Description
Technical Field
The invention relates to the technical field of ink-jet printing equipment, in particular to an ink-jet printing trolley.
Background
The printing dolly of ink jet printer is bearing the printing shower nozzle, for the printing ink circuit subassembly that the shower nozzle supplies ink, adjust the gas circuit subassembly of negative pressure value in the ink circuit and control the circuit board etc. of ink jet printing process, many pipes and wire rods are used in the interconnect of ink circuit subassembly, gas circuit subassembly and circuit board, the direction of connection of these pipes and wire rods depends on the arrangement structure of each component, if arrange unreasonablely, pipe or wire rod cross winding when not only assembling, cause unnecessary waste, influence pleasing to the eye degree, arouse the increase of equipment fault rate, and can lead to the size of printing the dolly to increase, influence and print the precision.
When the ink-jet printer works normally, the ink-jet printer has higher requirements on the working temperature of ink, the working temperature of the ink is generally 23-26 ℃, when the temperature is too high, the ink is easy to volatilize, so that the ink is easy to dry, when the temperature is too low, the fluidity of the ink is poor, and the two conditions can cause the ink outlet of the nozzle to be poor, so that the printing quality is influenced. In order to solve the above problems, in the prior art, a heating and cooling device is added to the secondary ink cartridge to make the ink supplied to the print head by the secondary ink cartridge at a proper temperature. The temperature-regulating ink box of the inkjet printer, which is disclosed by the Chinese patent CN202088668U, comprises an aluminum alloy box body, a box cover, an ink input pipe and a conveying pipe which are arranged on a spray head trolley, wherein the box body is internally provided with more than four independent cavities which are arranged in a straight line, a cooling component is arranged below the box body, a heat radiation component and a heating component are arranged on the side edge of the box body, a temperature measuring probe is arranged on the box body, and the cooling component, the heat radiation component, the heating component and the temperature measuring probe are electrically connected with a temperature controller. Although the temperature that can control the ink in the second grade ink horn of above-mentioned prior art is in invariable within range, but set up cooling component, radiator unit and heating element around the second grade ink horn, increased the volume and the weight of second grade ink horn, when printing required ink kind when many, need install a plurality of second grade ink horns, this can make holistic volume of shower nozzle dolly and weight increase, influence the stability of dolly motion, and then influence the printing quality.
In the printing process of the ink-jet printer, the requirement on the printing precision of the spray head is very high, and in order to ensure the printing precision, the measures generally adopted are as follows: splicing a plurality of nozzles, mechanically adjusting the included angle between the nozzles, mechanically adjusting the parallelism between the nozzle bottom plate and a printing medium, software adjustment and the like. When installing more shower nozzles in printing the dolly, because the shower nozzle gross mass is heavier, the shower nozzle bottom plate size is great, no matter be assembly process, machining error or dead weight reason, all can lead to the position slope of shower nozzle bottom plate, still need carry out position adjustment to the shower nozzle this moment, with the drop point position accuracy of guaranteeing the shower nozzle injection point, and the angle of adjusting every shower nozzle alone is very consuming time power, and the uniformity hardly guarantees, then need guarantee on the bottom plate on the basis of shower nozzle installation accuracy wholly carry out position adjustment to the shower nozzle bottom plate. The support frame of the printing trolley in the prior art is generally formed by assembling and enclosing a back plate and a left side plate and a right side plate, a nozzle bottom plate is arranged at the bottom, and when the nozzle bottom plate is integrally subjected to angle adjustment, the rigidity of the support frame assembled in a splicing manner is difficult to ensure and easy to deform, so that the angle adjustment precision of the nozzle bottom plate cannot be reliably ensured; in the transportation process of the machine, the screws playing a role in connection and fixation are easy to loosen and even fall off, and the screws need to be installed and adjusted again, so that time and labor are wasted, and great inconvenience is caused to customers.
