Description
Technical field
The utility model relates to a kind of cardboard box printing machine, particularly relates to the printing element for cardboard box printing.
Background technology
Particularly printing word or pattern on millboard on paper, thus allow product package appearance there is abundant performing content, and the machine of realizing this process is commonly referred to as cardboard printing machine or carton press.On a cardboard, be called multicolor overprint with the repeat print word of same area, same shape or the printing process of figure of different colors.And at present in order to enrich the color of packaging external appearance part, often adopt the mode of chromatography to carry out colored printing at packaging external appearance part, as shown in Figure 1, it is the front schematic view with the cardboard with multicolour pattern 21 2 of multicolor overprint method making, when the multicolour pattern 21 that need to make on described cardboard 2, need to print specific color as A point region time, need to repeat also exactly in the different color of a-quadrant chromatography.If but when dislocation appears in the position of chromatography, A point region will occur that ghost phenomena causes pattern very fuzzy, thereby will affect the printing effect in A point region, even cause single piece of cardboard 2 printing qualities defective and scrap.For this reason, the chromatography precision of printing machine becomes printed matter important factor in order whether up to standard such as determining cardboard.
As shown in Figure 2, it is the basic structure schematic diagram of current conventional multicolor overprint carton press, be composed in series by least three printing elements that are arranged side by side (1a, 1b, 1c), can be successively to putting at least three kinds of different colors of same area printing of cardboard 16 thereon.The structure of described printing element (1a, 1b, 1c) is basic identical,, take described printing element 1a as example, the structure of described printing element 1a is briefly explained now.Described printing element 1a comprises gantry type frame 17, and be arranged on the anilox roll 11 in described frame 17, be installed on described anilox roll 11 belows and the printing plate cylinder 12 of the contact of can mutually rolling, be installed on the work roller platen 13 under described printing plate cylinder 12, be installed on respectively charging workbench 14 and the discharging workbench 15 on described roller platen 13 sides, the top working face of described roller platen 13 and described charging workbench 14, discharging workbench 15 is substantially in same level, and described charging workbench 14, in the space that the described frame 17 that discharging workbench 15 is hidden in completely defines, drying mechanism 18 is also installed above described charging workbench 14.Thereby described charging workbench 14 and discharging workbench 15 not only can paperboard conveyings and in course of conveying, can be adsorbed cardboard by the principle of vacuum suction and prevent that dislocation from appearring in cardboard in course of conveying.Cardboard 16 to be printed is transported to the gap between described printing plate cylinder 12 and roller platen 13 by described charging workbench 14 and prints after the first color, be transported to described discharging workbench 15 again and transfer out hot blast through described drying mechanism 18 printed patterns on described printed paperboard 16 is dried, the printing element (1b, 1c) of finally sending into successively below prints second, third kind of other color etc.
In existing cardboard printing equipment, there are several problems to fail all the time to solve preferably.The firstth, continue printing precision problem, and all charging workbench 14, discharging workbench 15 that one of key factor that affects continuation printing precision is flatness in printing process of the described charging workbench 14, discharging workbench 15 of each printing element (1a, 1b, 1c) and successive printing element (1a, 1b, 1c) need to be in identical working level height; The secondth, print speed printing speed problem, because cardboard is thicker hard, and be that single casing independently prints, transmittance process not only can not be as the materials such as newspaper continuity transmission and also speed fast, and the ink of cardboard absorption is not easy to be dried, the drying time needing is long, if but on identical stroke speed too high, certainly will shorten drying time, thereby limit print speed printing speed.For this reason, above-mentioned two problems is actually interactional two factors.
In addition, because described charging workbench 14, discharging workbench 15 are hidden in described frame 17 completely, so input and output material stroke, through the described cardboard 2 of preliminary printing from a upper printing element be transported to next printing element stroke very short, between former and later two printing process, drying time is just very of short duration for this reason, tend to cause the pattern of described cardboard 2 also not dry completely and just entered next printing element for this reason, be very easy to like this make undried pigment to be coated with and open, affect printing effect; In order to prevent this problem, often must control the speed of printing, thereby guarantee to be reserved with enough drying times.
Summary of the invention
The variety of issue existing for prior art, the design pays close attention to several problems.First problem, due to various packings calliper difference used, in order to strengthen the versatility of equipment, we need to accomplish adjustable by the gap between the described printing plate cylinder 12 shown in Fig. 2 and the described work roller platen 13 of its below.If but make described printing plate cylinder 12 motionless and allow described roller platen 13 move up and down, due to described charging workbench 14, discharging workbench 15 must be with described work roller platen 13 substantially in same working level height, they are actually and are jointly connected on same work housing for this reason, if described like this charging workbench 14, discharging workbench 15 frequently moves, be very easy to cause the distortion that is distorted of its working face, and before being difficult to guarantee, the described charging workbench 14 of rear printing element, discharging workbench 15 all remains on same level height, Second Problem, needs to find solution for improving print speed printing speed.One of one of them method is exactly the active length that lengthens described charging workbench 14, discharging workbench 15, if but described charging workbench 14, discharging workbench 15 are set to mechanism moving up and down, frequent mobile process can be aggravated the described charging workbench 14 of extension length, the torsional deformation amount of discharging workbench 15 more; The 3rd problem is how to increase work efficiency better.If the described work roller platen 13 of each printing element, described charging workbench 14, discharging workbench 15 are upper and lower adjustable structures, so not only after certain working quantity, must carry out working depth fine setting to each printing element, but also must finely tune the working level height of whole printing elements of forward and backward linking.Obvious is like this time-consuming work of requiring great effort very much.
