The imprinting device drives a polarizing plug or a zoom plug to be inserted into a relay roller or a first powered roller by manually rotating a switching handle in a switching assembly, and then the relay roller drives the polarizing screw to rotate, the first powered roller drives the zoom screw to rotate, the polarizing screw drives the polarizing ball to slide horizontally, and the zoom screw drives the zoom ball to slide horizontally, so as to realize the polarization adjustment and zoom adjustment functions. The inking device drives the toner to fill the first toner chamber and the second toner chamber through the weight of the toner and the suction of the powder pump. When the photosensitive printing cylinder contacts the toner at the first ink outlet and the second ink outlet, the negatively charged toner will be adsorbed onto the surface of the photosensitive printing cylinder, and the toner that is not adsorbed will be blocked at the outlet of the first ink outlet and the second ink outlet to prevent the occurrence of powder falling.

Description

Technical Field

[0001] The invention relates to the technical field of double-sided printing, in particular to a synchronous double-sided printing machine. Background Art

[0002] Traditional printing machines generally print on one side. When only one side is required, fast large-scale printing can be achieved. At the same time, the single-sided printing method also makes the structure of the printing machine simpler, which can further reduce the failure rate. However, when double-sided printing is required, a single-sided printing machine can only print one side at a time, and the paper needs to be turned over when printing the other side. This will result in the printing efficiency cannot be further improved, and it also increases the probability of printed products being scrapped due to operational errors.

[0003] In view of the defects of single-sided printing presses, the prior art has made corresponding modifications to single-sided printing presses, thereby obtaining double-sided printing presses that can perform double-sided printing; however, the existing double-sided printing presses often use a turning mechanism to turn over the first side after printing, or set the two printing mechanisms at a larger distance to avoid interference between the upper and lower sides during double-sided printing; therefore, the existing double-sided printing presses cannot perform synchronous double-sided printing and cannot further improve the printing efficiency; when the existing printing presses are rubbing the paper, the static electricity between the papers often causes the papers to be adsorbed together, thereby causing multiple papers to be rubbed into the printing mechanism at the same time; therefore, a synchronous double-sided printing press that can perform double-sided printing synchronously and prevent multiple papers from being rolled into the machine at the same time is needed to solve the shortcomings of the existing double-sided printing presses.

[0004] For example, the patent with announcement number CN106739546B provides a double-sided printer, which includes a frame, a cloth-feeding roller, a cloth-collecting roller, a first printing platform, a visual recognition device, a second printing platform, and a control box. The visual recognition device is used to fine-tune the position of the printed paper, and the first printing platform and the second printing platform are used for printing on both sides. This application can ensure the accuracy of double-sided printing alignment. Although this solution can achieve double-sided printing, it cannot achieve synchronous double-sided printing, and cannot further improve the efficiency of printing; at the same time, the prior art can only manually adjust and clean the lens in the printing platform, and cannot achieve automatic cleaning and rapid adjustment, and cannot further improve the service life; in the inking process of the prior art, the toner needs to be transferred to the transfer roller by the rotation of the developing roller, and this process will be caused by the vibration or failure of the printer itself, causing the toner to fall from the developing roller, thereby affecting the printing effect.

