The working principle of the scheme is briefly described as follows:
as shown in fig. 1, in the present invention, before the dual head inkjet printer is used, a first head P1 and a second head P2 of the inkjet printer are respectively disposed above a first cable and above a second cable of a dual parallel cable, a horizontal distance between P1 and the first cable is X1, a vertical height between P1 and the first cable is S1, a horizontal distance between P2 and the second cable is X2, a vertical height between P2 and the second cable is S2, P1 and P2 are respectively disposed on both sides of the dual parallel cable to be printed, a deflection angle Δ 1 of ink droplets of the first head and the second head is arctan X1/S1, a Δ 2 is arctan X2/S2, a charging voltage when a deflection angle Δ 1 of ink droplets in P1 is obtained by applying different voltages to a charging pole of the first head P1, a charging voltage when a deflection angle P2 of the ink droplets in the second head is obtained as a deflection angle Δ 1, applying a corresponding voltage to a charging electrode of a P1 nozzle, starting a P1, timing by a timer when starting, when an ink droplet sprayed by the P1 nozzle reaches a first cable ink spraying point, the ink droplet shields an infrared receiving device to receive infrared rays, the infrared receiving device sends a signal to the timer, stopping timing to obtain T1, and similarly, applying a corresponding voltage to the charging electrode of the P2 nozzle, starting a P2, timing by the timer when starting, when an ink droplet sprayed by the P2 nozzle reaches a second cable ink spraying point, the ink droplet shields the infrared receiving device to receive infrared rays, the infrared receiving device sends a signal to the timer, stopping timing to obtain T2, because the distance between an ink box and the P2 nozzle is farther, T2 is larger than T1, obtaining an error time T3, then starting the P2 nozzle, starting the P2 nozzle by the timer when starting, when the time reaches the time T3, the jet printer restarts the P1 nozzle, if the ink drops of the P1 nozzle and the P2 nozzle reach the first cable ink jet point and the second cable ink jet point at the same time, the synchronous debugging is completed; after synchronous debugging is finished, the position of a second detection point is obtained by multiplying the average speed V of the cable moving by P1 according to the motor driving, the position of a first detection point is obtained by multiplying the average speed V by V according to T3, namely when the double-side-by-side cable passes through the first detection point, the jet printer starts a P2 spray head to start ink jet, when the double-side-by-side cable passes through the first detection point, the jet printer controls a P1 spray head to start ink jet, and when the cable reaches the ink jet points of the first spray head and the second spray head, ink drops just reach the cable to perform jet printing; of course, except that the distance between the first detection point and the second detection point is not changed, the distance between the second detection point can be set by a user according to the position on the cable where the user wants to print.
Further, in step S6, the distance between the first detection point and the second detection point is X3, X3 is obtained by multiplying the moving speed V of the cable by T3, the distance between the second detection point and the ink-jet point on the track of the first head P1 is X4, and X4 is obtained by multiplying the moving speed V of the cable by T1, so long as the distance X3 between the first detection point and the second detection point is fixed, it can be ensured that printing is synchronized during printing, as for the distance X4, if printing is started without the need of the head of the cable, the distance adjusted by X4 can be reduced by the user, and thus printing will not be started from the head of the double-side-by-side cable.
Further, in step S3, an infrared transmitting device and an infrared receiving device are disposed on the same horizontal plane of the first cable ink jet dot and the second cable ink jet dot and are disposed on one side of the first cable ink jet dot and the second cable ink jet dot, and an infrared receiving device is disposed on the other side of the first cable ink jet dot and the second cable ink jet dot.
Furthermore, in step S2, the charging electrode applies negative charges to the ink droplets in proportion to the voltage of the charging electrode, the deflection plate is composed of positive and negative plates, and positive and negative voltages are applied in the middle, when the ink droplets pass through the middle of the positive and negative plates, the ink droplets deflect, the deflection angle is determined by the negative charges carried by the ink droplets, because the width of the nozzle is larger than that of the cable, the dual-nozzle jet printing cannot be arranged just above the cable to be jet printed like the single-nozzle jet printing, the ink droplets can be jet printed when falling vertically, and the ink droplets can be emitted to the cable accurately only when the deflection plate is used to deflect the ink droplets.
Further, in step S5, the motor drive roller rotates, is provided with the guide rail on the roller, and two side by side cables are through the transmission of each roller on the guide rail, to first cable inkjet point and the removal of second cable inkjet point, and the width of guide rail is unanimous with the width of two side by side cables, and two side by side cables are because the restriction of guide rail can not the horizontal hunting at the transmission in-process, drive two side by side cables through the roller and remove, and the cable is blocked in the guide rail, can play the fixed action to the cable, guarantees the uniform motion of cable simultaneously.
Furthermore, the inkjet printer is also connected with a timing module, a first time parameter is preset in the timing module, the first time parameter is the inkjet printer code spraying interval time, when a row of fonts are printed on the cable at intervals, the desired interval distance can be obtained by setting the time of the first time parameter and then according to the moving speed of the cable.
Furthermore, the ink jet numbering machine is also connected with a display screen and a keyboard, the printing content can be input through the keyboard, the content to be printed can be directly input through the keyboard, external introduction is not needed, the printing content can be temporarily changed, and the ink jet numbering machine is applied to emergency situations.
Furthermore, a third detection point is further arranged in the moving path of the double parallel cables to the jet printing machine, the third detection point is an infrared sensor, the passing of the cables can be detected, when the infrared sensor cannot detect the passing of the cables, the fact that the cables are terminated is shown, in order to prevent ink waste, the infrared sensor sends signals to the jet printing machine, and after the jet printing machine receives the signals, the P1 spray head and the P2 spray head are respectively closed, and printing is stopped.
The foregoing is merely a preferred embodiment of the invention, it being understood that the embodiments described are part of the invention, and not all of it. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
