Description
Technical field
The utility model belongs to printer technology field, and in particular to a kind of new type printing press device.
Background technique
With the swift and violent promotion of scientific and technological level, fast pace has become a big characteristic of today's society, and printing industry is also
In this way, the printed matter of high quality, the prior unremitting pursuit to print speed printing speed can be printed out by not being intended merely to its product, it is desirable to
While meeting client and consumer to efficient production requirement, enterprise competitiveness is promoted.Currently, the print speed printing speed of offset printing equipment
18200 printed sheets at this stage/hour is promoted to from 3600 previous printed sheets/hour.However, getting a promotion in print speed printing speed
While, the working performance and stability of offset printing equipment are also required to meet higher requirement, wherein the plate clamp structure of plate cylinder
It plays an important role to working efficiency is improved.
According to loading form, it is several that plate cylinder clamp bar can be divided into fixed clamp bar, quick plate clamp, semi-automatic clamp bar.
Wherein fixed clamp bar and quick plate clamp on offset press using relatively broad.
Fixed clamp bar possesses two clamp bars (upper clamp bar and lower clamp bar) up and down, and has been evenly distributed on each clamp bar multiple tight
Version screw, is additionally provided with multiple adjusting bolts on upper clamp bar, and adjusting bolt is the gap for adjusting upper clamp bar and lower clamp bar.
When changing printing plate, tight version screw is unclamped first, upper and lower clamp bar can separate automatically under the action of the spring at this time, be packed into print
Version, while tight version screw being tightened again, after band printing plate is clamped, turn draws version screw to carry out drawing version operation.
Board clamp device all shores printing plate clamping by spring strength, and lead to during loading printing plate is produced
The frictional force locking printing plate position between clamp bar and printing plate is crossed, provides stable chromatography for printing.
However clamp bar works in high pressure and the environment of friction for a long time, be easy to cause abrasion, leads to plate slap, it cannot
Stable printing chromatography is improved, printing defective, bad product is caused to increase, printing quality can not also improve.In the process specifically produced
In, just there is the clamp bar of more than half to need to dismantle progress blasting treatment in printing machine servicing operations half-yearly, and dismount one group
Clamp bar just needs the time of half a day, seriously affects production efficiency.
It unloads the speed of version and plate change in order to improve in the prior art and has also carried out some technique improvements, such as application No. is
201220723090.3 utility model patent discloses a kind of printing board clamp device and printing machine, including top board, lower platen,