The corresponding heating resistor 405 is heated after being energized, which will drive the residual gas in the oil cylinder 404 to expand, and the expanded gas will drive the positioning push rod 403 to extend outward through the ink, thereby driving the paper to deflect accordingly, so as to realize the auxiliary alignment function of the paper; then the paper is first The front blank of the paper is pushed forward between the two second heating rollers 312, the two first motors 309 drive the two first heating rollers 311 to rotate synchronously and oppositely, the two first heating rollers 311 respectively drive the two second heating rollers 312 to rotate, and the two second heating rollers 312 drive the front blank of the paper to continue to move until the front blank of the paper is sent out from the imprint housing 301, and then observe whether there is residual toner in the front blank of the paper to preliminarily judge whether there is a problem with the printing press; then the two first heating rollers 311 and the two second heating rollers 312 in the imprint device 3 drive the remaining paper to continue to move forward, and this When the second motor 318 drives the first power-on roller 316 to rotate, the first power-on roller 316 drives the photosensitive component 505 at the upper end of the stamping shell 301 to rotate through the first transmission belt 319, the first power-on roller 316 also drives the relay roller 313 to rotate in the opposite direction through the first gear 314 and the second gear 315, and the relay roller 313 drives the photosensitive component 505 at the lower end of the stamping shell 301 to rotate through the second transmission belt 320, so as to realize the synchronous reverse rotation of the two ink printing devices 5, and at the same time, the first power-on roller 316 and the second power-on roller 317 respectively drive the photosensitive component 505 at the upper end of the stamping shell 301 and the photosensitive component 505 at the lower end of the stamping shell 301 The photosensitive component 505 applies a positive charge; after the positive charge is applied, the laser emitter 508 on the ink holder 501 emits a laser, which is focused by the second convex lens 507 and reaches the four-prism lens 509, and then refracted by the four-prism lens 509 and focused by the first convex lens 506 to reach the surface of the photosensitive printing cylinder 512. By controlling the rotation speed of the four-prism lens 509 and controlling the emission of the laser emitter 508, the surface of the photosensitive printing cylinder 512 is accurately irradiated, so that the irradiated area on the photosensitive printing cylinder 512 becomes a conductor to release the positive charge, and the remaining unirradiated area retains the positive charge;Subsequently, the inking device 2 drives the toner to fill the first toner chamber 205 and the second toner chamber 207 through the weight of the toner in the ink cartridge 201 and the suction force of the powder pump 203. When the positively charged area of ​​the photosensitive printing cylinder 512 contacts the toner at the first ink outlet 206 and the second ink outlet 208, the negatively charged toner is adsorbed onto the surface of the photosensitive printing cylinder 512. At the same time, the toner in the first toner chamber 205 and the second toner chamber 207 is squeezed outward by the subsequent toner. When the toner is squeezed to the first ink outlet 206 and the second ink outlet 208, the toner in the first toner chamber 205 and the second toner chamber 207 is squeezed outward by the subsequent toner. When the toner is at the outlet, the shapes of the first ink outlet 206 and the second ink outlet 208 prevent the toner from falling out in large quantities, thereby preventing the toner from falling out. While the two photosensitive components 505 are rotating, the switching handle 322 in the switching component 303 is manually rotated. The switching handle 322 drives the polarizing rod 306 to be inserted into the polarizing screw 305 and the relay roller 313 through the relative sliding between the switching block 325 and the polarizing bracket 326. The switching handle 322 also drives the polarizing rod 306 to be inserted into the polarizing screw 305 and the relay roller 313 through the relative sliding between the switching block 325 and the zoom bracket 327. The zoom rod 307 is driven to be inserted into the first power roller 316 and the zoom screw 308, and then the relay roller 313 drives the polarizing screw 305 to rotate, the first power roller 316 drives the zoom screw 308 to rotate, the polarizing screw 305 drives the polarizing ball 304 to slide horizontally, the zoom screw 308 drives the zoom ball 302 to slide horizontally, the polarizing ball 304 drives the first convex lens 506 in the two ink printing devices 5 to move horizontally synchronously through the V-shaped bracket 310, and the zoom ball 302 drives the second convex lens 506 in the two ink printing devices 5 to move horizontally. 7 synchronously moves, thereby realizing the polarization adjustment function or the zoom adjustment function; the two ink devices 5 are arranged in an upper and lower staggered manner in the stamping housing 301 to realize the synchronous printing of the upper and lower sides, and at the same time, it also avoids the mutual interference caused by the upper and lower paper surfaces when absorbing the powder and ink synchronously. The cleaning electric push rod 503 drives the third motor 502 to slide back and forth on the ink support 501, and the third motor 502 drives the four-prism lens 509 to extend forward to the flexible cleaning cotton 510 of the dustproof shell 504, so as to realize the rapid cleaning of the surface of the four-prism lens 509. ;

