Printing machine is used for the machine of printing word and image.Modern printing machine is generally by loading, inking, coining, paper feeding
The mechanisms such as (including folding) composition.Its operation principle is：Printing plate is made in the writings and image that will first print, and is mounted in printing machine
On, then printing machine ink coated on having the place of writings and image on printing plate, then be directly or indirectly transferred to paper or other
Stock（Such as textile, metallic plate, plastic cement, leather, plank, glass and ceramics）On, to copy print identical with printing plate
Brush product.
Lining paper usually is added in printing plate, roller in printing process in printing machine, to increase the thickness of roller cylinder-packing,
So as to increasing the printing pressure between roller.Whether the size of lining paper, thickness are sprawled and are convinced, rectify and the evenness of lining paper, flat
Slippery etc. all has close ties with print quality.In order to obtain ideal printing pressure, it is desirable that sark（Such as hair
Felt, worsted fabric, lining paper etc.）Have certain hardness, finish and flatness.In the prior art, lining paper is worked by front end
The rotary power of roller, to drive lining paper to rotate conveying on reel, itself is unpowered on reel for lining paper, while also not having
Standby tension, easily occurs that lining paper is crooked, gauffer in transmission process, or even fracture, and lining paper conveying is uneven, influences the print of printing machine
Brushing effects.
A kind of draw sheet tension mechanism is disclosed in the prior art（Patent No. CN201220530431.5）It solves
Above-mentioned technical problem.This draw sheet tension mechanism uses gear drive and motor as transmission mechanism and actuating unit,
Due to device fabrication, in actual use, due to power and transmission problem, shaft has irregular vibrations, this
Kind vibrations bring the tension fluctuation on lining paper.
Invention content
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of printing machine tension
Device finely tunes tension, improves tension stability.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of printing machine tensioner, including rack
（9）, the rack（9）Both ends pass through support base respectively（6）Shaft is installed（4）, the shaft（4）On be wound with lining paper
（8）, the shaft（4）One end gear drive is installed（3）；Positioned at rack（9）Side be provided with stretching and and machine
Frame（9）Vertical holder（7）, the holder（7）On pass through bearing（2）Magnetic powder brake is installed（1）, the magnetic powder brake
（1）Output end and gear drive（3）Driven wheel be co-axially mounted, be located at rack（9）Side is also equipped with control magnetic powder
Brake（1）The tension controller of tension（5）；The shaft（4）The upper tensioned micromatic setting of socket.
Optimization, above-mentioned printing machine tensioner, the tension micromatic setting includes sleeve（10）, sleeve（10）For metal
Hollow tubular, sleeve（10）It is socketed on shaft（4）Outside；The sleeve（10）Inner wall and lining paper（8）Between be provided with several bullets
Property supporting rod（11）, elastic supporting bar（11）Both ends respectively with sleeve（10）Inner wall, shaft（4）Fixed welding.
Optimization, above-mentioned printing machine tensioner, the elastic supporting bar（11）For the elastic metallic bar of arc.
Optimization, above-mentioned printing machine tensioner, the sleeve（10）Silica gel sheath is socketed on surface（12）.
Optimization, above-mentioned printing machine tensioner, the silica gel sheath（12）Thickness be more than sleeve（10）The 15% of outer diameter.
Optimization, above-mentioned printing machine tensioner, the magnetic powder brake（1）With tension controller（5）By electrically connecting
It connects.
In shaft in the technical solution of the application（4）Upper socket sleeve（10）, pass through elastic supporting bar（11）Elasticity become
Shape and elasticity are restored to absorb lining paper（8）On tension fluctuation, improve lining paper（8）Tension stability.
Work as lining paper（8）When upper tension increases, lining paper（8）It is applied to sleeve（10）On pressure increase, elastic supporting bar
（11）Lining paper is absorbed by flexible deformation（8）On tension.Work as lining paper（8）On tension reduce when, lining paper（8）It is applied to sleeve
（10）On pressure reduction, elastic supporting bar（11）Restore to support lining paper by elasticity（8）Improve lining paper（8）The tension on surface.
No matter making widely known lining paper（8）When being influenced by which kind of and generating the increase and reduction of tension, pass through elastic supporting bar（11）Effect
It is finely adjusted, to ensure lining paper（8）The tension stability on surface.
