Abstract
This utility model discloses a unit type multi-color printing machine, mainly comprising printing basic materials drive mechanism, conveying roller, main drive mechanism, some printing edition rollers, large printing rollers, roller, frame, gearing chain. Some printing edition rollers are mounted around the large printing roller, gap can be found for basic printing materials between the large printing roller and the roller. At time of printing patterns, the printing roller driven by the main drive mechanism, large printing roller, roller and conveying roller driven by drive mechanism of basic printing materials have the same linear speed, and the driving mechanism of basic materials is under the control of the controller. This utility model is in possession of many advantages, such as one off printing, accurate over printing, fast printing, no replacement of printing edition roller, short pipelining, small working area, and double-face printing.
Description
Technical field
The utility model relates to a kind of printing machinery, specifically, is a kind of set type multicolour press.
Background technology
Existing set type multicolour press is when printing, the printing ink of each primary colours is coated each printing plate cylinder surface, each printing plate cylinder is printed on each color ink on the printing element in the mode of stack successively and forms multicolour pattern then, this kind mode of printing since be not synchronization ink printing of all kinds on printing element, but a kind of continuous-flow type operation of handover printing, be delivered to upward another kind of primary colours of next link stack printing again after promptly having printed a kind of primary colours, printing element is stretching owing to itself in the process of transmitting, the inaccurate defective in chromatography position can occur, influence printing quality; Print speed printing speed is also slower; When wherein pattern magnitude changes, then need in printing process, change the printing plate cylinder of respective cross section circumferential length, increased operation, there is ineffective defective in complex operation; Because this kind printing machine is flowing water transmission printing, so the machine streamline is longer, has taken a large amount of work areas; In addition, above-mentioned set type multicolour press can only be printed on one side.
The utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, the printing plate cylinder, the flowing water line length that solve that the trapping printing position is inaccurate, print speed printing speed slow, must change different size according to printed image size take the big difficult problem of work area, provide a kind of once Cheng Yin, the print nest position is accurate, print speed printing speed fast, needn't change printing plate cylinder, streamline is short and take little, the unit type press that can printed on both sides of work area.
The purpose of this utility model is achieved by following technical proposals.
A kind of set type multicolour press comprises printing element driving mechanism, transfer roller, main driving machine structure, several printing plate cylinders, prints big running roller, pressure roller, frame, conveyer chain.Transfer roller, several printing plate cylinders, print big running roller, pressure roller is arranged on the frame.Be wound with flexible material on the pressure roller roll body, be provided with the liner of adjustable length between flexible material and the pressure roller roll body.Several printing plate cylinders are positioned at around the big running roller of printing, and each printing plate cylinder roll surface contacts with printing big roller wheel roll surface; Print and be provided with the space of transmitting printing element between big running roller and the pressure roller; The printing plate cylinder that drives by the main driving machine structure, print big running roller, pressure roller and have identical linear velocity when the printed patterns by the transfer roller of printing element drive mechanism; The printing element driving mechanism is controlled by controller.
Described controller is a proximity switch.
Described set type multicolour press, by main driving machine structure, several printing plate cylinders, to print the main printing unit that big running roller, pressure roller, driving-chain form be two covers, with the printing element is the boundary, the location swap of two cover printing big roller wheels, several printing plate cylinders, pressure roller, driving-chain.
Before the operation, according to the liner length of each pattern length adjustment along the transversal circumference of pressure roller.After the beginning operation, under the driving of main driving machine structure, the printing ink on several printing plate cylinders is transferred on the big running roller of printing successively, and final formation will be printed on the pattern on the printing element.When the pressure roller roll surface that covers liner rotates to the contacted position of printing element, the printing element driving mechanism begins to drive transfer roller under the control of controller, begin to carry printing element by transfer roller, print big running roller and on printing element, begin printing, the pattern on the big running roller of printing is impressed on the printing element.When the pressure roller roll surface that covers liner separated with printing element, the printing element driving mechanism quit work under the control of controller, and transfer roller is no longer carried printing element.Because the main driving machine structure uninterruptedly drives when operation, printing plate cylinder shifts pattern once more on the big running roller of printing, when the pressure roller roll surface that covers liner rotates to the contacted position of printing element once more, print again again.In printing the images to the printing element process, printing plate cylinder, print big running roller, pressure roller, transfer roller and have identical linear velocity.
The utility model beneficial effect compared with prior art is, once Cheng Yin, the print nest position is accurate, print speed printing speed fast, needn't change printing plate cylinder, streamline is short and take work area little, can printed on both sides.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pressure roller circumferential section figure.
Among the figure: 1, printing element driving mechanism; 2, transfer roller; 3, main driving machine structure; 4, printing plate cylinder; 5, print big running roller; 6, pressure roller; 7, frame; 8, printing element; 9 flexible materials; 10, liner; 11, controller; 12, driving-chain; 13, pressure roller roll body.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
During operation, according to the length of each printed patterns length adjustment, after the beginning operation, under the driving of main driving machine structure 3 along the liner 10 of pressure roller 6 transversal circumference, printing ink on several printing plate cylinders 4 is transferred on the big running roller 3 of printing successively, and final formation will be printed on the pattern on the printing element 8.When pressure roller 6 roll surfaces that cover liner 10 rotate to printing element 8 contacted positions, printing element driving mechanism 1 begins to drive transfer roller 2 under the control of controller 11, begin to carry printing element 8 by transfer roller 2, print big running roller 5 and on printing element 8, begin printing, the pattern on the big running roller 5 of printing is impressed on the printing element 8.When pressure roller 6 roll surfaces that cover liner 10 separated with printing element 8, printing element driving mechanism 1 quit work under the control of controller 11, and transfer roller 2 is no longer carried printing element 8.Because main driving machine structure 3 uninterruptedly drives when operation, printing plate cylinder shifts pattern to the big running roller 5 of printing again again, when pressure roller 6 roll surfaces that cover liner 10 rotate to printing element 8 contacted positions once more, begins again to print again.In printing the images to printing element 8 processes, printing plate cylinder 4, the big running roller 5 of printing, pressure roller 6, transfer roller 2 have identical linear velocity.
