Description

Technical Field

[0001] The invention relates to the technical field of printing, and in particular to a printing device for packaging and decoration printed matter. Background Art

[0002] Printing is the technology of batch copying the contents of original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. through plate making, inking, pressurization and other processes, so that the ink is transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] In the prior art, for example, Chinese invention patent CN116281286B discloses a printing device for packaging and decoration printed materials, including a printer body and a packaging carton, the interior of the printer body is fixedly connected to a conveyor platform, the interior of the conveyor platform is provided with an electric drive belt for transmission, the front side of the printer body is provided with a conveyor component for fast loading, the side of the conveyor component is provided with a transmission component for transmission, a longitudinal positioning component is provided in the conveyor component, and transverse positioning components are provided on both sides of the conveyor component close to the conveyor platform. The transverse positioning component uses a limit plate to limit the transverse position of the packaging carton, and at the same time, the abutment plate and the limit plate both use reciprocating intermittent motion, so that when the packaging carton rises and falls to the position above the conveyor platform for placement, the conveyor platform is simultaneously limited in the transverse and longitudinal directions, thereby improving the convenience of transporting the packaging carton while ensuring the accuracy of the position of the packaging carton when placed.

[0004] However, the above patent still has certain shortcomings. The position of the printed part needs to be adjusted before printing. In the automated production workshop, conveying equipment is usually used to transport it. Direct transmission will cause the material to be shaken and offset. It is difficult to adjust the position of the material before transmission. The position between the printed part and the printing plate is not accurately aligned, resulting in the offset of the printed image. This not only affects the visual effect of the printed product, but also may make it impossible to correctly read or identify key information. If position problems occur frequently, it is necessary to stop the machine for adjustment. Not only does it interrupt the production process, but it also reduces production efficiency and prolongs the production cycle.

[0051] A front correction component 7 is provided on the conveying device 1, and the front correction component 7 is located on one side of the side correction component 2. The front correction component 7 includes a guide seat 74 fixed to the top of the first fixed seat 27, a lower pressure rod 71 is slidably provided inside the guide seat 74, an electric telescopic rod 73 is fixedly provided on the top of the lower pressure rod 71, and the outer shell of the electric telescopic rod 73 is fixedly connected to the top of the guide seat 74, a front correction plate 72 is rotatably provided at the bottom end of the lower pressure rod 71, and a reset torsion spring is fixedly provided between the front correction plate 72 and the lower pressure rod 71, and the front correction plate 72 is inclined to the top of the conveyor belt 13;

[0052] The connecting shaft 121 is inserted into the inner rotating cylinder 22, and a movable through hole is opened at one end of the outer fixed cylinder 21 close to the connecting shaft 121, and the inner diameter of the movable through hole is larger than the diameter of the connecting shaft 121. An inner fixed plate 241 is fixedly arranged on the arc-shaped outer wall of the port plate 24, and a plurality of outer rotating plates 251 are rotatably arranged on the inner wall of the transmission ring 25, and the plurality of outer rotating plates 251 are distributed in a ring array, and an outer stopper 252 is fixed on one side of each outer rotating plate 251 on the inner wall of the transmission ring 25, and an outer torsion spring 253 is fixed between the inner wall of the transmission ring 25 and each outer rotating plate 251;

[0053] The guide groove 221 includes a plurality of straight slide grooves 222, and the plurality of straight slide grooves 222 are distributed in a ring array on the outer wall of the inner drum 22, and the guide groove 221 also includes a plurality of inclined grooves 223, and each inclined groove 223 is connected to one end of each straight slide groove 222;

[0054] A damper 272 sleeved on the outer wall of the plug rod 26 is fixedly connected to one side of the first fixing seat 27, and a return spring 271 fixedly connected to the end of the plug rod 26 is fixed to the other side of the first fixing seat 27. The return spring 271 is sleeved on the outer side of the plug rod 26, and the plug rod 26 is inserted into the first fixing seat 27.

