A kind of double face printing apparatus
Technical field:
The present invention relates to printing machinery technical field, in particular to a kind of double face printing apparatus.
Background technology:
In printing industry, sometimes need to print the positive and negative of printing element simultaneously, but it is little sometimes to run into operating space, and need again to wear bag when changing, length consuming time, sound equipment operating efficiency, and carry out front-back two-sided printing at a relative narrow space, printed matter is easily crumpled and is difficult to guarantee product quality, for above problem, application number is that the solution of a kind of perfecting press of invention of CN201220655145.1 is as follows: the printing equipment comprising clipsheet, first drying plant, the printing equipment of printing another side, second drying plant, first drying plant and the second drying plant are double-decker one on the other, said mechanism is all arranged on body, the printing equipment that printing base is sent to clipsheet by connecting gear carries out one side printing, and the first surface of printing base is dried respectively by the first drying plant, then by the printing equipment printing another side of printing another side, then the another side of printing base is dried by the second drying plant, after oven dry by connecting gear synchronism output to subsequent processing.But the present invention still needs longer length substrate, and there is the phenomenon of skidding sideslip in by several live-roller in base material, can affect crudy unavoidably.
Summary of the invention:
For a kind of perfecting press Problems existing of invention that application number is CN201220655145.1, solution of the present invention is as follows: a kind of double face printing apparatus, comprises motor, support, platen assembly and guide roller assembly, described support comprises horizontally disposed base plate, the starting stave vertically arranged and the second riser, horizontal mounted motor on starting stave, the output of motor is connected to the camshaft of platen assembly, the other end of described camshaft is fixed on the second riser, described camshaft is provided with cam, described cam coordinates with two rolling bearings to be installed, described rolling bearing is arranged in main body, main body is rhombus, upper end and the upper connecting rod of described main body are hinged, lower end and lower connecting rod hinged, described upper connecting rod and upper fixed block hinged, described lower connecting rod and lower fixed block hinged, main body is arranged in body shaft, described body shaft is fixed on starting stave and the second riser, the bottom of fixed piece is connected to lower impression fixed block, the bottom of described lower fixed block is connected to impression fixed block, impression block is installed in the bottom of described upper impression fixed block, block is impressed under the bottom installation of described lower impression fixed block, described guide roller assembly lays respectively at the front and back end of platen assembly.
According to technique scheme, electric motor starting, cam axle can be driven, cam rotates thereupon, because cam engages with the rolling bearing of two in main body, simultaneously because body shaft is hinged on support, therefore, main body can rotate around body shaft, the top of main body by upper connecting rod and upper fixed block hinged, the bottom of main body by lower connecting rod and lower fixed block hinged, while main body reciprocally swinging, upper fixed block and lower fixed block drive lower impression block and upper impression block to move back and forth up and down respectively, so can realize simultaneously near and simultaneously away from the result of printing element, when both are simultaneously near printing element, lower impression block and upper impression block can carry out presswork to the lower surface of printing element and upper surface respectively, by the time away from printing element while of after presswork completes, guide roller continues printing element downstream transport, after this lower impression block and upper impression block carry out presswork to the other parts of printing element near printing element again simultaneously again.
The present invention eliminates and makes printing element reach the effect of printed on both sides by the mode that the delivery roll of several bending setting is carried simultaneously, avoids the problem of skidding, sideslip in the process of conveying, is conducive to the raising of printing quality.
As the explanation to the guide roller assembly in technique scheme, described guide roller assembly lays respectively at the front and back end of platen assembly, often organize guide roller assembly and comprise guide roller and support bar, the quantity of described guide roller is two, arranges up and down, described support bar is positioned at the both sides of two guide rollers, the support bar pivot joint of two guide rollers and both sides.Guide roller assembly is the assembly for smooth transport printing element, front and back end arrange guide roller assembly can transmit printing element by between upper impression block and lower impression block, make impression block and lower impression block when move toward one another by graphic-print on two faces of base material.
As the explanation to the platen assembly in technique scheme, fixed piece is connected by the first sliding bar with lower impression fixed block, the quantity of described first sliding bar is two, lays respectively at the two ends of fixed block, is fixed between described first sliding bar and upper fixed block by screw.On described first sliding bar, cover has the first sleeve and the second sleeve, first sleeve is positioned at the top of the second sleeve, described first sleeve and the second sleeve are all fixed by screws on base plate, and described base plate is between the first sleeve and the second sleeve, and the first sliding bar can move up and down through base plate.First sleeve and the second sleeve are fixed on base plate, body shaft is also articulated on support, therefore when cam axle, due to the rhombus moulding of main body, drive first sliding bar moves up and down through the first sleeve, the second sleeve and base plate by upper fixed block, drive thus lower impression block near and the motion of lower surface away from printing element, presswork can be carried out to it when instantly impressing block and substrate contact.
As further illustrating the platen assembly in technique scheme, be connected by the second sliding bar between described lower fixed block with upper impression fixed block, the quantity of described second sliding bar is two, lay respectively at the two ends of lower fixed block, fixed by screw between described second sliding bar and lower fixed block.On described second sliding bar, cover has the 3rd sleeve, and described 3rd sleeve is fixed by screws on base plate, and described base plate is positioned at the below of the 3rd sleeve, and the second sliding bar can move up and down through base plate.3rd is fixed on base plate, body shaft is also articulated on support, therefore when cam axle, due to the rhombus moulding of main body, drive second sliding bar moves up and down through the 3rd sleeve and base plate by lower fixed block, drive upper impression block away from the motion with the upper surface near printing element thus, presswork can be carried out to it when upper impression block and substrate contact.
