Abstract
The utility model relates to a printing mechanism, including galley roller, black basin, doctor -bar, spring and compression roller, galley roller lower extreme soaks in black basin, galley roller both ends are equipped with the doctor -bar, the doctor -bar is the L type, and the doctor -bar is hugged closely on the surface and terminal surface of galley roller, the doctor -bar inboard is the wedge, it is continuous with the frame of printing machine that the spring is passed through at the doctor -bar both ends, galley roller top is equipped with the compression roller rather than matched with, the compression roller both ends are the step form, the utility model has the advantages of simple structure the practicality, convenient to use, the problem of having avoided printing machine oil ink misting that can be fine avoids printing the pollution problem of paper margin portion simultaneously, has higher practical value, transform with low costs, the demand of having catered to market development.
Description
Technical field
This utility model belongs to printing machinery technical field, more particularly to a kind of printing mechanism.
Background technology
Printing mechanism is mainly connected with the accessory of pressure roller and correlation by printing plate cylinder.Find in actual production, decoration
There must be the blank of more than 5mm with printing paper edge, mark is cut for Print color code, mark line and positioning, but we are in print
Swiped through journey finds that printing paper edge Jing is often contaminated with ink, and this defect not only affects attractive in appearance, has also covered sometimes colour code and mark
Note line, causes difficulty in itself to printing process；Having polluteed on effective decorative pattern for the serious point having, causes to scrap；Some pollutions
To the back side of printing paper, dark strike through is formed, positive effect has been had influence on；Ink mass is formed in edge when more serious, follow-up
Disconnected paper is scraped during dipping during easy scraping.
At this moment because pressure roller intermediate pressure is on printing paper, roll surface is clean, and pressure roller exposed portion is to be pressed in galley
On roller.As there is ink on roller surface, ink is transferred on pressure roller, under the circumference of the high-speed rotation, the ink at pressure roller two ends
To collect thicker and thicker, edge is polluted on the surface of some ink stream to printing paper；What is had clamp-ons the back side of paper, forms strike through；Due to paper
There is certain temperature in dry run, long-time ink is formed ink mass, has adhered to the edge of paper；While printing plate cylinder
Two end faces and face have thicker ink, improve production cost, it is impossible to meet the demand in market.
Utility model content
This utility model purpose is to provide a kind of simple structure to overcome the deficiencies in the prior art, is avoided that printing paper
Edge pollutes and flies the printing mechanism of ink problem.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of printing mechanism, including printing plate cylinder,
Black basin, scraping blade, spring and pressure roller；The printing plate cylinder lower end is immersed in black basin；The printing plate cylinder two ends are provided with scraping blade；It is described
Scraping blade is L-shaped, and scraping blade is close on the surface and end face of printing plate cylinder；It is wedge shaped on the inside of the scraping blade；The scraping blade two ends
It is connected with the frame of printer by spring；The pressure roller being matched therewith is provided with above the printing plate cylinder；The pressure roller two ends
In step-like.
Preferably, the material of the scraping blade is silicone rubber.
Preferably, the thickness of the scraping blade is 5mm.
Due to the utilization of above-mentioned technical proposal, this utility model has following advantages compared with prior art：
The printing mechanism of this utility model scheme, which is simple and practical, easy to use, can be very good to avoid printing
Machine oil flies the problem of ink, while avoiding the pollution problem of printing paper edge, with higher practical value, improvement cost is low, meets
The demand of market development is closed.
Description of the drawings
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further：
Accompanying drawing 1 is structural representation of the present utility model；
Partial enlarged drawing of the accompanying drawing 2 for accompanying drawing 1；
Wherein：1st, printing plate cylinder；2nd, black basin；3rd, scraping blade；4th, spring；5th, pressure roller；6th, printing paper.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of printing mechanism as shown in accompanying drawing 1-2, including printing plate cylinder 1, black basin 2, scraping blade
3rd, spring 4 and pressure roller 5；1 lower end of the printing plate cylinder is immersed in black basin 2；1 two ends of the printing plate cylinder are provided with scraping blade 3；It is described to scrape
Piece 3 is L-shaped, and scraping blade 3 is close on the surface and end face of printing plate cylinder 1；It is wedge shaped on the inside of the scraping blade 3；3 liang of the scraping blade
End is connected with the frame of printer by spring 4；The pressure roller 5 being matched therewith is provided with above the printing plate cylinder 1；The pressure roller
5 two ends are in step-like；The material of the scraping blade 3 is silicone rubber；The thickness of the scraping blade 3 is 5mm.
During actual installation, two scraping blades are close on the surface and end face of printing plate cylinder both sides with two springs respectively, are used
The ink unnecessary to scrape off printing plate cylinder edge and end face, so that thoroughly solve the problems, such as that printer flies ink.
After the thin process of pressure roller two ends car in printer so that pressure roller two ends are thus thoroughly solved in step-like
Printing paper edge pollution problem.
Printing mechanism of the present utility model, which is simple and practical, easy to use, can be very good to avoid printing machine oil
Fly the problem of ink, while avoiding the pollution problem of printing paper edge, with higher practical value, improvement cost is low, caters to
The demand of market development.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it
It is interior.