[0055] The second fixing seat 29 and the first fixing seat 27 are symmetrically arranged about the vertical center axis of the roller 12, and the motor body 14 is installed on the outer wall of the bracket body 11;

[0056] The motor body 14 is connected to the rotating shaft through a coupling. A discharge transfer device 6 is provided on the other side of the conveying device 1 . A printing device 5 is provided on one side of the conveying device 1 . The conveying device 1 and the discharge transfer device 6 are respectively located on both sides of the printing device 5 .

[0057] By starting the motor body 14, the roller 12 fixedly connected to the rotating shaft can be driven to rotate under the connection of the rotating shaft, thereby driving the conveyor belt 13 to roll, and at the same time, the conveyor belt 13 can pull the roller 12 near the side of the external fixed cylinder 21 to rotate. When the conveyor belt 13 drives the printed piece 4 to move between the first correction plate 28 and the second correction plate 291 for the first time, the electric telescopic rod 73 can be started to push the pressing rod 71 and the front correction plate 72 to move downward. When the bottom end of the front correction plate 72 contacts the top end of the conveyor belt 13, as the pressing rod 71 continues to slide, and because the front correction plate 72 and the top end of the conveyor belt 13 are inclined, The electric telescopic rod 73 can push the front correction plate 72 to rotate around the contact position with the lower pressure rod 71, and at the same time squeeze the reset torsion spring, so that the bottom end of the front correction plate 72 can slide along the top of the conveyor belt 13. At this time, the front correction plate 72 can contact the side of the printed piece 4 close to the front correction plate 72, and then push the printed piece 4 to slide on the top of the conveyor belt 13. In this process, the printed piece 4 can be pushed from the inside of the first correction plate 28 and the second correction plate 291 to the outside thereof. Due to the friction between the bottom end of the printed piece 4 and the top of the conveyor belt 13, the printed piece 4 can be close to the side of the front correction plate 72 and gradually become vertical with the first correction plate 28. Thereby, the front end position of the printing piece 4 is corrected. At the same time, the roller 12 close to the outer fixed cylinder 21 can drive the connecting shaft 121 to rotate, and then drive the port disk 24 fixedly connected thereto to rotate, and drive the inner fixed plate 241 fixedly connected to the outer wall of the port disk 24 to make a circular motion. With the continuous rotation of the port disk 24, the other side of the inner fixed plate 241 can be tightly attached to the outer rotating plate 251. At this time, the outer rotating plate 251 can pull the transmission ring 25 to rotate under the obstruction of the outer stopper 252. Since the outer wall of the transmission ring 25 is fixedly connected to the inner wall of the inner rotating cylinder 22, the inner rotating cylinder 22 can be driven to rotate around the position connected to the outer fixed cylinder 21. During this process, the guide block 231 can gradually slide from the end of the straight sliding groove 222 close to the connecting shaft 121 to the end of the inclined groove 223 away from the connecting shaft 121, and slide along the inclined surface of the inclined groove 223. At the same time, the guide block 231 can gradually move from the left side of the inner rotating cylinder 22 to the right side thereof, and drive the reciprocating sliding cylinder 23 fixed thereto to slide along the inner wall of the outer fixed cylinder 21, so that the external connecting rod 232 fixed on the outside of the outer fixed cylinder 21 moves from left to right. The movement of the external connecting rod 232 can pull the first correcting plate 28 fixed thereto gradually away from the second correcting plate 291, and compress the return spring 271 located between the plug-in rod 26 and the first fixed seat 27.

[0058] When the front end of the printed piece 4 is corrected, the electric telescopic rod 73 is started to drive the pressing rod 71 to rise. With the continuous transmission of the conveyor belt 13, when the printed piece 4 moves from the outside between the first correction plate 28 and the second correction plate 291 to the inside thereof again, the motor body 14 is controlled to stop the rotation of the shaft. At this time, the printed piece 4 is in a relatively static state. At the same time, the guide block 231 slides to the end of the inclined groove 223 away from the connecting shaft 121 and is at the connecting end of the straight groove 222 and the inclined groove 223. At this time, the guide block 231 is not blocked. Due to the reciprocating The connection between the slide 23, the external rod 232 and the plug-in rod 26 allows the plug-in rod 26 to slide on the inner wall of the first fixed seat 27. At the same time, under the action of the reset spring 271 and the damper 272, the plug-in rod 26 can be gradually reset. The setting of the damper 272 can prevent the plug-in rod 26 from pushing the first positioning plate 28 to quickly reset and move, causing damage to the printed part 4. The sliding of the plug-in rod 26 can reset the first positioning plate 28 fixed at its end, thereby correcting the position of the printed part 4 located between the first positioning plate 28 and the second positioning plate 291.

