Description

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. The invention and development of printing presses play an important role in the spread of human civilization and culture. During the use of a double-sided printing press, after printing on one side, the paper needs to be turned over to print on the other side. During the movement of the paper, the lower side of the paper is rubbed with paper scraps and dust.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-7The present invention provides a technical solution: a deviation correction mechanism of a double-sided printing press, comprising a mounting plate 1, a moving groove is opened on the mounting plate 1, a first bracket 2 is fixedly connected to the upper side of the mounting plate 1, a transmission rod 3 is rotatably connected to the inner wall of the first bracket 2 through a bearing, a transmission roller 4 is fixedly connected to the outer wall of the left end of the transmission rod 3, the interior of the transmission roller 4 is a hollow structure, a first motor 5 is fixedly connected to the front lower surface of the mounting plate 1, a transmission belt 6 is sleeved on the output end of the first motor 5, the rear side of the transmission belt 6 is sleeved on the outer wall of the transmission rod 3, the outer wall of the transmission rod 3 is connected to the output end of the first motor 5 through the transmission belt 6, a control module 7 is fixedly connected to the side wall of the mounting plate 1, a second electrode 8 is slidably connected to the lower side of the mounting plate 1, a threaded rod 9 is fixedly connected to the output end of the second electrode 8, a moving seat 10 is threadedly connected to the outer wall of the threaded rod 9, the upper part of the moving seat 10 is located inside the moving groove, and the moving seat 10 is located inside the moving groove. A circular hole in the front-to-back direction is provided on the movable seat 10, and the inner wall of the circular hole on the movable seat 10 is slidably connected to a limit rod 11, and both ends of the limit rod 11 are slidably connected to the inner wall of the movable groove. A vibrating mechanism 12 is provided on the movable seat 10, and an adsorption mechanism 13 is provided on the left side of the transmission roller 4. A mounting groove is provided on the movable seat 10, and a conductive plate 14 is fixedly connected to the inner wall of the mounting groove, and a conductive film 15 is fixedly connected to the other side of the inner wall of the mounting groove. Both the conductive plate 14 and the conductive film 15 are made of conductive materials, and six movable seats 10 are symmetrically arranged on the left and right sides of the mounting plate 1, and the conductive plate 14, the conductive film 15, and the second electrode 8 are all electrically connected to the control module 7. When the conductive plate 14 and the conductive film 15 contact to form a passage, the control module 7 can close the second electrode 8, and a threaded groove is provided on the threaded rod 9, and the threaded groove on the left side of the threaded rod 9 and the threaded groove on the right side of the threaded rod 9 are symmetrically arranged;

[0027] During use, the paper moves forward from the rear side of the mounting plate 1, and the first motor 5 is started to drive the transmission rod 3 to rotate through the transmission belt 6. During the rotation of the transmission rod 3, the transmission roller 4 is driven to transmit the paper, so that the paper moves forward. After the paper moves and turns over, the second electrode 8 can be started to drive the threaded rod 9 to rotate. Since the moving seat 10 is limited by the limit rod 11 and cannot rotate, the threaded rod 9 will move toward the middle during the rotation. The moving seats 10 on both sides will center the paper, and the conductive film 15 will be pressed to contact the conductive plate 14 on both sides of the paper, so that the control module 7 turns off the second electrode 8. At this time, the paper is centered, and the first motor 5 is started to drive the transmission rod 3 to rotate in the opposite direction, so that the paper can be sent back to the inside of the printing press, so as to prevent the paper from being offset.

[0028] The vibrating mechanism 12 includes a deflection plate 201, a hinge groove is provided on the upper side of the moving seat 10, one side of the deflection plate 201 is hinged to the inner wall of the hinge groove, a connecting hole is provided on the moving seat 10 which penetrates from top to bottom, a first magnet 202 is fixedly connected to the lower side of the deflection plate 201, the lower side of the first magnet 202 extends to the lower side of the moving seat 10 through the connecting hole, a socket which penetrates from left to right is also provided at the lower part of the moving seat 10, a slide plate 203 is slidably connected to the inner wall of the socket, the left and right ends of the slide plate 203 are in contact with the inner wall of the moving groove, a plurality of second magnets 204 are fixedly connected to the upper side of the slide plate 203, the lower side of the first magnet 202 extends to the lower side of the moving seat 10 and contacts with the upper surface of the slide plate 203, and the upper side of the second magnet 204 has the same magnetic pole as the lower side of the first magnet 202;

