The core of flexible printing machine is printing element, and printing element includes that multiple colour cell, each colour cell all include
Net roller, roller and bottom roller.Flexible printing machine is when installing and change roller, so that chromatography is accurate, and contracting
Little register control scope, improves work efficiency, needs the roller of each colour cell to be all in fixing position,
On this position, the roller print of each colour cell pattern on the substrate is close to being completely superposed, and this process claims
For pre-alignment.After pre-alignment, in printing process, the roller of each colour cell is made to be imprinted on by control system
The process that pattern on stock is completely superposed is referred to as register control.
As it is shown in figure 1, tradition flexible printing machine printing element operation principle be: ink through net roller 2 ink transfer,
It is then transferred in roller 1, in last printing to printable fabric 12 (printable fabric 12 is attached on bottom roller 3),
All rotating on the material road of each colour cell upstream and downstream and be provided with deflector roll, the position of deflector roll 4 and deflector roll 5 is
Fixing, in printing process, printable fabric 12 is in tensioning state by the pressure from deflector roll.Fig. 2 illustrates
Go out single servo-drive transmission principle of traditional flexible printing machine printing element: servomotor 11 directly drives master
Moving gear 7, drives net roller, roller and bottom roller to rotate by gear drive, driving gear 7 and bottom roller gear
10 engagements drive bottom roller 3 to rotate；Driving gear 7 engages driving net roller 2 and rotates with net roller gear 9；Actively
Gear 7 engages with idle wheel 8, and idle wheel 8 engages driving roller 1 and rotates with roller gear 6, and roller 1 is in
Combined pressure state, bottom roller 3 and roller 1 jointly rotarily drive printable fabric 12 and move ahead, and the pattern in roller 1 is i.e.
It is transferred on printable fabric 12, thus completes printing.When trapping printing rule has deviation or plate change, need
Roller 1 gear side being lifted, idle wheel 8 and roller gear 6 are in de-dentation state, manually roller 1 are rotated
Certain angle realizes pre-alignment.This pre-alignment mode had both wasted manpower and time, wasted again material.
Summary of the invention

After have employed technique scheme, the pre-registration device of printer of the present utility model, due at printer
The deflector roll position adjusting mechanism that the upstream deflector roll with print couple is connected it is respectively arranged with on the wallboard of both sides；Printing
During, printable fabric is in tensioning state by the pressure from deflector roll, the bottom roller of print couple and roller
Jointly rotarily drive printable fabric to have moved ahead printing；When trapping printing rule has deviation or plate change, logical
Cross the position of deflector roll position adjusting mechanism regulation deflector roll, make deflector roll move to the direction away from printable fabric, hold
Printed material material is in releasing orientation, during pre-alignment, even if bottom roller also rotates while roller rotates, because of
Frictional force between printable fabric and bottom roller is less, and bottom roller also will not drive printable fabric to move ahead when rotating, and holds
Printed material Liao Liao road does not changes, thus does not has printable fabric to be wasted during pre-alignment, reduces and produces into
This；After pre-alignment completes, by the position of deflector roll position adjusting mechanism regulation deflector roll, make deflector roll near holding
The direction of printed material material is moved, and printable fabric is in tensioning state, Ji Kejin again by the pressure from deflector roll
The normal printing of row.