[0059] In this embodiment, a guide block 231 slidably connected to the outer wall of the inner rotating cylinder 22 is fixedly connected to the inner wall of the reciprocating slide cylinder 23, and a guide groove 221 matching the guide block 231 is opened on the arc-shaped outer wall of the inner rotating cylinder 22, one end of one of the rollers 12 is fixedly connected to a connecting shaft 121, the other end of the connecting shaft 121 is fixedly connected to a port disk 24, and the inner wall of the inner rotating cylinder 22 is fixedly connected to a transmission ring 25 sleeved on the outer side of the port disk 24;

[0060] A cleaning component 3 extending to the top of the conveying device 1 is provided on one side of the side correction component 2, and the cleaning component 3 includes a connecting rod 31 fixedly connected to the end of the port disk 24, and the other end of the connecting rod 31 is fixedly connected to a cleaning rotating seat 32 rotatably connected to the inner rotating cylinder 22, and a fixed box 33 is fixed to the side of the bracket body 11 close to the outer fixed cylinder 21, and the fixed box 33 is located on one side of the cleaning rotating seat 32, and a connecting piece is fixedly arranged between the fixed box 33 and the bracket body 11, and a transmission groove is provided on the side of the fixed box 33 close to the cleaning rotating seat 32, and a cleaning lever 321 is fixedly connected to the arc-shaped outer wall of the cleaning rotating seat 32, and the cleaning lever 321 can enter the interior of the fixed box 33, and a lifting plate 34 is slidably connected to the interior of the fixed box 33, and an adjusting seat 331 is fixedly connected to the outer wall of the lifting plate 34 close to the interior of the fixed box 33, and a first adjusting plate 332 is rotatably provided on the outer wall of the adjusting seat 331 close to the cleaning lever 321, and the outer wall of the adjusting seat 331 is rotatably provided with a first adjusting plate 332, and the outer wall of the adjusting seat 331 is rotatably provided with a first adjusting plate 332 A second adjusting plate 333 is rotatably arranged at a wall located below the first adjusting plate 332, a total magnetic seat 334 is fixed to an outer wall of the lifting plate 34 away from the adjusting seat 331, a first magnetic seat 335 and a second magnetic seat 336 are fixedly connected to the inner wall of the fixed box 33, a first limiting block is fixed to an outer wall of the adjusting seat 331, and the bottom end of the first limiting block contacts the top end of the first adjusting plate 332, a first limiting torsion spring is fixed between the first adjusting plate 332 and the adjusting seat 331, a second limiting torsion spring is fixed to an outer wall of the adjusting seat 331, and the top end of the second limiting block contacts the bottom end of the second adjusting plate 333, a second limiting torsion spring is fixed between the adjusting seat 331 and the second adjusting plate 333, a cleaning frame 35 is fixed to an outer wall of the lifting plate 34 away from the fixed box 33, a cleaning scraper 36 is fixed inside the cleaning frame 35, and a brush is fixed to the cleaning scraper 36 on the side close to the printing device 5, and both the brush and the cleaning scraper 36 contact the top end of the conveyor belt 13.

[0061] When it is necessary to clean the top of the conveyor belt 13, the motor body 14 is controlled to drive the rotating shaft to reverse, and the connecting shaft 121 can be driven to reverse under the connection of the two rollers 12 and the conveyor belt 13. At this time, the port disk 24 is reversed, so that the inner fixed plate 241 contacts with multiple outer rotating plates 251 one by one, and the multiple outer rotating plates 251 can rotate around the transmission ring 25 one by one, and squeeze the multiple outer torsion springs 253 one by one. Since there is a certain friction between the inner fixed plate 241 and the outer rotating plate 251, the inner drum 22 will rotate with the port disk 24. When cleaning is required There is a certain uncertainty. If the guide block 231 is in the inclined groove 223, the guide block 231 can slide toward the side close to the connecting shaft 121 under the action of the reset force of the reset spring 271 and the friction between the inner fixed plate 241 and the outer rotating plate 251. When the guide block 231 slides to the connection between the inclined groove 223 and the straight slide groove 222, the guide block 231 at this time cannot slide along the straight slide groove 222 and cannot move due to the obstruction of the straight slide groove 222. Therefore, the transmission ring 25 will not rotate with the port disk 24 due to the friction.