[0029] In the process of the moving seats 10 on both sides moving toward the middle, the moving seats 10 push the paper to the center, and the edge of the paper is located on the upper side of the deflection plate 201. Since the outer wall of the slide plate 203 contacts the inner walls of the moving groove on both sides, the slide plate 203 cannot move in the left and right directions. When the moving seat 10 pushes the paper, the first magnet 202 will be driven to move relative to the slide plate 203. When the first magnet 202 moves, it will pass through the upper sides of several second magnets 204. Since the upper side of the second magnet 204 and the lower side of the first magnet 202 have the same magnetic pole, the first magnet 202 will be slightly pushed upward when passing through the upper side of the second magnet 204, thereby causing the deflection plate 201 to deflect slightly. In the process of the moving seat 10 pushing the paper, the deflection plate 201 will continuously drive the edge of the paper to vibrate slightly, thereby preventing the paper from being stuck with the outer wall of the moving seat 10 and the outer wall of the mounting plate 1 during the movement. Wrinkles caused by this make the paper move more smoothly, thereby avoiding paper deviation;

[0030] The adsorption mechanism 13 includes a second bracket 301, the lower side of the second bracket 301 is fixedly connected to the upper surface of the mounting plate 1, the inner wall of the second bracket 301 is fixedly connected with a fixing block 302, one side of the outer wall of the fixing block 302 extends to the inside of the transmission roller 4, the outer wall of the fixing block 302 is rotatably connected to the inner wall of the transmission roller 4 through a bearing, the inner wall of the fixing block 302 is fixedly connected with a coil 303, one side of the coil 303 extends to the right side of the inside of the transmission roller 4, and the other side of the coil 303 extends to the left side of the fixing block 302, the inner wall of the transmission roller 4 is fixedly connected with a plurality of third magnets 304, and the coil 303 is located on the left side of the fixing block 302. Both ends are fixedly connected with conductive rings 305, the outer wall of the conductive ring 305 is slidably connected with a slide seat 306, the upper surface of the mounting plate 1 is fixedly connected with a support block 308, the inner wall of the support block 308 is fixedly connected with a conductive wire 307, both ends of the conductive wire 307 are fixedly connected with the outer walls of the two slide seats 306, the coil 303 is located in the middle of a plurality of third magnets 304, and the plurality of third magnets 304 are arranged in a ring shape on the outer side of the coil 303, the conductive ring 305 and the slide seat 306 are both made of conductive materials, the upper surface height of the deflection plate 201 is consistent with the upper surface height of the mounting plate 1, and the lower side of the conductive wire 307 is higher than the upper surface of the mounting plate 1;

[0031] When the transmission roller 4 transmits the paper, the third magnet 304 will rotate rapidly around the coil 303, so that the coil 303 cuts the magnetic flux lines, so that the coil 303, the conductive ring 305, the slide 306, and the conductive wire 307 generate current, so that after the paper is turned over, the side of the paper adhering to the debris will first pass the lower side of the conductive wire 307 after turning over to the upper side. Since the conductive wire 307 is charged, it will absorb some debris that is easy to fall off, thereby reducing the amount of dust and debris adhering to the paper, and further reducing the amount of dust and debris adhering to the surface of the transmission roller 4, thereby avoiding paper deviation caused by transmission failure;

[0032] When the paper passes the lower side of the conductive wire 307 for the first time, the conductive wire 307 will heat up when the current passes through it, and the temperature of the paper is relatively high during the printing process. After being kept warm by the conductive wire 307, the temperature of the paper is relatively high when it moves to the upper side of the mounting plate 1. The front side of the mounting plate 1 is a hollow structure. After the paper moves to the front side of the mounting plate 1, the vibration of the paper caused by the movement of the moving seat 10 will make it easier for the adhesion on the surface of the paper with a higher temperature to detach, and then fall through the gap in the mounting plate 1, thereby reducing the adhesion on the surface after turning over.
