Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses cleaner of printing machine paper feeding mechanism china ink dirt. Referring to fig. 1-3, a clearer of ink stains of a paper feeding mechanism of a printing machine, including two supporting plates 1, the common swing joint in relative one side of two supporting plates 1 has a paper feeding roller 4, rotate through paper feeding roller 4, form paper in the time of working, for prior art, no longer describe, the right side upper end fixedly connected with motor 2 of right side supporting plate 1, for drive arrangement, the left side of motor 2 rotates and is connected with reciprocal lead screw 3, the pole wall meshing of reciprocal lead screw 3 is connected with movable block 6, motor 2 drives reciprocal lead screw 3 to rotate, reciprocal lead screw 3 drives movable block 6 and controls reciprocating motion, both ends all swing joint has stopper 11 about the inner wall of movable block 6, both ends all swing joint has scraper blade 10 about the inner wall of movable block 6, make scraper blade 10 can only carry out unidirectional rotation through stopper 11, the right side fixedly connected with spring 12 of scraper blade 10, can keep the operating position that scraper blade 10 removed through spring 12.

As shown in fig. 2-3, the lower ends of the two support plates 1 are fixedly connected with a threaded rod 5, the inner lower end of the moving block 6 is rotatably connected with a gear 13, the inner part of the gear 13 is in spiral transmission with the rod wall of the threaded rod 5, when the moving block 6 drives the gear 13 to move, the gear 13 rotates under the action of the threaded rod 5, the inner wall of the moving block 6 is rotatably connected with a rotating block 7, the outer side of the rotating block 7 is uniformly rotatably connected with a tooth block 14, the tooth block 14 is meshed with the gear 13, the gear 13 rotates to the rotating block 7 through the tooth block 14, the rotating block 7 is rotatably connected with a scraper 10, the rotating block 7 rotates to drive the scraper 10 to rotate, a limit block 11 is fixedly connected with the rotating block 7, the left side of the inner wall of the rotating block 7 is fixedly connected with a sponge 8, the sponge 8 absorbs undried ink dirt, the left side of the paper feeding roller 4 is clamped with the right side of the left support plate 1, the left side of the reciprocating screw rod 3 and the left side of the threaded rod 5 are both provided with a clamping block 9, and the clamping block 9 is removed, so that the whole device can be disassembled to facilitate later maintenance and replacement, and the scraper 10 is made of rubber.

The implementation principle of the cleaner for the ink stains of the paper feeding mechanism of the printing machine is as follows: when the cleaning device works, the motor 2 is electrified to work, the motor 2 drives the reciprocating screw rod 3 to rotate, the reciprocating screw rod 3 rotates to enable the moving block 6 to move left and right, when the moving block 6 moves left, the friction force between the scraper 10 and the paper feeding roller 4 moves right, at the moment, the scraper 10 moves right, the acting force between the scraper 10 and the paper feeding roller 4 is small, when the moving block 6 moves right, the friction force between the scraper 10 and the paper feeding roller 4 moves left, at the moment, the scraper 10 is perpendicular to the paper feeding roller 4 under the action of the limiting block 11, and therefore the scraper 10 can drag ink dirt on the paper feeding roller 4 to one side, and the cleaning effect is improved;

further, the moving block 6 drives the gear 13 to move when moving, because the gear 13 and the threaded rod 5 are in spiral transmission, when the gear 13 moves, certain rotation can occur, because the surface of the rotating block 7 is fixedly connected with the tooth block 14 and is meshed with the gear 13, the gear 13 rotates to drive the rotating block 7 to rotate, the rotating block 7 drives the scraper 10 to rotate correspondingly, and therefore, when horizontal cleaning is conducted, relative rotation cleaning is conducted, and the cleaning effect is improved.