[0062] The rotation of the port plate 24 can drive the cleaning swivel seat 32 to rotate and drive the cleaning lever 321 to make a circular motion. As the cleaning swivel seat 32 continues to rotate, the bottom end of the cleaning lever 321 can contact the top end of the second adjustment plate 333. At this time, under the limit of the second limit block, the second adjustment plate 333 will cause the lifting plate 34 fixed on one side of the adjustment seat 331 to slide downward, and drive the cleaning frame 35 fixedly connected to the lifting plate 34 to slide downward. When the bottom end of the brush of the cleaning scraper 36 contacts the top end of the conveyor belt 13, the total The magnetic seat 334 can be adsorbed with the second magnetic seat 336. As the conveyor belt 13 continues to roll, the brush can automatically clean the dust adhered to the top of the conveyor belt 13. After the cleaning rotating seat 32 rotates one circle, the bottom end of the cleaning lever 321 contacts the top of the first adjustment plate 332, which can push the first adjustment plate 332 to rotate around the contact position with the adjustment seat 331 and squeeze the first limiting torsion spring. When the cleaning lever 321 is separated from the first adjustment plate 332, the first adjustment plate 332 can be reset under the action of the first limiting torsion spring.

[0063] After cleaning is completed, the motor body 14 can be controlled to rotate forward, and with the cooperation of the side correction component 2, the top end of the cleaning lever 321 can contact the bottom end of the first adjustment plate 332. At this time, the first adjustment plate 332 is limited by the first limit block, so that the lifting plate 34 fixed on one side of the adjustment seat 331 slides upward. When the cleaning scraper 36 and the brush move to above the printed part 4, the total magnetic seat 334 can be adsorbed with the first magnetic seat 335 to prevent the cleaning scraper 36 and the brush from falling due to their own weight.

