The paint cartridge 23 is bolted to the side wall of the frame 1 near the fixed roller 21, is located at the lower end of the applicator roller 22, and has a paint roller 25 rotatably connected therein, the lower end of the paint roller 25 being in contact with the paint in the paint cartridge 23, and the upper end of the paint roller 25 being in contact with the applicator sleeve 24. As shown in fig. 2, the end face of the frame 1 near the smearing mechanism 2 is provided with a scraping mechanism 3, and the scraping mechanism 3 includes a mounting frame 31 connected with the frame 1 by bolts, a steel wire 32 for scraping off excess paint, and a first fixing block 33 and a second fixing block 34 respectively connected to the end face of the steel wire 32. The mounting bracket 31 includes two mounting plates 312 parallel to each other and a connecting plate 311 connecting the two mounting plates 312, and both ends of the connecting plate 311 are respectively welded to one mounting plate 312. The first fixed block 33 and the second fixed block 34 are respectively connected to a mounting plate 312, and the steel wire 32 is parallel to the axis of the fixed roller 21 and can be contacted with the coating on the label. The coating is coated on one side of the label by the coating roller 22, then the steel wire 32 is contacted with the coating on the label, and partial coating is scraped off from the label by the steel wire 32, so that the quantity of the coating attached to the label is kept constant, the coating attached to the label is not too thick, and the waste of the coating is reduced.

As shown in fig. 2, since the paint has a certain adhesive force, after a portion of the paint is separated from the label by the steel wire 32, the portion of the paint still adheres to the surface of the label, and cannot be separated from the label, which affects the use effect of the scraping mechanism 3. Therefore, the mounting frame 31 is connected with the adsorption mechanism 4, and the adsorption mechanism 4 comprises an adsorption port 41 connected with the mounting frame 31 and an exhaust fan 42 for providing negative pressure. The opening of the suction port 41 faces the steel wire 32, and is located on the side of the steel wire 32 away from the label, and the other end of the suction port is connected with a connecting pipe 43 by a bolt, and the other end of the connecting pipe 43 is connected with an air inlet of an exhaust fan 42 by a bolt.

The coating separated from the steel wire 32 by the suction mechanism 4 is applied with a downward force to move downward against the adhesive force with the label, so that the coating is separated from the label, and the use of the scraping mechanism 3 is not affected.

As shown in fig. 3, since the paint adhered to the surface of the label is moved toward both sides of the label by upward pressure applied from the steel tape when the steel tape is used to separate a portion of the paint from the label, the paint is adhered to both side walls of the label, and the paint adhered to both side walls of the label is wasted. Therefore, the guide grooves 3122 are formed through both side walls of the mounting plate 312 that are close to each other, and the guide grooves 3122 penetrate through the side walls of the mounting plate 312 that are far from the connection plate 311. The guide grooves 3122 are each connected with a scraper 39 by a bolt, and the end faces of the two scrapers 39 close to each other can abut against both side walls of the label and can abut against the side walls of the steel wire 32. A portion of the paint attached to the side wall of the label is scraped off by the scraper 39, thereby reducing the amount of paint attached to the side wall of the label and thus reducing the waste of paint.

As shown in fig. 4, since the wire 32 is partially deformed after a long period of use, the wire 32 cannot be kept perpendicular to the axis of the fixed roller 21, which affects the use of the scraping mechanism 3. Therefore, a communicating groove 331 is formed in the side wall, close to the second fixed block 34, of the first fixed block 33, a fixing rod 321 is welded on the end face, close to the first fixed block 33, of the steel wire 32, the fixing rod 321 can penetrate through the communicating groove 331, the fixing rod is in threaded connection with an adjusting nut 35, and the end face, close to the second fixed block 34, of the adjusting nut 35 can abut against the end face, far away from the second fixed block 34, of the first fixed block 33. After the wire 32 is twisted, the adjusting nut 35 is turned to move the fixing rod 321 away from the second fixing block 34, so that the wire 32 is kept parallel to the axis of the fixing roller 21, and the using process of the scraping mechanism 3 is not affected.

As shown in fig. 5, since the steel wire 32 has paint adhered to its surface after a long period of use, the paint adhered to the surface comes into contact with the paint adhered to the label, thereby affecting the use of the steel wire 32. Therefore, the end surface of the second fixing block 34 close to the first fixing block 33 is provided with a mounting groove 341, and one end of the steel wire 32 far away from the fixing rod 321 is arranged in the mounting groove 341. An adjusting bolt 36 is connected to the side wall of the second fixing block 34 through a thread, and the adjusting bolt 36 penetrates through the second fixing block 34 and abuts the steel wire 32 against the inner wall of the mounting groove 341. The steel wire 32 is connected to the second fixing block 34 by the adjusting bolt 36, so that the steel wire 32 can be separated from the first fixing block 33 and the second fixing block 34 after the paint is adhered to the steel wire 32, and then the paint adhered to the steel wire 32 can be removed, so that the adhered paint does not affect the use of the scraping mechanism 3.

As shown in fig. 2, since the thickness of different labels is different, the distance between the steel wire 32 and the side of the label away from the paint needs to be adjusted so that the paint attached to the surface of the label after scraping is not too thin. Therefore, the adjusting grooves 3121 are penetrated through the end surfaces of the mounting plates 312, which are close to each other, and the first fixing block 33 and the second fixing block 34 are respectively placed in the adjusting grooves 3121 to slide. All be connected with a lead screw 37 in the adjustment tank 3121 rotatably, two lead screws 37 pass first fixed block 33 and second fixed block 34 respectively, and it respectively with first fixed block 33 and second fixed block 34 threaded connection.

In order to keep the steel wire 32 parallel to the fixed roller 21 during the process of driving the steel wire 32 to move by rotating the lead screw 37, as shown in fig. 2, one end of the lead screw 37 far away from the steel wire 32 is coaxially welded with a straight gear 38, an end surface of the connecting plate 311 near the straight gear 38 is rotatably connected with a rotating shaft 381, the rotating shaft 381 is coaxially welded with two bevel gears 382, the two bevel gears 382 can be respectively meshed with the straight gear 38, and the thread directions of the two lead screws 37 are opposite. The two lead screws 37 can be simultaneously rotated by the same angle by the spur gear 38, so that the first fixed block 33 and the second fixed block 34 can be moved by the same distance, and the steel wire 32 can be maintained parallel to the axis of the fixed roller 21.

As shown in fig. 4, since the surface is smooth when the adjustment nut 35 is rotated, the process of rotating the adjustment nut 35 by hand is troublesome. Therefore, two rotating blocks 351 are welded on the side wall of the adjusting nut 35, and the rotating blocks 351 are respectively positioned on two sides of the axis of the adjusting nut 35. The adjusting nut 35 is rotated by the rotating block 351, thereby facilitating the rotating process of the adjusting nut 35.
