Abstract
The utility model relates to a static electricity eliminating device for digital ink jet. The static electricity eliminating device for digital ink jet comprises a guide roller used for conveying a web, a gear on a coder is driven by a gear on the guide roller in a meshing transmission mode, a signal is generated by the coder and is transmitted to an ink jet control unit, and the coder is connected with a static electricity eliminator earthed. Because gear transmission is adopted for the speed measurement mode of the coder of the static electricity eliminating device for digital ink jet, the jump phenomenon will not exist, static electricity generated by friction between the web and the guide roller and static electricity generated by friction between the gears can be eliminated through the static electricity eliminator, the static electricity is prevented from affecting signal transmission of the coder, the deviation between the web speed measured through the coder and the actual speed is avoided, and good effect of ink-jet printing is achieved.
Description
Technical field
The utility model relates to a kind of digital ink-jet with eliminating electrostatic equipment.
Background technology
At present, ink-jet system on the market all forms by printing control station, ink gun, black sign degree transducer and speed measuring coder, and wherein testing the speed of encoder realized by rubber wheel contact friction transmission and two kinds of methods of gear drive substantially.These two kinds of kinds of drive respectively have merits and demerits: (1) rubber wheel contact friction transmission can not produce static, but rubber wheel easily weares and teares and contact friction transmission meeting is beated because of the foul on deflector roll, thereby affects ink jet printing; (2) gear drive is more stable, do not have jumping phenomena, but the friction of paper and deflector roll and the friction between gear easily produce static, affect the signal transmission of encoder, cause web velocity that encoder measures and actual deviation arranged, finally affecting the ink jet printing position.
Therefore, for the situation of said gear transmission, be necessary to design a kind of elimination electrostatic equipment, to eliminate paper, the fricative static of deflector roll and the fricative static of gear, make ink jet printing reach good effect.
The utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement, and technical problem to be solved in the utility model is to provide a kind of digital ink-jet with eliminating electrostatic equipment.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of digital ink-jet is with eliminating electrostatic equipment, comprise the deflector roll for delivery of roll web, gear on described deflector roll drives the gear on encoder by engaged transmission, described encoder produces signal and is transferred to the ink-jet control unit, described encoder is connected with Xelminator, described Xelminator ground connection.
In further technical scheme, an end of the static elimination bar of described Xelminator is connected on the encoder shell, and the other end of described static elimination bar is fixed on wallboard.
In further technical scheme, described static elimination bar is close to the reel paper.
Compared with prior art, the utlity model has following beneficial effect: this digital ink-jet adopts more stable gear drive by the encoder mode of testing the speed of eliminating electrostatic equipment, do not have jumping phenomena, it can eliminate roll web and the fricative static of deflector roll and the fricative static of gear by Xelminator, avoided the signal transmission of electrostatic influence encoder, guarantee web velocity and actual zero deflection that encoder is measured, make ink jet printing reach good effect.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
The accompanying drawing explanation
The transmission principle figure that Fig. 1 is the utility model embodiment.
The structural representation that Fig. 2 is the utility model embodiment.
In figure: 1-roll web, 2-deflector roll, 3-gear, 4-encoder, 5-Xelminator, 51-static elimination bar, 6-wallboard, 7-ink gun, 8-dryer.
Embodiment
As shown in Figure 1 and 2, a kind of digital ink-jet is with eliminating electrostatic equipment, comprise the deflector roll 2 for delivery of roll web 1, gear 3 on described deflector roll 2 drives the gear on encoder 4 by engaged transmission, described encoder 4 produces signal and is transferred to the ink-jet control unit, and described encoder 4 is connected with Xelminator 5, described Xelminator 5 ground connection, make all static on Xelminator 5 all import the earth, finally reach the effect that static is eliminated.
In the present embodiment, one end of the static elimination bar 51 of described Xelminator 5 is connected on encoder 4 shells, so that the fricative static of gear 3 is transferred to static elimination bar 51 by encoder 4 shells, the other end of described static elimination bar 51 is fixed on wallboard 6 by rectangular paster, so that fixing and adjusting static elimination bar 51 positions; Described static elimination bar 51 is close to 1 of roll web, to eliminate the fricative static of reel paper.
The operation principle of the present embodiment is as follows: roll web 1 is in course of conveying, driving deflector roll 2 by frictional force rotates, deflector roll 2 is passed to the gear above encoder 4 by the gear 3 above it by power, thereby the gear above encoder 43 rotates the generation signal and is transferred to ink-jet control unit (rotation generation current signal, measure the speed that roll web 1 advances), last ink gun 7 is in the accurate location spray printing information on roll web 1 surface, and on 9 pairs of roll webs of dryer, the information of spray printing is carried out drying.Simultaneously, the fricative static of gear 3 is transferred to static elimination bar 51 by encoder 4 shells, and by 1 of roll web with the fricative electrostatic transfer of deflector roll 2 to static elimination bar 51, finally all static on static elimination bar 51 are all imported to the earth, finally reach the effect that static is eliminated.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
