Point.The CP2000 automatic control systems of Heidelberg company except to full machine from paper feeding, paper carrying and lead paper, inking, water delivery, plate change,
Alignment, cleaning, drying, glazing coating, dust and each working link such as collection is carried out outside preset, regulation and control and fault diagnosis,
Also have realize printing enterprise's whole production process networking, on-line normalization print before image processing data (CIP3/PPF or CIP4/
JDF data) etc. function.Into the new century, most offset press manufacturing firms all develop corresponding DI digital printers；In addition,
In order to adapt to demand of the people to high-grade chromatograp, 8 colour cells even more colour cell printeds on both sides of 10 colour cells, additional on line print
Post-processing function turns into the exploitation of all kinds of sheet-fed offset presses (including multifith, DI direct plate makers and large-scale offset press)
Trend, and technology is ripe day by day, and the type printing machine has begun to tie up a part of city for originally belonging to web press
.
The existing paper-advance unit located at printing machine body input generally by support and is rotatably arranged on support
Drive roll and driven voller form, and the cylinder surface of drive roll and driven voller is close to each other to convey paper with clamping, drive roll with from
Master gear is respectively equipped with the roll shaft of dynamic roller homonymy with being connected from gear, master gear and a drive device, from gear and master
Meshed transmission gear.And paper feed mechanism of the prior art can not be realized and automatically adjusted to adapt to the paper of different-thickness, and
Paper, which shifts, during paper feed can not also realize self-regulation, and printing effect is poor, efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of printing machine with pressure paper-advance unit is exempted from, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of printing machine is wrapped with pressure paper-advance unit is exempted from
Support is included, is respectively equipped with drive roll and driven voller on the inside of the support, the driven voller is arranged on drive roll upper end, the active
Roller, which connects, is arranged on the driving gear of support side, and the driven voller connection is arranged on the driven gear of support side, it is described from
It is dynamic that compression compensation device is additionally provided between roller upper end and support；
The compression compensation device includes sliding axle, sliding bearing, fixed block, compression spring, and the sliding axle is fixed and set
Put and be arranged in support side, the sliding bearing on sliding axle, the fixed block is arranged on sliding bearing both sides, the compression
Spring is arranged on above sliding bearing, and the sliding axle bottom is provided with circular groove, and circular groove and driven voller outer wall
Match.
Preferably, the drive roll includes roll body, and the roll body both ends set stress relief area close to the position of end,
The roll body is gradually reduced in the roll body diameter of stress relief area from center to end；The stress relief area of the roll body exists
The roll body both ends are symmetrical arranged.
Preferably, the support uses U-bracket.
Preferably, the driven voller roller wall is provided with antistatic silica gel coating.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, can realize quick
Paper feed, the compression compensation device stability of use is good, can adapt to the paper of a variety of different size thickness；In addition, this practicality is new
The drive roll structure that type uses is novel in design, can automatically adjust paper position, paper shifts during preventing paper feed, carries
High printing quality.
Brief description of the drawings