[0046] Specifically, Figure 3 , Figure 4 , Figure 5 and Fig.11As shown, the paper to be printed is aligned and inserted into the positioning bracket 401 from the front end of the printing housing 101 and the ink outlet assembly 202. At this time, the rolling ball 402 in the positioning bracket 401 will contact the upper surface and the lower surface of the paper respectively. Then the control panel 104 starts the corresponding heating resistor 405 on the side of the oil cylinder 404. The corresponding heating resistor 405 will heat up quickly after being energized. The heat dissipated will drive the residual gas in the oil cylinder 404 to expand, and the expanded gas will drive the positioning push rod 403 to extend outward through the ink, thereby driving the paper to deflect by a corresponding small distance, so as to realize the auxiliary fine-tuning function of the paper; the dead weight of the toner in the ink cartridge 201 and the suction force of the powder pump 203 will drive the toner to fill the first toner chamber 205 and the second toner chamber 207. When the surface of the photosensitive printing cylinder 512 is After the positively charged area contacts the toner at the first ink outlet 206 and the second ink outlet 208, the negatively charged toner will be adsorbed onto the surface of the photosensitive printing cylinder 512, and at the same time, the toner in the first toner chamber 205 and the second toner chamber 207 will be squeezed outward by the subsequent toner. When the toner is squeezed to the outlet of the first ink outlet 206 and the second ink outlet 208, the shapes of the first ink outlet 206 and the second ink outlet 208 will prevent a large amount of toner from falling out, thereby preventing the occurrence of powder falling. When toner needs to be added, the powder pump 203 will increase the power and suck all the remaining toner into the recovery chamber 204, thereby facilitating the replacement of toner. The receiving table 102 is used to receive printed paper. The inspection cover 103 is used to prevent foreign matter from being brought into the interior of the imprinting device 3, and the inspection cover 103 is also conducive to quick repair and maintenance.

[0047] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.12 , Fig.13 , Fig.14 and Fig.15As shown, the front blank of the paper is first pushed forward between the two second heating rollers 312 in the imprint housing 301, and the two first motors 309 drive the two first heating rollers 311 to rotate synchronously and oppositely.

The photosensitive component 505 is focused by the four-prism lens 509 and the laser emitter 508. The surface of the printing cylinder 512 is precisely irradiated, so that the irradiated area on the photosensitive printing cylinder 512 becomes a conductor and releases the positive charge, and the remaining unirradiated area retains the positive charge; then, after the positively charged area on the photosensitive printing cylinder 512 absorbs the toner, it drives the toner to the surface of the paper, and the surface of the paper is positively charged after friction with the ink outlet assembly 202. At this time, the negative charge generator 515 in the heat dissipation bracket 514 is energized to generate negative charge, and the negative charge generates a repulsive force on the toner on the photosensitive printing cylinder 512, so that the toner is adsorbed to the surface of the paper to achieve the transfer function;While the two photosensitive components 505 are rotating, the switching handle 322 in the switching component 303 is manually rotated, and the switching handle 322 drives the switching block 325 to slide at the lower end of the switching base 324. At this time, the switching handle 322 drives the polarizing rod 306 to be inserted into the polarizing screw 305 and the relay roller 313 through the relative sliding between the switching block 325 and the polarizing bracket 326, and the relative rotation between the polarizing bracket 326 and the polarizing connector 328. The switching handle 322 also drives the switching block 325 to slide on the switching block 325. The zoom rod 307 is inserted into the first power-on roller 316 and the zoom screw 308 by relative sliding between the zoom bracket 327 and the zoom joint 329, and then the relay roller 313 drives the polarizing screw 305 to rotate, the first power-on roller 316 drives the zoom screw 308 to rotate, the polarizing screw 305 drives the polarizing ball 304 to slide horizontally, the zoom screw 308 drives the zoom ball 302 to slide horizontally, and the polarizing ball 304 passes through the V-shaped bracket 310. The first convex lenses 506 in the two ink devices 5 are driven to move synchronously, and the zoom ball 302 drives the second convex lenses 507 in the two ink devices 5 to move synchronously, thereby realizing the polarization adjustment function or the zoom adjustment function; the two ink devices 5 are arranged in an upper and lower staggered manner in the stamping housing 301 to realize the synchronous printing of the upper and lower surfaces, and at the same time, it also avoids the mutual interference caused by the upper and lower paper surfaces when absorbing powder and ink synchronously; the cleaning electric push rod 503 drives the third motor 502 to slide back and forth on the ink support 501, The third motor 502 drives the four-prism lens 509 to extend forward to the flexible cleaning cotton 510 of the dustproof shell 504, and the flexible cleaning cotton 510 will sweep the dust on the four-prism lens 509 to quickly clean the surface of the four-prism lens 509; the dust box 511 is used to store the fallen dust; the positioning slot 323 is used to switch the positioning of the rotating handle 322; the third motor 502 also drives the four-prism lens 509 to rotate at a constant speed; the heat dissipation rotating cylinder 513 and the heat dissipation bracket 514 are used to dissipate heat inside the photosensitive printing cylinder 512.;
