100 so as to form an air flow at the suction port to absorb impurities in the knife marks of the conveyor belt.

[0022] Among them, the wind knife cylinder 100 is installed near the die-cutting machine so that the through slot 111 of the wind knife cylinder 100 is set facing the conveyor belt, and the parts of the through slot 111 on both sides of the sealing slide 200 form two air suction ports, and the two air suction ports are set facing the knife marks on both sides of the conveyor belt. Under the action of the suction component 300, an air flow can be formed at the air suction port to absorb impurities in the knife marks of the conveyor belt, so as to realize the function of cleaning impurities in the knife marks. At the same time, by selecting sealing slides 200 of different lengths, the position of the air suction port can be adjusted to adapt to membranes of different specifications, so as to have a wider application.

[0023] The air knife cylinder 100 in this embodiment is attached to the conveyor belt of the die-cutting machine. In cooperation with the sealing slide 200, the two air suction ports formed thereon can face the knife marks on both sides of the conveyor belt.

[0024] To facilitate installation of the sealing strip 200 into the through-slot 111, in one embodiment, the air knife cylinder 100 includes a cylinder 110 and two end caps 120. The two ends of the cylinder 110 are detachably connected to the two end caps 120, and the through-slot 111 is formed on the sidewall of the cylinder 110. The sealing strip 200 can be first inserted into the through-slot 111, and then the two end caps 120 are connected to seal the two ends of the cylinder 110.

[0025] Since a through slot 111 is provided at the bottom of the air knife cylinder 100 , in order to prevent the air knife cylinder 100 from being deformed, in one embodiment, the air knife cylinder 100 further includes a plurality of cross fixing frames 113 installed inside the cylinder 110 .

[0026] like Figure 2 As shown, in order to avoid air leakage between the wind knife cylinder 100 and the sealing slide 200, which affects the airflow at the suction port, in one embodiment, the sealing slide 200 is fixedly connected to both sides along its length direction with a sealing strip 210, and the sealing strip 210 is embedded in the sealing groove 112 opened on the wind knife cylinder 100.

[0027] like Figure 3 As shown, during the installation of the sealing slide 200, in order to facilitate the determination of the position of the sealing slide 200 relative to the through groove 111, in one embodiment, the cleaning device also includes a positioning screw 114, and the wind knife cylinder 100 is provided with a threaded hole at the center position away from the through groove 111. The positioning screw 114 passes through the threaded hole and is embedded in the positioning hole provided at the center position of the sealing slide 200.

[0028] It is understandable that the positioning screw 114 can be disposed through one of the cross fixing frames 113 to improve the stability of the positioning screw 114 during adjustment.

[0029] In order to control the size of the air suction port, the cleaning device in this embodiment also includes two windshield slides 400, and the two windshield slides 400 are detachably connected to the through slot 111. The two windshield slides 400 are embedded in both sides of the through slot 111 to close both sides of the through slot 111. The opposite sides of the two windshield slides 400 are detachably connected to the two end covers 120 respectively, and the opposite sides of the two windshield slides 400 form two air suction ports with the two sides of the sealing slide 200 respectively.

[0030] The size of the air inlet is controlled by selecting sealing slides 200 and windshield slides 400 of different lengths. It is understandable that the structure of the windshield slide 400 is the same as that of the sealing slide 200, and no further elaboration or explanation will be given here.

[0031] In one embodiment, the cleaning device also includes two first connecting screws 121 and multiple second connecting screws 122. The two end covers 120 are connected to the corresponding windshield slide 400 via a first connecting screw 121, and the two end covers 120 are connected to the cylinder 110 via multiple second connecting screws 122.

[0032] The suction assembly 300 in this embodiment includes a blower 310, a filter 320, and an air duct 330 connected in sequence. The air duct 330 is connected to a through hole formed in one end cap 120. The blower 310 provides an air source, and the air duct 330 sucks foreign matter from the cut into the filter 320.

[0033] To facilitate the introduction of foreign matter in the cylinder 110 into the air duct 330, in one embodiment, the end cover 120 is connected to the air duct 330, and the side of the end cover 120 close to the cylinder 110 is a conical surface, and the cross-section of the conical surface gradually decreases in the direction close to the end cover 120.

[0034] In one embodiment, the cross section of the sealing slide 200 is in the shape of an I. It is understood that the sealing slide 200 can also be implemented in other shapes, which is not limited to this.

[0035] Compared with the existing technology: the air knife cylinder 100 is installed near the die-cutting machine so that the through slot 111 of the air knife cylinder 100 is facing the conveyor belt, and the through slot 111 is located on both sides of the sealing slide 200 to form two air suction ports, and the two air suction ports are facing the knife marks on both sides of the conveyor belt. Under the action of the suction component 300, an air flow can be formed at the air suction port to absorb impurities in the knife marks of the conveyor belt, so as to realize the function of cleaning impurities in the knife marks. At the same time, by selecting sealing slides 200 of different lengths, the position of the air suction port can be adjusted to adapt to membranes of different specifications, and the application is more extensive.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