[0064] The working principle of the device is as follows: by starting the motor body 14, the roller 12 fixedly connected to the rotating shaft can be driven to rotate under the connection of the rotating shaft, thereby driving the conveyor belt 13 to roll, and at the same time the conveyor belt 13 can pull the roller 12 near the side of the outer fixed cylinder 21 to rotate. When the conveyor belt 13 drives the printed piece 4 to move between the first correction plate 28 and the second correction plate 291 for the first time, the electric telescopic rod 73 can be started to push the lower pressure rod 71 and the front correction plate 72 to move downward. When the bottom end of the front correction plate 72 contacts the top end of the conveyor belt 13, as the lower pressure rod 71 continues to slide, and because the front correction plate 72 and the top end of the conveyor belt 13 are inclined, the electric telescopic rod 73 can push the front correction plate 72 around the lower pressure rod 71. The rod 71 rotates at the contact position and squeezes the reset torsion spring at the same time, so that the bottom end of the front correction plate 72 can slide along the top of the conveyor belt 13. At this time, the front correction plate 72 can contact the side of the printed piece 4 close to the front correction plate 72, and then push the printed piece 4 to slide on the top of the conveyor belt 13. In this process, the printed piece 4 can be pushed from the inside of the first correction plate 28 and the second correction plate 291 to the outside thereof. Due to the friction between the bottom end of the printed piece 4 and the top of the conveyor belt 13, the printed piece 4 can be close to one side of the front correction plate 72 and gradually become perpendicular to the first correction plate 28, thereby correcting the front end position of the printed piece 4. At the same time, the roller 12 close to the external fixed cylinder 21 can drive the connecting shaft 121 to rotate, and then drive the connecting shaft 121 fixed to it. The port plate 24 connected to the port plate 24 rotates, driving the inner fixed plate 241 fixedly connected to the outer wall of the port plate 24 to make a circular motion. As the port plate 24 continues to rotate, the other side of the inner fixed plate 241 can be tightly attached to the outer rotating plate 251. At this time, the outer rotating plate 251 can pull the transmission ring 25 to rotate under the obstruction of the outer stopper 252. Since the outer wall of the transmission ring 25 is fixedly connected to the inner wall of the inner rotating cylinder 22, the inner rotating cylinder 22 can be driven to rotate around the position connected to the outer fixed cylinder 21. In this process, the guide block 231 can gradually slide from the end of the straight sliding groove 222 close to the connecting shaft 121 to the end of the inclined groove 223 away from the connecting shaft 121, and slide along the inclined surface of the inclined groove 223. At the same time, the guide block 231 can gradually move from the left side of the inner rotating cylinder 22 to the left side of the inner rotating cylinder 22. The outer rod 232 fixed to the outer fixed tube 21 moves from left to right. The movement of the outer rod 232 can pull the first correcting plate 28 fixed to it gradually away from the second correcting plate 291, and compress the return spring 271 between the plug-in rod 26 and the first fixed seat 27. When the front end of the printed piece 4 is corrected, the electric telescopic rod 73 is started to drive the pressing rod 71 to rise. With the continuous transmission of the conveyor belt 13, when the printed piece 4 moves from the outer side to the inner side between the first correcting plate 28 and the second correcting plate 291 again, the motor body 14 is controlled to stop the rotation of the rotating shaft. At this time, the printed piece 4 is in a relatively static state. At the same time,The guide block 231 slides to the end of the inclined groove 223 away from the connecting shaft 121 and is at the connecting end of the straight groove 222 and the inclined groove 223. At this time, the guide block 231 is not blocked. Due to the connection between the reciprocating slide 23, the external rod 232 and the plug rod 26, the plug rod 26 can slide on the inner wall of the first fixed seat 27. At the same time, under the action of the reset spring 271 and the damper 272, the plug rod 26 can be gradually reset. The setting of the damper 272 can prevent the plug rod 26 from pushing the first correcting plate 28 to quickly reset and move, causing damage to the printed part 4. The sliding of the plug rod 26 can make The first correction plate 28 fixed at its end is reset, so as to correct the position of the printed piece 4 between the first correction plate 28 and the second correction plate 291. When it is necessary to clean the top of the conveyor belt 13, the motor body 14 is controlled to drive the rotating shaft to reverse, and the connecting shaft 121 can be driven to reverse under the connection of the two rollers 12 and the conveyor belt 13. At this time, the port plate 24 is reversed, so that the inner fixed plate 241 contacts with multiple outer rotating plates 251 one by one. At the same time, the multiple outer rotating plates 251 can rotate around the transmission ring 25 one by one and squeeze the multiple outer torsion springs 253 one by one. There is a certain friction between the plates 251, which will cause the inner drum 22 to rotate with the port disk 24. Since there is a certain uncertainty in the time required for cleaning, if the guide block 231 is inside the inclined groove 223, the guide block 231 can slide toward the side close to the connecting shaft 121 under the action of the reset force of the reset spring 271 and the friction between the inner fixed plate 241 and the outer rotating plate 251. When the guide block 231 slides to the connection between the inclined groove 223 and the straight groove 222, the guide block 231 at this time cannot slide along the straight groove 222, and due to the resistance of the straight groove 222, the guide block 231 is not able to slide along the straight groove 222. The stopper cannot move, so the transmission ring 25 will not rotate with the port disk 24 due to friction. After cleaning, the motor body 14 can be controlled to rotate forward, and with the cooperation of the side correction component 2, the top of the cleaning lever 321 is in contact with the bottom of the first adjustment plate 332. At this time, the first adjustment plate 332 is limited by the first limit block, so that the lifting plate 34 fixed on one side of the adjustment seat 331 slides upward. When the cleaning scraper 36 and the brush move to the top of the printing piece 4, the main magnetic seat 334 can be adsorbed with the first magnetic seat 335 to prevent the cleaning scraper 36 and the brush from falling due to their own weight.
